How to use Almonds to Increase Brainpower

by Kavit Haria

As amazing as it may seem, your favorite little nut, the almond, can help boost your brainpower, stabilize your mood and even relieve the aging process. It may seem that the little miracle nut has so much to offer you will want to incorporate it into your diet as often as possible.

The almond contains phenylalanine, this is little chemical is shown to work in conjunction with our cognitive processes and supports healthy neurological function. This chemical very easily passes through our blood-brain barrier and makes our brain produce our natural mood stabilizing hormones adrenaline, noradrenaline and dopamine. These same hormones also help reduce pain in the body. While studies are still on going, it is believed that almonds may also help treat some symptoms of Parkinson’s disease.

Almonds contain another brain boosting element called nutrientriboflavin as well as L-carnitine. This little chemical is important for the brain because it helps make it possible for our brain to metabolize acetyl-L-carnitinetransferase which supports choline metabolism. Our brain utilizes choline to prevent any neuronal degeneration. The L-carnitine that is found in almonds and other nuts also helps in the release of acetylcholine, which is essential for good memory.

Along with the brain boosting power of the almond it offers other benefits as well. Studies show that by adding almonds to your diet can help with satiety and prevent weight gain. No dangerous diet pill needed, just a handful of almonds a day. Purdue University researchers have found that two servings a day did not cause weight gain or decrease our body’s efficiency.

The almond can do wonders for your heart health as well. Almonds have been shown to lower LDL. The bad cholesterol that we really don’t want and is at times hard to lower can be handled with addition of a hand full of almonds a day.

Obviously, too much of anything is never a good thing, and eating to many nuts can lead to problems such as obesity. But incorporating a handful of almonds a day into your diet can prove to be beneficial to healthy mind function.

Adrenaline Rush

By Jaime N. Soriano

There is a common notion that human beings often survive life or death and even emergency situations because of the so-called adrenaline rush. It is a situation where the processes in the human anatomy automatically react or respond to a given situation which the mind perceives to be critical.

In science, adrenaline, or epinephrine, is a hormone produced by the adrenal gland found directly above the kidney of the human body. They say that when adrenaline is secreted into the bloodstream, the hormone prepares the body for action by boosting the supply of oxygen and glucose to the brain and muscles while reducing considerably nonemergency processes in the body like that of digestion. Short bursts of physical prowess results from dilated blood vessels and air passages that makes the body pass more blood to the muscles as more oxygen are put in into the lungs in a timely and precise manner.

They say that the discovery of the adrenaline as a substance was first reported in May 1886 by American physician William Bates in the New York Medical Journal. It was Napoleon Cybulski, a Polish physiologist and a pioneer of endocrinology, who isolated and identified the substance in 1895. German chemist Friedrich Stolz, however, was the first person to synthesize the hormone artificially in 1904.

Since the hormone causes an increase in heart rate and stroke volume, constricts the small blood vessels in the skin but dilates the arterioles in skeletal muscles, the pupils and air passages, starts the breakdown of lipids in fat cells, elevates blood sugar and suppresses the immune system, they say that it is important to douse the adrenaline released in the human system after a stressful situation. Before, this is done naturally because man is habitually engaged in a lot of physical activity. But in today’s world where human exertion is less, the amount of adrenaline left in the body results in insomnia, palpitations, high blood pressure, and restive nerves.

In 1915 American physiologist Walter Bradford Cannon theorized the so-called fight-or-flight response by holding that animals react to threats through a general discharge of the sympathetic nervous system that prepares the animals either to flee or to fight. And they say that this response system was later recognized as the first stage of a general adaptation syndrome which regulates stress reaction among vertebrates and other organisms. Thus, the fight-or-flight response is often used to characterize the situation known as adrenaline rush.

To be sure there is always the adrenaline that serves as a lifeline in every severe and extemporaneous situation man is confronted with. But summoning the aid and comfort of this hormone in normal times would only mean stress, a condition that produces unneeded bodily strain and causes much of the physical maladies and human ailments known in today’s world. Unfortunately, this is how nature works.

If human beings would only heed this law of nature, they would realize that life is all about perfecting or working for that state of constant peace and tranquility in this hectic, fast-paced and crazier world. And it is all because everyone has this adrenaline that rushes automatically in times of great need.

Reality dictates that putting the adrenaline to work unnecessarily could spell the end of life.

What is Thumbs.db file and How to get Rid of it?

Thumbs.db is a system file generated automatically by Windows XP when you view the contents of a folder in “Thumbnail” or “Filmstrip” view. Thumbs.db contains a copy of each of the tiny preview images generated for image files in that folder so that they load up quickly the next time you browse that folder. Thumbs.db also stores your settings with regard to thumbnail and filmstrip view.

Despite the fact that Thumbs.db is a hidden system file, it annoys people because it tends to show up in places where it’s not wanted. Many times you’ll try to zip up a folder full of images and e-mail them to a friend or upload them to an FTP site, and Thumbs.db goes along for the ride.

To stop your computer from generating and regenerating future Thumbs.db files, do the following:
  1. Right click Start
  2. Select Explore
  3. Select Tools
  4. Select Folder Options
  5. Select View and check "Do not cache Thumbnails" and Apply


Once you click the Ok button, your computer will cease to generate Thumbs.db files. If you delete any of the existing Thumbs.db files, they will not return. Be forewarned though, if you browse a folder that contains a large quantity of image files (or extremely large image files), it will take a long time for that folder to load even if you have previously browsed it because the thumbnail images will not have been cached in Thumbs.db.

AMD Athlon 64 2000+ At 8 Watts

Today's development of the Atom processor, Intel introduced a totally new chip design that consumes very little energy. AMD had to strike back, and did so by clocking down its Athlon 64 , employing the K8 micro architecture, down to the lowest possible frequency of 1 GHz. The Athlon 64 2000+ runs with a core voltage of 0.90 volts and uses just 8 watts. As a result, the CPU easily operates without a fan. If you drop the 8 W Athlon 64 into a motherboard based on the 780G chipset, then the system hits power consumption numbers that, in our measurements, are below Intel’s Atom desktop solution. We were even able to lower the core voltage by 11%, without stability problems, and the power analyzer read lower numbers. Interestingly, AMD’s Athlon 64 2000+ processor, unlike Intel‘s Atom CPU, is not embedded in the motherboard. It can be run on any board with an AM2 or AM2+ socket.

Compared to Intel’s Atom, which runs at 1.6 GHz, the Athlon 64 2000+ is clocked at 1 GHz—60% lower. Despite this, the Athlon 64 outperforms the Atom in several benchmark tests as a result of its more efficient K8 architecture. In addition, the energy consumption of the entire system is lower, and that’s what really matters most.

Negative Ions Help us to Sleep Better

In 1969, French researcher found that the overproduction of the neurohormone serotonin caused sleeplessness and nightmares. In using a negative ion electronic air cleaner to treat a group of people experiencing sleeping problems as a result of serotonin overproduction, he found that most of them were able to sleep better.

Benefits of Negative Ions

Negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy," says Pierce J. Howard, PhD, author of The Owners Manual for the Brain: Everyday Applications from Mind Brain Research and director of research at the Center for Applied Cognitive Sciences in Charlotte, N.C.

They also may protect against germs in the air, resulting in decreased irritation due to inhaling various particles that make you sneeze, cough, or have a throat irritation.

