Sport participation and vigilance in children:Influence of different sport expertise

Purpose： The present study aimed to investigate the relationship between different types of sport expertise （externally-paced vs. self-paced sports） and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. Methods： Three groups of children （11.0 ± 0.2 years） differentiated in terms of their regular sport participation （football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20） took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task （PVT） to evaluate their vigilance performance under 2 conditions of velocity demands （normal vs. speed）. Results： The results revealed that both groups of sport practitioners had higher cardiovascular fitness than non-athlete controls. In contrast, no significant differences in the performance PVT were found between track and field athletes and controls. Crucially, football players showed better performance in the PVT than track and field athletes and controls. These between-group differences were not modulated by the speed demands of the task. Conclusion： The major novel finding of this research points to a positive relationship between sport participation and vigilance performance during childhood. We discuss our results in terms of the different hypotheses put forward in the literature to explain the relationship between regular exercise and cognitive fimctioning： the ＂cardiovascular fitness＂ and the ＂cognitive component skills＂ hypotheses.2018 Published by Elsevier B.V. on behalf of Shanghai University of Sport.

Left atrial dysfunction in elderly patients with patent foramen ovale and atrial septal aneurysm

Objective Recently it has been suggested that, in patients with large patent foramen ovale （PFO） and atrial septal aneurysms （ASA）, a certain amount of left atrial （LA） dysfunction may be active as an alternate mechanism promoting arterial embolism. Following this hypothesis, elderly patients, being more susceptible to atrial chambers stiffness, should present a more severe LA dysfunction profile. We sought to evaluate the grade of LA dysfunction in elderly patients submitted to transcatheter PFO closure. Methods We retrospectively enrolled 28 consecutive patients with previous stroke （mean age 674-12.5 years, 18 females） referred to our centre for catheter-based PFO closure after recurrent stroke. Baseline values of LA passive and active emptying, LA conduit function, LA ejection fraction, and spontaneous echocontrast （SEC） in the LA and LA appendage were compared with those of 50 atrial fibrillation patients, as well as a sex/age/cardiac risk matched population of 70 healthy controls. Results Pre-closure elderly subjects demonstrated significantly greater reservoir function as well as passive and active emptying, with reduced conduit function and LA ejection fraction, when compared to healthy and younger patients. After closure in elderly patients, LAparameters did not return completely to the levels of healthy patients, whereas LA dysfunction in younger subjects returned normal. Conclusions This study suggests that elderly patients have more severe LA dysfunction than younger patients, which affects the LA remodelling after closure.

Assessment of water quality and safety based on multi-statistical analyses of nutrients, biochemical indexes and heavy metals

The purpose of this research was to better understand the water quality status of the Xiangjiang River, China, and to evaluate the risks posed by the river water. Precisely, ten water quality parameters including p H, dissolved oxygen(DO), Escherichia coli(E. coli), potassium permanganate index(CODMn), dichromate oxidizability(CODCr), five-day biochemical oxygen demand(BOD5), ammonia nitrogen(NH4+-N), total phosphorus(TP) and fluoride(F-) as well as metal(loid)s(Pb, Hg, Cd, As, Zn, Cu and Se) were monitored monthly in 2016 at 12 sampling sites throughout the Hengyang section of the Xiangjiang River. Concentrations of all parameters were presented according to rainy and dry seasons. They were compared with Chinese surface water standards and WHO drinking water limits to assess the sustainability of the river water status. Principal component analysis(PCA) revealed different pollution sources in different seasons. Dual hierarchical cluster analysis(DHCA) was applied to further classify the water quality variables and sampling sites. Besides, a risk assessment was introduced to evaluate the carcinogenic and non-carcinogenic concerns of heavy metal(loid)s to human health. This research will help to optimize water monitoring locations and establish pollution reduction strategies on the preservation of public safety.

Characterization and in-vivo evaluation of potential probiotics of the bacterial flora within the water column of a healthy shrimp larviculture system

A thorough understanding of the normal bacterial flora associated with shrimp larviculture systems contributes to probiotic screening and disease control. The bacterial community of the water column over a commercial Litopenaeus vannamei larval rearing run was characterized with both culture-dependent and culture-independent methods. A total of 27 phylotypes at the species level were isolated and identified based on 16S rDNA sequence analysis. Denaturing gradient gel electrophoresis （DGGE） analysis of the V3-V5 region of 16S rRNA genes showed a dynamic bacterial community with major changes occurred from stages zoea to mysis during the rearing run. The sequences retrieved were affiliated to four phyla, Proteobacteria, Actinobacteria, Bacteroidetes, and Firmicutes, with the family Rhodobacteraceae being the most frequently recovered one. Subsequently, 13 representative strains conferred higher larval survival than the control when evaluated in the in-vivo experiments; in particular, three candidates, assigned to Phaeobacter sp., Arthrobacter sp., and Microbacteriurn sp., significantly improved larval survival （P〈0.05）. Therefore, the healthy shrimp larviculture system harbored a diverse and favorable bacterial flora, which contribute to larval development and are of great importance in exploiting novel probiotics.

Impact of artificial waterfall using reclaimed water to VOCs and its health risk assessment

To study the impact of an artificial waterfall using reclaimed water on volatile organic compounds （VOCs） in air, air samples around the waterfall sight and over the CASS pond of a wastewater treatment plant were collected and VOCs were analyzed by MC-MS with USEPA Method TO-14. The total volatile organic compounds （TOVCs） concentration of a background sample is 2112 μg/m^3, and the sample over the CASS pond has a TVOC concentration of 1858μg/m^3. The TVOC concentrations of air samples within 10 m of the artificial waterfall are between 3216 μg/m^3 and 6362 μg/m^3, which are 1.52 - 3.0 times that of the background sample. The VOCs in air sample impacted by reclaimed water or waste water exhibit a relatively high proportion of toluene but low proportion of benzene. B/T/E/X （ Benzene/Toluene/Ethylbenzene/Xylene ） ratio of the air sample around the artificial water fall is（O. 36/11.78/1/1.10）. Health risk assessment （HRA） was done with the USEPA four-step approach. The result indicates that the artificial waterfall using reclaimed water indeed leads to the increase of human risk value. The total risk value of the sample around the waterfall is 2. 8 - 1.6 times that of the background sample. However, the total risk value of the air sample around the waterfall （2. 8 × 10^-6 ） for common people is still lower,compared to the acceptable public risk level（ 10^-5 ）. For occupational workers of the wastewater treatment plant, the sum of lifetime non-carcinogenic and carcinogenic risk values （ 1.26 × 10^ -5 ） is higher than that of the acceptable public risk level.
