In this study,we focused on NPY m RNA expression changes around feeding time and during food deprivation in olive flounder. The olive flounder NPY m RNA levels were analyzed in different tissues and a high level of expression was detected in the brain. We also demonstrated a correlation between NPY expression levels in the brain and feeding schedule. NPY expression levels in olive flounder maintained on a daily scheduled feeding regimen increased shortly before feeding and decreased after the scheduled feeding time. Compared with the-1 h group before feeding,NPY expression in the 3 h group after feeding decreased significantly( P <0.05). Food deprivation led to an 81.7% decrease in NPY m RNA levels in the 24 h fasted group(P <0.05) and a 91.7% decrease in the 48 h fasted group(P <0.05). Therefore,our study demonstrates that NPY expression is associated with food intake in olive flounder. This result reveals the function of NPY in regulating food intake and its potential importance in olive flounder aquaculture.展开更多

Data for this analysis were from the 2010 Mongolia Global School-Based Health Survey （GSHS）. The GSHS administered a self-report questionnaire to a nationally representative sample （N = 5,328） of 7th-llth grade school children. Chi-square analyses and multivariate logistic regressions were performed to determine the prevalence and to predict the fruit and vegetable intake from associated factors. Only 7.0% of students met WHO＇s recommendation of eating fruits and vegetables S or more times per day. There was a significant association between gender and fruit and vegetable intake （P = .016）. There was a significant relationship between living condition and fruit and vegetable intake （P =.029）. Students who lived in apartment were more likely to have adequate fruit and vegetable intake than those who lived in ger in the khashaa. To be effective, educational interventions should be implemented as early as possible.展开更多