And for a whopping one in three of us who are sensitive to their effects, negative ions can make us feel like we are walking on air. You are one of them if you feel instantly refreshed the moment you open a window and breathe in fresh, humid air.

You may be one of them if you feel sleepy when you are around an air-conditioner, but feel immediately refreshed and invigorated when you step outside or roll down the car window, Howard says. "Air conditioning depletes the atmosphere of negative ions, but an ion generator re-releases the ions that air conditioners remove.

Negative ions are created in nature with air molecules broken apart from sunlight, radiation, and moving air or water. In

The action of the pounding surf creates negative air ions and we also see it immediately after spring thunderstorms when people report lightened moods," says ion researcher Michael Terman, PhD, of Columbia University in New York.

In a study conducted by Columbia University, 25 people with SAD (Seasonal Affective Depression) sat in front of a negative ion air purifier for a half hour every morning for a month. Half the subjects were given a low level of negative ions, and the other half a high level. The higher level of negative ion treatment proved to be as effective against SAD as antidepressants, such as Prozac and Zolof, and without the side effects of these drugs.

Negative ions are odorless tasteless molecules that are breathed into our respiratory system. High concentrations of negative ions can be found in nature in mountain forests, waterfalls, and beaches where people feel energized and invigorated, which helps relieve stress, alleviate depression, boost energy.

Did You Know Negative Ion ?

Ions are molecules that have gained or lost an electrical charge. They are created in nature as air molecules break apart due to sunlight, radiation, and moving air and water. You may have experienced the power of negative ions when you last set foot on the beach or walked beneath a waterfall. While part of the euphoria is simply being around these wondrous settings and away from the normal pressures of home and work, the air circulating in the mountains and the beach is said to contain tens of thousands of negative ions - Much more than the average home or office building, which contain dozens or hundreds, and many register a flat zero.

The action of the pounding surf creates negative air ions and we also see it immediately after spring thunderstorms when people report lightened moods, says ion researcher Michael Terman, PhD, of Columbia University in New York. At the turn of the 20th century Terman, confirmed that negative ions are found in very high density in the basin of waterfalls where we feel especially refreshed and re-energized.

USB Cable Length Limitations

USB Cable Length Limitations:

The USB specification limits the length of a cable between full speed (or high speed) devices to 5 meters (16 feet 5 inches) and for low speed devices the limit is 3 meters (9 feet 10 inches). This means you can't just connect a bunch of extension cable together and run them 30 feet to another room but you can say connect a 6 foot and 10 foot cable for a total of 16 feet.

Most USB products are full speed (or high speed USB 2.0) and have the 5 meter limit. Low speed devices are generally keyboards and mice. If you would like more information on the technical side of USB you can search the internet for information on the USB specification (sorry eBay does not allow links in guides otherwise I would include one).

In order to go beyond these limits you need to use USB hubs, USB active extension cables or USB over Ethernet products.

USB Hubs:

You can use extension cables and up to 5 USB hubs connected together to extend USB's range up to 30 meters (up to 27 meters for low speed devices). The distance between each hub can be no more than 5 meters.

Active Extension Cables:

USB active extension cables contain electronics which regenerate the USB signal. These cables are essentially 1 port USB hubs and will allow you to go up to 30 meters (up to 27 meters for low speed devices) buy connecting up to five active extension cables together (4 cables if you are connected to a USB hub).

USB Over Ethernet:

There are USB Over Ethernet hubs but I was to find very little documentation or other information on them that was useful. What did stand out about these devices is that they are hard to find, expensive and you are still generally limited to a maximum of 30 meters.

What Is Negative Ion?

Negative Ion is an atomic or molecular system with an excess of negative charge due to the capture of additional electrons. Negative Ions are also called anions.

Did Your Know the Eye Parts?

Eye Parts?

The eye has many parts. Some of the main parts are listed and described below.

Lens
  • The transparent crystalline lens of the eye is located immediately behind the iris.
Cornea
  • The cornea is a transparent dome which serves as the outer window of the eye. The cornea is the most powerful structure focusing light entering the eye.
Retina
  • The retina is the innermost layer of the eye. It is composed of nerve tissue which senses the light entering the eye.
  • The retina sends impulses through the optic nerve back to the brain, which translates the impulses into images that we see.
  • There are 4 types of light-sensitive receptors found in the retina
  1. rods
  2. cones that absorb long-wavelength light (red)
  3. cones that absorb middle-wavelength light (green)
  4. cones that absorb short-wavelength light (blue)
Pupil
  • The pupil is the hole in the center of the eye where light passes through.
Iris
  • The iris is the colored part of the eye. It is a thin diaphragm composed mostly of connective tissue and smooth muscle fibers. The iris lies between the cornea and the crystalline lens.
Optic nerve
  • The optic nerve is a continuation of the axons of the ganglion cells in the retina. It acts acts like a cable connecting the eye with the brain.
  • The optic nerve is also called the cranial nerve II.
Sclera
  • The sclera is the white, opaque portion of the eye. It provides protection and serves as an attachment for the extraocular muscles which move the eye.

The Banana Secrets

The banana is an important source for energy, health and nutrition. New research shows that the banana also can prevent and help cure some of the medical conditions we deal with.

One large banana, about 9 inches in length, packs 602 mg of potassium and has only 140 calories. That same banana also has 2 grams of protein and 4 grams of fiber.

The banana provides energy that can help us keep fit. Bananas can also help overcome or prevent a substantial number of illnesses and conditions. Don't overlook bananas in your diet.

Energy
Because it contains three natural sugars, sucrose, fructose and glucose, combined with fibre, a banana gives us an instant, sustained and substantial boost of energy. Research has shown that just two bananas provide enough energy for a strenuous 90-minute workout. No wonder the banana is the number one fruit with the world's leading athletes.

Depression
According to a recent survey of people suffering from depression undertaken by MIND, many felt much better after eating a banana. This is because bananas contain tryptophan, a type of protein that the body converts into serotonin. Serotonin is known to make you relax, improve your mood and generally make you feel happier.

PMS (Premenstrual syndrome)
The vitamin B6 bananas contain regulates blood glucose levels, which can affect your mood. Forget the pills -- eat a banana.

Anemia
Because bananas are high in iron, they can stimulate the production of hemoglobin in the blood and help prevent anemia.

Blood Pressure
The banana has the ability to ward off high blood pressure and stroke. This unique tropical fruit is extremely high in potassium yet low in salt, making it useful in lowering blood pressure.

Brain Power
Researchers working with 200 students at a Middlesex school showed that students did better on their exams by eating bananas at breakfast, break, and lunch to boost their brain power. The potassium-packed banana can assist learning by making pupils more alert.

Constipation
Because they are high in fiber, bananas in the diet can help restore normal bowel action without the use of laxatives.

Hangovers
A quick cure for a hangover is a banana milkshake, sweetened with honey. The banana calms the stomach and, with the help of the honey, builds up depleted blood sugar levels, while the milk soothes and re-hydrates your system.

Morning Sickness
Snacking on bananas between meals allays morning sickness and helps to keep blood sugar levels up.

Overweight and stress
Studies at the Institute of Psychology in Austria found pressure at work leads to gorging on comfort food like chocolate and chips. Looking at 5,000 hospital patients, researchers found the most obese were more likely to be in high-pressure jobs. The report concluded that, to avoid panic-induced food cravings, we need to control our blood sugar levels by snacking on high carbohydrate foods every two hours to keep levels steady.

