objective: strong evidence indicate that activity of glucocorticoid receptors is necessary for emotional memory processess and these effects probably are mediated by hipppocampal opioid receptors. the aim of this study was to test whether there were any interaction between glucocorticoid and hippocampal opiate receptors on consolidtaion and retrieval of spatial memory. materials and methods: in...

bstract—Chronic stress and spatial training have been proosed to affect hippocampal structure and function in oppoite ways. Previous morphological studies that addressed tructural changes after chronic restraint stress and spatial raining were based on two-dimensional morphometry which oes not allow a complete morphometric characterisation of ynaptic features. Here, for the first time in such s...

OBJECTIVES To determine the effects of training in swimming and water safety on young preschool-children's ability to recover safely from a simulated episode of falling into a swimming pool. DESIGN Randomized trial of 12 or eight weeks' duration water safety and swimming lessons for children 24 to 42 months old. OUTCOME MEASURES Swimming ability, deck behavior, water recovery, and swimming ...

Components of the chiral vector of carbon nanotubes have been examined in role of structural descriptors. Two-variable models of water solubility and octanol water partition coefficient calculated with components of the chiral vectors have quite good statistical characteristics. These are in case of the water solubility: n=8, r(2)=0.99998, s=0.05338, F=126,611 (training set); n=8, r(2)=0.9999, ...

We implemented a novel approach to score water mediation and displacement in the protein-ligand docking program GOLD. The method allows water molecules to switch on and off and to rotate around their three principal axes. A constant penalty, sigma(p), representing the loss of rigid-body entropy, is added for water molecules that are switched on, hence rewarding water displacement. We tested the...

We have studied the influence of pre-training psychological stress on the expression of c-fos mRNA following long-term spatial memory retrieval. Rats were trained to learn the location of a hidden escape platform in the radial-arm water maze, and then their memory for the platform location was assessed 24 h later. Rat brains were extracted 30 min after the 24-h memory test trial for analysis of...

A series of experiments was performed to obtain direct estimates of absolute distance under water, and to determine if judgment accuracy can be improved through training. Distance was underor over-estimated, depending to a large extent on water turbidity, which increased the magnitude of judgments. Also, whereas the power-function exponent for distance estimation in air was slightly less than 1...

The University of Kentucky College of Dentistry (UKCD) established an implant training program that provides training in the use of a single implant system, evidence-based diagnostic and treatment protocols (standardized work practices), and a total quality management system (Implant Quality Assurance Program). The aim of this study was to assess the programmatic effectiveness of the UKCD impla...

We evaluate the short-term impact of financial support to smallholder farmers and training program to married women in two regions of Ethiopia. Using household-level panel data from the World Bank collected in 2010-2012, the combined Difference-In-Difference (DID) and matching methods are applied. The three main findings emerge from the analysis shows that first; the program seems to improve ru...

BACKGROUND Gait and balance impairments may increase the risk of falls, the leading cause of accidental death in the elderly population. Fall-related injuries constitute a serious public health problem associated with high costs for society as well as human suffering. A rapid step is the most important protective postural strategy, acting to recover equilibrium and prevent a fall from initiatin...
