A Novel Neurotrophic Drug for Cognitive Enhancement and Alzheimer's Disease

A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer's disease.  The drug, known as J147 (above  structure), improved memory and prevented brain damage caused by the disease claims the researchers from Salk's Cellular Neurobiology Laboratory, lead by David Schubert. The new compound,  could be tested for treatment of the disease in humans in the near future.Researchers add that, J147 enhances memory in both normal and Alzheimer's mice and also protects the brain from the loss of synaptic connections.

Salk researchers went on to show that it prevented cognitive decline in animals with Alzheimer's and that mice and rats treated with the drug produced more of a protein called brain-derived neurotrophic factor (BDNF), a molecule that protects neurons from toxic insults, helps new neurons grow and connect with other brain cells, and is involved in memory formation.

Because of the broad ability of J147 to protect nerve cells, the researchers believe that it may also be effective for treating other neurological disorders, such as Parkinson's disease, Huntington's disease and amyotrophic lateral sclerosis (ALS), as well as stroke.

Although it is yet unknown whether the compound will prove safe and effective in humans, the Salk researchers' say their results suggest the drug may hold potential for treatment of people with Alzheimer's...

Scientists identify why African naked mole-rat feels no pain when exposed to acid

In continuation of my update  naked mole-rat

Scientists identify why African naked mole-rat feels no pain when exposed to acid: British researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world's most unusual mammals, feels no pain when exposed to acid.

Diabetes drug rosiglitazone can reduce development of neuropathic pain..

In continuation of my update on Rosiglitazone,

The diabetes drug rosiglitazone (Avandia) can control inflammation leading to nerve damage and abnormal pain responses,  claims the researchers of  Juntendo University School of Medicine, Tokyo.

As per the claim by the researchers, Rosiglitazone works by blocking a specific pathway—called PPAR-gamma—which appears to play a critical role in the development of disabling neuropathic pain. Researchers  therefore propose PPAR-gamma regulation of the macrophage-mediated inflammatory response as a novel therapeutic target for treating neuropathic pain development.

When Having the Blues is a Good Thing: Blueberries & Cancer Prevention

In continuation of my up date on the usefulness of blue berries.

Now researchers from the Department of Nutrition Sciences at the University of Alabama at Birmingham, lead by Laura Newton have come up with another interesting finding about blue berries, i.e., as little as a cup a day can help prevent cell damage linked to cancer.

As per the claim by the researchers, free radicals, atoms that contain an odd number of electrons and are highly reactive, can cause cellular damage, one of the factors in the development of cancer; many believe a diet filled with fruits and vegetables may help reduce the risk. 

Lead researcher says
"Studies suggest that antioxidants may help prevent the free-radical damage associated with cancer"

Researchers add that, Blueberries also are rich in vitamin C, which helps the immune system and can help the body to absorb iron. "Vitamin C also helps to keep blood vessels firm, offering protection from bruising. Blueberry juice and other products may be nutritious but often contain less fiber than the whole fruit, and added sugar or corn syrup may decrease their nutritional value. Consuming fresh, raw blueberries provides the most benefits; the average serving size of raw blueberries is one cup, which contains about 80 calories...


Ivabradine also effective in reducing the risk of diastolic heart failure..

Researchers from the Montreal Heart Institute (MHI) have come up with the new findings about the drug,  ivabradine (see structure). Researchers claim that,  a heart rate reduction medication, is also effective in reducing the risk of diastolic heart failure (left ventricular insufficiency) and cardiac fibrosis.

As per the claim by the researchers Ivabradine, reduces Diastolic Dysfunction and Cardiac Fibrosis. The study was conducted on rabbits given a standard diet, a cholesterol-enriched diet or a cholesterol-enriched diet with ivabradine. Researchers found  that apart from improving the myocardial performance index, ivabradine greatly improved left ventricular diastolic dysfunction in animals receiving a cholesterol-enriched diet. Ivabradine also reduced fibrosis of the heart chambers adds the researchers.

According to Dr. Jean-Claude Tardif, Director of the MHI Research Centre and professor of medicine at the Universit- de Montr-al, 

"The effectiveness of ivabradine in treating angina pectoris is now well known. However, few treatments are available to patients with diastolic heart failure. The beneficial effects of ivabradine demonstrated in laboratory suggest that this course of treatment should be further investigated." Clinical studies with subjects are expected to follow..........
