Synthesis, Characterization, Anticancer and Antimicrobial Potentials of Chrysothemis Pulchella Leaf Extract Mediated Gold Nanoparticles.
(Springer Nature, 2023-07-29) Ogwuche, C. E.; Elemike, E. E.; Daniel, O; Onwudiwe, D. C.; Moganavelli, S.; Akpeji, B. H.
In this study, Chrysothemis pulchella leaf extracts were used to prepare gold nanoparticles (AuNPs) for anticancer and antimicrobial applications. The nanoparticles were characterized using UV-Visible spectroscopy, powder X-ray diffraction method, Scanning and transmission electron microscopic (SEM/TEM) techniques. The UV–vis spectroscopy revealed characteristic absorption band at 527 nm whereas X-ray diffraction analysis showed characteristic crystalline peaks typical of AuNPs and carbon peaks emanating from the plant extract. The energy dispersive X-ray spectroscopic (EDXS) studies showed the following elements: C, O, Na, Mg, Cl, K, Ca and Au. The microscopic analysis using Scanning and Transmission Electron Microscopes showed spherical nanoparticles with average size of 14.7 nm. Cytotoxic tests showed that the AuNPs were toxic to human embryonic kidney (HEK-293) and HELA cells at IC50 dosage of 34.5 and 54.05 µg respectively. The nanoparticles also proved to have broad spectrum antimicrobial properties as they inhibited the growth of some pathogenic micro-organisms.

Cultural Values and the Crisis of Development: A Critique of African Governance Through Anyiam-Osigwe’s Holistic Philosophy
(2025-12) Iliaro, O. E.; Ogonegbu, F. C.
Africa’s persistent underdevelopment despite its vast human and material resources reflects a deep-seated philosophical and cultural crisis. The background of this study identifies governance failures, corruption, and moral decay as symptoms of a wider disconnection between indigenous African values and imported political systems. The problem lies in the erosion of communal ethics mutuality, reciprocity, and collective responsibility that once sustained pre-colonial societies, replaced by individualism and materialism that fragment governance and hinder progress. This paper examines these challenges through the lens of Emmanuel Onyechere Anyiam-Osigwe’s holistic philosophy, which emphasizes the “group mind,” moral integrity, and spiritual consciousness as the basis of authentic development. Using the method of philosophical analysis and hermuentics, the study analyses primary and secondary sources, including works by other African philosophers to interpret governance crises in relation to cultural dislocation. The findings reveal that Africa’s development stagnation stems not merely from economic or political inefficiencies but from moral and spiritual alienation disrupting communal harmony. The study also finds that gender imbalance and loss of spiritual consciousness further weaken leadership ethics and institutional accountability. It concludes that reclaiming cultural values through Anyiam-Osigwe’s holistic philosophy anchored on introspection, communal ethics, and divine interconnectedness can restore moral vision, strengthen governance, and promote sustainable development. The paper therefore advocates for policy reforms, value-based education, and culturally grounded leadership as essential pathways to Africa’s holistic renewal. Keywords: Cultural values; governance; holistic philosophy; development; Anyiam-Osigwe; African ethics

Phytochemical, Proximate and Antimicrobial Screening in the Aerial Part Plant of Drynaria Sparsisora
(Department of Process Engineering and Petrochemistry, Faculty of Technology, University of Echahid Hamma Lakhdar (University of El Oued) in El-Oued, Algeria., 2024-01-01) Ogwuche, C. E.; Odogwu, C. B.
After being gathered from the Uviwe local government area in Delta state, the leaves of Drynaria sparsisora were mixed, air-dried, and then extracted using a soxhlet apparatus with n-hexane and methanol as the solvents. Using the standard procedures of the Association of Official Analytical Chemists (A.O.A.C.), the phytochemical and proximate analysis was performed on the extract. Results of the phytochemical screening carried out on the combined extracts (n-hexane and methanol) showed the presence of alkaloids, proteins, sugars, glycosides, tannins, phenolic compounds, flavonoids, and steroids. To ascertain the moisture content, carbon, lipid content, ash, fat, and nitrogen, proximate analysis was used. According to the results, there was 1.2% fat and 50.4% carbon in the sample. The following were obtained for the others: lipid content (34%), ash content (6.5%), and nitrogen (6.69%). Mueller Hinton agar medium was used to test the antimicrobial activities of both extracts against a variety of clinical pathogenic microorganisms, including Helico bacterpylori, Campylo bacterjejuni, Escherichia coli, Salmonel platypi, Proteus mirabilis, Candida albicans, Candida krusei, and Candida tropicalis. The zones of inhibition were determined, and at various concentrations, the n-hexane and methanol extract demonstrated resistance to Escherichia coli, vancomycin-resistant enterococci, methicillin-resistant Staph aureus, candida krusei, and candida tropicalis. Methanol and n-hexane extracts have MICs of 25 µg/m and 50 µg/m, respectively. For the extracts of methanol and n-hexane, the MBC/MFC are 50 µg/m and 25 µg/m, respectively.

