BACKGROUND Electroacupuncture (EA) is used clinically for the treatment of constipation. Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in colonic motility; however it is unknown whether alterations in colonic 5-HT are associated with EA. In this study, the effect and mechanism of EA at acupuncture points LI11 and ST37 were examined using a cold saline-induced rat model of consti...

TOEFL iBT has turned recently heads to the impacts language tests can have on language learning. Since error analysis-based instruction has gained a new life with the advent of the computer analysis of the learner’s language, the researchers of this study embarked on examining a sample of integrated and independent writing tasks of 45 Iranian TOEFL iBT candidates in order to identify and classi...

In practical applications evaluating a fitness function is frequently subject to noise, i. e., the “true fitness” is disturbed by some random variations. Evolutionary algorithms (EAs) are often successfully applied to noisy problems, where they have turned out to be particularly robust. Theoretical results on the behavior of EAs for noisy functions are comparatively very rare, especially for di...

During robot-assisted laparoscopic prostatectomy, specific physiological conditions such as carbon dioxide insufflation and the steep Trendelenburg position can alter the cardiac workload and cerebral hemodynamics. Inadequate arterial blood pressure is associated with hypoperfusion, organ damage, and poor outcomes. Dynamic arterial elastance (Ea) has been proposed to be a useful index of fluid ...

Inflammatory bowel disease is a chronic colonic inflammation that displays symptoms like diarrhea and weight loss. Acupuncture has been widely accepted by Western countries for the treatment of pain. Here, we analyzed efficacy and mechanism of electroacupuncture (EA) on trinitrobenzene sulfonic acid- (TNBS-) induced colitis in mice. Mice were intrarectally administered with 250 mg/kg TNBS and e...

Background. EA therapy is a traditional therapeutic approach for alleviation of cerebral I/R-induced brain injury. We investigated the effect of EA on MCAO rat model to examine the mechanism of apoptosis in the rat hippocampus. Methods. 200 male Sprague-Dawley rats were randomly divided into sham, I/R, EA, ERK inhibitor (PD), and ERK inhibitor+EA (PD+EA) groups. Each group was subdivided into 5...

OBJECTIVES To assess the effectiveness and safety of electroacupuncture (EA) combined with rehabilitation therapy (RT) and/or conventional drugs (CD) for improving poststroke motor dysfunction (PSMD). DESIGN Systematic review and meta-analysis. METHODS The China National Knowledge Infrastructure, Chinese Biological Medicine Database, Chinese Scientific Journal Database, Cochrane Library, Me...

AbstractWe study evolutionary algorithms in a dynamic setting, where for each generation different fitness function is chosen, and selection performed with respect to the current function. Specifically, we consider Dynamic BinVal, which functions given by linear but order of bits randomly permuted. For \((1 + 1)\)-EA it was known that there an efficiency threshold \(c_0\) mutation parameter, at...

The search ability of an Evolutionary Algorithm (EA) depends on the variation among the individuals in the population [3, 4, 8]. Maintaining an optimal level of diversity in the EA population is imperative to ensure that progress of the EA search is unhindered by premature convergence to suboptimal solutions. Clearer understanding of the concept of population diversity, in the context of evolut...
