OBJECTIVES Normal lung function has been shown to be population specific. The aim of this study was to derive normal reference spirometric values for Omani children and adolescents. METHODOLOGY Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV(1)), peak expiratory flow and forced mid-expiratory flow were measured in 837 healthy Omani(More)
OBJECTIVE To describe the angiotensin converting enzyme (ACE) genotype frequencies among Omani Arabs. METHOD A polymerase chain reaction (PCR) test, based on separation of different size DNA fragments, was developed to test the presence or absence (polymorphism) of a small DNA deletion in the ACE gene. The subjects were 124 Omani Arab students of Sultan(More)
OBJECTIVE To study the applicability of simple field measurements of physical fitness in a sample of Omani boys and their relationships to selected variables. METHOD Two field measures of physical fitness-the time to complete 1.6-km run/walk and the sum of 5 skinfold thicknesses-were correlated with personal and family physical activity-related and other(More)
OBJECTIVE To assess aerobic fitness in male and female adolescents using the multistage 20-metre shuttle run test and correlate it with selected fitness variables. METHOD The subjects comprised 83 girls and 64 boys aged 15-16 years, randomly selected from two segregated government schools in Muscat. After the pupils filled in a short questionnaire on(More)
UNLABELLED Stroke is an important cause of morbidity and mortality worldwide. The case fatality rates from stroke are two- to three-fold higher in sub-Saharan Africa, including Nigeria, than in the developed world, mainly because of limited healthcare facilities and untreated risk factors. The aim was to determine the prevalence of traditional(More)
A new technique of time-domain analysis for screening of Obstructive Sleep Apnea (OSA) using R-R interval (RRI) data is investigated. This method is based on the Statistical Signal Characterization (SSC) of the analytical signal that is generated using Hilbert transformation of the RRI data. The four SSC parameters: amplitude mean, period mean, amplitude(More)
The metabolic syndrome, as defined by the International Diabetes Federation, was investigated in five large, extended, highly consanguineous, healthy Omani Arab families of a total of 1277 individuals. Heritability (h2) of the phenotypic abnormalities that make up the syndrome and other related traits was estimated by variance decomposition method using(More)
The origin of the relative bradycardia found in athletes and in chronically exercised animals is still controversial. To further investigate the role of the autonomic nervous system in exercise bradycardia three groups of Sprague-Dawley rats performed swimming exercises daily for 1.5 hr for a total of 45 hrs. The contribution of the sympathetic and(More)
AIM To investigate the association of 10 known common gene variants with susceptibility to type 2 diabetes mellitus (T2D) among Omanis. METHODS Using case-control design, a total of 992 diabetic patients and 294 normoglycemic Omani Arabs were genotyped, by an allelic discrimination assay-by-design TaqMan method on fast real time polymerase chain reaction(More)
Physical inactivity and ageing are widely recognized as risk factors for development of coronary artery disease. One of the characteristic changes that occurs in aged coronary artery is downregulation of their large-conductance voltage- and calcium-activated K(+) (BK(Ca)) channels. In this study, we investigated the effects of moderate exercise training(More)
