[Electroacupuncture at "Zusanli"(ST36) ameliorates tau hyperphosphorylation in pancreas and hippocampus of diabetic rats].

Objective: To observe the effect of electroacupuncture (EA) at "Zusanli"(ST36) on the phosphorylated tau levels in pancreas and hippocampus of type 2 diabetes mellitus (T2DM) rats，so as to explore the underlying mechanism of EA in diabetic demention rats.

Methods: Forty-eight male Sprague-Dawley rats were randomly divided into control, model and EA groups, with 16 rats in each group. The T2DM model was established by 6 weeks of high-fat, high-sugar diet as well as intrape-ritoneal injection of streptozocin (STZ) solution (35 mg/kg).

[Comparison of Characteristics and Reactive Oxidative Species of PM in Xi'an, China During Haze and Clean Days].

PM samples were collected in Xi'an, China during haze(2015-11-30-2015-12-9) and clean days(2016-01-13-2016-01-22). PM mass, organic carbon(OC), elemental carbon(EC), and water-soluble ions(i.e.

[Pollution Characteristics and Sources of Carbonaceous Aerosol in PM2.5 During Winter in Guanzhong Area].

To study the characteristics and sources of carbonaceous aerosol in PM2.5 during winter in Guanzhong area, PM2.5 samples were collected from December 2012 to February 2013 in Xi'an, Baoji, Weinan and Qinling, and then organic carbon (OC) and elemental carbon (EC) were analyzed following the thermal/optical reflection protocol.

Puerarin Ameliorates D-Galactose Induced Enhanced Hippocampal Neurogenesis and Tau Hyperphosphorylation in Rat Brain.

Enhanced neurogenesis has been reported in the hippocampus of patients with Alzheimer's disease (AD), the most common neurodegenerative disorder characterized with amyloid-β (Aβ) aggregation, tau hyperphosphorylation, and progressive neuronal loss. Previously we reported that tau phosphorylation played an essential role in adult hippocampal neurogenesis, and activation of glycogen synthase kinase (GSK-3), a crucial tau kinase, could induce increased hippocampal neurogenesis. In the present study, we found that treatment of D-galactose rats with Puerarin could significantly improve behavioral performance and ameliorate the enhanced neurogenesis and microtubule-associated protein tau hyperphosphorylation in the hippocampus of D-galactose rat brains.

Effects of non-protein-type amino acids of fine particulate matter on E-cadherin and inflammatory responses in mice.

Exposure to particulate matter less than 2.5 μm (PM2.5) in size is an urgent issue for the protection of human health.

Spatial and seasonal variations of PM2.5 mass and species during 2010 in Xi'an, China.

PM2.5 mass and selected chemical species are measured in 24-h integrated PM2.5 samples collected simultaneously at the urban and rural regions of Xi'an (six sites in total), China in the four seasons of 2010.

Characterization and seasonal variations of levoglucosan in fine particulate matter in Xi'an, China.

PM2.5 (particulate matter with an aerodynamic diameter <2.5 microm) samples (n = 58) collected every sixth day in Xi'an, China, from 5 July 2008 to 27 June 2009 are analyzed for levoglucosan (1,6-anhydro-beta-D-glucopyranose) to evaluate the impacts of biomass combustion on ambient concentrations.

Methionine oxidation in albumin by fine haze particulate matter: an in vitro and in vivo study.

The potential effects of inhaled fine particulate matter (PM2.5), found in haze episodes, on the oxidation of the proteins in the lungs are not well understood. We investigated the effects of PM2.

Comparison and implications of PM₂.₅ carbon fractions in different environments.

The concentrations of PM₂.₅ carbon fractions in rural, urban, tunnel and remote environments were measured using the IMPROVE thermal optical reflectance (TOR) method. The highest OC1 and EC1 concentrations were found for tunnel samples, while the highest OC2, OC3, and OC4 concentrations were observed for urban winter samples, respectively.

Winter and summer PM2.5 chemical compositions in fourteen Chinese cities.

Unlabelled: PM2.5 in 14 of China's large cities achieves high concentrations in both winter and summer with averages > 100 microg m(-3) being common occurrences. A grand average of 15 microg m(-3) was found for all cities, with a minimum of 27 microg m(-3) measured at Qingdao during summer and a maximum of 356 microg m(-3) at Xi 'an during winter.