Availability and Utilization of Resources Discovery Services in Academic Libraries in Delta State.
(International Scientific Research Consortium (ISRC)., 2025-11) Njuku, Sheila U.; Nwachokor, Maureen I.; Okonkwo, Emmanuel; Okwudibe, Ernest
The study focused on academic libraries in Delta State, Nigeria, with emphasis on the challenges affecting their effective use of resource discovery services in academic libraries in Delta State and the strategies required for improvement. Four research questions guided the study. The study adopted a descriptive survey design. A total of 113 librarians across universities, polytechnics, and colleges of education in Delta state were surveyed for the study. Data were collected using an observation checklist and a structured questionnaire, and analyzed using percentages, mean scores, and standard deviations. Findings revealed that traditional cataloguing tools, such as manual catalogue cards and card indexes, remained the most widely available and utilized resource discovery mechanisms, while modern digital and metadata-driven discovery tools show limited availability and low utilization. Although systems such as OPAC, KOHA, Google Scholar, and EBSCOhost Discovery Service are gradually emerging, their usage were still minimal. Major challenges identified include inadequate funding, poor internet connectivity, fragmented or low-quality metadata, users' limited search skills, and low technological familiarity. The study further identified several strategies necessary for improving discovery services, including sustained funding, improved technological infrastructure, quality metadata management, system interoperability, information literacy programmes, and enhanced digital skills among librarians. The study concluded that while academic libraries in Delta State were transitioning between traditional and modern discovery systems, emphasizes should be made for increased investment and capacity building to fully optimize resource discovery services for improved access to information resources.

Digital Literacy Skills and Utilization of Electronic Information Resources in University Libraries in Delta and Edo States
(Department of Library and Information Science at Ambrose Alli University in Ekpoma, Nigeria., 2026-06) Ogaga, I. O. Gbemudu-Ughwumiakpor; Edewor, Nelson
The study investigated nexus between digital literacy skills and utilization of electronic information resources in university libraries in Delta and Edo states. It was guided by two (2) specific objectives, two (2) research questions and two (2) null hypotheses. It adopted the correlational research design, with a population of one hundred and thirty-six (136) academic librarians from twenty (20) public and private university libraries. The total enumeration sampling technique was used since the study population was small and quite manageable. The instrument for data collection was the researcher’s developed and expert’s validated structured questionnaire, with a cumulative reliability index of 0.88 determined with the use of the SpearmanBrown prophecy formula. The data collection process yielded 92% response rate from a total of 125 validly completed copies. The data collected were analyzed using descriptive statistics of frequency counts, mean, standard deviation and Pearson Product Moment Correlation for answering the research questions and analyzing the relationship between the variables, while the simple linear regression was used for testing the null hypotheses at 0.05 level of significance. The findings of the study revealed that digital literacy skills such as online search skills, social media skills of the librarians were moderately high and have a positive significant relationship with the utilization of electronic information resources across the university libraries in Delta and Edo States, Nigeria. The study concluded that digital literacy skills have a positive significant relationship with utilization of electronic information resources among librarians in university libraries in Edo and Delta States, Nigeria. Based on the findings, the study recommended among other measures that management of universities should make digital literacy skills mandatory requirements for appointment of librarians in the university libraries.
