MEK3/MEK6, and MEK4/MKK4. Notably, TRB3 knockout reduced the accumulation of p62 and LC3 (P less then 0.05 for both), decreased the phosphorylation of JNK (P = 0.0015), and increased p38 phosphorylation (P = 0.0021). CONCLUSIONS TRB3 knockout in mice attenuated muscle fibre atrophy and reduced skeletal muscle fibrosis by increasing autophagy and inhibiting the MAPK signalling pathway. Correspondingly, in aged knockout mice, exercise capacity was improved. Interfering with TRB3 expression in aged skeletal muscles may serve as a target for the prevention and treatment of age-related sarcopenia. © 2020 The Authors.

Phenolic hydroxyl and carboxylic acid groups along with other functionalities provide technical lignins with reactivity and amphiphilic character. Many different lignins have been used as a functional agent to facilitate synthesis and stabilization of inorganic materials. Here we review the use of lignin in synthesis and chemistry of inorganic materials in selected applications with relevance to sustainable energy and environmental fields. In essence, the combination of lignin and inorganic materials creates an interface between soft and hard materials. It is in many occasions either this interface or the external lignin surface that provides functionality to the hybrid and composite materials. We close with an outlook of future directions for this research field that bridges inorganic and lignin materials for a more sustainable future. © 2020 WILEY-VCH Verlag GmbH & Co.

X-ray structure analysis of the bis( n- butylthio) derivative ( 1c ) revealed that the molecules are stacked in a head-to-tail manner. In the cyclic voltammetry, the bis( n -hexylthio)- 1 ( 1d ) exhibits six-pairs of one-electron transfer waves corresponding to the formation of both reduction and oxidation states from -2 to +4. The unsubstituted and bis(methylthio) derivatives of 1 and 2 work as a positive electrode active material for the rechargeable batteries, and several of whose energy densities exceed 800 mWh g -1 . The bis(methylthio)- 2 ( 2b ) also functions as a positive electrode material for the rechargeable sodium ion battery. © 2020 WILEY-VCH Verlag GmbH & Co.

We aimed to evaluate the in vitro biocompatibility of the membrane in human gingival fibroblasts and the capability to induce cell adhesion, migration, differentiation and improving the production of the extracellular matrix. BHM and Mucograft® collagen matrix (MCM) membranes were punched into 6 mm diameter round discs and placed in 96-well plates. Human primary gingival fibroblasts were seeded on the membranes or tissue culture plastic (TCP) serving as the control. Cell proliferation/viability and morphology were evaluated after 3, 7, and 14 days of culture by cell counting kit (CCK)-8 assay and scanning electron microscopy, respectively. Additionally, the gene expression of transforming growth factor (TGF)-β1, focal adhesion kinase (FAK), collagen type 1 (Col1), alpha-smooth muscle actin (α-SMA), and fibroblasts growth factor (FGF)-2 was analyzed at 3, 7, and 14 days of culture by qPCR. Cell proliferation on BHM was significantly higher than on MCM and similar to TCP. Gene expression of TGF-β1, FAK, Col1, and α-SMA were significantly increased on BHM compared to TCP at most investigated time points. However, the gene expression of FGF-2 was significantly decreased on BHM at Day 7 and recovered at Day 14 to the levels similar to TCP. The finding of this study showed that BHM is superior for gingival fibroblasts in terms of adhesion, proliferation, and gene expression, suggesting that this membrane may promote the healing of soft periodontal tissue. © 2020 The Authors.

A total of 89 subjects were divided into two groups men with isolated teratozoospermia (n = 69) and men with normal semen parameters (n = 20) as controls. Sperm DNA breaks were determined by using acridine orange staining. The proportion of viable spermatozoa with mitochondrial transmembrane depolarization was detected by fluorescence microscopy through the use of MitoPTJC-1 staining method. Bivariate Annexin V/6-CFDA analysis was then set out in order to measure the percentage of both viable and dead spermatozoa with phosphatidylserine (PS) externalization. Erastin Seminal antioxidant profile (reduced glutathione (GSHr); oxidized glutathione (GSSG); glutathione S-transferase (GST)) and total protein sulfhydryl (P-SH) concentrations were measured spectrophotometrically. Men with isolated teratozoospermia, when compared to condeath-mediated DNA breaks in teratozoospermic semen. © 2020 American Society of Andrology and European Academy of Andrology.The proliferation of increasingly more sophisticated analytical separation systems, often incorporating increasingly more powerful detection techniques, such as high-resolution mass spectrometry, causes an urgent need for highly efficient data-analysis and optimization strategies. This is especially true for comprehensive two-dimensional chromatography applied to the separation of very complex samples. In this contribution, the requirement for chemometric tools is explained and the latest developments in approaches for (pre-)processing and analyzing data arising from one- and two-dimensional chromatography systems are reviewed. The final part of this review focuses on the application of chemometrics for method development and optimization. © 2020 The Authors.
