#1
Xia Wang, Qiang An, Bin Zhao, Jin Song Guo, Yuan Sheng Huang, Meng Tian
Enterobacter sp. strain FL was newly isolated from activated sludge and exhibited significant capability of auto-aggregation as well as aerobic denitrification. The removal efficiencies of NO3--N, total nitrogen (TN), and TOC by strain FL in batch culture reached 94.6, 63.9, and 72.5% in 24 h, respectively. The production of N2O and N2 in the presence of oxygen demonstrated the occurrence of aerobic denitrification. The auto-aggregation index of strain FL reached 54.3%, suggesting a high tendency that the cells would agglomerate into aggregates...

Maurice Eisenbruch
Almost one in four women in Cambodia is a victim of physical, emotional or sexual violence. This article brings together two seldom connected fields: Theory of Change (ToC) and cultural responsiveness in international development. It applies these approaches to a priority in global health, which is to prevent violence against women (VAW) and, drawing on my research on the epigenesis of VAW in Cambodia, develops an argument on the need for interventions to work with tradition and culture rather than only highlight it in problematic terms...

Sterile filters are ubiquitous in biopharmaceutical manufacturing processes. Since such filters are in direct contact with the process fluid, profiling of the extractables is of utmost importance. The work presented here reveals the extractables profile from filter cartridges for sterilizing grade filtration, which were obtained from six different vendors. All filters contain a 0.2 μm polyethersulfone (PES) membrane for sterile filtration combined with a PES pre-filter with retention rates spanning from 0...

Shizong Wang, Yanan Yin, Jianlong Wang
A novel strain capable of degrading triclosan was isolated from the acclimated activated sludge and identified to be Dyella sp. WW1 based on 16S rDNA analysis. The effect of initial concentration of triclosan (0.2, 1, 5, and 10 mg/L), temperature (15, 25, and 35 °C), pH (5, 7, and 9), and additional carbon source on the degradation of triclosan was investigated in a mineral medium. The results showed that Dyella sp. WW1 can use triclosan as sole carbon source and degrade it when initial triclosan concentration was in the range of 0...

INTRODUCTION: The broad spectrum C-8-cyano-fluoroquinolone finafloxacin displays enhanced activity at acidic conditions. This phase II clinical study compared efficacy and safety of finafloxacin and ciprofloxacin in patients with complicated urinary tract infection and/or pyelonephritis. RESULTS: A 5-day regimen with finafloxacin 800 mg q.d. (FINA05) had similar results as a 10-day regimen with finafloxacin 800 mg q.d. (FINA10). Combined microbiological and clinical responses at test of cure visit (TOC) were 70% for FINA05, 68% for FINA10, and 57% for a 10-day ciprofloxacin regimen (CIPRO10) in 193 (64 for FINA05, 68 for FINA10 and 61 for CIPRO10) patients of the microbiological intent-to-treat (mITT) population...

The present study evaluates the efficacy of S-doped MgO (S-MgO) as compared with the plain MgO as a catalyst for destructive removal of tetracycline (TTC) in aqueous solutions. The S-MgO had around 6% S in its structure. Doping MgO with S caused increase in surface oxygen vacancy defects. Adding S-MgO (12 g/L) to a TTC aqueous solution (50 mg/L) caused removal of around 99% TTC at the neutral pH (ca. 5.1) and a short reaction time of 10 min. In comparison, plain MgO could remove only around 15% of TTC under similar experimental conditions...

Mouse embryonic fibroblasts (MEFs) have extensively been used to study necroptosis, a recently identified form of programmed cell death. However, very little is yet known about the role of necroptosis and its regulation by reactive oxygen species (ROS) in cell types naturally exposed to high oxygen levels such as mouse lung fibroblasts (MLFs). Here, we discover that MLFs are highly susceptible to undergo necroptosis in a ROS-dependent manner upon exposure to a prototypic death receptor-mediated necroptotic stimulus, i...

BACKGROUND: The Scheldt estuary is historically a highly polluted river system. While several studies have focused on contamination with metals, pesticides, Polycyclic Aromatic Hydrocarbons (PAHs) and marker PolyChlorinated Biphenyls (PCBs), no data are available concerning past contamination by dioxin-like compounds. OBJECTIVES: The objective of this study is to determine spatial and time trends of PolyChlorinated Dibenzo-p-Dioxins and DibenzoFurans (PCDD/Fs) and dioxin-like PCBs (dl-PCBs) in sediment samples and Suspended Particulate Matter (SPM) from the Scheldt River basin and the North Sea Coast...

