Introduction: Training medical students requires objectives that are often translated into frameworks of competencies. Since the introduction of entrustable professional activities (EPAs), these tasks or 'units of professional practice', originally conceived for postgraduate training, define what residents must be prepared to do unsupervised. Nowadays, EPAs are also applied to undergraduate training, with the prospect of entering residency.

Doping of quantum antiferromagnets is an established approach to investigate the robustness of their ground state against the competing phases. Predictions of doping effects on the ground state of the Shastry-Sutherland dimer model are here verified experimentally on Mg-doped SrCu(BO). A partial incorporation of Mg on the Cu site in the SrCu(BO) structure leads to a subtle but systematic lattice expansion with the increasing Mg-doping concentration, which is accompanied by a slight decrease in the spin gap, the Curie-Weiss temperature, and the peak temperature of the susceptibility.

Background: Recipient's VEGF-A polymorphisms have been reported to be associated with the risk of acute allograft rejection. However, an association of the donor's VEGF-A gene polymorphism with rejection remained unelucidated till now.

Methods: In this study, VEGF-A gene SNPs at nine loci were analyzed in 160 kidney donors and recipients with rejection (rejectors, n = 80) and without rejection (non-rejectors, n = 80).

To eliminate electromagnetic pollution, it is a challenging task to develop highly efficient electromagnetic shielding materials that integrate microwave absorption (MA) performance with high shielding capability and achieve tunability in shielding performance. Asymmetrically structured aero/organo/hydrogels with a progressively changing concentration gradient of liquid metal nanoparticles (LMNPs), induced by gravity, are prepared by integrating the conductive fillers TiCT MXene and LMNPs into a dual-network structure composed of polyvinyl alcohol and cellulose nanofibers. Benefiting from the unique structure, which facilitates the absorption-reflection-reabsorption process of electromagnetic waves along with conductive fillers and the porous structure, three types of gels demonstrate efficient shielding performance.

It is heavily suggested that one gene polymorphism, rs12979860 (T/C), exerts influence on the outcome of HBV infection, with the rs12979860-T allele being classified as a risk predictor, and the rs12979860-C allele being classified as a protective one. This study investigated whether the rs12979860 gene polymorphism presented any association with the clinical severity for HBV carriers in an admixed population in Northern Brazil. A total of 69 samples were investigated from infected people from the city of Belém-Pará.

  • Diabetic macroangiopathy is a significant cause of death and disability among diabetic patients, with research needed on smooth muscle cell transformation and metabolic changes beyond just glucose and lipid issues.
  • The study utilized advanced sequencing techniques on tissue samples from diabetic patients to create a detailed spatial multiomics map, revealing the composition and functions of cells in calcified vascular regions.
  • Results indicate smooth muscle cells in diabetic patients can transform into various pro-inflammatory and specialized cell types, and that metabolic reprogramming is influenced by specific transcription factors and metabolic networks, highlighting the complexity of diabetes-related vascular changes.

Type 2 diabetes (T2DM) is characterised by insulin resistance and a relative shortage of insulin secretion. Tumour necrosis factor-α (TNF-α) plays an important role in insulin resistance by impairing insulin signal transduction. The variants of the TNF-α promoter region are considered to influence its transcription and are associated with the TNF-α level.
