background management of urethral stricture has evolved over the years with better understanding of the pathology, advancement in imaging, and introduction of several techniques of urethral reconstruction. in sub-saharan africa, advancement in management of urethral stricture may not be comparable with what obtained in most developed nations because of problems like late presentation and persis...

Clinical presentations of dyspnea, pedal edema, enlarged liver, and jugular venous distention may require differentiating constrictive pericardial disease (CPD) from restrictive cardiomyopathy (RCM). Differentiation the pathophysiology is paramount importance to invasive cardiologist because they are often called sort out a confusing clinical picture. The surgical treatment constriction not onl...

In this paper we numerically investigate the breakup dynamics of droplets in an emulsion flowing a tapered microchannel with narrow constriction. The mesoscale approach for multicomponent fluids near contact interactions is shown to capture deformation and interacting within constriction, agreement experimental evidences. addition, it permits detail hydrodynamic phenomena occurring during stage...

abstract background: it has been demonstrated that noscapine, an antitussive opioid alkaloid, could antagonize bradykinin- induced responses such as bradykinin effects in guinea-pig ileum, cough induced by bradykinin receptor agonist and angiotensin converting enzyme inhibitors, and brain damage after brain edema both in neonatal rat model and in patients with stroke. in the present study, the ...

The mechanisms mediating renal microvascular constriction induced by angiotensin II (Ang II) and endothelin (ET) have not been fully established. In the present study, we have determined the effects of isradipine, a dihydropyridine calcium antagonist, on Ang II- or ET-induced constriction of afferent arterioles (AAs) and efferent arterioles (EAs) using the isolated perfused hydronephrotic kidne...

To investigate whether exercise training can reverse age-related impairment of myogenic vasoconstriction in skeletal muscle arterioles, young (4 mo) and old (22 mo) male Fischer 344 rats were randomly assigned to either sedentary or exercise-trained groups. The roles of the endothelium and Kv1 channels in age- and exercise training-induced adaptations of myogenic responses were assessed through...

The terms ego constriction, ego inhibition, and ego restriction have not been clearly differentiated in their usage in the literature. In this paper a rationale for "ego constriction" as an entity distinct from both ego inhibition and ego restriction is given, despite its clear similarities to each. In a person with an ego inhibition, the ego inhibits a part of its own functioning because a par...
