THE REVOLUTION IN AMERICAN PUBLIC HEALTH POLICY: PETROLEUM-BASED DYES AND THE CHRONIC DISEASE EPIDEMIC

Background: The American food regulatory landscape has historically been influenced by industry interests, resulting in the widespread use of petroleum-derived synthetic food dyes banned in European countries. Chronic disease rates in American children have increased from 3% in the 1960s to approximately 60% currently, with annual healthcare costs reaching $1 trillion. The appointment of Robert F. Kennedy Jr. as Secretary of Health and Human Services marks a paradigmatic shift toward transparency and industry accountability in food safety regulation. Aim: This forum analysis examines Kennedy Jr.'s revolutionary approach to food safety regulation, particularly his confrontational stance against petroleum-based food additives exemplified by his statement, "if they want to eat petroleum, they should add it themselves at home" and evaluates the broader implications for American public health policy and global regulatory standards. Methods: Critical analysis of Kennedy Jr.'s public policy statements, examination of epidemiological data trends, and evaluation of proposed regulatory frameworks through content analysis of official speeches and policy declarations from the Department of Health and Human Services. Results: Kennedy Jr.'s administration targets the systematic elimination of synthetic food dyes through industry partnerships, scientific transparency initiatives, and restoration of rigorous research standards. His confrontational rhetorical approach, compared to Mike Tyson's boxing style, has generated unprecedented industry cooperation with food companies "calling almost daily" seeking compliance guidance. The strategy combines voluntary industry agreements with open-source information databases and enhanced FOIA access. Discussion: This confrontational rhetoric represents unprecedented directness in health policy communication, challenging decades of established regulatory practices. The approach prioritizes scientific transparency over diplomatic language, generating both media attention and voluntary industry engagement that traditional regulatory pressure failed to achieve. Conclusions: Kennedy Jr.'s revolutionary stance may establish new global standards for food additive oversight, prioritizing public health over commercial interests through evidence-based policymaking and industry accountability measures. This paradigm shift from reactive to preventive regulatory models could influence international food safety governance and restore American leadership in global health policy.

RESEARCH LANDSCAPE OF REPURPOSED MEDICATIONS IN CANCER TREATMENT: A MULTI-DATABASE BIBLIOMETRIC ANALYSIS OF ELEVEN OFF-PATENT THERAPEUTICS

Background: Drug repurposing offers potential advantages for cancer therapy development, particularly when utilizing medications with established safety profiles and expired patents. While individual repurposed medications have been investigated for oncological applications, comprehensive comparative analyses of research distribution patterns across multiple therapeutic candidates appear limited in the literature. Understanding these patterns may provide insights into research priorities and potential knowledge gaps. Aim: This exploratory study was designed to quantify and compare the volume of scientific literature examining the anticancer potential of eleven selected off-patent medications across different pharmacological classes. Methods: Bibliometric searches were conducted across five databases (Google Scholar, BVS, PubMed, NIH, and Science.gov) using standardized search terms combining each medication name with "cancer" and "cancer treatment." The selected medications included ivermectin, fenbendazole, mebendazole, albendazole, metformin, propranolol, disulfiram, valproic acid, thalidomide, dexamethasone, and hydroxychloroquine. Basic statistical analyses were performed to examine the distribution patterns and correlations within the database. Results: The search yielded 3,226,066 total publications with considerable variation in distribution patterns. Dexamethasone accounted for the largest proportion (1,538,058 publications, 47.68%), followed by metformin (697,172 publications, 21.61%). Some medications with smaller overall publication volumes demonstrated higher proportions of treatment-specific research, such as fenbendazole (87.82%), disulfiram with copper (86.54%), and hydroxychloroquine with zinc (75.21%). The Herfindahl Index indicated a high concentration of research attention (0.2870). Discussion: The findings suggest substantial variation in research attention across the selected medications. While some medications dominate the literature, others with focused treatment-specific research may warrant further investigation. The inverse relationship observed between total publication volume and treatment specificity suggests that research patterns in this field may be more complex than absolute publication counts indicate. Conclusions: This preliminary bibliometric assessment reveals an uneven distribution of research attention among repurposed medications being investigated for cancer applications. These patterns may inform future research prioritization, though further qualitative analysis would be valuable to assess the clinical significance of these quantitative observations.

CLINICAL AND LABORATORY TESTING OF A NEW MODIFICATION OF TWO-LAYER "SILEP" DENTURES USED IN PROSTHETIC DENTISTRY

Dentistry is a part of medicine, where various polymer materials were used for the first time. Many factors forced researchers to find more stable, versatile, and hygienic materials for the manufacture of dental products. It is important to note that the search for the ideal polymer dental material is still ongoing. This is because modern polymers, in some cases, do not meet the specified requirements for chemical, physical, strength, and elasticproperties. Based on the data on the method of creating and using silicone material for the base of the removable prosthesis "Gossil", an improved silicone material for two-layer dentures "Silep" was developed, as well as a special primer for better connection of the lining with the rigid acrylic base of the prosthesis. To evaluate the most suitable compound, materials were tested for several parameters, such as tensile strength, elongation, and shore hardness. In addition to selecting a suitable material for modification, the selection and testing of an adhesive that allows the chemical bonding of the acrylate surface to the siloxane surface were carried out.

SELF-ASSEMBLED MULTILAYERS OF WATER GLUCOSE MODIFIED-CHITOSAN AND GLUCOSE OXIDASE FOR DETECTION OF GLUCOSE IN MILK SAMPLES

Background: A crucial aspect of electrochemical enzymatic biosensor development is the immobilization of the enzymes, as it directly influences the sensitivity of the bioelectrode. Among the different methods used to incorporate enzymes on the surface of the transducers, layer-by-layer (LbL) self-assembly based on electrostatic interaction with polyelectrolytes of opposite charge stands out due to its simplicity and reproducibility. Aims: The aim of the work was to develop an electrochemical glucose biosensor by LbL assembly of a new functionalized chitosan polycation and the enzyme glucose oxidase (GOx). Methods: Chitosan was chemically functionalized with glucose by the Maillard reaction. The resulting polycation, named G-Chit, is soluble in the medium compatible with the enzyme. The bioelectrode was obtained by alternating adsorption of G-Chit and GOx onto carbon paste electrodes. By selecting the number of bilayer of G-Chit/GOX, the enzyme concentration, and the pH, the electroanalytical performance of the biosensor was optimized. The electrochemical responses were characterized by cyclic voltammetry and chronoamperometry. Results: Under optimized experimental conditions, the biosensor exhibited a sensitivity of (0.81 ± 0.03) µA mM-1 in a glucose concentration range of (0.18 to 1.75) mM. Discussion: Results indicated that catalytic response increases both with the number of G-Chit/GOx bilayers and the enzyme concentration, obtaining the best responses for 3 bilayers and 2 mg mL-1, respectively, while the optimum working pH value was 7.0. Conclusions: The analytical response of the biosensor was tested in milk samples with negligible matrix effects, suggesting a potential application in other dairy products. Results show that G-Chit appears promising for the immobilization of enzymes.
