The duration of action of single oral doses of 80 and 160 mg of propranolol during acute and sustained therapy was studied in nine patients with stable, exercise-induced angina pectoris. Plasma propranolol levels peaked 2 hours after both doses during acute and sustained therapy, but there were wide variations between individuals in plasma concentration with both dosage schedules. Plasma half-l...

abstract background and objective: it has been shown that oxidative stress increases in diabetes and it has an important role in its development and subsequent complications. thus, the aim of this study was to investigate the effect of acute resistance exercise on oxidative stress in skeletal muscle and cardiac tissues of streptozotocin-induced diabetic rats. materials and methods: twenty male ...

Given a collection of points in a multi-dimensional space, we consider the problem of nding the set of all possible Maximal Hyper-Rectangle (MHR), deened to be hyper-rectangles that are empty and have at least a point bounding each of its surfaces. It is easy to see that there are enormous number of such MHRs in a given instance, and most of the time, applications require only to nd the \larges...

This paper proposes a cell-numbering plan for mobile stations to handoff seamlessly to the cells in a wireless Asynchronous Transfer Mode (ATM) network. It also proposes a minimum-hop rerouting (MHR) method to perform the rerouting of user connections during the handoff. The cell-numbering plan assigns each cell an integer from 1 to 5, ensuring that neighboring cells will have different numbers...

Experimental studies were carried out with a laboratory-scale biotrickling filter to treat a gaseous stream contaminated with benzene, toluene and xylene (BTX) operated in a continuous mode. The biotrickling filter initially acclimatised with toluene was used to treat BTX compound individually at loading rates ranging from 7.2 g/mhr to 62.2 g/mhr, operated in a sequential mode. The results show...

Evaluation of The Acute Hormonal Responses To Concentric, Eccentric And Concentric_ Eccentric Muscle Actions in Healthy Young Men Introduction: Resistance exercise is a potent stimulus for acute increase in the concentrations of circulating hormones such as Growth Hormone (GH) and Testosterone. Conventional resistance exercise is performed using sequential concentric (CON) and eccentric (EC...

The popularity of using phase change materials (PCMs) for heat storage and recovery metal hydrides’ reaction has grown tremendously. However, a fundamental study the coupling such system with low-temperature PEM (polymer electrolyte membrane) fuel cell is still lacking. This work presents numerical investigation dehydrogenation performance hydride reactor (MHR)-PCM coupled cell. It shown that t...

The embryonic modal value of heart rate (MHR) differs between broiler and White Leghorn chickens, but the initial development of cholinergic chronotropic control of embryonic heart rate (HR) does not. Thus, we hypothesized that hatchling MHR should also differ between broiler and White Leghorn strains, while the development of a physiological regulation, such as the endothermic HR response, sho...

The objective of this study was the assessment of heart-rate (HR) dynamics with linear and nonlinear methods during episodes of mechanical ventilation and acute anoxia in rats. Namely, to assess whether linear and nonlinear HR analysis was able to discriminate acute anoxia from baseline in rats and if this was consistent with human foetal and adult studies. Five HR segments of 1 min duration, d...
