The combined processes of powdered activated carbon/biological powdered activated carbon- ultrafiltration (PAC/BPAC-UF) were used to treat secondary effluent. In this study, the effect of PAC and BPAC on membrane flux, membrane resistance and the removal of different molecular weight organic compounds were investigated. In addition, the structure characteristics of the microorganisms of the BPAC were analyzed. The results showed that the optimum dosage of PAC and BPAC was 10 mg/L and 40 mg/L respectively. The reversible membrane fouling resistance of BPAC-UF was higher than that of PAC-UF, and the two processes had the least irreversible resistance at the best dosage...

Kay Neumann, Georg Griesinger
To evaluate the effect of follicular flushing on clinical outcomes (primary outcome: mean number of COCs) in poor response IVF patients a systematic literature review and meta-analysis was performed. The bibliographic databases OvidMedline (includes Pubmed), Cochrane Library and Web of Science were searched electronically for randomized controlled trials (RCTs) comparing follicular flushing with no flushing. Three RCTs with a total of 210 patients could be included. The mean number of COC did not increase with flushing (weighted mean difference: -0...

INTRODUCTION: In live donor liver transplantation (LDLT) portal flush only of the graft is done on the bench. There is no data on antegrade arterial flush along with portal flush of the graft. METHODS: Consecutive patients undergoing elective right lobe LDLT were block-randomized to receive either portal flush only or both portal and antegrade arterial flush. The primary objectives were safety, rate of early allograft dysfunction (EAD), and impact on vascular and biliary complications RESULTS: After randomization there were 40 patients in each group...

Continental Shelf Waves (CSWs) are oscillatory phenomena migrating along the continental margins, controlled by the interplay of rotation and bathymetric gradients. Here we combine observational data from five moored current meters and high-resolution hydrodynamic model fields for describing the generation and propagation of CSWs along the Southern Adriatic Margin (SAM, eastern Mediterranean Sea), where the possibility of their occurrence has been theoretically hypothesised but not experimentally observed up to now...

Nearly two decades ago, Smith (1999) recognised that little had been published on the implementation and usefulness of clinical supervision in the operating theatre. Accordingly, she conducted a small action research project and reported its findings. These were deemed to have been in a positive direction and a number of benefits were listed, essentially clustered around better communication between operating department practitioners (ODPs). Prophetically, however, she thought 'it would be interesting to observe if this enthusiasm and motivation continues after the project is completed' (p308)...

BACKGROUND: Clogged enteral feeding tubes remain a significant barrier to the delivery of nutrition, hydration, and medications to patients who cannot tolerate oral intake. There is limited research that compares the relative efficacy of different methods used to clear a clogged feeding tube. The objectives of this study were to better understand the factors that contribute to enteral feeding tube clogging and to test the efficacy of 3 methods for clearing clogged feeding tubes. METHODS: Three formulations of clogs were artificially created and tested in vitro and composed of various quantities of crushed medication (ie, aspirin) and 0...

Previous studies have indicated an association of higher alcohol intake with cardiovascular disease and related traits, but causation has not been definitively established. In this study, the causal effect of alcohol intake on hypertension in 2,011 men and women from the Ansan-Ansung cohort was estimated using an instrumental variable (IV) approach, with both a phenotypic and genotypic instrument for alcohol intake: alcohol flushing and the rs671 genotype (in the alcohol dehydrogenase 2 [ALDH2] gene), respectively...

Recent research suggests that the nation's water supply is contaminated with trace pharmaceuticals that exert a negative environmental and public health impact. Incorrect medication disposal methods (e.g. flushing medications down the toilet or drain) are a significant factor contributing to the presence of medication compounds in the aquatic environment. In this commentary, we provide a summary of the existing data on pharmaceuticals in the nation's water as well as the role of improper medication disposal methods on water contamination...

Closely related taxa occupying different environments are valuable systems for studying evolution. In this study, we examined differences in early phenology (bud set, bud burst) and early growth in a common garden trial of closely related pine species: Pinus sylvestris, P. mugo, and P. uncinata. Seeds for the trial were sourced from populations across the ranges of each species in Europe. Over first 4 years of development, clear differences were observed between species, while the most significant intraspecific differentiation was observed among plants from P...

Remediation of the sites contaminated with organic contaminants, such as chlorobenzenes, remains a challenging issue. Electroosmotic flushing can be a promising approach which is based on mechanism of electrokinetic remediation for removal of organic contaminants from fluids in low-permeability soil. To select an optimum surfactant that can effectively enhance electroosmotic flushing, three common surfactants, Triton X-100 (EK2), Tween 80 (EK3), and a mixture of sodium dodecyl sulfate and Triton X-100 (EK4) buffered with Na2 HPO4 /NaH2 PO4 solution, were tested...

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects...

Lithium gradients in plagioclase are capable of recording extremely short-lived processes associated with gas loss from magmas prior to extrusion at the surface. We present SIMS profiles of the 7Li/30Si ion ratio in plagioclase crystals from products of the paroxysmal sequence that occurred in the period 2011-2013 at Mt. Etna (Italy) in an attempt to constrain the final ascent and degassing processes leading to these powerful eruptions involving basic magma. The observed Li concentrations reflect cycles of Li addition to the melt through gas flushing, and a syn-eruptive stage of magma degassing driven by decompression that finally produce significant Li depletion from the melt...

BACKGROUND & AIMS: Primary non-function (PNF) is a rare complication after liver transplantation that requires urgent re-transplantation. PNF is associated with livers from extended-criteria donors. Clinical and biochemical factors have not been identified that reliably associate with graft function after liver transplantation. Serum patterns of N-glycans associate with changes in the liver. We analyzed perfusate from grafted liver to identify protein glycosylation patterns associated with PNF...
