Men are from Mars, women are from Venus - when it comes to brains!

The comedians are right. The science proves it. A man's brain and a woman's brain really do work differently.

Researchers link microRNA - miR 196 - to limb development

A tiny strand of molecules plays a role in how our arms and legs develop and grow - a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University.

Researchers move in on novel therapeutics to inhibit melanoma

Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body.

Sleep-disorders related to breathing suggest increase risk of stroke

Individuals who experience moderate to severe sleep-disordered breathing are four times more likely to have a stroke during the next four years than those who do not suffer from the problem.

Researchers detail mechanism of stroke

In the neural train wreck that is stroke, the cutoff of oxygen kills brain cells through a buildup of acid, as well as by overexciting receptors on the surface of brain cells.

Inexpensive blood test for major parasitic diseases

The National Reference Centre for Parasitology (NRCP), based at the MUHC, is developing a comprehensive and inexpensive blood safety test that will allow clinicians to check for all major parasitic diseases in patients' blood.

Twins, triplets have greater chance of birth defects

Twins, triplets and other multiples have a nearly 50 percent greater chance of being born with birth defects, and boys tend to be more at risk than girls, according to two population-based studies conducted at the University of Florida.

Unexpected link between muscular dystrophy and muscle wasting associated with cancer

A new study provides important insight into the mechanisms of a muscle wasting disorder that interferes with treatment for cancer and has a negative impact on patient survival.

HRAS mutation analysis in Costello Syndrome

Gene mutations in the HRAS sequence are present in most patients affected with Costello syndrome, according to a new study in the American Journal of Medical Genetics. The mutations occurred de novo in patients, meaning, they were not observed in their parents' genes.

CFH Y402H confers similar risk of soft drusen and both forms of advanced AMD

Gene is associated with increased risk of precursor of macular degeneration A variant in a gene called Complement Factor H (CFH) appears to contribute to the increased risk of advanced age-related macular degeneration (AMD) largely or entirely through its impact on the development of a precursor of advanced AMD called soft drusen (small yellowish, extracellular deposits of lipid, protein and cellular debris in the back of the eye), according to a multinational team of researchers.

Findings may help in development of new anti-inflammatory compounds

Virginia Commonwealth University researchers studying the enzyme that triggers inflammation have found that it may be a target for a new class of anti-inflammatory drugs to treat arthritis, asthma, multiple sclerosis, lung and colon cancers and Alzheimer's disease.

Making angioplasty safer

When life-threatening problems occur during angioplasty procedures, doctors may perform emergency coronary artery bypass graft surgery, but data from the Mayo Clinic indicates that need to send patients to emergency surgery has dropped sharply, according to a new study in the Dec. 6, 2005, issue of the Journal of the American College of Cardiology.

Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Depressed heart patients skip medications

Recent studies conducted at the San Francisco VA Medical Center suggest two possible mechanisms for the widely recognized link between depression and adverse outcomes in patients with coronary heart disease: lack of adherence to medication regimens and increased levels of norepinephrine, a stress hormone.

Schizotypy, creativity and mating success in humans

The more creative a person is, the more sexual partners they are likely to have, according to a pioneering study which could explain the behaviour of notorious womanisers such as poets Lord Byron and Dylan Thomas.