Ulcers
Bananas neutralize over-acidity and reduce irritation by coating the lining of the stomach.

Temperature control
Some cultures see bananas as a "cooling" fruit that can lower both the physical and emotional temperature of expectant mothers. In Thailand, for example, pregnant women eat bananas to ensure their baby is born with a cool temperature.

Smoking
If you are trying to give up smoking, the vitamins B6 and B12 in bananas, as well as the potassium and magnesium, help the body recover from the effects of nicotine withdrawal.

Stress
Potassium is a vital mineral which helps normalize the heartbeat, sends oxygen to the brain and regulates your body's water balance. When we are stressed, our metabolic rate rises, and our potassium levels fall. These can be rebalanced with the help of a high-potassium banana snack.

Strokes
Research published in "The New England Journal of Medicine," concluded that eating bananas as part of a regular diet reduced the risk of death by strokes as much as 40%.

Early life of Pope John Paul II

The early life of Pope John Paul II covers the period in his life from his birth in 1920 to his ordination to the priesthood in 1946.

Karol Wojtyla at 12 years old Karol Jozef Wojtyla was born on 18 May 1920 in Wadowice near the city of Krakow in southern Poland, son of a former officer in the Austrian Habsburg army whose name was also Karol Wojtyla, and Emilia Kaczorowska. According to popular Wadowice legend, Emilia used to tell fellow townsfolk that her Karol would be "a great man one day." As a child Karol was called Lolek by friends and family.

His mother died during childbirth in 1929. On hearing about her death, he composed himself and said, "It was God's will." After Emilia's death, his father, an intensely religious man who did most of the housework, brought up Karol so that he could study. His youth was marked by intensive contacts with the then-thriving Jewish community of Wadowice.

His brother Edmund, also known as Mundek, died of scarlet fever contracted from a patient at the age of 26 in 1932. His only other sibling, a sister, died in infancy before Karol was born.

He practiced sports during his youth, being particularly athletic. He often played football (soccer), as a goalkeeper, and was a supporter of Polish club Cracovia Krakow.

Papal biographer George Weigel recalls that when Karol was around fifteen a young person playfully pointed a gun at him not realizing that it was loaded. On pressing the trigger the gun fired and narrowly missed the target. He would escape from other near death incidents as a young seminarian and later as Pope.

University
In the summer of 1938, Karol Wojtyla and his father left Wadowice and moved to Krakow, the former capital of Poland, where he enrolled at the Jagiellonian University in the autumn semester. In his freshman year, Wojtyla studied Philology, Polish language and literature, introductory Russian, and Old Church Slavonic. He also took private lessons in French. He worked as a volunteer librarian and did compulsory military training in the Academic Legion. At the end of the 1938-39 academic year, he played Sagittarius in a fantasy-fable, The Moonlight Cavalier, produced by an experimental theatre troupe.

In his youth he was an active person, and learned as many as twelve languages. By the time he was Pope he spoke ten languages fluently: Polish, Slovak, Russian, Italian, French, Spanish, Portuguese, German, Ukrainian and English, beside his good knowledge of Ecclesiastical Latin.

The Second World War
In September 1939, Germany invaded Poland, and the country was subsequently occupied by German and Soviet forces. At the outbreak of War, Karol and his father fled eastwards from Krakow with thousands of other Poles. They sometimes found themselves in ditches, taking cover from strafing Luftwaffe aircraft. After walking 120 miles, they learned of the Russian invasion of Poland and were obliged to return to Krakow. In November, 184 academics of the Jagiellonian University were arrested and the university suppressed. All able-bodied males had to have a job.

In the first year of the war Karol worked as a messenger for a restaurant. This light work enabled him to continue his education and theatrical career and in acts of cultural resistance. He also intensified his study of French. From the autumn of 1940 Karol worked for almost four years as a manual labourer in a limestone quarry, and was well paid. His father died in 1941 because of a heart attack. In 1942, he entered the underground seminary run by Cardinal Sapieha, the archbishop of Krakow. B'nai B'rith and other authorities have testified that he helped Jews find refuge from the Nazis.

On 29 February 1944, Karol was walking home from work at the quarry when he was knocked down by a German truck. The German officers tending the injured Wojtyla, and the decision to commandeer a passing truck for use as an ambulance for the unconscious patient, is in sharp contrast to the harshness normally expected from the occupying forces during this period. He spent two weeks in hospital and suffered severe concussion, numerous cuts and a shoulder injury. This accident and his survival seemed to Wojtyla a confirmation of his priestly vocation. In August 1944, the Warsaw uprising began, and the Gestapo swept the city of Krakow on 6 August, "Black Sunday", rounding up young men to avoid a similar uprising there. Wojtyla escaped by hiding behind a door as the Gestapo searched the house he lived in, and escaped to the Archbishop's residence, where he stayed until after the war.

On the night of 17 January 1945, the Germans quit the city. The seminarians reclaimed the old seminary, which was in ruins. Wojtyla and another seminarian volunteered for the odious task of chopping up and carting away piles of frozen excrement from the lavatories. In the same month of that year, Wojtyla personally helped a 14 year old Jewish refugee girl named Edith Zierer who had run away from a Nazi labor camp in Częstochowa. Zierer was attempting to reach her family in Krakow but had collapsed from cold and exhaustion on a train platform in Jędrzejw. No one helped but Wojtyla who approached her. Wojtyla gave Zierer some hot tea caca and food, personally carried her to a train and accompanied her to Krakow. Zierer credits Wojtyla for saving her life that day. In the chaos of post-war Poland they became separated and Zierer would not hear of her benefactor again until she read that he was elected as the Pope in 1978.

Pope John Paul II

John Paul II (Latin: Ioannes Paulus PP. II, Italian: Giovanni Paolo II, Polish: Jan Pawel II) Karol Jozef Wojtyla. born: (18 May 1920 - 2 April 2005) reigned as the 264th Pope of the Roman Catholic Church and Sovereign of the State of the Vatican City from 16 October 1978, until his death, almost 27 years later. His was the second-longest pontificate after Pius IX's 32-year reign. He has been the only Polish pope, and was the first non-Italian pope since the Dutch Adrian VI in the 1520s.

John Paul II was Pope during a period in which the Catholic Church's influence declined in developed countries but expanded in the Third World. During his reign, the pope traveled extensively, visiting over 100 countries, more than any of his predecessors. He remains one of the most-traveled world leaders in history. He was fluent in numerous languages: his native Polish and also Italian, French, German, English, Spanish, Croatian, Portuguese, Russian and Latin. As part of his special emphasis on the universal call to holiness, he canonized a great number of people.

He beatified 1,340 people (some listed here), more people than any previous pope. The Vatican asserts he canonized more people than the combined tally of his predecessors during the last five centuries, and from a far greater variety of cultures. Whether he had canonized more saints than all previous popes put together, as is sometimes also claimed, is difficult to prove, as the records of many early canonizations are incomplete, missing, or inaccurate. However, it is known that his abolition of the office of Promotor Fidei ("Promoter of the Faith") streamlined the process.

Common Cooking Spice shows Promise in Combating Diabetes and Obesity

Turmeric, an Asian spice found in many curries, has a long history of use in reducing inflammation, healing wounds and relieving pain, but can it prevent diabetes? Since inflammation plays a big role in many diseases and is believed to be involved in onset of both obesity and Type 2 diabetes, Drew Tortoriello, M.D., an endocrinologist and research scientist at the Naomi Berrie Diabetes Center at Columbia University Medical Center, and his colleagues were curious what effect the herb might have on diabetic mice.

