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.

INQUIRY FOR SUITABLE LOCATIONS FOR A DRILLING REGIME AT AN UPSLOPE ROCKY KNOLL OF LAWU ESTATE, WESTERN BYPASS, MINNA, NIGERIA

Background: A client requested that the study group help determine locations that would be suitable for a drilling regime at his lot, located at an upslope rocky knoll of Lawu Estate, Minna, Nigeria. Aim: The aim of this study is to carry out a purpose-specific survey to pinpoint the best locations in a built-up property at the upmarket Lawu Estate that would be suitable for a drilling regime targeted for household consumption. Methods: The study area was reconnoitered by the survey crew in order to georeference the locations that would be occupied for the vertical electrical sounding survey in the 30 m x 20 m lot. Owing to the extensive build-up at this lot, only a four-point traverse along the 30-metric dimension traverse of the frontage of the building was demarcated in the northeasterly direction, thereby limiting the desire of the survey crew to define an appropriate survey grid. The data-acquisition pattern at the 4 x 1 survey stations of the frontage-traverse of the lot followed the “traditional” sequence of Schlumberger array layout measurements, whence the survey crew progressed with current-electrode spacing either end of a survey point located at this frontage-traverse targeting a maximum survey depth of 100 m. Result: The acquired vertical electrical-sounding data set for this study was recorded on purpose-specific data sheets. Discussion: Based on empirical rules-of-thumb procedures for interpreting vertical electrical sounding data at the Nigerian Basement Complex geological province, “assured” groundwater location and “strongly aquiferous” location, deductive inferences were drawn with regards to only vertical electrical sounding Station 4. Conclusion: Thus, it is recommended that VES Station 4 be exploited in the planned drilling program of the client, especially since this survey point checks off 100 percent of the constraints imposed by the rules-of-thumb interpretation procedures.

TREATMENTS FOR ACUTE LYMPHOBLASTIC LEUKEMIA: A COMPARISON BETWEEN TISAGENLECLEUCEL AND CLOFARABINE

Background: Acute lymphoblastic leukemia (ALL) is a heterogeneous hematological malignancy predominantly affecting individuals under 20 years of age. Traditional chemotherapy, such as clofarabine, has shown efficacy; however, novel immunotherapeutic strategies like tisagenlecleucel (Kymriah®) have significantly altered the treatment paradigm. Aim: This study aimed to perform a comparative analysis of tisagenlecleucel, a CAR-T cell therapy, and clofarabine, a second-generation purine nucleoside analog, evaluating their mechanisms of action, therapeutic benefits, limitations, and clinical applicability across diverse patient populations. Methods: A systematic comparative evaluation was conducted, encompassing pharmacological characteristics, mechanisms of action, treatment protocols, efficacy, safety profiles, and clinical indications of both agents. The analysis considered pharmacokinetic and pharmacodynamic data and included patient demographic variables. Results: Tisagenlecleucel demonstrated high efficacy in refractory B-cell ALL, with durable responses and a blood half-life of 128 days, but with notable immune-related adverse effects such as cytokine release syndrome. Clofarabine, effective across a broader patient population, acts via multiple antitumor mechanisms but carries significant toxicity risks, including infection and sepsis. Discussion: The therapies present distinct clinical profiles: tisagenlecleucel offers targeted immunotherapy with high specificity but requires specialized infrastructure and management of immune toxicities. Clofarabine is more widely accessible and applicable, but is associated with conventional chemotherapy-related side effects. Treatment accessibility and cost differ markedly between the two. Conclusions: Therapy selection should be personalized based on patient-specific factors and institutional resources. Tisagenlecleucel is ideal for pediatric and young adult patients with relapsed/refractory B-cell ALL in CAR-T-capable centers, while clofarabine remains a viable option for broader ALL populations, particularly when genetic therapies are not feasible. Further research is needed to optimize therapeutic strategies and improve access to advanced treatments.

