A team of University of Montreal and 香蕉视频 researchers have devised a method to identify how signaling molecules orchestrate the sequential steps in cell division. In an article published online today in the Proceedings of the National Academy of Sciences, the scientists explain how they could track the relationship between signaling molecules and their target molecules to establish where, when and how the targets are deployed to perform the many steps necessary to replicate an individual cell鈥檚 genome and surrounding structures.

Nanoscale 鈥渃ages鈥� made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, 香蕉视频 researchers report in a new study.聽
The research, published online Sept. 1 in Nature Chemistry, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new possibilities for designing DNA-based nanomaterials.

Researchers at 香蕉视频 have found that sodium 鈥� the main chemical component in table salt 鈥� is a unique 鈥渙n/off鈥� switch for a major neurotransmitter receptor in the brain. This receptor, known as the kainate receptor, is fundamental for normal brain function and is implicated in numerous diseases, such as epilepsy and neuropathic pain.

Research from 香蕉视频 suggests that people who are vulnerable to developing alcoholism exhibit a distinctive brain response when drinking alcohol, according to a new study by Prof. Marco Leyton, of 香蕉视频鈥檚 Department of Psychiatry. Compared to people at low risk for alcohol-use problems, those at high risk showed a greater dopamine response in a brain pathway that increases desire for rewards. These findings, published in the journal Alcoholism: Clinical & Experimental Research, could help shed light on why some people are more at risk of suffering from alcoholism and could mark an important step toward the development of treatment options.

A new network that is bringing together expertise from universities, government and industry is implementing a new vision for training the next generation of medical physicists. Ultrasounds, X-rays, MRIs and nuclear medicine are only a few examples of the essential contributions of medical physicists. The field of medical physics applies the principles of physics to medicine, from diagnosis to treatment, and seeks to quickly transform scientific discovery into clinical applications. Medical physicists are also clinical health care professionals providing service in fields such as radiation therapy, medical imaging, nuclear medicine or radiation protection, to name a few.

Recent technological developments in genomics have revealed a large number of genetic influences on common complex diseases, such as diabetes, asthma, cancer or schizophrenia. However, discovering a genetic variant predisposing to a disease is only a first step. To apply this knowledge towards prevention or cure, including tailoring treatment to the patient鈥檚 genetic profile 鈥揳lso known as personalized medicine 鈥� we need to know how this genetic variant affects health.

Researchers at 香蕉视频 have discovered a new way to join materials together using ultrasound. Ultrasound 鈥� sound so high it cannot be heard 鈥� is normally used to smash particles apart in water. In a recent study, the team of researchers, led by McGill professor Jake Barralet, from the faculties of Dentistry and Medicine, found that if particles were coated with phosphate, they could instead bond together into strong agglomerates, about the size of grains of sand. Their results are published in the journal Advanced Materials.

It happens to all of us at least once each winter in Montreal. You鈥檙e walking on the sidewalk and before you know it you are slipping on a patch of ice hidden under a dusting of snow. Sometimes you fall. Surprisingly often, you manage to recover your balance and walk away unscathed. 香蕉视频 researchers now understand what鈥檚 going on in the brain when you manage to recover your balance in these situations. And it is not just a matter of good luck.