Dr. Tortoriello, working with pediatric resident Stuart Weisberg, M.D., Ph.D., and Rudolph Leibel, M.D., fellow endocrinologist and the co-director of the Naomi Berrie Diabetes Center, discovered that turmeric-treated mice were less susceptible to developing Type 2 diabetes, based on their blood glucose levels, and glucose and insulin tolerance tests. They also discovered that turmeric-fed obese mice showed significantly reduced inflammation in fat tissue and liver compared to controls. They speculate that curcumin, the anti-inflammatory, anti-oxidant ingredient in turmeric, lessens insulin resistance and prevents Type 2 diabetes in these mouse models by dampening the inflammatory response provoked by obesity.

Their findings are the subject of a soon-to-be published paper in Endocrinology and were presented at ENDO 2008, the Endocrine Society's annual meeting in San Francisco this week.

Turmeric (Curcuma longa) has no known dose-limiting toxicities in doses of up to at least 12 grams daily in humans. The researchers tested high-doses of a dietary curcumin in two distinct mouse models of obesity and Type 2 diabetes: high-fat-diet-fed male mice and leptin-deficient obese female mice, with lean wild-type mice that were fed low-fat diets used as controls.

The inflammation associated with obesity was shown several years ago by researchers in the Naomi Berrie Diabetes Center to be due in part to the presence of immune cells called macrophages in fat tissues throughout the body. These cells produce "cytokine" molecules that can cause inflammation in organs such as the heart, and islets of the pancreas, while also increasing insulin resistance in muscle and liver. Researchers hypothesized that by suppressing the number and activity of these cells, with turmeric or a drug with similar actions, it may be possible to reduce some of the adverse consequences of obesity.

Curcumin administration was also associated with a small but significant decline in body weight and fat content, despite level or higher calorie consumption, suggesting that curcumin beneficially influences body composition.

"It's too early to tell whether increasing dietary curcumin [through turmeric] intake in obese people with diabetes will show a similar benefit," Dr. Tortoriello said. "Although the daily intake of curcumin one might have to consume as a primary diabetes treatment is likely impractical, it is entirely possible that lower dosages of curcumin could nicely complement our traditional therapies as a natural and safe treatment."

For now, the conclusion that Dr. Tortoriello and his colleagues have reached is that turmeric – and its active anti-oxidant ingredient, curcumin – reverses many of the inflammatory and metabolic problems associated with obesity and improves blood-sugar control in mouse models of Type 2 diabetes.

In addition to exploring novel methods of curcumin administration to increase its absorption, they are also interested in identifying novel anti-inflammatory processes invoked by curcumin and in adapting those processes in the development of more potent curcumin analogues.

The Health Benefits of Drinking Coffee

Coffee might soon be considered a health drink following a study showing it is a surprisingly rich source of anti-cancer agents.

A study has found that coffee contributes more antioxidants - which have been linked with fighting heart disease and cancer - to the diet than cranberries, apples or tomatoes.

Fruit and vegetables have long been known to be a good source of antioxidants, but the new findings are surprising because it is the first time that coffee has been shown to be such a rich source of the agents.

Professor Joe Vinson of the University of Scranton in Pennsylvania warned, however, that the study did not prove that coffee was good for you because high levels of antioxidants in food did not necessarily translate into higher levels absorbed by the body.

Nevertheless, the research - which was funded by the American Cocoa Research Institute - indicates that at least where coffee is consumed in high amounts, the beverage could be responsible for relatively high levels of antioxidants in the diet.

"Americans get more of their antioxidants from coffee than any other dietary source. Nothing else comes close," said Professor Vinson, whose study was described at the weekend to the American Chemical Society in Washington.

The study found that both caffeinated and decaffeinated coffee appeared to provide similar levels of antioxidants.

The American findings are probably reflected in Britain, where people drink about 70 million cups of coffee each day despite the country's reputation as a tea-drinking nation. More than half of the American population are daily coffee drinkers. Although coffee consumption may be lower in the United Kingdom, nearly half of the British population regularly drinks instant or ground coffee, the market analysts Mintel say.

Antioxidants help to rid the body of harmful free radicals, destructive molecules that damage cells and DNA. They have been linked to a number of health benefits, including protection against heart disease and cancer. Studies have associated coffee drinking with a reduced risk of liver and colon cancer, type two diabetes, and Parkinson's disease.

But Professor Vinson urged moderation, recommending that people should drink only one or two cups of coffee per day. He added that it was important not to ignore the benefits offered by fresh fruit and vegetables. "Unfortunately, consumers are still not eating enough fruits and vegetables, which are better for you from an overall nutritional point of view to their higher content of vitamins, minerals and fibre," he said.

The research showed that, compared with other foods, dates were the richest source of antioxidants. But since so few dates are eaten by Americans, they only contributed a small amount of antioxidants to the average person's diet. Cranberries and red grapes also contain high levels of antioxidants.

A spokesman for the British Coffee Association said: "This study reconfirms the fact that moderate coffee consumption of four to five cups a day not only is perfectly safe but may confer health benefits."

The pros and cons of coffee

BENEFITS
  • Can increase alertness and improve short-term recall.
  • May reduce the risk of cirrhosis of the liver among heavy drinkers.
  • May postpone muscle fatigue.
  • Contains caffeine-related compounds (theophylline) that can alleviate the symptoms of asthma in some cases.
RISKS
  • Increases blood pressure among people who already suffer from high blood pressure.
  • Causes insomnia, anxiety, and irritability.
  • May worsen symptoms of PMS in some women.
  • Can reduce fertility in women trying to conceive.
  • Can cause heartburn and indigestion.

What is Vitamins ?

A vitamin is an organic compound required in tiny amounts for essential metabolic reactions in a living organism. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but that are not essential for life.

Vitamins are bio-molecules that act as catalysts and substrates in chemical reactions. When acting as a catalyst, vitamins are bound to enzymes and are called cofactors. For example, vitamin K is part of the proteases involved in blood clotting. Vitamins also act as coenzymes to carry chemical groups between enzymes. For example, folic acid carries various forms of carbon group – methyl, formyl and methylene - in the cell.

Until the 1900s, vitamins were obtained solely through food intake, and changes in diet (which, for example, could occur during a particular growing season) can alter the types and amounts of vitamins ingested. Vitamins have been produced as commodity chemicals and made widely available as inexpensive pills for several decades, allowing supplementation of the dietary intake.

Macular Degeneration (AMD)

Macular degeneration is a disease of the central retina (called the macula) that affects central vision. It is the leading cause of vision loss among people over age 65.

Because it affects only central vision, macular degeneration does not cause total blindness. But it can make most daily activities like driving and reading difficult or impossible.

What causes it?

The exact cause of macular degeneration is still not understood, but it is thought to be associated with atherosclerotic changes in the tiny blood vessels that nourish the macula, compromising the blood flow to this part of the retina.

Age clearly plays a role in the disease. For this reason, it is often referred to as age-related macular degeneration (AMD).

