Aim of the study: To Evaluate usefulness and reliability cell free DNA as a screening method to identify mothers at risk fetus with trisomy 21, 18, 13, sex chromosomal anomalies other abnormalities.Method: This is prospective observational study conducted Chalmeda Anand Rao Institute Medical Sciences, Karimnagar from period October 2020 2022. Patients were included least one atypical biochemica...
Background and Objective: Down’s syndrome, as the most common chromosomal disorder, is associated with several psychomotor and sensory disorders that can affect the nutritional status of patients. The aim of this study was to determine the nutritional and anthropometric status and taste and smell sensitivity of children with Down syndrome in Ahvaz. Materials and Methods: This cross-sectional...
انسداد حاد سیستم ادراری یکی از علل شایع مراجعه بیماران به کلینیک ارولوژی می باشد. انسداد سیستم ادراری توسط اروگرافی ترشحی و سی تی اسکن (که دارای عوارض ناشی از اشعه یونیزا و عوارض مواد حاجب می باشند)، mri و مواد رادیونوکلئید (که دارای هزینه بالا و صرف وقت زیاد می باشند.) و نیز روشهای تهاجمی نظیر پیلوگرافی آنته گرید و رتروگرید بررسی می گردد. سونوگرافی روشی غیر تهاجمی در بررسی انسادا سیستم ادراری ...
in this study, chromosome analyses were performed on 70 infertile azoospermic and oligospermic (<20 million/ml) men, and also cultures of peripheral blood lymphocytes by high resolution banding method were analysed as well. it is revealed 8 (11.43 percent) men with chromosomal abnormality. there were 31.4 percent patients with azoospermia and 68.6 percent with oligospermia from several thousand...
The number of chromatid breaks in peripheral blood lymphocytes (PBL) after exposure to bleomycin in the S/G2 phase of the cell cycle (in the literature referred to as 'mutagen sensitivity') is associated with an increased risk of environmentally related cancers, including oral cancer. The aim of this study was to elucidate whether mutagen sensitivity measured in lymphocytes actually reflects ch...
uterine leiomyomas/fibroids are the most common pelvic tumors of the female genital tract. the initiators remaining unknown, estrogens and progesterone are considered as promoters of fibroid growth. fibroids are monoclonal tumors showing 40-50% karyo-typically detectable chromosomal abnormalities. cytogenetic aberrations involving chromosomes 6, 7, 12 and 14 constitute the major chromosome abno...
Recent reports have suggested that elevated chromosomal aberration yields following X-irradiation of skin fibroblasts in the G2 phase of the cell cycle are characteristic of affected members of cancer-prone families. These studies propose that this phenomenon is a consequence of impaired DNA repair and might be a useful predictor of genetic susceptibility to cancer. We have tested G2 chromosoma...
Massively parallel sequencing (MPS) of cell-free fetal DNA from maternal plasma has revolutionized our ability to perform noninvasive prenatal diagnosis. This approach avoids the risk of fetal loss associated with more invasive diagnostic procedures. The present study developed an effective method for noninvasive prenatal diagnosis of common chromosomal aneuploidies using a benchtop semiconduct...
