    Volatile fatty acids production in ruminants and the role of monocarboxylate transporters: A review

    Get PDF
    Monocarboxylates commonly referred to as short-chain fatty acids (SCFAs) are metabolized to different extents by the epithelium of the gastrointestinal tract. They are absorbed along different segments of the gastrointestinal tract and constitute a significant amount of energy in ruminants. Monocarboxylates play a central role in cellular metabolism and metabolic communication between tissues. Essential to these roles is their rapid transport across the plasma membrane, which is catalyzed by a recently identified family of proton-linked monocarboxylate transporters (MCTs). Monocarboxylate transporter-1 and 4 have been shown to interact specifically with OX-47 (CD147), a member of the immunoglobulin superfamily with a single transmembrane helix. This interaction appears to assist MCT expression at the cell surface. Despite the importance of short-chain fatty acids in being the main energy source in ruminant animals, the mechanism of SCFAs transport and absorption is still not fully studied. The aim of this review is to critically discuss short-chain fatty acids production and the functional role of monocarboxylate transporters in relation to the transport and absorption of these nutrients along the gastrointestinal tract of ruminants. Two major functions of monocarboxylate transporter proteins, namely the facilitation of the absorption of SCFAs in the gastrointestinal tract and the regulation of cell pH in skeletal muscles, are clearly very important for physiological homeostasis, animal welfare and productivity.Key words: Ruminants, monocarboxylates, monocarboxylate transporters, CD147

    The usage and reuse of waste tyre rubber in concrete production can cut down the use of raw materials which contributes to economic efficiency and sustainable development of the construction industry. This study is directed at assessing the effects of using the Tyre Derived Aggregate (TDA) as a substitute for coarse aggregate in concrete. A sum of eighty-six square cubes of 100 mm was cast and cured in fresh water for up to 28 days. Setting times, consistency and soundness tests were carried out on cement paste. However, slump, compressive strength and durability (i.e. water absorption) tests were carried out on the concrete. The results unveiled that the physical characteristics of cement considered fulfilled BS EN 196-3 (1995), and the slump of fresh concrete decreased as the percentage of TDA content stepped up. The water absorption raised, while the density of concrete made with TDA decreased as the percentage of TDA content stepped up. However, the strength of TDA-concrete increased as the curing age increased, and it decreased as the portion of TDA content raised. Nevertheless, the strength at 0%, 5% and 10% were 23, 21.67 and 18.33 N/mm2 respectively. However, the strength of TDA-concrete made with 0 % TDA and 5 % TDA subjected to different temperatures decreased as the temperature increased, however, even at 500C the strength of concrete made with 5% TDA was found to be 20.5 N/mm2 which is within the target compressive strength. It was concluded that the usage of TDA content in the production of concrete should not be greater than 5 % for better performance

    In this paper, a non-linear model with three control parameters for household of malaria has been study. The disease free equilibrium is obtained and the basic reproduction number is computed using the next generation matrix. We carry out cost evaluation of the model to optimize the cost of the intervention in the objective functional using Pontryagins’s Maximum Principle (PMP). We apply the optimal control strategy to investigate and analyze the optimal cost for controlling the transmission of malaria using treated bednets, treatment and indoor residual spray as parameters. Numerical simulation has been carry out using Runge-Kutta of order four to calculate the incremental cost effectiveness ratio () for the implementation of various combinations of the parameters to determine the most cost effective strategy that check the spread of the disease. Our findings show that the most cost-effective strategy to check the spread of malaria is strategy F (the combination of treatment of infected individuals and indoor residual spray parameters).

    Contemporary Discourses in Qualitative Research: Lessons for Health Research in Nigeria

    Get PDF
    Quantitative research has permeated and dominated health research in Nigeria. One of the oldest and the most commonly used quantitative research designs are KAP (knowledge, attitude and practice) surveys. Although KAP surveys are important approaches to assessing distribution of community knowledge in large-scale projects, such surveys are often inundated by challenges, especially with regard to accurate measurement and understanding of social construction of health and illness. This paper examines contemporary ontological, epistemological, axiological and methodological discourses in the qualitative research approach and argues for adequate utilisation of the qualitative approach in health research in Nigeria. The qualitative approach deepens understanding of cultural milieu regarding health beliefs and socio-cultural issues surrounding medical therapy, as well as health seeking behaviour. Therefore, this paperargues for a more participatory research methodology in the understanding of health, illness and disease in Nigeria. Some case studies of qualitative research from Nigeria and abroad were reviewed from which health researchers (clinical managers and health social scientists and public health experts) could learn. The paper is thus a contribution to the ongoing discourses in global qualitative health research.Keywords: Qualitative research; quantitative research; ontology; epistemology; developing countries; Nigeria