Macular degeneration has two forms

There are two forms of AMD:
  • Dry AMD is the more common form, affecting approximately 90 percent of those who have macular degeneration. It typically develops slowly and causes mild visual distortion to moderate central vision loss.
  • Wet AMD affects only 10 percent of people with macular degeneration, but causes more severe vision loss. In wet AMD, new blood vessels that form under the macula leak fluid and can cause a rapid and severe loss of central vision.

How common is AMD?

Macular degeneration is the most common cause of severe vision loss among individuals over age 65. It's estimated that over 11 million people in the United States have AMD. It affects about 9 percent of the population over age 40, and causes vision loss of 20/200 or worse (legal blindness) in 15 to 20 percent of those with the condition.

Age is the greatest risk factor. People in their forties have only about a two percent. Those over age 75 have a 30 percent risk.

Other risk factors include:
  • Smoking
  • A family history of AMD
  • High cholesterol
  • A poor ability to tan when young
  • Excessive exposure to sunlight
  • High dietary intake of saturated fat and cholesterol
  • Uncontrolled hypertension
  • A high body mass index in men
  • Race - AMD affects Caucasians more frequently than people of other races
  • Gender - Women are twice as likely to develop AMD
What are the symptoms of AMD?

Macular degeneration is painless. Visual symptoms are constant and limited to the central area of a person's visual field. They include:
  • Distorted vision
  • Blurred vision
  • A central darkened spot or empty area
Can macular degeneration be treated?

Though there is currently no widely accepted treatment for macular degeneration, promising new medications are currently being developed. If you or a family member has AMD, ask your eye doctor about new treatment options that may be available.

Can macular degeneration be prevented?

Recent research suggests certain antioxidant vitamins and other nutritional supplements may slow or prevent the development of macular degeneration in some individuals. Vitamins A, C and E; zinc; Carotenoids; and lutein may be beneficial in maintaining a healthy retina. (These substances, however, have not been shown to reverse existing damage to the retina from AMD.)

Actions you can take to lower your risk of AMD include:
  • Get plenty of exercise
  • Maintain a proper weight
  • Eat a healthy diet
  • Avoiding smoking
  • Take a multiple antioxidant vitamin supplement daily
Because excessive exposure to sunlight is a risk factor for AMD, it's also a good idea to wear sunglasses outdoors that provide 100 percent UV protection. A wide-brimmed hat also helps limit the amount of UV radiation reaching your eyes.

Low vision aids

People who have lost vision due to AMD can often benefit from low vision aids. These specialized optical devices provide high magnification and help a person with AMD use their remaining central vision as effectively as possible.

How to Get Energy from Vitamins

The biggest complaint that doctors often hear from patients is a lack of energy, or the constant feeling of fatigue. Due to these types of complaints, it really isn't a surprise that people want to know the best types of vitamins and supplements they can get for energy. All vitamins are ideal for staying healthy, as well as keeping your body performing in top shape.

Among vitamins and supplements, one of the most common for energy is folic acid. Folic acid is a B vitamin that has been proven to increase energy levels. Even though you can look for vitamins that provide energy, it would be in your best interest to find those that can be effective with fighting fatigue as well. There are vitamins, nutrients, and supplements that are great for fighting fatigue and helping the body stay alert.

The vitamin known as NADH is very powerful for energy, although many people aren't aware of it. People who use vitamins on a regular basis would find themselves very impressed with the boost NADH provides. It is often used with chronic fatigue, although the way it works can be quite complicated indeed. Other vitamins that are great for providing energy include the msm supplement and gingko biloba.

If you happen to be on a blood thinner, such as aspirin, you should always consult with a doctor or other trained specialist before you take gingko biloba, as it is a blood thinning agent. Even though it is considered to be an energy vitamin, if you use it with aspirin it can thin your blood down a bit too much. If you get your blood too thin, it may lead to medical problems later on in life that can prevent you from doing the things you love.

With any vitamin that you take as a source of energy, you should always consult with your doctor. If you have any type of heart or other serious medical condition, you may not be able to take the vitamin you are interested in. For this reason, you should always consult with your doctor and ask for his advice. After a few tests and exams, your doctor will be able to tell you what type of vitamins you should or shouldn't take.

In the world of vitamins and supplements, there are many alternative sources that you can take for energy. Whether you are a senior citizen looking to do more activities or an athlete looking to get more energy, there are many different vitamins out there that can give you what you need. Before you rush out and explore your options though, you should always consult with your doctor first and see if there are any vitamins you shouldn't be taking.

What is Conjunctivitis - Pink Eye?

Conjunctivitis (pink eye) is an irritation of the thin, normally transparent lining (called the conjunctiva) that covers the inner surface of the eyelids and the outer surface of the white of the eye (the sclera). The symptoms of conjunctivitis include redness, itchiness, irritation, and sensitivity to light.Conjunctivitis is commonly called "pink eye" because of the pale red appearance of the infected eye. Pink eye is a common and highly contagious infection among young children.

What causes conjunctivitis?

Allergies, an infection by bacteria or viruses, or by exposure to chemicals or other irritants can cause conjunctivitis.In allergic conjunctivitis, the conjunctiva usually appears swollen and red. The eyes are usually very watery, and itchiness can be severe.If conjunctivitis is caused by bacteria, a sticky, yellow discharge may be present. This discharge may accumulate between the eyelids during sleep, causing the lids stick together.Viral conjunctivitis is usually characterized by redness, itchiness, and a clear, watery discharge.

How common is conjunctivitis?

Conjunctivitis is very common, especially among people with allergies.

How is conjunctivitis treated?

Most types of conjunctivitis are treated with medicated eye drops or ointments. In some cases, oral medicines may also be used.Most types of conjunctivitis are not damaging to the eye or sight threatening. However, conjunctivitis caused by exposure to chemicals is a medical emergency, requiring immediate action to prevent eye damage. If a chemical has gotten in your eye, flush the eye with a gentle stream of cool water for at least 10 minutes. Then cover the eye and go to an urgent care facility or hospital emergency room immediately. Though flushing the eye with water alone may prevent eye damage from some chemical exposures, it is important to have your eye examined as soon as possible by a doctor.

To avoid contracting or spreading conjunctivitis, take the following precautions

  • Wash your hands frequently during the day, especially before and after touching your eyes.
  • Avoid rubbing your eyes.
  • Do not share washcloths, pillows, towels, and make-up items with others.
  • Wash your bedding and towels frequently.
  • If you have a case of bacterial or viral conjunctivitis, discard and replace your current make-up, mascara, and eyeliner.
  • If you wear contact lenses, clean and disinfect your lenses as directed.
  • Wash your hands thoroughly before applying and removing your lenses.
  • Replace your contact lenses frequently.
  • Don't share your contact lenses with others.
  • Wear protective goggles when working with or near chemicals.
  • Avoid swimming in nonchlorinated pools or stagnant lakes or ponds.

How Water Could Possibly Form in the Freezing Darkness of Interstellar Space



Water is the most abundant solid material in space. Astronomers see it on various planets, on moons, in comets and in interstellar clouds. But how did it get there? Nobody really knows how water could possibly form in the freezing darkness of interstellar space.

At least they didn’t until now. Today, Akira Kouchi and buddies at the Institute of Low Temperature Science at Hokkaido University in Japan say that have created water for the first in conditions similar to those found in interstellar space.

Water forms quite easily when oxygen and atomic hydrogen meet. The problem is that there is not enough of it floating around as gas in interstellar dust clouds. So instead, the thinking is that water must form when atomic hydrogen interacts with frozen solid oxygen on the surface of dust grains in these clouds.

