A proposed European Union (EU)-wide restriction on the use of lead gunshot for shooting in and over wetlands estimated that the societal benefits of a restriction outweighed costs, despite few identified benefits being quantified economically. A subsequent Annex XV Investigation Report on the evidence of impacts of lead ammunition in terrestrial environments concluded that additional measures to control its use are warranted, although to date this has not been further evaluated. To help inform this process, we review the literature and undertake new analyses to estimate the costs of continued use of lead ammunition associated with impacts on wildlife, people and the environment...

A hydroxynitrile lyase (HNL) from the millipede Chamberlinius hualienensis has high potential for industrial use in the synthesis of cyanohydrins. However, obtaining sufficient amounts of millipedes is difficult, and the production of the Chamberlinius hualienensis HNL (ChuaHNL) in E. coli has not been very successful. Therefore, we investigated the conditions required for high-yield heterologous production of this enzyme using Pichia pastoris. When we employed P. pastoris to express His-ChuaHNL, the yield was very low (22...

Bacillus pumilus, the thermophilic microorganism, was used to biosynthesise lipase of specific activity 5173 U. The purified lipase was highly stable in the pH range from 1 to 7 and temperature at 50 °C. The functionalized nanoporous activated carbon matrix was used for the immobilization of lipase at the optimum conditions and was used for the hydrolysis of palm oil-containing wastewater at optimum time, 3 h, pH 7, and at temperature 50 °C. The hydrolyzed palm oil wastewater was treated in an upflow anaerobic reactor for the removal of soluble COD at hydraulic retention time (HRT) of 3 days...

PURPOSE: There is lack of consensus on the prognostic value of received high dose intensity in osteosarcoma survivorship. Many studies have not shown a clear survival benefit when dose intensity is increased. The aim of this study is to go beyond chemotherapy intensification by arm-wide escalation of intended dose and/or compression of treatment schedule, while conversely addressing the relationship between treatment intensity and survival at the patient level. The study focusses on the difference in outcome results, based on a novel, progressively more individualised approach to dose intensity...

The dopamine D3 receptor (D3 R) has emerged as a promising pharmacotherapeutic target for the treatment of several diseases including schizophrenia, Parkinson's disease, and substance use disorders. However, studies investigating the D3 R's precise role in dopamine neurotransmission or how it may be exploited to modulate responses to drugs of abuse have produced contrasting results, in part because most D3 R-targeted compounds often also interact with D2 receptors (D2 R). To resolve this issue, we set out to systematically characterize and compare the consequences of selective D2 R or D3 R antagonists on the behavioral-stimulant properties of cocaine in mice, and to identify putative neurobiological mechanisms underlying their behavior-modifying effects...

An 89-year-old man presented to the emergency department with a 1-month history of upper right quadrant pain, worsened in the last 3 days and accompanied by fever and chills. On physical examination, he had scleral icterus and right upper quadrant tenderness. Laboratory findings showed hyperbilirubinemia, elevated liver enzymes and C reactive protein. The patient was admitted, suspecting of an acute cholangitis and started on antibiotics. An upper gastrointestinal endoscopy revealed the presence of a juxtapapillary diverticulum in the second portion of the duodenum, which was confirmed by a magnetic resonance cholangiopancreatography, along with upstream biliary tract ectasia...

In this work, a comprehensive investigation on the occurrence of pesticides in the Paraná 3 hydrographic basin of Paraná State, Brazil, was made by application of wide-scope screening based on ultra-high performance liquid chromatography (LC) and gas chromatography (GC) both coupled to quadrupole time-of-flight mass spectrometry (QTOF MS). The use of two complementary techniques, such as GC-QTOF MS and LC-QTOF MS, allowed screening a large number of compounds with different polarity and volatility. This screening approach was applied to 17 samples, enabling the detection of fifty-two pesticides and six metabolites...

Bismuth oxyiodide (BiOI) is a narrow band gap semiconductor which can be driven by visible irradiation. In order to efficiently separate photo-generated carriers and utilization of visible light, a facile solvothermal approach was used to synthesize a novel AgI loading BiOI 3D hierarchical composite (AgI-BiOI). The AgI-BiOI with Ag and Bi molar ratio of 1:8 (AgI-BiOI (1-8)) showed great enhancement for photocatalytic degradation of bisphenol A (BPA) with pseudo-first degradation rate constant about 3.7 or 14...

We assessed spatial distribution of infiltration capacity under forest canopies to simulate runoff processes in a steep small catchment in Japan. High resolution LiDAR data were used to assess light availability to understory vegetation, which in turn was converted into an understory vegetation cover ratio. Spatially distributed infiltration capacities based on data from field rainfall-runoff experiments were incorporated into the TopoTube model using a relationship between infiltration capacity and vegetation cover...

With widely reported antibacterial potential, the copper-containing nanoparticles have become attractive antibacterial agents to prohibit the undesirable bacterial adhesion and growth. However, after applying the copper-containing agents in the environment, the potential leaching and bioaccumulation of copper ions may cause severe environmental contamination and irreversible health problems. Therefore, the nano CuAl2 O4 spinel was fabricated as a novel copper-stabilized antibacterial agent with much minimized copper leachability...

This work reports the development and application of a multi-compound analysis method for the determination of 17 flavonoids and polyphenols in sweet potato leaves. Samples were processed by microwave-enhanced accelerated solvent extraction under low pressure at 120 °C for 10 min. Salting-out homogeneous liquid-liquid extraction was used to remove water and water-soluble impurities from the extract before ultra performance convergence chromatography-tandem mass spectrometry analysis. By using the supercritical fluid (CO2 and methanol) as the mobile phase, the 17 components and the internal standard were well separated in 10 min without obvious matrix effect...

BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory condition of the intestines and is difficult to cure once diagnosed. The efficacy of the current clinical treatment for UC is limited. Common anti-inflammatory drugs are prone to adverse effects, while novel biological agents are expensive, although tolerated by patients. Therefore, an urgency exists to find more safe and effective drugs to treat UC. Osthole is an active constituent isolated from the fruit of Cnidium monnieri (L...
