Humans host an intestinal population of microbes--collectively referred to as the gut microbiome--which encode the carbohydrate active enzymes, or CAZymes, that are absent from the human genome. These CAZymes help to extract energy from recalcitrant polysaccharides. The question then arises as to if and how the microbiome adapts to new carbohydrate sources(More)
A well-balanced human diet includes a significant intake of non-starch polysaccharides, collectively termed 'dietary fibre', from the cell walls of diverse fruits and vegetables. Owing to the paucity of alimentary enzymes encoded by the human genome, our ability to derive energy from dietary fibre depends on the saccharification and fermentation of complex(More)
The critical importance of gastrointestinal microbes to digestion of dietary fiber in humans and other mammals has been appreciated for decades. Symbiotic microorganisms expand mammalian digestive physiology by providing an armament of diverse polysaccharide-degrading enzymes, which are largely absent in mammalian genomes. By out-sourcing this aspect of(More)
The purpose of this study was to investigate the utility of a combined GnRH-agonist (GnRH-a) and human chorionic gonadotropin (hCG) trigger in improving ICSI cycle outcomes in patients with poor fertilization history after standard hCG trigger in prior ICSI cycles. Retrospective cohort study. Patients with a fertilization rate of <20% in at least two prior(More)
