Students whO are deaf and hard of hearing (DHH) face challenges in learning to read. Much has been written about the relative importance of the different factors associated with success in reading, but these factors are disputed within the literature on DHH readers. The Center on Literacy and Deafness, funded by the Institute of Education Sciences, is(More)
PURPOSE This study evaluated psychometric properties of 2 phonological awareness (PA) tests normed for hearing children when used with deaf and hard-of-hearing (DHH) children with functional hearing. It also provides an in-depth description of these children's PA. METHOD One hundred and eight DHH children (mean age = 63.3 months) with cochlear implants or(More)
Better understanding the mechanisms underlying developing literacy has promoted the development of more effective reading interventions for typically developing children. Such knowledge may facilitate effective instruction of deaf and hard-of-hearing (DHH) children. Hence, the current study examined the multivariate associations among phonological(More)
The requirement for ATP hydrolysis in the initiation of RNA polymerase II (Pol II)-directed transcription and the relationship between ATP and novobiocin action led us to investigate whether novobiocin could inhibit transcription of the mouse metallothionein-I (MT-I) gene. Novobiocin inhibited the MT-I gene transcription in a fractionated rat hepatoma(More)
An in vitro transcription system was developed from H411EC3 (H4) hepatoma cells, which mimics the in vivo up-regulation by glucocorticoid hormones on ribosomal RNA (rRNA) synthesis. Ribosomal DNA (rDNA) transcription in extracts derived from H4 cells grown in the presence of 100 nM triamcinolone acetonide was 4- to 5-fold greater than that in extracts(More)
A hybridoma secreting monoclonal antibodies against RNA polymerase I was produced by the fusion of myeloma cells with spleen cells from a nonimmunized MRL/lpr mouse which is known to produce autoantibodies to RNA polymerase I. The antibodies (McAb-2D11) belong to the IgG2b subclass, reacted specifically with the second largest (120 kDa) subunit of RNA(More)
The effect of novobiocin, a coumarin class antibiotic, on rat ribosomal gene (rDNA) transcription in a fractionated extract derived from adenocarcinoma ascites cells (fraction DE-B) was studied. This drug inhibited transcription of rDNA by blocking initiation of transcription, whereas it had no effect on the elongation of the rRNA transcript. Order of(More)
OBJECTIVES Emerging evidence suggests that early phonological awareness in deaf and hard-of-hearing (DHH) children with functional hearing is significantly related to their reading acquisition, and the assessment of phonological awareness can play a critical role in preventing reading difficulties. Validation of the scores obtained from standardized(More)
The differential transcription of the cloned mouse metallothionein-I (MT-I) gene in tissues was studied in unfractionated and fractionated nuclear extracts from rat liver and brain. MT-I gene transcription was 10-fold greater in liver nuclear extract than in brain nuclear extract, whereas the level of transcription of the histone H4 gene was almost(More)
Nuclear extract from Morris hepatoma 3924A was fractionated by DEAE-Sephadex chromatography. The fraction eluting with 300 mM (NH4)2SO4 (DE-C) was used for transcribing cloned mouse metallothionein-I (MT-I) gene in a run-off assay. This fraction contained the majority of RNA polymerase II as well as the transcription factor(s). Accuracy of MT-I DNA(More)
