Still, ESCC-targeted therapy has not been covered yet. In the present study we have identified that Licochalcone B (Lico B) inhibited the ESCC growth by directly blocking the Janus kinase (JAK) 2 activity and its downstream signaling pathway. Lico B suppressed KYSE450 and KYSE510 ESCC cell growth, arrested cell cycle at G2/M phase and induced apoptosis. Direct target of Lico B was identified by kinase assay and verified with in vitro and ex vivo binding. Computational docking model predicted for Lico B interaction to ATP-binding pocket of JAK2. Furthermore, treatment of JAK2 clinical medicine AZD1480 to ESCC cells showed similar tendency with Lico B. Thus, JAK2 downstream signaling proteins phosphorylation of STAT3 at Y705 and S727 as well as STAT3 target protein Mcl-1 expression was decreased with treatment of Lico B. Our results suggest that Lico B inhibits ESCC cell growth, arrests cell cycle and induces apoptosis, revealing the underlying mechanism involved in JAK2/STAT3 signaling pathways after Lico B treatment. It might provide potential role of Lico B in the treatment of ESCC. © 2020 John Wiley & Sons, Ltd.As genetic counseling services expand and reach a wider catchment of the population, there is a critical need to better understand the impact of services on a greater diversity of patients. We conducted a systematic review to evaluate genetic counseling experiences and outcomes among racial and ethnic minorities. Six databases extracted articles published from 2005 to 2019 that assessed genetic counseling participation, knowledge and awareness, motivators, barriers, perceptions, and outcomes for racial and ethnic minority populations in the United States. Genetic counseling outcomes were categorized using the Framework for Outcomes of Clinical commUnication Services. A total of 1,227 abstracts were identified, of which 23 papers met inclusion criteria. Results suggest the possibility of racial and ethnic differences in some genetic counseling experiences and outcomes but noted differences were not adequately replicated between studies. The few included studies differed greatly in aims, methods, and results, which made comparison across study designs challenging and effectively barred thematic analysis. Additional research is needed that includes more study populations and settings with patients of diverse racial and ethnic backgrounds, as well as more structured study designs that allow for elucidations of differences between White and non-White populations. © 2020 National Society of Genetic Counselors.Puffers show good drag reduction performance during migration. It is worth noting that spines which are different from ordinary fish scales are densely distributed on the puffer skin. Here, the special morphological structure of puffer spines was observed using microscopy techniques, accurate contour models were established based on image processing techniques and curve fitting, then feature sizes were obtained. Based on the results, the nonsmooth surface was established by orthogonal test to simulate the flow field. In addition, the influence of spinal structure on boundary layer flow field and the drag reduction property of nonsmooth surface were further analyzed. The nonsmooth surface formed by spinal structure elements can effectively reduce the wall shear stress and Reynolds stress, and there was a special "climbing vortex" phenomenon, so as to reduce the surface viscous friction resistance and achieve drag reduction. Compared with the smooth surface, the drag reduction rate of the nonsmooth surface was 12.94% when the inflow velocity was 5 m/s, which revealed and verified the drag reduction performance of the spines of puffer skin. The results lay a foundation for further research and optimization of drag reduction ability of nonsmooth surface of bionic spines. © 2020 Wiley Periodicals, Inc.BACKGROUND Patient head motion is a major concern in clinical brain MRI, as it reduces the diagnostic image quality and may increase examination time and cost. PURPOSE To investigate the prevalence of MR images with significant motion artifacts on a given clinical scanner and to estimate the potential financial cost savings of applying motion correction to clinical brain MRI examinations. STUDY TYPE Retrospective. SUBJECTS In all, 173 patients undergoing a PET/MRI dementia protocol and 55 pediatric patients undergoing a PET/MRI brain tumor protocol. The total scan time of the two protocols were 17 and 40 minutes, respectively. FIELD STRENGTH/SEQUENCES 3 T, Siemens mMR Biograph, MPRAGE, DWI, T1 and T2 -weighted FLAIR, T2 -weighted 2D-FLASH, T2 -weighted TSE. ASSESSMENT A retrospective review of image sequences from a given clinical MRI scanner was conducted to investigate the prevalence of motion-corrupted images. The review was performed by three radiologists with different levels of experience using a three-NICAL EFFICACY Stage 6. © 2020 International Society for Magnetic Resonance in Medicine.Fluorescence microscopy has emerged as an attractive technique to probe the intracellular processing of Pt-based anticancer compounds. Herein, we reported the first Through-Bond Energy Transfer (TBET) fluorescent probe NPR1 designed for sensitive detection and quantitation of Pt II complexes. The novel TBET probe was successfully applied for ratiometric fluorescence imaging of anticancer Pt II complexes such as cisplatin and JM118 in cells. Capitalizing on the ability of the probe to discriminate between Pt II complexes and their Pt IV derivatives, the probe was further applied to study the activation of Pt IV prodrug complexes that are known to release active Pt II species after intracellular reduction. © 2020 WILEY-VCH Verlag GmbH & Co.

The antioxidant activity of these derivatives was explored by different experimental assays, such as ABTS ●+ and DPPH ● scavenging assay, as well as Reducing Power assay. The structural differences are discussed in terms of the results. Salinomycin in vivo Then, sulfur analogs showed higher antioxidant activity than the oxygenated counterparts. The same tendency was observed in the microbiological studies, where the same imidazoline compounds were assayed for light-mediated activity against strains of Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ). A light-enhanced activity was observed for almost all the sulfurated imidazolines after exposure to  to UV-A (400-320 nm) light. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
