Gut microbiota is currently viewed as a key regulator of a fluent bidirectional dialogue between the gut and the brain(gut-brain axis). A number of preclinical studies have suggested that the microbiota and its genome(microbiome) may play a key role in neurodevelopmental and neurodegenerative disorders. Furthermore, alterations in the gut microbiota composition in humans have also been linked to a variety of neuropsychiatric conditions, including depression, autism and Parkinson's disease. However, it is not yet clear whether these changes in the microbiome are causally related to such diseases or are secondary effects thereof. In this respect, recent studies in animals have indicated that gut microbiota transplantation can transfer a behavioral phenotype, suggesting that the gut microbiota may be a modifiable factor modulating the development or pathogenesis of neuropsychiatric conditions. Further studies are warranted to establish whether or not the findings of preclinical animal experiments can be generalized to humans. Moreover, although different communication routes between the microbiota and brain have been identified, further studies must elucidate all the underlying mechanisms involved. Such research is expected to contribute to the design of strategies to modulate the gut microbiota and its functions with a view to improving mental health, and thus provide opportunities to improve the management of psychiatric diseases. Here, we review the evidence supporting a role of the gut microbiota in neuropsychiatric disorders and the state of the art regarding the mechanisms underlying its contribution to mental illness and health. We also consider the stages of life where the gut microbiota is more susceptible to the effects of environmental stressors, and the possible microbiota-targeted intervention strategies that could improve health status and prevent psychiatric disorders in the near future.展开更多

Additionally, current research suggests that both controlled and automatic determinants account for their adoption. The purpose of this article was to identify intention-automaticity profiles toward PA and screen-based SB and to examine how those profiles are associated with different behavioral patterns. Method： Two cross-sectional studies based on self-report questionnaires were conducted with French high school students （Study 1： n = 198; Study 2： n = 185）. Results： In all, 4 distinct motivational profiles appeared. The first 3 clusters emerged in both studies： ＂PA＂ （high levels of automaticity and intention for PA, low levels of automaticity and intention for screen-based SB）; ＂screen＂ （high levels of automaticity and intention for screen-based SB, low levels of automatieity and intention for PA）, and ＂mixed＂ （high levels of all variables）, whereas the fourth cluster was observed only in Study 2： ＂high control＂ （below-mean levels of automaticity, high levels of intention toward both PA and screen-based SB）. Adolescents with a screen profile displayed the least healthy behavioral pattern, whereas those in the PA profile demonstrated the most favorable behaviors. Conclusion： Future research is needed to extend these results to other populations using complementary assessment methods of automatic psychological processes and PA and SB behaviors.2018 Published by Elsevier B.V.on behalf of Shanghai University of Sport.

The drawbacks of these models are discussed. With GPM98C as the reference, the gravity anomaly residuals of several other models, the latest SST global gravity field models (EIGEN series and GGM series), were computed and compared. The results of the comparison show that in the selected region, some systematic errors with periodical properties exist in the EIGEN and GGM’s S series models in the high degree and order. Some information that was not shown in the classic gravity models is detected in the low and middle degree and order of EIGEN and GGM’s S series models. At last, the effective maximum degrees and orders of SST models are suggested.展开更多

Contrary to the healthy parental involvement, a family can also have negative effects on an athlete development. The purpose of this study was to determine gender, father involvement, and mother involvement differences in the psychological profiles of collegiate freshmen athletes as measured by perfectionism, physical self-concept, and psychological well-being. Methods： Eighty-two male and 73 female collegiate freshmen responded to self-reported measures of family involvement, perfectionism, physical self-concept, and psychological well-being. Three separate 2 x 2 x 2 （gender x mother involvement x father involvement） factorial multivariate analysis of variance （MANOVAs） were carried out on the respective subscales from the reported measures. Results： There were significant differences for gender as well as father involvement in perfectionism （p 〈 0.01）. Freshmen females had lower concern over mistakes, and greater levels of organization as well as planfulness than males. Furthermore, freshmen athletes with high involved fathers showed greater levels of high standards for others as well as organization. Conclusion： Father involvement and mother involvement impact perfectionism, physical self-concept, and psychological well-being. perspective. extends through the freshmen year in college as shown in the athletes＇ Future research should develop better measures and utilize a family systems Copyright @ 2012, Shanghai University of Sport.

And it guarantees the implement of language communication. Thus, accumulation of a certain amount of vocabulary and the master of proper use of them is the essential condition of skillful employment of a language. The current lexical teaching in College English is far from satisfaction. Based on the findings of psycholinguistic research, this paper intends to explore an effective way to help the students enlarge their vocabulary and use them correctly with the help of various psychological associations with English vocabulary through analysis of some lexical mistakes committed in students＇ daily writing exercises.展开更多

The purpose of this study was to simultaneously assess the physiological responses and psychological experiences during salsa dance and Zumba fitness in a community sample of physically inactive women. Methods： Twenty-four participants, aged 22-56 years, visited the laboratory to perform a graded exercise test for determination of maximal oxygen uptake and maximal heart rate. The participants then attended 2 partnered salsa dance and 2 non-partnered Zumba fitness classes each in a counterbalanced order over a 2-week period. The 1-h classes were taught by certified instructors in established venues in the Royal Borough of Kingston and the surrounding communities of London, UK. Physiological data were collected using a wrist-worn ActiGraph wGT3X＋ acceler- ometer with accompanying heart rate monitor and were processed using previously validated dance-specific techniques. Psychological experiences were measured via the Subjective Exercise Experiences Scale. Results： There was a significantly higher （p 〈 0.001） total time spent in moderate-to-vigorous physical activity （51.2± 3.1 vs. 32.6 ±5.9 min）, total energy expenditure （411±66 vs. 210 ± 46 kcal）, and total step count （6773 ± 556 vs. 4108 ±781 steps） during Zumba fitness when compared to salsa dance. Significant pre- to post-class improvements in positive well-being （p 〈 0.01, partial 7/2 = 0.4l） and psychological distress （p 〈 0.001, partial 02 = 0.72） were simultaneously observed for both salsa dance and Zumba fitness. Conclusion： The acute responses to classes of partnered Latin dance and non-partnered Latin-themed aerobic dance suggest that in physically inactive women participation is indeed efficacious in terms of community-based physical activity and psychosocial health promotion.展开更多