Kouchi and co recreated this process by creating a layer of solid oxygen on an aluminum substrate at 10K and then bombarding it with hydrogen. Sure enough, infrared spectroscopy confirmed the presence of water and hydrogen peroxide, and in the right quantities to explain the abundance of water seen in interstellar clouds.

That’s cool and in more ways than one. All the water in the solar system–in comets, on Mars and in the oceans on Earth–must have formed in exactly this way in the interstellar dustcloud which pre-dated Sol and the planets.

So that’s not just any old water you’re sipping, that’s interstellar star juice.

Wha is SIP Trunking ?

Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk allows a company to replace these traditional fixed Public Switched Telephony Network (PSTN) lines with PSTN connectivity via a SIP trunking service.

A SIP Trunk is a logical connection between an IP PBX and a Service Provider’s application servers that allows voice over IP traffic to be exchanged between the two. When a call is placed from an internal phone to an external number, the PBX sends the necessary information to the SIP Trunk provider who establishes the call to the dialed number and acts as an intermediary for the call. All signaling and voice traffic between the PBX and the provider is exchanged using SIP and RTP protocol packets over the IP network.

If the number being called is a traditional PSTN telephone, the trunk provider routes the IP packets to a PSTN Gateway that is closest to the number being called, to minimize possible long distance charges. The provider can also terminate PSTN numbers, and route incoming calls for those numbers back to the IP PBX over the SIP can also Trunk. This allows businesses to offer local phone numbers in several geographical areas, but service them all from a single location.

If the number being called can be reached over a SIP Trunk, the call does not need to be routed over the PSTN, but can be carried on the IP network end to end. Providers can deliver these calls to their customers for very little cost, and many offer them at no charge. Some service providers have agreements and exchange calls for each others customers directly over their IP networks. Where no such agreements are in place, calls are routed over the PSTN, even though both endpoints may ultimately be reachable over a SIP Trunk.

The SIP Trunk can be provided by the Internet Service Provider, or by an independent Internet Telephony Service Provider. In fact, there can be several parties involved, each one providing a different part of the service needed to deliver the end-to-end communication: Internet access, SIP termination, PSTN gateway, etc.

Because a SIP Trunk is not a physical connection, there is no explicit limit on the number of calls that can be carried over a single trunk. Each call consumes a certain amount of network bandwidth, so the number of calls is limited by the amount of bandwidth that can flow between the IP PBX and the provider’s equipment.

World’s largest tidal power project coming to Korea



If there’s one thing we can depend on it’s the rising and falling of the tides. Up until very recently, tidal power has been a severely underutilized renewable energy source, but this won’t be the case much longer with the announcement of the world’s largest tidal power project in South Korea. A collaboration between Lunar Energy and Korean Midland Power Co (KOMIPO), and would create a colossal 300-turbine field in the Wando Hoenggan Water Way off the South Korean coast by 2015, providing 300MW of renewable energy, enough to power 200,000 homes!

World’s Largest Solar Energy Projects

Mojave Desert, Southern California

California not only boasts the highest concentration of hybrid cars in the United States, but it can now also claim the world’s largest solar energy project. Phoenix-based Stirling Energy Systems, working with utilities firm Southern California Edison, is developing an enormous, 4,500-acre thermal solar generating station in southeastern California’s Mojave Desert. The station will initially encompass 20,000 40-foot-tall, dish-shaped mirrors and produce 500 MW of electricity. And the site might expand to 850 MW—making it at least 500 MW more powerful than any of the other large solar plants in the pipeline. Stirling’s dish technology uses mirrors to focus the sun’s rays on the receiver of a device called a Stirling engine. When the hydrogen inside the receiver expands, it creates enough pressure to kick the engine into gear and drive an electricity generator without any need for gasoline or water, and without producing emissions. The company claims its process is nearly twice as efficient as other solar technologies, and Stirling is also planning to construct a 300 MW site in California’s Imperial Valley. Construction of the Mojave Desert facility is due to begin in the middle of this year.

World's Largest Diamond Mine



This diamond mine is located eastern Siberia is so deep that the surrounding "air zone... is closed for helicopters" after "a few accidents when they were 'sucked in' by downward air flow..."

The Largest Diamond Ever Exist

The largest diamond to ever exist was discovered on January 26,1905. It was called the Cullinan Diamond. It was found in the Premier Mine in Pretoria, South Africa. This diamond weighed 3,106.75 carats (621.35 gms). The diamond weighed 1.33 pounds. It was discovered during a routine inspection by the mine superintendent, Mr. Frederick Wells. Fredrick Wells was 18 feet below the earth’s surface, when he spotted a flash of starlight just above him. The diamond was on the wall a few feet above him. He climbed up and got it out. His discovery was presented that same afternoon to Sir Thomas Cullinan who owned the mine. Cullinan then sold the diamond to the Transvaal Provincial Government. The stone was presented to Britain’s King Edward VII as a birthday gift on his sixty-sixth birthday. King Edward VII was worried that the diamond might be secretly stolen in transit from Africa to London. So he set up a decoy, with a phony diamond, aboard a steamship loaded with detectives.

Eventually the Cullinan was divided into 106 polished diamonds. One of the largest stones that was cut from the Cullinan diamond is called Star of Africa I or Cullinan I, and it weighed 530 carats. It is the largest, fine-cut, colorless diamond in the world. The second largest stone cut from Cullinan diamond is called the Star of Africa II or Cullinan II. It is 317 carats. These stones along with the Cullinan III, which is the third largest diamond cut, are displayed, and well guarded, in the Tower of London with other crown jewels from Britain.

Alligator Blood May Be Source of New Antibiotics ?



Despite their reputation for deadly attacks on humans and pets, alligators are wiggling their way toward a new role as potential lifesavers in medicine, biochemists in Louisiana reported today at the 235th national meeting of the American Chemical Society. They described how proteins in gator blood may provide a source of powerful new antibiotics to help fight infections associated with diabetic ulcers, severe burns, and “superbugs” that are resistant to conventional medication.

Their study, described as the first to explore the antimicrobial activity of alligator blood in detail, found a range of other promising uses for the gator’s antibiotic proteins. Among them: combating Candida albicans yeast infections, which are a serious problem in AIDS patients and transplant recipients, who have weakened immune systems, the scientists say.

“We’re very excited about the potential of these alligator blood proteins as both antibacterial and antifungal agents,” says study co-author Mark Merchant, Ph.D., a biochemist at McNeese State University in Lake Charles, La. “There’s a real possibility that you could be treated with an alligator blood product one day.”

Previous studies by Merchant showed that alligators have an unusually strong immune system that is very different from that of humans. Unlike people, alligators can fight microorganisms such as fungi, viruses, and bacteria without having prior exposure to them. Scientists believe that this is an evolutionary adaptation to promote quick wound healing, as alligators are often injured during fierce territorial battles.

In collaboration with Kermit Murray and Lancia Darville, both of Louisiana State University in Baton Rouge, Merchant and colleagues collected blood samples from American alligators. They then isolated disease-fighting white blood cells (leucocytes) and extracted the active proteins from those cells.

In laboratory tests, tiny amounts of these protein extracts killed a wide range of bacteria, including MRSA (methicillin-resistant Staphylococcus aureus), the deadly bacteria that are moving out of health care settings and into the community. These “superbugs” are increasingly resistant to multiple antibiotics and cause thousands of deaths each year.