We explored the sulfur dynamics and the relationships between sediment sulfur and nutrient pools, seagrass structural and physiological variables and sulfide intrusion in native (Posidonia oceanica, Cymodocea nodosa) and exotic (Halophila stipulacea) Mediterranean seagrasses at six sites affected by cumulative anthropogenic pressures to understand the factors controlling sulfide intrusion in seagrass. Sensitive indicators of seagrass stress (leaf TN, δ15N, TS, Fsulfide) were increased at several sites, implying that seagrasses are under pressure...

We carried out geochemical analyses on a sediment core from Lake Harris, Florida (USA) to identify sources of organic matter to the sediment throughout the Holocene, and relate changes in those sources to shifts in past climate and environmental conditions. We hypothesized that the sources of organic matter changed in response to regional hydrologic shifts following de-glaciation, and to human population expansion in the state during the 20th century. Hydroclimate shifts in Florida were related to: 1) a steady rise in relative sea level and the fresh water table that began in the early Holocene, 2) wetland formation and expansion ca...

BACKGROUND: Distant metastases of papillary thyroid carcinoma (PTC) may lack the ability to concentrate radioiodine. In such cases, positive somatostatin receptor scintigraphy might be useful in demonstrating the expression of somatostatin receptors that are potential therapeutic targets. To date, only several cerebellar metastases from PTC have been reported in the literature. PATIENT FINDINGS: We present an 82-year-old female, in whom an asymptomatic cerebellar metastasis from PTC was diagnosed by the means of Tc-99m-EDDA/HYNIC-TOC scintigraphy four years following the initial diagnosis...

The oxidation of imidazolium (1-hexyl-3-methylimidazolium chloride, HmimCl) and pyridinium (1-butyl-4-methylpyridinium chloride, BmpyrCl) ionic liquids (ILs) by Fenton's reagent has been studied. Complete conversion was achieved for both ILs using the stoichiometric H2O2 dose at 70 °C, reaching final TOC conversion values around 45 and 55% for HmimCl and BmpyrCl, respectively. The decrease in hydrogen peroxide dose to substoichiometric concentrations (20-80% stoichiometric dose) caused a decrease in TOC conversion and COD removal and the appearance of hydroxylated oxidation by-products...

Reactive Electrochemical Membrane (REM) prepared from carbothermal reduction of TiO2 is used for the mineralization of biorefractory pollutants during filtration operation. The mixture of Ti4O7 and Ti5O9 Magnéli phases ensures the high reactivity of the membrane for organic compound oxidation through •OH mediated oxidation and direct electron transfer. In cross-flow filtration mode, convection-enhanced mass transport of pollutants can be achieved from the high membrane permeability (3300 LMH bar-1). Mineralization efficiency of oxalic acid, paracetamol and phenol was assessed as regards to current density, transmembrane pressure and feed concentration...

The features of extracellular dissolved organic carbon (EDOC) generation in two typical aerobic sulfur-oxidizing bacteria (Thiobacillus thioparus DSM 505 and Halothiobacillus neapolitanus DSM 15147) and its impact on CO2 fixation during chemoautotrophic cultivation process were investigated. The results showed that EDOC accumulated in both strains during CO2 fixation process. Large molecular weight (MW) EDOC derived from cell lysis and decay was dominant during the entire process in DSM 505, whereas small MW EDOC accounted for a large proportion during initial and middle stages of DSM 15147 as its cytoskeleton synthesis rate did not keep up with CO2 assimilation rate...

Nazely Diban, Ane Urtiaga
Electrochemical oxidation (ELOX) with boron-doped diamond (BDD) anodes was successfully applied to degrade a model aqueous solution of a mixture of commercial naphthenic acids (NAs). The model mixture was prepared resembling the NA and salt composition of oil sands process-affected water (OSPW) as described in the literature. The initial concentration of NAs between 70 and 120 mg/L did not influence the electrooxidation kinetics. However, increasing the applied current density from 20 to 100 A/m2 and the initial chloride concentration from 15 to 70 and 150 mg/L accelerated the rate of NA degradation...
