the isolation-by-distance theory states that the genetic differentiation between individuals raised by increasing geographic distance. therefore, this study tested this hypothesis for garra rufa , a freshwater fish species of iranian inland waters, from six rivers located at the different distances in tirgis basin. for this purpose, eight variable microsatellite loci were applied to identify ge...

background:â there is a relationship between specific genotypes of helicobacter pylori caga and vaca genes and the increased risk of peptic ulcer diseases and gastric cancer. these genes also possess strong patterns of geographical differentiation. the present study aims to determine the patterns of variation of the virulence genes in iran and their association with clinical status. materials a...

background: the present study was formulated in order to determine pol­ymorphism of dihydropteroate synthetase gene (dhps) of plasmodium vivax (p . vivax ) in hormozgan province, southern iran and mutations at codons 382, 383, 512, 553, and 585 associated with resistance of p. vivax to sulfadoxine. method : one-hundred eighteen isolates of p. vivax were prepared within 2007-2008 to determine di...

the objective of the present study was to evaluate the genetic structure and diversity of 16 generations of native fowls of west azerbaijan province, iran using the pedigree data collected between 1994 and 2012. inbreeding coefficient (f), pedigree completeness index (pci), parameters of the probability of gene origin and other parameters related to the genetic structure were estimated using th...

background genetic diversity has provided plasmodium falciparum with the potential capacity of avoiding the immune response, and possibly supported the natural selection of drug or vaccine-resistant parasites. merozoite surface protein-3 (msp-3) has been used to develop vaccines and investigate the genetic diversity regarding p. falciparum malaria in iran. objectives the main goal of this study...

The common buzzard (Buteo buteo) is a bird of prey with Eurasia distribution. Buteo buteo from Iran, has an important role in the ecological cycle of the north and the northwest parts of Iran, now is suffering from illegal hunting. Blood samples from 50 Buteo buteo birds from rehabilitation center of Pardisan Park, Tehran, Iran were taken to evaluate and study the gen...

In this paper possibility of synchronous generator dynamic parameters estimation via On-Line Field Tests using Genetic Algorithm in a 400MVA synchronous generator in BISOTUN power plant in IRAN has been presented and simulated. On-Line (RTDR) time domain data are acquired by generator disturbance simulation. The direct and quadrature-axis dynamic parameters are found by processing the step resp...

Epidemiologic and genetic/molecular research on glaucoma in Iran started within the past decade. A population-based study on the epidemiology of glaucoma in Yazd, a city in central Iran, revealed that 4.4% of studied individuals were affected with glaucoma: 1.6% with high tension primary open angle glaucoma (POAG), 1.6% with normal tension POAG, and 0.4% each with primary angle closure glaucoma...
