Spit samples uncover genetic risk factors for paediatric obsessive-compulsive disorder
University of Calgary and The Hospital for Sick Children (SickKids) researchers have discovered genetic risk factors for OCD that could help pave the way for earlier diagnosis and improved treatment for children and youth. Saliva samples from 5,000 kids were scanned and compared to responses using the Toronto Obsessive-Compulsive Scale. The team identified that those with a genetic variant in the

A tummy invader: This bacterial molecule may be key to fighting stomach cancer
Researchers from Osaka University found that H. pylori bacterial strains with low expression of a small RNA molecule called HPnc4160 are more likely to adapt to living in the human stomach. Gastric cancer patients have lower levels of HPnc4160, as well as higher levels of pathogenic bacterial proteins, than individuals without cancer.

To combat gum disease, help oral bacteria evolve
In the latest in their series of investigations on metabolic and bacterial liver disease, researchers from the University of Tsukuba found that people with non-alcoholic fatty liver disease and gum disease benefitted from engaging in regular exercise because it improved their body's own physiology functions and reduced the harmful effects of the bacterial populations residing within the mouth.

Exercise promotes healthy living and a healthy liver
Researchers at the University of Tsukuba have shown that an exercise regimen reduces liver steatosis and stiffness in patients with non-alcoholic fatty liver disease. These gains in hepatic health are mediated through modification of inter-organ cross-talk, circulatory organokine alterations and reductions in inflammation and oxidative stress. Because these benefits are unrelated to weight loss, a
