Background: Despite advancements in laboratory animal facility management, pinworm infections remain a persistent issue in immunodeficient mouse colonies. Rapid diagnosis and treatment are crucial to mitigating potential scientific and economic consequences. Effective control requires both the administration of anthelmintic agents and rigorous environmental decontamination. However, the safety and efficacy of these treatments in genetically modified mouse models remains uncertain.Case presentation Aspiculuris tetraptera infestation was identified in multiple immunodeficient mouse models housed in a laboratory facility. Diagnosis was confirmed through fecal flotation for egg detection and necropsy for adult worm examination in the large intestines. Mice received three subcutaneous ivermectin injections at two-week intervals, coupled with environmental decontamination using ivermectin spray for four consecutive weeks. Following treatment, all colonies tested negative for A. tetraptera without any mortality. Conclusions A combination of subcutaneous ivermectin injection and environmental spray application effectively eradicated A. tetraptera infestation in immunodeficient mouse colonies. The treatment protocol led to the complete elimination of eggs and adult worms, offering a practical strategy for managing pinworm infections in genetically modified mouse models. Limitations include the small sample size, and the lack of a comprehensive evaluation of physiological and metabolic safety in immunodeficient mice. Further validation will be required to confirm the broader applicability of this approach.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a global health issue due to its increasing prevalence associated with lifestyle changes and its strong correlation with metabolic syndrome. Farnesoid X receptor (FXR) is a nuclear receptor that plays a pivotal role in regulating bile acid, lipid, and glucose metabolism, making it an attractive therapeutic target for liver and metabolic diseases. In this study, we investigated the effects of MHY5456, a synthetic agonist of FXR, on hepatic metabolism and fibrosis. MHY5456 enhanced the transcriptional activity of FXR in a concentration-dependent manner.Treatment of AC2F rat liver-derived cells with MHY5456 resulted in the downregulation of genes involved in lipid accumulation and an upregulation of mitochondrial-related gene expression. Additionally, MHY5456 significantly reduced oleic acid (OA)-induced lipid accumulation. To assess its anti-fibrotic potential, we tested its effects on transforming growth factor-beta (TGF-β)-induced fibrosis in LX2 human hepatic stellate cells (HSCs). MHY5456 significantly suppressed the expression of fibrosis-related genes and proteins. In vivo, administration of MHY5456 to mice fed a methionine-choline-deficient (MCD) diet alleviated hepatic fibrosis, inflammation, and lipid accumulation. These results show that FXR activation by MHY5456 modulates lipid metabolism and fibrotic pathways, suggesting its potential as a pharmacological candidate for liver and metabolic disorders, including MASLD. Further pharmacological and toxicological studies are needed to confirm its therapeutic relevance.

Purpose: Total hip arthroplasty (THA) is performed using various approaches, including posterior, lateral, and direct anterior approaches.The most beneficial method is controversial. Each approach has its advantages and disadvantages. This study compared patient satisfaction after bilateral THA using the direct anterior and lateral approaches on the same patient, considering the advantages and disadvantages of each approach. Materials and Methods: This study examined 30 patients who underwent bilateral THA: two with femoral neck fractures, 18 with osteonecrosis of the femoral head, six with borderline dysplasia-induced hip osteoarthritis, and four with degenerative hip osteoarthritis.Without distinguishing between the left and right sides, THA was performed randomly using the direct anterior approach on one side and the lateral approach on the other. The results of THA were compared using different approaches on the same patient, and patient satisfaction was evaluated. Results: Surgery using the direct anterior approach for THA showed favorable results in terms of the initial postoperative pain compared to surgery using the lateral approach. On the other hand, there was no significant difference observed after one month post-surgery. Among the participants, three preferred the direct anterior approach; four preferred the lateral approach, and 23 reported no preference. Conclusion In THA, the direct anterior approach may offer advantages in terms of initial postoperative pain and rehabilitation compared to the lateral approach. Nevertheless, the pain and joint function one month after surgery were similar between the two approaches.Therefore, the choice of approach should be determined by the surgeon's preference or experience, as both methods appear rational.

The role of acetylated apurinic/apyrimidinic endonuclease 1/redox factor 1 (APE1/Ref-1) in ovarian cancer remains poorly understood. Therefore, this study aimed to investigate the combined effect of recombinant human APE1/Ref-1 (rhAPE1/Ref-1) and aspirin (ASA) on two ovarian cancer cells, PEO-14, and CAOV3.The viability and apoptosis of ovarian cancer cells treated with rhAPE1/Ref-1 or ASA were assessed. Our results demonstrated that ASA induced rhAPE1/Ref-1 acetylation and widespread hyperacetylation in PEO-14 cells. Additionally, co-treatment with rhAPE1/Ref-1 and ASA substantially reduced cell viability and induced PEO-14 cell apoptosis, not CAOV3, in a dose-dependent manner. ASA increased the expression and membrane localization of the receptor for advanced glycation endproducts (RAGEs). Acetylated APE1/Ref-1 showed enhanced binding to RAGEs. In contrast, RAGE knockdown reduced cell death and poly(ADP-ribose) polymerase cleavage caused by rhAPE1/Ref-1 and ASA combination treatment, highlighting the importance of the APE1/Ref-1-RAGE interaction in triggering apoptosis. Moreover, combination treatment with rhAPE1/Ref-1 and ASA effectively induced apoptosis in 3D spheroid cultures of PEO-14 cells, a model that better mimics the tumor microenvironment. These results demonstrate that acetylated APE1/Ref-1 and its interaction with RAGE is a potential therapeutic target for ovarian cancer. Thus, the combination of ASA and APE1/Ref-1 may offer a promising new strategy for inducing cancer cell death.
