I. Lenin Georgian Polytechnical Institute) is the main and largest technical university of Georgia. It is located in the capital city of Tbilisi.
Healthcare, like other countries, is a vital sector for Georgia, and Georgian mass media play a significant role in the effective management of its policy. Health communication through the media is a multifaceted, contradictory process that requires: appropriate competence, responsibility, unwavering adherence to professional standards, accurate reflection of reality, maintaining an impartial balance, ethical analysis of issues, and ensuring access to information. Georgian media contributes to the formation of an informed society, raising the level of knowledge and behavior of the population, which is a prerequisite for improving the quality of public health. The media, as a PR tool for public relations, played an important role in the crises caused by the COVID-19 pandemic in Georgia during the quarantine period.
Magnetic nanoparticles are currently gaining significant attraction in various fields, including modern engineering and ecology, particularly in biomedical, therapeutic, and diagnostic technologies. An environmentally friendly electrochemical synthesis method was used to produce magnetic nanoparticles. Iron sulfate was dissolved in a mixture of water-ethanol, while polyvinylpyrrolidone (PVP) was used to enhance the biocompatibility of the magnetite nanoparticles. Particle size in a sol obtained with 1 vol% PVP, at a current density of 20-60 A/dm2, and at varying water and ethanol ratios, was measured using the dynamic light scattering (DLS) method transmission electron microscopy (TEM). Zeta potential was measured to determine the stability of the magnetite sol. In the presence of PVP, the best results (12-18 nm) were obtained with water/ethanol ratios of 50/50 and 60/40 vol.%. Magnetite nanoparticles were characterized using a Zetasizer Malvern instrument, scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis.
One of the important directions of social policy is health policy, the goal of which is to protect the health of the population, prevent various diseases, and ensure equal access to medical services. The presented paper discusses health policy in the context of social policy using the example of Georgia, analyzes the role of the state, the dynamics of reforms, and existing challenges. It is noteworthy that the attention of the political spectrum in Georgia has always been focused on healthcare policy in the context of social policy (especially during the pre-election period). Despite some progress in the country, many issues remain pressing problems. The experience of Georgia shows that health policy development requires not only an increase in financial resources, but also strategic planning, institutional strengthening, and an approach based on the principles of social justice.
The electrochemical and spectrophotometric behavior of Olanzapine (OLZ) was studied for its optimal concentration ratio towards citrate buffer solution, the half-wave potential of a mercury dropping electrode, and electrochemical and spectrophotometric calibration curves for the qualitative and quantitative determination of OLZ. The influence of various solvents on the ability of OLZ to form complexes with metals has been evaluated using the quantum-chemical semi-empirical AM1 method. The energetic, electronic, and structural characteristics of the molecule have been calculated, and the donor atoms in the OLZ molecule and the rules of its coordination with the metal atom have been identified. These studies are vital for further research evaluation of OLZ presence in blood plasma and urine. The removal of OLZ from model solutions was tested using the carbonaceous materials of hazelnut and walnut shells (obtained by our method), and their adsorption capacity was compared with industrial carbon material - Activated Birch Carbon (BAU-A) - showing compatible results.
There is an increasing necessity for advanced, sustainable, and biocompatible materials for wound healing as therapeutic and diagnostic products. Marine environments, characterized by high biodiversity, offer an underutilized source of natural resources with enormous potential for creating novel materials for dressings. This review highlights the revolutionary nature of polymeric biomaterials of marine origin, with a focus on polysaccharides, like alginate, chitosan, and carrageenan; proteins, such as collagen and gelatin. These biopolymers are outstanding in their physicochemical properties, such as biodegradability, bioactivity, and modifiable mechanical strength, which enable their use in wound-healing systems. Besides, these biomaterials may be easily chemically and physically modified, enabling enhanced multifunctionality and integration into complex biomedical environments. Marine-based biopolymers are renewable, abundant, and offer environmentally benign alternatives to synthetic materials, thereby resolving sustainability concerns in large-scale biomedical manufacturing. This report addresses the recent development of maritime-derived polymers and the resulting wound dressings for state-of-the-art wound healing, highlighting significant challenges and future perspectives.
