Heterosexual couples dealing with infertility can seek Assisted Reproductive Technology (ART) treatments to achieve pregnancy. Within these programs, infertile couples can experience Recurrent Implantation Failure (RIF), which is the failure to achieve a ... see more

The paper presents the results of mathematical treatment of the luminescent spectra of ZnSe nanocrystals. The samples were formed by the implantation of 150 keV Zn+ and 170 keV Se+ ions in silicon dioxide layer obtained by oxidation of a silicon substrate... see more

Background: Transcatheter aortic valve implantation (TAVI) has become a standard of care for the treatment of symptomatic aortic stenosis in the elderly. The aim of the present study is to describe initial results in the international cardiovascular centr... see more

Introduction. Over the past decades, an increase in mortality from chronic heart failure has been recorded, for the treatment of which the implantation of a pacemaker can be used. The implanted pacemaker expands the possibilities of drug therapy, but requ... see more

The application of positron annihilation spectroscopy for the studies of defects produced by different types of charged particles and ions in a variety of materials is discussed with specific examples. The ability to detect and quantify the information th... see more

By increasing the Sn concentration in Ge1-ySny and Ge1-x-ySixSny systems, these materials can be tuned from indirect to direct bandgap along with increasing electronic and photonic properties. Efforts have been made to synthesize Sn-Ge and Ge-Si-Sn struct... see more

More than 50% of pregnant women after the programs of assisted reproductive technologies (ART) face the problem of recurrent miscarriage (RMC), especially in the first trimester. Significant role in the development of RMC has infectious factor and chronic... see more

A widespread introduction of modern alloplastic materials into the surgical practice has significantly improved the results of surgical treatment of the patients with ventral and postoperative ventral hernia. However, the implantation of synthetic materia... see more

Generation of metal plasma in vacuum arc discharge is always accompanied by a production of macroparticles (MPs). The MP contamination in coatings is the most important technological problem in plasma immersion ion implantation (PIII). For the case of PII... see more
