Extracts of the digestive diverticula of more than 300 individuals from four geographically separated populations of the European oyster, Ostrea edulis L. have been examined by electrophoresis for esterase and phosphoglucose isomerase polymorphisms. Three regions of esterase variability have been detected in the electrophoretograms. It is inferred that the variants in two of these regions are governed by two co-dominant alleles at each of two loci. Two phenotypes of phosphoglucose isomerase, which is inferred to be a dimeric enzyme encoded by two alleles at a single locus, have been observed. Allele frequencies and phenotype distributions are compared in the four populations. It is concluded that the populations differ genetically at the loci investigated, the magnitude of the differences being generally greatest between different 'physiological races'. 相似文献

Nutrigenetic research examines the effects of inter-individual differences in genotype on responses to nutrients and other food components, in the context of health and of nutrient requirements. A practical application of nutrigenetics is the use of personal genetic information to guide recommendations for dietary choices that are more efficacious at the individual or genetic subgroup level relative to generic dietary advice. Nutrigenetics is unregulated, with no defined standards, beyond some commercially adopted codes of practice. Only a few official nutrition-related professional bodies have embraced the subject, and, consequently, there is a lack of educational resources or guidance for implementation of the outcomes of nutrigenetic research. To avoid misuse and to protect the public, personalised nutrigenetic advice and information should be based on clear evidence of validity grounded in a careful and defensible interpretation of outcomes from nutrigenetic research studies. Evidence requirements are clearly stated and assessed within the context of state-of-the-art ‘evidence-based nutrition’. We have developed and present here a draft framework that can be used to assess the strength of the evidence for scientific validity of nutrigenetic knowledge and whether ‘actionable’. In addition, we propose that this framework be used as the basis for developing transparent and scientifically sound advice to the public based on nutrigenetic tests. We feel that although this area is still in its infancy, minimal guidelines are required. Though these guidelines are based on semi-quantitative data, they should stimulate debate on their utility. This framework will be revised biennially, as knowledge on the subject increases. 相似文献
