First 3-D structure from key influenza protein revealed

In 1918, 50 million people died during a worldwide influenza pandemic caused by mutation of a bird-specific strain of the influenza virus. Recently H5N1, another highly infectious avian strain has caused outbreaks of bird flu around the world.

Gene therapy shows promise as treatment for diseased lower limbs at risk for amputation

New research suggests that gene therapy is a safe treatment method to explore in patients whose lower limbs are at risk for amputation because of poor circulation caused by blocked blood vessels.

Genetically caused deafness may be reversible by compensating for a missing protein

Emory University researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30.

Diet rich in black soya beans could help control weight, lower fat and cholesterol levels

Yellow soya has already been hailed for its cholesterol lowering capabilities; this is one of the reasons why frozen food manufacturer Birds Eye has added the beans to its range. However, a team of Korean researchers has shown that black soya may be even more potent in rats, and also prevents weight gain.

Old drug pentylenetetrazole may improve learning and memory in Down syndrome victims

Researchers in the United States have discovered that an old drug once used to study epilepsy substantially improved learning and memory in mice with Down syndrome symptoms.

Caffeine offers seniors protection against heart disease

According to researchers in the United States seniors who are regular drinkers of caffeinated beverages have a lower risk of coronary vascular disease and heart attacks.

Irregular heartbeat linked to genetic mutation

Every day for 10 years, a seemingly heart-healthy 53-year-old woman experienced rapid and irregular heartbeats. She had no personal or family history of hypertension or hyperthyroidism. She did not suffer from myocardial or coronary artery disease, or any abnormalities of the heart as best doctors and medical science could determine.

Alternative, diet-based method of treating brain cancer

The biologists found that KetoCal, a commercially available high-fat, low-carbohydrate diet designed to treat epilepsy in children, can significantly decrease the growth of brain tumors in laboratory mice.

microRNA directly regulates a gene implicated in human cancers

MicroRNAs are tiny snippets of RNA that can repress activity of a gene by targeting the gene's messenger RNA (which copies DNA information and starts the process of protein production).

Research defines the cancer role for protein Gab-2

A protein known for its ability to "bridge" interactions between other cellular proteins may spur metastasis in breast cancer, the disease's deadliest stage, a study from Burnham Institute for Medical Research has found.

Apolipoprotein C1 protein linked to elevated BMI in people of American Indian and Mexican ancestry

University of Minnesota researchers have discovered a variant of a common blood protein, apolipoprotein C1, in people of American Indian and Mexican ancestry that is linked to elevated body mass index (BMI), obesity and Type 2 diabetes.

microRNAs undergo molecular editing with significant physiological consequences

Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the cellular machinery that uses that information to create proteins, the building blocks of the body.

New understanding of how and why Taxol works in patients with breast cancer

Cancer researchers at Georgetown University Medical Center have taken a step towards understanding how and why a widely used chemotherapy drug works in patients with breast cancer.

Abnormalities in eye movements and attention define risk for schizophrenia

A Binghamton University researcher has established a new framework to help determine whether individuals might be at risk for schizophrenia.

How stem cells are regulated

Researchers from Biotech Research & Innovation Centre (BRIC) at University of Copenhagen have identified a new group of proteins that regulate the function of stem cells. The results are published in the new issue of Cell.

First embryonic stem cell research grants approved under California Proposition 71

The California Institute for Regenerative Medicine's Independent Citizens' Oversight Committee on Friday announced the approval of the first human embryonic stem cell research grants provided under Proposition 71, the San Francisco Chronicle reports.

Pregnancy hormone prolactin gives hope to MS victims

Canadian scientists believe they may be some way to solving the mystery of why women suffering from multiple sclerosis (MS) go into remission while they are pregnant.

Scientists find new genes linked to Lou Gehrig's disease

In the first genome-wide search for the genetic roots of the most common form of amyotrophic lateral sclerosis (ALS), Johns Hopkins scientists have newly identified 34 unique variations in the human genetic code among 276 unrelated subjects with ALS.

Don't advertise during sexy programmes - the viewer won't remember

People are less able to recall the brand of products advertised during programmes with a lot of sexual content, than if the advert is placed in similar programme that has no sexual content.

New test identifies suitable lymphoma patients likely to respond to new therapy

Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered a genetic signature identifying cases of lymphoma that are uniquely susceptible to a newly developed molecular targeted therapy. As a result, physicians organizing clinical trials of the new therapy will be able to enroll patients who'll be most likely to benefit from it.
