Since the introduction of the sutureless Perceval® (Sorin Group, Saluggia, Italy) in Europe after CE mark in 2012, the "sutureless approach" is becoming more and more popular. Sutureless implantation in general is easy, fast and safe, but bears several potential pitfalls. This might result in inferior functional results affecting also clinical outcomes. In our center, more than 300 implant procedures have been performed up to date by mainly two senior surgeons. The technique is in the process of spreading to all surgeons performing aortic valve procedures...

The mechanical characteristics of the ankle such as its kinematics and load transfer properties are influenced by the geometry of the articulating surfaces. A recent, image-based study found that these surfaces can be approximated by a saddle-shaped, skewed, truncated cone with its apex oriented laterally. The goal of this study was to establish a reliable experimental technique to study the relationship between the geometry of the articular surfaces of the ankle and its mobility and stability characteristics and to use this technique to determine if morphological approximations of the ankle surfaces based on recent discoveries, produce close to normal behavior...

BACKGROUND: Aortic valve replacement (AVR) with a sutureless valve is an innovative therapy in high-risk elderly patients. The study aim was to compare the early results of AVR using sutureless aortic valves or stentless aortic bioprostheses. METHODS: A retrospective analysis was conducted of 55 patients who underwent AVR with either a sutureless valve (Perceval S; n = 24 or Edwards Intuity; n = 9) or a stentless valve (Sorin Freedom SOLO™; n = 22). RESULTS: Baseline patient characteristics were similar in both groups, except for NYHA class...

An anomalous origin of the left circumflex coronary artery (LCx) from the right sinus of Valsalva is a frequent coronary problem. This particular condition, though usually silent, is associated with an increased incidence of serious complications during surgical aortic valve replacement (AVR) and transcatheter aortic valve implantation. Here, the cases are described of four patients with an anomalous origin of the LCx from the right sinus of Valsalva who underwent sutureless AVR with the Sorin Perceval S prosthesis...

Using plasma in conjunction with fluorinated compounds is widely encountered in material processing. We discuss several plasma techniques for surface fluorination: deposition of fluorocarbon thin films either by magnetron sputtering of polytetrafluoroethylene targets, or by plasma-assisted chemical vapor deposition using tetrafluoroethane as a precursor, and modification of carbon nanowalls by plasma treatment in a sulphur hexafluoride environment. We showed that conformal fluorinated thin films can be obtained and, according to the initial surface properties, superhydrophobic surfaces can be achieved...

Liver fibrosis scoring by liver biopsy has become a rarity in daily practice mainly because many non-invasive methods with similar accuracy have been developed. Among all ultrasound elastography imaging methods, Strain Elastography (SE) is the most widely available. Although SE is a qualitative and semi-quantitative method, there is reliable applicability for liver fibrosis estimation and multiple ways to transform SE into a quantitative method, in order to obtain a fibrosis score. The aim of this review is to briefly introduce all these methods and to offer support in choosing the best estimation method for liver fibrosis, with SE...

Bacteriophages (phages) or bacterial viruses have long been proposed as an alternative therapy against antibiotic-resistant bacteria such as Escherichia coli Even though poorly documented in the scientific literature, a long clinical history of phage therapy in countries such as Russia and Georgia suggests potential value in the use of phages as antibacterial agents. Escherichia coli is responsible for a wide range of diseases, intestinal (diarrhoea) and extraintestinal (UTI, septicaemia, pneumoniae, meningitis), making it an ideal target for phage therapy...
