Retinoic acid level in the retina/choroid is altered in induced myopia models. All-trans-retinol dehydrogenase (RDH8) is an important enzyme of retinoic acid metabolism. This study aimed to investigate the association
of the RDH8 gene with high myopia. Three single nucleotide polymorphisms (SNPs) [RDH851 (rs2233789), RDH8E5a (rs1644731), and RDH855b
(rs3760753)] were selected, based on the linkage disequilibrium pattern of RDH8 from a previous study, and genotyped for 160 Han Chinese nuclear families with highly myopic (−10 diopters or worse) offspring
as well as in an independent group with 166 highly myopic cases (−10 diopters or worse) and 211 controls. Family-based association
analysis was performed using the family-based association test (FBAT) package, and genotype relative risk (GRR) was calculated
using the GenAssoc program. Population-based association analysis was performed using Chi-square test. These SNPs were in
linkage equilibrium with each other. SNPs RDH851 (rs2233789) and RDH8E5a (rs1644731) both did not show association with high
myopia. SNP RDH855b (rs3760753) demonstrated significant association (P=0.0269) with a GRR of 0.543 (95% confidence interval=0.304–0.968, P=0.038). The association became statistically insignificant, however, after multiple comparison correction. Haplotype analysis
did not show a significant association either. Population-based association analysis also showed no significant association
(P>0.05). Our family- and population-based data both suggest that the RDH8 gene is unlikely to be associated with high myopia in Chinese. 相似文献

Do teachers of religion use history in such a way as to challenge the imagination, stir the emotions, and encourage reflection? The author thinks not, but points to ways in which this may be done. 相似文献

The paper attempts to identify the extent to which modes of knowledge can be associated with different patterns of and assumptions about power.It discusses the meanings and scope of power itself, i.e. both within and beyond epistemic communities, as against ‘social robustness’ implying more democratic or inclusive forms of evaluation.It analyses the extent to which knowledge has shifted from an internalist perspective relying on the prestige of epistemic communities towards socially relevant assumptions resting within social contexts. It discusses the factors affecting types of power patterns, such as: the nature of sponsors’ objectives and the uses to which they might put knowledge; epistemic characteristics; the nature of the resource required, and the stage of finalisation reached. It sketches the range of models of sponsorship to which knowledge is subjected – from that of the free standing and autonomous individual through different patterns of sponsorship to the directly managed.It attempts to link these classifications to a range of empirical examples, including the power of knowledge in government and in crossing the boundaries between universities and industry.In discussing the reciprocal relationships between power and knowledge, it accepts that power affects the identification, use and transmission of knowledge. It is concerned, however, to question overdetermined perspectives of the relationships between knowledge and power whose mutual impacts may be strong but not easily predicted or defined. 相似文献

ABSTRACT Studies in several sports have shown the benefits of adapting the playing environment to fit junior players. Frequently the changes are pragmatic choices based on space constraints or existing line markings, or the result of simple scaling based on stature. In this study, a method of scaling the cricket pitch length is presented which is based on the age-specific size and performance of the bowlers and batters. The objective was a pitch length which enabled young bowlers to bowl good length deliveries while releasing the ball at a more downward angle, similar to elite bowlers. The steeper release angle has the benefit of reducing the sensitivity of the ball flight distance to the variability of ball release. Based on data from county standard under-10 and under-11 players a pitch length of 16.22 yards (14.83 m) was calculated, 19% shorter than previously recommended for under-11s in England. A shorter pitch also increases the temporal challenge for batters, encouraging a wider variety of shots and improved anticipation skills. Pitch lengths scaled in this way to fit the players’ abilities as they develop will enable a more consistent ball release by bowlers and more consistent temporal demand for batters. 相似文献
