Using Agaricus bisporus crude extract in distance based 3D microfluidic paper-based analytical device and spectrophotometric analytical procedures for thiols determination.

Novel and simple spectrophotometric and distance based procedures for thiols (L-cysteine, N-acetylcysteine, and glutathione) determination in biological fluids and pharmaceuticals have been proposed based on their inhibitory action on the oxidation of catechol in the presence of Agaricus bisporus crude extract (ABE). The influence of L-glycine, L-alanine, L-proline, L-methionine, L-cystine, ascorbic acid, uric acid, and bilirubin on the thiol determination has been investigated. Uric acid, bilirubin, L-cystine (oxidized thiol), and L-amino acids do not interfere with the determination.

[The study of the effect of mono- and polymalt extracts on the psycho-physiological functions of outbred rats in an experiment with course consumption].

The search for natural ingredients that have a certain nutritional value and contribute to the preservation of human health is a very urgent task. of this research was to study the effect of three viscous extracts - two polymalt and one malt extract, on the psychophysiological functions of animals in an experiment with prolonged consumption. .

The experience of using a mineral chelate additive for growing juveniles of the African sharptooth catfish (Clarias Gariepinus) in a recirculating aquaculture system.

Growing fish in a recirculating aquaculture system (RAS) involves various stress factors that directly affect their physiological condition. This study aimed to investigate the effect of a chelated organic-mineral additive including Fe, Mn, Cu, Zn, Co, Se and I; on the rearing performance of juvenilecatfish (Clariasgariepinus) under RAS conditions. Four groups of fish (n=50) were formed: a control group (receiving standard feed) and three experimental groups (receiving standard feed with biogenic elements chelate compounds in different concentrations).

Evaluation of Age-Dependent Changes in the Coloration of Male Killifish Nothobranchius Guentheri Using New Photoprocessing Methods.

Fish as model objects have found wide applications in biology and fundamental medicine and allow studies of behavioral and physiological responses to various environmental factors. Representatives of the genus are one of the most convenient objects for such studies. Male fish belonging to the family are characterized by extremely diverse coloration, which constantly changes, depending on the age of the fish, environmental factors, and social hierarchical status.
