Selective synthesis of nitrate from air using a plasma-driven gas-liquid relay reaction system

The direct oxidation of nitrogen is a potential pathway to achieving the zero-carbon-emission synthesis of nitric acid or nitrate, because it does not involve ammonia synthesis and additional ammonia oxidation processes. However, the slow kinetics of nitrogen oxidation and the difficult selective control of oxidation products hinder the development of this process. In this study, a plasma-driven gas-liquid relay reaction system was developed to overcome these limitations. A typical feature of this reaction system is that it can efficiently generate NO_x under plasma exposure;moreover, the specific anions in the absorption solution can be oxidized to strong oxidants capable of relay oxidation of low-valence nitrogen oxides. This feature allows for the deep oxidation of nitrogen, thus enabling the oxidation products of nitrogen to exist in high-valence states in the absorption solution. For experimental verification, we achieved the 100% selective synthesis of nitrate under plasma exposure, with air as the supply gas and a sodium sulfate solution as the absorption solution.

Effects of Exercise on Behavior and Peripheral Blood Lymphocyte Apoptosis in a Rat Model of Chronic Fatigue Syndrome

This study examined the effects of exercise on behavior and peripheral blood leukocyte apoptosis in a rat model of chronic fatigue syndrome （CFS）. Thirty-six healthy male Sprague-Dawley rats were equally randomized into 3 groups： the control group, CFS model group and the exercise group in terms of body weight. A total of 25 rats entered the final statistical analysis due to 11 deaths during the study. CFS model was established by subjecting the rats in CFS model group and exercise group to electric shock, chronic restraint stress and cold water swim. Besides, rats in the exercise group took rtmning wheel exercise. After a week of conditioning feeding, model construction and running wheel exercise were performed simultaneously, and lasted for 23 consecutive days. The behavior experiments, including running wheel exercise, open-field test, tail suspension test and Morris water maze test, were conducted, either before or after the model establishment. Rats were sacrificed and peripheral blood was obtained for the assessment of lymphocyte apoptosis index by flow cytometry （FCM）. It was found that as compared with those in the control group, the weight of the rats was decreased obviously （P〈0.01）, the mobility time in the open-field and the tail suspension tests was shortened significantly （P〈0.01）, the time to locate the platform was enhanced （P〈0.01） and the cell apoptosis index was increased substantially （P〈0.01） in the CSF model group. Meanwhile, in comparison to the model group, the behavior in the open-field and the tail suspension tests was improved significantly （P〈0.05）, and the apoptosis index decreased remarkably （P〈0.01） in the exercise group. It is concluded that sport intervention can prevent lymphocyte apoptosis and improve animal behavior rather than the memory.

Muscle-Strengthening Exercise Links with Lower Odds for Depression in Adolescents

Purpose:Physical activity is a well-recognized protective factor against depression in adolescents.As a compo-nent of physical activity,muscle strengthening exercise(MSE)is also viewed as a correlate associated with lower risks of depression in adults.However,little is known about the association in adolescents.This study aimed to explore the association between MSE and depression in a sample of Chinese adolescents.Method:A self-reported questionnaire was used for data collection including variables of MSE,depression(assessed by Children’s Depres-sion Inventory)and selected sociodemographic factors(e.g.,sex,grade,height and weight[for body mass index]).Generalized Linear Models was utilized to estimate the association between MSE and depression.Results:Results showed a negative association between MSE and depression(Beta=–0.66;both MSE and depression were treated as continuous variables).When treating MSE(meeting or not meeting the recommendations)and depression as binary variables,odds ratio for depression in adolescents not meeting the MSE recommendation was significant higher(odd ratio=1.50,95%CI:1.15–1.96)than those meeting the MSE recommendations.Conclusions:This study found that MSE may be a protective factor against MSE in adolescents.Future studies are encouraged to confirm or negate our studyfinding using improved study design.

The Acute Effects of Aerobic Dance Exercise with and without Face Mask Use on Attention, Perceived Exertion and Mood States

The present study aimed to determine the effect of wearing a face mask during aerobic dance exercise on cognitive function,more specifically on attention,as well as on perceived exertion and mood states.Thirteen healthy college students(9 males and 4 females:mean age=17.5 years,height=1.72 m,weight=71.00 kg)volunteered to participate in this study.They were randomized to perform aerobic dance exercise while wearing a cloth face mask or no mask or a control condition(sitting on a comfortable chair and reading information about the health benefits of aerobic dance exercise)on three separate occasions(with at least one week of interval).Rate of perceived exertion(RPE),the Brunel Mood Scale(BRUMS)and d2 Attention assessment were assessed before and immediately after each condition.The results demonstrated higher concentration performance for the aerobic dance exercise without face mask than the control condition(p=0.05).Post RPE and BRUMS fatigue subscale values were significantly higher in the aerobic dance exercise with face mask as compared to the aerobic dance exercise without face mask and control condition(all,p<0.05).BRUMS vigor subscale value significantly differed across conditions(F=113.84,p<0.001,ES=0.86)and was significantly higher in the aerobic dance exercise group without face mask as compared to the aerobic dance exercise with face mask and the control conditions(both,p<0.001).This study suggests that face mask use during aerobic dance exercise with moderate intensity did not affect attention.Practitioners,students and athletes should avoid wearing face mask while practicing physical activity or aerobic dance exercise with moderate intensity to improve its acute effect on cognitive function.

