Immune reactions and mitogen stimulation of mammals and chickens lead to an increase of glucocorticoid (GC) plasma levels concomitant with the immune response. Interleukin (IL) 1, one of the most important glucocorticoid increasing factors produced by cells of the immune system, acts via the hypothalamo-pituitary-adrenal (HPA) axis. This pattern of(More)
We measured in simultaneously withdrawn cerebrospinal fluid (CSF) and serum samples from 56 endocrinologically grossly normal patients the concentrations of several lipophilic unconjugated steroids [i.e. dehydroepiandrosterone (DHEA), androstenedione, cortisol, progesterone, testosterone] and their hydrophilic counterparts, i.e. DHEA-sulfate, or hydrophilic(More)
We connect Lukasiewicz logic, a well-established many-valued logic, with weighted logics, recently introduced by Droste and Gastin. We use this connection to show that for formal series with coefficients in semirings derived from MV-algebras, recognizability and definability in a fragment of second order Lukasiewicz logic coincide.
Assigning semantics to logic programs via selector generated models (Schwarz 2002/2003) extends several semantics, like the stable, the inflationary, and the stable generated semantics, to programs with arbitrary formulae in rule heads and bodies. We study this approach by means of a unifying framework for characterizing different logic programming(More)
The genomic mode of action is believed to represent the predominant effect of a steroid hormone. Recently, however, rapidly manifesting, non-genomic effects have also been observed. These are mediated mostly by allosteric interaction of a steroid with heterologous target structures such as membrane receptors, a prototype example being the GABAA. Here we(More)
As a glycoprotein hormone, human chorionic gonadotropic (hCG) is not a single molecular entity but this term rather comprises an array of molecular variants such as hCG, hCG beta, hCGn, hCG beta n, hCG beta cf, -CTPhCG, hCG beta CTP, deglyhCG, asialohCG, hCGav and the closely related molecules hLH, hLH beta and hLH beta ef. The advent of monoclonal(More)
