First-principles prediction of intrinsic ferrovalley properties in Janus rare-earth PrXY (X ≠ Y = Cl, Br, I) monolayers.

In this work, using first-principles calculations, we predict a promising class of two-dimensional ferromagnetic semiconductors, namely Janus PrXY (X ≠ Y = Cl, Br, I) monolayers. Through first-principles calculations, we found that PrXY monolayers have excellent dynamic and thermal stability, and their band structures, influenced by magnetic exchange and spin-orbital coupling, exhibit significant valley polarization. Between and - valleys, the Berry curvature values are opposite to each other, resulting in the anomalous valley Hall effect.

Ultrathin 2D Cu-Porphyrin MOF Nanosheet Loaded FeO Nanoparticles As a Multifunctional Nanoplatform for Synergetic Chemodynamic and Photodynamic Therapy Independent of O.

In this study, we developed a multifunctional nanoplatform to address the limitations of strictly acidic pH for the Fenton reaction involving FeO and the low efficiency of mono treatments. The hybrid material, FeO@Cu-TCPP, was assembled through hydrophobic interactions of polyvinylpyrrolidone (PVP) coated on its surface. The efficiency of the Fenton reaction using FeO was significantly enhanced by the photo-Fenton process in the presence of Cu-TCPP.

Phosphorylation of Arabidopsis NRT1.1 regulates plant stomatal aperture and drought resistance in low nitrate condition.

Background: NITRATE TRANSPORTER 1.1 (NRT1.1) functions as a dual affinity nitrate transceptor regulated by phosphorylation at threonine residue 101 (T101).

Tuberculosis vaccines and therapeutic drug: challenges and future directions.

Tuberculosis (TB) remains a prominent global health challenge, with the World Health Organization documenting over 1 million annual fatalities. Despite the deployment of the Bacille Calmette-Guérin (BCG) vaccine and available therapeutic agents, the escalation of drug-resistant Mycobacterium tuberculosis strains underscores the pressing need for more efficacious vaccines and treatments. This review meticulously maps out the contemporary landscape of TB vaccine development, with a focus on antigen identification, clinical trial progress, and the obstacles and future trajectories in vaccine research.

A case report of hypospadias combined with polyorchidism.

Hypospadias is a common congenital malformation of the reproductive system; however, to date, no cases of hypospadias complicated by polyorchidism have been reported in the literature. This article reports a case of a 1-year-old boy presenting with hypospadias, who was also diagnosed with polyorchidism combined with cryptorchidism. Preoperative Doppler ultrasound revealed two testes on the right side, and an atrophic testis on the left.
