Design of wide-spectrum inhibitors targeting coronavirus main proteases

Coronaviruses - the family of viruses that causes the common cold - gained widespread recognition when the deadly severe acute respiratory syndrome, familiarly known as SARS, killed at least 800 people in 2003.

Genetic hot spots double the risk of early heart disease

According to researchers in the UK there are six genetic "hotspots" that can double the risk of developing early heart disease.

Double whammy of vitamin D and anti-inflammatory zaps prostate cancer cells

Scientists from Stanford University say they have discovered that vitamin D, known as the "sunshine vitamin,"can limit the growth of prostate cancer cells when combined with non-steroidal anti-inflammatory drugs.

New way to assess risk of breast cancer recurrence

Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast.

Human tissue grown from stem cells, available for transplant in the next four years

A team of researchers from the University of Liverpool in the UK have embarked on an ambitious project which could see human tissue grown from stem cells, available for transplant in the next four years.

Gene B-myb essential in preventing tumors

A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors.

Vitamin B may do more harm than good in heart attack patients

Researchers from Norway have found that treating patients who have had a heart attack with high doses of B vitamins does not lower the risk of getting another heart attack or stroke. Contrary to expectations, B vitamins may do more harm than good.

Use of the antiplatelet drug clopidogrel before a coronary angioplasty reduces risk of cardiovascular death

Use of the antiplatelet drug clopidogrel before a coronary angioplasty reduced the risk of cardiovascular death, heart attack or stroke within 30 days following the procedure, according to an article in the September 14 issue of JAMA: The Journal of the American Medical Association.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Researchers discover one of the reasons why melanoma is so ruthless

About 60,000 Americans will be diagnosed with melanoma this year, says the American Cancer Society, and 10,000 of those cases will be fatal. If not caught in the early stages, melanoma can be a particularly virulent form of cancer, spreading through the body with an efficiency that few tumors possess.

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.
