The apical membrane antigen-1 (AMA-1) is a crucial target for malaria management and prevention strategies. While the immunogenicity of AMA-1 has been extensively studied for Plasmodium falciparum and Plasmodium vivax, there is a notable scarcity of information for Plasmodium malariae. In this study, recombinant PmAMA-1 was expressed in Escherichia coli, and its integrity was confirmed via western blotting and indirect immunofluorescence assays. Immunization of BALB/c mice with rPmAMA-1 emulsified in Freund's adjuvant resulted in significantly elevated specific IgG antibodies, predominantly IgG1. The immune response exhibited Th1, Th2, and Th17 phenotypes, with a notable Th1 bias. Antisera from immunized mice effectively recognized native PmAMA-1 on P. malariae. These results suggest that PmAMA-1 is a promising target for both vaccine development and diagnostic applications for P. malariae infections, offering dual preventive and diagnostic benefits in malaria control.

Objective: To investigate the clinical effect of transposition of gracilis muscle flap in repairing urethral perineal fistula after Miles operation.
Methods: The clinical data of 3 patients with urethral perineal fistula treated in the Second Affiliated Hospital of Zhejiang University from September 2023 to November 2024 were analyzed retrospectively. All patients were male, aged from 59 to 68 years (mean 63 years).

Introduction: Cystic fibrosis (CF) is a monogenic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a Cl/HCO ion channel located at the apical plasma membrane (PM) of epithelial cells. CFTR dysfunction disrupts epithelial barrier integrity, drives progressive airway remodelling and has been associated with epithelial-to-mesenchymal transition (EMT), a process in which cells lose epithelial properties and acquire mesenchymal characteristics. We previously demonstrated that mutant CFTR directly drives partial EMT, independently of secondary events such as bacterial infection or inflammation.

The in vitro intestinal permeability of straight- and branched-chain parabens has not been extensively investigated. Sixteen parabens were tested in the Caco-2 assay. Passive diffusion was measured using PAMPA.

Aquaporins (AQPs) are essential membrane channel proteins in plants, with tonoplast intrinsic proteins (TIPs) representing a subfamily of AQPs that play a crucial role in responses to abiotic stress. Here, we identified 10 BpTIP genes in birch (Betula platyphylla), distributed across seven chromosomes, all of which contain conserved major intrinsic protein domains. Polyethylene glycol-induced drought simulation induced the expression of all BpTIP genes except BpTIP5; 1.

Epithelial cells are tightly connected to one another by intercellular junctions which prevent much of their motility, and have distinct apical-basal cell polarity, with their basal pole facing the basement membrane; they form mono- or multilayered sheet-like structures, and establish the borders of tissues and organs. In contrast, mesenchymal cells fill the spaces delimitated by other tissues, do not form stable contacts with other cells, are embedded within the extracellular matrix with which their entire surface interacts, and have definite locomotory capabilities. Epithelial-mesenchymal transition (EMT) occurs when an epithelium loses its distinguishing characteristics, and acquires mesenchymal traits.
