[Results of the first All-Russian consensus conference on bariatric surgery].

Until now, there has not been organized consensus for standardization in bariatric surgery In Russia. We present the results of the first Bariatric Surgery Consensus Conference conducted in Barnaul (March, 2023). A list of questions was proposed within 6 blocks: 1) general issues of bariatric surgery, 2) sleeve gastrectomy, 3) one-anastomosis gastric bypass («mini-gastric bypass»), 4) Roux-en-Y Gastric Bypass, 5) Single Anastomosis Duodenal Switch and other options for biliopancreatic bypass, 6) rare procedures.

Eco-friendly TEMPO/laccase/O biocatalytic system for degradation of Indigo Carmine: operative conditions and laccase inactivation.

The biocatalytic system laccase/TEMPO/O has attracted the attention of researchers over the past two decades. A variety of applications for the system include organic synthesis, modification of cellulose, and oxidative degradation of environmental contaminants. A rigorous and predictable quantitative assessment of the change in enzymatic activity under the influence of a mediator is important for such a system.

Intramolecular hydrogen bonds of gossypol imine derivatives.

Evaluation of intramolecular hydrogen bond energies of twenty gossypol imine derivatives was carried out using H NMR spectroscopy and quantum chemistry methods. Gossypol imine derivatives contain various intramolecular hydrogen bonds: O-H⋯O, N-H⋯O, O-H⋯N, C-H⋯O and O-H⋯π. The existence of dienamine and diimine tautomeric forms causes some differences in the intramolecular hydrogen bonding of these compounds.

Cytological and molecular diagnosis of Hürthle cell thyroid tumors: Analysis of three cases.

The cytological diagnosis of Hürthle cell (oncocytic) thyroid tumors by means of fine-needle aspiration biopsy represents a challenge, as Hürthle cell polymorphism and atypia alone are not indications of malignancy. In our recent work, an original diagnostic algorithm was proposed, which identified and typed malignant thyroid tumors by analyzing the molecular markers of cytological preparations. The aim of the present study was to assess the effectiveness of this algorithm at detecting Hürthle cell thyroid tumors in clinical samples used for cytological examination.

Relay and complete synchronization in heterogeneous multiplex networks of chaotic maps.

We study relay and complete synchronization in a heterogeneous triplex network of discrete-time chaotic oscillators. A relay layer and two outer layers, which are not directly coupled but interact via the relay layer, represent rings of nonlocally coupled two-dimensional maps. We consider for the first time the case when the spatiotemporal dynamics of the relay layer is completely different from that of the outer layers.
