The relationship between the Stiles–Crawford effect of the first kind (SCE-I) and myopia

The Stiles-Crawford effect of the first kind (SCE-I) was measured on both emmetropic and myopic subjects at six different retinal locations. The results revealed a number of significant discrepancies in receptor alignment between the groups of different refractive errors. In myopic subjects, the receptors in the nasal retina (i.e. between the fovea and the optic nerve head) were found to be aligned nasally towards the optic nerve head, whereas the receptors in the temporal retina were aligned towards the centre of the exit pupil. In emmetropic subjects, the receptors across the retina were finely tuned towards the centre of the exit pupil. The magnitude of the receptor displacement in myopic subjects was found to be directly associated with the length of the eyeball.

Polymorphism analysis of four canine MHC class I genes

Abstract: We have studied the variability of four structurally complete dog leukocyte antigen (DLA) class I genes, termed DLA-12, -88, -79 and -64, in a population of mixed breed, unrelated dogs. The human HLA and canine DLA loci share a high degree of similarity in terms of gene structure. This analysis focused on the first three exons of each of four complete canine genes. Exons two and three are the major source of polymorphism in the corresponding human genes. In this analysis, DLA-88 was found to be significantly more polymorphic than the other three genes, with 44 distinct alleles observed among 63 mixed breed, unrelated dogs. The remaining genes had between one and four alleles when examined in 25 dogs. This work was carried out as part of an effort to develop an MHC typing system for the dog, which is critical to the further development of preclinical studies of hematopoietic stem cell and solid organ transplantation in the canine model.     

Social class and obesity in 12-year-old children in Brussels: Influence of gender and ethnic origin

From their school health files, the body mass index of 2607 children, 1268 boys and 1339 girls, from the Brussels region of Belgium was analysed. The aim was to study the relationship between obesity and social class, gender and nationality. In Belgian girls, the lower their social class, the higher was the prevalence and severity of obesity. There was no such significant relationship in Belgian boys, nor in immigrant children of either sex, although the overall prevalence of obesity was similar in all groups. These results question certain hypotheses proposed to explain the relationship between social class and obesity. Conclusion From early adolescence on, social inequality influences the prevalence of obesity in Belgian girls, but not in Belgian boys nor in immigrant children. Prevention of obesity should take into account the influence of gender, social class and ethnic origin. Received: 21 January 1997 and in revised form: 30 September 1997 / Accepted: 21 October 1997