The proteins also killed six out of eight different strains of Candida albicans, the researchers say. Their previous research also suggests that blood proteins may help fight HIV, the virus that causes AIDS.

The scientists are working to identify the exact chemical structures of the antimicrobial proteins and determine which proteins are most effective at killing different microbes. The gator blood extract may contain at least four promising substances, they estimate.

With the chemical structures in hand, scientists can begin developing them into antibacterial or antifungal drugs, including pills and creams, for fighting infections. These drugs show particular promise as topical ointments, Merchant says. Gator-blood creams could conceivably be rubbed onto the foot ulcers of patients with diabetes to help prevent the type of uncontrolled infections that lead to amputations, he says. The creams could also be applied to the skin of burn patients to keep infections at bay until damaged skin can heal, the researcher adds.

Merchant suggests that the proteins might be called “alligacin.” If studies continue to show promise, the drugs could land on pharmacy shelves in another seven to ten years, he estimates. Until then, don’t try to create your own home-remedies using alligator blood, as raw, unprocessed blood could make you sick or even kill you if injected, the researcher cautions.

Similar antimicrobial substances might also be found in related animals such as crocodiles, Merchant notes. In the future, he plans to study blood samples from alligators and crocodile species throughout the world to test their disease-fighting potential. The state of Louisiana and the National Science Foundation provides funding for this research.

The Largest Animal Alive

The largest animal alive is the blue whale. Fully grown, these great creatures reach a length of over 30 metres and weigh as much as twenty-four large elephants, or more than 1,500 men. The heart of a blue whale is more than a metre in diameter.

The blue whale is not a fish, even though it spends its entire life in the sea. Whales are mammals, just like us. A mother whale gives birth to a live baby whale, not an egg. She feeds her baby with her own milk. While fish are cold-blooded, whales are warm-blooded, and they have lungs and breathe air, like us.

For all its size, a blue whale feeds mainly on this shrimps. It is harmless to man. Unfortunately for the blue whales, men are not harmless to them. So many blue whales have been hunted and killed that very few of these magnificent animals are now left alive.

Blue whales may reach over 24 m (80 ft) in length; mature females are usually slightly longer than mature males. A small dorsal fin is set far back on the body. The skin has a light-gray-and-white mottled pattern, which appears light blue when the whale is just below the surface of the water on a sunny day. The mottled pattern, which is unique to each animal, has been used by researchers to identify individual whales.

Blue whales were heavily hunted for oil, baleen, meat, and other products from the 1930s to the 1960s. This hunting nearly caused the extinction of the species. They are now protected and may gradually be returning in several areas of their range; since 1985, blue whales feeding in Monterey Bay, California, have become a familiar sight in late summer. The blue whale is classified as an endangered species.

World’s Tallest Tree

In Redwood National Park, national park, located in northwestern California, established in 1968. The world’s tallest tree (112 m/367 ft) is located here. The park encompasses a 64-km (40-mi) strip of scenic Pacific coastal territory and contains virgin forests of ancient redwood trees (Sequoia sempervirens). Heavy rainfall has produced a luxuriant vegetation that includes ponderosa pine, Douglas fir, Sitka spruce, and, in places, an underbrush of azalea and rhododendron. The park preserves an undisturbed coastline of bluffs, beaches, rocky inlets, and lagoons. The park’s boundaries were expanded in 1978 and designated a World Heritage Site in 1980. Area, 45,532 hectares (112,512 acres).

Animals Use Pheromones to Communicate, but Do Humans?

Some couples just seem to have a certain chemistry together. Research is showing that they might be exactly right.

Scientists now believe they have found the first human gene associated with the function of pheromones, odorless molecules wafting through the air that signal key survival responses in animals, like dealing with danger or finding a mate.

While rodents and other creatures essentially are reactive animals that depend heavily on pheromones for behavioral cues, it has been a topic of debate whether humans kept any pheromone function along the course of evolution. Humans use their larger brains to rely more on judgment and complex sensory cues, such as vision.

Researchers studying animals have shown how pheromones work, tracing complex neurological paths to stimulate parts of the brain that are deeply rooted in instinct.

Scientists have had their suspicions that humans also use pheromones to communicate with each other chemically. But only recently have experts been able to tease out the parts of the human body that might function this way.

Neurogeneticists at Rockefeller University and Yale say they have isolated a human gene, labeled V1RL1, they believe makes a pheromone receptor, or the chemical's personal reserved parking place. Pheromones would attach to this receptor when they are inhaled into the mucous lining in the nose.

"This is the first convincing identification of a human pheromone receptor," said University of Colorado biochemist Joseph Falke, PhD.

Rodents and other mammals also have the V1RL1 gene, and they rely heavily on pheromone cues to survive. However, it has not been determined whether the gene is active in humans or what sort of activity the gene could trigger.

"The ultimate test will be to find a pheromone that binds to the receptor and triggers a measurable physiological response," Falke said. more info...

Peptic Ulcer Information

1. What is peptic ulcer disease?

Peptic ulcer disease (PUD) is a chronic, recurrent disorder that is characterized by lesions in the upper gastrointestinal tract which appears as reddish and inflamed, or as small depressions or excavations in the upper gastro-intestinal tract. The most common sites of this disease are the duodenum (duodenal ulcer) and the stomach (gastric ulcer). Duodenal ulcer typically affects persons 25-55 years of age while the peak incidence of gastric ulcer occurs around 55-65 years of age.

2. What are the common complaints of patients with peptic ulcer?

The usual complaints are:
  • Epigastric pain or pain in the upper abdomen may be a burning, annoying, or dull in the ache (like hunger pain) that is usually relieved within 5-10 minutes after eating or taking antacids. 50% to 80% of patients reported that they are awakened by pain at night.
  • Nausea, vomiting and a sense of fullness, are fairly common with gastric ulcers but less with duodenal ulcers.
3. How does ulcer develop?
  1. Although acid (from carbonated drinks, juices, alcoholic drinks, etc) may be a major factor for ulcers to develop, other causes are now identified like the presence of Helicobacter pylori and chronic intake of antiarthritic drugs – non-steroidal anti-inflammatory drugs (NSAIDs).
  2. Helicobacter pylori (H, pylori) is a bacteria that colonizes the epithelial cells, lining the surface of the stomach and duodenum where it causes inflammation and ulceration. More than 90% of patients with duodenal ulcers and about 75% with gastric ulcers harbor the organism, which are responsible for frequent relapses of ulcers. Up to 805 of patients with ulcers relapse within 1 year after the initial healing with conventional control of acid secretion (antacids and acid inhibitors). More recent drug regimens include eradication of H, pylori, which has resulted to dramatic reduction of ulcer recurrences.
  3. Other factors include:
  • Smoking
  • doubles the incidence of peptic ulcer disease
  • increases ulcer recurrence
  • reduces ulcer healing with anti-ulcer drugs
  • Genetic influence – first degree relatives of patients with peptic ulcer have 2-3 fold risk of developing the disease
  • Stress – a potent factor in the development of peptic ulcer
4. How do you treat peptic ulcer?

