EVALUATING THE EFFICACY OF T. AFRICANA EXTRACTS COMBINED WITH CONVENTIONAL ANTIBIOTICS AGAINST MULTIDRUG-RESISTANT PATHOGENS
type: item
description: The global rise of multidrug-resistant (MDR) pathogens threatens the efficacy of conventional antibiotics, necessitating novel therapeutic strategies. This study evaluates the efficacy of Terminalia africana (T. africana) methanolic extracts combined with antibiotics (ampicillin, ciprofloxacin, ceftriaxone) against MDR Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus (MRSA). Grounded in the multi-target hypothesis, which posits that plant extracts enhance antibiotic action by targeting multiple bacterial sites, we employed a primary experimental design. In vitro assays, including minimum inhibitory concentration (MIC) determination, checkerboard synergy testing, and time-kill kinetics, were conducted using clinical isolates from Lagos, Nigeria. T. africana extracts alone exhibited MICs of 64–256 µg/mL, while combinations with antibiotics reduced MICs by up to 4-fold. Checkerboard assays revealed synergy (fractional inhibitory concentration index, FICI ≤ 0.5) in 70% of combinations, notably with ampicillin and ciprofloxacin, reducing bacterial viability by 3-log10 within 12 hours in time-kill assays (p < 0.01). Ceftriaxone combinations showed indifference (FICI 0.75–1.25), possibly due to β-lactamase resistance. These findings suggest that T. africana extracts disrupt resistance mechanisms, enhancing antibiotic potency. The study underscores the potential of plant-based adjuvants in combating AMR, particularly in resource-limited settings.

The current study was conducted to assess the phytochemical constituents and antimicrobial activity of bitter leaf on Candida albicans, Pseudomonas aeruginosa and Staphylococcus aureus. The result of the phytochemical analysis conducted on the root and stem bark of V. amygdalina revealed the presence of alkaloids, tannin, steroids, flavonoids, phenol, and saponins. However, it was found that tannins and phenol were mainly deposited in the plant's stem bark. Also, the antimicrobial analysis conducted revealed that S. aureus was more vulnerable to the ethanol, acetone, and hot aqueous extracts of V. amygdalina. while, P. aeruginosa, and C. Albicans showed sensitivity to ethanol and acetone exposure but failed to react to the hot aqueous extracts. The study concludes that the observed biological reactions shown by the aqueous extracts of V. amygdalina corroborate the traditional application of this plant as an alternative antibiotic.

VIRTUAL GUIDED LABORATORY APPLICATIONS ON THE VERIFICATION OF OHMS LAW
type: item
description: Ohm’s Law has long been a cornerstone of electrical engineering, providing a linear relationship between voltage, current, and resistance that has underpinned modern circuit analysis. However, as technology advances and philosophical inquiries deepen, the limitations of this venerable law have become evident, particularly in scenarios involving near-zero resistance. This paper introduces a novel formulation-the modified Ohm’s Law; that not only rectifies the pitfalls of the conventional law but also harmonizes physics with philosophical principles. Motivated by the perplexing issue of predicting infinite current at zero resistance and the philosophical implications of deriving infinity from the finite, the modified equation serves as a bridge between empirical insights and logical coherence. Through rigorous mathematical derivation, comprehensive theoretical examination, and scrupulous computational analysis, the accuracy and applicability of the modified Ohm's Law are not only demonstrated but also its suitability across a wide range of scenarios is revealed. These scenarios include semiconductor devices, high-current applications, and complex systems where the standard Ohm’s Law falls short, offering a transformative perspective on the analysis of electrical circuitry. In reconciling scientific rigor with philosophical consistency, this paper advances our understanding of electrical circuitry and beckons a newera of precision in analysis. Further, the modified Ohm’s Law paves the way for deeper explorations that resonate through the domains of physics and philosophy, reshaping the landscape of our understanding

CORN HUSK FERMENTATION WITH BREWERY WASTE YEAST AS FISH MEAL SUBSTITUTE IN THE DIET OF AFRICAN CATFISH (Clarias gariepinus) FINGERLINGS
type: item
description: This study was conducted to evaluate the effect of partial substitution of fish-meal (FM) with two types of fermented animal by-products (fish and poultry offal‟s wastes) on growth performance, microbiological, and fish quality of African catfish (Clarias gariepinus). Fish offal‟s silage (FOS) and poultry offal‟s silage (POS) were fermented by Lactobacillus acidophilus. Five isonitrogenous (34.3% crude protein) diets were formulated to comprise two levels of fermented fish offal (20% and 40%), two levels of fermented poultry offal (20% and 40%) wastes, and 100% fish meal as a control. Ninety hatcheries bred African catfish were randomly distributed into 5 equal groups every 18 fish in three replicate (6 fish/ replicate aquaria). Each of the diets was fed to triplicate groups of African catfish with mean initial weight (MIW) 52g ± 0.01 at 5% body weight in glass aquaria (30 x 30 x70 cm) twice daily (morning and evening) for 12 weeks. The results showed that fish in the fourth group fed on diet supplemented with 20 % POS recorded the best feed conversion ratio (FCR) (1.77±0.1), protein efficiency ratio (PER) (3.51±0.06), incidence of cost (IC) (16.3±0.37), and profit index (PI) (3.51±0.06). Fish in group four as well had the least total bacterial count, coliform, and mold & yeast. The least lactic acid bacteria count and the best overall acceptance were detected also in the fourth group as compared to other groups except diet 1(control) which means it can be used safely without significantly affecting public health or consumer acceptance.

ASSESSMENT OF TOTAL PETROLEUM HYDROCARBON IN SEDIMENT ALONG THE PORT HARCOURT SHORELINE IN RIVERS STATE
type: item
description: The contamination of marine and coastal environments by petroleum hydrocarbons is a significant environmental concern, particularly in regions with extensive oil exploration and production activities. This study aims to assess the concentration and distribution of total petroleum hydrocarbons (TPH) in sediment along the Port Harcourt shoreline in Rivers State, Nigeria. Sediment samples were collected from ten different locations along the Port Harcourt shoreline between January and June 2024. The samples were analyzed for TPH using gas chromatography-mass spectrometry (GC-MS). Physicochemical parameters such as pH, temperature, and organic carbon content were also measured. Data were statistically analyzed to determine the spatial distribution and potential sources of TPH contamination. The results indicated that TPH concentrations in the sediment samples ranged from 1.5 mg/kg to 12.8 mg/kg, with the highest concentrations observed near industrial discharge points and oil spill sites. The average TPH concentration was 6.4 mg/kg, exceeding the permissible limits set by environmental regulatory agencies. The spatial distribution pattern suggested that the primary sources of TPH contamination were petrogenic, originating from oil spills and industrial discharges. The physicochemical analysis showed a significant correlation between TPH levels and organic carbon content in the sediment. The study highlights the high levels of TPH contamination in the sediment along the Port Harcourt shoreline, posing potential ecological risks to marine life and human health. There is an urgent need for stringent regulatory measures and effective remediation strategies to mitigate the impact of petroleum hydrocarbon pollution. Continuous monitoring and public awareness campaigns are essential to protect the coastal environment and ensure sustainable development in the region.
