Impact of galacto-oligosaccharides on the gut microbiota composition and metabolic activity upon antibiotic treatment during in vitro fermentation

Prebiotics are considered to have potential to reduce disturbances in the gut microbiota induced by antibiotics. Results in literature are, however, not consistent. The current in vitro study conducted in a fermentation screening platform allowed to unambiguously compare the impact of galacto-oligosaccharides (GOS) on adult gut microbiota...

A new approach to predict human intestinal absorption using porcine intestinal tissue and biorelevant matrices

A reliable prediction of the oral bioavailability in humans is crucial and of high interest for pharmaceutical and food industry. The predictive value of currently used in silico methods, in vitro cell lines, ex vivo intestinal tissue and/or in vivo animal studies for human intestinal absorption, however, is often insufficient, especially when...

The in vivo rat skin photomicronucleus assay: Phototoxicity and photogenotoxicity evaluation of six fluoroquinolones

An in vivo photomicronucleus test (MNT) using rat skin, the target organ for photoirritancy and carcinogenicity, was recently described. The assay was evaluated using fluoroquinolone (FQ) antibiotics with varying degrees of phototoxic potency (i.e. sparflocacin [SPFX], lomefloxacin [LOFX], ciprofloxacin [CIFX], levofloxacin [LEFX], gemifloxacin ...
