Université de Montréal researchers are able to see how frontline diabetes drug metformin alters cell glucose uptake using new technology that probes how drugs act on all cellular functions.
A study led by researchers at CHU Sainte-Justine in Montreal confirms that cannabis use is related to impaired and lasting effects on adolescent cognitive development.
Led by UdeM professor Daniel Borsuk, surgeons at Hôpital Maisonneuve-Rosemont announce that four months after the operation, their 64-year-old patient can breathe properly, chew, smell and speak.
Wolf 503b, an exoplanet twice the size of Earth, has been discovered by an international team of Canadian, American and German researchers using data from NASA’s Kepler Space Telescope. The find is described in a new study whose lead author is Merrin Peterson
In the U.S., it's estimated the number of people aged 65 and older will double over the next 30 years. With the first baby boomers now turning 73, the demand for cardiac care is expected to skyrocket, not just in the U.S. but elsewhere as well. Even though they have more cardiovascular problems, fewer women and people over 65 are recruited for randomized clinical trials than men and younger people. To find out, a team of researchers took a close look at the 25 most influential clinical trials for each year in the 20-year period from 1996 to 2015. They compared the age and sex of participants to data published in the U.S. National Health and Nutrition Examination Survey 2015-2016 on the prevalence of cardiovascular disease in America.
Vaccinating asthmatic pre-schoolers against influenza could dramatically reduce their risk of being hospitalized after an attack, Canadian researchers find.
Canadian researchers find that boys who start smoking pot before 15 are much more likely to have a drug problem at 28 than those who start at 15 or after.
Dr. Jean Roy hopes to someday cure patients with multiple myeloma, one of the most common (and still incurable) bone marrow cancers, thanks to a new molecule called UM171 discovered by scientists at Université de Montréal.
A Montreal study reveals that people who travel by car are four times more likely to be injured than people who travel by city bus. Buses are safer for cyclists and pedestrians, too.
An archeological dig in Italy reveals that prehistoric humans made it through a major natural disaster by cooperating with each other – and that's a lesson for our future.
Researchers at Université de Montréal and the research centres of the CHUM and CHU Sainte-Justine are banding together to conquer this rare orphan pediatric disease. They have recently proven what scientists had already suspected: the disease is autoimmune, which means that it attacks patients using their own immune system.
Eight years in the making, a discovery by neuroscientists in Montreal highlights the value of long-term, fundamental research and provides important information for future drug targets.
In much of Africa and Asia, the more schooling a man has, the more likely his partner will take birth control or seek medical help in pregnancy, according to Canadian researchers
A study of 909 planets and 355 stars carried out at the W.M. Keck Observatory reveals that, unlike our solar system, other planetary systems are distinguished by strict regularity.
According to a new psychosocial study, reactive and proactive types of aggressive behaviour in 6-year-old children share most of the same genetic factors. However, their evolution over time seems to be influenced by various environmental factors, suggesting the need to develop different intervention methods.
A study in The Journal of Pediatrics by researchers at Université de Montréal reveals that sexual assault on children leads to an increase in genitourinary health problems in girls, but not boys.
Children who routinely eat their meals together with their family are more likely to experience long-term physical and mental health benefits, a new Canadian study shows.
Summary: Playing 3D-platform video games on a regular basis may improve cognitive functions in seniors and increase grey matter in a brain structure called the hippocampus, a Canadian study suggests
Scientists at UdeM's Department of Biochemistry and Molecular Medicine design better molecules that make it harder for plasmids to move between bacteria.
Université de Montréal research reveals that 29 pregnant women living near natural-gas hydraulic fracturing sites had a median concentration of a benzene biomarker in their urine that was 3.5 times higher than that found in women from the general Canadian population.
A new study examining 200 children with epileptic encephalopathy – epilepsy combined with intellectual or overall developmental disability –identified eight new genes involved in this type of epilepsy thanks to their use of whole-genome sequencing, which had never been done before in an epileptic study of this scope.
A Montreal Clinical Research Institute discovery sheds light on osteocalcin, a hormone produced by our bones that affects how we metabolize sugar and fat.
A new study on cannabis use that involved 1,136 patients (from 18 to 40 years of age) with mental illnesses who had been seen five times during the year after discharge from a psychiatric hospital demonstrates that sustained used of cannabis is associated with an increase in violent behaviour in young people. Moreover, the association between persistent cannabis use and violence is stronger than that associated with alcohol or cocaine.
An exhaustive study of legislative elections in all 91 democracies that were born around the world from 1939 to 2015 finds that in half of them, there was a substantial decline in voter turnout. But what actually caused people to stay home depended on what country they lived in and how democratization happened there.
Medical professor Christopher Rudd and his research team have identified a key new mechanism that regulates the ability of T-cells of the immune system to react against foreign antigens and cancer.
Regulators, take note: A new international study shows that modern diesel passenger cars emit fewer carbonaceous particulates than gasoline-powered vehicles.
