the present study was undertaken to examine the efficacy of a treatment regime using a controlled internal drug release (cidr) device in conjunction with injections of gonadotropin releasing hormone (gnrh) and prostaglandin f2α (pgf2α) on conception rate of repeat-breeding iraqi buffaloes. data were collected from 100 buffaloeswith repeat breeding in ninevehprovince housed at six private dairy ...

background: androgens play critical role in secondary sexual and male gonads differentiations such as spermatogenesis, via androgen receptor. the human androgen receptor (ar) encoding gene contains two regions with three nucleotide polymorphic repeats (cag and ggn) in the first exon. unlike the cag repeats, the ggn has been less studied because of technical difficulties, so the functional role ...

purpose : to evaluate indications, risk factors and outcome of repeat penetrating keratoplasty (pkp) at a tertiary referral eye care center methods : in this retrospective study, medical chart of patients who underwent repeat pkp at labbafinejad medical center between january 2004 and december 2009 were reviewed. results : a total of 1,859 corneal transplantations were performed on 1,624 eyes d...

introduction: the examination of radiographics repeat rate and the causes are considered as one of the main factors in assessing the performance of radiographers and the function of the equipments in radiography services. the analysis of repeated films can reveal sources of the errors and areas where improvement can be made. apart from imposing additional charges, the repeats are responsible fo...

The objective of the present study was to determine the grades of nonspecific bacterial infection of genitalia of repeat breeding cattle by a simple and rapid test under field condition. For this purpose, a total of 100 crossbred Jersey cows comprising of 80 repeat breeding animals presented for treatment and 20 normal cyclic (control group) animals presented for artificial insemination at thei...

Background & Aims: Nearly 30 hereditary disorders in humans result from an increase in the number of copies of simple repeats in genomic DNA, including fragile X syndrome, myotonic dystrophy, Huntington’s disease, and Friedreich’s ataxia. One the most frequently occurring types of mutation is trinucleotide repeat expansion. The present study was conducted with the aim of investigating the cause...

objectives: myotonic dystrophy type i (dm1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. dm1 is associated with the expansion and instability of ctg repeat in the 3' untranslated region of the myotonic dystrophy protein kinase (dmpk) gene located on chromosome 19q13.3. the aim of this study was ...

background: the variable numbers of tandem-repeat (vntr) alleles at the phenylalanine hydroxylase (pah) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. this study was carried out to analyze vntr alleles at the pah gene in iranian azeri turkish population. methods: in this study, 200 alleles from general population were studied by pcr. results: the fr...

objective: classic cell culture and karyotyping is routinely used for prenatal detection of different chromosomal abnormalities. molecular cytogenetic techniques have also recently been developed and used for this purpose. quantitative florescence pcr using short tandem repeat (str) markers has more potential for high throughput diagnosis. marker heterozygosity in short tandem repeats (str) is ...
