Objective: Chronic nonbacterial osteomyelitis (CNO) is an autoinflammatory bone disorder. Its most severe form is referred to as chronic recurrent multifocal osteomyelitis (CRMO). Currently, the exact molecular pathophysiology of CNO/CRMO remains unknown. No uniform diagnostic standard and treatment protocol were available for this disease. The aim of this study was to identify the differentially expressed genes (DEGs) in CRMO tissues compared to normal control tissues to investigate the mechanisms of CRMO.
Materials: Microarray data from the GSE133378 (12 CRMO and 148 matched normal tissue samples) data sets were downloaded from the Gene Expression Omnibus (GEO) database. DEGs were identified using the limma package in the R software. Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and protein-protein interaction (PPI) network analysis were performed to further investigate the function of the identified DEGs.
Results: This study identified a total of 1299 differentially expressed mRNAs, including1177 upregulated genes and 122 downregulated genes, between CRMO and matched normal tissue samples. GO analyses showed that DEGs were enriched in immune-related terms. KEGG pathway enrichment analyses showed that the DEGs were mainly related to oxidative phosphorylation, ribosome, and Parkinson disease. Eight modules were extracted from the gene expression network, including one module constituted with immune-related genes and one module constituted with ribosomal-related genes.
Conclusion: Oxidative phosphorylation, ribosome, and Parkinson disease pathways were significantly associated with CRMO. The immune-related genes including IRF5, OAS3, and HLA-A, as well as numerous ribosomal-related genes, might be implicated in the pathogenesis of CRMO. The identification of these genes may contribute to the development of early diagnostic tools, prognostic markers, or therapeutic targets in CRMO.

Tumor surgery often leads to tumor residue, tissue defects, and drug-resistant bacterial infections, resulting in high recurrence rates and chronic wounds. In this study, an injectable hydrogel was synthesized using glycidyl trimethyl ammonium chloride-chitosan (GCh) and formylbenzoic acid-modified chrysomycin A (CA)-loaded F127 micelles (F127FA-CA). The formation of the hydrogel is achieved through Schiff base conjugation, which occurs between the amino groups present in GCh and the aldehyde groups located on the micelle surfaces.

Treatment-resistant depression (TRD) is a severe condition characterized by chronic and recurrent depressive symptoms, leading to significant morbidity and a considerable socio-economic impact. Genetic and biological studies suggest that TRD is associated with distinct biological characteristics. In this study, we analysed whole-transcriptome differences in 293 patients with major depressive disorder (MDD) to compare TRD (N = 150) vs non-TRD (N = 143) cases.

Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.
Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.

Immunoglobulin A nephropathy (IgAN), the most prevalent primary glomerulonephritis globally, is characterized by mesangial IgA deposition and heterogeneous clinical trajectories. Historically, management relied on renin-angiotensin system inhibition and empirical immunosuppression, yet high lifetime kidney failure risk persists despite optimized care. This review synthesizes advances in molecular pathogenesis, highlighting how the traditional multi-hit hypothesis-while foundational for targeted therapy development-fails to capture IgAN's recurrent, self-amplifying nature.

A 1-year-old intact Nigerian dwarf nulliparous doe was presented to the Auburn University College of Veterinary Medicine, Large Animal Teaching Hospital in March 2024 for evaluation of recurrent perivulvar masses of 3 mo duration. Transcutaneous ultrasonographic examination of the labia and ventrolateral peri-vulvar area was carried out. This examination revealed a horizontally oriented, bilobed mass on the dorsal left labia majora, and a separate mass located directly below the ventral vulvar commissure.
