Considering the importance of sufficient physical activity in military personnel, this study was designed to determine the levels of this activity and factors influencing it among personnel of a military center in Iran. This cross-sectional method on 191 individuals randomly selected from entire staff working in a military center. A self – report valid and reliable questionnaire was applied t...
It has been shown that the hyperpolarization-activated current “if” that is blocked by 2 mM Cs+ plays a minor role on pacemaker activity of the center and a major role on activity of the periphery of rabbit intact sino-atrial node. On the other hand some investigations showed that if the atrial muscle, surrounding the sino-atrial node, is cut away there is a shift in leading pacemaker site from...
INTRODUCTION Surveillance systems for health status and behaviors of populations are fundamental for planning, implementing, and monitoring preventive interventions. In 2006, the Italian Ministry of Health provided funding to the National Institute of Public Health to develop an ongoing surveillance system for adult behavioral risk factors. We describe the main features of the system (known as ...
Winter snowfall and its temporal variability are important factors in the development of water management strategies for snow-dominated regions. For example, mountain regions of Europe rely on snow for recreation, and on snowmelt for water supply and hydropower. It is still unclear whether in these regions the snow regime is undergoing any major significant change. Moreover, snow interannual va...
The mammalian sino-atrial node is not a uniform tissue in histological and electrophysiological terms. The differences in ionic currents underlying the regional differences in electrial activity are only just beginning to be understood. One of the ionic currents it is thought to play a role in the center of sino-atrial node for action potential upstroke should be transient Ca+2 current ...
This report describes a draft genome sequence of Lactobacillus crispatus 2029. The reads generated by the Ion Torrent PGM were assembled into contigs with a total size of 2.2 Mb. The data were annotated using the NCBI GenBank and RAST servers. A comparison with the reference strain revealed specific features of the genome.
