Assessment of wound healing activity in diabetic mice treated with a novel therapeutic combination of selenium nanoparticles and platelets rich plasma.

Diabetic wound healing is sluggish, often ending in amputations. This study tested a novel, two-punch therapy in mice-Selenium nanoparticles (Se NPs) and platelet-rich plasma (PRP)-to boost healing. First, a mouse model of diabetes was created.

A promising protected ascorbic acid-hydroxyapatite nanocomposite as a skin anti-ager: A detailed photo-and thermal stability study.

A new ascorbic acid (AA) nanocomposite with low toxicity and high photo and thermal stability is constructed for certain dermatological applications in humans. The presented nanocomposite consists of AA, nano-hydroxyapatite (nHAp) and carboxymethyl cellulose (CMC). The physicochemical properties of such CMC-nHAp-AA nanocomposite were characterized using X-Ray diffractometery (XRD), Fourier Transform Infra-Red (FTIR), Energy Dispersive X-ray (EDX) and UV-VIS spectroscopies.
