Mitral valve disease is common. regurgitation the second most frequent indication for surgery in Europe and despite decline of rheumatic fever Western societies, mitral stenosis any aetiology a regular finding all echo departments. is, therefore, one common pathologies encountered by echocardiographers, as both primary echocardiography secondary when investigating other cardiovascular processes...

As human activities expand into naturally or man-made radiation-prone environment, the need for radiation-hardened (Rad-Hard) electronic hardware surges. The state-of-the-art silicon-based and 2D materials-based Rad-Hard transistors can withstand up to 1 Mrad (Si) of total ionization dose (TID), while higher TID tolerance is being heatedly sought after. Here, few-layer MoS2 field-effect (FETs) ...

Abstract Product repairs are at the core of sustainable consumption and user manuals can play a relevant role in facilitating them. They accredited source product information for end users therefore sought as an important means diagnosis subsequent repair household appliances. However, despite increasing societal demand repairable products, few studies have been conducted on extent to which con...

Due to its avascular organization and low mitotic ability, articular cartilage possesses limited intrinsic regenerative capabilities. The aim of this study is achieve one-step repair in situ via combining bone marrow stem cells (BMSCs) with a xenogeneic Acellular dermal matrix (ADM) membrane. ADM membranes were harvested from Sprague-Dawley (SD) rats through standard decellularization procedure...

In the last decades, high priority has been given by research community to development of low-damage structures, and reparability become fundamental for minimizing environmental economic impact reconstruction. this context, European Research Fund Coal Steel (RFCS) project DISSIPABLE was carried out, with aim test large-scale structures where dissipation is concentrated on replaceable components...

Degenerative mitral valve (МV) disease is a common disorder affecting around 2% of the population (Enriquez-Sarano M et al., 2009). The most common ending in patients with degenerative valve disease is leaflet rolapsed due to elongation or rupture of the chordal apparatus, resulting in varying degrees of МV regurgitation due to leaflet malcoaptation during ventricular contraction. The emphasis ...

In rich scattering environments, wireless systems with multiple transmit and receive antennas (MIMO) offer large capacity gains. They are in general based on a parallel transmission of 1 ≤ M ≤ NT signal steams called layers (NT is the number of transmit antennas). If the channel is not known to the transmitter the best strategy would be to exploit transmit diversity for each layer. This ensures...

The sulfhydryl enzyme malate synthase was inactivated by X-irradiation in air-saturated aqueous solution, in the absence or presence of a variety of additives (thiols, antioxienzymes, typical radical scavengers, inorganic salts, buffer components, substrates, products, analogues). Radiation-induced changes of enzymic activity were registered immediately after stop of irradiation and in the post...
