due to importance of combination therapies in cancer treatment, this study was performed to find the effects of hyperthermia and neutron irradiation and heir combination on the human lymphocytes. blood samples were treated separately with 41.5 °c for 30 and 60 minutes, 43 °c for 15 and 30 minutes, as well as 10 cgy neutron irradiation. they also treated with hyperthermia followed by irradiation...
Early identification of fetuses with chromosomal abnormalities enables health care providers to form an appropriate management plan for each patient. The main objective of this study was to determine the role of ultrasonography in screening and identifying fetuses at risk for chromosomal abnormalities. A retrospective review of 6480 patients from the Obstetrics and Gynecology ward of Firou...
One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...
Background: Chromosomal aberrations can be one of the causes of fertility problems, including infertility or frequent abortions. Identification of chromosomal aberrations by clinical diagnostic techniques has been primarily performed through standard karyotyping. In this screening, the prevalence of these disorders were checking in individuals with fertility problems from west population of Ira...
Interspecific hybridization, polyploidization and transitions from sexuality to asexuality considerably affect organismal genomes. Especially the last mentioned process has been assumed to play a significant role in the initiation of chromosomal rearrangements, causing increased rates of karyotype evolution. We used cytogenetic analysis and molecular dating of cladogenetic events to compare the...
Because of its importance in sugarcane breeding as a source high productivity and adaptability, efforts made to collect, conserve characterize Saccharum spontaneum accessions from different parts the country. Chromosomal diversity correlation with characters recorded during collection this species have been revealed through study 71 clones collected Jharkhand, state located eastern India. A tot...
In a previous study, cells from two dil'ferent pools of C3Hf mouse embryo cells were cultured in chemically defined medium supplemented with dil'ferent types of serum. The type of serum supplement inAuenced the chromosomal characteristics of the cells and also the time of their neoplastic conversion. In testing the cells for evidence of neoplastic conversion, we implanted a large inoculum of ce...
objective: chromosomal aberrations are common causes of multiple anomaly syndromes. recurrent chromosomal aberrations have been identified by conventional cytogenetic methods used widely as one of the most important clinical diagnostic techniques. materials and methods: in this retrospective study, the incidences of chromosomal aberrations were evaluated in a six year period from 2005 to 2011 i...
Fifty-one polycythemia vera (PV) patients were enrolled in the phase I/II clinical study PEGINVERA to receive a new formulation of pegylated interferon alpha (peg-proline-IFNα-2b, AOP2014/P1101). Peg-proline-IFNα-2b treatment led to high response rates on both hematologic and molecular levels. Hematologic and molecular responses were achieved for 46 and 18 patients (90 and 35% of the whole coho...
background chromosomal abnormality plays an important role in different types of miscarriages. objectives the present study was designed to investigation chromosomal anomalies in three groups of couples with recurrent abortion (ra), spontaneous abortion (sa) and still birth (sb). patients and methods in this retrospective study, the frequency of chromosomal aberrations was investigated among 26...
