Sepsis is a serious clinical disease with a high mortality rate all around the world. Liver organ dysfunction is an important sign for the severity and outcome of sepsis in patients. In this study, (1)H NMR-based metabolomics approach and biochemical assays were applied to investigate the metabolic profiling for cecal ligation and puncture (CLP) induced acute liver injury, the therapeutical effect of single/combination use of Huang-Lian-Jie-Du decoction (HLJDD) and berberine, and the interaction of them. Metabolomics analysis revealed significant perturbations in livers of septic rats, which could be ameliorated by HLJDD, berberine and their combination treatment...

This contribution is focused on the Mullins effect in polyethylene. An ultra-low-density polyethylene with 0.15 crystal content, a low-density polyethylene with 0.3 crystal content and a high-density polyethylene with 0.72 crystal content are subjected to cyclic stretching over a large strain range. Experimental observations are first reported to examine how the crystal content influences the Mullins effect in polyethylene. It is found that the cyclic stretching is characterized by a stress-softening, a hysteresis and a residual strain, whose amounts depends on the crystal content and the applied strain...

The 3rd International Consensus Conference for Breast Cancer in Young Women (BCY3) took place in November 2016, in Lugano, Switzerland organized by the European School of Oncology (ESO) and the European Society of Medical Oncologists (ESMO). Consensus recommendations for the management of breast cancer in young women were updated from BCY2 with incorporation of new evidence to inform the guidelines, and areas of research priorities were identified. This manuscript summarizes the ESO-ESMO international consensus recommendations, which are also endorsed by the European Society of Breast Specialists (EUSOMA)...

BACKGROUND: Recent data suggest that ghrelin is involved in the pathophysiology of alcohol use disorders, affecting alcohol self-administration and craving. Gastric ghrelin secretion is reduced by stomach distension. We now tested the hypothesis whether the clinically well-known effects of high-volume water intake on craving reduction in alcoholism is mediated by acute changes in ghrelin secretion. METHODS: In this randomized human laboratory study, we included 23 alcohol-dependent male inpatient subjects who underwent alcohol cue exposure...

In this study, bamboo (Phyllostachys pubescens) was successfully deconstructed using an integrated process (autohydrolysis and subsequent delignification). Xylooligosaccharides, high-purity lignin, and digestible substrates for producing glucose can be consecutively collected during the integrated process. The structural change and fate of lignin during autohydrolysis process was deeply investigated. Additionally, the structural characteristics and active functional groups of the lignin fractions obtained by these delignification processes were thoroughly investigated by NMR (2D-HSQC and (31)P NMR) and GPC techniques...

Dimethylsulphide (DMS) photo-oxidation and dimethylsulphoxide (DMSO) photoproduction were estimated in 26 laboratory irradiations of coastal samples from NE England (Tyne estuary) and W Scotland (Loch Linnhe and River Nant at Taynuilt). Pseudo-first order rate constants of DMS photo-oxidation (0.038 h(-1) to 0.345 h(-1)) and DMSO photo-production (0.017 h(-1) to 0.283 h(-1)) varied by one order of magnitude and were lowest in the coastal North Sea. Estuarine samples (salinity S < 30) had a mean DMSO yield of 96 ± 16% (n = 14), consistent with 1:1 M conversion via photosensitised oxidation by singlet oxygen...

A novel biotrickling filter using a 3D-printed honeycomb-monolith as its filter bed has been proposed and studied in this work and a solution to bed-clogging problems using pigging was demonstrated. The inlet H2S concentration in the mimic biogas was controlled around 1000 ppmv and the empty bed gas residence time (EBRT) was 41 s corresponding to a loading rate of 127 g S-H2S m(-3) h(-1). The influence of different H2S/O2 ratios on the removal performance and fate of sulfur end-products was investigated...

The occurrences of heavy metal contaminated sites and soils and the need for devising environmentally friendly solutions have become global issues of serious concern. In this study, polyaspartate (a highly biodegradable agent) was synthesized using L-Aspartic acid via a new modified thermal procedure and employed for extraction of cadmium ions (Cd) from contaminated soil. Response surface methodology approach using 3(5) full faced centered central composite design was employed for modeling, evaluating and optimizing the influence of polyaspartate concentration (36-145mM), polyaspartate/soil ratio (5-25), initial heavy metal concentration (100-500mg/kg), initial pH (3-6) and extraction time (6-24h) on Cd ions extracted into the polyaspartate solution and its residual concentration in the treated soil...

Notification of backup staff and determining their ability to augment frontline staff is a major component of any disaster plan. However, the communication and organization of this effort has many challenges. These include communication system overload, the disaster setting, disrupted transportation, and staffing impacts on normal operations. An optimal disaster notification system must have the ability to be modified to include all hazards and the unique environment in which the plan is being made. This article highlights a unique disaster staff notification system using a novel technology, an outside administrator, and a multilayer system of redundant communication...

OBJECTIVE: Numerous disasters confirm the need for critical event training in healthcare professions. However, no single discipline works in isolation and interprofessional learning is recognized as a necessary component. An interprofessional faculty group designed a learning curriculum crossing professional schools. DESIGN: Faculty members from four healthcare schools within the university (nursing, pharmacy, allied health, and medicine) developed an interdisciplinary course merging both published cross-cutting competencies for critical event response and interprofessional education competencies...

The embryos of model organism zebrafish were used to evaluate the acute toxicity of the extracts of Euphorbiae Pekinensis Radix and vinegar-processing Euphorbiae Pekinensis Radix, and the total terpene content of each extract was determined by using euphol as the reference standards. Twenty-four h normally developed zebrafish embryos were chosen, and 8 concentrations were adopted for each extract. Then the growth and death of zebrafish embryos were observed at 96 h after administration, and median lethal concentrations (LC50) of the different samples on zebrafish embryos were calculated...

Photorespiration is a central component of photosynthesis; however to better understand its role it should be viewed in the context of an integrated metabolic network rather than a series of individual reactions that operate independently. Isotopically nonstationary (13)C metabolic flux analysis (INST-MFA), which is based on transient labeling studies at metabolic steady state, offers a comprehensive platform to quantify plant central metabolism. In this chapter, we describe the application of INST-MFA to investigate metabolism in leaves...
