Tick bite log

About two months ago, I noticed, for the first time ever, the dreaded red circle around one of my first tick marks of this season. The mark was in the vicinity of the hollow of my left knee, and it was left by a tick that I had discovered about two days after it must have lodged there, plenty of time for it to dump its bacterial payload in my bload. This late discovery is fairly typical for me. I've never been very careful with registering tick bites, and over the year, I've discovered many ticks only after accidentally beheading them while thoughtlessly scratching their abdomen away.

Metabolism & Nutrition – Tutorial 1: Caloric restriction (CR)

For the 2015 Metabolism & Nutrition course at the RuG, I'm asked to read two papers on two parralel studies on increased longevity of rhesus monkeys (Macaca mulatta) through caloric restriction (CR). Colman et al. (2014) report a positive effect of caloric restriction on longevity for the study at the Wisconsin National Primate Research Center (WNPRC), but these effects could not be confirmed by Mattison et al. (2012), with macaques kept at the US National Institute on Aging (NIA). Read More »

Metabolism & Nutrition – Tutorial 6: Metabolic regulation

Tutorial no. 6 for the RuG Metabolism & Nutrition course builds on the lecture [Lecture 5] on the same subject by Hans Jonker. It is also the subject which me and two others have to give a presentation on this Friday for the rest of Group C to initiate the group discussion. The article which is to be discussed during our presentation and the rest of the tutorial is a 2014 Nature publication [doi:10.1038/nm.3760] by Sungsoon Fang et al., titled “Intestinal FXR agonism promotes adipose tissue browning and reduces obesity and insulin resistance.” Read More »
