Extracts from Four Species of Xylotrophic Basidiomycetes Growing in the Middle Urals (Russia) Revealed Cytotoxic Effects on Model Object Drosophila melanogaster.

In our study, four species of wood-decaying fungi with perennial fruiting bodies were used as the source of biologically active compounds (BACs) - Inonotus obliquus (chaga), Fomitopsis pinicola, Fomes fomentarius, and Ganoderma applanatum. Fungi have a wide range of secondary metabolites but are used much less frequently than plants in both folk and official medicine. Fungotherapy could be considered a promising trend in the development of modern natural therapy.

Mast Cells as a Component of Spermatogonial Stem Cells' Microenvironment.

The formation of mature spermatozoa originates from spermatogonial stem cells (SSCs) located near the basement membrane of the seminiferous tubules. This developmental process, known as spermatogenesis, is tightly regulated to ensure continuous sperm production. A critical aspect of this regulation is the balance between SSC differentiation and self-renewal, which is directed by various factors guiding SSCs in either of these two directions.

The Gypsum Influence on the Formation of Secondary Phases During Autoclave Leaching of Gold-Bearing Concentrates and the Silver Recovery Using Cyanidation.

Autoclave leaching of sulfide concentrates may produce various ferric secondary phases, depending on the arsenic content and temperature. Silver is converted to argentojarosite, from which it is not recoverable by standard cyanidation methods. To increase silver recovery, it is necessary to reduce the argentojarosite formation during autoclave leaching.

Facile One-Pot Conversion of (poly)phenols to Diverse (hetero)aryl Compounds by Suzuki Coupling Reaction: A Modified Approach for the Synthesis of Coumarin- and Equol-Based Compounds as Potential Antioxidants.

A series of 16 (hetero)aryl compounds based on coumarin and equol has been efficiently synthesized by exploring the palladium-catalyzed Suzuki cross-coupling reactions. Polyphenol based on coumarin (4-methyl-7-hydroxy coumarin) was initially converted to corresponding coumarin imidazylate and then subjected to Suzuki coupling reaction with 4-methoxyphenylboronic acid to obtain the coupled product. This modified approach was later developed into a one-pot methodology by directly reacting the polyphenol with 1,1-sulfonyldiimidazole (SDI) and boronic acid in situ to obtain the Suzuki coupled product in one step.

Unraveling the Liver-Brain Axis: Resveratrol's Modulation of Key Enzymes in Stress-Related Anxiety.

Stress-related anxiety disorders and anxiety-like behavior in post-traumatic stress disorder (PTSD) are associated with altered neurocircuitry pathways, neurotransmitter systems, and the activities of monoamine and glucocorticoid-metabolizing enzymes. Resveratrol, a natural polyphenol, is recognized for its antioxidant, anti-inflammatory, and antipsychiatric properties. Previous studies suggest that resveratrol reduces anxiety-like behavior in animal PTSD models by downregulating key enzymes such as 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD-1) and monoamine oxidases (MAOs).

Potentiometry in determining the antioxidant capacity of compounds of different hydrophilicity in the joint presence using mixed solvents and surfactants.

In this work, for the first time, the potentiometric method was used to determine the antioxidant capacity (AOC) of compounds of different hydrophilicity in the joint presence using mixed solvents and surfactants. The AOC of model solutions of antioxidants of different hydrophilicity was determined separately and in the joint presence in the media of phosphate buffer-surfactant and mixed solvents-surfactant, using as an example the ascorbic acid and the α-tocopherol. It was shown that the surfactant Triton X-100 is able to solubilize α-tocopherol under the selected conditions, allows to obtain reproducible and accurate results, and has less effect on the equilibrium rate of the K[Fe(CN)]/K[Fe(CN)] system.
