This study developed an immune molecule-based model to distinguish TSA from SSA using RNA sequencing data from the GEO datasets (GSE117606, GSE45270, GSE117607). Gene expression profiling was conducted with the R package GEOquery, and immune cell infiltration was assessed using CIBERSORTx. Differential expression analysis of immune-related genes was performed with the \"limma\" package. Enrichment analysis of differentially expressed genes (DEGs) was conducted using \"clusterProfiler\" for Gene Ontology and kyoto encyclopedia of genes and genomes pathways, identifying protein-protein interaction networks to find core hub genes. Notable differences in immune cell infiltration were observed among SSA, TSA, CRC, and healthy tissues, involving various immune cell types. A total of 45 DEGs (34 upregulated, 11 downregulated) were identified, with CCL2 and CXCL11 emerging as key hub genes. Their diagnostic potential was validated through receiver operating characteristic analysis in GEO datasets and clinical samples, while immunohistochemistry revealed decreased expression of CCL2 and CXCL11 in SSA compared to TSA and normal tissues, indicating their role in SSA pathogenesis and potential as molecular diagnostic markers. The diagnostic value of CCL2 is superior to that of CXCL11, while the diagnostic value of CXCL11 requires further experimental verification.</p>","PeriodicalId":19605,"journal":{"name":"Open Life Sciences","volume":"20 1","pages":"20251147"},"PeriodicalIF":1.7,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12355365/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144874386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective management of DFUs necessitates a comprehensive understanding of their risk factors and prognostic indicators. This review provides an in-depth examination of the various risk factors and prognostic markers associated with DFUs, integrating insights from cellular mechanisms, emerging biomarkers, omics-based research, serological studies, and clinical assessments. We explore the underlying biological processes, such as the impact of chronic hyperglycemia, oxidative stress, inflammation, impaired angiogenesis, and the role of the microbiome in DFU development. The role of serological markers, including inflammatory and glycemic indicators, in predicting DFU risk and progression is discussed. Additionally, clinical markers and advanced assessment tools, such as ulcer grading systems and imaging technologies, used to evaluate DFU severity and healing are reviewed. By synthesizing these diverse perspectives, this review aims to offer a holistic view of DFU management, highlighting how understanding the interplay of risk factors and prognostic markers can lead to improved prevention strategies and personalized therapeutic interventions.</p>","PeriodicalId":19605,"journal":{"name":"Open Life Sciences","volume":"20 1","pages":"20251137"},"PeriodicalIF":1.7,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12355360/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144874392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An SD model of humeral fracture in rats was established and treated. Following a 6-week treatment period, the morphology of the fracture was assessed. Serum interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), osteocalcin, C-telopeptide of type I collagen (CTX-I), and bone morphogenetic protein 2 (BMP-2) were determined. Alkaline phosphatase (ALP), receptor activator of nuclear factor-kappa B ligand (RANKL), osteoprotegerin (OPG), and other relevant molecules such as PI3K and p-AKT were measured. The results showed that SATB2 overexpression repaired humeral fracture and bone continuity. SATB2 overexpression resulted in a significant reduction in RANKL, IL-6, TNF-α, and CTX-I expression, while simultaneously increasing OPG, ALP, osteocalcin, and BMP-2. This indicates that SATB2 inhibits osteoclast activity and promotes osteoblast function. Additionally, SATB2 overexpression increased PI3K and p-AKT protein expression in humerus. Furthermore, the inhibitory effect of the PI3K/AKT inhibitor on PI3K and p-AKT protein expression was counterbalanced by upregulating SATB2.

Recently, new disease control methods based on phenological development, disease development, and meteorological data have been established in Türkiye. These models can provide sufficient protection with minimal fungicide use and minimize residue problems due to excessive fungicide use. In this study, the activities of the UC Davis risk index model, decision support strategy (DSS) models, and classical model, based on plant phenological development stages suggested by the Turkish Ministry of Agriculture and Forestry, were used to protect against powdery mildew. Three alternative control strategies were investigated for 2 years using two grape varieties. In addition, the amount of pesticide residue in the final product by the spraying models was also evaluated. The UC Davis risk index model was applicable in places with similar climatic conditions, such as Bursa Province, and showed better results than other spraying programs. Although the classical model proposed by the Ministry of Agriculture and Forestry is generally less effective than the UC Davis risk index model, once less spraying achieved high effectiveness rates each season. The UC Davis risk index model considerably lowered the disease incidence rate in clusters below the 5% limit. The DSS model provided poorer protection than the other two models evaluated in this study. Among the fungicides with active ingredients, thiophanate-methyl, kresoxim-methyl, and penconazole, only thiophanate-methyl exceeded the 0.1 ppm (mg/kg) limit specified in the European Union Pesticide Maximum Residue Limits and Turkish Food Codex Pesticide Maximum Residue Limits for both grape varieties.
