introduction: to study the effect of gallic acid (ga) on hippocampal long-term potentiation (ltp) and histological changes in animal model of alzheimer disease (ad) induced by betaamyloid (aβ). methods: sixty-four adult male wistar rats (300±20 g) were divided into 8 groups: 1) control (cont); 2) ad; 3) sham; 4-7) ad+ga (50, 100, and 200 mg/kg for 10 days, orally) or vehicle, 8) cont+ga100, aβ ...

achillea millefolium belonging to the astreaceae family is an endangered medicinal plant of jordan and of its neighboring countries. as an alternative to seed propagation, an efficient micropropagation of a. millefolium and its subsequent rooting were developed as an option for its in vitro conservation. a maximum of 5.9 shoots per microshoot were obtained on murashige and skoog agar medium sup...

this study identifies and compares the antecedent of nigerian students’ perception on business social responsibility. part of its objectives is to examine the perception of business students in terms of importance of business social responsibility with respect to profitability, and the effectiveness of social responsibility in both long and short terms. the study reviews the related literature ...

This study uses the example of the tennis serve to investigate the nature and role of long-term memory in skilled athletic performance. Information processing linked with complex movements has always been notoriously difficult to investigate. However, a new experimental method revealed that athletic expertise was characterized by well-integrated networks of so-called basic action concepts (BACs...

The reduced verbal long-term memory capacities often reported in dyslexics are generally interpreted as a consequence of their deficit in phonological coding.The present study was aimed at evaluating whether the learning deficit exhibited by dyslexics was restricted only to the verbal component of the long-term memory abilities or also involved visual-object and visual-spatial domain. A further...

BACKGROUND A specific measurement issue often occurs in cohort studies with long-term follow-up: the substitution of the classic instruments used to assess one or several factors or outcomes studied by new, more reliable, more accurate or more convenient instruments. This study aimed to compare three techniques to deal with this issue when the substituted instrument is a questionnaire measuring...

Previous work has shown that joint modeling of two Natural Language Processing (NLP) tasks are effective for achieving better performances for both tasks. Lots of task-specific joint models are proposed. This paper proposes a Hierarchical Long Short-Term Memory (HLSTM) model and some its variants for modeling two tasks jointly. The models are flexible for modeling different types of combination...

Modeling temporal sequences plays a fundamental role in various modern applications and has drawn more and more attentions in the machine learning community. Among those efforts on improving the capability to represent temporal data, the Long Short-Term Memory (LSTM) has achieved great success in many areas. Although the LSTM can capture long-range dependency in the time domain, it does not exp...

the median overall survival in glioblastoma multiforme is usually less than one year. long-term survival is rare and is seen in only 3%-6% of gbm patients. the present study reports the characteristics and treatment outcomes of six cases of glioblastoma multiforme with long-term survival. a literature review is also presented. between 1990 and 2008, 217 glioblastoma multiforme patients have bee...
