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.

DETECTION OF EPSTEIN-BARR VIRUS (EBV) IN WOMEN WITH BREAST CANCER IN IRAQ USING IN-SITU HYBRIDIZATION AND IMMUNOHISTOCHEMICAL TECHNIQUES

Background: The Epstein-Barr virus (EBV) has recently been identified in human breast cancer globally, potentially contributing to the initiation and progression of this malignancy, as well as gastric cancer, nasopharyngeal carcinoma, and bladder cancer. It has been newly associated with breast cancer. Globally, breast cancer affects more women than any other type of cancer. In Iraq, the prevalence of breast cancer is comparable. Aims: The study examined Iraqi women diagnosed with invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) to detect Epstein-Barr Virus Nuclear Antigen-1 (EBNA-1) and encoded RNA (EBER). Methods: A total of 50 formalin-fixed paraffin-embedded tissues from invasive ductal carcinoma (IDC) (92%) and invasive lobular carcinoma (ILC) (8%) biopsy samples constituted the case group, while 30 formalin-fixed paraffin-embedded tissues from non-cancerous breast tissue served as the control group. The presence of Epstein-Barr virus protein (EBER) in breast tissue was assessed using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) methods. Results: EBER RNA signals were found in 31 (62%). EBER RNA signals were seen in 3 (10%) control group participants. Significant differences (P<0.04) were seen in EBV EBER RNA positive signals among study groups. Immunohistochemistry showed nuclear brown staining in 34 (68%) breast cancer patients. Control group: 3 (10%). Discussion: The research identified a statistically significant correlation between EBV positivity and breast cancer among Iraqi women, especially concerning invasive ductal carcinoma. The results corroborate previous reports of elevated EBV levels in malignant breast tissues relative to controls. Although detection approaches such as CISH and IHC provide complementary insights, additional studies are needed. Conclusions: The study concludes that EBNA-1 and EBV EBER RNA were overexpressed in our population group.

ASSESSMENT OF SERUM SCLEROSTIN LEVEL AS A BIOMARKER ASSOCIATED WITH BONE DISORDERS IN Β-THALASSEMIA PATIENTS IN AL- NAJAF CITY, IRAQ

Background: β-thalassemia is a blood disorder in which the body does not make hemoglobin normally. Aim: To assess serum sclerostin in female patients with beta-thalassemia and compare with the healthy controls and to predict its complication associated with the bone pathophysiology, for designed improvement the lifestyle goodliness for these patients. Material and methods: Sixty-nine female beta-thalassemia (βT) patients (54 βT major and 15 βT Intermedia), aged 8-40 years who dependent on transfused blood, and 20 healthy controls were evaluated serum sclerostin, and was examined the relationship with hematological parameters RBC, Hb, PCV, WBC, PLT, BMI, splenic status, iron, and ferritin levels. The information of beta-thalassemia patients was collected and records by the questioner. Results: A significantly increased serum sclerostin level (mean 26.80±0.91) pg/ml was showed in βT patients compared with the healthy controls (10.03±0.68, p  smaller than  0.001) pg/ml. Furthermore, a significant decrease (p smaller than 0.05) of the sclerostin level was observed in β-thalassemia major compared to intermedia β-thalassemia patients. Serum sclerostin level revealed a significant increase in progress age; it is highest in the age group (30-40) year as compared with age group (8-18) and (19-29) year respectively. Sclerostin showed no associations with the RBC, Hb, PCV, and significantly positively correlated (p smaller than 0.05) with serum iron, ferritin levels, WBC, and PLT count. Significantly higher sclerostin levels in splenectomized and underweight groups were observed compared to unsplenectomized and normal-weight groups (p smaller than 0.05) of βT patients. Conclusions: Sclerostin plays an important role in beta-thalassemia patients and can serve as a biomarker associated with the bone pathophysiology and indicator to prevent the continuation of such serious diseases caused by iron overload in these patients.

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.

USING SYNTHESISED ORGANIC COMPOUNDS AS ENVIRONMENTALLY FRIENDLY RETARDANTS FOR ORNAMENTAL PLANTS

The pre-sowing treatment of scarlet sage (Salvia splendens Ker Gawl.) seeds with 4-methyl-2-piperidin1-yl-pyrimidine-5-carboxylic acid at concentrations of 0.01, 0.05, and 0.1% proved to have an obvious inhibiting effect. Prior to sowing, the seeds of Salvia splendens were soaked in a water suspension of 4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid with concentrations of 0.01%, 0.05%, and 0.1% for 18 hours. On the 42nd day of the experiment, the seedlings, having been preliminarily hardened for 12 days, were removed from the greenhouse and planted on the field. The pre-sowing treatment of Salvia splendens seeds with 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid proved to have the inhibiting effect at concentrations of 0.01 and 0.05%. The height of the seedlings decreased by 13.3-43.7%. It was revealed that 4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid at concentrations of 0.01, 0.05, and 0.1% decreased the growth of the seedlings by 30.4-43.7%, and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid at concentrations of 0.01 and 0.05% decreased the growth of the seedlings by13.3-22.2%. By contrast, the effect of pyrimidinecarboxylic acids on seed germination and plant height of another annual flower – spreading marigold (Tagetes patula L.) was stimulating. It was investigated some different concentrations from 0.01 to 0.05 %. The same concentrations of identical compounds were tested, but effects from them were opposite for Tagetes patula, and Salvia splendens seedlings. Сonsequently, the species-specific effect of pyrimidinecarboxylic acids on seed germination and plant height for ornamental grasses takes place. Therefore,4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid and 4-methyl-2-morpholin4-pyrimidine-5-carboxylic acid are recommended as growth retardants for Salvia splendens.
