Estella Nazarova Chromosomal polymorphism in Armenian population of Crepis panno
نویسنده
چکیده
A population of Crepis pannonica, growing in the Hosrov reserve in Armenia, at the southem limit ofthe species ' area, has been investigated over a period ofmore than 20 years. An extraordinary chromosomal polymorphism has been detected by the study of root tip mitoses ofseedlings. 40 different chromosome complement variants were found, including a full range of aneuploids, B-chromosomes, structural heteroand homozygotes, witnessing active chromosomal restructuring and karyotype evolution.

In the present work we evaluated adenosine deaminase 1 (ADA1) encoding gene (ADA1) rs73598374 single nucleotide polymorphism (SNP) and the activity of this enzyme in patients with ischemic stroke (IS) in Armenian population. A total of 98 first episode IS patients within the first 24 hours of stroke onset, and ageand sex matched 177 healthy subjects (control group) were enrolled in this study. ...

The Hamshenis are an isolated geographic group of Armenians with a strong ethnic identity who, until the early decades of the twentieth century, inhabited the Pontus area on the southern coast of the Black Sea. Scholars hold alternative views on their origin, proposing Eastern Armenia, Western Armenia, and Central Asia, respectively, as their most likely homeland. To ascertain whether genetic d...

Introduction Juvenile idiopathic arthritis (JIA) is a childhood onset autoimmune disorder characterized by inflammation of joints and other tissues. The basis for susceptibility to common autoimmune and inflammatory diseases, including JIA, is a complex interplay between multiple genetic and environmental risk factors. NFb appears to be a central player in several autoimmune diseases, according...
متن کاملThe Distribution of Newly Synthesized Dna in Mitotic Division
The chromosomes of Crepis capillaris were labelled with thymidine-2-C(14) in their DNA fraction. Quantitative analysis of the distribution of newly synthesized DNA in postmetaphase stages of the division following the period of label incorporation led to the conclusion that the new DNA is not necessarily equally distributed by the mitotic process and that, therefore, chromosome duplication does...
