MoS2 with tunable surface structure directed by thiophene adsorption toward HDS and HER

MoS2 catalysts with more active sites and larger surface areas were successfully synthesized via a simple hydrothermal reaction method, and the surface structure of MoS2 was readily tailored by simply adding thiophene during the synthesis procedure. The MoS2 samples synthesized with thiophene, especially MoS2 prepared with 200 μL of thiophene, concomitantly exhibited better...

Prenatal and early life home environment exposure in relation to preschool children’s asthma, allergic rhinitis and eczema in Taiyuan, China

Prenatal and early life home environment might be related to children’s asthma or allergic diseases later in life. A cross-sectional epidemiological study was designed and a questionnaire survey was performed in 3700 preschool children in urban areas in Taiyuan, Shanxi Province, China. Questions on children’s asthma and allergic diseases from the International Study on Asthma and...

Deficient FGF signaling causes optic nerve dysgenesis and ocular coloboma

Frs2α and Shp2 signal independently of Gab to mediate FGF signaling in lens development

Fibroblast growth factor (FGF) signaling requires a plethora of adaptor proteins to elicit downstream responses, but the functional significances of these docking proteins remain controversial. In this study, we used lens development as a model to investigate Frs2α and its structurally related scaffolding proteins, Gab1 and Gab2, in FGF signaling. We show that genetic ablation of...

Antigenic epitope peptides of influenza H3N2 virus neuraminidase gene based on experiments

The neuraminidase (NA) in viral surface is one of the main subtype-specific antigen of influenza type A viruses. Neuraminidase is an enzyme to break the bonds between hemagglutinin (HA) and sialic acid to release newly formed viruses from infected cells. In this study, the H3N2 subtype virus NA genes were sequenced and NA proteins were screened for B-cell epitopes and assessed...

Influence of deposition time on the morphology and optical properties of SiO2-ZnO composite photonic crystals

SiO2 photonic crystal were successfully prepared by vertical deposition and then used as a template to fabricate SiO2-ZnO composite photonic crystals on ITO substrates by electrodeposition and subsequent calcination. A number of different deposition times were used. The morphologies of the silica opals and SiO2-ZnO composite photonic crystals were investigated by scanning...

Serum levels of perfluorinated compounds in the general population in Shenzhen, China

Perfluorinated compounds (PFCs) have been detected in many environmental matrices, biota, and nonoccupationally exposed populations in China recently. However, little is known about the distribution and levels of various PFCs in the general population living in areas where there is PFC exposure. In the present study, the levels and prevalence of ten target PFCs were determined in...

Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China

Asthma, rhinitis and eczema (allergic or non-allergic) have increased throughout the world during the last decades, especially among children. Changes in the indoor environment are suspected to be important causes. China has experienced a dramatic change in indoor environmental exposures during the past two decades. However, such changes and their associations with children’s...
