short-term probiotic therapy alleviates small intestinal bacterial overgrowth, but does not improve intestinal permeability in chronic liver disease.	: although numerous animal studies suggest that probiotic therapy has beneficial effects in various liver diseases, the evidence for beneficial effects in human liver disease is controversial. this study was carried out to investigate the efficacy of probiotic therapy in alleviating small intestinal bacterial overgrowth (sibo) and permeability in chronic liver disease.	2014	25244414
the brain-gut axis: a target for treating stress-related disorders.	the brain-gut axis provides a bidirectional means of communication between the microbiota within the gut and the brain. stress acting via the brain can result in alteration of the microbial composition of the gut, but increasing evidence indicates that bacteria within the gut can influence brain neurochemistry and behaviour. it is clear that post-natal colonisation of the gut plays a key role in regulating the development of the hypothalamic-pituitary-adrenal axis and the development of pivotal ...	2013	25224893
tolerability of a probiotic in subjects with a history of methicillin-resistant staphylococcus aureus colonisation.	methicillin-resistant staphylococcus aureus (mrsa) is a pathogen of major public health importance. colonisation precedes infection; thus reducing mrsa carriage may be of benefit for reducing infection. probiotics represent a novel approach to reducing mrsa carriage. we undertook a pilot feasibility randomised controlled trial of the tolerability and acceptability of probiotics for reducing nasal and intestinal carriage of mrsa. in addition, subjects were screened for vancomycin-resistant entero ...	2014	25213147
endogenous biotin-binding proteins: an overlooked factor causing false positives in streptavidin-based protein detection.	biotinylation is widely used in dna, rna and protein probing assays as this molecule has generally no impact on the biological activity of its substrate. during the streptavidin-based detection of glycoproteins in lactobacillus rhamnosus gg with biotinylated lectin probes, a strong positive band of approximately 125 kda was observed, present in different cellular fractions. this potential glycoprotein reacted heavily with concanavalin a (cona), a lectin that specifically binds glucose and mannos ...	2015	25211245
