Platelet‐rich plasma (PRP) has grown as an attractive biologic instrument in regenerative medicine for its powerful healing properties. It is considered a source of growth factors that may induce tissue repairing and improve fibrosis. This product proven efficacy multiple studies, but effect on cisplatin‐induced nephrotoxicity not yet been elucidated. The present investigation was performed to estimate the protective impact platelet‐rich against cisplatin‐ (CP‐) evoked male rats....

Ovarian cancer is a leading cause of death due to the fact that most patients are diagnosed at an advanced stage(s) disease progression because it cannot be detected early stage. An immunogenic tumor and immunotherapy strongly pursued through targeting immune checkpoints. In previous study, signaling pathways their components have been shown as key factor for initiation, progression, finally scope diagnosis. Thus, in ovarian immune-based prognostic signature remains potential can explored...

Glioblastoma multiforme (GBM) is regarded as the most aggressive form of brain tumor delineated by high cellular heterogeneity; it resistant to conventional therapeutic regimens. In this study, anti-cancer potential garcinol, a naturally derived benzophenone, was assessed against GBM. During analysis, we observed reduction in viability rat glioblastoma C6 cells at concentration 30 µM extract (p < 0.001). Exposure garcinol also induced nuclear fragmentation and condensation, evidenced...
