Journal ArticleDOI
Diets of savanna ungulates from stable carbon isotope composition of faeces
Daryl Codron,Jacqui Codron,Julia A. Lee-Thorp,Julia A. Lee-Thorp,Matt Sponheimer,Darryl J. de Ruiter,Judith Sealy,Rina Grant,Nicolaas H. Fourie +8 more
TL;DR: Cluster analysis based on a data matrix that incorporates the extent of spatio-temporal dietary variation among Kruger Park ungulates reveals several distinct categories of feeding preferences that extend beyond a two-edged browser/grazer dichotomy, such as mixed-feeders with a preference for either forage class, and spatial/seasonal shifts between uniform and mixed-feeding styles among variable browsers.
Journal ArticleDOI
Elevated circulating miR-150 and miR-342-3p in patients with irritable bowel syndrome.
Nicolaas H. Fourie,Ralph M. Peace,Sarah K. Abey,LeeAnne B. Sherwin,Bridgett Rahim-Williams,Paul A. Smyser,John W. Wiley,Wendy A. Henderson +7 more
TL;DR: This preliminary study reports the association of two miRNAs, detected in whole blood, with IBS, which link to pain and inflammatory pathways both of which are thought to be dysregulated in IBS.
Journal ArticleDOI
Hair cortisol levels track phylogenetic and age related differences in hypothalamic-pituitary-adrenal (HPA) axis activity in non-human primates.
TL;DR: Results suggest that hair may be an ideal hormone bearing substrate for research focused on the examination of population endocrine profiles, cross-sectional studies of endocrine function and taxon variation in hormone levels, as well as stable behavioral trends.
Journal ArticleDOI
Biogeochemical and craniometric investigation of dietary ecology, niche separation, and taxonomy of Plio-Pleistocene cercopithecoids from the Makapansgat Limeworks.
Nicolaas H. Fourie,Nicolaas H. Fourie,Julia A. Lee-Thorp,Julia A. Lee-Thorp,Rebecca Rogers Ackermann +4 more
TL;DR: Although biogeochemical dietary indicators point towards distinct dietary ecologies within and between fossil genera at Makapansgat, within the genus Parapapio disjunctions exist between the dietary categories and the taxonomic assignment of specimens.
Journal ArticleDOI
Gastrointestinal permeability in patients with irritable bowel syndrome assessed using a four probe permeability solution
Arseima Y. Del Valle-Pinero,Hendrick E. Van Deventer,Nicolaas H. Fourie,Angela C. Martino,Nayan Patel,Alan T. Remaley,Wendy A. Henderson +6 more
TL;DR: The study demonstrates the clinical potential of this non-invasive method for assessing alterations in gastrointestinal permeability in patients with IBS and healthy controls.
