Self-report Sleep Quality and its Risk Factors Among Community-dwelling Older Adults in China.

Context: Researchers have associated insomnia with many disorders, making insomnia a serious public health issue in China. Sleep quality in older adults isn't well characterized in China.

Objective: The study intended to explore the sleep quality and subjective duration of sleep in a community-dwelling older population in China and identify potential risk factors for poor sleep.

The extract from Agkistrodon halys venom protects against lipopolysaccharide (LPS)-induced myocardial injury.

Background: Snake venoms contain various bioactive constituents which possess potential therapeutic effects. The aim of this work was to investigate the effect of the extract from Agkistrodon halys venom on lipopolysaccharide (LPS)-induced myocardial injury.

Methods: Thirty male Sprague-Dawley rats were randomly assigned to three groups (10 rats per group): control group, LPS group and LPS + extract group.

[Protective effect of paeonol on neurotoxicity induced by Abeta1-42 and underlying mechanisms].

Objective: To investigate the protective effect of paeonol on amyloid beta1-42 (Abeta1-42)-induced neurotoxicity and its mechanism.

Method: Hippocampal neurons of well-grown newborn SD rats and differentiated SH-SY5Y cell lines were cultured with various concentrations of paeonol (1, 5, 10 micromol x L(-1), respectively) for 6 hours and then incubated with Abeta1-42 oligomer (30 micromol x L(-1)) for 24 hours and 48 hours, respectively. The neuron apoptosis was observed by Heochst33258.

Enhancement of mercury capture by the simultaneous addition of hydrogen bromide (HBr) and fly ashes in a slipstream facility.

Low halogen content in tested Powder River Basin (PRB) coals and low loss of ignition content (LOI) in PRB-derived fly ash were likely responsible for higher elemental mercury content (averaging about 75%) in the flue gas and also lower mercury capture efficiency by electrostatic precipitator (ESP) and wet-FGD. To develop a cost-effective approach to mercury capture in a full-scale coal-fired utility boiler burning PRB coal, experiments were conducted adding hydrogen bromide (HBr) or simultaneously adding HBr and selected fly ashes in a slipstream reactor (0.152 x 0.
