Perforator flap transplantation is an important technique in reconstructive surgery, but necrosis limits its clinical effectiveness. Thymoquinone (TQ), a natural bioactive plant quinone found black seed, exhibits anti-inflammatory, angiogenic, and antimicrobial properties. This study investigates the therapeutic effects of TQ perforator model through vivo vitro experiments. Human umbilical vein endothelial cells (HUVECs) were treated with Tert-butyl Hydroperoxide (TBHP) to simulate then TQ. In experiments used rat model, vascularization was assessed using Doppler ultrasound on days 3 7 after creation. On day post-surgery, samples collected evaluate vascularity, reactive oxygen species, apoptosis pyroptosis. Network pharmacology analysis conducted identify relevant signaling pathways, molecular docking techniques predict potential target binding sites. results showed that both treatment NLRP3 inhibitors reduced expression pyroptosis-related proteins. indicated TQ-treated group had increased survival area, blood flow intensity, microvascular density, while oxidative stress, apoptosis, pyroptosis levels reduced. Angiogenesis enhanced, SIRT1 protein increased, p-P65/NF-κB/NLRP3 pathway downregulated. After inhibitor, rate angiogenesis These findings suggest improves by inhibiting NF-κB/NLRP3 promoting angiogenesis.

Ischemic stroke (IS) represents a harmful neurological disorder with limited treatment options. Ferroptosis accounts for the iron-dependent, nonapoptotic cell death pattern, which shows feature of fatal lipid ROS accumulation. Nonetheless, ferroptosis-related biomarkers identifying IS early are currently lacking. The present study focused on investigating possible and analyzing their effects immune infiltration. Altogether five hub differentially expressed genes (DEFRGs) were identified from relevant databases. Additionally, single-cell RNA-sequencing (seq) analysis was conducted comprehensive mapping populations based database. These DEFRGs analyzed using gene set enrichment analysis, miRNA prediction, RNA-seq analysis. A transient middle cerebral artery occlusion mouse model constructed. We also adopted bioinformatics methods combined western blot, changes to mitochondria, hematoxylin & eosin staining, Nissl fluorescence immunohistochemistry, quantitative real-time polymerase chain reaction (qRT-PCR) show involvement ferroptosis in progression. results revealed that nuclear factor erythroid-derived 2-like 2 (Nfe2l2) potential candidate biomarker diagnosis, may be suppressed via Nfe2l2/HO-1 pathway. Thus, drug targeting Nfe2l2 can shed novel lights treatment.

Ischemic stroke, the most prevalent form of is responsible for highest disability rates globally and ranks as primary cause mortality worldwide. Sirt1, extensively investigated in neurodegenerative disorders, well-known earliest member sirtuins family. However, its mechanism action during ischemic stroke remains ambiguous. The literature examination revealed intricate involvement Sirt1 regulating both physiological pathological mechanisms stroke. demonstrates deacetylation effects on PGC-1α, HMGB1, FOXOs, p53. It hinders activation NLRP3 inflammasome NF-κB while also engaging with AMPK. regulates inflammatory response, oxidative stress, mitochondrial dysfunction, autophagy, pro-death, necrotic apoptosis. Therefore, potential a therapeutic target management promising.
