This study was performed to elucidate the protection afforded by post-treatment with Betoptic (0.25% betaxolol) against neuronal cell damage after ischemia/reperfusion insult in rats. Betaxolol was applied topically after the start of reperfusion and its effect was evaluated by morphometry and choline acetyltransferase immunoreactivity of retinas at 7 days after reperfusion. In non-treated eyes, the thickness of the inner plexiform layer decreased markedly after a reperfusion period of both 3 and 7 days. However, when eyes were treated with betaxolol after ischemia/reperfusion injury, both the reduction of the inner plexiform layer thickness and the retinal choline acetyltransferase immunoreactivity were significantly attenuated. These findings suggest that betaxolol is an efficient neuroprotective agent and prevents the retinal cell damage induced by ischemic injury in rats.

Anaphase-promoting complex/cyclosome (APC/C) regulates the cell cycle by destruction of target proteins ubiquitination. However, understanding the control of APC/C has remained elusive. We identify APC2, the catalytic core subunit of APC/C, as a binding partner of active regulator of SIRT1 (AROS).

Objective: Traumatic brain injury (TBI), a prevalent neurological disorder worldwide, is marked by varying degrees of neurological dysfunction. A key contributor to secondary damage and impediments in the repair process is the unregulated activation of microglia, which triggers neuroinflammation. Emerging evidence highlights the therapeutic potential of transcranial pulsed current stimulation (tPCS) in mitigating neurological deficits.

Objectives: To investigate the effect of (HP) on bleomycin (BLM)-induced pulmonary fibrosis in mice and on TGF-β1-induced human fetal lung fibroblasts (HFL1).
Methods: Thirty male C57BL/6 mice were randomly divided into control group, BLM-induced pulmonary fibrosis model group, low- and high-dose HP treatment groups (3 and 21 mg/kg, respectively), and 300 mg/kg pirfenidone (positive control) group. The effects of drug treatment for 21 days were assessed by examining respiratory function, lung histopathology, and expression of fibrosis markers in the lung tissues of the mouse models.

Objectives: To investigate the mechanism of (QJZ) for ameliorating renal damage in MRL/lpr mice.
Methods: With 6 female C57BL/6 mice as the normal control group, 30 female MRL/lpr mice were randomized into model group, QJZ treatment groups at low, moderate and high doses, and prednisone treatment group (6). After 8 weeks of treatment, the mice were examined for 24-h urine protein, creatinine and albumin levels, serum levels of IgG, complement 3 (C3), C4, anti-dsDNA, interferon γ (IFN‑γ) and interleukin 17 (IL-17).

Objectives: In this study, we explored the mechanism by which DDIT4 influences the polarization phenotypic transformation of macrophages and inflammation through the regulation of mTOR signaling pathway, providing a new mechanism and target for the treatment of diabetic nephropathy.
Methods: The degree of inflammation and injury in renal tissues of diabetic kidney disease (DKD) animal model was evaluated using biochemical assays, renal pathology examinations, and Western blot tests. Podocytes and macrophages were isolated from renal tissues to observe the extent of podocyte injury and the quantity and polarization phenotype of macrophage infiltration.
