Food can trigger overconsumption similar to alcohol and drugs, but it is not the whole story

A large analysis of personality studies has found that people with obesity behave somewhat like people with addictions to alcohol or drugs. But obesity is also a complex condition that cannot be fully explained by the addiction model.

Adoption of methods that could reduce costs and spare animal models

Microsurgery is an intricate and challenging surgical technique that involves using miniature instruments and sutures as fine as a hair strand aided by sophisticated microscopes. In plastic surgery, microsurgery is used to repair small damaged vessels and nerves following trauma, or in reconstructive procedures by moving a component of living tissue from one place of the body to another and reconnecting its vascular supply to this new region to keep its blood supply.

Scientists demonstrate flaws in protein detection tools, and outline a solution

A new study points to the need for better antibody validation, and outlines a process that other labs can use to make sure the antibodies they work with function properly.

Antibodies are used in laboratories and clinics to study proteins, which are the biomolecules that translate information from an organism’s genes into the structure, function, and regulation of its tissues and organs. Genetic mutations can cause protein imbalances or malfunctions, leading to human disease.

TITLE:Augmentation of cell numbers and function in the immune system by in vivo administration of North American (NA) ginseng (Panax Quinquefolium): Assessment in normal and cancer-bearing infant, juvenile, adult and elderly mice

Published on: 7 Oct 2019

Montreal, September 23, 2019 – According to a recent study published in Proceedings of the National Academy of Sciences of the United States of America, the biological clock influences immune response efficacy. Indeed, CD8 T cells, which are essential to fight infections and cancers, function very differently according to the time of day. The study was carried out by a team of researchers led by Nicolas Cermakian, PhD, ofthe Douglas Research Centre, and Nathalie Labrecque, PhD, of the Maisonneuve-Rosemont Hospital Research Centre.

Researchers uncover new protein that plays key role in bacterial infections

Bacterial infections represent a major public health concern, accounting for over 300 million foodborne illnesses and 60% of related fatalities globally.Salmonellaalone is responsible for approximately 93.8 million illnesses and 155,000 deaths annually. Combined with the emergence of antibiotic-resistantSalmonellastrains, it is critical that researchers improve our understanding of the molecular details governing bacterial infections.

Researchers have long been interested in the question of whether a correlation exists between one’s early-life environment and suicide rates, with studies on the topic dating back to the 1980s. However, these studies have focused on individual countries or on only one or few risk factors. As a result, the lack of any meta-analysis of the data has made it difficult to draw any coherent conclusions.
