Collectively, these findings demonstrated that Rac1 inhibition delayed the EPCs degeneration and its potential mechanism may be associated with Wnt/β-catenin pathway regulation, which may help us better understand the association between Rac1 and CEP degeneration and provide a promising strategy for delaying the progression of IVDD. © 2020 The Authors.

In this work, we investigated the B(ppy)Mes2 to borirane isomerization mechanisms in the three lowest electronic states (S0 , S1 , and T1 ) based on the complete active space self-consistent field (CASSCF) and its second-order perturbation (CASPT2) methods combined with time-dependent density functional theory (TD-DFT) calculations. Our results show that the photoisomerization in the S1 state is dominant, which is initiated by the cleavage of the B-Cppy bond. After overcoming a barrier of 0.5 eV, the reaction pathway leads to a conical intersection between the S1 and S0 states (S1 /S0 )x , from which the decay path may go back to the reactant B(ppy)Mes2 via a closed-shell intermediate (Int1-S0 ) or to the product borirane via a biradical intermediate (Int2-S0 ). Although triplet states are probably involved in the photoinduced process, the possibility of the photoisomerization in T1 state is very small owing to the weakly allowed S1 →T1 intersystem crossing and the high energy barrier (0.77 eV). In addition, we found the photoisomerization is thermally reversible, which is consistent with the experimental observations. © 2020 Wiley-VCH Verlag GmbH & Co.

The cationic and radical addition reactions between a dithiol and divinyl ether with oxyethylene units yielded amorphous poly(thioacetal)s and crystalline poly(thioether)s, respectively. Under high-dilution conditions, the cationic and radical reactions resulted in 16- and 18-membered cyclic thioacetal and thioether products, respectively. Furthermore, concurrent cationic and radical step-growth polymerizations were realized using PTSA under UV irradiation to produce polymers having both thioacetal and thioether linkages in the main chain. © 2020 Wiley-VCH Verlag GmbH & Co.

At 25°C, T. marneffei grows in a multicellular, filamentous hyphal form that can differentiate to produce dormant spores called conidia. These conidia are the likely infectious agent. At 37°C, T. marneffei grows as a uninucleate yeast that divides by fission. The yeast cells are the pathogenic form of this fungus. The protocols described here explain how to grow T. marneffei in the two vegetative growth forms in vitro, grow yeast cells inside mammalian macrophages, produce conidial stocks, and store strains both short and long term. © 2020 by John Wiley & Sons, Inc.

However, achieving high-efficiency energy storage and flexible chemical production simultaneously is still challenging. Herein, we proposed and realized a reversible hybrid aqueous Li-CO 2 battery integrating Li with aqueous phase, exhibiting not only a high operating voltage and energy density, but also highly selective HCOOH production simultaneously. CaMK inhibitor Based on a Li plate as the anode, NaCl solution as aqueous electrolyte, solid electrolyte Li 1.5 Al 0.5 Ge 1.5 P 3 O 12 (LAGP) as separator and Li + transporter, and a bifunctional Pd-based electrocatalyst as the cathode, the resulting battery possessed the high discharge voltage up to 2.6 V, the outstanding energy conversion efficiency higher than 80%, and the remarkable selectivity of CO 2 -to-HCOOH conversion up to 97%. The related reaction mechanism was proposed as CO 2 +2Li+2H + ⇋HCOOH+2Li + . © 2020 WILEY-VCH Verlag GmbH & Co.

In addition to an electron-donating Cp* ligand (Cp*=pentamethylcyclopentadienyl), the catalyst featured a proton-responsive pyridyl-benzimidazole-based N,N-bidentate ligand. Owing to the presence of a relatively electron-rich Co center, the reduced Co(I)-state was made prone to activate the electrophilic carbon center of CO2 . At the same time, the proton-responsive benzimidazole scaffold was susceptible to facilitate proton-transfer during the subsequent reduction of CO2 . The above factors rendered the present catalyst active toward producing CO as the major product over the other potential 2e/2H+ reduced product HCOOH, in contrast to the only known similar half-sandwich CpCo(III)-based CO2 -reduction catalysts which produced HCOOH selectively. The system exhibited a Faradaic efficiency (FE) of about 70% while the overpotential for CO production was found to be 0.78 V, as determined by controlled-potential electrolysis.
