CONCLUSIONS IDD were present in the last common ancestor of Streptophyta. On land, IDD duplicated extensively originating ten lineages. Later, IDD were recruited by angiosperms where they diversified greatly in number; C-terminal and expression patterns accompanying important aspects of plant body evolution.This study provides a solid framework of the orthology relations of green land plant IDD transcription factors, thus increasing the accuracy of ortholog identification in model and non-model species and facilitating the identification of agronomically important genes related to plant metabolism and development. © The Author(s) 2020.

The past several decades of stress research regarding sexual minority men's HIV-risk behaviors has almost exclusively focused on the influence of stress emanating from outside the gay community (e.g., stigma-related stress, or minority stress, such as heterosexist discrimination). However, recent evidence suggests that sexual minority men also face stress from within their own communities. PURPOSE We sought to examine whether stress from within the gay community, or intraminority gay community stress, might influence sexual minority men's risk behaviors, including HIV-risk behaviors, over-and-above more commonly examined stressors affecting this risk. METHODS We tested whether intraminority gay community stress was associated with sexual minority men's HIV-risk behaviors in a large national survey of sexual minority men (Study 1), and experimentally tested intraminority gay community stress's impact on behavioral risk-taking and attitudes toward condom use (Study 2). RESULTS Self-reported exposure to intraminority gay community stress was positively associated with HIV-risk behaviors when accounting for the effects of several commonly examined minority stressors and general life stress (Study 1). Participants who were rejected from an online group of other sexual minority men evidenced greater risk-taking in a subsequent task and reported fewer benefits of condom use than participants who were accepted by the online group, when accounting for state affect (Study 2). CONCLUSIONS Sexual minority men's experiences of stress and rejection stemming from their own community may be an important and overlooked predictor of HIV infection and transmission. © Society of Behavioral Medicine 2020. click here All rights reserved.

In this context, this work focuses on the introduction of an S-linkage into arabinoxylan oligosaccharides (AXs) in order to obtain a small collection of synthetic tools for the study of AXs degrading enzymes. The key step for the introduction of the S-glycosidic linkage involved anomeric thiol S-alkylation of an orthogonally protected l-arabinopyranoside triflate. The resulting S-linked disaccharide was subsequently employed in a series of glycosylation reactions to obtain a selectively protected tetrasaccharide. This could be further elaborated through chemoselective deprotection and glycosylation reactions to introduce branching l-arabinofuranosides.There are more than 200 two-dimensional (2D) networks with different topologies. The structural topology of a 2D network defines its electronic structure. Including the electronic topological properties, it gives rise to Dirac cones, topological flat bands and topological insulators. In this Tutorial Review, we show how electronic properties of 2D networks can be calculated by means of a tight-binding approach, and how these properties change when 2nd-neighbour interactions and spin-orbit coupling are included. We explain how to determine whether or not the resulting electronic features have topological signatures by calculation of Chern numbers, Z2 invariants, and by the nanoribbon approach. This tutorial gives suggestions how such topological properties could be realized in explicit atomistic chemical 2D systems made of molecular frameworks, in particular in 2D polymers, where the edges and vertices of a given 2D net are substituted by properly selected molecular building blocks and stitched together in such a way that long-range π-conjugation is retained.Here, we demonstrate for the first time the construction of covalent organic framework (COF) capsules with nanostructured surfaces, which combine advantages of highly accessible surface area, excellent light absorbance, and efficient separation of photogenerated electron-hole pairs. The COF capsules exhibit high activity and selectivity for photocatalytic oxidation under mild conditions.One of the most encountered obstacles for utilizing nano-sized vehicles to implement the in vivo delivery of nucleic acid drugs (NADs) is the possible steric hindrance caused by their intrinsic size and charge. In this work, we added Ca2+ for the pH triggered self-assembly process of H-apoferritin (HFn), to neutralize negative charges and help siRNA condense during complexation and particle formation. As expected, the internalization efficiency of siRNA in HFn particle formation could be enhanced 1.65-fold, compared with that without incorporated Ca2+. Furthermore, the calcification that occurred within the cavity of HFn particles endows them with endosomal escape capability, which could explain their contribution to the demonstrated in vitro and in vivo gene silencing effect achieved by the internalized siRNA. Thus, this Ca2+ participating self-assembly process of a protein nanostructure would lead to advanced internalization efficiency for NAD therapy.
