Colorectal cancer surgery: gut microbiota helps healing
In a promising study, Canadian researchers have shown for the first time in mice that modifying intestinal flora before surgery could reduce postoperative complications in colorectal cancer patients. CONTENU - Published in the journal Gut, the study by scientists at the CHUM Research Centre (CRCHUM) in Montreal identified two bacterial strains that directly affect whether or not anastomotic leakage, more commonly known as intestinal leakage, occurs.

Link between coffee and kidney disease may depend on genetic variant
Researchers at the University of Toronto and University of Padova have found that the association between heavy coffee consumption and kidney dysfunction hinges on a common genetic variation. In a study, the researchers showed that markers of kidney dysfunction were nearly three times higher in heavy coffee drinkers with a variant of the CYP1A2 gene that makes them slow metabolizers of caffeine than for other heavy coffee drinkers who had a different version of the gene that enables faster caffeine metabolism.

New mathematical model shows how the body regulates potassium
Mathematical model conceptualizes the relationship between kidneys and muscles Having levels of potassium that are too high or too low can be fatal. A new mathematical model sheds light on the often mysterious ways the body regulates this important electrolyte. Potassium, a common mineral abundant in food like bananas and leafy greens, is essential to normal cellular function.

Bacterium decreases effectiveness of immunotherapy
A new study finds that antibodies linked to Helicobacter pylori infections may be associated with lower overall survival outcomes in melanoma patients treated with immunotherapy. CONTENU - Helicobacter pylori is a bacterium that colonizes the stomach lining and is found in more than half of the global population, making it one of the most widespread bacterial infections in the world.

Better understanding cancer and heart disease
A Canadian-led team of researchers finally identifies the molecular mechanism by which a key protein regulates LDL cholesterol. CONTENU Nabil G. Seidah Credit: IRCM In a crucial step towards understanding the mechanisms involved in cardiovascular disease and certain cancers, a Canadian led research team has succeeded in a world first: they've found the molecular mechanism by which the protein PCSK9 degrades the receptor of low density lipoproteins, the richest cholesterol particles in the bloodstream.

AI-powered database to design potential cancer drug in 30 days
AI-powered database to design potential cancer drug in 30 days
In less than a month, researchers have used AlphaFold, an artificial intelligence (AI)-powered protein structure database, to design and synthesize a potential drug to treat hepatocellular carcinoma (HCC), the most common type of primary liver cancer. The researchers successfully applied AlphaFold to an end-to-end AI-powered drug discovery platform called Pharma.AI.

Scientists developing early Alzheimer’s disease detection sensor
By Melissa Shaw Researchers with the SFU Nanodevice Fabrication Group are developing a new biosensor that can be used to screen for Alzheimer's disease and other diseases. An overview of their work has been recently published in the journal Nature Communications. Their sensor works by detecting a particular type of small protein, in this case a cytokine known as Tumour Necrosis Factor alpha (TNF alpha), which is involved with inflammation in the body.

Technologically assisted communication may impair brain development
According to an international study, the use of videoconferencing platforms such as Zoom and FaceTime has a negative effect on social cognition and its development. Videoconferencing services are proliferating-there's Zoom, Teams, Messenger, FaceTime, Skype, WhatsApp-and since the COVID-19 pandemic they have been seeing heavier use than ever before.

Using machine learning to predict brain tumour progression
Waterloo researchers use MRI data to further personalize cancer medicine Researchers at the University of Waterloo have created a computational model to predict the growth of deadly brain tumours more accurately. Glioblastoma multiforme (GBM) is a brain cancer with an average survival rate of only one year.

Smartphone app designed by University of Toronto researchers can significantly improve memory recall
Smartphone app designed by University of Toronto researchers can significantly improve memory recall
Researchers at the University of Toronto have demonstrated that a new smartphone application helps to significantly improve memory recall, which could prove beneficial for individuals in the early stages of Alzheimer's disease or other forms of memory impairment. Dubbed HippoCamera  for its ability to mimic the function of the brain's hippocampus in memory construction and retention, the app enhances the encoding of memories stored in the brain by boosting attention to daily events and consolidating them more distinctly - thus later enabling richer, more comprehensive recall.

Water babies: is it time to demedicalize childbirth?
A recent study shows most women would give birth in water as long as it's safe for their baby, but despite the benefits very few hospital facilities now offer this option. CONTENU - Around 80 percent of women would be interested in giving birth in water, as long as the procedure poses no risks to their newborn.

Study refutes industry claims that ban on menthol cigarettes leads to increased use of illegal smokes
A new research study has found that banning menthol cigarettes does not lead more smokers to purchase menthols from illicit sources, contradicting claims made by the tobacco industry that the proposed ban of menthol cigarettes in the U.S. by the Food and Drug Administration (FDA) will lead to a significant increase in illicit cigarettes.

Western research leads to new understanding of how HIV hides itself in the body 
Western research leads to new understanding of how HIV hides itself in the body 
When the human immunodeficiency virus (HIV) infects a person's body, it permanently inserts its genetic material into the genome where it often remains dormant and barely detectable for years. A major obstacle in finding a cure for HIV has been solving the mystery of how this dormant pool of HIV-infected cells, also called HIV latency, is established.
