New insights into immune exhaustion

A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out.

Clues about how blood forms could yield new strategies for treating blood diseases

Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood.

Promising new targets for medications to treat cocaine addiction

Repeated use of addictive drugs such as cocaine causes long-lasting changes in parts of the brain involved in motivation and reward, among others, yet the precise mechanisms by which these changes are maintained are poorly understood.

Non-wovens as scaffolds for artificial tissue

When someone's knee hurts with every step it's a sign that the cartilage has been so badly damaged that the bones rub together when walking.

Diet rich in nuts and olive oil protects against age-related macular degeneration

New research has found that a diet which is low in trans fats and regularly includes nuts, olive oil and other foods containing omega-three fatty acids appears to offer some protection from the eye disease age-related macular degeneration (AMD).

IRIN/Plus News examines HIV/AIDS services in Zimbabwe following economic crisis

IRIN/Plus News on Monday examined services for people living with HIV/AIDS in Zimbabwe following an economic crisis in the country.

Research suggests potential new treatment for anxiety disorders and depression

New research on a brain chemical involved in development sheds light on why some individuals may be predisposed to anxiety. It also strengthens understanding of cellular processes that may be common to anxiety and depression, and suggests how lifestyle changes may help overcome both

New understanding of role ZBP1 gene plays in breast cancer

Scientists at Albert Einstein College of Medicine of Yeshiva University have discovered how a gene crucial in triggering the spread of breast cancer is turned on and off. The findings could help predict whether breast tumors will metastasize and also reveal potential drug targets for preventing metastasis.

Pioneering technique for treatment of liver tumours

Leicester consultant surgeon who has developed a pioneering technique using microwaves to destroy liver tumours has treated more than 100 patients in the UK and other patients are now being treated internationally.

Sanofi-aventis to acquire Oforta, oral chronic lymphocytic leukemia treatment

Sanofi-aventis U.S. announced today that it has acquired from biotechnology company Antisoma plc the U.S. commercial rights to Oforta (fludarabine phosphate film-coated tablets), an oral B-cell chronic lymphocytic leukemia (CLL) drug. Oforta is currently approved in the United States for use as a second-line therapy to treat adults with B-cell CLL.

Oxidation of potassium channel in cells linked to loss of neuronal function in aging

Researchers at UMDNJ-Robert Wood Johnson Medical School are one step closer to determining how human cells can be protected against the affects of age-related neurodegeneration including Alzheimer's and Parkinson's disease.

Omega-three fatty acid rich foods lower risk for eye disease

Regularly eating fish, nuts, olive oil and other foods containing omega-three fatty acids and avoiding trans fats appears to be associated with a lower risk for the eye disease age-related macular degeneration, according to two reports in the May issue of Archives of Ophthalmology.

Discovery of genetic cause of luminal-type tumors

The discovery of tumor-suppressor genes has been key to unlocking the molecular and cellular mechanisms leading to uncontrolled cell proliferation - the hallmark of cancer. Often, these genes will work in concert with others in a complex biochemical system that keeps our cells growing and dividing, disease free.

Smoking makes it harder for brain blood flow to recover from long-term heavy drinking

Alcohol-use disorders (AUDs) can damage the brain, particularly the frontal and parietal cortices, although this damage is at least partially reversible with sustained abstinence from alcohol. Chronic smoking is extremely common among individuals with AUDs.

New genetic clues to treatment of hypertension

An international research team has identified a number of unsuspected genetic variants associated with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension (high blood pressure), suggesting potential avenues of investigation for the prevention or treatment of hypertension.

Building a bridge from Alzheimer's disease to diabetes and vice versa

Modern societies face the increasing burden of age-related diseases, in particular Alzheimer's disease (AD) and type 2 diabetes (T2D).

Closer to an effective treatment for gum disease in smokers

Scientists in the USA have discovered why smokers may be more prone to chronic gum disease (periodontitis). One of the bacteria responsible for this infection responds to cigarette smoke - changing its properties and the way it infects a smokers mouth.

Discovery of major new treatment target in diseased arteries

Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA).
