Africapitalism: The marketisation of philanthrocapitalism and neoliberalism in African entrepreneurial philanthropy
Despite increased interests in marketisation of philanthrocapitalism research worldwide, the arguments emphasise ‘what’ instead of 'how’ and ‘why’ philanthropic philosophy happens across Africa. To address this gap, 51 Tony Elumelu Foundation participants’ narratives are focused on to draw on an Africapitalism framework highlighting chasms within and between western neoliberalism frameworks and philanthrocapitalism’s marketisation. By framing this paper using philanthrocapitalism discourse, the authors critically examined the activities of African philanthropists and the effects of their neoliberal adoption on recipients. Semi structured interview analysis produced three key ideologies demonstrating ‘what’, ‘how’ and ‘why’ philanthrocapitalism is marketised, namely utopianism and the illusion of a better socioeconomic tomorrow; neoliberalism and a culture of dominance; social investment and marketisation of benevolence. These thematic paradoxes were used to create an additional four-aspect Africapitalism framework contributing to ‘what’, ‘how’ and ‘why’ philanthrocapitalism is marketised in Africa, its impacts, challenges, and solutions. Contributions, limitations and implications for research are articulate
GEOPHYSICAL INVESTIGATION OF PROPOSED DAM SITE ALOMG RIVER ADUNIN, OGBOMOSO, SOUTHWESTERN NIGERIA.
ABSTRACT
Dams are vital structures that store water for consumption, irrigation, electricity production and industrial purposes.The design and construction is very important to prevent the collapse of the structure .Thirty (30) Vertical Electrical Sounding points were investigated. Very Low Frequency profiling at 5m inter station along five profiles were carried out. The interpretation of geophysical data were achieved using the following software; Res 2D, Win Resist, Surfer 11, Arc GIS 3.3 and Excel. Six resistivity sounding curve types were obtained from the study area and these are the H, HA , KH, HKH, and KHA curves. The geologic sequence beneath the study area is composed of top soil, weathered basement, fractured basement, and fresh basement. The topsoil is composed of clayey-sandy and sandy-lateritic hard crust with resistivity values ranging from 339-1971 ohm-m and thickness of 0.7-1.3 m. The weathered basement resistivity is within the range of 98-3026 ohm-m and thickness value of 0.3-7.0m.The fractured basement layer resistivity values vary from 163–4049 ohm-m while its thickness ranges from 2.7 to 17m. Fresh basement has resistivity value range of 228 to14793 ohm-m.
The bedrock is highly fractured beneath the river axis and extended toward the left abutment while fresh basement is closer to the surface at the right abutment.The fractures beneath the proposed dam axis may pose serious threat to the dam in term of future seepage. The dam should be shifted toward the right abutment by 20m and excavation should be made up to depth of about 5m, the materials so removed could be used for the construction of the embankment and the filter materials
Inflammation causes remodeling of mitochondrial cytochrome c oxidase mediated by the bifunctional gene C15orf48
Dysregulated mitochondrial function is a hallmark of immune-mediated inflammatory diseases. Cytochrome c oxidase (CcO), which mediates the rate-limiting step in mitochondrial respiration, is remodeled during development and in response to changes of oxygen availability, but there has been little study of CcO remodeling during inflammation. Here, we describe an elegant molecular switch mediated by the bifunctional transcript C15orf48, which orchestrates the substitution of the CcO subunit NDUFA4 by its paralog C15ORF48 in primary macrophages. Expression of C15orf48 is a conserved response to inflammatory signals and occurs in many immune-related pathologies. In rheumatoid arthritis, C15orf48 mRNA is elevated in peripheral monocytes and proinflammatory synovial tissue macrophages, and its expression positively correlates with disease severity and declines in remission. C15orf48 is also expressed by pathogenic macrophages in severe coronavirus disease 2019 (COVID-19). Study of a rare metabolic disease syndrome provides evidence that loss of the NDUFA4 subunit supports proinflammatory macrophage functions

Efficient and safe correction of hemophilia A by lentiviral vector-transduced BOECs in an implantable device
Hemophilia A (HA) is a rare bleeding disorder caused by deficiency/dysfunction of the FVIII protein. As current therapies based on frequent FVIII infusions are not a definitive cure, long-term expression of FVIII in endothelial cells through lentiviral vector (LV)-mediated gene transfer holds the promise of a one-time treatment. Thus, here we sought to determine whether LV-corrected blood outgrowth endothelial cells (BOECs) implanted through a prevascularized medical device (Cell Pouch™) would rescue the bleeding phenotype of HA mice. To this end, BOECs from HA patients and healthy donors were isolated, expanded and transduced with an LV carrying FVIII driven by an endothelial-specific promoter employing GMP-like procedures. FVIII-corrected HA-BOECs were either directly transplanted into the peritoneal cavity or injected into a Cell Pouch™ implanted subcutaneously in NSG-HA mice. In both cases, FVIII secretion sufficient to improve the mouse bleeding phenotype. Indeed, FVIII-corrected HA-BOECs reached a relatively short-term clinically relevant engraftment being detected up to 16 weeks after transplantation, and their genomic integration profile did not show enrichment for oncogenes, confirming the process safety. Overall, this is the first pre-clinical study showing the safety and feasibility of transplantation of GMP-like produced LV-corrected BOECs within an implantable device for the long-term treatment of HA

Imagining an Imperial Modernity: Universities and the West African Roots of Colonial Development
© 2016 Informa UK Limited, trading as Taylor & Francis GroupThis article takes the formation and work of the ‘Elliot’ Commission on Higher Education in West Africa (1943–45) to reconsider the roots of British colonial development. Late colonial universities were major development projects, although they have rarely been considered as such. Focusing particularly on the Nigerian experience and the controversy over Yaba Higher College (founded 1934), the article contends that late colonial plans for universities were not produced in Britain and then exported to West African colonies. Rather, they were formed through interactions between agendas and ideas with roots in West Africa, Britain and elsewhere. These debates exhibited asymmetries of power but produced some consensus about university development. African and British actors conceptualised modern education by combining their local concerns with a variety of supra-local geographical frames for development, which included the British Empire and the individual colony. The British Empire did not in this case forestall development, but shaped the ways in which development was conceived
Pseudomonas aeruginosa mutants defective in glucose uptake have pleiotropic phenotype and altered virulence in non-mammal infection models
Pseudomonas spp. are endowed with a complex pathway for glucose uptake that relies on multiple transporters. In this work we report the construction and characterization of Pseudomonas aeruginosa single and multiple mutants with unmarked deletions of genes encoding outer membrane (OM) and inner membrane (IM) proteins involved in glucose uptake. We found that a triple \u394gltKGF \u394gntP \u394kguT mutant lacking all known IM transporters (named GUN for Glucose Uptake Null) is unable to grow on glucose as unique carbon source. More than 500 genes controlling both metabolic functions and virulence traits show differential expression in GUN relative to the parental strain. Consistent with transcriptomic data, the GUN mutant displays a pleiotropic phenotype. Notably, the genome-wide transcriptional profile and most phenotypic traits differ between the GUN mutant and the wild type strain irrespective of the presence of glucose, suggesting that the investigated genes may have additional roles besides glucose transport. Finally, mutants carrying single or multiple deletions in the glucose uptake genes showed attenuated virulence relative to the wild type strain in Galleria mellonella, but not in Caenorhabditis elegans infection model, supporting the notion that metabolic functions may deeply impact P. aeruginosa adaptation to specific environments found inside the host
