Should research volunteers be told results?

Every year, hundreds of thousands of Americans volunteer to take part in medical research studies, from simple health surveys to detailed analyses of their DNA or tests of experimental medicines.

New molecular mechanism for colorectal cancer

Scientists in Portugal just found a new molecular mechanism behind colorectal cancer in which a mutated and a normal, but over-expressed, gene cooperate and are both needed to create the disease.

Kidney cell suicide in diabetes patients

Diabetes is the leading cause of renal failure that requires dialysis. The disease generates such a hostile environment that it forces the kidney cells to kill themselves, progressively reducing the renal functions of the kidneys.

More evidence red wine keep hearts young

How, scientists wonder, do the French get away with a clean bill of heart health despite a diet loaded with saturated fats?

A genetic tool for cleaner water

A genetic tool used by medical researchers may also be used in a novel approach to remove harmful microbes and viruses from drinking water.

You may not be what you eat after all!

A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say.

Thinness versus obesity not directly linked to eating habits

Whether you are fat or thin isn't directly determined by your eating habits, suggest researchers who report new findings made in worms in the June issue of Cell Metabolism, a publication of Cell Press.

Discovery of genes that regulate glucose levels

In an effort to understand how genes work, a collaborative study which includes the University of Southern California (USC) has identified a gene that regulates glucose levels. The results, which will be published in the July issue of the Journal of Clinical Investigation and is currently available online, may provide further understanding of the underlying causes of diabetes.

New clues for nerve cell repair

A new study at the Montreal Neurological Institute at McGill University identifies a key mechanism for the normal development of motor nerve cells (motor neurons) - cells that control muscles. This finding is crucial to understanding and treating a range of conditions involving nerve cell loss or damage, from spinal cord injury to neurodegenerative diseases such as ALS, also known as Lou Gehrig's disease.

Flow of potassium ions in brain cells is key to sexual arousal

When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount.

By 2024 one in seven women will be diagnosed with breast cancer

Experts in Britain are predicting that by 2024 one in seven women will be diagnosed with breast cancer if there is not an improvement in public health trends.

Personal genomes may lead to personalized vitamin supplements

As the cost of sequencing a single human genome drops rapidly, with one company predicting a price of $100 per person in five years, soon the only reason not to look at your "personal genome" will be fear of what bad news lies in your genes.

Mouse ovaries and testes age in unique ways

Aging leads to large changes in gene activity in the ovaries of mice, but only limited changes in testes, according to research published in the open-access journal, BMC Biology.

New genetic mutations involved in inflammatory intestinal disorders discovered

The discovery of new genetic mutations involved in inflammatory intestinal disorders could lead to a better understanding of these common conditions, two scientists told the annual conference of the European Society of Human Genetics today (Monday 2 June).

Distinct clusters of genetic markers linked to treatment responses for smoking cessation

Scientists have identified distinct clusters of genetic markers associated with the likelihood of success or failure of two smoking cessation treatments, nicotine replacement therapy (NRT) and the medication bupropion (Zyban). This study, supported by the National Institute on Drug Abuse (NIDA) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), was published in the June issue of the journal Archives of General Psychiatry.

Salmonella bacteria found in garden birds are sensitive to antibiotics

Scientists at the University of Liverpool have found that Salmonella bacteria found in garden birds are sensitive to antibiotics, suggesting that the infection is unlike the bacteria found in livestock and humans.

Researchers find gene signature profile for metastasis

A common signature of tiny, specific pieces of non-coding genetic material known as microRNAs (miRNAs) may be directly involved in the spread of cancer to other parts of the body.

Expert cautions against rushing into genetic testing

Just because scientific advances now allow individuals to learn their genetic make-up doesn't mean they should rush into genetic testing in hopes of making revolutionary improvements to their health, cautions a geneticist and practicing physician at the University of North Carolina at Chapel Hill.

Gene discovery could help answer basic questions of upright walking

What are the genes implicated in upright walking of humans? The discovery of four families in which some members only walk on all fours (quadrupedality) may help us understand how humans, unlike other primates, are able to walk for long periods on only two legs, a scientist will tell the annual conference of the European Society of Human Genetics tomorrow (Monday 2 June).

Researchers pinpoint gene mutations responsible for 10 percent of non-familial cases of schizophrenia

Scans of the genome of patients with schizophrenia have revealed rare spontaneous copy number mutations that account for at least 10 percent of the non-familial cases of the disease.
