Aim. Fertility disorders are one of the most common problems reproductive medicine. Chromosomal abnormalities play a crucial role in failure. The main purpose our study was to determine types and frequency chromosomal aberrations couples with history infertility. Methods. Karyotyping performed 652 failure between 2004 2022, including 203 primary infertility (PI), 240 recurrent pregnancy loss (R...

Dedifferentiated liposarcoma (DDLS) is a malignant adipocytic tumor showing transition from an atypical lipomatous tumor (ALT)/well-differentiated liposarcoma (WDLS) to a non-lipogenic sarcoma of variable histological grades. We present the immunohistochemical, cytogenetic, and molecular cytogenetic findings of DDLS arising in the right chest wall of a 76-year-old man. Magnetic resonance imagin...

Cytogenetic abnormalities at diagnosis are important prognostic indicators in acute myeloid leukemia (AML). AML is categorized into 3 risk groups according to cytogenetic abnormalities; favorable, intermediate, and unfavorable. A new cytogenetic risk group called the monosomal karyotype (MK) had been identified in AML in the unfavorable cytogenetic risk group. The MK was reported to be associat...

BACKGROUND Cytogenetic abnormalities have been described in a few patients with otherwise typical severe aplastic anemia (SAA), and the possible clonal nature of this disease is a controversial issue. MATERIALS AND METHODS Sixty-nine patients with acquired severe aplastic anemia underwent cytogenetic examination on bone marrow cells at the time of diagnosis (n = 34) and/or at least twice afte...

To determine the incidence of leukemiaspecific rearrangements, 60 cases of childhood acute myeloblastic leukemia and transient myeloproliferative disorder were screened with a novel multiplex reverse transcriptase–polymerase chain reaction (RT-PCR) assay, and the results were correlated with the cytogenetic findings. The RT-PCR assay detects 28 different fusion genes and more than 80 different ...

Lymphoma is the most frequently diagnosed hematopoietic malignancy in dogs. Untreated, the survival times are approximately one month. Chemotherapy is the current standard of care and can initiate and temporarily maintain remission, with average remission times of one year. Canine lymphoma is an established model of human non-Hodgkin's lymphoma, and studying this disease in dogs can provide ins...

BACKGROUND AND AIMS The obstetric care of a pregnancy, as it is practiced today, includes non-invasive screening approaches as well as invasive procedures for the definitive prenatal diagnosis of fetal disorders correlations between indications for prenatal cytogenetic diagnosis and results of the chromosomal analysis made upon fetal cells. The aim of our study was to evaluate the correlations ...

PURPOSE The objective was to determine the characteristics and prognostic factors of 86 Chinese patients with trisomy 8 aberrations and compare the prognostic value of International Prognostic System (IPSS) and Revised IPSS (IPSS-R) in this cohort. MATERIALS AND METHODS A total of 86 cases diagnosed with primary myelodysplastic syndromes (MDS) with isolated tr8 or with tr8 and other additiona...
