Background: One of the major aspects of traceability in food authenticity assessment is to explore practical methods to find the origin of food. Objective: The aim of the present study was to find a DNA based method for authentication and traceability of food, which are of great importance in health management. Methods: Four different DNA extraction methods were applied to obtain high pure DNA...

Genome editing is a set of techniques for introducing targeted changes in genomes. It may be achieved by enzymes collectively called site-directed nucleases (SDN). Site-specificity SDNs provided either the DNA binding domain protein molecule itself or RNA molecule(s) that direct SDN to specific site genome. In contrast transgenesis resulting insertion exogenous DNA, genome only affects endogeno...

Herein, a monolithic polycarbonate (PC) microdevice was developed to handle both DNA extraction and polymerase chain reaction (PCR) processes successively. Target cell – Cochlodinium polykrikoides microalgae, the causative species for harmful algal blooms in South Korea – was firstly captured on amine-functionalized microbeads via electrostatic interaction and then lysed to release DNA into sub...

aspartic proteases are a relatively small group of enzymes which express in various nematodes including onchocerca volvulus. an estimation of the gene copy number corresponding to the ov7a clone, which contains a cdna insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of o. volvulus, was made by slot blot analysis in a closely related species o. gibsonig...

The multiple displacement amplification method has revolutionized genomic studies of uncultured bacteria, where the extraction of pure DNA in sufficient quantity for next-generation sequencing is challenging. However, the method is problematic in that it amplifies the target DNA unevenly, induces the formation of chimeric reads and also amplifies contaminating DNA. Here, we have tested the repr...

PURPOSE Speed of bloodstream infection diagnosis is vital to reduce morbidity and mortality. Whole genome sequencing (WGS) performed directly from liquid blood culture could provide single-assay species and antibiotic susceptibility prediction; however, high inhibitor and human cell/DNA concentrations limit pathogen recovery. We develop a method for the preparation of bacterial DNA for WGS-base...

Many viruses subvert the host cell's ability to mount and complete various DNA damage responses (DDRs) after infection. HCMV infection of permissive fibroblasts activates host DDRs at the time of viral deposition and during replication, but the DDRs remain uncompleted without arrest or apoptosis. We believe this was in part due to partitioning of the damage response and double strand break repa...
