Assessment of patrilineal gene pool of the Iranian Azeris.

The Iranian Azeris are the largest ethno-linguistic minority in Iran who live mainly in the north-west part of the country. Located in the crossroad of ancient human migrations the Iranian Azeris bear the complicated historical influence of the region in their gene pool. Despite the importance of Iranian Azeris in reconstructing the historical event of the Middle-East, their (genetic) origin still remains heavily disputed. In this study we tried to evaluate the rates of genetic contribution of possible source populations (namely, indigenous Iranian, Caucasian, and Central Asian) in the gene pool of modern Iranian Azeris through paternally inherited Y-chromosomal 6 STR markers. The assessment of genetic distances reveals that the Iranian Azeris are mixed population with substantial North Caucasian genetic contribution being genetically much closer to their immediate neighboring ethnic groups. Based on the results of admixture analysis we can conclude that there are significant Caucasian and no visible Central Asian contribution to the gene pool of modern Iranian Azeris.

Culturally competent occupational therapy in a diversely populated mental health setting.

Cultural sensitivity is a crucial component of health care provision, particularly in psychiatric settings. As society becomes more multicultural, it is essential for occupational therapists to continue to develop cultural competence, which is defined in this paper as an awareness of, sensitivity to, and knowledge of the meaning of culture. At San Francisco General Hospital, an innovative multicultural model consisting of special focus programs is used. The key to the success of such programs is a culturally competent professional staff.

Iranian Azeri's Y-Chromosomal Diversity in the Context of Turkish-Speaking Populations of the Middle East.

BACKGROUND: The main goal of this study was to conduct a comparative population genetic study of Turkish speaking Iranian Azeries as being the biggest ethno-linguistic community, based on the polymorph markers on Y chromosome. METHODS: One hundred Turkish-speaking Azeri males from north-west Iran (Tabriz, 2008-2009) were selected based on living 3 generations paternally in the same region and not having any relationship with each other. Samples were collected by mouth swabs, DNA extracted and multiplex PCR done, then 12 Single Nucleotide Polymorphisms (SNPs) and 6 Microsatellites (MS) were sequenced. Obtained data were statistically analyzed by Arlequin software. RESULTS: SNPs and Microsatellites typing were compared with neighboring Turkish-speaking populations (from Turkey and Azerbaijan) and Turkmens representing a possible source group who imposed the Turkish language during 11-15(th) centuries AD. Azeris demonstrated high level of gene diversity compatible with patterns registered in the neighboring Turkish-speaking populations, whereas the Turkmens displayed significantly lower level of genetic variation. This rate of genetic affiliation depends primarily on the geographic proximity. CONCLUSION: The imposition of Turkish language to this region was realized predominantly by the process of elite dominance, i.e. by the limited number of invaders who left only weak patrilineal genetic trace in modern populations of the region.
