This study investigated the effects of phosphorus on biofilm formation via annular reactor systems in terms of biofilm cell growth, exopolysaccharide (EPS) production, biofilm structure and cell metabolic potential.Drinking water biofilms were developed in annular reactors with supplement of carbon and different levels of phosphorus. The biofilm formation was monitored over a period of 30 days. Biofilm related parameters were examined by various methods, which included heterotrophic plate count, ...

Background and Purpose— Stroke can lead to cerebrogenic cardiac arrhythmias. We sought to investigate the effect of ischemic stroke on cardiac function in a mouse model of permanent middle cerebral artery occlusion (pMCAO). Methods— Twenty-four hours after the induction of focal ischemia, cardiac function was measured in mice by endovascular catheterization of the heart. Immediately after hemodynamic measurements, mice were euthanized and brains were excised and sectioned to measure infarct volume ...

China's collectively-owned enterprises are unconventional, as they are nominally owned by those people residing in the areas where the enterprises are located but effectively controlled by the local governments. This study finds that collectively-owned enterprises, once being privatized, encounter an increase in the cost of goods sold to sales ratio but manage to lower down the managerial expenses to sales ratio. The findings imply that local government officials may help collectively-owned enterprises ...

The rejection of steroid hormone estrone by nanofiltration (NF) and reverse osmosis (RO) membranes in treated sewage effluent was investigated. Four NF/RO membranes with different materials and interfacial characteristics were utilized. To better understand hormone removal mechanisms in treated effluent, effluent organic matters (EfOM) were fractionated using column chromatographic method with resins XAD-8, AG MP-50 and IRA-96. The results indicate that the presence of EfOM in feed solution could enhance ...

Optically pumped GaN-based vertical cavity surface-emitting laser (VCSEL) with two Ta 2 O 5 /SiO 2 dielectric distributed Bragg reflectors (DBRs) was fabricated via a simplified procedure: direct deposition of the top DBR onto the GaN surface exposed after substrate removal and no use of etching and polishing processes. Blue-violet lasing action was observed at a wavelength of 397.3 nm under optical pumping at room temperature with a threshold pumping energy density of about 71.5 mJ/cm 2 . The laser ...

Abstract Asiatic acid, a triterpenoid derivative from Centella asiatica , has shown biological effects such as antioxidant, antiinflammatory, and protection against glutamate‐ or β‐amyloid‐induced neurotoxicity. We investigated the neuroprotective effect of asiatic acid in a mouse model of permanent cerebral ischemia. Various doses of asiatic acid (30, 75, or 165 mg/kg) were administered orally at 1 hr pre‐ and 3, 10, and 20 hr postischemia, and infarct volume and behavioral deficits were evaluated ...

InGaN based light emitting devices (LEDs) with asymmetric coupled quantum wells (AS-QWs) and conventional symmetric coupled quantum wells (CS-QWs) active structures were grown by metal-organic chemical vapor deposition technique. The LEDs with AS-QWs active region show improved light emission intensity and reduced forward voltage compared with LEDs with CS-QWs active region. Based on the electroluminescence measurements and the devices structure analysis, it can be concluded that these improvements ...

We integrated the resource-, institution-, and industry-based views to investigate the determinants of export propensity and export intensity, and examined performance outcomes of firms’ export behaviors using the longitudinal data of 18,644 domestic private enterprises and foreign wholly owned subsidiaries in China from 2001 to 2005. We found that institutional environment has significant effects on export behaviors above and beyond the impact of firm competencies and industry factors. Furthermore, ...

There have been many strong retrospective observations regarding adverse effects in reproductive and fertile developments in human and the wildlife caused by the endocrine disrupting compounds (EDCs) present in the aquatic environment recently. Degradation by biomass is one of the main removal mechanisms for 17β-estradiol (E2), the most important EDC, and its conjugates from sewage in wastewater treatment plants. In this batch study, the degradation rates of E2 and its conjugates were found to be ...

China's export structure has shown a rapid shift towards more sophisticated industries. While some believe that this trend is a result of processing trade and foreign direct investment, the evidence is mixed. This paper examines variations in level of export sophistication across China's manufacturing industries. We find that an industry's level of export sophistication is positively related to the share of wholly foreign owned enterprises from OECD countries and the share of processing exports ...

This study intended to develop a robust and sensitive method for simultaneous determination of polycyclic musks (HHCB and AHTN) and nitro musks (musk xylene (MX) and musk ketone (MK)) in water samples using optimized solid-phase extraction (SPE) by gas chromatography and mass spectrometry (GC-MS). The SPE procedure was optimized in terms of selections of SPE cartridge, sample pH, elution process, etc. The method detection limits (MDLs) were from 0.09 to 0.18 ng L(-1) for the analytes. The recoveries ranged ...

Drinking water biofilm development is affected by the available nutrient levels and the presence of disinfectants. Phosphorus is recognized as another important limiting nutrient besides organic carbon. In this study, drinking water biofilms were developed in annular reactors to examine the effects of phosphorus on the biofilm disinfections with free chlorine and monochloramine. Phosphorus addition was found to increase the biofilm cell number but decrease the exopolysaccharides (EPS) production. ...

One of the major mechanisms that could produce resistance to antineoplastic drugs in cancer cells is the ATP binding cassette (ABC) transporters. The ABC transporters can significantly decrease the intracellular concentration of antineoplastic drugs by increasing their efflux, thereby lowering the cytotoxic activity of antineoplastic drugs. One of these transporters, the multiple resistant protein 7 (MRP7, ABCC10), has recently been shown to produce resistance to antineoplastic drugs by increasing ...

Abstract Purpose: Over the past few years, the alkylating agent temozolomide has become the standard-of-care therapy for patients with glioblastoma, the most common brain tumor. Recently, large-scale cancer genome sequencing efforts have identified a hypermutation phenotype and inactivating MSH6 mismatch repair gene mutations in recurrent, post-temozolomide glioblastomas, particularly those growing more rapidly during temozolomide treatment. This study aimed to clarify the timing and role of MSH6 ...

In this study, the concentrations of PFOS and PFOA in the biological units of various full-scale municipal sewage treatment plants were measured. Samples of influent, primary effluent, aeration tank effluent, final effluent and grab samples of primary, activated, secondary and anaerobically digested sludge were collected by 5 sampling events over one year. The two sewage treatment plants (STPs) selected for this study include plant A receiving 95% domestic wastewater and plant B receiving 60% industrial ...

The ring-necked pheasants (Phasianus colchicus) are widely distributed in China. We used mitochondrial DNA control-region data to investigate the origin and past demographic changes in 139 ring-necked pheasants (P. colchicus) sampled from the species' distribution range. A total of 1078 nucleotides from the control region of mitochondrial DNA were sequenced, and 88 polymorphic positions defined 102 haplotypes. High level of genetic diversity was detected in all populations studied which could be associated ...
