The compounds XA and 4HD are known to have anti-inflammatory and anti-diabetic functions although their beneficial effect on vascular disease is not clear. Atherosclerosis induced by lifestyle-related diseases such as obesity and hypertension is a serious vascular disease in which endothelial injury plays a major pathogenic role. Therefore, the healing of endothelial injury is considered important in preventing atherosclerosis. The present study examined whether XA and 4HD promote the wound healing of cultured porcine vascular endothelial cells (ECs) and analyzed the molecular mechanisms of their effect. Both compounds promoted endothelial wound healing, induced nitric oxide (NO) production, and increased heme oxygenase-1 (HO-1) expression as well as the phosphorylation level of endothelial NO synthase (eNOS). The wound healing promoted by these compounds was inhibited by pretreatment with the NOS inhibitor L-NMMA and HO-1 inhibitor ZnPPIX, respectively. ZnPPIX inhibited the phosphorylation of eNOS as well. XAand 4HD-dependent wound healing was also blocked by hemoglobin, a carbon monoxide (CO) absorbent. A CO-releasing molecule facilitated the wound healing, which was suppressed by pretreatment with L-NMMA. These results suggest that XA and 4HD stimulate wound healing by increasing HO-1 expression with subsequent CO production, which activates eNOS followed by NO generation. Our findings indicate that the two chalcones in Angelica keiskeimay have a preventative effect against atherosclerosis.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129963195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been seen mainly in the expansion of the area under tobacco production. However, just as in any other developing country, smallholder farmers in Malawi face substantial risk of farm income fluctuation. Farm income is subject to price more important for poor farmers because risk plays a role in their decision making regarding risk, which is significant because of unstable market conditions. Risk considerations are the adoption of technologies and allocation of resources. Risk also contributes to their low incomes. The aim of this study, therefore, was to support the decision making of smallholder farmers in view of market risk. A quadratic risk programming model was applied to estimate the minimum income variance and develop an expected income-variance (E-V) e cient frontier for smallholder farmers producing tobacco in the central region of Malawi. Data used in this study were from production and marketing records ( ) of farmers belonging to Chiyambi Producers and Marketing Cooperative a farmers’ organization in Dowa district, in the central region of Malawi. The results indicate that production e ciency varied among farmers according to their production technology. Moreover, they suggest that farmers on average should change the land area used for growing maize, tobacco, groundnuts, and phaseolus beans by . , . , . , and . , respectively, to optimize risk. Farmers’ attitudes toward risk and development of expectation methods for generating time-series data that take into account dependencies in the data are important issues that should be considered in the future studies.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132740297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sustainability concept is having a huge impact in the palm oil industry as it faces unprecedented scrutiny from governments, regulators, investors, and consumers in terms of how its business practices, supply chain, and products impact the environment. This paper gives an overview of recent research developments in refining processes and product diversification. Recent technologies for the preparation of oils, fats, and their derivatives using palm oil as a starting material are discussed. Research in the following areas is reviewed: (1) development of low free fatty acid crude palm oil; (2) refining process improvements to reduce 3-monochloropropane-1,2-diol and glycidol levels; (3) development of new palm-based emulsion products; and (4) production of palm-based functional lipids. Continuous improvements in our understanding of the refining process of this major edible oil will play an important role in the sustainable development of the palm oil industry. Safety and health issues related to palm oil products are also closely related to the sustainable development of the palm oil industry.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133304878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
