Hyperglycemia and compromised beta-cell development were demonstrated in neonatal rats programmed with a gestational high-fat diet. The aim of this study was to determine whether these changes were attributed to impaired insulin release and altered immunoreactivity of Pdx-1, glucokinase (GK), and glucose transporter (GLUT)-2 in high-fat-programmed neonates.(More)
Three phases of perineurial development were recognised in the chicken sciatic nerve: (1) an early primitive phase during which the embryonic perineurium appeared to organise from the surrounding mesenchyme; (2) an intermediate phase of differentiation with the formation of a multilayered cellular network around the Schwann cell-axon complexes, and (3) a(More)
High-fat feeding reduces the expression of GLUT-2 and the glycolytic enzyme glucokinase (GK). The transcription factor, pancreatic duodenal homeobox-1 (Pdx-1), is important for beta-cell maintenance. The aim of the present study was to determine, in weanling Wistar rats, the effect of a maternal high-fat diet (HFD) during defined periods of gestation and(More)
In a retrospective study, scintigraphic spleen size was compared with actual spleen weight. Using the formula W = pi/7 h (h2 + 3ab), the normal weight was calculated too large and splenic enlargement was calculated too small. Other scintigraphic parameters seem to be just as unreliable. We suggest to judge scintigraphic spleen mass as normal and only be(More)
A clinical, radiological and biochemical study of 300 Cape coloured out-patients in order to clarify the diagnosis of rickets and to establish its incidence in the specific ethnic group selected, is presented. 95 Cases (31.6%) were diagnosed as suffering from rickets. Analysis of the results indicates that radiological examination is necessary to confirm or(More)
