Toronto, June 28 - The lightest and the heaviest foetuses are at much higher risk of being stillborn than those of average weight, new research has found.
Toronto, April 25 : Common anti-depressants seem to be doing patients more harm than good, says a new study.
"We need to be much more cautious about the widespread use of these drugs," says Paul Andrews, evolutionary biologist at McMaster University, Canada, who led the study.
Toronto, April 23 : Researchers at Simon Fraser University have concluded that cholesterol may have a few good qualities like slowing or halting cancer cell growth, after all the bad publicity it has received for its role in heart disease or obesity.
They arrived at this conclusion while trying to understand how cholesterol moves around inside cells in the fat's journey to cell surfaces where it reinforces their outer membrane.
Toronto, April 11 : Victims of obsessive compulsive disorder (OCD) fret endlessly over whether they have locked the door or turned off the gas stove. Now, a new way to treat it is being tested.
Adam Radomsky, professor of psychology at the Concordia University, is now testing a new way to treat OCD, a debilitating behaviour that could just substantially improve the quality of life for many.
Toronto, April 10 : The belief in how long you will live may subconsciously influence major decisions such as marriage, divorce, abortion, having a child or attending university.
"Life expectancy might be driving all of these major decisions," says study author Daniel Krupp, post doctoral fellow in the Queen's University math department who has a background in psychology and biology.
Toronto, March 6 - Researchers have cracked the structure of a virus that causes potentially fatal brain swelling and paralysis in children, a development that could open the way to better antiviral drugs.
Toronto, March 1 : In a lab setting experiment, Scientists have perfected a cutting-edge drug to protect the brain against the damaging effects of a stroke, thus accelerating the process to reduce thousands of stroke-related deaths.
Over 1,000 attempts to develop such drugs worldwide have failed to be translated to a stage where they can be used in humans, leaving a major unmet need for stroke treatment.
Toronto, Feb 20 - Certain foods could give you extra protection against chronic diseases.
Researchers from the University of Guelph led by Brian McBride, have found a way to enrich milk with DHA (docosahexaeonic acid), an essential nutrient that many people are lacking.
Toronto, Feb 17 - Burning coal, wood or charcoal for cooking kills two million people worldwide, each year - more than malaria - thanks to severe respiratory diseases this causes through indoor pollution, warns an expert.
Toronto, Feb 14 : Researchers have found the key to how memories of pain are stored in the brain, especially in nerve cells (neurons), and how they can be erased to ease pain.
The central nervous system is known to "remember" painful experiences, that they leave a memory trace of pain.
And when there is new sensory input, the pain memory trace in the brain magnifies the feeling so that even a gentle touch can be excruciating.
Toronto, Feb 6 - Most athletes would swear by the pain-relieving, muscle recovery-promoting benefits of massaging, which has now been validated by scientific evidence.
On the cellular level, massage reduces inflammation and promotes the growth of new mitochondria (cellular powerhouse) in skeletal muscle, says a new study.
Toronto, Feb 3 : Heart failure could also be linked to thinning of bones (osteoporosis), an offshoot of old age.
"Our study demonstrates for the first time that heart failure and thinning of bones go hand in hand," said Sumit Majumdar, University of Alberta in Edmonton, Canada, who led the study.
Toronto, Jan 30 - Attentiveness in kindergarten (KG) is the key to developing "work-oriented" skills in school children later as adults.
Toronto, Jan 18 - A minimally invasive surgical procedure called renal denervation can significantly lower blood pressure (BP) in patients who are unable to control it with drugs.
The nearly painless procedure has been tried out for the first time by doctors at the Peter Munk Cardiac Centre (PMCC) in Canada. It involves de-activating nerves located on the outside of the artery that feeds blood to the kidney, thereby lowering BP.
Toronto, Jan 18 - A defective mitochondria, which acts as a cellular battery, could be the trigger for a devastating neurodegenerative disease, showing up in toddlers just as they begin to walk, reveals a study.
The research throws new light on the disease and reveals an important common link with other brain diseases, potentially opening the way to new therapeutic approaches for those who suffer from them.
Toronto, Jan 17 - Scientists have found a way to block the Hepatitis C virus (HCV) and possibly benefit 170 million people worldwide.
The breakthrough opens the way for new therapies to treat HCV which targets the liver and is among the leading causes of liver cancer and liver transplant globally.
Toronto, Jan 17 - A radical technique that requires only about 20 minutes in an outpatient clinic may replace long and costly eardrum surgery in children.
The quick procedure, requiring only local anaesthesia, will be much easier on patients and parents and also substantially reduce long waiting lists, stretching to 18 months.
Toronto, Jan 12 - Depressed employees become more productive after undergoing treatment than those who don't receive treatment, suggests a study.
The study from the Centre for Addiction and Mental Health (CAMH) examined data from a large-scale community survey of employed and recently employed people in Alberta.
Toronto, Jan 6 - Writing your most important values on a piece of paper can literally knock you into shape as it might make you feel better and obliterate the need to eat to do the same.
"We have this need to feel self-integrity," says Christine Logel of Renison University College, University of Waterloo.
Toronto, Jan 2 - Scientists investigating rare ovarian, uterine and testicular tumours have stumbled upon on a mutated gene that is surprisingly common to all of them.
David Huntsman, genetic pathologist at the University of British Columbia (UBC) Cancer Agency and Gregg Morin, from its Michael Smith Genome Sciences Centre, led a team which found mutations in rare, seemingly unrelated cancers, all tied to the same gene, DICER.
Toronto, Dec 30 - Post-menopausal women should think twice before going in for hormone replacement therapy (HRT) because it is tied to breast cancer globally, reveals a study.
The study by McMaster University researchers, that found consistent evidence that use of HRT is linked to breast cancer globally, comes at a time when more women are asking for this medication to control hot flashes and other symptoms of menopause.
Toronto, Dec 23 - Drugs that checkmate cancer could also combat pathogens that have become highly resistant to antibiotics - a problem spreading globally.
"Our study found that certain proteins, called kinases, that confer antibiotic resistance are structurally related to proteins important in cancer," says Gerry Wright, professor of biochemistry at McMaster University.
Toronto, Dec 12 - Alcohol consumption, which gives a high, has long been associated with unsafe sex. Now, a new study directly relates it to HIV infection.
In spite of substantial efforts to prevent unsafe sex, HIV incidence in most high-income countries remains unchanged over the past decade or has increased in some instances.
Toronto, Dec 7 - A video game known as Phylo has lent a cutting edge to genetic research, especially understanding the role DNA plays in Alzheimer's, diabetes and cancer, reveals a study.
The web-based video game has been developed by Jerome Waldispuhl of the McGill School of Computer Science along with collaborator Mathieu Blanchette.
Toronto, Dec 7 : Infants are quite capable of figuring out whether you are sincere or not -- they will be wary if they have been tricked previously, reveals a study.
