CONCLUSIONS In general, the recommended strategies of the KMAP-BP were similar to those of other guidelines, but differed in terms of the emphasis on rapid effectiveness, which is often desirable in actual clinical situations. The major limitation of the KMAP-BP is that it is a consensus-based rather than an evidence-based tool. Nevertheless, it may confer advantages in actual clinical practice. © 2020 John Wiley & Sons A/S.

It was proposed to be a mixed-valent semiconductor, and later a topological Kondo insulator, and yet has a Fermi surface despite being an insulator. We propose a new and unified understanding of SmB6 centered on the hitherto unrecognized dynamical bonding effect the coexistence of two Sm-B bonding modes within SmB6 , corresponding to different oxidation states of the Sm. The mixed valency arises in SmB6 from thermal population of these distinct minima enabled by motion of B. Our model simultaneously explains the thermal valence fluctuations, appearance of magnetic Fermi surface, excess entropy at low temperatures, pressure-induced phase transitions, and related features in Raman spectra and their unexpected dependence on temperature and boron isotope. © 2020 Wiley-VCH Verlag GmbH & Co.

The occurrence of alternative nitrogenases has not been well-studied due to the discriminatory expression of the molybdenum nitrogenase and lack of comprehensive genomic data. This study reports on the genomic analysis of 87 unique species containing alternative nitrogenases sequences. The distribution of nitrogen fixing genes within these species from distinct taxonomic groups shows the presence of the minimum gene set required for nitrogen fixation, including catalytic and biosynthetic enzymes of the Mo-dependent system (NifHDKENB) and the varying occurrence of additional nif-dedicated components. These include NifS and NifU, found primarily in aerobic species, suggesting that these genes are necessary for accommodating the high demand for Fe-S clusters during aerobic nitrogen fixation. © 2020 WILEY-VCH Verlag GmbH & Co.

By synthesizing results from rainfall manipulation experiments across a range of biomes and environments, a new study by Paschalis et al. (2020) diagnoses current limitations in model structure, identifies new data needs, and provides lessons for future model development. This article is protected by copyright.

Here, we report a purification-free and highly efficient synthesis of thiobenzotriazolides of Fmoc-protected and orthogonally protected 20 naturally occurring amino acids including asparagine, glutamine, and histidine. The near-quantitative conversion to the respective thioamidated peptides on solid support demonstrates the robustness of the synthetic route. Furthermore, the unaltered incorporation efficiency of thiobenzotriazolides from their stock solution till 48 h suggests their compatibility toward automated peptide synthesis. Finally, utilizing an optimized cocktail of 2% DBU + 5% piperazine for fast Fmoc-deprotection, we report the synthesis of a thioamidated Pin1 WW domain and thioamidated GB1 directly on solid support. © 2020 European Peptide Society and John Wiley & Sons, Ltd.The relationship between the brain's structural wiring and the functional patterns of neural activity is of fundamental interest in computational neuroscience. We examine a hierarchical, linear graph spectral model of brain activity at mesoscopic and macroscopic scales. The model formulation yields an elegant closed-form solution for the structure-function problem, specified by the graph spectrum of the structural connectome's Laplacian, with simple, universal rules of dynamics specified by a minimal set of global parameters. The resulting parsimonious and analytical solution stands in contrast to complex numerical simulations of high dimensional coupled nonlinear neural field models. This spectral graph model accurately predicts spatial and spectral features of neural oscillatory activity across the brain and was successful in simultaneously reproducing empirically observed spatial and spectral patterns of alpha-band (8-12 Hz) and beta-band (15-30 Hz) activity estimated from source localized magnetoencephalography (MEG). This spectral graph model demonstrates that certain brain oscillations are emergent properties of the graph structure of the structural connectome and provides important insights towards understanding the fundamental relationship between network topology and macroscopic whole-brain dynamics. . © 2020 The Authors. Human Brain Mapping published by Wiley Periodicals, Inc.The oocyte is a complex cell that executes many crucial and unique functions at the start of each life. These functions are fulfilled by a unique collection of macromolecules and other factors, all of which collectively support meiosis, oocyte activation, and embryo development. This review focuses on the effects of oocyte components on developmental processes that occur after the initial stages of embryogenesis. These include long-term effects on genome function, metabolism, lineage allocation, postnatal progeny health, and even subsequent generations. Factors that regulate chromatin structure, genome programming, and mitochondrial function are elements that contribute to these oocyte functions. © 2020 Wiley Periodicals, Inc.