One-hour after-school exercise ameliorates central adiposity and lipids in overweight Chinese adolescents： a randomized controlled trial

Background The prevalence of overweight and obesity in Chinese children and adolescents was increasing during the past few decades. The goal of this study was to investigate the effects of after-school exercise with or without diet restriction on total and central obesity, fitness level, and metabolic profile in overweight Chinese adolescents.Methods A ten-week weight loss trial was performed using a 2×2 block design （exercisexdiet）. Ninety-three overweight adolescents （average age：（13.6±0.7） years; body mass index （BMI）： 22.4-34.1 kg/m2） were randomly assigned to four groups：1） diet （D）; 2） exercise （EX）; 3） diet plus exercise （DEX）; and 4） overweight control （C）. Caloric intake recipes were enacted based on individual age and corresponding ideal body weight. One-hour after-school exercise was performed once per day, four days per week for ten weeks. Changes of anthropometry, body composition, aerobic fitness,and metabolic biomarkers were determined.Results Groups D, EX and DEX had a significant decrease in BMI （P〈0.01） after the intervention. The percentage of body and truncal fat, and waist circumference were independently reduced by exercise （P〈0.05 and P 〈0.01）, but not diet. The decrease in body fat percentage was positively related with the exercise compliance （r=0.34,P=0.01）. Exercise decreased truncal fat percentage and waist circumference, suggesting a reduction of central adiposity, but did not significantly affect body weight and BMI. Exercise significantly reduced serum low-density lipoprotein cholesterol （P=0.037）, which was positively correlated with decreases of truncal fat percentage （r=0.222, P=0.048）. No significant effects of interventions on insulin sensitivity, early insulin release index, and aerobic fitness were observed.Conclusion At least twice a week of one-hour after-school exercise significantly attenuated central adiposity and had a significant impact on lipid profiles in overweight Chinese adolescents.

Anthropometric Characteristics of Elite Male Taekwondo Players Based on Weight Categories

Purpose The aim of this study was to investigate the anthropometric characteristics of elite taekwondo players based on weight categories,and to determine if the length of the lower extremities might influence player’s success-level.A total of 59 elite male taekwondo players(22.02±3.07 years)participated in this study.Methods All anthropometric assessments were performed according to the standards and methodology of the International Society for Advancement of Kinanthropometry.The 18 anthropometrical variables were measured for each athlete and compared between 7 different weight categories.The players were also divided into two groups(national and international)and the ratios of sitting-height to stature were compared.Results There were significant differences(P<0.05)between weight divisions in stature,body mass index,percentage of body fat,endomorphy,and mesomorphy,which were greater(P<0.05)in heavy weight groups than light weight groups,and ectomorphy,which was greater(P<0.05)in very light weight groups compared with the other weights.There was no significant difference in lean mass index(P>0.05)between weight groups.Sitting height/stature ratio was significantly dif-ferent(P<0.05)between the two groups,where the international group had longer lower extremities than the national group.Conclusion The findings of this study provide a valuable framework to support talent identification programmes and the development of specialised preparatory strategies for different weight divisions with the sport.

Weighted ■_(p)-Minimization for Sparse Signal Recovery under Arbitrary Support Prior

Weighted ■_(p)(0<p<l)minimization has been extensively studied as an effective way to reconstruct a sparse signal from compressively sampled measurements when some prior support information of the signal is available.In this paper,we consider the recovery guarantees of Κ-sparse signals via the weighted ■_(p)(0<P<1)minimization when arbitrarily many support priors are given.Our analysis enables an extension to existing works that assume only a single support prior is used.

Effects of Aerobic Exercise on Atherosclerotic Risk in Postmenopausal Women

Introduction To study the effects of aerobic exercise on lipid metabolism,endothelial function,and oxidative stress reaction in postmenopausal women,in order to prevent and control atherosclerosis.Methods Thirty-two women with natural menopause were randomly divided into an exercise group and a control group.Participants in the exercise group(n=16)took part in a 3-month aerobic training program according to their exercise pre-scription,while participants in the control group(n=16)maintained their usual lifestyles.Lipids,endothelial function,and oxidative stress-related indicators were measured before and after the intervention.Results After 3 months of aerobic training at an intensity of 50-60%of cardiorespiratory fitness,serum total cholesterol and low-density lipoprotein cholesterol decreased significantly(P<0.05),and high-density lipoprotein cholesterol increased significantly(P<0.01).A significant reduction in endothelin(P<0.01)and a significant increase in nitric oxide(P<0.05)were also observed.The training intervention also delayed the increase in homocysteine and cysteine aspartate-specific protease-3 in postmenopausal women.Conclusions Aerobic exercise had a positive effect on blood lipids,endothelial function,and oxidative stress of postmeno-pausal women,and these changes may mitigate the risk of atherosclerosis occurrence.Similar exercise programs could be used as a primary atherosclerosis prevention strategy for postmenopausal women.
