The human genome and sport, including epigenetics and athleticogenomics: a brief look at a rapidly changing field     

Sharp NC 《Journal of sports sciences》2008,26(11):1127-1133

Since Hugh Montgomery discovered the first of what are now nearly 200 "fitness genes", together with rapid advances in human gene therapy, there is now a real prospect of the use of genes, genetic elements, and/or cells that have the capacity to enhance athletic performance (to paraphrase the World Anti-Doping Agency's definition of gene doping). This overview covers the main areas of interface between genetics and sport, attempts to provide a context against which gene doping may be viewed, and suggests a futuristic legitimate use of genomic (and possibly epigenetic) information in sport.  相似文献

Guidelines for early admission to elementary school     

Theron B. Proctor  John F. Feldhusen  Kathryn N. Black 《Psychology in the schools》1988,25(1):41-43

An early admission procedure is the first step in adjusting formal educational programming to meet the educational, social, and emotional needs of intellectually advanced children. In view of the benefits to the child and potential benefits to society of meeting the intellectually advanced child's needs, it is important that school systems establish early admission policies. This article presents 12 guidelines for processing an early admission applicant.  相似文献   

Assessment of mentally retarded children with the Matrix Analogies Test-Short Form,Draw A Person: A quantitative scoring system,and the Kaufman Test of Educational Achievement     

Peter N. Prewett  Achilles N. Bardos  Jack A. Naglieri 《Psychology in the schools》1989,26(3):254-260

This study examined the utility of the MAT-SF and the DAP: A Quantitative Scoring System as screening instruments for mental retardation. In this study, 46 normals and 39 developmentally handicapped (DH) 4th- and 5th-grade students were group administered both screening tests and individually administered an achievement test, the KTEA. The results found the MAT-SF to correlate significantly with all areas of achievement for both groups, whereas the DAP did not correlate significantly with any areas of achievement for the normal group but correlated significantly with math, but not reading, for the developmentally handicapped students. The results support the use of the MAT-SF as a screening instrument for mental retardation, whereas the usefulness of the DAP is not as clear.  相似文献   

Sex differences and sex bias on the Boehm test of basic concepts: Do they exist?     

A. B. Silverstein  Denise N. Morita  Kymberli A. Belger 《Psychology in the schools》1983,20(3):269-270

Form A of the Boehm Test of Basic Concepts (BTBC) was administered to 180 kindergartners—90 boys and 90 girls. Neither their mean scores nor their standard deviations differed significantly, and the distributions of scores for the two groups were virtually identical. Moreover, the application of three internal criteria for bias yielded totally negative results; thus, there was no evidence of either sex differences or sex bias in the data.  相似文献   

Wishes of fourth-through seventh-grade gifted students     

Frances A. Karnes  Jeffrey N. Wherry 《Psychology in the schools》1981,18(2):235-239

Three wishes and primary wishes of fourth- through seventh-grade gifted students participating in a residential program for the gifted were collected and categorized. The results indicated that males wished for material things more often than did females. With the exception of fourth graders, subjects made altruistic wishes more frequently than any other wish.  相似文献   

The angiogenetic effect of intramuscular administration of b-FGF and a-FGF on cardiac muscle: the influence of exercise on muscle angiogenesis     

Efthimiadou A  Asimakopoulos B  Nikolettos N  Giatromanolaki A  Sivridis E  Lialiaris TS  Papachristou DN  Kontoleon E 《Journal of sports sciences》2006,24(8):849-854

Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective.  相似文献
