AIM:To investigate the role of exercise training the past 25 years on major physiological-psychological outcomes studied thus far in this patient ***:Pub Med, Medline Plus, the Cochrane Library, Web of Science, SportD iscus, Embase, Scorpus, and Google Scholar were searched from September to November 2013 to identify exercise training studies that used objective measurements of fitness and/or patient reported outcomes assessed pre and post-exercise training with statistical analyses performed in at least one of the following outcome measurements:Cardiorespiratory function, body composition, muscular strength, fatigue, depression, and overall quality of life. Five reviewers independently identified the studies that met the criteria for the review and discrepancies were resolved by consensus among all ***:Fifty-one studies were included in this review with 5 from the period between 1989-1999, 11 from 2000-2006, and 35 from 2007-2013. The evolution of study designs changed from aerobic only exercise training interventions(1989-1999), to a combination of aerobic and resistance training(2000-2006), to studies including an arm of resistance training or examining the effects of resistance training as the main mode of exercise(2007-2013). Overall, the benefits of exercise showed improvements in cardiorespiratory function, body composition, strength, and patient reported outcomes including fatigue, depression, and quality of ***:Exercise training appears to be safe for most breast cancer patients and improvements in physiological, psychological, and functional parameters can be attained with regular participation in moderate intensity exercise.

The axoneme of the human sperm has a very similar ultrastructure to motile cilia,the"9+2"structure,comprising nine peripheral double microtubules plus two central pairs(Nicastro et al.,2006;Ishikawa,2017).A proteomics analysis identified more than700 proteins exclusively in the sperm tail,and abnormal expression of related genes can cause male infertility with multiple morphological abnormalities of flagella(MMAF),including absent,coiled,short,and irregular-caliber flagella(Baker et al.,2013;Coutton et al.,2015).

BACKGROUND Evidence for exercise as an efficacious strategy to improve aerobic capacity of breast cancer survivors(BCS)has come largely from intervention studies conducted in laboratory *** is an increasing need to translate to community-type settings,but the efficacy of those interventions using gold standard evaluation is not *** To investigate whether similar improvement in aerobic capacity(maximal oxygen consumption[VO2])measured with gold standard testing can be achieved through a community-based setting in *** A peak cardiopulmonary exercise test(VO2peak),6-min walk test(6MWT),and timed up and go test(TUG)were assessed pre-and post-16 wk of progressive intensity aerobic and strength training exercise at a community *** The sample consisted of 31 early BCS(<1 year since treatment completion)and 15 controls(CTLs).Both groups significantly improved VO2peak(+1.2 mL/kg/min;P=0.030),6MWT(+35 meters;P<0.001),and TUG(-0.44 s;P<0.01)following *** groups improved peak cycling power during the cardiopulmonary exercise test with BCS improving by+10 watts more than the CTLs(P=0.020).Average exercise attendance was 71%(34 of 48 possible days),but compliant days averaged only 60%of total days for aerobic,and<40%for strength in both *** Community-based exercise programs can be an effective strategy to improve aerobic capacity and physical function for early-stage BCS but potentially not to the same extent observed in laboratory-based randomized controlled *** research is needed to explore barriers and facilitators of exercise engagement in community-based centers to maximize training benefits for adults with cancer.

以钛酸丁酯和硝酸银为前驱体,采用一步火焰辅助热解法制备了Ag_2O/TiO_2光催化剂并研究了样品在紫外-可见光照射下的光催化制氢性能。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)和紫外-可见漫反射吸收光谱(UV-Vis DRS)对样品进行了表征。XRD结果表明TiO_2均为锐钛矿晶型,Ag的引入对XRD结果无明显影响。SEM图显示未修饰的TiO_2是微球形貌,随着引入Ag含量的增加,微球减少直至消失。通过XPS分析和化学沉淀法表明样品中Ag的存在形式为Ag_2O。UV-Vis DRS测试发现引入Ag后提高了样品的光吸收。前驱体中Ag的量影响样品的光催化活性,最高的光催化制氢的活性可以达到相同条件下的P25的15倍。对光催化反应后的样品进行分析,认为在光催化过程中部分Ag_2O通过光生电子转化为Ag形成Ag/TiO_2,进一步提高光催化制氢活性。

We hypothesized that keeping one’s balance with eyes open in the dark is different and more difficult than eyes closed because the brain continues to process visual inputs in the dark when the eyes are open. On the other hand, when the eyes are closed, the visual system does not signal incongruent information with which the brain must compare the other sensory systems. A variety of cognitive (subtracting backwards by seven as quickly and accurately as possible) and support surface (fixed versus sway-referenced) conditions were used to probe the neural mechanisms underlying the sensory organization processes in healthy young adults. Peak-to-peak anteroposterior sway performance revealed two dissociated components of the treatment effects. The first component came from the visuospatial factor. Balance control during eye closure and eyes open in the dark were found to be similar but poorer than baseline condition (eyes open under typical lighting). The second component was the effect of task difficulty in which balance control in the sway-referenced condition was worse compared to fixed support during eye closure or eyes open in the dark. Analyses of the cognitive performance also revealed different underlying neural mechanisms of the experimental conditions. Subtraction speed under the fixed support surface condition was similar among all the conditions but was faster with eyes closed during the sway-referenced support surface condition. Accuracy was not affected among the visual and surface conditions. We conclude that sensory processing load with eyes closed is lower than eyes open in the dark, thereby allowing cognitive performance to proceed more efficiently. Performing a difficult subtraction task with eyes closed may afford a decrease in dual-task interference since similar brain areas, particularly the parietal region, are involved in both tasks. The results are discussed with reference to clinical application and spatial disorientation in aviation.
