متن کاملMEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملO-10: PLAP Marker in Testicular Biopsy ofIranian Men by Immunohistochemistry Methodfor Early Diagnosis of Testicular Carcinomain Situ
Background: Testicular Carcinoma in situ (CIS), also known as intratubular germ cell neoplasia (ITGCN), is a pre-invasive precursor of testicular germ cell tumours (TCGTs), i.e seminomas and non-seminomas -the commonest cancer type of male adolescents and young adults- which can be diagnosed using a surgical biopsy. Infertility is one of the condition known to predispose to TGCT, but based on s...
متن کاملAnalyses of meiotic chromosomes in testicular biopsies of infertile patients.
Between 1989 and 1992 meiotic chromosome studies and synaptonemal complex analyses were evaluated using light and, in part, electron microscopy in 46 infertile males with highly abnormal spermiograms. This examination focused on whether the breakdown of spermatogenesis could be attributed to pairing anomalies of bivalents. The study of meiotic chromosomes and synaptonemal complexes indicated no...
