Inflammation in colon may get doused before fueling cancer development

A tiny molecule found in most plant-based foods douses the flames before damaging lesions can form in the colon, according to a study by Texas AgriLife Research scientist Dr. Nancy Turner.

Component of DNA stimulates and suppresses the immune response

A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say.

Statins may treat cerebral cavernous malformation

In a finding that could save thousands of lives a year, University of Utah School of Medicine researchers have shown that a blood vessel disorder leading to unpredictable, sometimes fatal, hemorrhagic strokes, seizures, paralysis or other problems is treatable with the same statin drugs that millions of people take to control high cholesterol.

The drug treatment of heart failure is influenced by the gender of the patient and of the physician

While the treatment of heart failure has improved over the past two decades, a new study reported in the European Journal of Heart Failure finds that "the use of evidence-based treatments appears to be imbalanced according to the gender of the patient".

Researchers create precise biosensor for detecting blood glucose

Researchers have created a precise biosensor for detecting blood glucose and potentially many other biological molecules by using hollow structures called single-wall carbon nanotubes anchored to gold-coated "nanocubes."

First '3D movie' of tumour protein gives new drug hope

First '3D movie' of tumour protein gives new drug hope CANCER RESEARCH UK scientists have created the first complete model of a molecule which captains a key cell signalling network to prevent cancer - and exposed the secret of how a highly selective drug can intervene to control its activity, according to a study published in PLoS Biology.

Potential new target in the war on HIV/AIDS

The study revealed that a variant of a protein involved in HIV pathogenesis can suppress production of an HIV protein, known as Nef. Nef is required for the human immunodeficiency virus to develop into AIDS through a series of complex events involving viral elements and cellular proteins. Nef has never been a target for drug treatment in HIV patients.

Researchers identify biochemical switch required for nerve cells to respond to DNA damage

The finding, scheduled for advance online publication in Nature Cell Biology, illuminates a connection between proteins involved in neurodegenerative disease and in cells' response to DNA damage.

Less severe first heart attacks linked to decline in coronary heart disease deaths

The severity of first heart attacks has dropped significantly in the United States - propelling a decline in coronary heart disease deaths, researchers reported in Circulation: Journal of the American Heart Association.

MRSA's weak point visualised by scientists

An enzyme that lives in Methicillin-resistant Staphylococcus aureus (MRSA) and helps the dangerous bacterium to grow and spread infection through the human body has been visualised for the first time, according to a study out today in Proceedings of the National Academy of Sciences (PNAS).

Researchers find novel use for old compound in cancer treatment

The compound, alpha-difluoromethylornithine or DFMO, targets the activity of a specific enzyme and, even in very limited doses, is effective in protecting against the malignancy in animal models.

How the sensory organs of bacteria function

Bacteria can occur almost anywhere on earth and exist under the most varying conditions. If these tiny, microscopic organisms are to survive in these environments, they need to be able to rapidly detect changes in their surroundings and react to them.

E. coli persists against antibiotics through HipA-induced dormancy

Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science.

Study shows how defective DNA repair triggers 2 neurological diseases

Scientists at St. Jude Children's Research Hospital have teased apart the biological details distinguishing two related neurological diseases-ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS).
