Listeria monocytogenes infections: Analysis of 41 patients.

CONCLUSION: Infections caused by L. monocytogenes were uncommon but could cause severe sepsis and mortality, especially in susceptible populations. Our study focused on neurological involvement and severe invasive forms of listeriosis. Neuroinvasive forms were the most important risk factors for severe illness but not for mortality.

Authors: Yin N, Xie T, Zhang H, Chen J, Yu J, Liu F Abstract Isocitrate dehydrogenase 1 (IDH1) is the most frequently mutated gene in World Health Organization grade II-III and secondary glioma. The majority of IDH1 mutation cases involve the substitution from arginine to histidine at codon 132 (IDH1-R132H). Although the oncogenic role of IDH1-R132H has been confirmed, patients with IDH1-R132H brain tumors exhibit a better response to radiotherapy compared with those with wild-type (WT) IDH1. In the present study, the potential mechanism of radiosensitization mediated by IDH1-R132H was investigated by overexpressin...

Tuttlies, Ulrich NiekenAbstractTo better understand the interplay of fluid dynamics, mass transport, and chemical reactions in multi-phase reactors, each of these effects needs to be studied separately. In particular, reactions are hard to study separately from mass transport. In this work, using a new reactor concept a macroscopic reaction kinetics of the oxidation of toluene is determined in homogeneous liquid-phase. By operating at elevated pressure, mass transport limitations are avoided. The reactor ...

This study might be the first to explore the performance of the novel constructed microbial consortia CS-5 and BC-4 on woody biomass degradation and CPs detoxification simultaneously with CH4 production. After the degradation of CSW and CPs for 15 days by C5-5 or BC-4, significant reduction in lignocellulosic components and CPs mixture was realized with a total weight loss of 69.2 and 56.3% and CPs degradation of 89 and 95%, respectively. The toxicity of individual or mixed CPs after 15 days of degradation was reduced by approximately 90%. The synergistic action of CS-5 and BC-4 enhanced biogas and CH4 yields over 76 and 6...

In this study, the Zr-based MOFs UiO-66-NH2 was synthesized and used to adsorb Au (III) in aqueous solution. The ultrafine particle size (∼50 nm), excellent crystallinity and huge specific surface area (1039.2 m2 ·g-1) were verified by transmission electron microscope (TEM), powder X-ray diffraction (PXRD) and surface area analysis. About 50% Au (III) was adsorbed within 6 min and the maximum adsorption capacity at 298 K reached up to 650 mg·g-1, showing superiority to traditional adsorbents. The general order kinetics model and Liu equation were suitable to describe the adsorption process, which was spon...

Photothermal catalytic oxidation provides a pathway for solving these problems, but its application is always limited by lack of low-cost and active catalysts. Herein, this limitation is overcome by using doping to refine defect states. As a proof of concept, hierarchical C...
