The Ambrose Alli University Library houses the information resources for the institution.The current vice-chancellor (acting capacity) of the university is Sunny Adagbonyi. He was appointed on 8 February 2022 by Governor of Edo state Godwin N. Obaseki.The former vice chancellor, Ignatius A. Onimawo is credited for his unique deployment and application of information and communications technology (ICT) in every aspect of the day-to-day running of the institution.
This study described the comparative green synthesis of magnesium oxide nanoparticles (MgONPs) using leaf extracts of Rubber (Hevea brasiliensis), Awolowo (Chromolaena odorata), and Oil palm (Elaeis guineensis) as reducing and stabilizing agents. Phenol- and flavonoid-rich phytochemicals promoted nucleation, growth, and stabilization of the nanoparticles. FTIR, DLS, SEM, XRD, BET/BJH, TGA and DTA, confirmed highly crystalline, thermally stable MgONPs with extract-dependent surface properties. Dynamic light scattering showed particle sizes of 44.57 nm (Awolowo), 100.3 nm (oil palm), and 100.5 nm (rubber) with polydispersity indices < 0.5. BET surface areas were 355.96, 318.61, and 251.00 m²/g, respectively, with mesoporous structures (2.10–2.13 nm). For environmental application, the MgONPs degraded methylene blue under sunlight with efficiencies of 92.82 A novel and eco-friendly micellar-enhanced ultrafiltration (MEUF) method was developed for selective gold recovery from waste mobile phone printed circuit boards (PCBs). The non-ionic surfactant TX-100 was identified as the most effective for gold recovery, achieving an efficiency of up to 96
Abstract Background Pediatric cancer care in Nigeria is constrained by several patient- and system-related factors. In line with the World Health Organization’s Global Initiative for Childhood Cancer, this scoping review mapped the Nigerian literature on diagnostic delays, treatment access, clinical outcomes, and related system gaps. Methods We searched PubMed, Cochrane Library, Scopus, African Journals Online (AJOL), Taylor & Francis Online, and Google Scholar. Eligible studies were in English, published 2005–2025, and included individuals 0–18 years. Findings were synthesized thematically and narratively. Results Twenty-seven tertiary hospital-based studies (n = 2,920) were included, representing all six geopolitical zones. Most were retrospective. Frequently reported malignancies included Burkitt lymphoma, nephroblastoma, retinoblastoma, Hodgkin lymphoma, and acute leukemias. Symptom-to-presentation intervals ranged from 2 to 157 weeks (median 79.5 weeks), and two studies separately reported symptom-to-diagnosis intervals of 13.4 weeks and 54.1 weeks, respectively. Contributors to delayed diagnosis and poor treatment access included low awareness, traditional or alternative care-seeking, initial misdiagnosis, financial barriers, long travel distances, limited insurance coverage, and broader health-system constraints. Using study-reported definitions, treatment completion was 3.3% in one study and 62.8% in another; treatment discontinuation was 6.3% in one study and 64.7% in another; mortality was 6.3% in one study and 45.1% in another; and cohort-level loss to follow-up was 6.6% in one study and 52.6% in another, reaching 81.8% among patients discharged on follow-up chemotherapy in one cohort. Conclusion Pediatric oncology care in Nigeria is marked by prolonged diagnostic pathways, interrupted treatment, and poor reported outcomes. Priorities include standardized referral pathways and integration of childhood cancer into national health insurance. Graphical abstract
Green synthesis of magnesium oxide nanoparticles (MgONPs) using natural extracts offers a biomedically and environmentally benign route for functional nanomaterial production. In this study, MgONPs were synthesized using aqueous extract from African oil palm leaves (Elaeis guineensis). The nanoparticles exhibited a mesoporous structure with an average pore size of 2.13 nm and a high surface area of 318.6 m²/g, enhancing bioactivity. Dynamic light scattering analysis showed an average particle size of 100.3 nm. Antioxidant activity assessed by DPPH assay revealed concentration-dependent scavenging, with moderate activity (IC₅₀ = 316 ± 4 µg/mL) compared to ascorbic acid (IC₅₀ = 204 ± 2 µg/mL). Antibacterial activity increased with concentration, showing inhibition zones of 18 mm (Escherichia coli) and 15 mm (Staphylococcus aureus) at 10 mg/mL, with stronger effects against Gram-negative bacteria. Photocatalytic studies under sunlight demonstrated 96.67
Magnesium oxide nanoparticles (MgONPs) were successfully prepared from leaf extracts of Elaeis guineensis (oil palm) and Hevea brasiliensis (rubber). Characterization using Fourier transform infrared spectroscopy, X-ray diffraction, dynamic light scattering, and BET analysis validated the presence of functional groups for stabilization, a face-centered cubic crystal structure, nanoscale dimensions (approximately 100 nm) with mesoporosity and high surface areas of 318.6 m2/g for oil palm and 251 m2/g for rubber. Rubber leaves (RL)-MgONPs had mild aggregation, while oil palm leaves (OPL)-MgONPs were monodispersed and evenly distributed. Antioxidant activity using the DPPH assay showed dose-dependent scavenging capacity with IC50 values of 316 mg/mL for OPL and 495 mg/mL for RL. OPL-MgONPs also displayed enhanced antibacterial properties against Escherichia coli and Staphylococcus aureus. Photocatalytic activity showed high methylene blue degradation (91.63% for OPL) with over 93% mineralization. The reduced size, increased surface area, and mesoporosity of OPL-MgONPs improved their reactive oxygen species activity, indicating their potential as eco-friendly multifunctional nanomaterials.
Background: Elder abuse is rapidly gaining attention as a concern globally, undermining not only the health, dignity, and quality of life of older adults but also having attendant social and public health consequences. Nevertheless, in Nigeria and several parts of the world, it is often underreported and neglected. This study assessed the prevalence, patterns, perpetrators, and factors associated with elder abuse in two urban communities of Edo State, Nigeria. Methods: A descriptive cross-sectional study was conducted among 257 elderly persons in Benin and Uromi, Edo State, from November 2019 to February 2020, using multistage sampling. Data were collected using a structured interviewer-administered questionnaire and analysed using IBM SPSS version 23.0. Descriptive and inferential statistics were conducted, with the level of significance set at p < 0.05. Ethical approval was obtained for the study. Results: The respondents had a mean age of 69.6 ± 7.8 years, with more than half aged 60-69 years (55.3%). The prevalence of elder abuse was 29.2%, and the common types were emotional abuse (85.3%), neglect (84.0%), financial abuse (78.7%), and physical abuse (69.3%). The main perpetrators were children (50.7%), followed by house helps and caregivers (17.3%). Associated factors included educational status, financial dependency, living arrangements, health status, marital status, and age. Conclusion: Elder abuse is a common and serious public health issue in the study setting. Hence, there is a need for social and welfare support, community-based awareness, and interventions to promote respectful ageing and enhance the prevention and early detection of elder abuse.
