introduction: nowadays opioids are gaining acceptance for the management of moderate to severe and chronic pain. in addition, a number of studies have shown that plasma levels of β-endorphin (βep) in exercise trained are higher than sedentary rats. in our study we assume that exercise training can reduce pain after withdrawal syndrome in morphine-dependent rats. methods: male wistar rats (250±2...

Concentrated suspensions of swimming microorganisms and other forms of active matter are known to display complex, self-organized spatiotemporal patterns on scales that are large compared with those of the individual motile units. Despite intensive experimental and theoretical study, it has remained unclear the extent to which the hydrodynamic flows generated by swimming cells, rather than pure...

1. The differentiation of myotomal muscles in the brook trout (Salvelinus fontinalis Mitchill) has been investigated using p-phenylene diamine stained semi-thin sections and cytochemical and quantitative determinations of enzyme activities. 2. Evidence is presented that the range of fibre size in white muscle represents stages in growth rather than distinct fibre types. 3. Electromyography show...

An autonomous underwater vehicle (AUV) with less noise and vortices as well as efficient power consumption, is pursued in this research by inspiration of shark swimming. Design, hydrodynamic analysis, modeling, fabrication, navigation, and control of this novel AUV is the main goal of this research. Detailed explanation of the test and experiment with a brief overview on fabrication are provide...

Keywords: Micro-swimming Micro-flows Resistive force theory Hydrodynamic interaction Bio-inspired robots Surrogate models a b s t r a c t Research on micro-swimming robots without tether is growing fast owing to their potential impact on minimally invasive medical procedures. Candidate propulsion mechanisms of robots are vastly based on microorganisms with rotating helical tails. For design of ...

Ireland has one of the highest prevalence rates of asthma in the world with 1 in 7 children and 1 in 10 adults affected. 1 Its symptoms are characterised by either cough, feeling of chest tightness or wheezing which can be episodic or triggered by colds, sudden change in temperature, exercise or exposure to environmental allergens. Although some exercises can exacerbate its symptoms, swimming i...

orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. therefore, this study attempts to compare some yield and fruit properties of ...

background: there are challenges ahead of short-term hospitalization of low-risk patients hospitalized only for monitoring of severe disease who may die soon after admission. the purpose of this study was to suggest strategies for the management of icu stay lengths and to ensure optimal use of icu resources.   methods: the study was conducted retrospectively on 246 patients admitted to 9 genera...

patients and methods a cross-sectional study was conducted at icus of imam-reza and vali-asr hospitals, birjand, iran. sampling was done through a census in which 53 icu nurses participated. descriptive statistics, kolmogorov-smirnov test, mann-whitney u tests and kendall's correlation coefficient were used to analyze the data. results a total of 53 nurses participated in this study. most of th...
