This paper provides a literature review of current studies investigating the effects of meditation and mind-body exercise on peripheral concentrations of brain-derived neurotrophic factor(BDNF),an important mediator of the neuroplasticity of the central nervous system and cognitive function.A literature search was conducted to collect currently published randomized controlled,non-randomized controlled and uncontrolled intervention *** studies were identified;and among these studies,seven were randomized controlled studies,three were non-randomized studies,and five were uncontrolled *** limited evidence tends to support that mindfulness meditation and mind-body exercise(*** and tai chi)increase circulating BDNF concentrations in healthy and diseased *** is noteworthy that these findings are based on current studies with a relatively small sample size,or without a randomized controlled *** studies are needed to identify a definite effect of meditation or mind-body exercise on BDNF and its role in improving/maintaining brain functions in various populations.

Previous studies have shown that Physical Activity(PA)has a positive association with emotional health and intelligence in adolescents but none have focused on the relationship of PA duration and intensity on Emotional Intelligence(EI).The purpose of this study was to cross-sectionally assess the association of PA measures on overall EI and its domains in a cohort of 2029 adolescents aged 10-13 years of age in the National Longitudinal Survey for Children and youth(NLSCY)from *** linear regression analysis of EI was adjusted for age,sex,annual household income,and health ***-way analysis of variance(ANOVA)was used to relate PA duration measured in minutes,frequency,and intensity categories with continuous GEI scores and also the corresponding scores for domains of *** mean GEI scores were(28.3±6.6)for 0-30 minute(min)PA duration,(30.0±6.5)for 30 to<60 min,(30.8±6.7)for 60-120 min,and(30.1±6.5)for≥121 *** was a statistically significant linear trend across PA duration categories,p?***-hoc pairwise comparison revealed that compared to the referent category(<30 min PA category)was statistically significantly lower GEI than each of the other two PA categories(30-59 min;and 60-120 min),both p-values<*** World Health Organization(WHO)guidelines for duration and vigorous intensity were positively associated with the higher overall EI and its domains except for Stress Management.

Background:Hormone sensitive lipase(HSL) is an enzyme that regulates adipose tissue lipolysis and plays an important role in chronic exerciseinduced changes in adipose tissue *** purpose of this study was to determine whether aerobic exercise intensity influences abdominal adipose tissue HSL gene expression in obese women under weight loss. Methods:Thirty women(body mass index(BMI) = 33.0±0.7 kg/m^2,age = 58±1 years) completed one of three 20-week interventions: caloric restriction alone(CR only,n = 8),CR plus moderate-intensity exercise(CR + moderate-intensity,45%—50%heart rate reserve(HRR). 3 day/week,n = 9),or CR plus vigorous-intensity exercise(CR + vigorous-intensity,70%—75%HRR,3 day/week,n = 13).Each group had a similar prescribed energy deficit comprised of underfeeding alone(2800 kcal/week for CR only) or underfeeding(2400 kcal/week) plus exercise(400 kcal/week).Body composition and maximal aerobic capacity(VO_2max) were measured,and subcutaneous abdominal adipose tissue samples were collected before and after the *** tissue HSL gene expression was measured by real time reversetranscriptase polymerase chain reaction. Results:All three interventions reduced body weight,fat mass,percent *** waist to a similar degree(all p < 0.01).In addition,all interventions did not change absolute VO_2 max,but increased relative VO_2 max(p < 0.05 to P < 0.01).Compared to *** CR only nor CR + moderate-intensity changed adipose tissue HSL gene expression,but CR + vigorous-intensity significantly increased adipose tissue HSL gene expression(p < 0.01).The changes of HSL gene expression levels in the CR + vigorous-intensity group were significantly different from those in the CR only(p < 0.05) and CR + moderate-intensity(p < 0.01) *** the whole cohort,changes in adipose tissue HSL gene expression correlated positively to changes in absolute(r = 0.55,p < 0.01) and relative(r = 0.32,p = 0.09) VO_2 max.

观察了理气扶正中药对７周递增负荷跑台训练的雄性大鼠内分泌功能的影响。结果显示：一般训练和强化训练均未导致大鼠生殖内分泌功能的抑制；强化训练运动后大鼠血皮质酮水平升高，理气扶正中药能使强化训练运动后２４小时血睾酮、游离睾酮和ＦＳＨ水平升高。结果表明理气扶正中药促进此状态下的内分泌功能，结合以往我们运用补肾助阳中药改善运动内分泌功能紊乱的研究，以及中医关于肝肾关系的学说。

The crystal and molecular structures of K3[TbIII(nta)2(H2O)]5.5H2O (nta = nitrilotriacetic acid) and K3[YbIII(nta)2]5H2O complexes have been determined by single-crystal X- ray structural analyses. Because TbIII and YbIII have different ionic radii and electronic configura- tions, they take nine- and eight-coordinate structures with two nta ligands, respectively. The crystal of K3[TbIII(nta)2(H2O)]5.5H2O belongs to orthorhombic, space group Pccn with a = 1.6374(7), b = 1.9913(8), c = 1.5068(6) nm, V = 4.913(3) nm3, Z = 8, Mr = 769.54, Dc = 2.081 g/cm3, m = 3.476 mm-1 and F(000) = 3048. The final R and wR are 0.0432 and 0.0916 for 4961 observed reflections (I > 2.0s(I)), and 0.0814 and 0.1042 for all 21921 reflections, respectively. The [TbIII(nta)2(H2O)]3- complex anion has a nine-coordinate pseudo-monocapped square anti-prismatic structure, in which two N and six O coordinated atoms are from two nta ligands and the left ninth O atom from one water molecule. The crystal of K3[YbIII(nta)2]5H2O is of monoclinic, space group P21/c with a = 1.5579(5), b = 0.9981(3), c = 1.5956(5) nm, b = 109.776(5), V = 2.3348(13) nm3, Z = 4, Mr = 756.62, Dc = 2.153 g/cm3, m = 4.624 mm-1 and F(000) = 1484. The final R and wR are 0.0253 and 0.0657 for 4123 observed reflections (I > 2.0s(I)), and 0.0320 and 0.0731 for all 9414 reflections, respectively. The [YbIII(nta)2]3- complex anion has an eight-coordination structure with a distorted square antiprismatic prism, in which each nta acts as a tetradentate ligand with one N atom from the amino group and three O atoms from the carboxylic groups.

The electron transports in micro-architecture semiconductor are simulated using vertical SOI nMOSFET with different models. Some details in transport can be presented by changing channel length, channel thickness and drain voltage. An interesting phenomenon similar to collimation effect in mesoscopic system is observed. This may suggest the quite intriguing possibility that scattering may open new channel in sufficiently narrow devices.
