In the previous study, the gamma irradiation on mahkota dewa bark with the optimum dose of 7.5 kGy could be used for decontamination of bacteria and fungus/yeast. In this report, the effect of gamma irradiation with the dose of 7.5 kGy on the bioactivities of mahkota dewa (Phaleria macrocarpa (Scheff) Boerl.) bark against leukemia L1210 cells was studied. The control and irradiated samples were successively macerated with n-hexane and ethyl acetate. In the previous results, silica gel column chromatography of ethyl acetate extract of non irradiated sample (control) gave 8 fractions. Among these fractions, fraction 6 indicated the most cytotoxic-potential fraction, so that in this experiment, the ethyl acetate extract of irradiated and non irradiated sample were fractionated with the same manner as previous fractionation. The fraction 6 obtained both from control and irradiated samples were then assayed their inhibitory activities against 4 kinds of human cancer lines, i.e. HeLa, THP-1, HUT-78 and A-549. The results showed that the fraction 6 from control sample gave IC50 values of 3.65, 5.59, 3.55, and 4.06 µg/mL, against HeLa, THP-1, HUT-78 and A-549, respectively, meanwhile fraction 6 from irradiated sample gave IC50 values of 8.26, 7.02, 5.03, and 5.59 µg/mL, respectively. Gamma irradiation dose of 7.5 kGy on mahkota dewa bark could decreased the cytotoxic activity of fraction 6 as the most cytotoxic-potential fraction against HeLa, THP-1, HUT-78 and A-549 cancer cell lines, but decreasing the cytotoxic activity has not exceeded the limit of an extract and the fraction declared inactive.

Chemical stability was determined in solution media of acid, neutral, and base. Adsorption selectivity was obtained with determination of selectivity coefficient (α) of Cd2+ ion toward its ionic pair such as Ag+, Zn2+, Cu2+, and Ni2+ ions. Nannochloropsis sp Cd(II)-IIP material is very stable in acid media and lack stable in base media as well as it can be reused for extraction 4 cycles with adsorption capacity value > 95% using eluent of 0.1 M Na2EDTA. Selectivity of Cd(II)-IIP material upon Cd2+ ion is higher than non imprinted polymer (NIP) and it increases with these orders; Cd2+/Ag+ < Cd2+/Zn2+ < Cd2+/Cu2+ < Cd2+/Ni2+ for each α at metal ionic ratio of 1:1; 0.887; 20.180; 28.053; 33.417, respectively.", "publicationTitle": "Indonesian Journal of Chemistry", "publisher": "", "place": "", "date": "14/02/2012", "volume": "12", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "94-99", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "", "citationKey": "", "url": "http://pdm-mipa.ugm.ac.id/ojs/index.php/ijc/article/viewArticle/669", "accessDate": "2012-04-25T17:00:02Z", "PMID": "", "PMCID": "", "ISSN": "1411-9420", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "pdm-mipa.ugm.ac.id", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Nannochloropsis sp", "type": 1 }, { "tag": "adsorption selectivity", "type": 1 }, { "tag": "ionic imprinted", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2012-04-25T17:36:26Z", "dateModified": "2012-04-25T17:36:26Z" } }, { "key": "T7ZUSPRX", "version": 1, "library": { "type": "group", "id": 18673, "name": "pustaka", "links": { "alternate": { "href": "https://www.zotero.org/groups/pustaka", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/18673/items/T7ZUSPRX", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/pustaka/items/T7ZUSPRX", "type": "text/html" } }, "meta": { "createdByUser": { "id": 215522, "username": "muhamad", "name": "Muhamad Abdulkadir Martoprawiro", "links": { "alternate": { "href": "https://www.zotero.org/muhamad", "type": "text/html" } } }, "creatorSummary": "Widjajakusuma et al.", "parsedDate": "2012-02-14", "numChildren": 1 }, "data": { "key": "T7ZUSPRX", "version": 1, "itemType": "journalArticle", "title": "EFFECT OF THE ION TREATMENT ON AN RNA HAIRPIN: MOLECULAR DYNAMICS STUDY", "creators": [ { "creatorType": "author", "firstName": "Elisabeth Catherina", "lastName": "Widjajakusuma" }, { "creatorType": "author", "firstName": "Alessandra", "lastName": "Villa" }, { "creatorType": "author", "firstName": "Gerhard", "lastName": "Stock" } ], "abstractNote": "Molecular dynamics has been employed to study the effect of ion treatment on the stability of 14-nucleotide RNA hairpin of Coxsackievirus B3. Three AMBER force fields were used: AMBER94, AMBER98, and AMBER99, which showed no significant structural difference of the hairpin. Thereafter, we applied two different long-range electrostatic treatments that were reaction field and PME methods, and calculated the distribution of ions around the hairpin. Although the structural stabilities of the MD simulations using both methods were similar in 0.14 M Na+, ion environment around the hairpin was notably different. In particular, structural stabilition of the hairpin with increasing ion concentration and with ion Mg2+ cannot be accommodated by simulations using reaction field method. Furthermore, the MD simulations using PME method suggested the strong similarity in structural and dynamical properties of the hairpin with 0.14 M Na+, 0.50 M Na+, 1,03 M Na+, and 0.08 M Mg2+ concentrations.
