The latest trial of a new heartbeat abnormality drug shows quite promising results in the condition. The drug, called dronedarone, has been tested for atrial fibrillation that is affecting nearly 2.2m Americans.

In atrial fibrillation, the upper heart chamber quivers instead of beating energetically and it can cause blood clots formation to block some brain artery can cause strokes.

In an international trial in which 2,301 patients with the condition were included, the researchers found that dronedarone decreased the number of hospitalization because of heart attack, strokes and other problems nearly 24%. The report of the trial has been published in the New England Journal of Medicine Feb.12 issue.

Dronedrone review status has been assigned by the US Food and Drug Administration and to discuss the possible approval of the drug, FDA advisory committee to meet on March 19.

In these days of worldwide economic gloom, there is a considerable number of people who have become or more prone to become an easy victim of depression. Majority of people seem to believe that it’s only economy and financial wellbeing on which their welfare depends and when they have to suffer some loss in terms of financial aspects of life, they get depressed. The sad fact is that many don’t even know that they have become a victim of depression, as they don’t have sufficient knowledge about its symptoms. Those who know that they have become a victim of it always look for some better treatment options and medication. The market is replete with anti-depressant drugs, however, when it comes to winning people’s trust, Lexapro and Effexor are two names in which people seem to trust. There are many people who want to know where they can buy generic lexapro or want to know about a better source to buy generic Effexor.

A new study in Washington shows that women cannot suppress their hunger as efficiently as men can. This study was conducted by Gene – Jack Wang of national Laboratory with his colleagues.

To conduct the study, a group of 10 men and 13 women was taken. The purpose of the study was aimed to find out the reasons of over eating and weight gain. Researchers also worked to try and understand human brain mechanism while controlling appetite. They specifically checked the difference between varying brain functions of men and women.

The group used for study was made to fast a night prior, so that brain response can be determined at the sight of food of their choices. The participants’ brains were scanned to see the changes. They were also trained for cognitive inhibition; suppression of thoughts of appetite.

Whether it’s Midwest or Northeast, much of the United States has turned into a deep freezer because of the intense cold.  National weather Service says that the country would remain in the clutches of intense cold for next many days.

When there is below 20F with 20m/h wind, an exposed skin takes only few minutes to be frostbitten, but sometimes you have to go in this extreme cold willingly or unwillingly. The following recommendations can help you a lot to keep yourself and dear ones safe and protected in these extreme cold.

When the inner body temperature falls below 95 degree, Hypothermia begins to set in and can affect your brain. Often, the victim of this condition can’t think clearly and begins to lose coordination. Hands, tip of the nose, fingers, feet and toes can badly are quite susceptible to extreme cold.  The different tissues of the body begin to freeze because of the frostbite that causes ice crystals which harm the cells.

Elderly and kids can become an easy victim of frostbite and hypothermia, and similarly those people who have blood circulation problems like diabetes or use various drugs like nicotine, alcohol and beta blockers are also at higher risk for hypothermia or frostbite. The use of thee types of drugs become the cause of insufficient blood supply to the skin.

The results of a new study show that decrease in blood flow, blood pressure as well as repeated surges in sleep apnea patients’ brains may become the cause of strokes or death during sleep.

Researchers from the Yale University School of Medicine find that sleep apnea becomes the cause of dropped blood flow in the brain while in episodes. When it takes place, the blood pressure of the organ begins to rise and when this happens again and again the ability of the brain to guard itself in these conditions begin to reduce.

A previous study from the Yale researchers suggests that sleep apnea patients have three times higher risk of having a stroke or death during sleep than the people who don’t suffer from this disorder.

Currently, nearly 18m people in the US are suffering from sleep apnea that is a sleeping disorder in which breathing gets hampered or ceased because of the upper airway blockage. It becomes the cause of low blood oxygen levels and rise in blood pressure. However, when the patient briefly awakens, the order restores again.

Too much consumption of fructose, a type of carbohydrates, found in snacks, cookies, candies, soda etc, can block the action of leptin hormone which signals to the brain that the body has had enough to eat and enhance the risk of obesity, a University of Florida study of rats suggests.

Obesity has already been associated with leptin resistance, a long ago and multiple studies have expressed that, excessive use of fructose may be a significant factor in the U.S. obesity epidemic. This fresh study is the first one, relating fructose with leptin resistance.

The researchers experienced that, rats became leptin-resistant after six months with constant high fructose diet given to them. There were no sign which could express that leptin resistance was occurring, but the fructose-fed rats gained much more weight than rats that fed on fructose free diet, when both groups of rats were switched to a high-fat diet.

Overview

Most users agree Salvia divinorum is quite unique, and some find its effects unsettling. Its active principle, Salvinorin A, is structurally unique among psychoactive drugs, and receptor binding studies have revealed nothing, which could indicate a previously unknown pathway in the brain.

Salvia divinorum is an extraordinary visionary herb. It is not a recreational drug. It produces a profoundly introspective state of awareness that is useful for meditation, contemplation, and self-reflection.

Its effects are unique and cannot be compared with the effects of other drugs. The effects of Salvia do not appeal to many people. The people who are most drawn to it are both mature and philosophically minded. Beware of inaccurate information. There are many unethical vendors who try to lure naive customers by portraying the effects of Salvia as more appealing than they are.

The news media often sensationalizes stories about Salvia, exaggerating its effects, risks, and popularity. Much of what has appeared in the popular press is inaccurate and misleading. Salvia is not “legal pot.” It is not “legal acid.” It is not a substitute for any other drug. Before trying Salvia, it is important that you know about its effects, appropriate uses, and the potential risks associated with irresponsible use of this drug.

The way AIDS virus brings itself back to life after the use of powerful drugs wasn’t less than a mystery for medical researchers.

But now a new study says that HIV can lie dormant inside some cells (it can be even a single cell) until emerging again to cause destruction.

Huldrych Gunthard, a researcher at University Hospital Zurich, in Switzerland, who is co-author of the study says that their findings are indeed good news, as they suggest that virus doesn’t replicate itself when dormant.

Such drugs are available in the market since the mid-1990s that allow many AIDS patients to decrease the level of the virus in their blood to zero, but the disease remains incurable. Gunthard says that the virus can hide itself in the lymphatic system, bone marrow, brain and in other places in the body.

According to an American study, Alzheimer’s patients can be effectively treated by controlling a fatty acid level in the brain.

The researchers made some tests on mice and found that higher levels of the acid caused memory problems and behavioral changes in the brain.

A report in Nature Neuroscience says that fatty acid levels can be controlled via diet or drugs.

According to a UK Alzheimer’s expert, “the work is quite exciting and robust.”

In UK, there are more than 700,000 patients with dementia and some forecasts suggest that the number would be double within a generation.

In their study, the researchers from Gladstone Institute of Neurological Disease and the University of California examined fatty acids level in the brains of normal mice and compared them with genetically engineered mice with Alzheimer’s-like condition.

A new research finds that an extract from the ginkgo tree can reduce or avoid brain damage from a stroke in genetically engineered mice.

According to the study author Sylvain Dore, the activity of free radicals that attack and kill cells can be neutralized with the help of this ginkgo extract.

“It’s quite interesting as we are examining a mechanism of action that has not been anticipated before,” Dore said.

The findings will be published in the Oct.10 issue of the journal Stroke.

There was a quick skeptical response on this report from Dr. Larry B. Goldstein, who is director of the Duke University Stroke Center.
