background human t-cell lymphotropic virus types ι and ιι (htlv-ι and htlv-ii) are deltaretroviruses which may cause leukemia, lymphoma and htlv-associated myelopathy/tropical spastic paraparesis (ham/tsp). in addition, htlv-1 may be related to thalassemia and hemophilia cases after blood transfusion. objectives the aim of this study was evaluation of the prevalence of htlvs in patients with he...

The reported genome-walking methods still suffer from some deficiencies, such as cumbersome experimental steps, short target amplicon, or deep background. Here, a simple and practical fork PCR was proposed for genome-walking. employs primer set of three random oligomers to implement walking task. In primary PCR, the low-stringency amplification cycle mediates binding places on genome, producing...

Unlocking the vast genomic diversity stored in natural history collections would create unprecedented opportunities for genome-scale evolutionary, phylogenetic, domestication and population genomic studies. Many researchers have been discouraged from using historical specimens in molecular studies because of both generally limited success of DNA extraction and the challenges associated with PCR...

Abstract Meat traceability and certification increase consumers’ confidence in making purchasing decisions. In Brazil, certified Angus beef follows specific regulation, which requires a minimum of 50% genome its breed composition to be commercialized as beef. Because the majority produced Brazil is Nellore-based, objective this study was estimate Nellore genetic contribution over sold using tra...

Genome-wide DNA hypomethylation is associated with a worse prognosis in early-stage colorectal cancer. To measure genome-wide DNA methylation levels, long interspersed nucleotide element (LINE-1) repeats are used as a surrogate marker. Cohort studies on the clinical impact of genome-wide DNA methylation level in patients with only early-stage colon cancer, are currently lacking. This study aime...

AB Archival samples represent a significant potential for genetic studies, particularly in severe diseases with risk of lethal outcome, such as in cancer. In this pilot study, we aimed to evaluate the usability of archival bone marrow smears and biopsies for DNA extraction and purification, whole genome amplification (WGA), multiple marker analysis including 10 short tandem repeats, and finally...

decrease in genome content may play a role in environmental adaptation. many studies were reported significant correlation between genome size, weather condition and germination percentage. relative genome content and its correlation with seedling establishment of 14 populations of tall fescue collected from various regions in iran and two commercial tall fescue cultivars were studied under dro...

Mitochondrial genomes in plants are larger and more complex than in other eukaryotes due to their recombinogenic nature as widely demonstrated. The mitochondrial DNA (mtDNA) is usually represented as a single circular map, the so-called master molecule. This molecule includes repeated sequences, some of which are able to recombine, generating sub-genomic molecules in various amounts, depending ...

Clustered regularly interspaced short palindromic repeats/CRISPR associated nuclease 9 (CRISPR-Cas9) system was instigated first into eukaryotes in the last ten years are becoming productive and worldwide application for genome modification. Genome engineering through insertion of foreign DNA insert have numerous disadvantages which could be overcome by use DNA-free editing. Various ways editin...
