Interfacial Electron Redistribution of Hydrangea-like NiO@Ni P Heterogeneous Microspheres with Dual-Phase Synergy for High-Performance Lithium-Oxygen Battery.

Lithium-oxygen batteries (LOBs) with ultra-high theoretical energy density (≈3500 Wh kg ) are considered as the most promising energy storage systems. However, the sluggish kinetics during the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) can induce large voltage hysteresis, inferior roundtrip efficiency and unsatisfactory cyclic stability. Herein, hydrangea-like NiO@Ni P heterogeneous microspheres are elaborately designed as high-efficiency oxygen electrodes for LOBs.

Risky Sexual Behaviors and Associated Factors Among College Students in Lusaka, Zambia.

Risky sexual behaviors are important factors driving the HIV/AIDS epidemic. Although Zambia experiences a high HIV prevalence, especially among youth, there is a dearth of information regarding risky sexual behaviors among young adults. Therefore, we investigated the prevalence and associated factors of risky sexual behaviors among college students in Lusaka, Zambia.

The impact of a health education intervention on health behaviors and mental health among Chinese college students.

This study aimed to assess the impact of a health education intervention on health behaviors, self-efficacy, and well-being among college students. Between March and October 2016, a total of 532 undergraduates participated. A theory-based intervention was conducted at Wuhan University, China.

Neutrophil elastase inhibitory effects of pentacyclic triterpenoids from Eriobotrya japonica (loquat leaves).

Ethnopharmacological Relevance: Eriobotrya japonica, a traditional herbal medicine in China and Japan, has long been used to treat chronic bronchitis and coughs.

Aim Of The Study: Pentacyclic triterpenoids (PTs), especially ursolic acid (UA), have been found as reversibly and competitively human neutrophil elastase (HNE) inhibitors. However, the limited solubility and poor bioavailability of PTs hinder their clinical use.

Associations of physical activity and fruit and vegetable intake with well-being and depressive symptoms among obese schoolchildren in Wuhan, China: a cross-sectional study.

Background: The prevalence of childhood obesity is increasing and psychological disorder is a common comorbidity of obesity. We investigated the associations of physical activity (PA) and fruit and vegetable (FV) intake with well-being and depressive symptoms among obese schoolchildren.

Methods: Participants included 188 obese children aged 9.

Cardiorespiratory Fitness Attenuates the Obesity Risk in Chinese Children Who Have Parents with Overweight/Obesity.

Objective: To evaluate the impact of parental weight status and offspring cardiorespiratory fitness on the risk of obesity among Chinese children.

Study Design: This cross-sectional study was conducted in Wuhan, China from May to June 2010. Children's height, weight, and waist circumference were measured for assessing their total and central obesity.

Cigarette smoking as a risk factor for type 2 diabetes in women compared with men: a systematic review and meta-analysis of prospective cohort studies.

Background: Few studies have investigated the effect of smoking on type 2 diabetes in women compared with men, even though several epidemiological studies provided a clear picture of the risk among the entire population.

Methods: We systematically searched PubMed and Embase up to August 2017 for prospective studies that were stratified by sex with measures of the relative risk (RR) for type 2 diabetes and current smoking compared with non-smoking. The sex-specific RRs and their ratios (RRRs), comparing women with man, were pooled using random-effects models.

Association between fruit and vegetable intake and the risk of hypertension among Chinese adults: a longitudinal study.

Purpose: Fruit and vegetable intake has been inversely associated with the risk of hypertension; however, there is inconsistent evidence on the long-term association. Given this gap in the literature, it is necessary to identify evidence from large prospective studies, especially in China, where insufficient evidence exists. Thus, we examined the association of fruit and vegetable intake with incident hypertension in Chinese adults.

17β-Estradiol on the Expression of G-Protein Coupled Estrogen Receptor (GPER/GPR30) Mitophagy, and the PI3K/Akt Signaling Pathway in ATDC5 Chondrocytes In Vitro.

BACKGROUND Osteoarthritis is a progressive inflammatory joint disease resulting in damage to articular cartilage. G-protein coupled estrogen receptor (GPER/GPR30) activates cell signaling in response to 17β-estradiol, which can be blocked by the GPR30 agonist, G15, an analog of G-1. The aims of this study were to investigate the effects of 17β-estradiol on the expression of G-protein coupled estrogen receptor (GPER/GPR30) on mitophagy and the PI3K/Akt signaling pathway in ATDC5 chondrocytes in vitro.

Combined effects of fruit and vegetables intake and physical activity on the risk of metabolic syndrome among Chinese adults.

Background: Unbalanced dietary intake and insufficient physical activity (PA) have been recognized as risk factors for metabolic syndrome (MetS). We aimed to examine the independent and combined effects of fruit and vegetables (FV) intake and PA on MetS.

Methods And Findings: A cross-sectional survey was conducted among residents of China in 2009, with fasting blood samples collected.
