The main aim of this study was to determine the anti-inflammatory effect of D. atrovirens bark through the inhibition of nitric oxide (NO) production in lipopolysaccharide-stimulated RAW 264.7 cells.For this purpose, preliminary phytochemical composition and in vitro antioxidant activities of various solvent extracts of D. atrovirens bark were evaluated to select the most effective extract.The methanol extract of D.atrovirens registered the highest amount of total phenolics (476.2 mg GAE/g) and flavonoid (129.0 mg RE/g)contents witha strong antioxidant activity as measured in DPPH (IC50 of 19.52 μg/mL) and ABTS (IC50of 10.82 μg/mL) scavenging activities.Hence, the methanol extract was selected for cell line study. Further, the methanol extract of D. atrovirens effectively inhibited the production of NO in RAW 264.7 cells induced by LPS (13.1 μM at the concentration of 80 μg/mL). It could be concluded that the presence of higher level of total phenolic components in the methanol extract of D. atrovirens bark might be responsible for reducing the NO level in cells.","PeriodicalId":178674,"journal":{"name":"Kongunadu Research Journal","volume":"4 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131752458","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}

Sumathi, Midhun Leo James","doi":"10.26524/krj277","DOIUrl":"https://doi.org/10.26524/krj277","url":null,"abstract":"Indian English Literature pertains to the body of work by writers from India, who pen strictly in the English language and whose native or co-native language could be one of the numerous regional and indigenous language of India. English literature in India is also intimately linked with the works of associates of the Indian Diaspora. Among other writers, Kiran Desai is one of the most renowned writers in the Indian English Literature. With Kiran Desai, a literary tradition is reborn. One of the major themes in the novel is multiculturalism. Multiculturalism relates to communities containing multiple cultures. The term is used in two broad ways, either descriptively or normatively. As a descriptive term it usually refers to the simple fact of cultural diversity. It is generally applied to the demographic make-up of a specific place, sometimes at the organizational level, eg: school, businesses, cities, or nations. As a normative term, it refers to ideologies or policies that promote this diversity or its institutionalization. In this sense, multiculturalism is a society at ease with the rich tapestry of human life and the desire amongst people to express their own identity in the manner they see as fit. Such ideologies or policies vary widely, including country to country. Another major theme in the novel is globalization, which is a process of international integration arising from the interchange of world views, products, and other aspects of culture. Advances in transportation and telecommunications infrastructure, including the rise of the telegraph and its posterity the Internet, are majorfactors in globalization, generating further interdependence of economic and cultural activities. The term globalization has been increasing use since the mid-1980s and especially since the mid-1990s. The term globalization is derived from the word globalize, which refers to the emergence of an international network ofsocial and economic systems. This paper attempts to analyze Kiran Desai’s novel The Inheritance of Loss to bring out the various aspects of multicultural clashes and globalization.","PeriodicalId":178674,"journal":{"name":"Kongunadu Research Journal","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133983489","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}

Out of the plants listed, the dominant families are Asteraceae, Lamiaceae, Fabaceae and Orchidaceae.From the list of the endemic plants in the study, it is indicated that the phylo-genetically advanced families such as Orchidaceae, Asteraceae, and Lamiaceae are the most diversified families on the basis of their number of genera and species. The herbs and shrubs are better represented than the trees in the list. A large number of endemic taxa (about 20 species) are known only by their type collection, which could not be recollected or relocated even after repeated field explorations. It seems that either these taxa are vanished from their localities or alternatively, that species misidentification has occurred.","PeriodicalId":178674,"journal":{"name":"Kongunadu Research Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132508500","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}

XRD spectra indicated the amorphous nature of the films.Surface morphology of the coated films was studied by scanning electron microscope (SEM).
