Hidden thousands devastated by myalgic encephalomyelitis

New research published by the UK's leading Myalgic Encephalomyelitis (M.E.) charity, Action for M.E., suggests that a hidden 55,000 people in Britain are so severely affected by the illness that they're either bed-bound or house-bound.

Interferon-gamma plays a critical role in damaging the cells that produce myelin

A new way to preserve the cells that surround and protect nerves could lead to new treatments for demyelinating diseases such a multiple sclerosis, a research team reports in the May 10, 2006, issue of the Journal of Neuroscience.

Space technology to help hospitals contain spread of avian flu infection

In response to concerns from hospitals to prepare for eventual pandemic flu outbreaks, the French company AirInSpace, with support from ESA's Technology Transfer Programme, has successfully adapted technology developed to protect astronauts for use in critical care centres to protect immune-deficient patients against airborne pathogens such as the avian flu virus.

An evolutionary life-history framework for understanding sex differences in human mortality rates

Despite research efforts to find modern factors that would explain the different life expectancies of men and women, the gap is actually ancient and universal, according to University of Michigan researchers.

Aggressive cancer treated successfully in mice

White blood cells from a strain of cancer-resistant mice cured advanced cancers in ordinary laboratory mice, researchers at Wake Forest University School of Medicine reported.

Social stress prompts hamsters to overeat

Put a mouse or a rat under stress and what does it do? It stops eating. Humans should be so lucky. When people suffer nontraumatic stress they often head for the refrigerator, producing unhealthy extra pounds.

Renewed interest in studying influenza A viruses

The emergence of the avian influenza virus H5N1 that is currently devastating chicken flocks in many countries and threatening to unleash a worldwide epidemic among humans has triggered a renewed interest among scientists in studying influenza A viruses, according to investigators at St. Jude Children's Research Hospital.

Effective gene suppression using small interfering RNA in hard-to-transfect human T cells

A technical advance in laboratory techniques may provide biology researchers broader access to RNA interference, a process of blocking the activity of targeted genes. RNA interference has recently emerged as an important tool in studying how genes function in normal biological processes and in disease.

Discovery of new type of cell that generates crucial immune system cells

A new type of cell that generates crucial cells of the immune system has been discovered at The Walter and Eliza Hall Institute.

Calorie counting may lessen the effects of aging

A lifelong habit of trimming just a few calories from the daily diet can do more than slim the waistline - a new study shows it may help lessen the effects of aging.

Bacterial binding in the stomach

Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.

Therapeutic gene suspected to cause cancer

One of the few gene therapy studies that had ever been successful was terminated in 2003, because several of the treated children had developed leukemia.

DARPA grant supports research toward realizing tissue regeneration

While U.S. soldiers fighting in Iraq and Afghanistan are surviving injuries that in previous conflicts likely would have been fatal, the number of wounded with major tissue loss has never before been so high.

Differential effects of HOXB4 on nonhuman primate short and long-term repopulating cells

Transplantation of hematopoietic stem cells (HSCs, the cells that can give rise to all blood and most immune cell types) can save patients whose own hematopoietic system is defective or has been destroyed (often through radiation or chemotherapy of cancer).

Inflammation markers identify fatigue in breast cancer survivors

Researchers at the University of California, Los Angeles have defined conditions associated with disabling fatigue that persists for years in almost a third of breast cancer survivors, according to a study in the May 1 issue of Clinical Cancer Research.

Progressive histological damage in liver allografts following pediatric liver transplantation

A new study on the long-term outcome of children undergoing liver transplants found that chronic hepatitis (CH) was common and that it was not detectible using standard blood tests.

New study describes molecular basis of NeuroAIDS

Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.

Etanercept and chemo might reduce fatigue in cancer patients

Researchers here have found evidence that combining a drug typically used to treat rheumatoid arthritis with chemotherapy might help reduce fatigue and muscle wasting that often afflicts cancer patients.
