The lactogenic hormone prolactin (PRL) has been known to affect Ca(2+) and electrolyte transport in the intestinal epithelium. In the present study we analyzed ion transport in mouse proximal and distal colon, and acute changes induced by PRL. In the proximal colon, carbachol activated a Ca(2+) dependent Cl(-) secretion that was sensitive to DIDS and NFA. In the distal colon, both ATP and carba...
We have investigated the volume-activated transport of organic solutes in flounder erythrocytes. Osmotic swelling of cells suspended in a Na(+)-free medium led to increased membrane transport of taurine, glucose, and uridine. For each compound there was a significant lag period (1-2 min at 10 degrees C) between cell swelling and activation of the flux. The volume-activated fluxes of each of the...
Abstract MXenes are emerging layered materials that promising for electrochemical energy storage and (opto-)electronic applications. A fundamental understanding of charge transport in is essential such applications, but has remained under debate. While theoretical studies pointed to efficient band transport, device measurements have revealed thermally activated, hopping-type transport. Here we ...
