Ageing per se increases susceptibility to lipid induced insulin resistance in rats

Posted on August 19, 2010 by Colby Vorland

I am constantly on the lookout for studies on how biochemical mechanisms shift with age, the significance of these changes and how nutrition and lifestyle interact with them to potentially affect health.  Ageing itself is clearly an immensely complex process, and teasing … Continue reading →

Carbon Dioxide and Lifespan in Drosophila

Posted on May 10, 2010 by Colby Vorland

My first post to this blog began with a fascinating study by Scott Pletcher that found odor from yeast can accelerate the ageing of dietary restricted Drosophila.  His group recently published another study that adds to our understanding (1), which … Continue reading →

Water intake and protein:carbohydrate ratio confound Drosophilia calorie restriction studies, implications?

Posted on December 1, 2009 by Colby Vorland

Ja et al. (1) recently published the results of a study exploring how hydration and nutrient manipulation effects the results of calorie restriction in Drosophilia. In non mammalian models, feeding rate is difficult to control, and often food is diluted … Continue reading →

The confounding role of sensory perception in calorie restriction and ageing research

Posted on September 4, 2009 by Colby Vorland

My first post to this blog will begin with a thought provoking paper on how the olfactory system fits in to the longevity promoting effects of calorie restriction. Calorie restriction is the most studied and reliable way to extend secondary … Continue reading →
