Recipients of kidneys from living people are reluctant to accept them before discussions with their donors

Recipients of kidneys from living people are reluctant to accept them before discussions with their donors, new Cardiff University research has shown.

RNA dynamics may help in drug design

Biophysicists have developed a method for studying, in real time, a nanoscale "docking and undocking" interaction between small pieces of ribonucleic acid (RNA), a technique that may be broadly useful in studying structural changes in RNA that affect its function.

Lipid helps cell wall protein fold into proper shape

A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic fibrosis, Alzheimer's disease, and mad cow disease.

New research on atrial fibrillation

Atrial fibrillation is an irregular heartbeat (arrhythmia) in which the atria, or upper chambers of the heart, beat quickly and inconsistently.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Video games can be useful in health care and research

One innovative application of video games in health care is their use in pain management as the degree of attention needed to play such a game can distract the player from the sensation of pain, writes Mark Griffiths, Professor of gambling studies at Nottingham Trent University.

Five basic steps to help doctors identify and treat insomnia in elderly patients

Researchers outline five basic steps to help doctors identify and treat insomnia in elderly patients. This article is published in a special insomnia themed supplement of the Journal of the American Geriatrics Society.

Complicated plasminogen system yields potential therapeutic target; Implications for aging and degenerative diseases

Skeletal muscles naturally repair themselves very efficiently after injury. But when they don’t, otherwise successful recovery following damage from overuse during exercise, surgery or trauma can be stymied. Furthermore, as we age, muscle repair slows noticeably, and in Duchenne Muscular Dystrophy and other degenerative muscle diseases, normal repair functions can’t cope with disease progression.

For over 70's dual pacemakers no better

British researchers say that for people over 70, pacemakers that stimulate only one part of the heart are just as effective as newer and more expensive devices that apply electricity to two of the heart's four chambers.

Canadian researchers look at origins of social aggression

Anyone who has watched a clique of third-grade girls overtly ignore another little girl understands the hurt this type of aggression - called social aggression - can inflict upon others.

Emergency physicians' fear of malpractice in evaluating patients with possible acute cardiac ischemia

A new survey of emergency physicians finds those most concerned about lawsuits are more likely to admit patients with cardiac symptoms and to order more tests. The results will be published by Annals of Emergency Medicine as an early online release July 13 (Emergency Physicians' Fear of Malpractice In Evaluating Patients With Possible Acute Cardiac Ischemia).

Single mutation in a human sodium channel gene can trigger pain in people with primary erythromelalgia

Yale School of Medicine researchers report the first demonstration that a single mutation in a human sodium channel gene can trigger pain in people with an inherited pain syndrome known as primary erythromelalgia, according to a study published this month in the journal Brain.

Transplanted neural stem cells may serve not only as replacement cells for tissue repair, but in some circumstances may also protect the brain from inflammation

Researchers at the San Raffaele Hospital (Milan, Italy) published unexpected results of studies in which immature nerve cells (adult mouse neural stem cells) injected into the blood of mice with MS-like disease were able to suppress the immune attacks that damage the brain and spinal cord tissues.

New search method could aid in the discovery of biomarkers for breast cancer

Using a super-efficient method they invented to search for a type of cancer-related change in all genes of a cell, Dana-Farber Cancer Institute researchers have discovered new evidence about how the "microenvironment" of breast cancers helps drive the cancers' growth and migration.

Researchers gain better understanding of how nerves need to be reconnected after spinal cord injury

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message?

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

New method may accelerate the way cancer-causing genes are found

Researchers at the University of Minnesota Cancer Center and the National Cancer Institute (NCI) have discovered a new method that could accelerate the way cancer-causing genes are found and could lead to a more accurate identification of the genes, according to two studies in the July 14, 2005, issue of Nature.

Biologists determine structure of a common-cold virus

Biologists at Purdue University have determined the combined structure of a common-cold virus attached to a molecule that enables the virus to infect its host, information that ultimately may help researchers develop methods for treating certain viral infections.

Research looks at social blunders when we are under strain or fatigued

Some of us can hold our tongues better than others but even the best of us will blurt out the truth when we're tired, stressed or distracted, according to a new research report.

Researchers identify six genes associated with lymphocytic bronchitis - could mean new test, treatments

Researchers at the San Francisco VA Medical Center (SFVAMC) and the University of California, San Francisco (UCSF) have identified six genes associated with lymphocytic bronchitis, which is thought to lead to obliterative bronchitis (OB), the most common cause of long-term failure of transplanted lungs.
