METTL14 facilitates the process of sexual reversal via m6A RNA methylation in Pelodiscus sinensis.

The Chinese soft-shelled turtle (Pelodiscus sinensis) demonstrates noteworthy sexual dimorphism, where the males grow more rapidly and significantly larger than females under equivalent conditions. Estradiol (E2) administration can catalyze transformation from male to pseudo-female (PF), during which m6A RNA methylation undergoes considerable alterations. Nevertheless, the function of m6A methylation, specifically, the methyltransferase 14, N6-adenosine-methyltransferase non-catalytic subunit gene (METTL14) during this sex reversal process remains unclear.

Adjuvant PD-1 Blockade With Camrelizumab for Nasopharyngeal Carcinoma: The DIPPER Randomized Clinical Trial.

Importance: Approximately 20% to 30% of patients with locoregionally advanced nasopharyngeal carcinoma (NPC) experience disease relapse despite definitive chemoradiotherapy. The programmed cell death 1 (PD-1) blockade camrelizumab has demonstrated considerable value in recurrent or metastatic NPC, while its role in locoregionally advanced NPC is unclear.

Objective: To evaluate the efficacy and safety of adjuvant camrelizumab for patients with locoregionally advanced NPC.

Liquid-Assisted Grinding Enables Efficient Ni-Catalyzed, Mn-Mediated Denitrogenative Cross-Electrophile Coupling of Benzotriazinones with Benzyl Chlorides.

An efficient and air-tolerant Ni-catalyzed denitrogenative cross-electrophile coupling of benzotriazinones with benzyl chlorides has been developed via liquid-assisted grinding by using Mn powders as reductant and DMF as assisting liquid in the presence of anhydrous calcium chloride. Scope and limitations of the protocol to access diarylmethanes have been demonstrated with more than 20 examples, showing acceptable tolerance to functional group and steric hindrance. Although electron-withdrawing substituents on benzotriazinone or benzyl counterparts decrease the yields significantly, a series of N-alkyl-2-benzylbenzamides, diarylmethanes bearing an ortho-carbamoyl aryl group, could be obtained in modest to good yields.

Exploring the neurotoxic effects of cylindrospermopsin in early development of zebrafish: An integrated impact of oxidative stress, inflammatory response, and apoptosis.

The increasing global spread of cyanobacteria and their toxin Cylindrospermopsin (CYN) is a growing concern.This study aimed to examine the toxic effects of CYN on the early neurodevelopment of zebrafish, and to identify the underlying mechanisms. The findings indicated that zebrafish exposed to varying concentrations of CYN exhibited general developmental toxicity, including typical malformations, diminished embryonic movement, and shortened body length.

Multidependency Graph Convolutional Networks and Contrastive Learning for Drug Repositioning.

The goal of drug repositioning is to expedite the drug development process by finding novel therapeutic applications for approved drugs. Using multifeature learning, different computational drug repositioning techniques have recently been introduced to predict possible drug-disease relationships. Nevertheless, current graph-based methods tend to model drug-disease interaction relationships without considering the semantic influence of node-specific side information on graphs.
