Distribution and status of the African forest buffalo Syncerus caffer nanus in south-eastern Nigeria

AbstractAlthough not categorized as threatened on the IUCN Red List, the African forest buffalo Syncerus caffer nanus is declining across its range. In Nigeria its distribution, abundance and status are virtually unknown. We conducted interviews with experienced hunters, and field surveys (linear and recce transects), to study the buffalo's distribution and ecology in the montane forests of Cross River State. General linear modelling indicated that the number of individuals varied significantly across survey areas and habitat types but not with the survey period, and there was no study area × study period interaction. Buffalo were found most commonly in mature and secondary forests. Given the species' scattered distribution, fragmentation of its habitat, and the relatively low numbers observed, Nigerian populations require a separate, regional categorization on the IUCN Red List

<i>WhatsApp</i> use among African international distance education (IDE) students: transferring, translating and transforming educational experiences

Much of the research on how social media is embedded into the educational practices of higher education students has a Western orientation. In concentrating on a case study of the varied ways in which African International Distance Education (IDE) students actively use social media to shape their learning experiences, we discuss an under-researched group. The paper draws on analysis of 1295 online questionnaires and 165 in-depth interviews with IDE students at UNISA, South Africa, one of the largest providers of IDE globally. WhatsApp emerges as ‘the’ key social media tool that opens up opportunities for IDE students to transfer, translate and transform their educational journey when studying ‘at a distance’. Although WhatsApp does provide a ‘space of opportunity’ for some students, this is framed through socio-technical marginalisation, itself a reflection of demographic legacies of inequality. Exploring social media practices though the case of African IDE students places these students centre stage and adds to the awareness of the multiple centres from which international education is practiced

An Estimate of the Incidence of Prostate Cancer in Africa: A Systematic Review and Meta-Analysis

Prostate cancer (PCa) is rated the second most common cancer and sixth leading cause of cancer deaths among men globally. Reports show that African men suffer disproportionately from PCa compared to men from other parts of the world. It is still quite difficult to accurately describe the burden of PCa in Africa due to poor cancer registration systems.We systematically reviewed the literature on prostate cancer in Africa and provided a continentwide incidence rate of PCa based on available data in the regio

Omics-based molecular techniques in oral pathology centred cancer: Prospect and challenges in Africa

: The completion of the human genome project and the accomplished milestones in the human proteome project; as well as the progress made so far in computational bioinformatics and “big data” processing have contributed immensely to individualized/personalized medicine in the developed world.At the dawn of precision medicine, various omics-based therapies and bioengineering can now be applied accurately for the diagnosis, prognosis, treatment, and risk stratifcation of cancer in a manner that was hitherto not thought possible. The widespread introduction of genomics and other omics-based approaches into the postgraduate training curriculum of diverse medical and dental specialties, including pathology has improved the profciency of practitioners in the use of novel molecular signatures in patient management. In addition, intricate details about disease disparity among diferent human populations are beginning to emerge. This would facilitate the use of tailor-made novel theranostic methods based on emerging molecular evidences

Les tumeurs des annexes de l’oeil a lome ocular adnexal tumors in lome.

Objectifs : Décrire les caractéristiques des tumeurs des annexes de l’oeil à Lomé Patients et Méthodes : Nous avons mené une étude rétrospective des patients suivis dans le service d’Ophtalmologie du CHU campus de Lomé, pour tumeur des annexes de l’oeil entre le 1er Janvier 2011 et le 31 Décembre 2013. Les caractéristiques cliniques et histologiques des tumeurs oculaires ont été analysées.Résultats : Sur la période, 27 cas de tumeurs des annexes de l’oeil ont été recensé, ce qui correspondait à une fréquence de 9 cas par an. L’âge moyen était de 30 ± 15,8 ans. Il existait une légère prédominance masculine avec un sex-ratio de 1,1. La sensation de corps étranger était le symptôme le plus fréquent avec 59,26% des cas. L’oeil droit était atteint dans 70,4% des cas. Les tumeurs conjonctivales étaient prédominantes avec 70,4% des cas. Sur les 27 cas de tumeurs des annexes, 19 ont été opéré soit un taux de chirurgie de 70,4%. Douze résultats d’histologies étaient disponibles dont 4 papillomes malpighiens.Conclusion : Les tumeurs des annexes de l’oeil intéressent le plus souvent la conjonctive, le type histologique le plus fréquent est le papillome malpighien. Il est important de prévenir ces types de tumeurs par le contrôle des facteurs de risques associés.Mots clés : Tumeurs, annexes, conjonctive, paupière, corps étranger, papillomemalpighien

A Report of Bethune-Cookman College NASA JOVE Projects

This document is the final report for the Joint Venture (JOVE) in Space Sciences, and describes the tasks, performed with the support of the contract. These tasks include work in: (1) interfacing microprocessor systems to high performance parallel interface chips, SCSI drive and memory, needed for the implementation of a Space Optical Data Recorder; (2) designing a digital interface architecture for a microprocessor controlled sensors monitoring unit for a NASA Jitter Attenuation and Dynamics Experiment (JADE) project; (3) developing an enhanced back-propagation training algorithm; (4) studying the effect of simulated spaceflight on Aortic Contractility; (5) developing a course in astronomy; and (6) improving internet access by running cables, and installing hubs in various places on the campus; and (7) researching the characteristics of Nd:YALO laser resonator
