Background: Multidrug resistance (MDR) is known to defeat most chemotherapies as one of the main anticancer strategies. The role of overexpression/overactivation of ABC transporters, especially P-glycoprotein (P-gp), in the development of chemotherapy has long been demonstrated. Salinispora is a marine actinomycete genus known for the production of novel bioactive metabolites. Methods: In this...

Microbial steroid biotransformation have found wide-reaching application for the production of more precious and functionalized compounds due to their high regio-and stereoselectivity. In this study, the possibility of using filamentous fungi Aspergillus brasiliensis cells in the biotransformation of progesterone (I), a C-21 steroid hormone was studied for the first time.The fungal strain was i...

Pharmacology and toxicology share a common interest in pharmacokinetic data, especially as it is available in pediatric populations. These data have been critical to the clinical pharmacologist for many years in designing age-specific dosing regimens. Now they are being used increasingly by toxicologists to understand the ontogeny of physiologic parameters that may affect the metabolism and cle...

become useful as a provocative and predictive test for early renal abnormalities. In summary, our data indicate that exercise microalbuminuria is not detected in most kidney donors and support the notion that the uninephrectomized state does not result in a progressive hyperfiltration nephropathy. In addition, longitudinal studies could reveal whether. a particular subset of donors with abnorma...

In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...
