oDays High-performance liquid chromatography (HPLC) for analysis of phospholipids has traditionally employed ultraviolet detection of the eluted compounds. The evaporative laser light-scattering detector (ELSD) offers new opportunities for quantitative analysis of lipids. Phospholipids were isolated from crude and degummed oils prepared from soyheans subjected to storage at high moisture conten...

BACKGROUND In-hospital hypovitaminosis C is highly prevalent but almost completely unrecognized. Medical awareness of this potentially important disorder is hindered by the inability of most hospital laboratories to determine plasma vitamin C concentrations. The availability of a simple, reliable method for analyzing plasma vitamin C could increase opportunities for routine plasma vitamin C ana...

In order to establish an effective and quick method for screening potential bioactive compounds in Traditional Chinese Medicines (TCMs), hepatocytes were employed for extracting either bifendate, a clinical medicine for liver diseases, or chemicals in Herba Artemisiae Scopariae (A. Scopariae), a commonly used traditional Chinese medicine for remedying liver diseases such as hepatitis induced by...

A poly(methyl red) film-modified glassy carbon electrode (PMRE) was fabricated for determination of norfloxacin (NFX). The electrochemical behavior of NFX was investigated and a well-defined oxidation peak with high sensitivity was observed at the film electrode. PMRE greatly enhanced the oxidation peak current of NFX owing to the extraordinary properties of poly(methyl red) film. Based on this...

A multi-wall carbon nanotubes (MWCNTs) composite with Nafion was modified on a glass carbon electrode. The modified electrode was then used as a voltammetric sensor in detecting 2,4,6-triaminopyrimidine (TAP). The surface morphology of the Nafion/MWCNTs composite film was characterized by atomic force microscopy (AFM), and the electrochemical behavior of TAP at this sensor was investigated in d...

The theory of gravitational structure formation in astrophysics and cosmology is revised based on real fluid behavior and turbulent mixing theory. Gibson's 1996-1998 theory balances fluid mechanical forces with gravitational forces and density diffusivity with gravitational diffusivity at critical viscous, turbulent, magnetic, and diffusion length scales termed Schwarz scales LSX. Condensation ...

Aim. Improve the results of treatment patients with decompensated forms chronic venous insufficiency by determining main hypertension inherent in varicose veins and postthrombotic syndrome.
 Materials methods. From 2018 to 2022, 147 (CVI) C6 according CEAP, aged from 38 69 years (on average, 55±5.3 years), were treated surgical clinic Communal non-commercial enterprise «Transcarpathian Reg...
