Phytotoxicity of the aqueous solutions of some dishwashing detergents for dishwashers with phosphonates and without phosphates.

The influx of insufficiently purified or untreated domestic wastewater into aquatic ecosystems raises the question of the production of environmentally friendly detergents. The purpose of this work was to investigate the toxicity of phosphonate-containing and phosphate-free dishwashing detergents for dishwashers according to the phytotest with a garden cress ( L.).

PATTERNS OF DEVELOPMENT OF CLINICAL AND FUNCTIONAL DISORDERS OF THE BRONCHOPULMONARY SYSTEM IN THE POST-ACCIDENT PERIOD IN PERSONS EXPOSED TO IONIZING RADIATION.

The objective was to study the relationship between clinical symptoms and the functional state of the bronchopulmonary system of clean-up workers of the Chornobyl Nuclear Power Plant accident with chronic obstructive pulmonary disease in the remote post-accident period.Materials and methods. A retrospective analysis of 824 cases of COPD in male patients who underwent inpatienttreatment in the radiation pulmonology department from 2014 to 2024 was conducted.

Microbiological indicators of the biofilms microparticles of quartz sand and polypropylene after short-term exposure in soil.

The purpose of this study was to investigate dynamics of biofilm biomass on microparticles of natural material quartz sand and the artificial material polypropylene (plastisphere) as well as change in biofilm-forming microorganisms' number under a short-term field study. In this study microparticles of polypropylene and quartz sand ranging in size from 3 to 5 mm were used. The total microbial count and the number of sulfate-reducing bacteria in the biofilm (by traditional culture-based microbiological methods) and the biofilm biomass (by the method with the crystal violet) were investigated.

THE COMBINATION OF CHRONIC RESPIRATORY DISEASES WITH OBSTRUCTIVE SLEEP APNOEA SYNDROME IN CLEAN-UP WORKERS OF CHORNOBYL NPP ACCIDENT.

Unlabelled: The objective of the study was to establish the relationship between functional status of bronchopulmonary system and obstructive sleep apnea in clean-up workers of Chornobyl NPP accident in a remote post-accident period.

Materials And Methods: We included 58 COPD male patients clean-up workers of Chornobyl NPP accident: 21 with obstructive sleep apnea syndrome (OSA), 37 - without. A complex of functional tests and OSA screening was provided.

The Role of Lyophilized Xenodermotransplants in Repairing the Atria's Structure and the Peculiarities of Regenerative Processes after Thermal Trauma in an Experiment.

The effects of severe burn injuries on the cardiovascular system, specifically the atria and auricles of the heart, were investigated. The potential benefits of using lyophilized xenodermotransplants as a treatment option were also evaluated. The experiments were conducted on adult guinea pigs divided into three groups: intact animals, animals with burns, and animals with burns who underwent early necrectomy followed by wound closure with lyophilized xenodermotransplants.
