Unlabelled: Electronic nicotine delivery devices (ENDDs) are getting more and more popular among adolescents and young people under 25, signifying the beginning of tobacco product use for many of them. The state of the local microbiota can be affected by a large number of factors, namely the inhaled aerosol temperature, the oral cavity ph, the diet nature, genetics, etc.
Aim: The aim of the study was to identify the changes of dental microbiocenosis among adolescents who use devices for heating tobacco products and vape.
Corneal injury due to ocular trauma or infection is one of the most challenging vision impairing pathologies. The aim of the work was to study the effect of biodegradable silk fibroin-based scaffolds containing GDNF on the corneal regeneration process. During cultivate the highest keratocytes proliferative activity was registered with scaffolds containing 250 ng/ml and 500 ng/ml GDNF.

Purpose: To analyze the parameters of optical coherence tomography (OCT) and optical coherence tomography-angiography (OCTA) in patients with CSRC.
Material And Methods: The study included 10 patients (20 eyes) with CSRC, 15 healthy volunteers (30 eyes).
The Aim Of The Study: was to investigate the molecular genetic mechanisms of the influence of laser radiation with 577 nm wavelength in a microimpulse mode on the retina in the experimental conditions after the intravitreal injection of VEGF.
Materials And Methods: The study was performed on 4-5 week-old male mice of the line C57BL/6J. The animals were divided into 4 groups of 5 mice in each group, one eye was excremental, the contralateral eye remained intact.
Endohedral fullerences have great potential for a variety of techological applications. Here we consider B@C60 and show that the amount of charge transfer from the semimetal boron atom to the cage is a strong function of the radial distance of the atom from the center of the fullerene, and it is controlled by multistate conical intersections whose associated ridge of avoided crossings has the topology of a Euclidean sphere. The potential energy surfaces of B@C60 are characterized by two kinds of local minima: those with a boron atom located in the geometric center of the fullerene, and those with a boron atom bound to the fullerene inner wall.
