    Optimizing community-driven development through sage tradition in Cameroon

    Powering community development requires a re-invention of traditional authority. This paper interrogates this proposition: how does sage tradition engender social resilience and what is the impact of traditional authority on the modern governance architecture? Sage tradition construed culturally as elder-led authority is anchored on wisdom and respect for elders—a pivotal asset in community development transactions. Informed by indigenous knowledge, social capital and asset-based concepts, an empirical account of strategic leadership by the elderly is proffered, uncovering indigenous governance in the North West Region, Cameroon. A pyramidal power structure validates village elders as key players in advancing social justice. They offer counsel and arbitrate in community affairs and mobilise community members for infrastructure provision—community halls, equipping schools, digging roads, building bridges and supply of fresh water. Though elder esteemed traditions prove perfunctory, findings show communities are benefiting from the accumulated, incremental cultural assets factored into local development. The paper concludes that thriving cultural assets should be amalgamated through a policy drive that taps into the utility of traditional authority, in synergy with modern state institutions to bolster social development, address poverty and social inequality

    <p>Abstract</p> <p>Background</p> <p>A beneficial effect of gentamicin supplemented mesh material on tissue integration is known. To further elucidate the interaction of collagen and MMP-2 in chronic foreign body reaction and to determine the significance of the MMP-2-specific regulatory element (RE-1) that is known to mediate 80% of the MMP-2 promoter activity, the spatial and temporal transcriptional regulation of the MMP-2 gene was analyzed at the cellular level.</p> <p>Methods</p> <p>A PVDF mesh material was surface modified by plasma-induced graft polymerization of acrylic acid (PVDF+PAAc). Three different gentamicin concentrations were bound to the provided active sites of the grafted mesh surfaces (2, 5 and 8 ÎĽg/mg). 75 male transgenic MMP-2/LacZ mice harbouring the LacZ reporter gene under control of MMP-2 regulatory sequence -1241/+423, excluding the RE-1 were randomized to five groups. Bilateral of the abdominal midline one of the five different meshes was implanted subcutaneously in each animal. MMP-2 gene transcription (anti-Ăź-galactosidase staining) and MMP-2 protein expression (anti-MMP-2 staining) were analyzed semiquantitatively by immunohistochemistry 7, 21 and 90 days after mesh implantation. The collagen type I/III ratio was analyzed by cross polarization microscopy to determine the quality of mesh integration.</p> <p>Results</p> <p>The perifilamentary Ăź-galactosidase expression as well as the collagen type I/III ratio increased up to the 90<sup>th </sup>day for all mesh modifications, whereas no significant changes could be observed for MMP-2 protein expression between days 21 and 90. Both the 5 and 8 ÎĽg/mg gentamicin group showed significantly reduced levels of Ăź-galactosidase expression and MMP-2 positive stained cells when compared to the PVDF group on day 7, 21 and 90 respectively (5 ÎĽg/mg: p < 0.05 each; 8 ÎĽg/mg: p < 0.05 each). Though the type I/III collagen ratio increased over time for all mesh modifications significant differences to the PVDF mesh were only detected for the 8 ÎĽg/mg group at all 3 time points (p < 0.05 each).</p> <p>Conclusions</p> <p>Our current data indicate that lack of RE-1 is correlated with increased mesh induced MMP-2-gene expression for coated as well as for non-coated mesh materials. Gentamicin coating reduced MMP-2 transcription and protein expression. For the 8 ÎĽg/mg group this effect is associated with an increased type I/III collagen ratio. These findings suggest that gentamicin is beneficial for tissue integration after mesh implantation, which possibly is mediated via RE-1.</p
