BACKGROUND The enzyme cellobiose dehydrogenase (CDH) can be used to oxidize lactose to lactobionic acid. As Sclerotium rolfsii is known to be a good producer of CDH, the aim of this paper was to simplify its production and secondly to systematically study its purification aiming for a high yield. Two preservation methods (freezing and freeze-drying) and the influence of several protectants were...

The purpose of this study was to develop freeze dried Polylactide-co-glycolide (PLGA) nanoparticles loaded with etoposide intended be administered intravenously improved therapeutic efficacy the drug and thereby reduced dose related toxicity associated it. were prepared using modified spontaneous emulsification solvent diffusion method (SESD).The in Vitro release (PLGA)–Nanoparticles NP carried...

This review provides a snapshot of the current state-of-the-art drying cells and spermatozoa. The major successes pitfalls most relevant literature are described separately for spermatozoa cells. Overall, data published so far indicate that we closer to success in spermatozoa, whereas situation is more complex with Critical presence xeroprotectants inside and, even so, protect subcellular compa...
