Dynamic changes of the chromosomal aberrations and the DNA damage were analyzed in individuals exposed to low and therapeutic doses of radiation. The investigation included 37 persons living in areas where the radioactive sources were discovered 10-12 years ago. It was established by biodosimetry methods that the examined persons had absorbed dose of 0.2-0.7 Gy or had increased number of chromo...

Acute myeloid leukemia (AML) is a haematological malignancy characterized by the excessive proliferation of immature myeloid cells coupled with impaired differentiation. Many AML cases have been reported without any known cytogenetic abnormalities and carry no mutation in known AML-associated driver genes. In this study, 200 AML cases were selected from a publicly available cohort and different...

Metabolic conversion of oestrogen phenolic groups may create conditions of oxidative stress accompanied by damage of cellular macromolecules including DNA. The aim of this investigation was to evaluate the cell cycle kinetics and possible cytogenetic changes in cultured human peripheral blood lymphocytes exposed to seven experimental concentrations of 17 -oestradiol (range 10 M to 10 M). Cell c...

BACKGROUND Autism is a complex neuropsychiatric disorder that manifests in early childhood. Although the etiology is unknown yet but, new hypothesis focused on identifying the key genes related to autism may elucidate its etiology. The main objective of the present study was to verify the value of karyotyping in autistic children and identifying association between chromosome abnormalities and ...

Investigations of solid tumors have shown that a very specific characterization of aberrant tissues can best be performed using a combination of cytologic, cytogenetic and molecular-cytogenetic methods. Thus, cytological analyses may serve to examine various features of tumors cultivated in vitro, e.g. growth peculiarities, cell morphology, specific details of cell division and mitotic rates, a...

BACKGROUND Children born with congenital anomalies present a very high rate of perinatal death and neonatal mortality. Cytogenetic analysis is a convincing investigation along with clinical suspicion and biochemical screening tests. The current study was designed to characterize the prevalence and types of chromosomal abnormalities in high risk prenatal samples using different cytogenetic techn...

background and objectives: primary amenorrhea is not a disease but a symptom that may result from several quite different causes[nn1] . common hormonal cause of primary amenorrhea includes constitutional delay, hypothalamic –pituitary dysfunction, chronic systemic disease and absent ovarian function. the aim of this study was to estimate the incidence of the chromosomal abnormality referred for...

Background & Objective: Cytogenetic abnormalities in Multiple myeloma (MM) has emerged as the most important factor that determine the prognosis and survival. Fluorescence in situ hybridization (FISH) can detect a greater number of cytogenetic abnormalities as compared to conventional karyotyping and hence has become the standard test in determining genetic abnormalities in MM....

Cutaneous Melanoma (CM) is a leading cause of cancer deaths, with reports indicating a rising trend in the incidence rate of melanoma among Hispanics in certain U.S. states. The level of melanin pigmentation in the skin is suggested to render photoprotection from the DNA-damaging effects of Ultraviolet Radiation (UVR). UVR-induced DNA damage leads to cytogenetic defects visualized as the format...

In the last 30 years, China has undergone one of the largest rural-to-urban migrations in human history, with many children left behind because of parental migration. We present a meta-analytic review of empirical studies on Chinese children's rural-to-urban migration and on rural children left behind because of parental migration. We examine how these events relate to children's emotional, soc...
