background: recurrent spontaneous abortion is one of the diseases that can lead to physical, psychological, and, economical problems for both individuals and society. recently a few numbers of genetic polymorphisms in kinase insert domain-containing receptor (kdr) gene are examined that can endanger the life of the fetus in pregnant women. objective: the risk of kdr gene polymorphisms was inves...

DNA isolated from diabetic BB (BB/Hagedorn) rats was examined for restriction fragment length differences within the major histocompatibility complex (MHC) as compared with nondiabetic (W-subline) BB rats. Polymorphisms were detected using a mouse class I MHC gene as probe. Specifically, a 2-kb BamHI fragment was present in all the nondiabetic rats examined, but absent in the diabetic rats. Sim...

Genomic DNA from five kindreds and two individuals with hereditary elliptocytosis [HE(4.1+)] and a partial deficiency of protein 4.1 [HE(4.1+)] was extracted and probed with a cDNA for protein 4.1. When using a fragment of the cDNA that encompassed the coding region of the gene, two restriction fragment length polymorphisms segregating with protein 4.1 deficiency were found in one kindred when ...

Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by enzymes. RFLP-PCR an easy-to-perform and inexpensive tool for initial analysis SNPs potentially associated with some monogenic diseases, as well in genotyping, genetic mapping, lineage screening, for...

Objective: Our study examines nuclear factor kappa B (NF-қB) and cyclooxygenase-2 (COX-2) polymorphisms in the most common gynecological cancer type, endometrial cancer, relationship between disease parameters these polymorphisms.
 Methods: In our patient group; while 109 patients were examined treated Department of Gynecology Obstetrics, Istanbul Medical Faculty, 106 healthy women without...

We developed mobility shift analysis of single-stranded DNAs on neutral polyacrylamide gel electrophoresis to detect DNA polymorphisms. This method follows digestion of genomic DNA with restriction endonucleases, denaturation in alkaline solution, and electrophoresis on a neutral polyacrylamide gel. After transfer to a nylon membrane, the mobility shift due to a nucleotide substitution of a sin...

several studies have focused on polymorphisms of major histocompatibility complex (mhc) in sheep, ovar-mhc. this molecule plays a pivotal role in antigen presentation for eliciting immune responses against invading pathogens. the best-characterized genetic control of disease resistance and immune response in animals is associated with mhc. numerous molecular genetic investigations have been und...

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for detection of cry11 genes from Bacillus thuringiensis was established. Based on the analysis of conserved regions of the cry11 genes, 2 oligonucleotide primers were designed to amplify a 1459-bp fragment of the cry11Aa gene, and a 1471-bp of the cry11Ba and cry11Bb genes. The amplification products were di...

background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...
