In act theory, Pseudo injective acts and their generalizations are essential. As a result, the purpose of this work is to give generalization pseudo quasi principally specifically small acts. Besides, concept was presented, which can be employed later. If each S-monomorphism from M-cyclic sub-act M\textsubscript{S} N\textsubscript{S} extended S-homomorphism N\textsubscript{S}, An S-act called p...

Epinephrine or carbachol, alone or together with parathyroid hormone (PTH) or calcitonin, was added into the incubation of young rat tibia and cyclic AMP as well as cyclic GMP in the tissue was determined. Epinephrine induced a dose related and rapid increase of cyclic AMP probably through mechanism different from that of PTH or calcitonin. The effect of these hormones to increase cyclic AMP wa...

Cyclic 3’,5’-AMP stimulates the rate of tryptophanase synthesis in Escherichia coli treated with tris(hydroxymethyl)aminomethane and ethylenediaminetetraacetic acid and induced with tryptophan. A maximal effect occurs at 4 X low4 M cyclic 3’,5’-AMP and a half-maximal response at 1.5 X lo-4 M. The action of cyclic 3’,5’-AMP is specific for tryptophanase since the over-all rate of protein and RNA...

The purpose of this study was to examine the mechanisms underlying adrenergiccholinergic antagonism in ventricular myocardium. Myocardial contractility, cyclic adenosine monophosphate (AMP) levels, and cyclic guanosine monophosphate (GMP) levels were measured in isolated guinea pig ventricles after treatment with various inotropic agents given alone and simultaneously with acetylcholine. Acetyl...

The combined effects of cortisol and agents acting through a cyclic AMP-mediated mechanism have been studied in cultures of highly purified human peripheral lymphocytes. Incubation with prostaglandin E(1) (PGE(1)), dibutyryl cyclic AMP, or cortisol results in a concentration-dependent inhibition of [(3)H]-thymidine incorporation by both unstimulated and phytohemagglutinin (PHA)-stimulated lymph...

The level of cyclic AMP in primary cultures of bovine adrenal medulla cells is elevated by prostaglandin E1. Angiotensin II is commonly reported to act on receptors linked to phosphoinositide metabolism or to inhibition of adenylate cyclase. We have investigated the effect of angiotensin II on prostaglandin E1-stimulated cyclic AMP levels in these primary cultures. Rather than reducing cyclic A...

Cyclic N-substituted glycines oligomers, also known as cyclic peptoids, constitute a promising class of novel peptidomimetics, capable simulating bioactive effectors with enhanced proteolytical stability and cell permeability crucial bonuses. The macrocyclic constraint, essential for the induction stable secondary structures, determines biomimetic potential such molecules, which act antimicrobi...
