A single-tube method, ligation-mediated real-time PCR high-resolution melt analysis (LMqPCR HRMA), was modified for the rapid typing of Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. (ESKAPE) pathogens. A 97% agreement (60/62 isolates) was achieved in comparison to pulsed-field gel electrophoresis (PFGE) results, which indicates that LMqPCR HRMA is a rapid and accurate screening tool for monitoring nosocomial outbreaks.

With an increasing number of gene therapy clinical trials and drugs reaching the market, it becomes important to standardize the methods that evaluate the efficacy and safety of gene therapy. We herein report the generation of lentiviral standards which are stable, cloned human cells prepared from the diploid HCT116 cell line and which carry a known number of lentiviral vector copies in their genome. These clones can be used as reference cellular materials for the calibration or qualification of analytical methods that quantify vector copy numbers in cells (VCN) or lentiviral vector genomic integration sites (IS).

Background: Understanding how transcription occurs requires the integration of genome-wide and locus-specific information gleaned from robust technologies. Chromatin immunoprecipitation (ChIP) is a staple in gene expression studies, and while genome-wide methods are available, high-throughput approaches to analyze defined regions are lacking.
Results: Here, we present carbon copy-ChIP (2C-ChIP), a versatile, inexpensive, and high-throughput technique to quantitatively measure the abundance of DNA sequences in ChIP samples.

Rolling circle amplification (RCA) is an elegant and well-recognized isothermal nucleic acid amplification mechanism that has been widely used for the detection of various kinds of genetic biomarkers. However, traditional RCA is a linear signal amplifying mechanism so that the amplification efficiency is generally not satisfactory. Herein, we rationally combine RCA with efficient loop-mediated isothermal amplification (LAMP) to establish a rapid and ultrasensitive RCA-LAMP method for the detection of microRNAs (miRNAs).

The molecular mechanisms involved in myogenic differentiation are relatively well-known. Myogenic differentiation is regulated by the sequential activation of the basic helix-loop-helix myogenic regulatory transcription factors (MRFs), and biomechanical signals play an important role in the regulation of myogenesis. In this study, we sought to determine whether simulated microgravity culture using Gravite may affect myoblast differentiation and expression of MRF genes.
