Strategy for Patterning Titania Dendrites by Gas-Solution Interaction at Droplet Surfaces.

Interaction of the solution droplet surface with gaseous components of the environment can lead to the formation of highly ordered patterns, such as dendrites. Here, we show that these structures can be spontaneously created during the open-air interaction of aqueous solution drop of titanium(III) salt with gaseous NH at the contact boundary thereof. The conditions have been identified under which radially ordered dendritic patterns can form on the surface of the TiCl solution droplet.

[Investigation of ligand-receptor interaction and biodistribution of a drug containing cattle retinal polypeptides in various administration routes].

Unlabelled: It is important to understand the features of the interaction of drug components with body receptors and obtain data on its distribution in various administration routes in recommended doses in order for its usage in clinical practice to be safe and effective.

Purpose: To investigate the interactions of a drug consisting of water-soluble polypeptide fractions produced on animal retina with a wide range of receptor targets, and to assess its biodistribution in the organs of laboratory animals.

Material And Methods: The biodistribution of the radioactively marked drug in different organs and tissues of laboratory mice in various routes of administration was studied at the National Research Centre «Kurchatov Institute».

Oxygen Generation Using Catalytic Nano/Micromotors.

Gaseous oxygen plays a vital role in driving the metabolism of living organisms and has multiple agricultural, medical, and technological applications. Different methods have been discovered to produce oxygen, including plants, oxygen concentrators and catalytic reactions. However, many such approaches are relatively expensive, involve challenges, complexities in post-production processes or generate undesired reaction products.

[Treatment of patients with a cerebral arterial aneurysm and stenosis of the internal carotid artery].

Aim: The purpose of this study was to analyse the world literature dedicated to the problem concerning treatment of a combination of internal carotid artery stenosis at the extracranial level and an arterial aneurysm of the brain, as well as to demonstrate own results of surgical treatment of patients presenting with this concomitant pathology of the carotid basin.

Patients And Methods: From 2013 to 2019, a clinical course of combined pathology of the basin of the internal carotid artery (an intracranial aneurysm and stenosis of the internal carotid artery at the extracranial level) was revealed in 35 of 1638 examined patients. There were ten men and 25 women, with a mean age of 66±7 years.

Synthesis of the FeOOH Microtubes with Inner Surface Modified by Ag Nanoparticles.

Lepidocrocite (γ-FeOOH) microtubes with scroll morphology prepared by gas-solution interface technique (GSIT) have been modified by silver nanoparticles (Ag NPs). The successive ionic layer deposition (SILD) was first used for the synthesis of the Ag NPs on the lower surface of a solid film freely lying on the surface of a solution. The sizes of Ag NPs are about 15 nm after one synthesis cycle, and their diameters reach 35 nm after three SILD cycles.
