The authors formulate the partition function for a partially separated double hel…

Selectivity of an Adsorbent Formed in the Presence of Bacteria toward Optical Isomers

This study examines whether silica gel formed in the presence of dissymmetric bacterial cultures can acquire optical selectivity toward enantiomers. Silicic acid gels were inoculated with right and left forms of Bacillus mycoides, then dried, oxidatively cleaned, and compared with a control silica g…

Microbiological deacetylation of corticosteroid 21-acetates

This study examines the microbiological deacetylation of corticosteroid 21-acetates using a VNIKhFI-1 bacterial strain identified as belonging to the Bacillus megatherium group.

Specific Features of the Action of Mercamine and Inhibitors of Radical-Chain Processes in Reactions Modeling Lipid Oxidation

This study examines the action of mercamine and hydroquinone on methyl oleate oxidation as a model for lipid oxidative processes associated with radiation injury. By comparing peroxide and oxide accumulation during oxidation, including additions before reaction onset and after peroxide buildup, the …

On the Association of Cellulose with Its Accompanying Substances in Plant Tissue

This paper examines whether cellulose in plant tissue is merely mechanically associated with lignin and other components or is partly chemically bound to them. The authors cooked pine woods of different ages, flax-fiber waste, and cotton cellulose in sodium deuteroxide prepared in heavy water, measu…

Targeted cancerolytic peptides

This paper addresses the limited specificity and toxicity of existing mutagenic antitumor agents by proposing short peptides as carriers capable of more selective interaction with DNA in cancer cells. The authors synthesize a series of tri- and tetrapeptide derivatives bearing di-(2-chloroethyl)amin…

Interaction of N-Benzoyl-(O-Benzoylphenylalanyl-C¹⁴)-Serine with Proteins

This study examines whether aminoacyl residues can be transferred from O-peptides of beta-hydroxyamino acids to proteins under enzymatic conditions. N-benzoyl-(O-benzoylphenylalanyl-C14)-serine was synthesized and incubated with insulin or blood-serum albumin in phosphate buffer, with chymotrypsin, …

Corrections to the Article Classification of Phosphorites (Doklady Akademii Nauk, vol. 128, no. 6, 1959)

Within experimental morphology, this paper examines extremity regeneration in anuran amphibians in relation to treatment with tissue extract. It addresses the broader problem of whether substances obtained from tissues can stimulate regenerative processes in limbs, a question relevant to understandi…

Model Thermodynamic Theory of Deoxyribonucleic Acid Polycondensation

This paper develops a model thermodynamic theory of DNA reduplication treated as polycondensation of nucleotide triphosphates with release of inorganic pyrophosphate, modifying earlier polymerization-based models. Using statistical-mechanical free energy expressions, the authors argue that reduplica…
