All surface and no activity

No static at all.

Permeability of the intestinal epithelial barrier is regulated in response to physiological and pathophysiological stimuli. Recent work has characterized a critical role of acute tight junction regulation in diarrhea secondary to T cell activation and cytokine release. The intracellular mediators of the ensuing barrier dysfunction include myosin light chain kinase, which phosphorylates myosin I...

No Static at All

A correlation between increases in the intracellular Ca concentration of vascular endothelial cells and release of endothelium-dependent relaxing factors was first reported decades ago by Lückhoff et al. In agreement with these formative observations, subsequent studies demonstrated that Ca-sensitive biosynthetic pathways, such as endothelial nitric oxide synthase, as well as small and intermed...

Exclusive breastfeeding: all merits and no peril?

Electronic publishing: all talk and no action?

Suppose they gave a revolution and nobody came? We’re meant to be in the midst of a revolution in life sciences publishing but, for a revolution, it’s awfully quiet. For the moment at least, the ancien régime — in the form of traditional peer review and conventional commercial journals — seems to be winning. The latest fusillade came from Stanford University’s HighWire Press, which has just beg...
