The heterozygote-excess method is a recently published method for estimating the effective population size (Ne). It is based on the following principle: When the effective number of breeders (Neb) in a population is small, the allele frequencies will (by chance) be different in males and females, which causes an excess of heterozygotes in the progeny with respect to Hardy-Weinberg equilibrium e...
The pleckstrin homology (PH) domains of a number of proteins have been found to interact in vitro with inositol phospholipids; recent experiments show that these interactions may be important in directing protein translocation to specific parts of the cell following stimulus-induced lipid breakdown or synthesis.
uniparental disomy (upd) is a situation in which both members of a chromosome pair are inherited from one parent. this study has been conducted on a family with a five year-old healthy girl and a mentally retarded boy. the parents were first cousins and they both had robertsonian translocation between their long arm of chromosome 13 and 14 [45, xy t (13q14q)]. their affected son had a similar k...
a large number of simple or complex translocation involving the cml and aml chromosomal abnormalities has been described. this study was aimed to investigate the complex chromosome aberrations in the series of myeloid malignancies including cml and aml. the present report deals analyzed 187 consecutive with cml and aml patients, using methotrexate cell synchronization and un-stimulated cultur...
background: carriers of translocations may have an increased risk of an unbalanced progeny due to imbalances and delays in meiosis. case: a 24-year-old pregnant iranian female was referred to the genetic department of yazd clinical and research centre for infertility because of her pregnancy history. she had three previous pregnancies, two of which ended in abortion. the one live born infant wa...
β-thalassemia is a common inherited disorder worldwide including southern China, and at least 45 distinct β-thalassemia mutations have been identified in China. High-resolution melting (HRM) assay was recently introduced as a rapid, inexpensive and effective method for genotyping. However, there was no systemic study on the diagnostic capability of HRM to identify β-thalassemia. Here, we used a...
Objectives: Excess iron stores have been postulated to enhance the risk of ischaemic heart disease. This study aims to determine whether the two major mutations of the haemochromatosis (HFE) gene (C282Y and H63D) are associated with ischaemic heart disease (IHD) or myocardial infarction (MI). Design: Cross sectional case–control study. Setting: The geographical area studied by the MONICA (monit...
heavy metals such as cadmium mainly enter in the environment and ecosystem as a result of human activities. this study was conducted in order to evaluate the ability of bacterial inoculants to enhance efficiency of phytoextraction in a calcareous soil. three plants (amaranthus retroflexus, helianthus annus and medicago sativa), along with three levels of inoculants and four levels of cd were ev...
plant-based remediation (i.e. phytoremediation) is one of the most significant eco-sustainable techniques to cope with devastating consequences of pollutants. in the present study, the potential of a wetland macrophyt (i.e. potamogeton crispus ) for the phytoremediation of heavy metals (i.e. cu, cr, pb, as and cd) in the anzali wetland was evaluated. the results showed that p. crispus tends to ...
in the present study, a field study was performed on some herbaceous plants growing in thesoutheast of ahvaz, where some metal producing industries are active. the aim of this studywas to investigate and compare manganese (mn) and zinc (zn) accumulation in seven dominantherbaceous plants in this area. plant samples were collected randomly. associated soils weresampled from the same sites next t...
