Insulin Delivery: An Ever Changing Frontier

Insulin transport across vascular endothelial cells is the rate limiting step in its time action profile. Glucose uptake in response to insulin is estimated through different techniques and is influenced by insulin sensitivity of the tissue. Glucose clamp technique and minimal model imply an incremental increase in the levels of insulin in the ISF compartment evidenced by increase in glucose up...

The ever-changing landscape of rotavirus serotypes.

Rotavirus is a double-stranded RNA virus that is characterized by substantial genetic diversity. The various serotypes of rotavirus have been determined by the presence of neutralizing epitopes on the outer capsid of the protein shell. At present, 5 rotavirus serotypes (G1, G2, G3, G4, G9) are the predominant circulating strains, accounting for approximately 95% of strains worldwide, although t...

Ever-Changing Landscapes: Transcriptional Enhancers in Development and Evolution

A class of cis-regulatory elements, called enhancers, play a central role in orchestrating spatiotemporally precise gene-expression programs during development. Consequently, divergence in enhancer sequence and activity is thought to be an important mediator of inter- and intra-species phenotypic variation. Here, we give an overview of emerging principles of enhancer function, current models of...

Responding to ever-changing epidemiological dynamics of Ebola virus disease

With the incidence and mortality rates of Ebola virus disease (EVD) in Guinea, Liberia and Sierra Leone now at zero and reports of the largest and most complex EVD outbreak in history no longer on the front pages of newspapers worldwide, the urgency of that crisis seems to have subsided. During this lull after the storm and before the next one, the international community needs to engage in a '...
