Tumor-derived lactic acid promotes acetylation of histone H3K27 and differentiation of IL-10-producing regulatory B cells through direct and indirect signaling pathways.

Tumor cells are known to enhance glycolysis, even under normoxic conditions, via the Warburg effect, producing excess lactic acid in the tumor microenvironment. Lactic acid enhances the IL-23/IL-17 pathway and induces chronic inflammation. The acidic microenvironment formed by lactic acid suppresses immune cell proliferation and activation.

Treatment strategies for revision surgery of artificial urinary sphincter: A review.

Artificial urinary sphincters (AUS) are an effective treatment for male stress urinary incontinence (SUI). However, infection, erosion, mechanical failure, atrophy, and balloon deterioration cause device malfunction in approximately half of patients by 10 years after implantation. Many patients desire to regain urinary continence and require revision surgery (RS), including device removal and simultaneous or delayed implantation.

[Preoperative Virtual Reality Simulation Regarding the Appropriate Port Location for Thoracoscopic Surgery for the Mediastinal or Chest Wall Lesions].

In thoracoscopic surgery for mediastinal or chest wall lesions the suitable position of ports( trocars) are required depending on the position of a target lesion in a particular patient. We have therefore developed a virtual reality (VR) simulation system using the specific data of each individual patient. The model data generation system, PASS-GEN, is customized for thoracic surgery.
