Electroacupuncture alleviates diabetic peripheral neuropathy through modulating mitochondrial biogenesis and suppressing oxidative stress.

Background: Peripheral neuropathy caused by diabetes is closely related to the vicious cycle of oxidative stress and mitochondrial dysfunction resulting from metabolic abnormalities. The effects mediated by the silent information regulator type 2 homolog-1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) axis present new opportunities for the treatment of type 2 diabetic peripheral neuropathy (T2DPN), potentially breaking this harmful cycle.

Aim: To validate the effectiveness of electroacupuncture (EA) in the treatment of T2DPN and investigate its potential mechanism based on the SIRT1/PGC-1α axis.

A statistical framework for multi-trait rare variant analysis in large-scale whole-genome sequencing studies.

Large-scale whole-genome sequencing (WGS) studies have improved our understanding of the contributions of coding and noncoding rare variants to complex human traits. Leveraging association effect sizes across multiple traits in WGS rare variant association analysis can improve statistical power over single-trait analysis, and also detect pleiotropic genes and regions. Existing multi-trait methods have limited ability to perform rare variant analysis of large-scale WGS data.

Sodium arsenite induces islets β-cells apoptosis and dysfunction via SET-Rac1-mediated cytoskeleton disturbance.

Sodium arsenite (NaAsO), the most common form of inorganic arsenic prevalent in the environment, has been closely linked to islet β-cell dysfunction, a critical pathological hallmark of type 2 diabetes (T2D). Even though apoptosis plays a pivotal role in arsenic-induced islet β-cell dysfunction, the explicit underlying mechanisms remain elusive. Here, we have identified that the SET-Rac1 signaling pathway is instrumental in the apoptosis and dysfunction of islet β-cells induced by NaAsO.

Immunosuppressant nonadherence profile in kidney transplant recipients and the impact of medication adherence on transplant outcomes.

Background: Despite the fact that 1-year graft and recipient survival rates are above 90% in most transplant centers, improving long-term graft survival remains an important challenge. Immunosuppressant nonadherence has been recognized as one of the important risk factors for long-term graft failure. Understanding the modifiable correlates and risk factors for medication non-adherence is essential to develop interventions to improve adherence and thus long-term transplantation outcomes.

Integrated Transcriptomic and Metabolomic Analyses Reveal Changes in Aroma- and Taste-Related Substances During the Withering Process of Black Tea.

Withering is one of the major processing steps critical for the quality of black tea. In this study, we investigated the mechanisms underlying the physicochemical changes in metabolites and gene expression during the withering process of black tea using metabolomic and transcriptomic approaches, respectively. Based on gas chromatography/mass spectrometry non-targeted metabolomic approaches (GC-MS) and ultra-high performance liquid chromatograph-tandem mass spectrometry (UHPLC-MS/MS), a total of 76 volatile compounds and 160 non-volatile compounds were identified from tea leaves, respectively.

Impact of grain boundaries on the electronic properties and Schottky barrier height in MoS@Au heterojunctions.

Using density functional theory (DFT) calculations we thoroughly explored the influence of grain boundaries (GBs) in monolayer MoS composed of S-polar (S5|7), Mo-polar (Mo5|7), and (4|8) edge dislocation, as well as an edge dislocation-double S vacancy complex (S4|6), and a dislocation-double S interstitial complex (S6|8), respectively, on the electronic properties of MoS and the Schottky barrier height (SBH) in MoS@Au heterojunctions. Our findings demonstrate that GBs formed by edge dislocations can significantly reduce the SBH in defect-free MoS, with the strongest effect for zigzag (4|8) GBs (-20% reduction) and the weakest for armchair (5|7) GBs (-10% reduction). In addition, a larger tilt angle in the GBs leads to a more pronounced decrease in the SBH, suggesting that the modulation of SBH in the MoS@Au heterostructure and analogous systems can be accomplished by GB engineering.

Environmentally Stable Reversible Cavitand Molecular Switches Based on the Excimer of Perylene.

Environmentally stable novel flexible bisperylene resorcin[4]arene molecular switch cavitand B and the corresponding rigid cavitand A were synthesized and a single crystal was obtained. Spectroscopic analysis revealed the formation of an excimer of perylene within the cavitand. The presence of flexible chains in cavitand B confers a high degree of environmental stability, rendering its fluorescence unaffected by external factors such as pH and temperature variations.

Hessian-based mixed-precision quantization with transition aware training for neural networks.

Model quantization is widely used to realize the promise of ubiquitous embedded deep network inference. While mixed-precision quantization has shown promising performance, existing approaches often rely on time-consuming search process to determine the optimal bit configuration. To address this, we introduce Hessian-based Mixed-Precision Quantization Aware Training(HMQAT) to decrease the search overhead of bit configuration.
