Tiny hearts may have big problems with complementary medicine

Giving supplement such as herbs, vitamins, and other natural health products to children taking Warfarin for congenital heart defects could increase their risk of clots, bleeding, and other complications, nurse practitioner Mary Bauman and Dr. Patti Massicotte told the 2008 Canadian Cardiovascular Congress, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.

Blood stored for 29 days or more linked to infection

Blood stored for 29 days or more, nearly 2 weeks less than the current standard for blood storage, is associated with a higher infection rate in patients who received transfusions with the blood.

High-fat diet could promote the development of Alzheimer's

A team of Université Laval researchers has shown that the main neurological markers for Alzheimer's disease are exacerbated in the brains of mice fed a diet rich in animal fat and poor in omega-3s. Details of the study-which suggests that diets typical of most industrialized countries promote the development of Alzheimer's-are outlined in the latest online edition of Neurobiology of Aging.

Brain's 'hate circuit' identified

People who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit', according to new research by scientists at UCL (University College London).

Systems biology and glycomics used to study human inflammatory diseases

An innovative systems biology approach to understanding the carbohydrate structures in cells is leading to new ways to understand how inflammatory illnesses and cardiovascular disease develop in humans. The work was described in two recent publications by University at Buffalo chemical engineers.

Gene against bacterial attack unravelled

Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.

Review of health benefits of grape polyphenols

A growing body of research data suggests that consuming foods rich in polyphenols from grapes - including red wine - helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research.

'Meth' abuse and underage sex, smoking and drinking go hand in hand

Canadian scientists have found a link between methamphetamine abuse and underage sex, smoking and drinking - they say children and adolescents who abuse alcohol or are sexually active are more likely to take methamphetamines.

Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Stress affects older adults more than young ones

A study by researchers at the University of Southern California (USC) has found that older adults change their behaviour more than young adults when under stress and this is particularly so in situations which involve risk.

Protect yourself from flu by wearing a mask and washing your hands

In what has been termed a landmark new study, it is suggested that wearing masks and washing hands prevents the spread of flu-like symptoms.

Link found between brain receptors and schizophrenia

Scientists at Newcastle University in the UK have revealed a link between schizophrenia and a lack of specific brain receptors.

Scientists discover a catalytic antibody that degrades a known appetite stimulant

The antibody works against the gastric hormone ghrelin (pronounced "grell-in"), which has been linked to weight gain and fat storage through its metabolic actions. These findings point towards a potentially novel treatment for obesity that would interfere directly with the some of the biological mechanisms determining weight.

Cholesterol-lowering statins associated with lower risk of death from pneumonia

Individuals who take cholesterol-lowering statins before being hospitalized with pneumonia appear less likely to die within 90 days afterward, according to a report in the October 27 issue of Archives of Internal Medicine.

Brain stimulation improves dexterity

Applying electrical stimulation to the scalp and the underlying motor regions of the brain could make you more skilled at delicate tasks. Research published today in the open access journal BMC Neuroscience shows that a non-invasive brain-stimulation technique, transcranial direct current stimulation (tDCS), is able to improve the use of a person's non-dominant hand.
