RESULTS AND DISCUSSION The trial quality score was 3.81, which indicates that substantial improvement is required. Government regulation, industry management and medical institution management had a positive effect on trial quality β = 0.842, 0.691 and 0.579, respectively; P less then .01. Contract research organization management had a negative effect on trial quality β = -0.476; P = .013. Research team management had no effect on trial quality β = 0.325; P = .141. WHAT IS NEW AND CONCLUSION This study is the first to model the influence of organizational management factors on the quality of phase I drug trials involving different organizations from a macro-perspective. Efforts are needed to help research teams take responsibility for trial quality and to correct the negative impact of contract research organizations on trial quality. © 2020 John Wiley & Sons Ltd.The demand for allosteric targeting of nuclear receptors is high, but examples are limited, and structural information is scarce. The retinoic acid-related orphan receptor gamma t (RORγt) is an important transcriptional regulator for the differentiation of T helper 17 cells for which the first, and some of the most promising, examples of allosteric nuclear receptor modulation have been reported and structurally proven. In a 2015 patent, filed by the pharmaceutical company Glenmark, a new class of small molecules was reported that act as potent inverse agonists for RORγt. A compound library around the central thienopyrazole scaffold captured a clear structure-activity relationship, but the binding mechanism of this new class of RORγt modulators has not been elucidated. Using a combination of biochemical and X-ray crystallography studies, here the allosteric mechanism for the inverse agonism for the most potent compound, classified in the patent as "example 13", is reported, providing a strongly desired additional example of allosteric nuclear receptor targeting. © 2020 The Authors.

Here, we highlight an indispensable role of Aurora A during the first mitotic division progression of pig embryos just after meiosis. The expression and spatiotemporal localization of Aurora A were initially assessed in pig embryos during the first mitotic division by Western blot analysis and indirect immunofluorescent staining. Then, the potential role of Aurora A was further evaluated using a highly selective Aurora A inhibitor, MLN8054, during this mitotic progression in pig embryos. Aurora A was found to express and exhibit a specific dynamic intracellular localization pattern during the first mitotic division in pig embryos. Aurora A was diffused in the cytoplasm at the prophase stage, and then exhibited a dynamic intracellular localization which was tightly associated with the chromosome and spindle dynamics throughout subsequent mitotic phases. Inhibition of Aurora A by MLN8054 treatment led to the failure of the first cleavage, with the majority of embryos being arrested in prophase of the mitotic division. Tetrahydropiperine mw Further subcellular structure examination showed that Aurora A inhibition not only led to the failure of spindle microtubule assembly, but also resulted in severe defects in chromosome condensation, accompanied by an obvious decrease in p-TACC3(S558) expression during the prophase of the first mitosis. Together, these results illustrated that Aurora A is crucial for both spindle assembly and chromosome condensation during the first mitotic division in pig embryos, and that the regulation of Aurora A may be associated with its effects on p-TACC3(S558) expression. © 2020 Blackwell Verlag GmbH.Phenyl myristate was isolated from Homalium nepalense, which is known for its therapeutic virtues in traditional medicine. However, the study of radical scavenging-capacity of phenyl myristate is limited by its relatively low abundance in medicinal plants. We have studied the isolation, structure-elucidation, and bioactivities of high-performance thin-layer chromatography validated phenyl myristate from hydroalcohol-extract of bark of H. nepalense. The chemical structure of phenyl myristate was elucidated by spectroscopic methods. The chromatography was performed on high-performance thin-layer chromatography aluminum plates coated with silica-gel 60 F254 . Determination and quantitation of phenyl myristate were performed by densitometric-scanning at 254 nm (chloroform-methanol, 91, v/v; Rf 0.49). The method was validated according to International Council for Harmonisation guidelines in terms of linearity, specificity, sensitivity, accuracy, precision, robustness, and stability. Linearity-range of phenyl myristate was 100-500 ng/5 µL with correlation-coefficient r2 = 0.9997. Limits of detection and quantitation were 3.35 and 10.17 ng, respectively. Phenyl myristate showed significant free-radical-scavenging activities in 2,2-diphenyl-1-picrylhydrazyl, oxygen-radical-absorbance-capacity, and ex vivo cell-based-antioxidant-protection-in-erythrocytes assays. Molecular-docking approach of phenyl myristate showed effective binding at active sites of human serum albumin (HSA) with the lowest binding energy (-8.4 kcal/mol) that was comparable with ascorbic acid (-5.0 kcal/mol). These studies provide mechanistic insight into the potential free radical scavenging activities of phenyl myristate. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.An elderly woman was admitted to hospital because of the presence of a necrotizing lung cavity on radiology imaging. A lung FNAC was performed, showing the presence of rare acid fast bacilli that looked like Mycobacterium tuberculosis. The necrotic material, stained by the Papanicolaou method, showed numerous crystalloid structures (figures 1A and B). They did not polarize and GMS & PAS stains were negative for fungi.
