Microscopic lens changes are studied in mice (F1C57B1XCBA) depending on age and after ultraviolet (UV), gamma-irradiation and their combination. In all animals compared to young 3-months animals nonspecific changes due to aging were revealed: microvacuoles in cytoplasm of fiber cells, flattening of epithelial cells and nuclei fragmentation, swelling and confluence of cortical layer cells in anterior and posterior subcapsular zones. In epithelial cells the following changes were noted: nuclei polymorphism, cavities in a cell layer formation of multilayered structures of fibroblast-like cells and cell desquamation. Degree of nuclei vacuolization was significantly lower in groups with gamma- and gamma+UV-irradiation but higher in a group of UV exposure. The number of cells per unit area was significantly decreased in a group of gamma-irradiation after 7 and 10 months of exposure. Aging and UV exposure caused decrease of nuclei area, whereas affect of gamma-irradiation depended on proliferative capacity of cells: size of central cells increased and of peripheral cells reduced. Specific changes were not revealed for any of the factors.

Background: Bioinformatics analysis of hepatocellular carcinoma (HCC) expression profiles can aid in understanding its molecular mechanisms and identifying new targets for diagnosis and treatment.
Aim: In this study, we analyzed expression profile datasets and miRNA expression profiles related to HCC from the GEO using R software to detect differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRs).
Methods And Results: Common DEGs were identified, and a PPI network was constructed using the STRING database and Cytoscape software to identify hub genes.

Purpose: To report a case of biopsy-proven sarcoidosis in a patient with panuveitis and a positive interferon-gamma release assay (IGRA) from a non-endemic tuberculosis (TB) country.
Methods: Case report.
Results: A 26-year-old male from the United Arab Emirates (UAE) presented with granulomatous panuveitis characterized by mutton-fat keratic precipitates, anterior chamber and vitreous cells, and retinal vasculitis.

Background: Chronic obstructive pulmonary disease (COPD) induces an imbalance in T helper (Th) 17/regulatory T (Treg) cells that contributes to of the dysregulation of inflammation. Exercise training can modulate the immune response in healthy subjects.
Objective: We aimed to evaluate the effects of exercise training on Th17/Treg responses and the differentiation of Treg phenotypes in individuals with COPD.

Immune-mediated bone regeneration driven by bone biomaterials offers a therapeutic strategy for repairing bone defects. Among 2D nanomaterials, TiCT MXenes have garnered substantial attention for their potential in tissue regeneration. This investigation concentrates on the role of MXene nanocomposites in modulating the immune microenvironment within bone defects to facilitate bone tissue restoration.
