BackgroundAttention deficit hyperactivity disorder (ADHD), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. The aim of this study was to examine the association of -141 polymorphisms in DRD2 gene with ADHA among Iranian-Azeri population.Materials and Methods A case–control association study included 153 patients with attention defi...

HPV infections are common and the presence of the same high-risk type in cervical specimens can be due to reinfection or persistence. Persistent infection is the most important predictor for development of cervical carcinoma. The aim of this study was to validate PCR-RFLP with two sets of primers: MY09/MY11 that amplify a fragment of L1 and P1/P2 that amplify a fragment of E1 ORF. PCR product o...

Two polymorphic marker genes, merozoite surface protein 3α (PvMSP3α) and merozoite surface protein 3β (PvMSP3β), from 100 Plasmodium vivax field isolates, were investigated using polymerase chain reaction and restriction fragment length polymorphism (PCR/RFLP). Genotyping of PvMSP3α and PvMSP3β revealed marked polymorphisms in length and sequence. Three major types of PvMSP3α (Type A, B and C) ...

Introduction: Dicrocoeliasis is a common disease of bile ducts and gallbladder of domestic and wild ruminants. This disease is caused by different species of dicrocoelium including Dicrocoelium dendriticum. The aim of this study was to identify pathological damages and molecular features associated with this parasite in ruminants. Materials and Methods: In this cross-sectional study, 180 fresh...

To prevent distribution of recessive alleles in dairy herds all bulls used for AI (Artificial Insemination) haveto be tested. In this study 26 blood and 4 semen samples were supplied from Iranian Holstein bulls used forAI. Genomic DNA was extracted from 100 μl of blood and 200 μl of semen. Samples were tested by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR...

Combinations of 10 Cryptosporidium parvum oocysts, with various ratios of genotype I to genotype II, were isolated and subjected to PCR-restriction fragment length polymorphism analysis. Amplification of both genotypes in these samples ranged from 31 to 74% and yielded no information about the genotype proportions. In addition, since both genotypes were not always detected, amplification of a s...

a polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) test was performed to investigate the allele frequencies of the insulin-like growth factor (igf1 and igf2 genes) in 90 broilerchickens. a 793 bp fragment of igf1 gene and 1146 bp fragment of igf2 gene were amplified and digested with hinfi and hsp92ii restriction enzymes,respectively. two types of alleles of a and b...

Biochemical polymorphism study is a method of determination of genetic variation. This variability could be a basis for selection and subsequent genetic improvement in farm animals. The polymorphism in the intron 1 of chicken growth hormone (cGH) gene was investigated in the Iranian native fowls by using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. The...

Background: Staphylococcus aureus is a common pathogen in human that can be the cause of a wide range of infectious diseases including bacteremia, pneumonia, cellulitis, and osteomyelitis and skin and soft tissue infections. The coagulase enzyme is one of the most important virulence factors of this bacterium. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) Coa...
