Potential Applications of Rare Earth Metal Nanoparticles in Biomedicine.

In recent years, the world scientific community has shown increasing interest in rare earth metals in general and their nanoparticles in particular. Medicine and pharmaceuticals are no exception in this matter. In this review, we have considered the main opportunities and potential applications of rare earth metal (gadolinium, europium, ytterbium, holmium, lutetium, dysprosium, erbium, terbium, thulium, scandium, yttrium, lanthanum, europium, neodymium, promethium, samarium, praseodymium, cerium) nanoparticles in biomedicine, with data ranging from single reports of effects found in vitro to numerous independent in vivo studies, as well as a number of challenges to their potential for wider application.

The Diagnostic and Prognostic Roles Played by Homocysteine and Other Aminothiols in Patients with Chronic Kidney Disease.

We examined standard clinical and laboratory biochemical parameters, as well as the levels of aminothiols in the blood and urine (homocysteine (Hcy), cysteine (Cys), S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH)) via capillary electrophoresis in patients with CKD at stages II-V. Patient outcomes were assessed after five years. To complete forecasting, correlation and ROC analysis were performed.

The Effect of Few-Layer Graphene on the Complex of Hardness, Strength, and Thermo Physical Properties of Polymer Composite Materials Produced by Digital Light Processing (DLP) 3D Printing.

The results of studying the effect of particles of few-layer graphene (FLG) synthesized by self-propagating high-temperature synthesis (SHS) on the complex of strength and thermo physical properties of polymer composite products obtained by digital light processing (DLP) 3D printing are presented. It was discovered to achieve an increase in thermophysical and strength parameters of polymers modified by FLG compared with samples made on the unmodified base resin. This result was achieved due to low defectiveness, namely the absence of Stone-Wales defects in the structure of FLG due to the homogeneous distribution of FLG over the volume of the polymer in the form of highly dispersed aggregates.

Non-contact navigated laser retinopexy for peripheral retinal tears and rhegmatogenous degenerations: first experience.

Purpose: To evaluate the first outcomes of non-contact navigated laser retinopexy for peripheral tears and rhegmatogenous degenerations of the retina.

Material And Methods: This prospective single-center interventional pilot study included 58 patients (68 eyes), among which 19 males and 39 females aged 47.5±16.

[On stomatological service in the Voronezh Oblast].

The article considers characteristics of organization of dental care for adult and children population in the territory of a large subject of the Russian Federation. In accordance with the action plan of the Health Department of the Voronezh Oblast, as well as in order to improve organization of dental services and statistical reporting and accounting in the autonomous health institution of the Voronezh Oblast, meetings concerning organization of dental services are organized. The issues are discussed concerning primary prevention of dental diseases in population of the Voronezh Oblast within the framework of the state program of the the Russian Federation "Health Care Development", organization and implementation of continuous medical education in dentistry, preparation and handing in annual report on dentistry in accordance with latest requirements of the Federal statistical monitoring in health care, new requirements of application of documents for preferential prosthetic dentistry in families of servicemen who perished during military service in peacetime.
