Opioid use disorder: flexible treatment at home proves effective
Opioid use disorder: flexible treatment at home proves effective
A pan-Canadian team announces initial results of the national OPTIMA study comparing the efficacy of two models of care for treating opioid use disorder. Did you know that more than 26,500 Canadians died from opioid intoxication between January 2016 and September 2021? Or that more than 350,000 people who used drugs containing opioids to relieve their pain did so problematically? In Quebec alone, 339 people died from opioid intoxication between January and September 2021, according to the latest data from the Public Health Agency of Canada.

How does the brain learn?
An international team co-led by UdeM computational neuroscientist Eilif Muller has simulated how synapses in the neocortex change - to better understand how we learn. Everyone knows the human brain is extremely complex - but how does it learn, exactly? Well, the answer may be a lot simpler than commonly believed.

Theta waves: a marker of emotional regulation
New findings on theta waves generated in the brain during emotional regulation could lead to more treatment options for disorders such as anxiety and schizophrenia. Without realizing it, we all rely on emotional regulation many times a day. It's the process by which we mitigate the effect of disturbing stimuli in order to stay focused, improve our well-being and respond to demands from our environment.

Regenerating the heart after an attack
Regenerating the heart after an attack
Zebrafish are put under the lens at CHU Sainte-Justine Research Centre to see how they repair damaged tissue - with some surprising results. Heart attacks are damaging, and the severity depends on how long blood flow has been interrupted; when temporarily deprived of oxygen, heart cells die. In addition, the heart can't rebuild its own tissue, leading to its failure, the main cause of mortality and morbidity worldwide.

Does grief depend on how the loved one died?
Ph.D. candidate Philippe Laperle explores the grief experience after medical assistance in dying and natural death with palliative care. Is the grief experience different for individuals who have lost a loved one by medical assistance in dying (MAiD) compared to natural death with palliative care (NDPC)? Philippe Laperle examines this sensitive issue in a recent article published in the Journal of Death and Dying , based on his Ph.D.

Where are the next zoonotic viruses lurking?
A research team has used AI to produce a list of animal viruses that could jump the species barrier and cause infections in humans. Until recently, we knew of only two percent of the possible interactions between mammals and viruses, or the "virome." However, a new artificial intelligence (AI) technique has identified potential new host-virus interactions, increasing the size of the known virome by a factor of 15.

Gun ownership and homicide in the U.S.: a stronger correlation
A study by UdeM economics professor Karim Chalak finds that U.S. gun ownership is more closely associated with risk of homicide than was previously thought. In 2017, there were nearly 40,000 gun-related deaths in the United States, including homicides and suicides. To delve into this alarming statistic, U.S.-trained Université de Montréal economist Karim Chalak and his coauthors did an econometric study of the rate of U.S. gun ownership and the associated risk of death, and found it to be much higher than previously thought.

Cooperative molecular networks may have been the spark of life on other planets
Cooperative molecular networks may have been the spark of life on other planets
According to a UdeM study, life could have emerged on an exoplanet as a result of a type of biochemical cooperation that is more likely to occur in nature than we might think! Darwin's theory of evolution probably isn't the full explanation for the emergence of life. Even in a barren environment conducive to fierce competition, cooperation between molecular networks may have spawned life on Earth and, by extension, elsewhere in the universe.

Cell division in embryos: not a textbook case of symmetry
Two researchers from the CHUM Research Centre find that cell division in mouse embryos is not at all symmetrical, quite unlike what science textbooks say. As cell biologists, Université de Montréal professor Greg FitzHarris and his PhD candidate Lia Paim are very interested in fertility and what happens inside the eggs and embryos of the mice they study in their lab.
