Around one in four Montrealers take some kind of anti-depressant, and according to new research, the drugs are passing into the waterways and affecting fish. The findings are internationally significant as the city’s sewage treatment system is similar to that in use in other major cities, and moreover, it is reputed to be the third largest treatment system in the world. Lead by Dr. Sébastien Sauvé at the University of Montreal’s Department of Chemistry and André Lajeunesse, a PhD candidate, the research team found that the drugs accumulate in fish tissues and are affecting the fish’s brain activity.

Migraines are a chronic brain condition characterized by attacks of a throbbing headache, of medium or strong intensity, possibly associated with nausea, vomiting, photophobia and intolerance to sounds (phonophobia). In about a third of cases, seizures are accompanied by neurological symptoms, usually visual, known as auras. The disorder occurs in those who are genetically susceptible. The World Health Organization estimates that worldwide there are 324 million people who suffer from in this condition. (more…)

*Researchers discover molecular mechanism behind drink’s prophylactic effect*

Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG. (more…)

A study by Newcastle University in Britain, indicates that green tea may protect the brain from diseases such as Alzheimer’s and other types of dementia. The research, published in the journal Phytomedicine, also suggests that the ancient Chinese remedy that has been popularized throughout the world may also have an important role in protecting the body against cancer.

In the study, scientists investigated whether the beneficial properties of green tea, which had already been proven in newly prepared and undigested tea, were still active once the tea was digested. (more…)
