M5 cladding has emerged as a prominent fuel cladding material due to its excellent corrosion resistance. The dissolution behavior of M5 cladding is critical in both the initial cleaning stage and the reprocessing of spent fuel cladding. This study investigated the dissolution of M5 cladding in hydrofluoric-nitric (HF-HNO) mixed acid at varying concentrations.

Due to a series of factors such as variations in powder preparation methods, the kinetic parameter data for its dissolution in nitric acid solution exhibit dispersion. This study investigates the UO powder which underwent oxidation and volatilization at 850 °C. The particle size of the UO powder prior to dissolution was measured, and the surface area during dissolution was calculated under certain assumptions.

Inorganic semiconductor materials are crucial for modern technologies, but their brittleness and limited processability hinder the development of flexible, wearable, and miniaturized electronics. The recent discovery of room-temperature plasticity in some inorganic semiconductors offers a promising solution, but the deformation mechanisms remain controversial. Here, we investigate the deformation of indium selenide, a two-dimensional van der Waals semiconductor with substantial plasticity.

Article Synopsis
  • The study examines how different thicknesses of mulch film (MF) affect soil properties and the structure of the microorganism community in tobacco cultivation.
  • Results showed that thicker MF (0.010 mm) significantly improved tobacco growth traits like height and leaf weight compared to unmulched fields.
  • The research found that thicker MF increased beneficial soil properties (like organic matter and nitrogen) but reduced soil temperature and the soil's ability to degrade pollutants, altering microbial community functions.

Article Synopsis
  • Understanding the immune mechanisms in liver transplantation is complicated, especially the role of tissue-resident memory T cells (TRMs).
  • The study uses a multi-omics approach, analyzing samples from 17 humans and 16 mice, finding significant insights into T cell behavior.
  • There’s a noticeable rise in CD8 TRMs during graft rejection, marked by various activation markers, suggesting they could serve as biomarkers for rejection and help develop better treatment methods for transplant success.

Purpose: The present study aimed to identify the optimal design of the unicompartmental femoral component through parameter analysis and stability evaluation.

Methods: A finite element (FE) analysis was applied to analyse and adjust the parameter combinations of the anterior tilt angle of the posterior condyle resection surface, the position of the peg, the length of the peg and the inclination angle of the peg, resulting in 10 different FE models. Setting three knee flexion angles of 8.

Background: Traumatic brain injury (TBI) is 1 of the leading causes of death in all age groups globally. Understanding TBI causative factors and early interventions that may result in poor outcomes plays an important role in decreasing the mortality and disability associated with TBI.

Methods: In this retrospective case-control study, we collected electronic case data from patients with TBI who visited our hospital between 2018 and 2022.

GeMnTe adopts a cubic rock salt structure and is a promising mid-temperature thermoelectric material. The pair distribution function analysis of neutron total scattering data, however, indicates that GeMnTe is locally distorted from the ideal rock salt structure with Ge cations being discordant and displaced ∼0.3 Å off the octahedron center.

Background: Liver transplantation is one of the most effective treatments for end-stage liver disease. Split liver transplantation (SLT) can effectively improve the utilization efficiency of grafts. However, split liver transplantation still faces shortcomings and is not widely used in surgery.

Rejection is still a critical barrier to the long-term survival of graft after liver transplantation, requiring clinicians to unveil the underlying mechanism of liver transplant rejection. The cellular diversity and the interplay between immune cells in the liver graft microenvironment remain unclear. Herein, we performed single-cell RNA sequencing analysis to delineate the landscape of immune cells heterogeneity in liver transplantation.

Background: For liver transplant (LT) recipients, the liver CYP3A5 metabolic enzymes are determined by the donor's genes, whereas the intestinal enzymes are encoded by the recipient's genes. This combinational form confuses the metabolism of tacrolimus (Tac) in vivo. This retrospective study was conducted to investigate the combined effects of donor-recipient CYP3A5 genotype on tacrolimus pharmacokinetics in Chinese LT adult patients.

Hepatocellular carcinoma (HCC) is a primary malignancy of the liver and occurs predominantly in patients with underlying chronic liver disease and cirrhosis. Accumulating studies have revealed that microRNAs (miRNAs) play a critical role in the development and progression of HCC. Through microarray-based gene expression profiling of HCC, miR-370, and BEX2 were identified in HCC.

Water-soluble polysaccharides (DCCP, DCPP) were extracted from the stems of Dendrobium chrysotoxum using boiling water and ultrasound. DCPP were successively purified by chromatography on DEAE-Cellulose-52 and Sephadex G-200 column, giving three major polysaccharide fractions termed DCPP-I, DCPP-I-a and DCPP-II. Among these fractions, DCPP-I-a exhibited the highest abundance (79.
