In vitro wound healing and cytotoxic effects of sinigrin-phytosome complex
(Elsevier, 2016)Sinigrin is a class of glucosinolates found naturally in plants of the Brassicaceae family. Lately, studies have shown that sinigrin possesses anticancer, antibacterial and anti-inflammatory activities. Since its efficacy ... -
In vivo efficacy and bioavailability of lumefantrine: evaluating the application of Pheroid technology
(Elsevier, 2015)The oral absorption of compounds with low aqueous solubility, such as lumefantrine, is typically limited by the dissolution rate in the gastro-intestinal tract, resulting in erratic absorption and highly variable ... -
In vivo evaluation of acute intravenous toxicity of a [Ga-68]Ga-PSMA-11-microemulsion
(Elsevier, 2020)Microemulsions (MEs) are reported to improve the efficacy of a drug, minimise side effects and toxicity of the encapsulated compound. MEs are hypothesized to aid in making the encapsulated compound, which has been incorporated ... -
In vivo evaluation of the biodistribution and safety of PLGA nanoparticles as drug delivery systems
(Elsevier, 2010)The remarkable physicochemical properties of particles in the nanometer range have been proven to address many challenges in the field of science. However, the possible toxic effects of these particles have raised some ... -
