The liver disease related to chronic alcohol consumption is one of the leading causes of death for alcoholics. The efficient drug to ameliorate the alcoholic liver injury was needed urgently. The present study was performed to investigate whether artemisinin possessed the protective effect against chronic alcohol consumption. 50 male Kunming mice were divided into 5 groups: control group (C): 10ml/kg saline+10ml/kg saline, alcohol group (A): 10ml/kg 56%(v/v) alcohol+10ml/kg saline, low dose group of artemisinin (L): 10ml/kg 56%(v/v) alcohol+30mg/kg/day artemisinin, medium dose group of artemisinin (M): 10ml/kg 56%(v/v) alcohol+60mg/kg/day artemisinin, high dose group of artemisinin (H): 10ml/kg 56%(v/v) alcohol+120mg/kg/day artemisinin...

Anselm Wong, Andis Graudins
CONTEXT: Paracetamol (acetaminophen) poisoning is the most common cause of acute liver failure in the developed world. A paracetamol treatment nomogram has been used for over four decades to help determine whether patients will develop hepatotoxicity without acetylcysteine treatment, and thus indicates those needing treatment. Despite this, a small proportion of patients still develop hepatotoxicity. More accurate risk predictors would be useful to increase the early detection of patients with the potential to develop hepatotoxicity despite acetylcysteine treatment...

During the winter of 2013-14, 22 Canada geese ( Branta canadensis ) were admitted to the Wildlife Clinic at the Cummings School of Veterinary Medicine at Tufts University with nonspecific neurologic abnormalities and emaciation. Five of these geese, along with three geese that were submitted dead, were evaluated via histopathology, immunohistochemistry, and reverse transcription PCR (RT-PCR) for bornaviruses. Histopathologically, six of the eight birds had lymphoplasmacytic encephalitis. One bird, which also had encephalitis, had a dilated esophagus...

Anion immunity towards oxygen reduction reaction (ORR) has tremendous implications in electrocatalysis with applications for fuel cells, metal-air batteries, and oxygen depolarized cathodes (ODCs) in anodic evolution of chlorine. The necessity for exploring ORR catalysts with immunity to anion adsorption is particularly significant considering that platinum group metal (PGM) catalysts are costly and highly vulnerable to impurities such as halides. Herein, we report a metal organic framework (MOF) derived Fe-N-C catalyst that exhibits a dramatically improved half-wave potential of 240 mV compared to the state-of-the-art RhxSy/C catalyst in a rotating disk electrode in the presence of Cl-...

This work developed a facile colloidal route to synthesize BH4--capped PdxAgy nanoparticles (NPs) in water using the reducing ionic liquids of [Cnmim]BH4, and the resulting NPs were prone to form the nanocomposites with [amim]+-modified reduced graphene (RG). The removal of the metal-free inorganic ions of BH4- can create the profoundly exposed interfaces on the PdxAgy NPs during the electrooxidation, and favor the ethanol oxidation reaction (EOR) in lowering energy barrier. The counterions of [Cnmim]+ can gather ethanol, OH- ions, and the reaction intermediates on catalysts, and synergistically interact with RG to facilitate the charge transfer in nanocomposites...

The presence of Cr has already been reported in literature to cause severe degradation to La0.6Sr0.4Co0.2Fe0.8O3- δ (LSCF). However, fundamental understanding of Cr effects on the surface exchange kinetics is still lacking. For the first time in-situ gas phase isotopic oxygen exchange was utilized to quantitatively determine Cr effect on oxygen exchange kinetics of LSCF powder as a function of temperature and water vapor. Our investigations revealed that the formation of secondary phases, such as SrCrO¬4, Cr2O3, Cr-Co-Fe-O, and La-Co-Fe-O, can affect both the oxygen dissociation step and overall surface exchange...

Staphylococcus aureus (S. aureus) produces a wide variety of staphylococcal enterotoxins (SEs, SEA to SEX), which are responsible for staphylococcal food poisoning. This study is aimed to establish a system to detect SEM protein in food matrixes. In the present study, sem gene was characterized in a S. aureus isolate H4 associated with food poisoning. The amino acid sequence of the deduced SEM protein was same as that of previously identified SEM from S. aureus 04-02981. Subsequently, mature SEM protein was expressed in E...

The repeated independent evolution of similar features in divergent lineages, a process known as convergent evolution, has long been a source of fascination for both naturalists and evolutionary biologists. Until recently, this active area of research had been focused principally on the evolution of physical characteristics associated with novel traits (e.g. the independent evolution of wings in birds, bats and pterosaurs).

