Intervertebral disc degeneration (IVDD) is a leading cause of low back pain, primarily driven by inflammatory processes within the disc, particularly involving the infiltration and activity of macrophages. High Mobility Group Box 1 (HMGB1) has been identified as a crucial mediator in this inflammatory cascade, yet its precise role in macrophage-induced disc degeneration remains unclear. In this study, we employed a combination of in vivo and in vitro models, including genetically engineered mice with macrophage-specific overexpression of HMGB1, a rat model of IVDD, and cultured macrophages and nucleus pulposus cells (NPCs), to elucidate the role of HMGB1 in IVDD.

Background: Liver injury manifesting as hepatic enzyme abnormalities, has been occasionally identified to be a feature of primary or secondary Addison's disease, an uncommon endocrine disease characterized by adrenal insufficiency. There have been no more than 30 reported cases of liver injury explicitly attributed to Addison's disease. Liver injury resulting from adrenal insufficiency due to glucocorticoid withdrawal is exceptionally rarer.

Introduction: Bacterial infection, a complex wound microenvironment, and a persistent inflammatory response in acute wounds can result in delayed healing and abnormal scar formation, thereby compromising the normal function and aesthetic appearance of skin tissue. This issue represents one of the most challenging problems in clinical practice. This study aims to develop a hydrogel dressing specifically designed for the treatment of acute wounds, providing immediate and effective protection for the affected areas.

Colorectal cancer is a lethal malignancy that begins from acquired/inherent premalignant lesions. Thus, targeting these lesions at an early stage of the disease could impede the oncogenesis and maximize the efficacy. The present work underscores a combinatorial therapy of paclitaxel (PTX) and glycyrrhizin (GL) delivered via gelatin-derived core-shell nanoparticles [AC-PCL(GL + PTX)-GNPs] for effective management of precancerous lesions.
