Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Beneficial effects of Alpha-Linolenic acid in walnuts

The recently-announced USDA dietary guidelines stress the need for consumers to be more aware of the benefits of polyunsaturated essential omega-3 fatty acids in order to achieve a healthy diet. Many people look to fish, such as salmon, for omega-3s, but plant sources such as walnuts are also specifically noted in the USDA recommendations.

Timing is everything when it comes to killing prostate cancer cells

"The window of opportunity is narrow for vaccination, designed to reinvigorate the immune system's attack on cancer cells, and it occurs right after hormonal therapy begins to wipe out the tumor and immune cells outnumber cancerous ones," according to Charles Drake, M.D., Ph.D.

Neuronal death and processing of Tau protein in Alzheimer’s Disease (AD)

In a research report recently published in the Journal of Alzheimer's Disease, published by IOS Press, a research group from the International School for Advanced Studies (ISAS\SISSA) in Trieste (Luisa Fasulo, Gabriele Ugolini e Antonino Cattaneo) showed that a processed form of tau protein induces neuronal death by apoptosis (programmed cell death) when expressed in cultured rat hippocampal neurons.

Process behind cellular export of iron may help to explain human hemochromatosis

The first direct evidence that a single protein is critical in the cellular export of iron may help to explain human hemochromatosis, researchers report in the March issue of Cell Metabolism.

Bevacizumab (Avastin) in combination with standard chemotherapy helps advanced lung cancer sufferers

Preliminary results from a large, randomized clinical trial for patients with previously untreated advanced non-squamous, non-small cell lung cancer show that those patients who received bevacizumab (AvastinTM) in combination with standard chemotherapy lived longer than patients who received the same chemotherapy without bevacizumab.

Hungry men don't need outsized portions

Remember when advertisers asked, "How do you handle a hungry man?" and offered bigger, man-sized versions of the ever-popular TV dinner?

New insight into key mechanism by which cells limit cholesterol

The finding suggests a novel approach to the development of cholesterol-lowering drugs that may boost the effect of statins, one of the most prescribed cholesterol inhibitors, according to researchers at the University of Texas Southwestern Medical Center.

Heart disease risk in older women identified by simple blood test

Postmenopausal women who are not identified by traditional cardiovascular risk factors, could benefit from a simple blood test to show their white blood cell (WBC) count which may predict cardiovascular events and risk of death.

Gene therapy helps Lou Gehrig's disease

The most common form of motor neurone disease, called amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease, is caused when neurones in the spinal cord die, leading to muscle wasting and total paralysis.

Simple blood test may help to predict cardiovascular risk in older women

White blood cell (WBC) count may predict cardiovascular events and risk of death in postmenopausal women who are not currently identified by traditional cardiovascular risk factors, according to an article in the March 14 issue of Archives of Internal Medicine.

New study regarding Atkins nutritional approach and obese patients

A new study by Temple University School of Medicine researchers has shown why the pounds melt so quickly on low-carbohydrate diets, and it's not related to water, metabolism or boredom. The research was conducted in a group of obese patients with type 2 diabetes who followed the Atkins diet.

You can no longer make the argument that transplanting a kidney into an older recipient is a wasted organ

Growing evidence suggests that age alone shouldn't prevent older adults from being organ donors – or having a kidney transplant themselves – according to researchers at Wake Forest University Baptist Medical Center.

Link between cardiovascular disease and periodontal bacteria

Researchers report this week that older adults who have higher proportions of four periodontal-disease-causing bacteria inhabiting their mouths also tend to have thicker carotid arteries, a strong predictor of stroke and heart attack.

Gene identified that confers susceptibility to age-related macular degeneration

By combining the tools of high-throughput biology and statistical genetics, scientists at Rockefeller University, Yale University School of Public Health and the National Eye Institute have identified a gene that confers susceptibility to age-related macular degeneration (AMD), the most common cause of vision loss in the United Sates for those over 60.

Naturally occurring antifungal agent in saliva kills oral pathogen responsible for most HIV-related oral infections

Oral biologists at the University at Buffalo have shown for the first time how histatin, the naturally occurring antifungal agent in saliva, kills the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections.

Research could lead to new drugs that combat HIV infection by shutting down the virus's assembly lines

After infecting a susceptible cell, the human immunodeficiency virus hijacks that cell's normal machinery to produce carbon copies of itself. New HIV particles roll off the cellular assembly lines, burst like bubbles out of the cell, and float off to invade other cellular factories.

New way of looking at MicroRNA and how it controls gene expression

A group of scientists at The Scripps Research Institute is reporting a discovery that sheds light on an area of research fundamental to everything from the normal processes that govern the everyday life of human cells to the aberrant mechanisms that underlie many diseases, including cancer and septic shock.

RNA interference as promising therapy for ALS

Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have used RNA interference in transgenic mice to silence a mutated gene that causes inherited cases of amytrophic lateral sclerosis (ALS), substantially delaying both the onset and the progression rate of the fatal motor neuron disease.

Gene for AMD has now been identified by researchers

Age-related macular degeneration (AMD) is a debilitating eye disease affecting about 15 million people in the United States.

Active brains stave off Alzheimer's signs

Mice who keep busy playing with toys also keep their brains and bodies active; more importantly, they also have lower levels of the peptides and brain plaques associated with Alzheimer's disease, compared to mice raised in environments not "enriched" with chew toys, running wheels,and tunnels, according to a new study in the 11 March issue of the journal Cell.
