    Poverty among rural women in Nigeria hinders the economic and socialwellbeing of families. Alleviating such poverty is therefore a major issue for national survival. This study investigated the strategies for inculcating Home Economics based life (survival) skills among rural women as a panacea for poverty alleviation. The study was a descriptive survey that was based on two research questions. From a population of 1,815 respondents, purposive sampling was used to select a sample of 253 respondents (40 home economics teachers and 213 secretaries of registered women cooperative societies in ten Local government Areas of Anambra State. A questionnaire titled “Inculcating Home Economics-Based Life Skills for Poverty Alleviation (IHELSPA)” was used for data collection. Data was analysed using mean ratings. The findings included that several Home Economics based life skills could be inculcated among the rural women using a range of networking approaches. Among the recommendations was that Government and non-governmental organizations should mobilize communities, youth groups, and other private sector organizations to network and contribute in building the capacities of rural women in Home Economics based life (survival) skill

    A subspace-based resolution-enhancing image reconstruction method for few-view differential phase-contrast tomography

    It is well known that properly designed image reconstruction methods can facilitate reductions in imaging doses and data-acquisition times in tomographic imaging. The ability to do so is particularly important for emerging modalities, such as differential x-ray phase-contrast tomography (D-XPCT), which are currently limited by these factors. An important application of D-XPCT is high-resolution imaging of biomedical samples. However, reconstructing high-resolution images from few-view tomographic measurements remains a challenging task due to the high-frequency information loss caused by data incompleteness. In this work, a subspace-based reconstruction strategy is proposed and investigated for use in few-view D-XPCT image reconstruction. By adopting a two-step approach, the proposed method can simultaneously recover high-frequency details within a certain region of interest while suppressing noise and/or artifacts globally. The proposed method is investigated by the use of few-view experimental data acquired by an edge-illumination D-XPCT scanner

    A joint-reconstruction approach for single-shot edge illumination x-ray phase-contrast tomography

    Get PDF
    Edge illumination X-ray phase-contrast tomography (EIXPCT) is an imaging technique that estimates the spatially variant X-ray refractive index and absorption distribution within an object while seeking to circumvent the limitations of previous benchtop implementations of X-ray phase-contrast tomography. As with gratingor analyzer-based methods, conventional image reconstruction methods for EIXPCT require that two or more images be acquired at each tomographic view angle. This requirement leads to increased data acquisition times, hindering in vivo applications. To circumvent these limitations, a joint reconstruction (JR) approach is proposed that concurrently produces estimates of the refractive index and absorption distributions from a tomographic data set containing only a single image per tomographic view angle. The JR reconstruction method solves a nonlinear optimization problem by use of a novel iterative gradient-based algorithm. The JR method is demonstrated in both computer-simulated and experimental EIXPCT studies

    DNA methylation governs the dynamic regulation of inflammation by apoptotic cells during efferocytosis

    Efficient clearance of apoptotic cells (AC) is pivotal in preventing autoimmunity and is a potent immunosuppressive stimulus. However, activation of cells prior to apoptosis abolishes their immunoregulatory properties. Here we show using the antigen-induced model of arthritis that the degree of DNA methylation within AC confers their immunomodulatory plasticity. DNA isolated from resting and activated AC mimicked their respective immune effects. Demethylation of DNA abrogated the protective effect of AC whereas remethylation of AC DNA reversed the effects of activation and restored the ability to inhibit inflammation. Disease suppression or lack thereof was associated with TGFβ and IL-6 production respectively. Apoptotic CD4+ T cells from patients with rheumatoid arthritis and systemic lupus erythematosus were demethylated compared to healthy controls and favoured production of IL-6 when cultured with healthy macrophages, in contrast to the TGFβ produced in response to healthy AC. Our data implicate AC DNA methylation as the molecular switch that imprints their regulatory properties

    Comparison of data-acquisition designs for single-shot edge-illumination X-ray phase-contrast tomography

    Get PDF
    Edge-illumination X-ray phase-contrast tomography (EIXPCT) is an emerging technique that enables practical phase-contrast imaging with laboratory-based X-ray sources. A joint reconstruction method was proposed for reconstructing EIXPCT images, enabling novel flexible data-acquisition designs. However, only limited efforts have been devoted to optimizing data-acquisition designs for use with the joint reconstruction method. In this study, several promising designs are introduced, such as the constant aperture position (CAP) strategy and the alternating aperture position (AAP) strategy covering different angular ranges. In computer-simulation studies, these designs are analyzed and compared. Experimental data are employed to test the designs in real-world applications. All candidate designs are also compared for their implementation complexity. The tradeoff between data-acquisition time and image quality is discussed
