We analyzed trends in cardiovascular disease (CVD) mortality across BRICS associations with age, period, birth cohort.Mortality estimates were derived from Global Burden of Disease Study 2017. used age-period-cohort modeling to estimate cohort period effects CVD between 1992 2016. Period was defined as survey year, reflect population-wide exposure at a circumscribed...

The prevalence of obesity among children and adolescents has been rapidly rising in Mainland China recent decades, both urban rural areas. There is an urgent need to develop effective interventions prevent childhood obesity. Limited rigid data regarding adolescent overweight prevention are available. A national random controlled school-based intervention program was developed the mainland China. study designed as a multi-centered cluster randomized trial involving more than 70,000 aged 7–18...

We sought to develop and validate a national blood pressure (BP) reference based on age, sex, height for Chinese children. Data were obtained 197 430 children aged 7 17 who participated in the National Survey Students’ Constitution Health 2010. BP percentiles estimated fitted using lambda, mu, sigma method then compared with US China existing reference. In an external independent validation sample of 59 653 18 from provinces 2013, prevalence elevated was applying 3 references. values similar...

FTO (fat mass and obesity associated gene) was genetically identified to be with body index (BMI), presumably through functional regulation of energy homeostasis. However, the cellular molecular mechanisms by which functions remain largely unknown. Using 3T3-L1 preadipocyte as a model study role in adipogenesis, we demonstrated that is functionally required for differentiation. knock-down siRNA inhibited differentiation, whereas ectopic over-expression enhanced process. The demethylase...

An enantiospecific method for the synthesis of 4-methoxytryptophan has been developed via a regiospecific Larock heteroannulation and employed first total syntheses 9-methoxygeissoschizol 9-methoxy-Nb-methylgeissoschizol, as well opioid agonistic alkaloid mitragynine. The asymmetric Pictet-Spengler reaction Ni(COD)2-mediated cyclization served key steps.

Gene polymorphisms associated so far with body mass index (BMI) can explain only 1.18–1.45% of observed variation in BMI. Recent studies suggest that epigenetic modifications, especially DNA methylation, could contribute to part the missing heritability, and two genome-wide analysis (EWAS) have reported Hypoxia Inducible Factor 3 Alpha Subunit (HIF3A) methylation was BMI or change. We therefore assessed whether HIF3A is obesity other obesity-related phenotypes Chinese children. The subjects...
