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.
Toronto, Dec 6 - Researchers have pinpointed the brain area that controls our ability to correct our movement after we have been hit or bumped.
The fact that humans rapidly correct for any disturbance in motion shows the brain understands the physics of the limb.
"To say this process is complex is an understatement," said Stephen Scott, neuroscience professor and motor behaviour specialist at the Queen's University.
Toronto, Dec 5 - Those who suffer from depression or stress are twice as likely to have a heart attack than those with an even outlook.
A study led by Concordia University has found that the depressed also recover more slowly after exercise than those who are non-depressed.
These findings point to the importance of testing for cardiovascular disease among people suffering from major depression, the journal Psychophysiology reports.
Toronto, Dec 1 - Eating protein-rich foods, especially dairy products, protect bones when overweight or obese young women try to shed weight through dieting, suggests a new study.
The study found bone health improvements were particularly evident due to the high density of bone-supporting nutrients such as calcium, vitamin D and dairy-based protein.
Toronto, Nov 17 : High levels of TV viewing by kids can elevate their chances of developing heart disease later in life, but significantly high use of computer does not.
Different kinds of sedentary behaviour produce different consequences for young people's health, according to the findings from Queen's University, Canada.
Canada, Nov 12 : Many people are often barred from eating common grapefruit as it can negatively interact with their prescription drugs, but there may now be some hope for those with a longing for the tangy citrus.
Scientists at the University of Florida have bred a new type of grapefruit that they expect will enable people on meds to enjoy the fruit without any drug interaction.
Toronto, Oct 28 - A fish predator's mere presence can trigger enough stress to kill a dragonfly. Scientists suggest that the finding could be used as a model for studies on the lethal effects of stress on all organisms.
Toronto, Oct 24 - Reconstruction of breasts after their whole or partial removal during mastectomy may help women improve their psychosocial and sexual well-being.
Mastectomy is the medical term for the surgical removal of one or both breasts, partially or completely, especially to prevent breast tumours from spreading.
Toronto, Oct 7 : Even three-year-olds can sense that while man-made objects are owned, natural products like pine cones and sea shells are beyond ownership, new research has found.
"This provides the first evidence about how children judge the ownership of things based on whether those things are artificial or natural," said psychologist Karen Neary of Ontario's University of Waterloo.
Toronto, Oct 5 : A new gene could increase chances of developing osteoporosis, a "silent" disease characterised by increased bone fragility and risk of fracture.
Eighty percent of hip fractures are related to osteoporosis, resulting in death in up to 20 percent of cases, and disability in 50 percent of the survivors.
Toronto, Sep 20 : Red wine, popularly touted as a remedy for a host of medical condtions, has no protective qualities to prevent heart disease, says a new study.
"In particular, red wine has no special, protective qualities when it relates to cardiovascular disease," said Kathy Bell, CEO, Heart Foundation (Victoria).
Toronto, Sep 14 : Here's good news for those suffering from fatty liver disease - pure maple syrup is likely to boost your liver, new research suggests.
Keiko Abe of the University of Tokyo's Graduate School of Agricultural and Life Sciences conducted the pilot study on rats.
Toronto, Sep 2 : Workouts can keep obesity at bay by turning influential stem cells into bone, not fat, boosting our capacity to make blood and improving overall health.
The body's mesenchymal stem cells or MSCs are most likely to become fat or bone, depending on which path they follow. MSCs can also turn into a variety of cell types.
Toronto, Aug 10 : Research by an Indian-origin scientist has shown that brain protein may actually hold the key to keeping appetite and blood sugar under control and keep unwanted pounds away.
Suraj Unniappan, associate professor in biology at Canada's York University, is probing the metabolic effects of a protein called nesfatin-1 present in the brain.
Toronto, July 12 : A new study has found that food addiction is an identifiable condition with clinical symptoms, characterised by a psycho-behavioural profile as in conventional drug-abuse disorders.
The study suggests that people who become dependent on highly palatable foods engage in a compulsive pattern of consumption, similar to that of drug and alcohol addicts.
Toronto, July 11 : A new strain of gonorrhoea, resistant to all available antibiotics, is likely to turn the once easily treatable infection into a global health threat.
Universite Laval researchers in Canada successfully identified an unknown variant of the bacterium that causes gonorrhoea, neisseria gonorrhoeae.
Toronto, July 11 : Scientists have stumbled upon unusual genetic configurations that explain why more schizophrenic patients tend to have them than normal people.
'De novo' mutations are genetic errors that are present in such patients but not in their parents, or in normal people, according to scientists led by Guy A. Rouleau of the University of Montreal and director of CHU Sainte-Justine Hospital.
Toronto, July 8 : Humans are so good at perceiving others that even a few dots on a screen representing the major joints of a body are enough to retrieve all the information we need -- as long as they move.
This process is called biological motion perception, but what role does the visual system play in that process? Does it use it only to connect the dots to create a coherent, or "global," structure?
Toronto, July 1 : The action a person is planning can now be foretold moments before it is executed, claim researchers.
"This is a considerable step forward in our understanding of how the human brain plans actions," says the study co-author Jason Gallivan, University of Western Ontario doctoral student.
Toronto, June 29 : Did you know that walking to the photocopier and fidgeting at your desk may not be entirely pointless?
In fact, the intensity and the duration of such activities may be contributing more to your cardio-respiratory fitness than you might think.
Toronto, June 23 : When you drop a cake of soap into a sink full of greasy water, the grease recoils and retreats to the edges of the sink.
Now, what if the sink was a cancer cell, the globs of grease were cancer-promoting proteins and the soap was a potential drug?
