The results of a recent study published in PNAS question the long-term effects of transplanted cells in the brains of patients suffering from Huntington's disease. This study, conducted jointly by Dr. Francesca Cicchetti of Universit© Laval in Quebec, Canada, Dr. Thomas B. Freeman of the University of South Florida, USA, and colleagues provides the first demonstration that transplanted cells fail to offer a long-term replacement for degenerating neurons in patients with Huntington's...

A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. Laboratory experiments showed that three days after a stroke, the affected area of the brain is 20% larger in mice without regulatory T (Treg) cells than in normal mice. Effects on locomotor control are also more severe in mice lacking this type of...

Women who smoke during pregnancy risk delivering aggressive kids according to a new Canada-Netherlands study published in the journal Development and Psychopathology. While previous studies have shown that smoking during gestation causes low birth weight, this research shows mothers who light up during pregnancy can predispose their offspring to an additional risk: violent behavior. What's more, the research team found the risk of giving birth to aggressive children increases among smoking...

A research team supervised by Universit© Laval scientist Marc-Andr© Sirard has identified genetic markers that allow the selection of eggs with the best chance of leading to successful pregnancy after in vitro fertilization (IVF). This finding could both increase the success rate of single embryo transfer and diminish the risk of multiple pregnancies. The details of the method developed by the researchers, for which an international patent application has been filed, are explained...
