Mirror-image version of existing drugs would last longer in the body thanks to their ability to avoid breakdown by enzymes in the stomach and bloodstream. For patients, this means less frequent drug injections and more medicines could potentially be made available as pills. Designing these drugs has been tricky, however. Now a team of researchers led by Philip Kim, a professor of computer science and molecular genetics in the University of Toronto’s Donnelly Centre for Cellular and Biomolecular Research, has developed a new technology for making mirror-image peptides, which bind and activate receptors on the surface of cells.

They created mirror-image versio...

Orthogonal cancer targeting strategy using nanomicelles. a Schematic of the process of photoactivation of Titanocene in disseminated cancer cells in the bone marrow microenvironment

Tumor imaging technique has potential as anti-cancer weapon, mouse study shows. Unlike traditional light therapy – which is limited to the skin and areas accessible with an endoscope – this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School of Medicine in St. Louis. Light emitted as part of traditional cancer-imaging techniques, to locate metastatic tumors, also can trigger light-sensitive drugs, according to the new study...

How well do plant based alternatives fare nutritionally compared to cow’s milk? Journal of Food Science and Technology, 2017; 55 (1): 10 DOI: 10.1007/s13197-017-2915-y

A new study looks at the four most-commonly consumed types of milk beverages from plant sources around the world – almond milk, soy milk, rice milk and coconut milk – and compares their nutritional values with those of cow’s milk. After cow’s milk, which is still the most nutritious, soy milk comes out a clear winner. How healthy is your almond milk really? It may taste good and may not cause you any of the unpleasant reactions caused by cow’s milk...

The MIND diet has 15 dietary components, including 10 “brain-healthy food groups” and five unhealthy groups — red meat, butter and stick margarine, cheese, pastries and sweets, and fried or fast food.

A diet created by researchers at Rush University Medical Center may help substantially slow cognitive decline in stroke survivors, according to preliminary research presented on Jan. 25 at the American Stroke Association’s International Stroke Conference 2018 in Los Angeles. The findings are significant because stroke survivors are twice as likely to develop dementia compared to the general population. The diet, known as the MIND diet, is short for Mediterranean-DASH Diet Intervention for Neurodegenerative Delay...
