Skin creams can actually dry the skin

Many people have noticed that as soon as you start using a skin cream, you have to continue with it; if you stop lubricating, your skin becomes drier than when you started.

Sudden cardiac death number one risk for patients on dialysis

In a 10-year study of more than a thousand kidney failure patients, sudden cardiac death emerged as the number one cause of death for patients on dialysis, according to a Johns Hopkins researcher. The study, already published online and appearing in the Nov. 2 issue of Kidney International, identified systemic inflammatory response and malnutrition as key risk factors for the fatal heart attacks.

Gene study sheds new light on lung cancer

A multi-institution team, funded by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH), today reported results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation's leading cause of cancer deaths.

UK teenage suicide rates on the decline

Suicide rates in those aged 10-19 in the UK declined by 28% in the seven year period from 1997-2003, shows a study published today in The Journal of Child Psychology and Psychiatry. The study, carried out by researchers at the University of Manchester, showed that the decline was particularly marked in young males, where rates declined by 35%.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Developing depression after a heart attack increases one’s risk of death or readmission

Science has found many links between depression and other serious medical illnesses, such as cancer, stroke, diabetes, and heart disease. For example, people who develop depression following a heart attack (myocardial infarction) or chest pain (angina) have an elevated risk of cardiac death or hospital readmission over the following year.

Discovery of genetic switch critical for cell survival in Hypoxia

Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. "A transcriptional suppressor, called hairy, is crucial for reducing the mismatch between supply and demand of oxygen," said Dan Zhou, first author on the study, published October 17 in the open-access journal PLoS Genetics.
