The obtained nanowires were characterized by x-ray diffraction, electron microscopy, x-ray photoelectron spectroscopy and electrochemical measurements. The BiPr composite oxide nanowires possess poly-crystalline structure, semi-circular tips, diameter and length of 20-100 nm and several micrometers, respectively.

Higher levels of nonylphenol were found in human urine and drinking water from rural areas as compared to metropolitan regions of Wuhan, China.

The suspected endocrine disruptor nonylphenol (NP) is closely associated with anthropogenic activities; therefore, studies on this compound have been clustered in urban areas. This study investigated the NP concentrations in drinking water sources (n = 8), terminal tap water (n = 36), and human urine samples (n = 127) collected from urban and rural areas in Wuhan, China. The mean concentrations of NP measured in drinking water sources in urban and rural areas were 92.

Methods: We conducted a cross-sectional study of 8323 women (96.4% were Han race) without polycystic ovary syndrome (PCOS) from the reproductive medical center of Tongji Hospital in Wuhan, China for assisted reproductive technology treatment between January 2016 and May 2018.

Urine Nitric Oxide Is Lower in Parents of Autistic Children.

Parents raising children with autism spectrum disorder (ASD) usually carry on their daily life under tremendous stress, but limited empirical research has been devoted to this population. It is known that parents' health status directly impacts therapeutic outcome of ASD children. As an important regulator in cardiovascular, nervous and immune systems, nitric oxide (NO) levels haven't been reported in parents of ASD children yet.

Assessment of different ventilation strategies on ventilation performance in immersed tunnels.

Investigations of ventilation in an immersed tunnel have recently drawn greater research attentions; however, analyses on the influence of vent design and tunnel width on ventilation performance have rarely been addressed. For the sake of the security of evacuees in an immersed tunnel fire, the influence of three vent designs and two immersed tunnel widths on mechanical ventilation performance during tunnel fires were numerically investigated using large eddy simulation. The pollutant gas flow characteristics in the tunnel after a fire were analyzed, and the pollutant gas exhaust efficiency based on the mass conservation of carbon monoxide in the smoke was proposed in this study.

Short-Term Exposure to Ambient Air Pollution and Mortality From Myocardial Infarction.

Background: Short-term exposure to ambient air pollution has been linked to occurrence of myocardial infarction (MI); however, only a limited number of studies investigated its association with death from MI, and the results remain inconsistent.

Objectives: This study sought to investigate the association of short-term exposure to air pollution across a wide range of concentrations with MI mortality.

Methods: A time-stratified case-crossover study was conducted to investigate 151,608 MI death cases in Hubei province (China) from 2013 to 2018.

Preparation and Phase Change Performance of Graphene Oxide and Silica Composite NaSO·10HO Phase Change Materials (PCMs) as Thermal Energy Storage Materials.

In this study, a novel nucleating agent composed of graphene oxide (GO) and silicon dioxide (SiO) (GO-SiO) is developed. GO is used as a skeleton material through which SiO nanomaterials are absorbed and subsequently incorporated into NaSO·10HO phase change materials (PCMs). Furthermore, this study examines the phase change performance of the composite NaSO·10HO materials.

Association between ambient temperature and semen quality: A longitudinal study of 10 802 men in China.

Semen quality is a vital determinant for male fertility. The process of spermatogenesis is highly sensitive to fluctuations in temperature. However, the impact of ambient temperature on semen quality remains unclear.

Oxidative damage and OGG1 expression induced by a combined effect of titanium dioxide nanoparticles and lead acetate in human hepatocytes.

Titanium dioxide (TiO(2)) is a widely used nanomaterial that can cause biological damage through oxidative stress. At low concentrations, TiO(2) can interact with lead acetate (PbAc) to produce different toxic responses, compared with TiO(2) or PbAc alone. In this study, we utilized the following as indicators of toxic responses in human embryo hepatocytes (L02): reactive oxygen species (ROS), reduced glutathione (GSH), superoxide dismutase (SOD), and the DNA adducts 8-hydroxydeoxyguanosine (8-OHdG) and 8-oxoguanine DNA glycosylase homolog 1 (OGG1).
