脑卒中已经成为我国居民的第一位死亡原因,每年死于脑卒中患者约196万、每21秒就有一人死于卒中、每12秒钟就有一人发生卒中、每年新发卒中患者约270万、每年8.7%的速度增加。脑卒中成为导致中国人死亡的首位原因,超过了缺血性心脏病和COPD。急性脑血管栓塞病情十分危急且凶险,有高死亡率及高致残率等特点。
Purpose: This study aims to identify optimal body size and limb segment length ratios associated with 100-m personal-best (PB) swim speeds in children and adolescents. Methods: Fifty national-standar...
The aims of the present study were to examine (i) the age of peak swim speed and (ii) the sex difference in peak swim times in 200m and 400m medley versus freestyle. Swim times and ages of 5,524 swimm...
We investigated the change in body composition and hydration status in one male ultra-endurance swimmer during a 24-hour swim. Body mass, percent body fat and skeletal muscle mass using the anthropome...
Both in swimming and triathlon, depending on the event, the athletes have to swim the same distance (1500 meters) but the goal is different. In swimming, the goal is to be the fastest (winning the rac...
Underwater swimming is a unique exercise and its fitness is not accomplished by other types of training. This study compared high intensity intermittent fin-swim training (HIIT) with moderate intensit...
The number of bovine spermatozoa separated in a swim-up procedure was quantified using an electronic cell counter. In an initial test of the swim-up procedure, non-frozen sperm samples with differen...
Tyrosine phosphorylated proteins recently have been found in mouse and human spermatozoa. Our objectives were to (1) determine if domestic cat spermatozoa also express tyrosine phosphorylated pro...
In this study, the authors evaluated the morphology pattern and motion characteristics of human spermatozoa before and after swim-up separation. Samples were divided into two, morphologically diff...
Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (grea...
The objective of this study was to compare the efficacy of 2 dextran/swim-up media to increase the sperm quality parameters and the maintenance of these parameters at 15°C and 30°C over 6 hours. A...
The origin and the meaning of DNA fragmentation in ejaculated human spermatozoa are not yet clear, although some hypotheses have been proposed. In the present study, we used investigated sperm DNA fra...
Toxicological and epidemiological studies have investigated several factors that are believed to induce cytogenetic damage in human sperm cells in an effort to estimate heritable risk to future gene...
