We prospectively studied 478 patients with megaloblastic anemia living in Tunisia. Overall, 98% of patients had vitamin B12 deficiency. Pernicious anemia accounted for most of these cases, and median age at presentation was 45 years. Megaloblastic anemia occurred in 19 subjects under 15 years of age, and of these, nine had the Immerslund-Graesbeck syndrome.

Saponaria officinalis L. (common soapwort), usually named fuller’s herb, is encountered in most of Europe, Spain, France, Italy, for example, and also Syria North Africa. known the world as an introduced species, often a weed, sometimes cultivated decorative plant. contains large amount saponins, which foam during extraction with water. In addition to common soapwort flavonoids, quillaic acid, ...

UNLABELLED Of the three foot-and-mouth-disease virus SAT serotypes mainly confined to sub-Saharan Africa, SAT 2 is the strain most often recorded in domestic animals and has caused outbreaks in North Africa and the Middle East six times in the last 25 years, with three apparently separate events occurring in 2012. This study updates the picture of SAT 2 phylogenetics by using all available sequ...

We present the first speleothem-derived central North Africa rainfall record for the last glacial period. The record reveals three main wet periods at 65-61 ka, 52.5-50.5 ka and 37.5-33 ka that lead obliquity maxima and precession minima. We find additional minor wet episodes that are synchronous with Greenland interstadials. Our results demonstrate that sub-tropical hydrology is forced by both...

The objective of this investigation was to determine the feasibility of mapping lineaments on Landsat images of ElRouge, and Al-Ghab depressions, north-west of Syria, and to determine the tectonic significance of these lineaments in order to evaluate the capabilities and limitations of spaceborne data to prove that El-Rouge depression is the extension of Al-Ghab depression and both of them in l...

A fully coupled meteorology-chemistry-aerosol model (WRF-Chem) is applied to simulate mineral dust and its shortwave (SW) radiative forcing over North Africa. Two dust emission schemes (GOCART and DUSTRAN) and two aerosol models (MADE/SORGAM and MOSAIC) are adopted in simulations to investigate the modeling sensitivities to dust emissions and aerosol size treatments. The modeled size distributi...

information and communication technologies are a set of tools, machines, technical knowledge, methods and skills to be used for production, trade, processing, storage, recycling, transferring, and transport of “information”. in the globalization process, information has created the possibility for formation of various formal and informal networks by individuals, groups, and even other networks,...

HIV-1 incidence has been increasing more rapidly in the Middle East and North Africa than in any other global region. Despite this trend, HIV epidemiology in the region remains poorly defined. We conducted an analysis of 3284 publicly available HIV-1 sequences from 15 countries in the Middle East and North Africa to better characterize the regional epidemic. A phylogenetic tree based on the rev...
