Autophagy Attenuates Oxidative Stress-Induced Collagen Degradation in Vaginal Fibroblasts: Implications for Pelvic Organ Prolapse.
Int Urogynecol J
January 2025
Department of Obstetrics and Gynecology, The Third Affiliated Hospital of Guangzhou Medical University, Guangzhou, 510150, China.
Introduction And Hypothesis: The relationship between autophagy and pelvic organ prolapse (POP) remains unknown. The aim of this novel experimental study, utilizing tissue samples derived from women undergoing gynecological surgery, is to investigate the role of autophagy in mitigating collagen degradation in human vaginal fibroblasts induced by oxidative stress, with particular emphasis on its implications in the pathogenesis of POP. Exploring the role of autophagy in protecting against collagen degradation and cellular senescence in human vaginal fibroblasts under oxidative stress may offer new insights into therapeutic strategies for conditions such as POP.

Department of Radiotherapy, Changzhou Cancer Hospital, Honghe Road, Xinbei Area, Changzhou, 213032, China.
Purpose: Conventional radiotherapy (CRT) has limited local control and poses a high risk of severe toxicity in large lung tumors. This study aimed to develop an integrated treatment plan that combines CRT with lattice boost radiotherapy (LRT) and monitors its dosimetric characteristics.
Methods: This study employed cone-beam computed tomography from 115 lung cancer patients to develop a U-Net + + deep learning model for generating synthetic CT (sCT).
Cardiac allograft tolerance can be achieved in nonhuman primates by donor bone marrow and kidney cotransplantation.

Long-term, immunosuppression-free allograft survival has been induced in human and nonhuman primate (NHP) kidney recipients after nonmyeloablative conditioning and donor bone marrow transplantation (DBMT), resulting in transient mixed hematopoietic chimerism. However, the same strategy has consistently failed in NHP heart transplant recipients. Here, we investigated whether long-term heart allograft survival could be achieved by cotransplanting kidneys from the same donor.

Background: Atypical teratoid/rhabdoid tumours (ATRTs) are malignant central nervous system tumours, typically presenting in the posterior fossa of very young children. Prognosis remains poor despite current therapy, while tumorigenesis implicates both genomic and epigenetic dysregulation. Primary diffuse leptomeningeal (PDL) ATRT, characterised by the absence of an intraparenchymal mass lesion, is seldom reported but appears associated with a dismal outcome.

Cancer immunotherapy has revolutionized cancer treatment by harnessing the body's immune system to recognize and attack tumors. Over the past 25 years, the use of blocking antibodies has fundamentally transformed the landscape of cancer therapy. However, despite extensive research, agonist antibodies targeting costimulatory receptors such as ICOS, GITR, OX40, CD27, and 4-1BB have consistently underperformed in clinical trials over the past 15 years, failing to meet the anticipated success.
