INTRODUCTIONIn the past decades, the introduction of evidence-based medicine has prompted a paradigm shift in clinical practice. One of the important progress is involving health-care professionals in making informed decisions according to recommendations from evidence-based practice guidelines or other guidance documents （e.g., expert consensus statements） published by national and international authorities （e.g., the National Institute for Health and Care Excellence [NICE]; World Health Organization [WHO]） as well as professional bodies.

＜正＞This paper summaries a new method using multithreading and timed Petri Nets（TPN） in modeling and controlling a Parallel Operated System（POS） for Internet *** addition,the standard clock method is used to trigger the event in the TPN *** POS in the Laboratory Centre consists of a central controller,an automatic storage and retrieval system with input and output buffers（ASRS）,an automatic guided vehicle （AGV） and two Computer Numerical Controlled（CNC） machines with input and output buffers which are represented in respective *** Java programs,class members are built with attributes and methods to represent the individual components of the *** of these objects is implemented by making an instance of a respective class member and running it as one of the multiple threads. Coordinating actions between different objects is essential and it is often the case that these activities are time-related. Simulations of actions between these objects benefit by threading because they often model autonomous and interacting *** advantages of the proposed method of modeling the POS are that the simulation models can simultaneously provide control capabilities as well as implement the scheduling *** users can use the simulation models through the Interuet because the modeling method is relatively simple and the simulation is comparatively fast in Interuet applications.

This study aimed to investigate the association between atrophy in the prefrontal cortex with executive function and verbal fluency in elderly male and female patients poststroke. Thirty elderly female patients with non-aphasic ischemic stroke aged -〉 60 years and 30 age-matched non-aphasic male patients with ischemic stroke were recruited. Automatic magnetic resonance imaging segmentation was used to assess the volume of the whole prefrontal cortex, along with its subdivisions： anterior cingulate cortex, orbitofrontal cortex and dorsolateral prefrontal cortex. The Semantic Verbal Fluency Test was administered at 3 and 15 months poststroke. At 3 months poststroke, left dorsolateral prefrontal cortex volume was significantly correlated with Verbal Fluency Test score in female patients only （partial coefficient = 0.453, P = 0.045）, after controlling for age, education, diabetes, neurological deficit, white matter lesions volume, as well as the location and volume of infarcts. At 15 months poststroke, there remained a significant association between the left dorsolateral prefrontal cortex volume and Verbal Fluency Test （partial coefficient = 0.661, P = 0.001） and between the left prefrontal cortex volume and Verbal Fluency Test （partial coefficient = 0.573, P = 0.004） in female patients after the same adjustments. These findings indicate that atrophy of the left dorsolateral prefrontal cortex contributes to the impairment of verbal fluency in elderly female patients with stroke. Sex differences may be present in the neuropsychological mechanisms of verbal fluency impairment in patients with stroke.

Background: One of potentially dangerous problems for a human organism is the new strain of a virus of bird flu-A/H7N9. As it is regular mutation of bird flu virus, it obvious, that of antibacterial preparations is not efficient. Efficiency decreases when the number of agents with multiple stability to antimicrobic remedy vastly increases, the part of associate infections enlarges, and aggression of opportunistic pathogenic flora rises. This reduces the role of the preparations in prevention of epidemics. Therefore, the optimization of only etiotropic therapies does not fully solve the problem. In this connection natural preparations seem extremely promising which strengthen the functional condition of immune system and, thereby, activate protective forces of macroorganism. Objectives: One of such preparations is BAE Synergy Liquid, a natural mineral water which was underwent subtle energetic changes at the natural energetic deposit. Design: An estimation of protective efficiency of naturally modified mineral BAE SL water was performed on white outbred mice-males in models of H7N9 virus. The animals were monitored during 16 days after infection, and survived and fallen mice were counted daily. Results: The results revealed significant effect of the investigated preparation as possible prophylactic care and medical remedy to the mentioned virus. This means that one can be considered as potential effective remedy for human. Conclusions: As significant effect of the immune system resistance was revealed, the experimental model with studied naturally modified mineral water is potentially generalizable.
