A case with Down syndrome presenting 21q22q translocation: Differential diagnosis [21q22q translokasyonu saptanan bir Down sendromu olgusu]
Robertsonian translocations (ROBs) are the most common chromosomal rearrangemets. ROBs are whole-arm rearrangements between the acrocentric chromosomes chromosomes 13, 14, 15, 21, and 22. ROBs can be classified into 2 ... -
Chromosomal abnormalities in cases with congenital malformations
In this study we have investigated the chromosomal constitution of patients with congenital malformations in order to determine chromosomal anomaly frequencies. The conventional GTG banding patterns were routinely employed ... -
Chromosomal abnormalities in couples with recurrent pregnancyloss
Recurrent miscarriages affect approximately 5% of couples trying to establish a family. In this study we have investigated the chromosomal constitution of couples of with recurrent pregnancy losses in order to determine ... -
Comparison of the Myobacterium tuberculosis with the conventional methods
Polymerase chain reaction (PCR), due to its faster response than culture was used for the diagnosis of Mycobacterium tuberculosis. Amplification reactions were performed using primers that amplify a 123 bp fragment of ... -
Cytogenetic analysis results of abortus materials
Approximately 15-20% of all clinically recognized pregnancies are spontaneously aborted at different weeks. Rates of abnormal karyotypes were 50-60% in abortus material. In this retrospective study, we have investigated ... -

Polymorphism in the H-ras proto-oncogene in cases of urinary bladder cancer
Tural Ş.; Güneş S.; Büyükalpelli R.; Bağci H. (2006)Introduction: Ras proteins play role in signal transduction, cell division and differentiation. Ras protein is encoded by a gene located at 11p15.5 in human. The purpose of this study was to investigate the possible ... -
Recurrent miscarriages and balanced translocation t(4;9)(q21;q13)
The structural chromosomal rearrangements are common in general population. Even balanced translocation carriers could have risk for having children with unbalanced chromosomes, they are phenotypically normal. Therefore, ... -
The role of epigenetics in spermatogenesis
Male germ cells have a unique morphology and function to facilitate fertilization. Sperm deoxyribonucleic acid (DNA) is highly condensed to protect the paternal genome during transfer from male to oocyte. Sperm cells undergo ... -
