An Amperometric Sensor with Anti-Fouling Properties for Indicating Xylazine Adulterant in Beverages.

Amperometric electrochemical sensing schemes, which are easily fabricated and can directly relate measured current with analyte concentrations, remain a promising strategy for the development of the portable, in situ detection of commonly employed adulterants. Xylazine (XYL) is a non-narcotic compound designed for veterinary use as a sedative known as Rompun. XYL is increasingly being abused as a recreational drug, as an opioid adulterant and, because of its chemical properties, has found unfortunate prominence as a date rape drug spiked into beverages.

Fouling-Resistant Voltammetric Xylazine Sensors for Detection of the Street Drug "Tranq".

As the opioid crisis continues to wreak havoc on a global scale, it is increasingly critical to develop methodologies to detect the most dangerous drugs such as fentanyl and its derivatives, which have orders of magnitude higher potency than morphine. The scientific challenge for chemical detection of fentanyl and its derivatives is complicated by both the constantly increasing synthetic variations of the drug as well as the expanded use of adulterants. One tragically consequential example is the nocuous street drug known as "Tranq", which combines fentanyl or a fentanyl derivative with the veterinary sedative Rompun, chemically identified as xylazine (XYL).

[The practice of stapes surgury in Russia].

The aim of this study - to investigate the practice of stapes surgery in Russia using a special questionnaire (Appendix 1). Thirty-three questionnaires were sent to specialists dealing with stapes surgery in various Russian medical institutions. Responses were received from all ENT specialists, of whom 75.

[DEFINITION OF WOMEN REPRODUCTIVE TRACT MICROFLORA COMPOSITION USING TEST-SYSTEM "FEMOFLOR-17"].

The data about composition of the vaginal microflora of women with use of the test system "Femoflor-17" was analyzed. Established that 92.7% of samples contained lactobacilli.

[Featuring pathogenicity factors in biofilm-forming and no-biofilm forming strains of Staphylococcus epidermidis].

A comparative study of the manifestation of pathogenicity factors: hemolytic, lipase, letsytinase activity and ability to adhere in 20 film-forming and 17 non-film-forming strains of S. epidermidis. Studying pathogenicity factors of the film-forming strains it was found that complete hemolysis and lipase activity shown was by all the film-forming strains of S.
