Saudi Society undergoes rapid developments as all Arab countries, a matter that necessitates emphasizing citizenship concepts and values in addition to fostering loyalty among society members with all its various classes. Therefore, the current study aimed at finding out the citizenship level among a sample of Saudi primary school students in Al-Riyadh city. Results showed statistically significant differences between normal and hearing impaired students. Hearing-impaired students out performed normal students. Results also showed that mothers’ nationality (Saudi vs.

With modern technological developments and with the fast expansion of mobile technical equipment, a need arouse to conduct a field study to find out how technology influences various developmental aspects of normal and special needs children at the preschool stage. This study aimed  at finding out the effect of iPad on school preparedness among hearing-impaired school children . In this study, all the children attended the national kindergarten in Al-Riyadh. The study sample was divided into control (7) and experimental (8) group.

Abstract: DNA methylation is one of the epigenetic mechanisms which have been implicated in
cellular differentiation, ageing and disease development. The effect of hypomethylating drug
5-aza-2´deoxycytidine (5-aza dC) on the biosynthetic profile of caudal region chondrocytes from
chick sternum was studied in detail. The chondrocytes in culture were treated with varying doses
of 5-aza dC for 48h and maintained subsequently without the treatment and harvested at
selected time points for analysis of growth and differentiation status. 15μg/ml of 5-aza dC

This study was carried out to explore the effect of DNA hypomethylation on chondrocytes phenotype, in particular the effect on chondrocyte hypertrophy, maturation, and apoptosis. Chondrocytes derived from caudal region of day 17 embryonic chick sterna were pretreated with hypomethylating drug 5-aza-2'-deoxycytidine for 48 hours and then maintained in the normal culture medium for up to 14 days. Histological studies showed distinct morphological changes occurred in the pretreated cultures when compared to the control cultures.
