Poly A RNA status and itsin vitro translation in a rabbit reticulolysate cell free system, were assessed in the skeletal muscle of young boys with Duchenne muscular dystrophy. Compared to normals there is a significant 48% increase in poly A RNA content of dystrophic muscle and its translatability was increased by 56% based on35S methionine incorporation into total protein systhesised. Immunoprecipitation of the translated products with monospecific antibodies showed that there is a 2.6 fold and a 2 fold increase in m and μ calpains respectively. This underlines the importance of both synthetic and degenerative activities in the early pathology in DMD muscle.  相似文献

The purpose of this study was to determine if the frequent use of a targeted, computer software grammar instruction program, used as an individualized classroom activity, would influence the comprehension of morphosyntax structures (determiners, tense, and complementizers) in deaf/hard-of-hearing (DHH) participants who use American Sign Language (ASL). Twenty-six students from an urban day school for the deaf participated in this study. Two hierarchical linear modeling growth curve analyses showed that the influence of LanguageLinks: Syntax Assessment and Intervention (LL) resulted in statistically significant gains in participants' comprehension of morphosyntax structures. Two dependent t tests revealed statistically significant results between the pre- and postintervention assessments on the Diagnostic Evaluation of Language Variation-Norm Referenced. The daily use of LL increased the morphosyntax comprehension of the participants in this study and may be a promising practice for DHH students who use ASL.  相似文献

The efficacy of two intragenic polymorphic markers of factor VIII gene has been examined in Andhra Pradesh population with a view to confirm/revise the strategy for carrier detection that would be precise and economical. The haemophilia A carrier was detected using Bcl I and Xba I polymorphic sites in intron 18 and 22 respectively. The cumulative efficiency of these two sites for detection of carriers is 100% since all 15 families tested were informative for one of these polymorphisms, thus confirming their usefulness for factor VIII gene mutations found in Andhra Pradesh.  相似文献
