Introduction: Congenital long QT syndrome (LQTS) is a cardiac disorder characterized by QT interval prolongation at basal ECG. Different LQTS genes encode ion channel subunits or proteins involved in regulating cardiac ionic currents. Long QT syndrome type 6 (LQT6) is caused by mutation in the KCNE2 gene. Our research aimed to analyze genetic variants of KCNE2 gene causing the disease in Irania...

BMP15 and GDF9 are two oogenesis specific genes play a pivotal role in female fertility in mammals and potential for improvement of prolificacy in marker-assisted selection. The aim of present research was to investigate the variation and association between BMP15 and GDF9 polymorphism and litter size in Markhoz goats. The sequence variability of the different amplified fragments utilized for g...

Background: Cellular tolerance to heat stress is mediated by shock proteins (HSPs). The HSPs act as molecular chaperones and are transcribed in response stress. Among different families of these proteins, HSP70 considered be related the development temperature tolerance. Unraveling polymorphism protein genes could a step towards identification genetic markers for selecting heat-tolerant cattle....

background and objectives: resistance in mycobacterium tuberculosis is caused by mutations in genes encoding drug targets. investigators have already demonstrated the existence of mutations in codons 88 to 94 in the gyra gene and also in codons 1400, 1401, and 1483 of rrs gene among extensively and extremely drug resistant tuberculosis (xdr & xxdr-tb) strains. the aim of this study was to ident...

We have performed analyses of single-strand conformation polymorphisms (SSCP) of the promoter region and the translated parts of the 18 exons of the low-density lipoprotein receptor (LDLR) gene. DNA from 20 unrelated familial hypercholesterolemia (FH) patients was studied. Four different running conditions were used for the nondenaturing gel electrophoresis to systematically evaluate how differ...

The objective of this study was to search for single nucleotide polymorphism (SNP)-type polymorphisms in the dopamine D1 receptor in West Azerbaijani native chicken and look for their association with egg production and body weight traits of chickens by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). For this purpose 180 blood samples were taken from nativ...

We successfully cloned the Wistar-Imamichi (WI) rat growth hormone gene (GenBank accession: GQ890681), which contained 5 exons and 4 introns. Using the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) technique, a novel missense substitution single nucleotide polymorphism was identified and tested for Hardy-Weinberg equilibrium with the χ(2) test. This gene fragment ...

Abstract Background Stigma associated with mental disorders is rooted among many pharmacists, and represents a major barrier to patient support in community-based psychiatry. We developed an assessment scale that specifically designed assess the level of stigma pharmacists may have toward schizophrenia, then examined effects reducing educational program focuses on communication patients diagnos...

We have identified 12 kinds of genetic mutations of butyrylcholine esterase (BCHE) from phenotypic abnormalities, showing that BCHE activities were deficient or diminished in sera. These genetic mutations, detected by PCR-single-strand conformation polymorphism analysis and direct sequencing, consisted of one deletion (BCHE*FS4), nine missense (BCHE*24 M, *1005, *250P, *267R, *330I, *365R, *418...
