Nowadays, the Internet of Things (IOT), electronics, and neural interfaces are becoming an integral part of our life. These technologies place unprecedentedly high demands on materials in terms of their mechanical and electrical properties. There are several strategies for forming conductive layers in such composites, e.

Materials And Methods: 901 patients, whose documents were sent to Chazov National Medical Research Center of Cardiology from regional medical and prophylactic institutions, were screened as selection for LVAD implantation. Firstly, all patients underwent transthoracic echocardiography performed according to the extended protocol with a comprehensive assessment of the left and right ventricle size and function.

- The study aimed to identify predictors of adverse cardiovascular events following edge-to-edge transcatheter mitral valve repair (TMVR) in patients with severe mitral regurgitation (MR), focusing on heart structure and function changes over time.
- It involved 73 high surgical risk patients (average age 71) who underwent TMVR, measuring various heart metrics before, shortly after, and one year post-procedure, including myocardial function and NT-proBNP levels.
- Results showed a significant reduction in MR in both primary and secondary categories within 12 months, alongside changes in heart chamber size and improvements in certain functional metrics, despite initial impairments in left ventricular function right after surgery.
Copolymers based on vinylidene fluoride are potential materials for ferroelectric memory elements. The trend in studies showing that a decrease in the degree of crystallinity can lead to an unexpected increase in the electric breakdown field is noted. An analysis of the literature data reveals that in fluorine-containing ferroelectric polymers, when using a bipolar triangular field, the hysteresis loop has an unclosed shape, with each subsequent loop being accompanied by a decrease in the dielectric response.
