Pleiotropic Functions of the Organic Solute Transporter Ost-Ost

The heteromeric organic solute transporter alpha-beta (Ost -Ost ) is expressed at relatively high levels on the basolateral membrane of enterocytes, where it plays a critical role in the intestinal absorption of bile acids and the enterohepatic circulation. However, this transporter is also expressed in nearly all human tissues, including those that are not normally thought to be involved in bi...

Remembering remembering.

We developed a laboratory analogue of the "forgot-it-all-along" effect that J. W. Schooler, M. Bendiksen, and Z. Ambadar (1997) proposed for cases of "recovered memories" in which individuals had forgotten episodes of talking about the abuse when they were supposedly amnestic for it. In Experiment 1, participants studied homographs with disambiguating context words; in Test 1 they received stud...

On the ost of using

OST alpha-OST beta: a key membrane transporter of bile acids and conjugated steroids.

The organic solute and steroid transporter, Ost alpha-Ost beta, is an unusual heteromeric carrier that appears to play a central role in the transport of bile acids, conjugated steroids, and structurally-related molecules across the basolateral membrane of many epithelial cells. The transporter's substrate specificity, transport mechanism, tissue distribution, subcellular localization, transcri...

On Feferman's operational set theory OST

We study OST and some of its most important extensions primarily from a proof-theoretic perspective, determine their consistency strengths by exhibiting equivalent systems in the realm of traditional set theory and introduce a new and interesting extension of OST which is conservative over ZFC.
