Discovery of new drug targets for memory impairment in Alzheimer's disease

Discovery of new drug targets for memory impairment in Alzheimer's disease

In the behavioral test, the team used the fact that mice tend to prefer dark places. If a mouse experiences an electric shock in a dark place, it will remember this event and avoid dark places from then on. However, a mouse with modeled Alzheimer's disease cannot remember if such shock is related to dark places and keeps going back to dark places. The team demonstrated that treating these mice with a MAO-B inhibitor fully recovered the mice's memory.

Cinnamon may be used to halt the progression of Parkinson's disease

(CHICAGO) – Neurological scientists at Rush University Medical Center have found that using cinnamon, a common food spice and flavoring material, can reverse the biomechanical, cellular and anatomical changes that occur in the brains of mice with Parkinson's disease (PD). The results of the study were recently published in the June 20 issue of the Journal of Neuroimmune Pharmacology.

Discovery of a new means to erase pain

Québec City, July 9, 2014 – A study published in the scientific journal Nature Neuroscience by Yves De Koninck and Robert Bonin, two researchers at Université Laval, reveals that it is possible to relieve pain hypersensitivity using a new method that involves rekindling pain so that it can subsequently be erased. This discovery could lead to novel means to alleviate chronic pain.
