Where is my arm?

The subject of proprioception is concerned with the body’s ability to sense its own actions. One aspect that Uwe Proske, below, has been studying recently is the kinaesthetic sense, the sense of position and movement of our limbs

The amazing versatility of hPEPT1

hPEPT1 is the port of entry into enterocytes of all possible di- and tri-peptides resulting from the digestion of dietary proteins. Since the mid-1990s, it has been exploited as a tool to enhance the oral availability of an ever-increasing number of drugs and prodrugs –both peptidic and non-peptidic. Recently, Monica Sala-Rabanal and colleagues uncovered the molecular mechanism by which peptides and drugs alike make their way into the human enterocytes

Going with the flow: just say NO to oxygen radicals

Endothelial cells are permanently exposed to shear stress by the flowing blood. Shear stress increases the endothelial formation of nitric oxide. But what happens to oxygen radicals during flow? Henning Morawietz and colleagues analyzed the flow-dependent regulation of the NADPH oxidase as a major source of endothelial oxidative stress
