background: in algeria, the data on infertility and its various causes are rare. recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyo...
tea (camellia sinensis) is one of the most economically important crops and is considered tobe the national drink of iran. although there has been an intensive cytogenetic study of tea in differentregions of the world, there has been no report from iran. therefore, the present investigation was carriedout in order to present the basic cytogenetical features of various tea cultivators grown in t...
INTRODUCTION Imatinib mesylate, a selective Bcr-Abl tyrosine kinase inhibitor, has proved to be most effective therapy of Philadelphia chromosome-positive chronic myelogenous leukemia. Imatinib induces complete haematological and cytogenetic response in high percentage of patients. OBJECTIVE The aim of this study was to identify potential prognostic factors before beginning treatment with ima...
Research on studying the features of 0.01%, 0.05%, 0.10% and 0.50% epimutagen Triton-X-305 impact at cellular level, which means way identifying viability pollen in plants first generation, cytological analysis chromosomal aberrations cells primary meristem germinal roots during germination bread winter wheat seeds have been conducted. this direction allows us to significantly improve monitorin...
Biological techniques such as Array-Comparative genomic hybridization (CGH), fluorescent in situ hybridization (FISH) and affymetrix single nucleotide pleomorphism (SNP) array have been used to detect cytogenetic aberrations. However, on genomic scale, these techniques are labor intensive and time consuming. Comparative genomic microarray analysis (CGMA) has been used to identify cytogenetic ch...
BACKGROUND Conventional karyotype has an established role in myelodysplastic syndrome (MDS) and is included in the International Prognostic Scoring System (IPSS) for patient risk stratification and treatment selection. Although some chromosomal abnormalities have been well characterized, the significance of several miscellaneous, infrequent, single chromosomal abnormalities remains to be define...
