Significance of myocardial tenascin-C expression in left ventricular remodelling and long-term outcome in patients with dilated cardiomyopathy

Aim Dilated cardiomyopathy (DCM) has a variety of causes, and no useful approach to predict left ventricular (LV) remodelling and long-term outcome has yet been established. Myocardial tenascin-C (TNC) is known to appear under pathological conditions, possibly to regulate cardiac remodelling. The aim of this study was to clarify the significance of myocardial TNC expression in LV remodelling and the long-term outcome in DCM. Methods and results One hundred and twenty-three consecutive DCM patients who underwent endomyocardial biopsy for initial diagnosis were studied. Expression of TNC in biopsy sections was analysed immunohistochemically to quantify the ratio of the TNC-positive area to the whole myocardial tissue area (TNC area). Clinical parameters associated with TNC area were investigated. The patients were divided into two groups based on receiver operating characteristic analysis of TNC area to predict death: high TNC group with TNC area ≥2.3% (22 patients) and low TNC group with TNC area <2.3% (101 patients). High TNC was associated with diabetes mellitus. Comparing echocardiographic findings between before and 9 months after endomyocardial biopsy, the low TNC group was associated with decreased LV end-diastolic diameter and increased LV ejection fraction, whereas the high TNC group was not. Survival analysis revealed a worse outcome in the high TNC group than in the low TNC group (P < 0.001). Multivariable Cox regression analysis revealed that TNC area was independently associated with poor outcome (HR = 1.347, P = 0.032). Conclusions Increased myocardial TNC expression was associated with worse LV remodeling and long-term outcome in DCM

Developing Peacebuilding and Entrepreneurship Education to Empower Women and Youth: Sustainable Development Approaches for Southeast Nigeria

This study investigated the relationship between entrepreneurship education and peacebuilding. This intersection plays a critical role in empowering women and youth in Southeast Nigeria. Giving women and young people skills in entrepreneurship and peacebuilding can promote social cohesion and economic resilience in light of the socioeconomic and political challenges facing the region, such as poverty, unemployment, and conflict. While addressing the particular difficulties faced by women and youth in southeast Nigeria, the paper emphasised the importance of education in establishing a sustainable path for development and peace. This study employed a mixed-methods approach, integrating both quantitative and qualitative techniques. This simple mixed-methods design allows for an effective analysis of both the measurable outcomes and personal experiences. The study also found that the region can move toward long-term peace and development if these vulnerable groups are given the skills necessary to settle disputes and generate economic opportunities. A comprehensive approach that incorporates entrepreneurship and peace education into regional and national development frameworks is crucial, as the study\u27s recommendations for policy reforms highlight

The experience of living with vitiligo in Nigeria:A participatory Interpretative Phenomenological Analysis

Vitiligo is a visible depigmenting skin condition, particularly noticeable on Black skin. There is widespreadmisunderstanding of the condition. Using a participatory form of Interpretative Phenomenological Analysis(IPA), we conducted eight semi-structured interviews with Nigerians living with vitiligo. Participantsdescribed their initial attempts to understand the condition, which typically drew on both traditional illnessbeliefs, religious influences, and the biomedical disease model. All participants reported experiencing markedstigmatization and discrimination. Participants experienced distress associated with thoughts about the personalmeaning of the disease including its impact on their appearance and from concerns about anticipatedand direct discrimination. Despite the wide-ranging impact, the participants’ narratives also contained referencesto the development of strategies that maintained wellbeing. This study provides valuable insights intothe role of faith and traditional beliefs in both the experience and management of vitiligo in Nigeria. Theseinsights can be used to develop individual and community interventions

