In vitro Antidiabetic and Antioxidant effects of different extracts of Catharanthus roseus and its indole alkaloid, vindoline
(MPDI, 2020)The Catharanthus roseus plant has been used traditionally to treat diabetes mellitus. Scientific evidence supporting the antidiabetic effects of this plant’s active ingredient-vindoline has not been fully evaluated. In ... -
The In vitro biological activity of biosynthesized silver nanoparticles produced using mangifera indica stem bark extract and properties of Its pharmaceutical gel formulation
(Springer, 2023)This study reports the production of silver nanoparticles using Mangifera indica stem bark (aqueous and methanol) extracts as capping agents and formulation of pharmaceutical gel loaded with the nanoparticles. The extracts ... -
In vitro comparison of the anti-proliferative effects of galenia africana on human skin cell lines
(MDPI, 2021)Malignant melanoma is the major cause of skin cancer-related deaths. Surgery in combina-tion with radiotherapy, immunotherapy or chemotherapy is used to eradicate cancer cells, however, this treatment option is limited by ... -
In vitro corrosion of titanium nitride and oxynitride-based biocompatible coatings deposited on stainless steel
(MPDI, 2020)The reactive cathodic arc deposition technique was used to produce Ti nitride and oxynitride coatings on 304 stainless steel substrates (SS). Both mono (SS/TiN, SS/TiNO) and bilayer coatings (SS/TiN/TiNO and SS/TiNO/TiN) ... -
In vitro effects of aqueous extract of unfermented rooibos on human spermatozoa
(Wiley, 2022)The inability to conceive is a baleful experience for thousands of couples worldwide. Among different well-known reproductive techniques, medicinal plants have been utilized to treat male infertility. Medicinal plants, ... -
The in vitro effects of artificial and natural sweeteners on the immune system using whole blood culture assays
(Taylor & Francis, 2013)This article investigates the effects of commercially available artificial (aspartame, saccharin, sucralose) and natural sweeteners (brown sugar, white sugar, molasses) on the immune system. Human whole blood cultures ... -
