The submergence zone is comprised of two valleys, the Bhagirathi submergence zone and the Bhilangna submergence zone. Four major plant communities were identified in both the submergence zones with varied associations through TWINSPAN. Most of the communities are similar in both the submergence zones, while their associations altered due to the micro-climatic variations. The species richness and diversity was high in most of the sites in the Bhagirathi submergence zone compared to the Bhilangna submergence zone, where species richness and diversity were more or less similar in most of the sites. The evenness values in most of the sites indicate that the species were distributed evenly in the Bhagirathi submergence zone, while heterogeneously in most of the sites in the Bhilangna submergence zone. However, the rate of species change, for example, the sdiversity was higher in the Bhilangna submergence zone compared to the Bhagirathi submergence zone. The biomass of Lantana (74.5%) was high for the entire submergence zone compared to Carissa (25.4%), with respect to the total available biomass for both species. However, the extraction was more for Carissa (2.2%) as compared to Lantana (1.2%), with respect to the total biomass of each species.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2009.3.0.6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70597454","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}

Heat stress inhibited chlorophyll accumulation at 45°C for 8 h and caused marked alterations in the chlorophyll a fluorescence and photosynthesis in the primary leaves of the wheat cultivars at 37°C and 45°C for 8 h. Examination of the 2-D SDS polyacrylamide gel electrophoresis analysis of the thylakoid membrane proteins from the two wheat cultivars showed that while a heat treatment at 37°C and 45°C did not induce or enhance the synthesis of any protein. While the synthesis of some proteins were repressed when compared to the control temperature cultivars, the photosynthetic responses of Karacadag were less altered than Firat to the effect that; Karacadag showed lower reduction in the chlorophyll content, FV and FV/FM parameters where the F0 parameter only increased in the Firat cultivar at 45°C. Therefore, Karacadag was determined to be a heat tolerant cultivar that can be used for cultivation in warmer regions.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70597131","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}

To clarify the mechanisms of the anti-inflammatory activities of Sargassum micracanthum, we evaluated whether extracts of S. micracanthum could modulate the production of NO by activated macrophages. S. micracanthum were extracted with 80% EtOH. The extract was then successively partitioned with hexane, CH 2 Cl 2 , EtOAc, BuOH, and water. The results indicate that the hexane and CH2Cl2 fractions of S. micracanthum extract were effective inhibitors of LPS-induced NO and prostaglandin E2 (PGE2) production in RAW 264.7 cells. The inhibitory effects of the hexane and CH2Cl2 fractions of S. micracanthum were accompanied by dosedependent decreases in the production of iNOS and COX-2 proteins and iNOS and COX-2 mRNA expression. To test the inhibitory effects of S. micracanthum fractions on other cytokines, we also performed ELISA and RT-PCR assays for TNF- , IL-1s, and IL-6 in LPSstimulated RAW 264.7 macrophage cells. In these assays, the hexane and CH2Cl2 fractions of S. micracanthum produced dose-dependent decreases in the production and mRNA expression of TNF- , IL-1s, and IL-6. To test the potential application of S. micracanthum extract as a cosmetic material, we also performed MTT assays on human dermal fibroblast cells, as well as primary skin irritation tests. In these assays, S. micracanthum extracts did not induce any adverse reactions. Based on these results, we suggest that S. micracanthum extracts may be considered potential anti-inflammatory candidates for topical application.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2009.3.0.17","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70596999","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}
