The animal gastrointestinal tract houses a large microbial community, the gut microbiota, that confers many benefits to its host, such as protection from pathogens and provision of essential metabolites. Metagenomic approaches have defined the chicken fecal microbiota in other studies, but here, we wished to assess the correlation between the metagenome and(More)
The plasma pharmacokinetic characteristics of the chemopreventive isothiocyanate sulforaphane were determined in six human volunteers following single and repeated intake of raw broccoli. Initially, an analytical method utilising LC-MS/MS, capable of determining low levels of sulforaphane in human plasma was developed and validated. The plasma profile of(More)
Sulforaphane is a naturally occurring isothiocyanate with promising chemopreventive activity. An analytical method, utilising liquid chromatography-MS/MS, which allows the determination of sulforaphane in small volumes of rat plasma following exposure to low dietary doses, was developed and validated, and employed to determine its absolute bioavailability(More)
New forms of transmissible spongiform encephalopathy (TSE) continue to be identified, and consequently sensitive differential diagnosis is increasingly important both for the management of disease in humans and livestock and in providing confidence in the safety of the food chain. TSE diseases are associated with accumulation of protease-resistant prion(More)
Prion diseases or transmissible spongiform encephalopathies (TSEs) in small ruminants are presented in many forms: classical scrapie, Nor98/atypical scrapie, CH1641 scrapie and bovine spongiform encephalopathy (BSE). We previously described a multiplex immunofluorometric assay (mIFMA), based on a bead array flow cytometry technology, which provided, in a(More)
The current batch potency test for Leptospira interrogans serovar Canicola vaccines requires the use of a large number of hamsters and has severe effects (i.e., hepatic and renal failure resulting in death); while this vaccine is effective, a safer, cheaper, more ethical replacement is desired. The aim of this study was to analyze vaccine proteomes and(More)
OBJECTIVES Mycoplasma mycoides subspecies capri is one of the causative agents of contagious agalactia in goats. The disease is characterised by mastitis, pneumonia, arthritis, keratitis and in acute cases septicaemia. No vaccine is currently available that has been demonstrated to prevent disease. METHODS This study used two-dimensional electrophoresis(More)
Prions are proteins that can exist in two (or more) folding states, a normal or cellular form and a series of infectious or prion forms, which are prone to aggregate. The prion form can induce conversion of the cellular form and so transmit phenotypic effects of this structural rearrangement within and between cells and organisms. The conversion of PrP(C),(More)
Protein misfolding, protein aggregation and disruption to cellular proteostasis are key processes in the propagation of disease and, in some progressive neurodegenerative diseases of the central nervous system, the misfolded protein can act as a self-replicating template or prion converting its normal isoform into a misfolded copy of itself. We have(More)
