is a complex of anaerobic bacteria responsible for the epidemics of post-antibiotic diarrhea as one of the examples of CDI ( infection). As many as 70% of cases concern hospitalized patients, particularly those in intensive care units. Ribotyping is one of the most common methods for differentiating bacterial strains. The purpose of this work was to show the effectiveness of the gel electrophoresis-based PCR ribotyping method and the Webribo database for typing isolates, including the hypervirulent 027 ribotype. DNA samples extracted from 69 strains with previously marked genotypes were included in this study. PCR was performed using 16S-23S primers, and capillary gel electrophoresis was performed on the Applied Biosystem 3130xl Genetic Analyzer. The Webribo database was applied for ribotype assignment. Out of 69 samples, 48 belonged to already known ribotypes, 13 represented new ribotypes and 8 was indicated as similar to the existing ones, having some differences. Capillary gel electrophoresis-based PCR is an effective method for the differentiation of ribotypes and can be recognized as a very useful tool in epidemiological studies, while the Webribo database is a useful and an accessible database for a quick analysis of ribotypes.

Driven by public demand, new safe and effective approaches for achieving dermal rejuvenation are continuously being developed. Recently, there has been growing interest and advances in carbon dioxide therapy, or carboxytherapy. Based on the Bohr effect, carboxytherapy enhances the release of O from the blood into the surrounding tissues in response to increased blood CO.

Sodium dodecyl sulfate capillary gel electrophoresis (SDS-CGE) is a frequently used analytical technique in size-based separation of proteins, playing a vital role in the biopharmaceutical industry for the analysis and characterization of therapeutic proteins, employing both UV and fluorescent detection. Understanding the effect of the operational parameters using easily applicable in migratio fluorescent labeling is increasingly critical, especially because multicapillary electrophoresis systems with fluorescent detection have recently gained prominence in high-throughput biopolymer analysis. In this study, the effects of the three most important user-adjustable operational parameters (temperature, gel concentration, and electric field strength) were investigated on the electrophoretic mobility and resolution of SDS-protein complexes in the presence of propidium iodide in the gel-buffer system.

Capillary electrophoresis-sodium dodecyl sulfate (CE-SDS) is widely used in the biopharmaceutical industry for monitoring purity and analyzing impurities. The accuracy of the method may be compromised by artificial species resulting from sample preparation or electrophoresis separation due to suboptimal conditions. During non-reduced CE-SDS analysis of a multispecific antibody (msAb), named as multispecific antibody C (msAb-C), a cluster of unexpected peaks was observed after the main peak.

Dominantly inherited intronic GAA repeat expansions in the fibroblast growth factor 14 gene have recently been shown to cause spinocerebellar ataxia 27B. Currently, the pathogenic threshold of (GAA) repeat units is considered highly penetrant, while (GAA) is likely pathogenic with reduced penetrance. This study investigated the frequency of the GAA repeat expansion and the phenotypic profile in a Cypriot cohort with unresolved late-onset cerebellar ataxia.

Characterizing major bovine milk proteins, including whey and casein, is of significant interest in the dairy industry. The diverse array of protein proteoforms can be different in terms of genetic variation, breed ways, lactation stage, and animal nutritional status. Current routine methods for bovine milk protein profiling are typically based on immunological techniques, infrared spectroscopy, slab gel isoelectric focusing, capillary electrophoresis, and high-performance liquid chromatography.
