Consequently, the focal adhesion areas were significantly decreased, resulting in impaired cell adhesion. © 2020 Wiley Periodicals, Inc.Chiral acyclic tertiary allylic alcohols are very important synthetic building blocks, but their enantioselective synthesis is often challenging. A major limitation in catalytic asymmetric 1,2-addition approaches to ketones is the enantioface differentiation by steric distinction of both ketone residues. In this communication we report the development of a catalytic asymmetric Meisenheimer rearrangement to overcome this problem, as it proceeds in a stereospecific manner. This allows for high enantioselectivity also for the formation of products in which the residues at the generated tetrasubstituted stereocenter display a similar steric demand. Low catalyst loadings were found to be sufficient and the reaction conditions were mild enough to tolerate even highly reactive functional groups such as an enolizable aldehyde, a primary tosylate or an epoxide. Our investigations suggest an intramolecular rearrangement pathway. © 2020 WILEY-VCH Verlag GmbH & Co.

Patterns of marine dispersal remain poorly understood, partly because dispersal may vary through time and often homogenizes allele frequencies. However, combining multiple types of natural tags can provide more precise dispersal estimates, and biological collections can help reconstruct dispersal patterns through time. We used SNP genotypes and otolith core microchemistry from archived collections of larval summer flounder (Paralichthys dentatus, n = 411) captured between 1989-2012 at five locations along the U.S. East coast to reconstruct dispersal patterns through time. Neither genotypes nor otolith microchemistry alone were sufficient to identify the source of larval fish. However, microchemistry identified clusters of larvae (n = 3-33 larvae/cluster) that originated in the same location, and genetic assignment of clusters could be made with substantially more confidence. We found that most larvae likely originated near a biogeographic break (Cape Hatteras) and that larvae were transported in both directions across this break. Larval sources did not shift north through time, despite the northward shift of adult populations in recent decades. Our novel approach demonstrates that summer flounder dispersal is widespread throughout their range, both on intra- and inter-generational timescales, and may be a particularly important process for synchronizing population dynamics and maintaining genetic diversity during an era of rapid environmental change. Broadly, our results reveal the value of archived collections and of combining multiple natural tags to understand the magnitude and directionality of dispersal in species with extensive gene flow.

Over the past few decades, hydrogenated amorphous silicon (a-SiH) has been widely utilized as a TFT channel material. More recently, to meet the requirement of new types of displays such as organic light-emitting diode displays, and also to overcome the performance and reliability issues of a-SiH, low-temperature polycrystalline silicon and amorphous oxide semiconductors have partly replaced a-SiH channel materials. Basic material properties and device structures of TFTs in commercial displays are explored, and then the potential of atomically thin layered transition metal dichalcogenides as next-generation channel materials is discussed. © 2020 WILEY-VCH Verlag GmbH & Co.

Studies that have examined pregnancy outcomes in women living with HBV have reported conflicting results in relation to the incidence of gestational diabetes (GDM). The aim of this study is to examine if gestational diabetes is more common in women with chronic HBV residing in a non-Asian country DESIGN Cross sectional study SETTING Victoria, Australia POPULATION All singleton births between 2009 and 2017 METHODS Poisson regression was performed to determine if gestational diabetes is more common in women with HBV compared to women without HBV taking into account other risk factors such as maternal age, body mass index, parity, and country of birth. MAIN OUTCOME MEASURE Gestational diabetes diagnosis in women with chronic HBV infection RESULTS For women with HBV, the unadjusted incidence risk ratio for GDM was 1.75 (95% CI 1.6, 1.9). After adjusting for region of birth, BMI, parity, age and smoking, the adjusted incidence risk ratio was 1.2 (95% CI 1.1, 1.3) The highest incidence (37.1%) of GDM was in women with HBV and a BMI of >40. CONCLUSIONS The findings from this study confirm an association between HBV and GDM. This article is protected by copyright.

Following our previous works based on diMe-cyclen framework, a second generation of cationic water-soluble lanthanide complexes based on a constrained cross-bridged cyclam macrocycle functionalized with donor-π-conjugated picolinate antennas has been prepared with europium(III) and ytterbium(III). Their spectroscopic properties were thoroughly investigated in various solvents and rationalized with the help of DFT calculations. A significant improvement is observed in the case of the Eu 3+ complex, while the Yb 3+ analogous conserve an excellent brightness in aqueous solvent. Two-photon (2P) microscopy imaging experiments on living T24 human cancer cells confirmed the spontaneous internalization of the probes and images with good signal-to-noise have been obtained in the classical NIR-to-visible configuration with Eu 3+ luminescent bioprobe and in the NIR-to-NIR with the Yb 3+ one. © 2020 WILEY-VCH Verlag GmbH & Co.
