High rate of heart attack amongst ethnic minorities in Scotland

The incidence of heart attack amongst Scots of Indian and Pakistani origin is 60-70% higher when compared with non-South Asians, a new report led by the University of Edinburgh has shown.

New insight into the neural computational function represented by "error-related negativity"

Deciphering the subtle, complex electrical signals emanating from the brain has yielded important insights into the still-mysterious neural mechanisms that underlie behavior.

Asymmetric cell divisions are essential for skin development

It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin.

Mutations in the targets of designer drugs critically influence their effectiveness

Two designer cancer drugs differed dramatically in a laboratory test comparing their ability to shut down a mutant, overactive growth signal in lung cancer cells, reports a team headed by scientists at the Dana-Farber Cancer Institute.

Defects in newly discovered pathway may be an overlooked cause of anemia

Researchers studying zebrafish that die from anemia have discovered a new pathway for the synthesis of heme, the deep red, iron-containing molecule that is a component of hemoglobin and myoglobin.

Slower care for heart attack patients treated after hours and on weekends

Heart attack patients treated with primary percutaneous intervention (PCI) at hospitals after hours and on weekends wait longer to receive clot busters and other treatments and have a higher risk of death than those treated during regular hospital hours

First clear evidence that olfaction is uniquely a "dual" sense

In the August 18, 2005, issue of Neuron, researchers report that the smell of chocolate activated different brain regions according to whether the odor was introduced into the olfactory system through the mouth or through the nose.

C. elegans has similar virus-fighting mechanism as humans and can be used in research

Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans.

Doctors should not shy away from giving 80 year olds heart bypass surgery

...suggests research published ahead of print in Heart. Most of those who received the treatment were still alive five years later and had half the risk of death of their peers in the general population, the research reveals.

Loss of a gene called p63 accelerates aging in mice

Researchers have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes.

Biochemical switch that affects how neurons fire in a part of the brain associated with learning

Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer's disease.

Gene expression levels may reveal stage of Huntington's disease

A survey of the genome of patients with Huntington's Disease (HD) has identified potential markers of the progression of this devastating neurological disorder.

Researchers have discovered a gene linked to age-related maculopathy

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Weight control protein may yield new approaches for treating obesity and type 2 diabetes

The findings in mice further suggest that particular variants of the protein SH2-B might underlie obesity in humans, the researchers said.

Breakthrough in human stem cell research

A breakthrough in human stem cell research, producing embryonic-like cells from umbilical cord blood may substantially speed up the development of treatments for life-threatening illnesses, injuries and disabilities.

Adult stem cells may play a role in the development of some forms of cancer

Researchers at UT Southwestern Medical Center have determined that stem cells in a certain region of the brain may be the source of a particular type of incurable brain tumor and may be implicated in other types of brain cancers as well.

Researchers have found evidence that could explain why people continue to sunbathe

Drop by any beach or swimming pool on a summer day, and you'll probably see people doing something they know is bad for them: getting a tan.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

Key toxin could provide for world's first treatment for Alzheimer's

Dr Karen Cullen at Sydney University’s Institute for Biomedical Research is part of a collaborative team which has identified a key component in the progression of Alzheimer’s disease, a finding which may produce the world’s first effective treatment to combat the debilitating effects of the disease.
