Many changes take place in the brain long before symptoms appear. This has been shown in mice in two studies of prion diseases in which the brain gradually deteriorates. The results suggest that changes can be studied extremely early in the disease process, which is important if we are to […]

McMaster University researcher Sheila Singh and her team have discovered how glioblastoma, a lethal brain cancer, can evade treatments and kill. The researchers found the cancer cells that survive the first round of radiotherapy or chemotherapy do so by mutating during the post-treatment minimal residual disease (MRD) or dormant state. […]

Diabetes affects about three million Canadians, with the prevalence increasing yearly. About half of those living with diabetes experience nerve pain and sensory issues—called diabetic neuropathy—ranging from mildly uncomfortable to severely debilitating. University of Saskatchewan (USask) College of Medicine PhD student Joseph Neapetung is focusing his research on investigating the […]

Researchers at Linköping University have discovered a biological mechanism that increases the strength with which fear memories are stored in the brain. The study provides new knowledge on the mechanisms behind anxiety-related disorders, and identifies shared mechanisms behind anxiety and alcohol dependence. The ability to experience fear is essential to […]

Strokes are the third leading cause of death in Canada and have impacted close to 880,000 Canadians over the age of 20. “A stroke is caused by a loss of blood flow to brain cells. Without urgent intervention this may cause those cells to die because they constantly need energy […]

A group of University of Saskatchewan (USask) researchers are looking into how nutrition, particularly dairy foods, affect growth and development in Canadian children. The research team is currently recruiting Canadian children aged 5 to 11 years old who have no history of chronic conditions and who are not currently taking […]

Women and men share most of the same risk factors for cardiovascular disease (CVD), a large international study has found — the first such study to include people not only from high-income countries, but also from low- and middle-income countries where the burden of CVD is the greatest. The study has […]

The immune cells of patients who received hospital care for COVID-19 early in the pandemic were still affected six months later. A new study suggests that infection by the SARS-CoV-2 virus leaves significant effects long after the patient is symptom-free. The results have been published in Frontiers in Immunology. “We […]