The goals of therapy are to:
  • Promote ulcer healing
  • Relieve pain
  • Prevent complications like bleeding
  • Prevent recurrences
Treatment of peptic ulcer includes the use of:
  1. Antacids – Aluminum and Magnesium hydroxide
  2. Antisecretory Agents
H2-receptor Antagonists – inhibit acid secretion by blocking the H2-receptors in the parietal cells (acid-secreting cells in the stomach).
  • Cimetidine
  • Ranitidine
  • Famotidine
Proton-Pump Inhibitors – the most potent antisecreting agents which almost completely inhibit acid secretion of parietal cells (acid-secreting cells in the stomach).
  • Omeprazole
  • Lansoprazole
  • Pantoprazole
    ----3. Other Agents
    • Sucralfate
    • Bismuth subcitrate
    • Misoprostol
    If you have history of ulcer symptoms, consult your doctor. Do not self-medicate, especially if…
    1. You are more than 40 years of age
    2. You have severe, intractable pain
    3. You have blood in stools
    4. You vomit ground coffee-like substance, and
    5. You have significant weight loss.

    How to Prevent or Delay Diabetes

    Pre-diabetes is a serious medical condition that can be treated. The good news is that the recently completed Diabetes Prevention Program study conclusively showed that people with pre-diabetes can prevent the development of type 2 diabetes by making changes in their diet and increasing their level of physical activity. They may even be able to return their blood glucose levels to the normal range.

    While the DPP also showed that some medications may delay the development of diabetes, diet and exercise worked better. Just 30 minutes a day of moderate physical activity, coupled with a 5-10% reduction in body weight, produced a 58% reduction in diabetes.

    Making Healthy Food Choices

    Knowing what to eat can be confusing. Everywhere you turn, there is news about what is or isn't good for you. Some basic principles have weathered the fad diets, and have stood the test of time. Here are a few tips on making healthful food choices for you and your entire family.
    • Eat lots of vegetables and fruits. Try picking from the rainbow of colors available to maximize variety. Eat non-starchy vegetables such as spinach, carrots, broccoli or green beans with meals.
    • Choose whole grain foods over processed grain products. Try brown rice with your stir fry or whole wheat spaghetti with your favorite pasta sauce.
    • Include dried beans (like kidney or pinto beans) and lentils into your meals.
    • Include fish in your meals 2-3 times a week.
    • Choose lean meats like cuts of beef and pork that end in "loin" such as pork loin and sirloin. Remove the skin from chicken and turkey.
    • Choose non-fat dairy such as skim milk, non-fat yogurt and non-fat cheese.
    • Choose water and calorie-free "diet" drinks instead of regular soda, fruit punch, sweet tea and other sugar-sweetened drinks.
    • Choose liquid oils for cooking instead of solid fats that can be high in saturated and trans fats. Remember that fats are high in calories. If you're trying to lose weight, watch your portion sizes of added fats.
    • Cut back on high calorie snack foods and desserts like chips, cookies, cakes, and full-fat ice cream.
    • Eating too much of even healthful foods can lead to weight gain. Watch your portion sizes.

    5 Tips To Help You Stay Healthy

    The key to a long, happy and prosperous life is, of course, good health. While we may be pre-destined to certain conditions or diseases, there are definitely things we can do to ward off illness and stay healthy for as long as possible. Here are five simple tips that anyone can do to help you live a long life full of good health.

    1. No smoking

    Don’t smoke, and if you do quit immediately. Smoking is perhaps the most preventable and avoidable cause of many debilitating and fatal diseases and conditions. Besides damaging the lungs, smoking also does considerable, irreversible damage to the heart as well as other organs of the body, including even the skin, not to mention the high risk of several types of cancer.

    2. Drink in moderation

    Studies have shown that drinking in moderation, meaning no more than one drink per day, can have a protective effect on the body depending on the type of alcohol consumed. Red wine, Beer for instance, has been shown to have a positive effect on the heart while distilled spirits such as vodkas and bourbons may increase a person’s risk of developing certain cancers.

    3. Eat healthy

    An overwhelming percentage of the population is either overweight or obese. A simple, yet sensible eating plan coupled with regular exercise is the absolute best way to lose weight, keep it off and stay healthy for the rest of your life. There are no “quick fixes” when it comes to good health and diets that are high in fat and cholesterol are linked with diseases such as diabetes and cancer.

    4. Exercise regularly

    After consulting with your doctor the two of you can determine what level of exercise is the best for you. It’s important to remember that more is not necessarily better, particularly if you are just starting to exercise or have had an otherwise sedentary lifestyle. A gradual increase in your work-outs will also increase your level of endurance for the best long-term results.

    Here are some simple exercises that are excellent for losing weight, getting in shape and maintaining good health while strengthening your heart at the same time.
    • Walking: Almost anyone can do it and brisk walking can burn a few hundred calories per hour.
    • Running: While not for beginners, running is an excellent form of cardio exercise as it increases lung capacity, strengthens the heart and burns many calories.

    Role of Vitamin B2

    What Vitamin B2 (or Riboflavin) Does For Your Health

    The second B complex vitamin, B2, is also known as riboflavin. Vitamin B2 is a member of the group of 8 vitamins which make up the nutritional group known as the Vitamin B complex. These B vitamins are essential to the functioning of the body in almost every way, and they play very important roles in all the bodily systems.

    Apart from their major influence on the physical health of the body, the Vitamin B complex is also essential to mental functioning, including cognition and the stability of emotional responses.

    Vitamin B2 has many roles in human health and functioning. This vitamin is a key part of the fundamental workings of human blood. It assists in the production of red blood cells, the means by which oxygen, vital to every cell in the body, is transported through the circulatory system. It is also essential in the production of antibodies and the body’s absorption of iron.

    Additionally, Vitamin B2 aids the digestive system by helping the body to make use of the energy potential in carbohydrates. It serves to protect the health of the mucus membranes, especially those that act within the digestive process to keep the foods consumed moving smoothly through the digestive tract. It is a cofactor, or partner, in the metabolism of amino acids, fatty acids, and certain proteins.

    Because it plays a role in the regulation of the activity of the thyroid, Vitamin B2 is very important to normal growth and development; it is also key to the reproductive system. Vitamin B2 acts as a cofactor to Vitamin B6, which itself could not be active without the Vitamin B2 in the body. This co-operative action takes place in many processes, and also helps in making niacin useful to the body.

    Vitamin B2 also has a role to play in adrenal gland function and tissue repair in the body, while helping to keep the skin, hair, fingernails and toenails healthy. Lastly, it is essential to good vision, and may play a role in the prevention of cataracts.

    Did You Know What is Glaucoma?

    Glaucoma is a group of diseases that can steal sight without warning or symptoms. Over three million Americans have it. Only half know.

    What causes glaucoma?

    The eye constantly produces aqueous, the clear fluid that fills the anterior chamber (the space between the cornea and iris). The aqueous filters out of the anterior chamber through a complex drainage system. The delicate balance between the production and drainage of aqueous determines the eye’s intraocular pressure (IOP). Most people’s IOPs fall between 8 and 21. However, some eyes can tolerate higher pressures than others. That’s why it may be normal for one person to have a higher pressure than another.

    Glaucoma Treatments

    Depending on the severity, treatment can involve glaucoma surgery, lasers, or medication. Eye drops with medication aimed at lowering IOP usually are tried first to control glaucoma.

    Because glaucoma is often painless, people may become careless about strict use of eye drops that can control eye pressure and help prevent permanent eye damage. In fact, non-compliance with a program of prescribed glaucoma medication is a major reason for blindness resulting from glaucoma. >> learn more
