1. 4,6-Dibromo-3-hydroxycarbazole (DBHC) was synthesized as an analogue of bromoeudistomin D (BED), a powerful Ca2+ releaser, and its pharmacological properties were examined. 2. In Ca2+ electrode experiments, DBHC (100 microM) markedly inhibited Ca2+ release from the heavy fraction of sarcoplasmic reticulum (HSR) induced by caffeine (1 mM) and BED (10 microM). 3. DBHC (0.1 to 100 microM) inhib...

The vasodilator response to bradykinin (BK) appears to be mediated by a number of different endothelium-derived relaxing factors (EDRFs). The EDRFs mediating the response depend on the species and vascular bed studied. The mechanism by which BK dilates the hindlimb vascular bed was investigated in the anesthetized rat. BK produced dose-dependent increases hindlimb blood flow. The NOS antagonist...

Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...

Bed bugs appear to be feared more than vector insects and other household pests. The reasons for this exaggerated fear are not fully understood. One hypothesis is that the folk knowledge on recognising and controlling bed bugs decreased as bed bugs became rarer in the 1960s and led to irrational perceptions. Here, we examine people's ability to recognise a bed bug and their response what to do ...

Respiratory disorders that present in the newborn period may result from structural, functional, or acquired mechanisms that limit gas exchange between the airspace and vascular bed. Exciting new imaging, gene sequencing, mass spectrometry, and molecular and cell-based techniques are enhancing our understanding of mechanisms of disease; highlighting the complexity of interactions between genes,...

in this paper the effectiveness combination of bed sill and collar in reduction of local scour depth at cylindrical piers under clear water flow condition was investigated (v/vc=0.9). in the first of experiments, the bed sill was located in downstream and different distances from the piers. results indicated that minimum distance of the bed sill from the piers in downstream has maximum reductio...

In this paper, we briefly review recent results by the authors on the formulation of the equations of motion of closed-chain mechanisms and the development of PD control strategies with guaranteed Lyapunov asymptotic stability. We then introduce and derive the equations of motion of the Rice Planar Delta Robot which was designed and built at Rice University as a test bed to perform control expe...

Relief of angina by nitroglycerine has been attributed to two possible mechanisms: (1) Increase in myocardial blood supply by direct acton of the drug on the coronary arteries. (2) Reduction in myocardial oxygen demand by action of the drug on the systemic circulation. Sublingual application of nitroglycerin in previous studies did not allow the ruling out of the operation of either or both mec...

Aim. The purpose of the current research is to measure the level of aggression among females diagnosed with BED and individuals displaying no eating or mental disorders, and to make a comparative study of the aforementioned variable. Methods. The main research variables were measured using a psychometric method the Revised Psychological Inventory of Aggression Syndrome by Gaś (Polish: IPSA-II)....
