in the present paper, the cytogenetic study including meiotic chromosome number and behavior along with pollen viability were performed in 4 populations of trigonella spruneriana boiss. this is the first cytogenetic report of the taxon. all populations are diploid and possess 2n = 2x = 16 chromosome number, which is consistent with the proposed basic number of x = 8. in addition, some meiotic i...
A new zero–inflated Poisson model is introduced for cytogenetic estimation of partial body radiation dose and fraction of the body irradiated. Bayes factors are also presented to detect if a sample of chromosomal aberrations in blood cells results from partial or whole body irradiation. One example of simulated cytogenetic exposure is shown to demonstrate the usefulness of this methodology in c...
Cytogenetic analysis has not only provided important information on the pathogenesis of soft tissue tumors but, by disclosing distinct chromosomal rearrangements in different histopathological entities, has also come to serve as a valuable diagnostic tool. Little is known as yet about the potential prognostic impact of cytogenetic features detected in these tumors. A total of 239 benign and 221...
We treated 261 patients with Philadelphia chromosome (Ph)-positive chronic myeloid leukemia (CML) in chronic phase after failure of IFN-alpha with the Bcr-Abl tyrosine kinase inhibitor imatinib mesylate (400 mg/day given p.o.) and analyzed hematological and cytogenetic responses, long-term prognosis, factors associated with achievement of major cytogenetic response and survival, and comparative...
Background. Diffuse large B-cell lymphoma (DLBCL) accounts for up to 40% of all non-Hodgkin’s lymphomas diagnosed in the western hemisphere. Determination of the gene expression profile has confirmed the physiological heterogeneity of the disease and defined three molecular prognostic subgroups – germinal center B-cell-like (GCB), activated B-cell-like (ABC) and primary mediastinal B-cell lymph...
In 2004, we reported the short-term results of a multicentric, phase 2 study of imatinib 400 mg daily and pegylated interferon-alpha in the treatment of 76 early chronic phase Philadelphia-positive chronic myeloid leukemia patients. In this report, we update the results with an observation time of five years. After two years of treatment, all but 10 patients (13%) had discontinued pegylated int...