    Objectives: Human Immunodeficiency Virus (HIV) remains a public health issue with more than 25 million deaths since 1990. Â As of 2019, Nigeria has a national prevalence of 1.4% among 15- 49 years and about 1.9 million people living with HIV, according to the Joint United Nations Programme on HIV/AIDS. This study assessed the factors responsible for unsuppressed viral load among patients accessing care at Federal Medical Centre HIV Clinic in Abeokuta, southwest Nigeria. Methods: The study design was descriptive cross-sectional. Data was collected using the qualitative method; an In-depth interview was conducted among 20 virally unsuppressed HIV patients currently on Antiretroviral Therapy (ART) at Federal Medical Centre Abeokuta. The participants were purposively selected. The data were analyzed using thematic analysis. Results: Although almost all the participants were aware of HIV, their knowledge of HIV was inadequate. Non- adherence to drugs, side effects of medications, the psychological effects of the disease, forgetfulness, and combination of anti-retroviral drugs with local herbs and alcohol were the associated factors of viral non-suppression among the patients. Conclusion: Scaling up psychological care services using Short Message Services (SMS) to improve viral suppression is, therefore, strongly recommended

    The impacts of scientific research by an individual or institution are measured using various bibliometric indices such as the h-index and citations index among others. Objective: The present study assessed the global impacts of scientific publications by academic staff of the College of Medical Sciences, University of Maiduguri (CMS-UNIMAID) using selected bibliometric indices. Methodology: The data (demographic data, research experience, and the number of publications) of the 202 academic staff of College of Medical Sciences CMS-UNIMAID were obtained from the records submitted for the 2019/2020 annual appraisal. The h-index, citations index (CI), number of documents (ND), RG score, research interest (RI), citation/item, and citation/year of the staff were extracted from Google Scholar, Publons, ResearchGate, and Scopus using th authors search until 25 December 2020. Staff and publication online visibilities were determined. Descriptive statistics were prepared for all records obtained and subjected to appropriate inferential statistics. Results: The mean age and research experience of the staff were 45.4±9.2 and 13.9±9.6 years, respectively. The majority (p<0.05) of the staff were male (85.1%), had a PhD/Professional Fellowship (61.4%), and were senior academic staff (53.5%). Atotal of 4940 publication entries were submitted for the appraisal. Only 2.5% of the staff were visible on all platforms with staff online visibility of 63.9, 55.5, 15.8, and 5.0% (p<0.05) on Scopus, ResearchGate, Google Scholar, and Publons, respectively. Male staff (68.0%) were more visible (p<0.05) than their female counterparts (40.0%) on Scopus while senior academic staff were more visible (p<0.05) than junior academic staff on all platforms except Publons. Publication online visibility was highest (p<0.05) in Google Scholar (78.4%) and ResearchGate (65.9%) than Publons (28.0%) and Scopus (25.1%). The mean h-index, CI, and ND were 8.3±1.1, 401.8±97.8, and 36.2±4.9, respectively on Google Scholar and 5.0±0.4, 166.4±25.6 and 9.0±0.9, on ResearchGate. Publons showed means h-index, CI, and ND of 5.0±0.3, 77.2±13.7, and 25.6±2.1, respectively while Scopus showed 4.0±1.6, 144.4±95.3, and 14.5±6.2, respectively. In addition, the means RG score and RI were 10.0±0.7 and 113.1±15.4, respectively while the means citation/item and citation/year were 3.9±1.7 and 10.7±6.8, respectively. Conclusions: Low bibliometric indices indicate poor global impact of scientific publications from CMS-UNIMAID. Concerted efforts are required to improve the quality of research and publication through adequate funding, infrastructure, and mentorship among others

    The haemoglobin regeneration potential of fermented and unfermented Telfaira occidentalis and Gnetum africanum leaves in iron deficient albino rats

    Get PDF
    The effect of 10% supplementation of fermented and unfermented Telfaira occidentalis and Gnetum africanum leaves for 21 days on haemoglobin-iron, haematological parameters and serum ferritin was investigated to determined if the leaves could replenish haemoglobin in iron deficient rats. Iron deficiency significantly (p<0.05) decreased the relative weight gain, haemoglobin-iron, serum ferritin, haemoglobin (Hb), and mean corpuscular haemoglobin concentration (MCHC), when compared to the iron sufficient control rats. Rats fed with T. occidentalis had a significantly (p<0.05) increased serum ferritin compared to those fed with G. africanum leaves. The levels of haematological parameters of rats in the iron deficient group were not significantly (p>0.05) different from the iron sufficient and leaves supplemented groups. However, haemoglobin concentration of rats on iron sufficient diet, fermented and unfermented T. occidentalis leaves and those treated with FeSO4 were significantly (p<0.05) higher than that of rats in the iron deficient, fermented and unfermented G. africanum groups respectively. Percentage change in Haemoglobin-iron was lower for rats supplemented with the fermented forms of both leaves. This study shows that T. occidentalis has a significant (p<0.05) haemoglobin regeneration potential compared to G. africanum, and fermentation did not significantly (p>0.05) enhance the haemoglobin regeneration potential of both leaves.© 2015 International Formulae Group.
