شمارش کروموزومی برای دو گونه بومی از ایران برای اولین بار صورت گرفت. نمونه ها از رویشگاه های طبیعی جمع آوری شدند. paronychia kurdica (18=n2) ازخانواده caryophyllaceae و salsola yazdiana (18=n2) از خانواده chenopodiacea در این تحقیق مورد بررسی قرار گرفتند. برای هر گونه ایدیوگرام رسم شد. کروموزومهای هر دو گونه متاسانتریک بودند.
The World Health Organization reported that air pollution in 2012 caused the death of about 7 million people worldwide (WHO, 2014), confirming as one principal environmental health risks world, and indicating its reduction an urgent mission to save millions lives [...]
this study is an attempt to evaluate the biomonitoring capabilities of rock oyster, saccostrea cucullata, for mercury (hg) pollution. the oyster and sediment samples were collected from 10 rocky habitats of qeshm and hormoz islands in the persian gulf. the concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. biota-...
Soils are three-dimensional (3D) natural bodies conSlStmg of unconsolidated mineral and organic materials that form a continuous blanket over most of the earth's land sUlface. At all scales of measurements, soils are exceedingly complex and variable in bio logical, chemical, physical, mineralogical, and electromagnetic properties. These properties influence the propaga tion velocity, attenuatio...
Reciprocal chromosome translocations, especially balanced rearrangements are known to be one of the main causes of recurrent miscarriage. In this case report, we performed the clinical and cytogenetic analysis on a young couple with two pregnancy losses. Though the couple had a normal clinical study, the cytogenetic analysis revealed a balanced reciprocal translocation of t(2;14)(q11;q24) where...
The EU COST Action DNAqua-Net has since its start in 2016 gathered European researchers with the quest to standardize and implement DNA-based aquatic biomonitoring. On March 9–11, 2021, their work culminated first conference. Here, an astounding 1500 participants from around world virtually share research on biomonitoring encompassing DNA reference databases, field laboratory protocols, data an...
Estimation of population exposure and biological impact of potential hazards are central reasons for performing biomonitoring. The sensitivity of the biomonitoring methods and the linkage of the measured phenomenon to human disease are also important, but often overlooked, considerations. We are conducting experiments to evaluate the sensitivity of hprt mutation measurement in the nonhuman prim...
