The azoospermia factor c (AZFc) region on the Y chromosome is a genetically dynamic locus in the human genome. Numerous genomic rearrangements, including deletion, duplication and inversion, have been identified in AZFc. The complete deletion of AZFc can cause spermatogenic impairment. However, the roles of partial AZFc deletions (e.g. b2/b3 deletion) in spermatogenesis are controversial and va...

Objective To develop a multiplex PCR protocol for routine screening of microdeletions on the Y chromosome Methods Five multiplex sets were established and Y chromosome microdeletions screening were carried out in 26 azoospermic men who undertook ICSI and 30 azoospermic men who undertook testicular biopsy. Results In 56 azoospermic men, 5 patients were found with AZFc/DAZ microdeletions, 2 patie...

Background: Sperm chromatin insufficiencies leading to low sperm count and quality, infertility and transmission of chromosomal microdeletion and aneuploidies to next generations can be due to exposure to environmental pollutions, chemicals and natural or manmade ionizing radiation. In this project which has continued for more than 10 years and is unique in many technical aspects in Iran and in...

Received 14 January 1997 Revised version accepted for publication 28 May 1997 Abstract Y chromosome molecular analysis was performed using the STS-PCR technique in 50 patients with oligozoospermia. Microdeletions of interval 6 of the Y chromosome were detected in seven patients, in six ofwhom subinterval E was affected. All patients retained the RBM1 and DAZ genes, while in one deletion involve...

Y chromosome molecular analysis was performed using the STS-PCR technique in 50 patients with oligozoospermia. Microdeletions of interval 6 of the Y chromosome were detected in seven patients, in six of whom subinterval E was affected. All patients retained the RBM1 and DAZ genes, while in one deletion involved the SPGY gene. The size of the deletion was not apparently related to the severity o...

BACKGROUND Complete deletions of the AZFc region in distal Yq are the most frequent molecular genetic cause of severe male infertility. They are caused by intrachromosomal homologous recombination between amplicons--large, nearly identical repeats--and are found in 5-10% of cases of azoospermia and severe oligozoospermia. Homologous recombination may also generate different partial deletions of...

Microdeletions of the azoospermia factor (AZF) regions in the Y chromosome are a well-known genetic cause of male infertility, resulting in impairment of spermatogenesis. However, the partial deletions of AZFc region related to spermatogenetic impairment are controversial. We investigated partial deletion of AZFc region and DAZ copy number in a population of Iranian infertile men and normozoosp...

Türkçede anlam genişletici ya da değiştirici kimi eklerle muhtelif şekillerde teşekkül etmiş olmalarına karşın taban anlamlarına geri dönen ve “döngülü sözcükler” olarak adlandırılabilecek sözcükler vardır. Bu türden sözcüklerin geçirdikleri süreç “anlamsal döngü” adlandırılabilir. “daz ⇔ dazlak” eklemlenmesinde de anlamsal döngü süreci başlamıştır. “Dazlak” sözcüğü tabanı olan “daz” sözcüğüyle...
