ADAR1 Promotes the Progression and Temozolomide Resistance of Glioma Through p62-Mediated Selective Autophagy.

Background: Resistance to temozolomide (TMZ) remains is an important cause of treatment failure in patients with glioblastoma multiforme (GBM). ADAR1, as a member of the ADAR family, plays an important role in cancer progression and chemotherapy resistance. However, the mechanism by which ADAR1 regulates GBM progression and TMZ resistance is still unclear.

Effect of music therapy on emotional resilience, well-being, and employability: a quantitative investigation of mediation and moderation.

This study explores the impact of music therapy on emotional resilience, well-being, and employability.

Endometriosis does not impact aneuploidy rates of products of conception in IVF population.

It has been debated whether endometriosis (EMS) adversely affects oocyte quality, potentially leading to a higher incidence of genetically unbalanced embryos or other egg factors that affect the developmental potential. In this study, we explored the effects of endometriosis on risk of chromosomally aberrant in miscarried products of conception (POC) after assisted reproductive treatment (ART), including fresh and frozen cycles. Miscarried POCs were collected from EMS patients (N = 102) and non-EMS patients (N = 441).

Integrative genetics and multiomics analysis reveal mechanisms and therapeutic targets in vitiligo highlighting JAK STAT pathway regulation of CTSS.

Vitiligo is a complex autoimmune disease characterized by the loss of melanocytes, leading to skin depigmentation. Despite advances in understanding its genetic and molecular basis, the precise mechanisms driving vitiligo remain elusive. Integrating multiple layers of omics data can provide a comprehensive view of disease pathogenesis and identify potential therapeutic targets.

Degradation of Aflatoxin B in Corn by Water-Assisted Microwave irradiation and its kinetic.

Aflatoxin B (AFB) is a highly toxic, carcinogenic, teratogenic, and mutagenic mycotoxin commonly found in corn. In this work, water-assisted microwave irradiation (WMI) was used to degrade AFB in corn, during which the influencing factors and kinetics of AFB degradation were also studied. The results showed that the degree of corn crushing, the heating rate of WMI, the temperature of WMI, the solid-liquid ratio, the initial content of AFB and the microwave power were all important factors affecting the degradation of AFB.

The investigation of the interaction of warangalone with transferrin as a therapeutic biological macromolecule and the formation of a protein-ligand nanocomplex with superior anticancer activity against lung cancer cells.

Though warangalone has shown anticancer properties against breast cancer cells, its colloidal stability and therapeutic index ought to be improved using a potential strategy, especially via protein-based (nano)carriers. In this research, transferrin was used as a plasma protein for the development of the warangalone-transferrin NPs. To investigate the mechanism underlying the formation of this complex, the interaction between warangalone and transferrin, as well as transferrin NPs, was analyzed using spectroscopic methods.

Facile manufacture of silver(I) complex/multilayer graphene composite for dynamic adsorption desulfurization.

The cyclic triangular complex - silver (I) 4-nitro-3,5-bis(trifluoromethyl)pyrazolate (Agpz) with super π-acidity shows great potential in adsorptive desulfurization (ADS) as a novel adsorbent, however, it fails to work well in the continue flow adsorption study. In order to improve its dynamic adsorption performance, a composite has been prepared by mixing Agpz and multilayer graphene (MG) in methanol. Based on the results of characterization by FT-IR, XPS, SEM, and so on, the optimal mass ratio of Agpz:MG in the synthesis is 0.

Efficient Second Harmonic Generation via Plasmonic-Photonic Mode Matching in Hybrid Waveguide.

Hybrid nonlinear plasmonic waveguides, characterized by a small mode area and large nonlinear susceptibility, present an intriguing and practical platform for the minimization of nonlinear photonic devices. Nevertheless, the intrinsic Ohmic loss associated with surface plasmon polaritons (SPPs) and modal dispersion imposes constraints on the effective interaction length and, consequently, the ultimate efficiency of nonlinear processes. In this study, we demonstrate an efficient second harmonic generation (SHG) within a hybrid plasmonic waveguide by leveraging SPP-like modes at the fundamental wave and photonic-like modes at the SHG under phase matching conditions.

Deciphering transcription activity of mammalian early embryos unveils on/off of zygotic genome activation by protein translation/degradation.

Quantification of transcription activities in mammalian preimplantation embryos is challenging due to a huge amount of maternally stored transcripts and paucity of research materials. Here, we investigate genome-wide transcription activities of mouse and human preimplantation embryos by quantifying elongating RNA polymerase II. Two transcriptional waves are identified in early mouse embryos, with summits at the 2-cell and 8-cell stages.
