Assessment of psychological disorders in Egyptian children with hearing impairment.

Impairment of hearing is a common birth defect which may be associated with varieties of psychological abnormalities in childhood. Knowledge and research of such issue are much lacking in Egypt; so the aim of the current study was to characterize and assess various psychological co-morbidities which could occur among hearing-impaired children. This prospective study has been conducted on a total of 40 male children, with age range between 7 and 12 years, divided into two groups.

The sensitivity of Na, K ATPase as an indicator of blood diseases.

Background: Blood-related hereditary diseases are widespread in Eastern and SouthWestern regions of Saudi Arabia until recently. In this study, we used Na, KATPase as an enzymatic indicator for the diagnosis of the diseases.

Materials And Methods: Individuals with different blood diseases (iron deficiency (n=13), anemia (n=14), thalassemia (n=16) and sickle cell anemia (n=12) were studied for Na, K-ATPase activity in the plasma membrane of red blood cell and compared with those of the healthy ones (n=20) of the same age and gender living in Jeddah, Saudi Arabia.

Assessment of genetic diversity of sesame accessions collected from different ecological regions using sequence-related amplified polymorphism markers.

Sequence-related amplified polymorphism (SRAP) markers were used to assess the genetic diversity among a collection of 52 sesame accessions representing different geographical environments, including eight Saudi landraces. A combination of seventeen primers generated a high number of alleles (365) with 100% polymorphism. The polymorphic information content (PIC) and primer discrimination power (DP) recorded overall means of 0.
