On the other hand, new experimental observations and DFT modelling led us to propose that enantioconvergent azidation of tertiary bromides proceeded through dynamic kinetic resolution (DKR). The investigations particularly identified the crucial roles of base and water in the enantioconvergent process, supporting the proposal that tertiary bromide isomerizes in the presence of base and water through a S N 2X pathway . © 2020 WILEY-VCH Verlag GmbH & Co.

The effect of jet lag on intrinsic cortical function remains unclear. Twenty-two healthy individuals experiencing west-to-east jet lag flight were recruited. Brain structural and functional magnetic resonance studies, as well as psychological and neurohormonal tests, were carried out when participants returned from travel over six time zones and 50 days later when their jet lag symptoms had resolved. During jet lag, the functional brain network exhibited a small-world topology that was shifted toward regularity. Alterations during jet lag relative to recovery included decreased basal ganglia-thalamocortical network connections and increased functional connectivity between the medial temporal lobe subsystem and medial visual cortex. The lower melatonin and higher thyroid hormone levels during jet lag showed the same trend as brain activity in the right lingual gyrus. Although there was no significant difference between cortisol measurements during and after jet lag, cortisol levels were associated with temporal lobe activity in the jet lag condition. Brain and neuroendocrine changes during jet lag were related to jet lag symptoms. Further prospective studies are needed to explore the time course over which jet lag acts on the human brain. © 2020 The Authors.

The 1.9 μm column showed excellent kinetic performance, comparable to that of the superficially porous one. These two columns also exhibit flatter c-branches of the van Deemter curve compared to the 1.7 μm fully porous particles column, resulting in smaller loss of efficiency when they are operated at higher flow rates than the optimal ones. The independent evaluation of each contribution to band broadening has revealed that the difference in kinetic performance comes from the very small eddy dispersion contribution on the 1.9 μm column, surprisingly even lower than that of the superficially porous one. This finding suggests a very good packing of the monodisperse 1.9 μm column. On the other hand, the potential of 1.7 μm fully porous particles is completely broken down by the strong frictional heating effect already arising at relatively low flow rates.

In this descriptive qualitative research study, we interviewed thirty patients with heart failure to explore their psychological experiences with heart failure and the perceived associations between positive psychological constructs and adherence to physical activity, diet, and medication recommendations. Interviews were transcribed, then coded in NVivo using directed and conventional content analysis, and the Consolidated Criteria for Reporting Qualitative Research checklist was applied to report our findings. Participants spontaneously reported positive psychological constructs both during an acute phase of illness and three months later. Participants most commonly experienced gratitude, acceptance, connectedness, and faith in the setting of heart failure. In contrast, pride, determination, and hope were identified most frequently as playing a role in health behavior adherence. Finally, participants reported a reinforcing relationship between positive constructs and health behavior engagement. These findings suggest that interventions to boost positive constructs have the potential to improve well-being and health behavior adherence in patients with heart failure.

MATERIALS AND METHODS Sixty-four extracted premolars without root canal treatment were prepared and restored with occlusal veneers of two thicknesses (1.5 and 2.5 mm), using four different materials microhybrid composite (MC), fiber-reinforced microhybrid composite (FMC), heat-pressed lithium disilicate ceramic (HPC), and computer-aided design/computer-aided manufactured lithium disilicate ceramic (CCC). The specimens underwent thermocycling and cyclic mechanical fatigue loading, and were then subjected to fracture testing, with loads at failure recorded as fracture load. Wear and surface roughness were recorded before and after fatigue loading. Results were analyzed using one-way ANOVA, two-way ANOVA (α = 0.05). RESULTS All specimens survived thermal cycling and cyclic mechanical fatigue loading. At 1.5-mm thickness, the mean fracture load of FMC was highest (3926.48 ± 556.54 N), while that of CCC was highest (3066.45 ± 559.94 N) at 2.5 mm. Regardless of thickness, the fracture load of CCC was higher than that of HPC (P = 0.004 and P = 0.023). The wear of MC and FMC was significantly higher than those of HPC and CCC (P≤0.001), but was similar in terms of the wear rate of tooth enamel. HPC exhibited the lowest surface roughness after fatigue loading (P≤0.001). CONCLUSION All tested occlusal veneers exhibited a fracture load considerably exceeding the maximum occlusal force in the posterior dentition. When the attainable space for restoration varies, different occlusal veneer materials should be considered. The surface wear and roughness also need to be considered when selecting materials.

