Repair and remodeling processes initiated by arterial injury are thought to be critical in the pathogenesis of important vascular disorders. However, how these processes are related to specific types of injury is not well defined. Consequently, we compared arterial responses to several types of injury. Segments of rabbit carotid arteries were injured by intraluminal passage of an inflated embol...

Histological analysis was carried out on ovarian development in the picnic seabream, Acanthopagrus berda (Forsskål 1775) caught estuarine waters of Calicut, Kerala, India from January to December 2016. Four developmental phases oocyte were identified viz., oogonia proliferation and transformation into primary oocyte, growth phase, secondary phase maturation these are similar those described for...

Intracellular Ca(2+) oscillations at fertilization are responsible for triggering egg activation. The aim of this study was to examine the effect of the age of the oocyte donor and in-vitro maturation on the generation of Ca(2+) transients at fertilization. The results show that <10% of in-vivo and in-vitro matured oocytes from 19-day old mice develop to the blastocyst stage in vitro. In contra...

Whether or not steady-state topography and denudation are probable states depends on the timescale of system response to tectonic and climatic perturbations relative to the frequency of those perturbations. This paper presents analytical derivations of algebraic relations for the response time of detachment-limited fluvial bedrock channel systems both to tectonic and climatic perturbations. Det...

Nitric oxide produced by inducible nitric oxide synthase (iNOS) regulates sepsis-induced hypotension. During septic shock, interleukin (IL)-1β is synthesized in endothelial cells and smooth muscle cells by endotoxin. Ethanol (EtOH) suppresses endotoxin-induced hypotension. The present study aimed to elucidate the effect of EtOH on gradual relaxation and iNOS expression induced by IL-1β in isola...

Cytokeratins have previously been shown to exist in the Xenopus oocyte cortex. Using three monoclonal antibodies against cytokeratins, we follow the appearance of cytokeratin-containing filaments, and their changes in distribution during oocyte differentiation and maturation. Cytokeratin-containing filaments are shown to change dramatically in distribution in the oocyte during its ontogeny.
