1961 SovietRxiv: ru-196101.22581

This paper addresses quantitative comparison of differential thermographic peak areas when substances or mixtures have different effective heat transfer coefficients. Building on a previously derived relation, the authors test a correction that reduces measured areas to a common heat transfer condit…

On Continuum Models of Control Systems

Corresponding Member of the Academy of Sciences of the USSR I. M. GELFAND and M. L. TSETLIN
1960 SovietRxiv: ru-196001.84894

The paper proposes a continual model of control systems intended to describe biological media more naturally than discrete automata or logical networks. It defines an active tissue whose points have instantaneous excitation, refractory time, phase-dependent propagation velocity, and possible spontan…

Destruction and formation of structures of natural proteins during their transfer through nonporous membranes

Academician V. A. KARGIN, P. V. KOZLOV, S. Ya. MIRLINA, and Z. A. KAPRALOVA
1960 SovietRxiv: ru-196001.76613

This study examines the destruction and reformation of natural protein structures during high-voltage electrodialysis through nonporous cellophane membranes. Using gelatin, myosin, denatured egg albumin, and edestin, the authors combine transfer experiments under varied temperature, concentration, v…

Interaction of $\mathrm{N}$-benzoyl-$\mathrm{O}$-(benzoyl-phenylalanyl-$\mathrm{C}^{14}$)-serine with ribonuclease

M. M. Botvinnik, A. P. Andreeva
1960 SovietRxiv: ru-196001.68079

The study examines the reaction of N-benzoyl-O-(benzoylphenylalanine-C14)-serine with ribonuclease, extending earlier work on transfer of labeled benzoylphenylalanine to proteins. Ribonuclease was incubated with the labeled O-peptide under varying peptide to protein ratios, with active, boiled, or a…

The influence of the solvent and specific nature of the addition of nucleotides upon the reduplication of DRA

Unknown
1960 SovietRxiv: ru-196001.65180

This paper develops a statistical mechanical model of DNA reduplication that extends an earlier treatment by including solvent interactions, specificity of nucleotide attachment, and flexibility of the free DNA chains. 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

V. V. Patrikeev, Academician A. A. Balandin, E. I. Klabunovskii,
1960 SovietRxiv: ru-196001.63069

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

N. N. SUVOROV, L. V. SOKOLOVA, V. M. RYZHKOVA, and D. M. ZAIKINA
1960 SovietRxiv: ru-196001.62994

This study examines the microbiological deacetylation of corticosteroid 21-acetates using a VNIKhFI-1 bacterial strain identified as belonging to the Bacillus megatherium group. Fermentation in a yeast extract and glucose medium converted cortisone acetate, prednisone acetate, Reichstein’s substance…

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

E. B. Burlakova and Corresponding Member of the Academy of Sciences of the USSR N. M. Emanuel’
1960 SovietRxiv: ru-196001.52690

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

Academician of the Academy of Sciences of the BSSR B. I. STEPANOV, A. I. SKRIGAN, A. M. SHISHKO
1960 SovietRxiv: ru-196001.43847

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

Academician I. L. KNUNYANTS, N. E. GOLUBEVA, and O. V. KILDISHEVA
1960 SovietRxiv: ru-196001.42541

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…

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

Unknown
1960 SovietRxiv: ru-196001.18804

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

M. V. VOL'KENSHTEIN and Al. M. ELYASHEVICH
1960 SovietRxiv: ru-196001.07244

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…

On Some Regularities of Solubilization in Protein Systems

Unknown
1958 SovietRxiv: ru-195801.49125

This study examines how the molecular state of gelatin in aqueous solution affects its ability to solubilize benzene, a sparingly water-soluble hydrocarbon. Purified gelatin solutions were investigated refractometrically over varying pH, concentration, and temperature, with viscosity measurements us…

Fundamentals of the Chemistry of Enzymes and Antimetabolites from the Perspective of Catalysis Theory

Academician A. A. BALANDIN
1957 SovietRxiv: ru-195701.34845

This paper applies multiplet catalysis theory to enzyme action and antimetabolism, arguing that enzymatic specificity can be interpreted through reacting “index” groups and the structural effects of non-index substituents. It classifies enzyme types by their reaction indices, relates substituent eff…