We present a case of a 17-year-old girl admitted to the Psychiatric Department recovering from a suicide attempt with colchicine. One week after poisoning, a sudden onset of hair loss was observed. Positive hair pull test and trichoscopy demonstrated the presence of anagen hairs with pigmented long roots covered by the root sheaths. Colchicine poisoning is an uncommon, but potentially life-threatening toxicologic emergency. An overdose of colchicine inhibits cell division, and thus the most affected organs are those which have a high rate of cell turnover...

Due to the high cost of domoic acid (DA), different carboxylic acid compounds including indole-3-acetic acid (IAA), pyrrole-2-formic acid (PFA), pyridine-2,3-dicarboxylic anhydride (PDA), trimesitinic acid (TA) and citric acid (CA) were investigated as dummy templates for the molecularly imprinted solid-phase extraction (MISPE) for selective isolation and pre-concentration of an amnesic shellfish poison (ASP), DA. The highest binding amount of the polymers towards DA was obtained when CA was used as dummy template owing to its high hydrophilicity...

STUDY HYPOTHESIS: In cases of deliberate self-poisoning (DSP), patients often ingest benzodiazepines (BZDs), known to alter memory. Experts recommend recovery of the patient's cognitive capacity before psychiatric assessment. Unfortunately, there is no validated tool in common practice to assess whether sufficient cognitive recovery has occurred after DSP with BZDs to ensure patient memory of the assessment. OBJECTIVE: The aim of the study was to identify cognitive functions and markers which predict preserved memory of the mental health care plan proposed at the emergency department after DSP...

To investigate the toxic mechanism of hexavalent chromium Cr(VI) and search for an antidote for Cr(VI)-induced cytotoxicity, a study of mitochondrial dysfunction induced by Cr(VI) and cell survival by recovering mitochondrial function was performed. In the present study, we found that the gene expression of electron transfer flavoprotein dehydrogenase (ETFDH) was strongly downregulated by Cr(VI) exposure. The levels of coenzyme 10 (CoQ10) and mitochondrial biogenesis presented by mitochondrial mass and mitochondrial DNA copy number were also significantly reduced after Cr(VI) exposure...

BACKGROUND: Carbon monoxide (CO) poisoning may cause toxicity to the cardiovascular system. However, the association between CO poisoning and the risk of major adverse cardiovascular events (MACE) remains unestablished. We investigated the incidence of MACE after CO poisoning in Taiwan and evaluated whether CO-poisoned individuals had a higher risk of MACE than did the general population. METHODS: Using Taiwan's National Health Insurance Research Database (NHIRD) during 2005-2013, a nationwide population-based cohort study was conducted among patients who experienced CO poisoning between 2005 and 2013...

BACKGROUND: In Mexico, artisans frequently use lead oxide or greta in order to produce utensils, which are destined to preparation and storage of food and drinks. Additionally, the risk of lead poisoning of artisans and their families is greater than in general population, and within these families, children are the most susceptible to lead poisoning. The aim of this study was to estimate IQ loss in Mexican children from potter families exposed to lead. METHODS: Lead concentrations in soil were determined in 19 potter's homes that functioned as pottery workshops in seven Mexican states between 2009 and 2012...

In this study, quantitative nuclear magnetic resonance (qNMR) spectroscopy of quadrupolar nuclei has been established. The complicated hydrolysis behavior of the Al(3+) ion, which causes fish poisoning and inhibits the growth of plants in environmental water, was clarified by (27)Al qNMR spectroscopy. Highly accurate simultaneous multicomponent quantitative analysis of various hydrolyzed forms of the Al ion was achieved in a non-destructive manner. The calibration curve of the external standard aqueous Al(NO3)3 solution showed excellent linearity over a very wide concentration range from 1 × 10(-4) to 1 mol L(-1) (an increase in concentration of 10 000 times), with a simple experimental and analytical procedure...

Vaccine development is one of the greatest achievements of modern medicine. Vaccines made of live-attenuated pathogens can revert to virulent live strains, which causes safety concerns. On the other hand, the use of purified antigenic components as subunit vaccines is safer, but less effective, as these components induce lower levels of protective immunity. Multiple copy presentation of an antigenic determinant in a well-ordered and well-defined orientation on a nanosized particle can mimic the natural host-pathogen surface interaction to provide antigen stability and immunogenicity similar to that of conventional vaccines with improved safety...
