The potential biodegradation of crude oil was assessed based on the development of a fermentative process with a strain of Pseudomonas aeruginosa which produced 15.4 g/L rhamnolipids when cultured in a basal mineral medium using glycerol as a sole carbon source. However, neither cell growth nor rhamnolipid production was observed in the comparative culture(More)
This paper presents a review of recent research on the hypothermic storage of hepatocytes. The first focus is on the diversity of methodologies currently employed in this area. The cell damage caused by hypothermic preservation and its possible mechanism are then investigated on both morphological and molecular biology. Later, the gene expressions on a mRNA(More)
Mechanism-based inactivation (MBI) of cytochrome P450 (CYP) 3A by verapamil and the resulting drug-drug interactions have been studied in vitro, but the inhibition of verapamil on its own metabolic clearance in clinic, namely auto-inhibition of verapamil metabolism, has never been reproduced in vitro. This paper aimed to evaluate the utility of gel(More)
GO microcapsules were assembled on the surface of atomized droplets prepared by a spray-drying strategy. The nanochannels in the microcapsule wall can be adjusted by water-soluble polymers and make the microcapsule exhibit sustained release. The strategy can further be employed to encapsulate metal organic frameworks to obtain MOF-GO yolk-shell(More)
Herbal medicines are gradually being accepted for their low toxicity and high efficacy, but their hepatotoxicity still needs to be recognized. For the multiple compounds in herbs, hepatocytes in vitro would be a useful tool for the evaluation of herbal hepatotoxicity. This study aimed at cocklebur/atractyloside-induced hepatotoxicity and the protective(More)
Biosurfactant rhamnolipids have been claimed to show biological activities of inhibiting the proliferation of cancer cells. In this study, the cytotoxicity of rhamnolipids was examined on four cancer cells (HepG2, Caco-2, Hela, MCF-7 cells) and two normal cells (HK-2 cell, primary hepatocyte). Interestingly, both cancer cells and normal cells exhibited(More)
Troglitazone, despite passing preclinical trials on animals, was shortly withdrawn from market due to its severe hepatotoxicity in clinic. As rat hepatocyte monolayer consistently showed sensitive troglitazone toxicity as human hepatocyte monolayer in contrast to the species-specific toxicity in vivo, this paper utilized both hepatocytes in(More)
Collagen gel-based 3D cultures of hepatocytes have been proposed for evaluation of drug hepatotoxicity because of their more reliability than traditional monolayer culture. The collagen gel entrapment of hepatocytes in hollow fibers has been proven to well reflect the drug hepatotoxicity in vivo but was limited by adsorption of hydrophobic drugs onto hollow(More)
A non-activation (NA) ZnO array is directly grown on a PVDF hollow fiber membrane. The defect-free MOF layers can be synthesized easily on the NA-ZnO array without any activation procedure. The array and MOF layers are strongly adhered to the hollow fiber membrane. The prepared ZIF membranes exhibit excellent gas separation performances.
Herein we report a new ammoniation-based chemical modification strategy for synthesis of continuous and uniform metal-organic framework (MOF)/polyvinylidene fluoride (PVDF) membranes with attractive performance. Ammoniation can promote the support PVDF membrane to produce amino groups, form a nanoparticle structure, and be well cross-linked; therefore, the(More)
