Để nhận biết các đặc điểm lâm sàng, cận sàng và xác định bất thường di truyền liên quan đến tình trạng OAT, chúng tôi tiến hành nghiên cứu trên 253 bệnh nhân nam vô sinh mắc hội chứng OAT. Kết quả cho thấy tuổi trung bình của trong là 29,3 ± 6,04 tuổi. Tiền sử viêm tinh hoàn do quai bị, giãn tĩnh mạch chiếm tỉ lệ khá cao, lần lượt 12,65% 23,32%. Nồng độ hormon FSH, LH, Testosterone huyết thanh ...
AZF and DAZ gene copy-specific deletion analysis in maturation arrest and Sertoli cell-only syndrome
The patient was diagnosed with nonmosaic 47, XXY Klinefelter Syndrome with the AZF deletion absent and SRY+. The nonmosaic 47, XXY karyotype was confirmed on a skin biopsy chromosomal analysis. Using only ejaculate motile sperms, 11 oocytes underwent ICSI and were placed rapidly in a time lapse (Embryoscope ©) with a specific culture dish. Biopsies were performed on six embryos on the 3rd day, ...
The natural transmission of microdeletions of the Y chromosome is occasionally reported in the literature. Here we describe the natural transmission of a partial AZFb deletion over three generations. PCR amplification of several sequence tagged site markers in the three AZF regions of the Y chromosome was carried out in a patient with oligoasthenoteratozoospermia, his father and his naturally c...
In mammals, adrenal zona fasciculata (AZF) cells of the adrenal cortex secrete glucocorticoids in a diurnal pattern in response to stimulation by adrenocorticotropic hormone (ACTH). Superimposed on this basal secretory pattern, physical and psychological stress triggers bursts of ACTH-stimulated cortisol production by activation of the hypothalamic pituitary adrenal axis (Stewart and Krone, 201...
سابقه و هدف: آترواسکلروز یک بیماری مهم و شایع قلبی عروقی و نخستین عامل مرگ و میر به ویژه در جوامع صنعتی است. بررسی نقش عواملی مانند آنزیم ها، لیپیدها و لیپوپروتئین ها، آزاد ریشگان، پراکسیداسیون لیپیدها و فاکتور های انعقادی در رخداد آترواسکلروز دارای اهمیت زیادی است. این پژوهش با هدف تعیین مقادیر فاکتورهای انعقادی در مبتلایان به آترواسکلروزیس انجام گرفت. مواد و روش ها: این پژوهش در بخش قلب و عرو...
Genomic DNA of a patient diagnosed with nonobstructive azoospermia and with the history of allogenic bone marrow transplantation from his sister due to chronic myeloid leukemia was isolated from peripheral blood in order to screen Y chromosome microdeletions. 13 short tagged sites belonging to AZF a, b, and c loci were detected with multiplex polymerase chain reaction technique. Bands were dete...
BACKGROUND On 21 September 2001, a huge explosion occurred in a chemical plant in Toulouse. The hypothesis of the study was that the level of depressive symptoms after an industrial disaster would be related to the intensity of exposure and the characteristics of the exposed population, as well as to the consequences of the disaster during the following months. METHODS A random sample of the ...
In a large collaborative screening project, 370 men with idiopathic azoospermia or severe oligozoospermia were analysed for deletions of 76 DNA loci in Yq11. In 12 individuals, we observed de novo microdeletions involving several DNA loci, while an additional patient had an inherited deletion. They were mapped to three different subregions in Yq11. One subregion coincides to the AZF region defi...
We describe a 28 year old male with a pseudodicentric Y chromosome who suffered from azoospermia attributed to maturation arrest of the primary spermatocyte, as diagnosed by testicular biopsy. Chromosome analysis, using G, Q and C banding techniques, revealed an abnormal karyotype of 45,X[7]/46,X,psu dic (Y)(pter-->q11.2::q11.2-->pter)[33]. Polymerase chain reaction (PCR) DNA analysis did not d...
