Fast construction of core-shell structured magnetic covalent organic framework as sorbent for solid-phase extraction of zearalenone and its derivatives prior to their determination by UHPLC-MS/MS.

Magnetic covalent organic framework nanocomposite denoted as FeO@TAPB-Tp with core-shell structure was fabricated via a simple template-mediated precipitation polymerization method at mild conditions. The polyimine network shell was created through the polymerization of 1,3,5-tris(4-aminophenyl)-benzene (TAPB) and 1,3,5-triformyl-phloroglucinol (Tp) in tetrahydrofuran (THF) by the Schiff-base reaction. Featuring with large specific surface area (163.

Vegetable and Fruit Consumption among Chinese Adults and Associated Factors: A Nationally Representative Study of 170,847 Adults.

Objective: This study examined vegetable and fruit (VF) consumption rate and its associated factors among Chinese adults.

Methods: Nationally representative data from the 2013 China Chronic Disease Surveillance survey were used. Dietary intake data, including VF consumption during the last 12 months, were collected.

Observed and projected trends in paediatric health resources and services in China between 2003 and 2030: a time-series study.

Objectives: The two-child policy took effect in China on 1 January 2016, thus officially ending the one-child policy. The resultant growth in the population will create a considerable demand for public services such as paediatric healthcare, even while there are limited paediatric resources. We estimated the relationship between paediatric health resources and services and child mortality to determine the degree of the deficiency of such resources in China.

Molecular cloning, characterization and expression analysis of metallothionein in the liver of the teleost Acrossocheilus fasciatus exposed to cadmium chloride.

Metallothionein (MT) has a characteristic molecular structure with a cysteine-rich content. This unique structure provides metal-binding and redox capabilities and promoting metal homeostasis and detoxification in living animals. In order to evaluate the effects of cadmium (Cd) on hepatic MT expression in the liver of Acrossocheilus fasciatus, we obtained the complete cDNA of the A.

Glutathione peroxidase 1 expression, malondialdehyde levels and histological alterations in the liver of Acrossocheilus fasciatus exposed to cadmium chloride.

Cadmium (Cd) is known as a widespread pollutant in aquatic environment. The accumulation of reactive oxygen species (ROS) is attributed to Cd exposure, which may affect the growth, development and physiological metabolism of aquatic organisms. In response to these unfavorable damages, antioxidant systems have been developed to protect against oxidative stress.

Molecular cloning, expression pattern, and chemical analysis of heat shock protein 70 (HSP70) in the mudskipper Boleophthalmus pectinirostris: Evidence for its role in regulating spermatogenesis.

Heat shock protein 70 (HSP70) is molecular chaperone that is important for reproductive biological processes. In this study, a full length HSP70 from the mudskipper (Boleophthalmus pectinirostris) was characterized. It was found to contain: a 108 bp 5'-untranslated region, a 208 bp 3'-untranslated region, and a 1953 bp open reading frame, which encodes a protein of 650 amino acids with a theoretical molecular weight of 71.

Epidemics of overweight and obesity among growing childhood in China between 1997 and 2009: Impact of Family Income, Dietary Intake, and Physical Activity Dynamics.

Background: Obesity has become a major health problem among children and adolescents worldwide. This study aimed to examine the trends of overweight and obesity among childhood in China and assess their associations with family income, dietary intake, and physical activity (PA) between 1997 and 2009.

Methods: Two waves of cross-sectional data of Chinese children and adolescents aged 7-17 years from the China Health and Nutrition Survey were used.

Expression analysis of HSP70 in the testis of Octopus tankahkeei under thermal stress.

The gene encoding heat shock protein 70 (HSP70) was identified in Octopus tankahkeei by homologous cloning and rapid amplification of cDNA ends (RACE). The full-length cDNA (2471 bp) consists of a 5'-untranslated region (UTR) (89 bp), a 3'-UTR (426 bp), and an open reading frame (1956 bp) that encodes 651 amino acid residues with a predicted molecular mass of 71.8 kDa and an isoelectric point of 5.

Cloning, characterization and cadmium inducibility of metallothionein in the testes of the mudskipper Boleophthalmus pectinirostris.

Metallothioneins (MTs) are cysteine-rich, low molecular weight, and heavy metal-binding protein molecules. MT participates in metallic homeostasis and detoxification in living animals due to its abundant cysteine. In order to investigate the functions of MT during spermiogenesis in the mudskipper (Boleophthalmus pectinirostris), we identified the MT complete which contains: an 83bp 5' untranslated region, a 110bp 3' untranslated region, and a 183bp open reading frame.

Joint associations of physical activity and hypertension with the development of type 2 diabetes among urban men and women in Mainland China.

Background: Physical activity (PA) and hypertension (HTN) are important influences on the development of type 2 diabetes (T2D). However, the joint impact of PA and HTN on T2D development is unknown.

Methods: Two community-based prospective cohort studies, with the same protocols, instruments and questionnaires, were conducted among adults in urban areas of Nanjing, China, during 2004-2007 and 2007-2010.

Timing and secular trend of pubertal development in Beijing girls.

Background: Historical research is limited in changes in pubertal development in Chinese girls. We aimed to identify the timing of pubertal characteristics and the secular trend of menarche age among Beijing girls from the 1980s through the 2000s.

Methods: Six data sets were analyzed, including the Beijing Child and Adolescent Metabolic Syndrome study in 2004, where 9778 Bejing girls aged 6-18 years were studied.

Growing global burden of chronic noncommunicable diseases and an alarming situation in China.

Noncommunicable diseases (NCDs) are the leading causes of death globally, which kill more each year than all other causes combined. It is estimated that 63% of global total deaths were due to NCDs. Nearly 80% of NCD deaths occur in low- and middle-income countries.

Comparison of anthropometric indices of obesity in predicting subsequent risk of hyperglycemia among Chinese men and women in Mainland China.

Background: Obesity is a strong risk factor for hyperglycemia. However, the performance of waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), waist circumference (WC) and body mass index (BMI) in predicting hyperglycemia was inconclusive; and ethnic differences may exist in the associations.

Objective: The objective was to compare WHtR, WC, WHR and BMI in predicting hyperglycemia among Chinese adults and identify optimal cut-off points.
