The subventricular zone (SVZ) provides a constant supply of new neurons to the olfactory bulb (OB). Different studies have investigated the role of olfactory sensory input to neural precursor cell (NPC) turnover in the SVZ but it was not addressed if a reduced demand specifically for periglomerular neurons impacts on NPC-traits in the rostral migratory(More)
Neomycin, a selective inhibitor of the phosphoinositide metabolism, depending on its concentration and the incubation time, depressed the K+-contractures and contractions of m. sartorius R. ridibunda caused by a single or a tetanic electrostimulation. In the experiments on m. rectus abdominis, neomycin inhibited the Ach- and oubaine contractures but not the(More)
Computer " reading " of natural languages is a growing research topic with numerous applications, ranging from areas of artificial intelligence to linguistics. A successful " reading " of natural languages can be interpreted in two ways: 1) extracting facts out of a passage and 2) capturing " meaning " of a text. We focus on the latter interpretation,(More)
The glycerol was shown to lead to a considerable though transient increase in the contractile amplitude of the m. sartorius. Prolonged incubation of the muscle in the Ringer and Ca-free solutions in presence of glycerol led to a decrease in the response following potentiation. The potentiation due to glycerol seems to be caused by Ca2+ release which, in its(More)
The potentiation of contractile responses during prolonged incubation of frog sartorius muscles in a conventional Ringer solution and in a calcium-free Ringer solution which contained 400 mM of urea, acetamide or ethylene glycol was observed when stimulation with single electric impulses and with caffeine was carried out. When the muscles were exposed to a(More)
A study was made of the influence of glycerol loading on contraction responses of the m. sartorius upon stimulation in normal and calcium-free Reinger solutions by caffeine, tetanic electrostimulation and single electric impulses. It was determined that in the glycerol medium each type of stimulation caused contractility potentiation. Ca2+-ions proved to(More)
