Epilepsy is one of the most prevalent neurological disorders with no age, racial, social class, and neither national nor geographic boundaries. There are 50 million sufferers in the world today with 2.4 million new cases occur each year. Electroencephalogram (EEG) has become a traditional procedure to investigate abnormal functioning of brain activity. Epileptic EEG is usually characterized by short transients and sharp waves as spikes. Identification of such event splays a crucial role in epilepsy diagnosis and treatment. The present study proposes a method to detect three epileptic spike types in EEG recordings based mainly on Template Matching Algorithm including multiple signal-processing approaches. The method was applied to real clinical EEG data of epileptic patients and evaluated according to sensitivity, specificity, selectivity and average detection rate. The promising results illuminate that hybrid processing approaches in temporal, frequency and spatial domains can be a real solution to identify fast EEG transients.

An efficient and facile approach for tetrachlorosilane as an in situ mediated transformation via a one-pot, synthesis of vicinal bromoazides through the generation of BrN3 from azidochlorosilane and N-bromosuccinimide in acetonitrile as solvent at ambient temperature is achieved. This catalytic process represents a highly regioselective and high yielding method for the synthesis of 1,2- bromoazides. Thiamine pyrophosphate （TPP） riboswitches regulate essential genes in bacteria by changing conformation upon binding intracellular TPP. Molecular docking studies are conducted to understand the orientation and the interaction of each synthesized molecules with TPP riboswitches, 2016 Chinese Chemical Society and Institute of Materia Medica, Chinese Academv of Medical Sciences.

一带一路”倡议是BRI自2013年初中华人民共和国主席习近平先生宣布以来最热门的话题之一。它吸引了广泛的研究人员和政策制定者的关注由于其雄心勃勃和广泛的目标。该倡议的主要目标是在中国与亚洲,欧洲和非洲的不同国家之间建立一体化市场。因此,为了实现这一目标,正在建立除贸易路线之外的各种基础设施和能源项目,以便在各大洲之间获得更好和更安全的连接。埃及参与了 BRI实施计划下不同部门的许多项目。本文讨论了埃及参与该计划,更加关注海事基础设施项目。关于正在埃及港口实施的BRI基础设施改进,本文使用随机效应模型应用引力模型。该论文的主题是证明基础设施改善项目具有影响力,是促进埃及贸易特别是出口的关键角色之一。除了预测埃及出口对参与研究的国家的趋势和潜在影响。本文利用面板数据分析,因为它具有很强的检测变量影响的能力。除埃及外,该研究区还包括47个国家作为这些国家的出口国。该研究包括从2013年至2017年开始的一段时间。估计结果表明,港口的基础设施改善对出口量产生了重大影响。除了残余的结果之外,埃及的出口往往更多地涉及BRI所涉及的国家。

AIM To investigate the incidence of achalasia in Algeria and to determine its clinical and para-clinical profile. To evaluate the impact of continuing medical education(CME) on the incidence of this *** From 1990 to 2014, 1256 patients with achalasia were enrolled in this prospective study. A campaign of CME on diagnosis involving different regions of the country was conducted between 1999 and 2003. Annual incidence and prevalence were calculated by relating the number of diagnosed cases to 105 inhabitants. Each patient completed a standardized questionnaire, and underwent upper endoscopy, barium swallow and esophageal manometry. We systematically looked for Allgrove syndrome and familial *** The mean annual incidence raised from 0.04(95%CI: 0.028-0.052) during the 1990 s to 0.27/105 inhabitants/year(95%CI: 0.215-0.321) during the 2000 s. The incidence of the disease was two and half times higher in the north and the center compared to the south of the country. One-hundred-and-twenty-nine(10%) were children and 97(7.7%) had Allgrove syndrome. Familial achalasia was noted in 18 different families. Patients had dysphagia(99%), regurgitation(83%), chest pain(51%), heartburn 24.5% and weight loss(70%). The lower esophageal sphincter was hypertensive in 53% and hypotensive in 0.6%.CONCLUSION The mean incidence of achalasia in Algeria is at least 0.27/105 inhabitants. A good impact on the incidence of CME was noted. A gradient of incidence between different regions of the country was found. This variability is probably related to genetic and environmental factors. The discovery of an infantile achalasia must lead to looking for Allgrove syndrome and similar cases in the family.
