Gluco- and mineralocorticoid receptors (GR and MR) act via common promoter elements but may exert different effects on gene regulation in various regions of the forebrain. In order to separately analyse the role of GR and MR in the regulation of neurotrophic factor genes and their receptors, we used adrenalectomy and subsequent hormone injections in the rat(More)
A strong neurotensin-like immunoreactivity (NT-like IR) was detected in the odontoblast cells of the rat teeth. 4 h after a partial pulpotomy performed in two maxillary molar teeth a decreased NT-like IR was observed in the odontoblast layer located at the vicinity of the lesion together with edema and nuclear pyknosis. NT-like IR became further decreased(More)
1. The mapping of glucocorticoid receptors (GR) in the rat central nervous system (CNS) has demonstrated their widespread presence in large numbers of nerve and glial cell populations also outside the classical stress regions. 2. The present paper summarizes the evidence that glucocorticoids via GR in the CNS can act as lifelong organizing signals from(More)
Microdensitometrical and stereological techniques were applied to study the effects of aging on the hippocampus of 3-, 6-, 12-, 18-, 24-, 30-, and 36-month-old male Brown Norway rats. Stereological analysis of basic fibroblast growth factor (bFGF) immunoreactive glial cells in the CA1 area showed an age-dependent decrease in the number of cells, starting at(More)
A detailed mapping of glucocorticoid receptor (GR) immunoreactivity (IR) in rat CNS was performed employing a mouse monoclonal antibody against rat liver GR. Subjective comparisons were made between the present results and the available data in the literature. A semiquantitation of GR immunostaining was found necessary and was obtained by microdensitometric(More)
Most speech enhancement techniques do not perform very well in correlated or colored noise, as they assume that noise and speech are not correlated. In this paper, we propose a method, based on spectral subtraction, which takes into account possible correlation between noise and speech. Objective measures showed that the proposed method outperformed the(More)
Figure 3.1: Plots of the values of power spectra of speech and noise along with the cross-term of speech and noise, over a 20 ms window. Figure 3.2: Plots of the values of power spectra of speech and noise along with the cross-term of speech and noise, over a 20 ms window.
Inhibitory effects of a fresh leaf juice of the Withania somnifera (W.s.) on the enzymes acetylcholinesterase (AChE; EC 3.1.17) and nicotinamide adenine dinucleotide diaphorase (NADPH-d) were studied in the mice brain using histochemical and biochemical approaches. The results obtained show significant reduction in the number of and reaction intensity in(More)
Sustained ventricular tachycardia (VT) is a life-threatening condition which requires immediate intervention. We report a case of unusual etiology of sustained VT in a 42-year-old male after a wasp bite in the absence of anaphylaxis. The patient was treated with amiodarone and improved within 48 h. Thus, wasp stings can lead to serious tachyarrhythmias(More)
