Background Familial hypercholesterolemia (FH) is a well-understood Mendelian disorder that increases the risk of cardiovascular disease (CVD), a leading cause of mortality in Middle Eastern and North African (MENA) countries. Objective Review the reporting status of FH mutations across MENA and propose a systemic and strategic method for building a MENA FH registry. Methods Systematic literature search for statistics pertaining to CVD and comparison of number of FH mutations reported in MENA countries and countries with established FH registries. Results Only 57 mutations were reported in 17 MENA countries, whereas more than 500 mutations reported in 3 Western countries. Mortality rates due to CVD were significantly higher in MENA countries compared with Western countries. Conclusions The relatively low reporting of FH mutations in the consanguineous MENA communities with higher prevalence of arabic 17 English 101

Despite the relative abundance of sunny weather, surprisingly, there is increasing evidence that vitamin D deficiency is extremely prevalent in females of reproductive age in Middle East countries. There is also increasing interest in the non-classical roles of vitamin in health and disease including its relation to incidence of gestational diabetes, its impact on glycaemic control in diabetes mellitus, and its association with some complications of pregnancy like preeclampsia. The objective of this study was to estimate the prevalence of Vitamin D deficiency in pregnant diabetic patients in west Libya and analyse potential links to socioeconomic and cultural factors. This is a cross sectional observational study. Random plasma was collected form expected mothers attending the Antenatal Diabetes Clinic at Tripoli’s Main Maternity Hospital. Demographics and socioeconomic and cultural factors were recorded at the same time. Samples were analysed for vitamin D level and biochemical screening panel. Vitamin D level was obtained from 160 patients (mean age 35 years). Over all 95 % of the study population had vitamin D levels below normal (defined as vitamin D level of < 20 ng/mL). Results were subcategorised into severe deficiency ( 30 ng/ml, only 1.3%, 2 patients). All patients were taking daily vitamin D Supplements at a dose of 400 IU as per hospital policy. Vitamin D deficiency is extremely prevalent in pregnant diabetic patients in Libya. There is no clear association with socioeconomic risk factors like employment, type of accommodation or geographic distribution. However, most of the study population had life style characterized by minimal exposure to direct sun arabic 11 English 70

The GC-box is an important transcriptional regulatory element present in the promoters of many mammalian genes, and is found in most, if not all, oxidative phosphorylation (OXPHOS) promoters. In the present study we examine the effects of three Sp1 family members (Sp2, Sp3, and Sp4) on the adenine nucleotide translocase 2, cytochrome c1, F1-ATPase β-subunit, and the mitochondria transcription factor (mtTFA) promoters in Drosophila SL2 cell line. Sp3, like Sp1, strongly activates transcription all four promoters. SP4 stimulates, moderately, but Sp2 had no effect. In addition, Sp3 can, like Sp1, inhibit transcription from the proximal promoter of the ANT2 gene through binding to the Cbox GC element. By contrast, Sp4 and Sp2 do not repress promoter activity. Furthermore, since Sp4 and Sp2 bind to the Cbox repression element on the ANT2 promoter, but do not repress transcription, inhibition of transcription … arabic 21 English 97
