Influence of the Structure of Hydrothermal-Synthesized TiO Nanowires Formed by Annealing on the Photocatalytic Reduction of CO in HO Vapor.

The present study investigates the photocatalytic properties of hydrothermally synthesized TiO nanowires (NWs) for CO reduction in HO vapor. It has been demonstrated that TiO NWs, thermally treated at 500-700 °C, demonstrate an almost tenfold higher yield of products compared to the known commercial powder TiO P25. It has been found that the best material is a combination of anatase, TiO-B and rutile.

[Physicians' Adherence to Clinical Guidelines on the Chronic Heart Failure Diagnosis and Treatment: Changes Over 2 Years of the Document's Existence].

Aim: To study how physicians' commitment to the basic provisions of clinical guidelines (CGs) for the diagnosis and treatment of chronic heart failure (CHF) has changed over the two years of the document existence.

Material And Methods: An anonymous survey was performed for 263 physicians (204 cardiologists, 46 internists and 13 other specialists) who were trained in advanced training programs in 2022. The questionnaire included questions regarding self-assessment of the respondents' professional knowledge, their attitude to the role of CGs in everyday practice and ideas about methods for treatment of CHF.

The Composite TiO-CuO Layers Formed by Electrophoretic Method for CO Gas Photoreduction.

This study demonstrates the ability to control the properties of TiO-CuO composite layers for photocatalytic applications by using a simple electrophoretic deposition method from isopropanol-based suspension. To obtain uniform layers with a controlled composition, the surfactant sodium lauryl sulfate was used, which influenced the electrophoretic mobility of the particles and the morphology of the deposited layers. The TiO-CuO composite layers with different CuO contents (1.

[Physicians' adherence to the guidelines on the chronic heart failure diagnosis and treatment].

Aim      To evaluate the physician's knowledge of basic provisions of clinical guidelines for diagnosis and treatment of chronic heart failure (CHF) and to determine how the actions of physicians in their everyday clinical practice comply with these provisions.Materials and methods The study analyzed anonymous questionnaires of 185 physicians (127 cardiologists, 40 internists and general practitioners, 18 other specialists) who were trained in advanced training programs during the 2020/2021 academic year. The main part of the questionnaire included 15 questions related to the classification, diagnosis, pharmacotherapy, and the use of implantable devices in the treatment of patients with CHF.

Peptide-protein complex from cattle sclera: Structural aspects and chaperone activity.

The influence of temperature and chaotropic agents on the spatial organization of the peptide-protein complex isolated from cattle sclera at the level of secondary structure was studied by UV, CD spectroscopy, and dynamic light scattering. It is shown that this complex has high conformational thermostability. The point of conformational thermal transition (65 °C) was determined, after which the peptide-protein complex passes into a denatured stable state.
