MicroRNA-146a expression and microRNA-146a rs2910164 polymorphism in Behcet's disease patients.

Behcet's disease is a chronic, multisystem, inflammatory disease of unknown etiology. Oral ulcers, genital ulcers, cutaneous lesions, and ocular and articular involvement are the prominent features of the disease. The aim of the study was to assess expression of microRNA-146a and its gene polymorphism in Egyptian Behcet's disease (BD) patients and to evaluate their possible relation with clinical manifestations and activity.

Human blood groups in Dakahlya, Egypt.

New data on blood groups among Egyptians (Dakahlya province) are obtained by studying eight blood group systems: ABO, Rhesus, MNSs, Kell, Duffy, Kidd, P and Lewis. Comparing our results with the data reported in neighbouring countries, we found in Egypt a high frequency of B, NS, cDe and K genes, a moderately high frequency of P and the presence of Fy gene. The Egyptian population appears as a mixture of African, Asiatic and Arabian characteristics.
