09 min in groups I and II, respectively (P less then  0.05).The mean hemoglobin levels on admission and 24 h after placental deliveries were significantly higher in group I than group II. CONCLUSIONS Intra-umbilical injection of 400 and 800 μg misoprostol were both safe and effective methods for delivery of retained placenta. © 2020 Japan Society of Obstetrics and Gynecology.Microfluidic single-cell cultivation (MSCC) is an emerging field within fundamental as well as applied biology. During the last years, most MSCCs were performed at constant environmental conditions. Recently, MSCC at oscillating and dynamic environmental conditions has started to gain significant interest in the research community for the investigation of cellular behavior. Herein, an overview of this topic is given and microfluidic concepts that enable oscillating and dynamic control of environmental conditions with a focus on medium conditions are discussed, and their application in single-cell research for the cultivation of both mammalian and microbial cell systems is demonstrated. Furthermore, perspectives for performing MSCC at complex dynamic environmental profiles of single parameters and multiparameters (e.g., pH and O2 ) in amplitude and time are discussed. The technical progress in this field provides completely new experimental approaches and lays the foundation for systematic analysis of cellular metabolism at fluctuating environments. © 2020 The Authors.

Crystal structures are indispensable for the efficient structure-based design of P450BM3 as a biocatalyst. The abietane diterpenoid derivative N-abietoyl-l-tryptophan (AbiATrp) is an outstanding crystallisation accelerator for the wild-type P450BM3 haem domain, with visible crystals forming within 2 hours and diffracting to a near-atomic resolution of 1.22 Å. Using these crystals as seeds in a cross-microseeding approach, an assortment of P450BM3 haem domain crystal structures, containing previously uncrystallisable decoy molecules and diverse artificial metalloporphyrins binding various ligand molecules, as well as heavily tagged haem-domain variants, could be determined. Some of the structures reported herein could be used as models of different stages of the P450BM3 catalytic cycle. © 2020 Wiley-VCH Verlag GmbH & Co.

The tumorigenesis of CVS and SVS have not been fully elucidated, and this study was designed to identify differentially expressed proteins involved in the tumorigenesis of CVS and SVS. EXPERIMENTAL DESIGN Tandem mass tag-based proteomics was used to determine the protein expression profiles from CVS and SVS tissues. RESULTS A total of 30 differentially expressed proteins were identified between CVS and SVS, with 6 being upregulated and 24 being downregulated. Bioinformatics analyses were performed according to Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. These results indicated that two selected proteins (COL1A1 and COL1A2) were potential biomarkers for distinguishing CVS and SVS. CONCLUSIONS AND CLINICAL RELEVANCE We identified differentially expressed proteins linked to CVS and SVS, and these proteins might provide potential biomarkers for human VS diagnosis. Furthermore, the present study supports the notion that decreased collagen might be the reason for bleeding associated with CVS. This article is protected by copyright.

The spectrum of findings has differed from the classical silicosis previously described, with many features of accelerated disease, including ground-glass opacities and progressive massive fibrosis. This cohort of patients presents after exposure to a unique product high in silica and other binding agents, and the patterns of disease on imaging in this cohort are not previously described. This article reviews the radiological features seen in different forms of silicosis seen to date in this Australian cohort. © 2020 The Royal Australian and New Zealand College of Radiologists.B-cell non-Hodgkin's lymphoma (NHL) is a class of heterogeneous diseases with variable clinical outcomes. Immunosuppression is particularly common in the subtypes of lymphoma with poor prognosis, but the underlying mechanism remains unclear. Using a RT-PCR array analysis, we have identified that glycosyltransferase 1 domain-containing 1 (GLT1D1), an enzyme that transfers glycosyl groups to proteins, is highly up-regulated in the incurable subtype of B-cell NHL and in early relapse diffuse large B-cell lymphoma. Analysis of clinical specimens revealed that GLT1D1 expression was positively correlated with the level of glycosylated programmed cell death-ligand 1 (PD-L1) in B-cell NHL and that high GLT1D1 expression was associated with poor prognosis. Mechanistically, we showed that GLT1D1 transferred N-linked glycans to PD-L1, thus promoting the immunosuppressive function of glycosylated PD-L1. Down-regulation of GLT1D1 resulted in a decrease of glycosylated PD-L1 and enhanced cytotoxic T cell function against lymphoma cells. In vivo, overexpression of GLT1D1 promoted tumor growth by facilitating tumor immune escape through increased levels of PD-L1. Our work has identified GLT1D1 as a predictive biomarker for B-cell NHL. It has also shown that this enzyme enhances PD-L1 stabilization via N-glycosylation, thus promoting immunosuppression and tumor growth. As such, GLT1D1 might be a novel therapeutic target for treatment of B-NHL. This article is protected by copyright.

In the current paper we open up the potential of SuFEx reactions as enantioselective reactions, analyze the role of Si and outline the mechanism of this reaction. As a result, fast, high-yielding, "Si-free" and enantiospecific SuFEx reactions of sulfonimidoyl fluorides have been developed, and their mechanism shown, by both experimental and theoretical methods, to yield chiral products. © 2020 Wiley-VCH Verlag GmbH & Co.
