Mechanisms of stretch-induced electro-anatomical remodeling and atrial arrhythmogenesis.

Atrial fibrillation (AF) is the most common cardiac rhythm disorder, often occurring in the setting of atrial distension and elevated myocardialstretch. While various mechano-electrochemical signal transduction pathways have been linked to AF development and progression, the underlying molecular mechanisms remain poorly understood, hampering AF therapies. In this review, we describe different aspects of stretch-induced electro-anatomical remodeling as seen in animal models and in patients with AF.

[Robot-assisted radical prostatectomy in patients after transurethral resection of the prostate].

Performing a radical treatment of prostate cancer in patients with a history of transurethral resection of the prostate (TURP) is a serious task even for an experienced surgeon, due to the anatomical and topographic changes that occur after endoscopic surgery. The technical possibilities of robotic technologies have great potential for obtaining the best treatment results for this category of patients. In order to review the intra- and postoperative outcomes of robot-assisted radical prostatectomy (RARP) in patients with a history of PCa and TURP, we selected relevant publications in the PubMed and Google Scholar databases for the period from 2008 to 2022.

[Robot-assisted prostatectomy for PT3. Oncological and functional outcomes].

In 2020, prostate cancer (PCa) ranked third in the structure of the most significant oncological diseases. In the Russian Federation, in terms of the frequency of detection among men, prostate cancer is second only to tumors of the upper respiratory tract and lungs, accounting for 14.9%.

Caveolae-associated cAMP/Ca-mediated mechano-chemical signal transduction in mouse atrial myocytes.

Caveolae are tiny invaginations in the sarcolemma that buffer extra membrane and contribute to mechanical regulation of cellular function. While the role of caveolae in membrane mechanosensation has been studied predominantly in non-cardiomyocyte cells, caveolae contribution to cardiac mechanotransduction remains elusive. Here, we studied the role of caveolae in the regulation of Ca signaling in atrial cardiomyocytes.
