We describe the presence of c-kit positive interstitial cells of Cajal-like (ICCs-like) in the walls of the urinary bladders of children. An immunohistochemical study of specimens, obtained at autopsy from either the trigonum (Group A) or the corpus (Group B), was performed using antibodies against c-kit (CD 117). Histological morphometry of the immunoexpression of c-kit positive ICCs-like was performed by means of image analysis system...

The 2-amino-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole set are well known compounds with interesting in vitro and in vivo anti-cancer profiles. The aim of this study was an in vitro evaluation of the anti-cancer activity of a new synthesized aminothiadiazole derivative 2-(3-chlorophenyloamino)-5-(2,4-dihydroxyphenyl)- -1,3,4-thiadiazole 4ClABT...

We have previously reported on hypoxia/reoxygenation-induced premature senescence in neonatal rat cardiomyocytes. In this research, we investigated the effects of p21WAF1 (p21) in hypoxia/reoxygenation-induced senescence, using H9c2 cells. A plasmid overexpressing wild type p21WAF1 and a plasmid expressing small hairpin RNA (shRNA) targeting p21WAF1 were constructed, and transfected into H9c2 cells to control the p21 expression...

The prognosis in prostate cancer depends on several clinical-morphological factors, such as Gleason score, pTNM and preoperative PSA level. Reliable biological markers are being sought to supplement clinicalmorphological data in order to better predict prognosis and to select an individualized therapeutic option...

Mammalian aquaporins (AQPs) are a family of at least 13 integral membrane proteins expressed in various epithelia, where they function as channels to permeate water and small solutes. AQP5 is widely expressed in the exocrine gland where it is likely involved in providing an appropriate amount of fluid to be secreted with granular contents...

Ischemic-reperfusion injury (IRI) is defined as tissue damage, organ dysfunction or failure developed in the course of inflammatory response following ischemia and reperfusion (IR). Abdominal aortic aneurysm (AAA) repair required IR of distal parts of the body carries a risk of organ injury and postoperative mortality of between 4% and 12%...

Idiopathic nephrotic syndrome (INS) in children is most commonly caused by primary glomerulopathies. Morphological lesions observed in INS might be secondary to inflammatory factors of mainly extra-renal origin. The vascular endothelial growth factor (VEGF) family is regarded as playing a crucial role in this pathomechanism...

In the pathogenesis of chronic otitis media (COM), much attention is paid to the molecular mechanisms of local inflammatory reactions in which mast cells (MCs) may be involved due to their role not only in allergic but also inflammatory processes. The aim of this study was to assess the density of mast cells in chronic otitis media in relationship to different clinical courses of COM, bacterial infections and types of disease....

The endemic Rhodanian percid Zingel asper (Linnaeus, 1758), is usually found throughout the Rhône basin, but this fish is now in sharp decline. Understanding its reproductive physiology is important so as to be able to artificially control its reproduction with a view to re-introducing it....

Angiotensin II (AngII) is the biologically active peptide of the renin-angiotensin system (RAS). Tissue-based, local RAS has been identified in the prostate, testis, epididymis and coagulating glands...
