background : a detailed study of hidden and hard to reach populations in order to identify their characteristics is essential because they endanger the health of the society by their dangerous behaviors. however, sampling in these populations through conventional sampling methods is impossible due to reasons such as being hidden and lacking a precise frame. methods: in this article, applicable ...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
High-throughput sequencing of T cell (TCR) receptor repertoires is a promising approach that can be used to characterize the state and dynamics of adaptive immunity and, potentially, to deduce the antigen specificity of the immune response [1]. While the number of applications of TCR profiling is constantly growing, basic protocols have several drawbacks that are making it difficult to utilize ...
Knowing the population size of rare diseases or special subpopulations like injection drug users (IDUs) is one of the most important challenges in public health and health surveillance systems but it is difficult to estimate these groups. During the last few years, new methods have been suggested to estimate hidden or hard-to-reach populations, one of which is the network scale-up method (NSUM)...
PCR-based mtDNA analysis (RFLP) was used for the study of population differentiation in the Russian sturgeon (Acipenser gueldenstaedti). The mtDNA ND5/6 gene regions were amplified using PCR techniques followed by RFLP analysis. 39 different composite haplotypes were detected among 62 specimens. 29 haplotypes were rare occuring only once in two regions (west and east areas of the Southern Caspi...
