Endothelial cells form a multifunctional cell lining that covers all of the inner surface of blood vessels and regulates several important physiological and pathological reactions. These include inflammation/immune reaction, blood vessel tonus, hemostasis/thrombosis, angiogenesis and so on. Behçet’s Disease (BD) is a chronic, relapsing, multisystemic disorder characterized by urogenital ulcers ...
Since its emergence in South East Asia in 2003, Highly Pathogenic Avian Influenza (HPAI) A/H5N1 has reportedly caused outbreaks in poultry and/or wild birds in 62 countries, of which 24 were in Europe. Interestingly, out of the many genetic clades circulating in Asia, the westward spread of HPAI A/H5N1 to Central Asia, the Middle East, Europe and Africa was dominated by one single clade, namely...
The genetic diversity within an 11 kb segment of the MTMR8 gene in a sample of 111 sub-Saharan and 49 non-African X chromosomes was investigated to assess the early evolutionary history of sub-Saharan Africans and the out-of-Africa expansion. The analyses revealed a complex genetic structure of the Africans that contributed to the emergence of modern humans. We observed partitioning of two thir...
The Levant is a region in the Near East with an impressive record of continuous human existence and major cultural developments since the Paleolithic period. Genetic and archeological studies present solid evidence placing the Middle East and the Arabian Peninsula as the first stepping-stone outside Africa. There is, however, little understanding of demographic changes in the Middle East, parti...
Drawing on 265 national sample surveys spanning 83 countries we find that there was a net decrease in the overall incidence of consumption poverty over 1987-98. But it was not enough to reduce the total number of poor by various definitions. The incidence of poverty fell in Asia and the Middle East—North Africa. It changed little in Latin America and Sub-Saharan Africa, and it rose sharply in E...
BACKGROUND There are no available data concerning the incidence and the clinical pattern of coeliac disease in immigrant children coming to Italy from developing countries. AIMS To evaluate the epidemiological and clinical features of coeliac immigrant children coming to Italy. PATIENTS AND METHODS Hospital records of 1917 children diagnosed in 22 Italian Centres from 1999 to 2001 as having...
Rift Valley fever virus (RVFV), a phlebovirus of the Bunyaviridae family, is an arthropod-borne virus which emerges periodically throughout Africa, emphasizing that it poses a major threat for animal and human populations. To assess the genetic variability of RVFV, several isolates from diverse localities of Africa were investigated by means of reverse transcription-PCR followed by direct seque...