The introduction of a strong electron donor to the BODIPY core via a phenyl linker combined with the twisted arrangement between the donor and the BODIPY acceptor is essential for reducing the energy gap between the lowest singlet excited state and the lowest triplet state (∆ E ST ), leading to a significant enhancement in the intersystem crossing (ISC) of the BODIPYs. Remarkably, the BDP-5 with the smallest ∆ E ST (≈0.44 eV) exhibited excellent singlet oxygen generation capabilities in both organic and aqueous solutions. BDP-5 also displayed bright emission in the far-red/near-infrared region in the condensed states. More importantly, both in vitro and in vivo studies demonstrated that BDP-5 NPs displayed a high potential for photodynamic cancer therapy and bioimaging. © 2020 WILEY-VCH Verlag GmbH & Co.

Following an approach that is reminiscent of covalent methodologies, we study here, for the first time, the mechanism of G-quadruplex formation in organic solvents. Our results support a reaction pathway in which the cation shifts first the equilibrium towards a G-quartet transient intermediate, which then acts as a template in the formation of the G-quadruplex product. © 2020 WILEY-VCH Verlag GmbH & Co.

The discovery of twist variations even in a single amyloid fibril is reported the fibril can vary its twist extents in response to the underlying nanopatterned surfaces by keeping its neighboring crossover sections right above the periodic nanodomains and tuning the distance between neighboring crossover sections based on either the periodic nanodomain distance or the fibril contour direction. This nanopattern-induced twist polymorphism arises from the fibril's two edges, exhibiting different hydrophobic interactions with the periodic nanodomains, as demonstrated by simulation studies. This work contributes to the understanding of surface effects on twist polymorphism in amyloid fibril structures that may be important to fibril polymorphism in amyloid pathologies and bioapplications of amyloid fibrils. © 2020 WILEY-VCH Verlag GmbH & Co.

Raman spectra of these polymers show a structural fingerprint of the polyene backbone which, in combination with its helical orientation, makes them great candidates to study their helical structure by Raman Optical Activity (ROA). Four different well-known poly(phenylacetylene)s adopting different scaffolds and ten different helical senses have been prepared. For all of these, Raman and ROA spectra were recorded which allows us to establish ROA spectrum/helical sense relationships a right-handed orientation of the polyene backbone (P helix ) produces a triplet of negative ROA bands, whereas a M helix produces a positive triplet ROA pattern. Raman and ROA spectra of each polymer exhibited the same profile and the sign of the ROA spectrum was opposite to the lowest energy ECD band, thus indicating a resonance effect. Resonance ROA appears then as a useful selective indicator of the helical sense of poly(phenylacetylene)s, especially for those showing an extra Cotton band in the ECD spectrum. In these cases, a wrong helical sense is assigned based on ECD, while ROA alerts of this misassignment. © 2020 WILEY-VCH Verlag GmbH & Co.

CAPE displays antitumour function; therefore, evaluating the antitumour effect of its analog with higher stability and membrane permeability is worthwhile. We first investigated the antitumour activity of compound 5A. We found that compound 5A significantly inhibited the proliferation of tumor cells and showed low cytotoxicity in normal cells. Furthermore, compound 5A was found to induce the cell cycle arrest and apoptosis of CNE2 cells. Through the prediction of SwissTargetPrediction and subsequent confirmation, epidermal growth factor receptor (EGFR) was identified as a target of compound 5A. Compound 5A also influenced the expression of genes downstream of EGFR in nasopharyngeal carcinoma (NPC) cells. Based on these findings, compound 5A inhibits the proliferation of NPC cells by targeting EGFR and may become a new candidate compound for NPC treatment.
