I-37: Genome Instability and DNA Damage in Male Somatic and Germ Cells Expressed as Chromosomal Microdeletion and Aneuploidy Is A Major Cause of Male Infertility

Background: Sperm chromatin insufficiencies leading to low sperm count and quality, infertility and transmission of chromosomal microdeletion and aneuploidies to next generations can be due to exposure to environmental pollutions, chemicals and natural or manmade ionizing radiation. In this project which has continued for more than 10 years and is unique in many technical aspects in Iran and in...

KARYOTYPIC STUDY OF TRIFOLIUM SPECIES AND CULTIVARS IN IRAN

Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, Kordestan, Harati, Enaj and Lordegan), T. repense, T, fragverm, T. prateme and T, alexandrin...

فراوانی آسیب‌های کروموزومی ناشی از داروی بلئومایسین سولفات در سلول‌های هیبریدومای F3B6 و HF2x653 در مقایسه با سلول‌های غیرهیبرید والدی

  Background and Objective: Hybrid cells are made from fusion of two or more somatic cells. After formation chromosomes are located in one membrane . . So nucleic condition of each fused cell has changes and two genomes and chromosomes interact with each other. Locating the genes in new nucleic and cytoplasmic condition and great chromosomal rearrangement in these new formed cells can affect th...

Investigation of the Effect of Exhaust Gas Recirculation (EGR) on pollutants Emission From Si Engine Exhaust Gasese (RESEARCH NOTES)

This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...
