    This study was conducted in the Iraqi Kurdistan region in January 2014 to determine the individual leaf area of oleander (Nerium oleander L.) by easy, accurate, inexpensive, and nondestructive method. Simple, multiple and exponential regression analyses were used by length (L) and width (W) and their combinations as independent variables and with leaf area as dependent variable to determine more accurate models (high coefficient of determination and less MSE). The results showed that the best fitting models that show more accurate estimation of oleander leaf area, compared to other models, were the simple linear regression that depends on length multiple width for Koya and Erbil cities and the total leaves of the two cities plants. On the other hand, the best fitting multiple linear equations were those which depend on square length and square width for Koya city and the total leaves of the two cities plants, whereas for Erbil city the best model was that depends on leaves with square length and width. Multiple linear regressions were the more accurate among the models, followed by simple linear regression, whereas the exponential model had the lowest accuracy. All coefficients of regressions values were found to be significant at the P < 0.0001 level

    Introduction: In inflammatory joint disease, such as osteoarthritis (OA), there is an increased level of proinflammatory cytokines, such as interleukin (IL)-1ÎČ. These cytokines stimulate the production of matrix metalloproteinases (MMPs), which leads to the degradation of the cartilage extracellular matrix and the loss of key structural components such as sulphated glycosaminoglycan (sGAG) and collagen II. The aim of this study was to examine the therapeutic potential of n-3 polyunsaturated fatty acids (PUFAs) in an in vitro model of cartilage inflammation. Methods: Two specific n-3 compounds were tested, namely, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), each at 0.1, 1 and 10 ÎŒM. Full thickness bovine cartilage explants, 5 mm in diameter, were cultured for 5 days with or without IL-1ÎČ and in the presence or absence of each n-3 compound. The media were replaced every 24 hours and assayed for sGAG content using the 1,9-dimethylmethylene blue (DMB) method. Chondrocyte viability was determined at the end of the culture period using fluorescence microscopy to visualise cells labelled with calcein AM and ethidium homodimer. Results: Treatment with IL-1ÎČ (10 ng.ml-1) produced a large increase in sGAG release compared to untreated controls, but with no effect on cell viability, which was maintained above 80% for all treatments. In the absence of IL-1ÎČ, both n-3 compounds induced a mild catabolic response with increased loss of sGAG, particularly at 10 ÎŒM. By contrast, in the presence of IL-1ÎČ, both EPA and DHA at 0.1 and 1 ÎŒM significantly reduced IL-1ÎČ-mediated sGAG loss. The efficacy of the EPA treatment was maintained at approximately 75% throughout the 5-day period. However, at the same concentrations, the efficacy of DHA, although initially greater, reduced to approximately half that of EPA after 5 days. For both EPA and DHA, the highest dose of 10 ÎŒM was less effective. Conclusions: The results support the hypothesis that n-3 compounds are anti-inflammatory through competitive inhibition of the arachidonic acid oxidation pathway. The efficacy of these compounds is likely to be even greater at more physiological levels of IL-1ÎČ. Thus we suggest that n-3 PUFAs, particularly EPA, have exciting therapeutic potential for preventing cartilage degradation associated with chronic inflammatory joint disease

    Topiramate-Induced Modulation of Hepatic Molecular Mechanisms: An Aspect for Its Anti-Insulin Resistant Effect

    Topiramate is an antiepileptic drug known to ameliorate insulin resistance besides reducing body weight. Albeit liver plays a fundamental role in regulation of overall insulin resistance, yet the effect of topiramate on this organ is controversial and is not fully investigated. The current work aimed to study the potential hepatic molecular mechanistic cassette of the anti-insulin resistance effect of topiramate. To this end, male Wistar rats were fed high fat/high fructose diet (HFFD) for 10 weeks to induce obese, insulin resistant, hyperglycemic animals, but with no overt diabetes. Two HFFD-groups received oral topiramate, 40 or 100 mg/kg, for two weeks. Topiramate, on the hepatic molecular level, has opposed the high fat/high fructose diet effect, where it significantly increased adiponectin receptors, GLUT2, and tyrosine kinase activity, while decreased insulin receptor isoforms. Besides, it improved the altered glucose homeostasis and lipid profile, lowered the ALT level, caused subtle, yet significant decrease in TNF-α, and boosted adiponectin in a dose dependent manner. Moreover, topiramate decreased liver weight/, visceral fat weight/, and epididymal fat weight/body weight ratios. The study proved that insulin-resistance has an effect on hepatic molecular level and that the topiramate-mediated insulin sensitivity is ensued partly by modulation of hepatic insulin receptor isoforms, activation of tyrosine kinase, induction of GLUT2 and elevation of adiponectin receptors, as well as their ligand, adiponectin, besides its known improving effect on glucose tolerance and lipid homeostasis

    This cross-sectional survey study conducted between May and August 2017 on Arabic-speaking refugees resettled in Australia examined factors associated with willingness to donate organs. Of the 239 respondents, those who expressed greater willingness to donate organs and tissues were more likely to: (a) be Christians; (b) have obtained information from healthcare professionals (HCPs); (c) have higher organ and tissue donation (OTD) knowledge; (d) have a positive attitude towards OTD; and (e) have high English language acculturation levels. Nevertheless, after controlling for English language usage and religion, having a positive attitude towards OTD and receiving information from HCPs emerged as independent predictors of willingness to donate, underscoring the importance of educational interventions by HCPs

    UN/RE-CONSTRUCTING THE AGRARIAN DREAM: GOING BACK-TO-THE-LAND WITH AN ORGANIC MARKETING CO-OPERATIVE IN SOUTH-CENTRAL PENNSYLVANIA, USA

    No full text
    This paper employs a cultural-economic approach to understanding the labour model strategies employed by an organic marketing co-operative in a rural community of south-central Pennsylvania. The co-operative is composed of self-described 'back-to-the-landers', who are motivated by an agrarian dream of a better quality of life, making a living off the land and contributing to the environmental sustainability of farming. Organic agriculture as a technical practice with a lucrative market holds the promise of realising these dreams, and the co-operative functions as an alternative food network that delivers organic produce to a regional market. The members of the co-operative employ a diversity of labour strategies, some of which reproduce the labour processes and outcomes of the conventional food systems, and others which (sometimes simultaneously) configure new social and economic relations with farm workers.
