Scabies is an invasive skin condition caused by Sarcoptes scabiei mites. The present study investigates the antiscabies potential of coconut seed extract (CSE) in rabbits. GC-MS analysis oil identified 17 known compounds, while CSE phytochemical investigation afforded 4 ones. topical application improved all signs infection, and improvement started 3 days post application. However, vitro 99% mortality mites 1 day Histopathological examination revealed absence inflammatory infiltration...

Impaired skin wound healing is still a major challenge, especially with immunocompromised patients who express delayed and are susceptible to infections. Injection of rat-derived bone marrow mesenchymal stem cells (BMMSCs) via the tail vein accelerates cutaneous their paracrine activity. The present work aimed investigate combined wound-healing potential BMMSCs Halimeda macroloba algae extract in rats. High-resolution liquid chromatography-mass spectrometry (HR-LC-MS) investigation revealed...

The current study investigated the scabicidal potential of Egyptian mandarin peel oil (Citrus reticulata Blanco, F. Rutaceae) against sarcoptic mange-in-rabbits. Analysis oil's GC-MS identified a total 20 compounds, accounting for 98.91% all compounds found. Mandarin topical application improved signs infection, causing effect three days later, whereas in vitro caused complete mite mortality one day later. In comparison to ivermectin, histopathological analysis showed that epidermis'...

Delayed healing of chronic wounds results in amputation and mortality rates serious cases. The present study examines the merged wound-restorative efficacy injectable bone marrow-derived mesenchymal stem cells (BMMSCs) topical Callyspongia sp. extract immunocompromised rats. HR-LC-MS analysis tentatively identified twenty-nine compounds (1-29) highlighted its richness fatty acids terpenoids, known for their wound regenerating efficacies. closure was greatly prominent BMMSCs/Callyspongia...

Metabolic profiling of the ethyl acetate extract Corchorus olitorius seeds associated with Penicillium sp. resulted in dereplication sixteen compounds (1–16). The present work investigated combined wound-healing potential BMMSCs and immunocompromised rats. BMMSCs/Penicillium combination could attenuate oxidative stress, pro-inflammatory cytokines, NF-KB activation, at day 16. Network pharmacology identified ten key genes connected to process: AKT1, TNF, STAT3, TP53, IL1B, MMP9, CASP3, PTGS2,...
