Bilateral Dolichoarteriopathies of the Internal Carotid Artery: Surgical Treatment and Results.

The approach to surgical treatment of symptomatic bilateral dolichoarteriopathies of the internal carotid artery (DICA) remains an unresolved problem today. The aim of this article is to compare the methods of reconstruction of the stage-by-stage surgical treatment of bilateral DICA, depending on the type of deformity. The study included 30 patients with clinical manifestations of cerebrovascular insufficiency (CVI), who were found to have hemodynamically significant bilateral DICA.

Electrolysis as a Universal Approach for Isolation of Diverse Chitin Scaffolds from Selected Marine Demosponges.

Three-dimensional chitinous scaffolds often used in regenerative medicine, tissue engineering, biomimetics and technology are mostly isolated from marine organisms, such as marine sponges (Porifera). In this work, we report the results of the electrochemical isolation of the ready to use chitinous matrices from three species of verongiid demosponges (, and ) as a perfect example of possible morphological and chemical dimorphism in the case of the marine chitin sources. The electrolysis of concentrated NaSO aqueous solution showed its superiority over the chemical chitin isolation method in terms of the treatment time reduction: only 5.

A laparoscopic one anastomosis gastric bypass with wrapping versus nonwrapping fundus of the excluded part of the stomach to treat obese patients (FundoRingOAGB trial): study protocol for a randomized controlled trial.

Background: Laparoscopic one anastomosis gastric bypass (LOAGB) is a simple variation of gastric bypass and has gained worldwide popularity with clinical outcomes similar to laparoscopic Roux-en-Y gastric bypass (LRYGB) for weight loss and management of comorbidities. However, biliary reflux to the esophagus negates the benefits of LOAGB. In addition, weight gain after LOAGB and after LRYGB is a major problem in bariatric surgery.

Calcite Nanotuned Chitinous Skeletons of Giant Marine Demosponge.

Marine sponges were among the first multicellular organisms on our planet and have survived to this day thanks to their unique mechanisms of chemical defense and the specific design of their skeletons, which have been optimized over millions of years of evolution to effectively inhabit the aquatic environment. In this work, we carried out studies to elucidate the nature and nanostructural organization of three-dimensional skeletal microfibers of the giant marine demosponge , the body of which is a micro-reticular, durable structure that determines the ideal filtration function of this organism. For the first time, using the battery of analytical tools including three-dimensional micro-X-ray Fluorescence (3D-µXRF), X-ray diffraction (XRD), infra-red (FTIR), Raman and Near Edge X-ray Fine Structure (NEXAFS) spectroscopy, we have shown that biomineral calcite is responsible for nano-tuning the skeletal fibers of this sponge species.

Stapleless vs Stapled Gastric Bypass vs Hypocaloric Diet: a Three-Arm Randomized Controlled Trial of Body Mass Evolution with Secondary Outcomes for Telomere Length and Metabolic Syndrome Changes.

Background: Obesity and metabolic syndrome (MetS) reduce life expectancy and are challenging to resolve. This randomized controlled trial (RCT) of patients with obesity and MetS undergoing surgical vs nonsurgical treatment compared changes in BMI, and secondarily, telomere length (as a biomarker of life expectancy) and changes in MetS components (insulin resistance, dyslipidemia, hypertension).

Methods: Study design was a single-center, prospective, three-arm RCT.
