We have recently generated lipophilic D-xylose derivatives that increase the rate of glucose uptake in cultured skeletal muscle cells in an AMP-activated protein kinase (AMPK)-dependent manner. The derivative 2,4:3,5-dibenzylidene-D-xylose-diethyl dithioacetal (EH-36) stimulated the rate of glucose transport by increasing the...

At high altitude oxygen delivery to the tissues is impaired leading to oxygen insufficiency (hypoxia). Acclimatisation requires adjustment to tissue metabolism, the details of which remain incompletely understood. Here, metabolic responses to progressive environmental hypoxia were assessed through metabolomic and...

In this work, poly(N-isopropylacrylamide) (PNIPAM) based chemically cross-linked hydrogels are used as novel precipitation and stabilization media for solid lipid nanoparticles (SLNs) for the first time. The hydrogels and the hybrid thermoresponsive composite hydrogels with SLNs were characterized by SEM...
