New blood pressure-lowering drugs reduce stroke risk by 50%

According to researchers the new types of blood pressure-lowering drugs are more effective in preventing strokes and heart attacks and save even more lives.

Researchers to test whether cannabinoids can help chronic obstructive pulmonary disease patients

Researchers from Imperial College London are looking for volunteers to test whether cannabinoids, the active ingredient of cannabis, can be used to alleviate the sensation of breathlessness caused by illnesses such as chronic obstructive pulmonary disease (COPD).

Rett Syndrome gene discovery

Adrian Bird of the University of Edinburgh and colleagues report in the online issue of Molecular Cell that the "Rett Syndrome protein", MeCP2, only binds to genes with a specific sequence of nucleotide bases. This knowledge will aid in the identification of the genes that are regulated by the gene MECP2

Medication before angiograph significantly reduces risk of heart attack

According to new research if patients are given the a drug which reduces platelet activity in the blood risk of heart attack and cardiovascular death before and after angioplasty is reduced.

Macrophages kill bacteria - but not always

Macrophages are effective weapons used by our immune system to absorb and digest pathogenic intruders. Some bacteria, however, can subvert this defence mechanism and even multiply within the macrophages.

Chicken pox vaccine associated with shingles epidemic

New research published in the International Journal of Toxicology (IJT) by Gary S. Goldman, Ph.D., reveals high rates of shingles (herpes zoster) in Americans since the government's 1995 recommendation that all children receive chicken pox vaccine.

One protein hardens enamel while the other weakens it, say USC researchers

A gene critical to tooth formation expresses a protein that is then cleaved into two proteins with seemingly opposite functions, according to a University of Southern California (USC)-led team of dental researchers.

Been there, done that!

One of the neural oddities of "declarative" memory--the recall of past things and events--is that some experiments have shown that recognizing a familiar object is accompanied by a reduction in activity of the brain's memory centers in the medial temporal lobe. Such a reduction seems counterintuitive, since remembering seems to be a positive event.

Scientists demonstrate power of new generalized screen to find function of noncoding RNAs

A team of investigators at The Scripps Research Institute and the Genomics Institute of the Novartis Research Foundation (GNF) have discovered a way to screen hundreds and potentially thousands of "noncoding" RNA molecules to discover their functions within cells.

C. elegans worm provides clues to dealing with human disease

A step towards understanding cell mutations that cause a variety of human diseases, particularly in children -- including that which brings about premature aging and early death -- has been taken by researchers at the Hebrew University of Jerusalem Silberman Institute of Life Sciences and the John Hopkins University School of Medicine.

Significant advance in the study of small ribonucleic acids

Scientists from the University of Delaware have made a significant advance in the study of small ribonucleic acids (RNAs), discovering 10 times more small RNAs in the plant Arabidopsis than previously had been identified. The advance is reported in the Sept. 2 issue of Science magazine.

Researchers link individual preferences to neuronal activity in brain

Life is full of choices. But how do individuals know what their preferences are and how do they act on them? And what leads mothers to make choices that benefit or lead to neglect of her offspring? Based on research performed using laboratory rats, a team of neuroscience researchers at Rutgers University-Newark suggest that an intricate system exists within the brain for establishing individual preferences, which ultimately impacts choices.

Tools for studying the chemistry of the brain, neuron by neuron

The human brain is composed of billions of cells, each a separate entity that communicates with others. The chemical interaction of those cells determines personality, controls behavior and encodes memory; but much remains to be understood.

Prostate cancer manipulates an important group of signaling proteins called Wnts to establish itself in bone

Prostate cancer is a cruel disease. Left untreated, prostate cancer cells often metastasize, or spread, to bone where they form fracture-prone tumors that are extremely painful.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."

James Bond affects the development of breasts!

Breakthrough Breast Cancer has announced that UK scientists have discovered that a gene - named after the James Bond villain Scaramanga - can trigger the development of breasts. This has important implications for breast cancer, as reported in the journal Genes and Development.

Men with breast cancer gene at risk of pancreatic and prostate cancers

The very same genetic mutation which has been previously linked to the development of breast cancer in women may also be responsible for some cancers in men.

Mutation in the BRAC2 breast cancer gene may also increase the risk of bone and throat cancers

A genetic mutation implicated in an increased risk of breast and ovarian cancers also significantly increases the risk of pancreatic and prostate cancers in men, finds research in the Journal of Medical Genetics.

Compound called GRN163L blocks lung cancer

Researchers at UT Southwestern Medical Center have found a compound that shows promise as a way to block the spread, or metastasis, of lung cancer.

More than 15 percent of our genes are mobilized to defend against microbial attacks

The body's overwhelming genetic defense, which has implications for the survival of patients who are severely burned or injured, was revealed in a sweeping analysis of gene activity in volunteers who were injected with a bacterial product that temporarily created flu-like symptoms.
