Considering the fundamental role played by CSCs in carcinogenesis, reported data strengthen the hypothesis that sustains a pivotal role of NNMT in cancer growth and metastasis. In addition, these findings could represent an important achievement for the development of new and effective anticancer therapies, based on CSC-associated targets. © 2020 International Union of Biochemistry and Molecular Biology.Cytometer characterization is critical to define operational bounds within which the data generated are reliable and reproducible. Existing instrument optimization and characterization protocols were developed for cytometers relying on photomultiplier tubes (PMTs) for photon detection. Recently, instrument manufacturers have begun incorporating avalanche photodiodes (APDs) in place of PMTs. Differences in noise and signal amplification properties of the two detector types make many of the established PMT characterization protocols inappropriate for APD-based instruments. In this article, we tested (three machines on two different sites) a variety of approaches to determine the best method for APD optimization on the Beckman Coulter CytoFLEX™ (CytoFLEX). From this, we propose easy-to-implement guidelines for CytoFLEX characterization and operation. These protocols are not designed to compare APD versus PMT based systems, nor are they designed to directly compare different CytoFlex instruments. Following these protocols will allow CytoFLEX users to characterize their instruments and help to identify optimized settings that allow for the generation of consistent and reproducible data. © 2020 International Society for Advancement of Cytometry.The use of the Watchman left atrial appendage occlusion device (Boston Scientific Inc.) is becoming increasingly frequent in patients with atrial fibrillation. Cardiac computed tomography (CT) for device sizing pre-procedure can help facilitate more accurate device selection compared with transesophageal echo (TEE) alone. CT can also help identify minor lobes and trabeculations that may not be apparent on TEE. We report a series of three cases to highlight the utility of a novel application of CT-TEE fusion imaging to provide procedural guidance during Watchman implant and to assess for peri-device leak post-implant. © 2020 Wiley Periodicals, Inc.For all-polymer solar cells, the effect of alkyl side chains on photovoltaic performance is a matter of some debate, and this effect remains difficult to forecast. In this concise contribution, we demonstrate that three alkyls namely branched alkyl 2-butyloctyl (2BO), long linear alkyl n-dodecyl (C12), and double-short linear alkyl n-hexyls (DC6) incorporated into the side chains of large bandgap polymer donor PBDT-TTz can induce considerable, of significance, and different electronic, optical, and morphological parameters. Systematic studies shed light on the critical role of the double-short linear alkyl n-hexyls (DC6) in (i) producing large ionization potential value, (ii) increasing propensity of the polymer to order along the π-stacking direction, (iii) generating polymer crystallites with more preferential "face-on" orientation, consequently, (iv) improvement of carriers transportation, (v) suppression of charge recombination in all-polymer devices. In parallel, we unearth that the PBDT-TTz with double-short linear alkyl n-hexyls (DC6) represents highest efficiency of 8.3%, whereas, the other two PBDT-TTz analogues (2BO, C12) yield efficiencies of less than 3% in optimized all-polymer solar cells. Though branched or long linear alkyl side chains (2BO, C12) have been applied to provide the solution processability of conjugated polymers, motifs bearing multiple short linear alkyl substituents (DC6) are proved critical to the development of high performing polymers. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Adequate control of impulsive urges to act is demanded in everyday life but is impaired in neuropsychiatric conditions such as stimulant use disorder. Despite intensive research it remains unclear whether failures in impulse control are caused by impaired suppression of behavior or by the over invigoration of behavior by stimuli associated with salient incentives such as drugs, food, and money. We investigated failures in impulse control using functional magnetic resonance imaging (fMRI) to map the neural correlates of premature (impulsive) responses during the anticipation phase of the Monetary Incentive Delay (MID) task in healthy controls (HC), stimulant-dependent individuals (SDIs), and their unaffected first-degree siblings (SIB). We combined task-based fMRI analyses with dynamic causal modeling to show that failures of impulse control were associated with interactions between cingulo-opercular and dorsal striatal networks regardless of group status and incentive type. We further report that group-specific incentive salience plays a critical role in modulating impulsivity in SDIs since drug-related incentives specifically increased premature responding and shifted task modulation away from the dorsal striatal network to the cingulo-opercular network. Our findings thus indicate that impulsive actions are elicited by salient personally-relevant incentive stimuli and those such slips of action recruit a distinct fronto-striatal network. © 2020 The Authors.

Examples of forced sterilisation include the Nazis against Jewish, Roma and Sinti peoples and the Imperial Japanese Army in Korea during the Second World War, its historic use against Native Americans in the United States and more recent practice in Peru and the First Nations people in Canada.

Here we explore computationally how pressures below 300 GPa affect the fluorination of several transition metals. A plethora of new structural phases are predicted along with the possibility for synthesizing four unobserved compounds TcF7 , CdF3 , OsF8 , and IrF8 . The Ir and Os octaflourides are both predicted to be stable as quasi-molecular phases with an unusual cubic ligand coordination, and both compounds formally correspond to a high oxidation state of +8. Electronic-structure analysis reveals that otherwise unoccupied 6p levels are brought down in energy by the combined effects of pressure and a strong ligand field. The valence expansion of Os and Ir enables ligand-to-metal F 2p→M 6p charge transfer that strengthens M-F bonds and decreases the overall bond polarity. The lower stability of IrF8 , and the instability of PtF8 and several other compounds below 300 GPa, is explained by the occupation of M-F antibonding orbitals in octafluorides with a metal-valence-electron count exceeding 8.