Abstract B047: Biochemical parameters of prostate cancer patients in Nigeria

The screening of biochemical parameters of cancer patients and their development into reliable and specific diagnostic and prognostic biomarkers has been reported in several studies. The biochemical signature of prostate cancer patients in Nigeria may vary from others and can serve as important leads in discovery of new biomarkers for the disease. This will ultimately provide more information on the specific causes and prognosis of the disease as well as improve its diagnosis and management. This study examined some biochemical parameters including alanine transaminase (ALT), alkaline phosphatase (ALP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TRIG), reduced glutathione (GSH), lipid peroxidation and peroxidase (POD) in the plasma of prostate cancer patients and controls. The data obtained indicate that there were no significant differences in the ALT, LDL, HDL, and POD while ALP and TRIG were significantly increased. Also, there was a significant reduction in GSH. This indicates the possible implication of ALP, TRIG, and GSH in prostate cancer disease in Nigeria and their potential to be further developed into diagnostic and prognostic biomarkers

PHOENIX DACTYLIFERA FRUIT EXTRACT AMELIORATES ALTERED BIOCHEMICAL PARAMETERS IN STREPTOZOTOCIN-INDUCED DIABETES MELLITUS ALBINO RATS

Objective: Consistent projections have indicated a steady increase in the global burden of diabetes mellitus. Given the increased cost in conventional management of the condition in addition to reported side effects and cost of orthodox management, attention is shifting to the use of alternative methods such as plants materials with dual benefits as food and medicine. Thus, this study was designed to investigate the effect of date palm fruit on some biochemical parameters in streptozotocin-induced wistar rats. Methods: Animals were divided into 5 groups of 6 rats each (I as normal control, II as diabetic control and 3-5 as extract-treated groups) maintained for 14 d. At the end of the treatment, the animals were fasted overnight, then sacrificed and blood samples collected for analysis of biochemical parameters (including blood glucose, blood lipids and enzymes). Results: The results show that treatment of diabetic animals with extract of date palm fruit show a significant (P&lt;0.05) reduction in glucose levels in groups II–V compared to group I. Similar positive effects were observed in the levels of lipids and enzymes in treated groups compared to diabetic control group II. A GC-MS analysis of the fraction of the fruit extract revealed some bioactive compounds that may be responsible for the effects exhibited in the study. Conclusion: These findings which demonstrate the ameliorative effect on hyperglycemia and hyperlipidemia, further support the use of date palm fruit as a nutraceutical agent

Abstract B048: Androgen metabolism and incidence of prostate cancer in Nigeria

The risk of prostate cancer among blacks, especially of Nigerian descent, is higher than other races. This could be attributed to biologic and genetic variability. The role of androgen metabolism in prognosis of prostate cancer has been delineated and reported. One of the enzymes involved in androgen metabolism is CYP3A4, which has not been studied in Nigerian men afflicted with prostate cancer. Racial differences in this functional gene may contribute to variations in incidence of prostate cancer across ethnic divides. Therefore, identifying a diagnostic and prognostic biomarker such as CYP3A4 polymorphism for prostate cancer in black men will improve the treatment and management of the disease. In this study, we investigated the genotypes of CYP3A4 of prostate cancer patients from Nigeria for possible correlation to the high incidence of the disease in Nigerian men. The results obtained showed a preponderance of the GG genotypes, which indicates a possible correlation between this genotype of CYP3A4 and higher risk of prostate cancer among Nigerian men

Identification and design principles of low hole effective mass p-type transparent conducting oxides

The development of high-performance transparent conducting oxides is critical to many technologies from transparent electronics to solar cells. Whereas n-type transparent conducting oxides are present in many devices, their p-type counterparts are not largely commercialized, as they exhibit much lower carrier mobilities due to the large hole effective masses of most oxides. Here we conduct a high-throughput computational search on thousands of binary and ternary oxides and identify several highly promising compounds displaying exceptionally low hole effective masses (up to an order of magnitude lower than state-of-the-art p-type transparent conducting oxides), as well as wide band gaps. In addition to the discovery of specific compounds, the chemical rationalization of our findings opens new directions, beyond current Cu-based chemistries, for the design and development of future p-type transparent conducting oxides.United States.