EXTRACTION AND CHARACTERIZATION OF CURCUMIN FROM TURMERIC RHIZOMES GROWN IN MÉRIDA, VENEZUELA

The extraction of naturally occurring compounds is one of the fastest-growing industries because of its benefits against its synthetic analogs. Environmental protection must require the use of natural products instead of chemicals to minimize pollution. Thus, this investigation studies the use of some natural product, as curcumin, as naturally occurring acid‐base indicators. Curcumin can be used as acid-base indicators since it was found that it possesses pH-dependent solubility. Curcumin, the major active component of turmeric, Curcuma longa (Zingiberaceae), is used as a spice in curry and as a coloring agent in yellow mustards, cosmetics, pharmaceuticals, and hair dyes. In this research, the main compound colored rhizome of turmeric (Curcuma longa) cultivated in Mérida, Venezuela, is extracted: Curcumin (C21H20O6) (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione, in a yield of 3.42% after 8 hours of extraction using soxhlet extractor system with organic solvents (hexane and ethanol). The thin-layer chromatography and column performed separation and purification using a mobile phase, a mixture of chloroform-hexane 3:2. The dye was characterized by spectroscopic analysis of visible ultraviolet (UV-Vis) and infrared (IR), in addition to his studio in steering sensitivity as an acid-base indicator. This dye is useful as an acid-base indicator in strong acid-strong base volumes and did not require large amounts of it as it has high sensitivity. The results indicate that curcumin as an acid-base indicator allows the development of new standards in different chemistry fields that require this type of analysis.

GEOSPATIAL IDENTIFICATION OF BUILT-UP STRUCTURES ALONG THE DISCERNED KAZAURE–KARAUKARAU–KUSHAKA–ILESHA SCHIST BELT

Background: The desire to create a database of research documents providing information about the tracts of gold deposits across the local geological province provides the impetus for a study of the kind being considered here. Geospatial identification of built-up structures within Phase I Development along the Kazaure-Karaukarau-Kushaka-Ilesha Schist Belt, trending through Minna town and its outlying districts, constitutes the veritable reference material desired in this regard. Methods: This study began by segmenting the area of study for ground-based and remotely sensed attribute mapping, using the key reference map from a previous study as the area-of-study guide. A handheld Garmin GPSmap78® global positioning system unit and a standard smartphone with a built-in camera were the key equipment used for the fieldwork. Polygonal-format georeferenced coordinate information was collected at conveniently detached buildings, beginning with the cluster of residential homes at the Staff Quarters, for the ground-based survey. Result: Nine of the ten built-up structure clusters on the path of the Belt in Phase I Development were mapped for this study, as well as six neighborhoods in the Minna built-up area beyond Phase I. The nine clusters occupy almost 40% of the circa 2 km2 areal extent of the Phase I Development. The belt's trend and structures were north-northeast. Discussion: The nine cluster structures in Phase I and the six neighborhoods of Minna identified in this study have been determined to align with the path of the belt. Conclusion: Having now determined that the trace of the belt exits the Campus at the northern sector of the Gidan Kwano village and trends in a long arc beyond the town, this study becomes the desired reference material to be archived and consulted for information relating to gold exploitation in the Minna Area geological province.

BUNCH NUMBER AND ANTIOXIDANT ACTIVITY IN ‘SAHEBI’ AND ‘HALAGHO’ GRAPES AFFECTED BY PRUNING INTENSITY AND CANE LENGTH

Pruning methods can primarily affect grape production at various levels. Of the commonly affected features by pruning, the number of bunches has known to have a significant effect on the relation between the functions of assimilate sources and sinks. Further, fruitfulness can significantly be negatively influenced by shading. In this study, we aim to study the impact of 4, 6 and 8 buds per cane with pruning intensity as light, moderate and severely pruned and their interaction in the course two consecutive years, 2017 and 2018 in ‘Sahebi’ and ‘Halagho’ (both seeded red table grape cultivars). In 2018, lightly pruned ‘Halagho’ and having 8 buds per cane increased number of bunches by 54.00, which had the highest value. Results showed that there is apical buds bear more fruit by comparison to the buds with vegetative nature, 1 to 4 first buds. Based upon the outcomes of this study, it could be concluded that due to the stresses imposed by the pruning of the vines, therefore, the chemical compounds increases in order alleviate the negative aftermaths . In 2018, whole berry antioxidant activity in both cultivars was significantly lessened, and this decline was higher in ‘Saahebi’. The number of bunches was increased by increasing cane length or bud load/cane. Overall, the pruning program has an impactful role in bunch number as well as antioxidant activity and in the long-run on accumulated reserves, which makes choosing and applying a specific pruning method undeniably important. Thus, emphasize the importance of further research in this field.
