The aim of this work was to collect epidemiological information concerning the presence of Enteroaggregative Escherichia coli, stx-producing Escherichia coli and stx2a-converting bacteriophage, in ruminants faeces.

Evaluation and comparison of a developed PMA-qPCR Campylobacter enumeration method with the reference method, after exposure of the broiler rinse artificially contaminated with the bacteria to stress conditions.

We investigated the ability of quantitative real-time PCR, using plasmids calibrants, together with the triploid maize seed endosperm and the haploid pollen, to get good estimates for the copy number of a transgene in relation to the copy number of a species specific gene as a mean to distinguish between pollen and flour from maize.

Achieving selective and sensitive quantitation of double stranded DNA (dsDNA) using spectrophotometric methods can be problematic. Recognizing these difficulties, researchers have incorporated fluorescence-based quantitation techniques in their workflows to obtain the required sensitivity and target selectivity.

We have developed a new rapid bed-side assay system for in vitro diagnosis of infectious diseases, using “silver amplification method”, an application of photography-developing technology. The automatic analyzer brings results in fifteen minutes, enhancing sensitivity up to 1000 times compared to the conventional immunochromatography. We applied the technology for diagnosis of hospitalized children. The analyzer was useful for rapid and precise diagnosis of influenza A and B.

Most Next Generation Sequencing (NGS) library prep methods introduce sequence bias with the use of enzyme processing and fragmentation steps can introduce errors in the form of incorrect sequence and misrepresented copy number. With molecular indexed libraries, each molecule is tagged with a molecular index randomly chosen from ~10,000 combinations so that any two identical molecules become distinguishable (with odds of 10,000/1), and can be independently evaluated in later data analysis.

Whole-cell patch-clamp recording enables detecting electrophysiological signals from neurons, and RNA can be harvested into the patch pipette from the cells.We have optimized a dPCR protocol for determining exact transcript numbers in single neurons after patch-clamp recording by using dPCR based on high-density nanocapillary PCR.

Sucrose synthase (Ss) catalyzes the reversible conversion of sucrose and a nucleoside diphosphate into the corresponding nucleoside diphosphate-glucose and fructose being one of the main enzymes of carbohydrate metabolism. The objectives of this study were: to create a TILLING population in winter wheat; to identify new alleles of Ss1 gene; to compare relative expression of Ss1 in leaves and crowns of mutant versus wild type plants during cold acclimation.

Rice seeds loose germination capacity with ageing. Loses in genetic integrity was found to occur during artificial ageing at a time when percentage germination declined to 54%.
