The purpose of this study was to assess the water qualities and genotoxicity of Maheshara Lake situated near Gorakhpur, India. The lake receives many types of pollutants from two industries, agricultural run-off and domestic sewages. A total of five sampling stations were established for measurement of water pollution and the measurement of cytogenetic alterations in vivo is considered an initi...
Background: Myelodysplastic syndromes (MDSs) include a diverse group of clonal bone marrow disorders characterized by ineffective hematopoiesis and pancytopenia. It was found that down regulation of APAF1, a putative tumor suppressor gene (TSG), leads to resistance to chemotherapy and disease development in some cancers. In this study, we investigated the relation of APAF1 methylation status wi...
Background: Prenatal diagnosis for Fetal Chromosomal anomalies currently relies on assessment of risk followed by a combination of biochemical and nuchal translucency. Trisomy 21 is the most common trisomy that is associated with intellectual disability. Pregnant women who receive a prenatal diagnosis of trisomy 21 currently have the option of continuing or terminating their pregnancy, but no f...
background: chromosome abnormality (ca) including sex chromosomes abnormality (scas) is one of the most important causes of disordered sexual development and infertility. scas formed by numerical or structural alteration in x and y chromosomes, are the most frequently ca encountered at both prenatal diagnosis and at birth. objective: this study describes cytogenetic findings of cases suspected ...
Cytogenetic, biomolecular, and clinicopathologic features were retrospectively studied in 34 adult patients with acute myelogenous leukemia expressing one or more of the following lymphoid-associated markers (LMs): CD7, CD2, CD10, CD19, CD22, TdT. Six patients showed 11q23 rearrangements (group I); three patients had the classic Ph chromosome (group II); 15 patients had aberrations of the myelo...
Chronic kidney disease (CKD) is much more common than people recognize, and habitually goes undetected and undiagnosed until the disease is well advanced or when their kidney functions is down to 25% of normal function. Genetic and non-genetic factors contribute to cause CKD. Non-genetic factors include hypertension, High level of DNA damage due to the production of reactive oxygen species and ...
Many biological factors affect radiosensitivity. In this study, radiosensitivity among the different blood groups was investigated. Peripheral blood sample of 95 healthy people were divided into two parts. One part was irradiated with 2 Gy Co-60 gamma rays and the second one was considered as control. Then all the samples were studied by cytokinesis-blocked micronucleus assay (CBMN assay). Our ...
Chronic Myeloid Leukemia (CML) is a hematopoietic malignancy characterized by the presence ofPhiladelphia (Ph1) chromosome that results from balanced reciprocal translocation between chromosomes9 and 22 leading in the formation of bcr/abl fusion gene. The present study was conducted to evaluate cytogenetic and molecular abnormalities in CML patients at presentation and during the co...
BACKGROUND Biomonitoring provides a useful tool to estimate the genetic risk from exposure to genotoxic agents. The aim of this study was to assess the potential cytogenetic damage associated with occupational exposure to hexavalent chromium by using micronuclei (MN) as a biomarker. METHODS This was a cross-sectional study and all participants were males. Both the exposed and control individu...
Inherited bone marrow failure syndromes are a group of rare, heterogeneous genetic disorders with a risk of clonal and malignant myeloid transformation including clonal marrow cytogenetic abnormalities, myelodysplastic syndrome and acute myeloid leukemia. The clinical characteristics, risk classification, prognostic factors and outcome of clonal and malignant myeloid transformation associated w...
