Novel Flavin Mononucleotide-Functionalized Cerium Fluoride Nanoparticles for Selective Enhanced X-Ray-Induced Photodynamic Therapy.

X-ray-induced photodynamic therapy (X-PDT) represents a promising new method of cancer treatment. A novel type of nanoscintillator based on cerium fluoride (CeF) nanoparticles (NPs) modified with flavin mononucleotide (FMN) has been proposed. A method for synthesizing CeF-FMN NPs has been developed, enabling the production of colloidal, spherical NPs with an approximate diameter of 100 nm, low polydispersity, and a high fluorescence quantum yield of 0.

Using Spent Brewer's Yeast to Encapsulate and Enhance the Bioavailability of Sonochemically Nanostructured Curcumin.

This study is aimed at investigating the possibility of using spent cells of brewer's yeast to encapsulate the plant antioxidant curcumin and the effect of such an approach on the bioavailability of BAS in an digestion model. Spent brewer's yeast is a significant volume organic waste that is difficult to dispose of, which makes additional options for its use very promising. Encapsulation of curcumin into spent yeast cells was carried out in a nanostructured manner.

[The relationship of exudative age-related macular degeneration with lacrimal fluid chemokines in elderly patients.].

Age-related macular degeneration (AMD), along with other age-associated ophthalmologies, is a significant cause of loss of visual functions among the elderly, but the relationship of exudative AMD with lacrimal fluid chemokines has not been sufficiently studied. The aim of the work was to study the relationship of exudative AMD with lacrimal fluid chemokines in elderly patients. The content of chemokines in the lacrimal fluid was studied in 92 patients (184 eyes) 60-74 years old with exudative AMD and 84 patients (168 eyes) 60-74 years old without ophthalmopathology using a certified MAGRIX (USA) immunoassay device with Luminex technology on the xMAX platform.

Long term durability of Tc-bulk and Tc-coatings in various environmental conditions.

Technetium metal is renowned for its inertness in environmental conditions, rendering it an optimal candidate for use as a container material for high-level radioactive waste. Alternatively, thin technetium electroplated coatings can be employed to prevent corrosion of steel containers and the subsequent biofouling that may result. The utilization of metallic technetium in the design of containers for radioactive waste in deep burial may be promising from two perspectives: firstly, in terms of increasing their stability, and secondly, in terms of the utilization of technetium, which is a macrocomponent of radioactive waste.
