The growing consumption of processed seasoning, particularly Knorr, has raised scientific concern regarding their potential physiological effects, owing to the inclusion of additives such as monosodium glutamate (MSG), high salt content and synthetic flavor enhancers. This study investigated the effects of Knorr seasoning on Drosophila melanogaster across different concentrations. The flies were allocated into five groups: Group A (control), Group B (0.3 g), Group C (0.15 g), Group D (0.1 g), and Group E (0.05 g). Survival analysis revealed that Knorr seasoning significantly influenced lifespan (p = 0.006). Flies exposed to the highest concentration (0.3 g) exhibited the lowest survival rate by Day 21 (8.3%), whereas those treated with the lowest concentration (0.05 g) maintained a relatively higher survival rate (20.0%) compared to the control group (22.9%). A second setup was made and the flies was divided into five groups with varying concentrations to assess antioxidant enzyme activity. Catalase (CAT) activity showed no significant differences among groups (p = 0.624), while superoxide dismutase (SOD) activity varied significantly (p = 0.012). Glutathione peroxidase (GPx) activity did not differ significantly across treatment groups (p = 0.984). Overall, the findings demonstrated that Knorr chicken seasoning reduced the survival of Drosophila melanogaster in a concentration-dependent manner, with the greatest reduction observed at 0.3 g. Antioxidant enzyme assays indicated that Knorr seasoning selectively modulated SOD activity, suggesting heightened oxidative stress responses at higher concentrations and reduced activity at intermediate levels, whereas CAT and GPx activities remained largely unaffected. These results emphasize the critical role of dosage in determining whether Knorr seasoning exerts detrimental or potentially adaptive biological effects. Further investigations are warranted to validate these findings and explore the long term health implications of seasoning cube consumption.

Gastric damage is a common phenomenon in this part of the world, with about 70%–80% of the population having this issue. These have raised major concerns among experts in the medical field. The project “Investigating the Effects of Aqueous Leaf Extract of Camellia sinensis on Arsenic-Induced Gastric Damage in Adult Wistar Rats” aims to investigate the protective effects of aqueous leaf of camellia sinensis in arsenic-induced stomach damage in adult wistar rats. This study is an experimental research design that involves the use of 30 adult wistar rats, which were randomly divided into six groups (A-F). Group A served as the control group, Group B (Arsenic only), Group C (Arsenic+ Omeprazole), Group D(Arsenic+ low dose of extract), Group E(Arsenic+ high dose of extract) and Group F(Arsenic and left to recover). The rats were given water and feed ad libitum only for 14 days for acclimatization. Thereafter, the five treatment groups were given arsenic trioxide (10mg/kg) orally for 14 days to induce gastric damage. Group B rats were sacrificed for pilot study. Group C received Omeprazole(500mg/kg) for 28 days, Group D was administered low dose of the extract(250mg/kg) for 28 days, Group E received a high dose of the extract 500mg/kg) for 28 days also while the last group was left to recover without administering any extract and thereafter sacrificed by cervical dislocation. The results showed that rats treated with arsenic only had statistically significant decrease in body weight compared to the control group while the rats treated with camellia sinensis (250mg/kg) had statistically significant increase in weight compared to the rats in Group B. The rats in Group B had statistically significant decrease in organ weight compared to the control group. Group D had a significant increase in the organ weight compared to Group B. The antioxidant result showed a significant increase in superoxide dismutase, catalase and gluthaione peroxidase level and a significant decrease in malondialadehyde level in Group C, D and E. The histology results showed crater-shaped ulcers in the rats given arsenic toxin only. Normal mucosal lining was seen in the control group as well as in those given arsenic with omeprazole (the standard anti-ulcer drug). The rats given low and high doses of camellia sinensis showed pitting mucosal lining, with those given low doses having better ameliorative effects compared to those given high dose. The last group (reversal group), which were given only arsenic and left to recover, showed severe mucosal erosion. In conclusion, the research findings suggest that camellia sinensis (green tea) has the potential to mitigate arsenic-induced gastric damage in adult wistar rat.

Benin City, Edo State, faces increasing urban flooding and water scarcity due to rapid urbanization and limited public water supply. Rainwater harvesting (RWH) offers a sustainable solution by reducing surface runoff and supplementing household water demand. This study investigates the effectiveness of RWH as a stormwater management strategy, evaluates current practices, and explores its potential to improve water availability and mitigate flooding in selected locations within Benin City. A combination of field surveys, photographic documentation, household questionnaires, interviews, hydrological assessments, and case study reviews was employed. Field surveys focused on Upper Sakponba, Eyean Community, and Amagba Road, examining rooftop collection systems, storage tanks, and compound management such as grassing. Questionnaires assessed household awareness, adoption, and perceived benefits of RWH. Hydrological analysis using the Rational Method estimated rooftop runoff volumes, while Lagos case studies provided insights into large-scale RWH integration with green infrastructure and flood mitigation systems. Results show that many households practice RWH using plastic or concrete tanks, which reduces runoff and meets non-potable water demand, although adoption is limited by cost, technical knowledge, and space. Hydrological assessment confirmed that rooftop runoff can satisfy household water needs when storage is properly sized. The study recommends incorporating RWH into building codes, providing subsidies and technical training, promoting first-flush diverters and filtration units, and integrating RWH with urban stormwater measures such as retention ponds and green infrastructure
