AIM To characterise the genomic DNA (gDNA) yield from urine and quality of derived methylation data generated from the widely used Illuminia Infinium MethylationEPIC (HM850K) platform and compare this with buffy coat samples. BACKGROUND DNA methylation is the most widely studied epigenetic mark and variations in DNA methylation profile have been implicated in diabetes which affects approximat...
BACKGROUND Discovery of short cell free fetal DNA (cffDNA) fragments in maternal plasma has created major changes in the field of prenatal diagnosis. The use of cffDNA to set up noninvasive prenatal test is limited due to the low concentration of fetal DNA in maternal plasma therefore, employing a high efficiency extraction method leads to more accurate results. The aim of this study was to eva...
This paper describes development and initial results for a small prototype superconducting undulator with a period less than 1 cm, referred to here as a “supermini” undulator. The development of superconducting mini-undulators started in the early 1990s with work at BNL and KIT (Germany). In 1998, KIT demonstrated the first photon production with a super-mini of 3.8 mm period length [1]. This s...
background: vhl (von hippel-lindau), runx-3 (runt-related transcription factor 3), e-cadherin (epithelial cadherin), p15 (ink4a, cyclin dependent kinase inhibitor), and p16 (ink4b) genes are essential in hematopoiesis. the aim of this study was to explore the correlation between gene expression and promoter methylation in cd34+ stem cells before and after differentiation to erythroid lineage. m...
Circulating cell-free DNA (cfDNA) is becoming an important clinical analyte for prenatal testing, cancer diagnosis and cancer monitoring. The extraction stage is critical in ensuring clinical sensitivity of analytical methods measuring minority nucleic acid fractions, such as foetal-derived sequences in predominantly maternal cfDNA. Consequently, quality controls are required for measurement of...

Four commercial DNA extraction kits and a minor modification in the DNA elution procedure were evaluated for the quantitation of bacteria in pig manure samples. The PowerSoil(®), PowerFecal(®), NucleoSpin(®) Soil kits and QIAamp(®) DNA Stool Mini kit were tested on raw manure samples and on lagoon effluents for their ability to quantify total bacteria and a subdominant bacteria specific of pig ...
