Vapor-Liquid-Solid Growth of Site-Controlled Monolayer MoS Films Via Pressure-Induc ed Supercritical Phase Nucleation.

In this study, a novel pressure-induced supercritical phase nucleation method is proposed to synthesize monolayer MoS films, which is promoter free and can avoid contamination of films derived from these heterogeneous promoters in most of the existing techniques. The low-crystallinity and size-controlled MoO(acac) particles are recrystallized on the substrate via the pressure-sensitive solvent capacity of supercritical CO and these particles are used as growth sites. The size of single-crystal MoS on the substrate is found to be dependent on the wetting area of the pyrolyzed precursor droplets (MoO) on the surface, and the formation of continuous films with high coverage is mainly controlled by the coalescence of MoO droplets.

Association of plasma VEGF levels and the antidepressant effects of ketamine in patients with depression.

Aims: Growing evidence suggests that vascular endothelial growth factor (VEGF) may be involved in the neuronal mechanisms underlying both depression aetiology and the response to ketamine treatments. The aim of this study was to examine whether changes in plasma VEGF levels are associated with the antidepressant effects of repeated ketamine infusions in patients with depression.

Methods: Ninety-six patients with depression were enrolled and received six ketamine infusions during a 12-day period.

[Consumptions of Meat, Dietary Fat, and Fatty-acids and Prevalence of Overweight/Obesity in Children and Adolescents-a Cross-sectional Survey in Chengdu].

Objectives: To determine the prevalence of overweight and obesity in children and adolescents aged 7-15 years in Longquanyi District of Chengdu and its association with consumptions of meat, dietary fat and fatty-acids.

Methods: A total of 1 811 children and adolescents aged 7-15 years in Longquanyi District were selected using stratified cluster sampling strategy. Their body mass, height and waist circumference were measured.

High protein intake along with paternal part-time employment is associated with higher body fat mass among girls from South China.

Purpose: Protein intake has been suggested to be associated with body composition among western children. Our aim was to determine whether protein intake is associated with body composition among Chinese children and to investigate whether parental socioeconomic status modifies these associations.

Methods: Cross-sectional data were collected from the baseline survey of an ongoing population-based prospective open cohort study conducted in 2013.

[Dietary Fiber and Pubertal Development among Children and Adolescents--a Cross-sectional Study in Chengdu, Sichuan].

Objective: To determine the association between intake of dietary fiber and pubertal development among children and adolescents in Chengdu.

Methods: A cross-sectional survey was undertaken in 1 340 children and adolescents aged 9-15 years. Data about dietary intake were collected through 24-h dietary self-recall.

[Consumptions of Meat and Dairy Products, Zinc Intake and Pubertal Development in Adolescents in Chengdu].

Objective: To determine the associations between meat, dairy and zinc intake and pubertal development in adolescents in Chengdu.

Methods: A total of 1320 children and adolescents aged 9-15 years in Chengdu were recruited using a stratified cluster sampling strategy. Dietary intake was assessed by the food frequency questionnaire (FFQ) and 3-day 24-hour dietary recall.
