Nutraceutical formulation, characterisation, and in-vitro evaluation of methylselenocysteine and selenocystine using food derived chitosan:zein nanoparticles.

Food Res Int 2019 Jun 19;120:295-304. Epub 2019 Feb 19.

Environmental Science and Health Institute, Technological University Dublin, Grangegorman, Dublin 7, Ireland. Electronic address:

Selenoamino acids (SeAAs) have been shown to possess antioxidant and anticancer properties. However, their bioaccessibility is low and they may be toxic above the recommended nutritional intake level, thus improved targeted oral delivery methods are desirable. In this work, the SeAAs, Methylselenocysteine (MSC) and selenocystine (SeCys) were encapsulated into nanoparticles (NPs) using the mucoadhesive polymer chitosan (Cs), via ionotropic gelation with tripolyphosphate (TPP) and the NPs produced were then coated with zein (a maize derived prolamine rich protein).

Silica Coated Paclitaxel Nanocrystals Enable Neural Stem Cell Loading For Treatment of Ovarian Cancer.

Bioconjug Chem 2019 Apr 12. Epub 2019 Apr 12.

Ovarian cancer is commonly diagnosed only after it has metastasized to the abdominal cavity (stage III). While the current standard of care of intraperitoneal (IP) administration of cisplatin and paclitaxel (PTX) combination chemotherapy has benefit, patient 5-year survival rates are low and have not significantly improved in the past decade. The ability to target chemotherapy selectively to ovarian tumors while sparing normal tissue would improve efficacy and decrease toxicities. Read More
