Biological microorganisms swim with flagella and cilia that execute nonreciprocal motions for low Reynolds number (Re) propulsion in viscous fluids. This symmetry requirement is a consequence of Purcell's scallop theorem, which complicates the actuation scheme needed by microswimmers. However, most biomedically important fluids are non-Newtonian where the scallop theorem no longer holds. It sho...

Bacterial contamination of injectable stored biological fluids such as blood plasma and platelet concentrates preserved in plasma at room temperature is a major health risk. Current pathogen reduction technologies (PRT) rely on the use of chemicals and/or ultraviolet light, which affects product quality and can be associated with adverse events in recipients. 405 nm violet-blue light is antibac...

AIM To develop a new, simple, and cheap method for estimating antioxidant activity in human fluids. METHODS The assay measured the capacity of the biological fluids to inhibit the production of thiobarbituric acid reactive substances (TBARS) from sodium benzoate under the influence of the free oxygen radicals derived from Fenton's reaction. A solution of 1 mmol/litre uric acid was used as sta...

Circulating nucleic acids (CNAs) are defined as RNA and DNA that are detected in biological fluids devoid of cellular material [1]. Free CNAs in the bloodstream have the potential to serve as biomarkers for certain cancers and disease states [2]. Free circulating RNA and exosomal RNA in the plasma and serum are generally present as short fragments ranging from 22 to 1000 nt [3]. The exosomes, w...

Forensic drug analysis involves qualitative and quantitative analysis of drugs of abuse and their metabolites in various complex biological matrices such as biological fluids and seized materials. Drugs of abuse such as opioids, cannabinoids, cocaine, amphetamines, hallucinogens and benzodiazepines are generally analyzed in biological fluids e.g. urine and plasma. While urine is efficient for i...

The article is devoted to the results of studies on development thin–layer chromatography (TLC) and UV–spectrophotometry analysis methods introduction ketamine determination substance extracted from composition biological fluids. developed during research were applied fluids positive obtained.

Covalently closed circular RNA molecules (circRNAs) have recently emerged as a class of RNA isoforms with widespread and tissue specific expression across animals, oftentimes independent of the corresponding linear mRNAs. circRNAs are remarkably stable and sometimes highly expressed molecules. Here, we sequenced RNA in human peripheral whole blood to determine the potential of circRNAs as bioma...
