C60(glucosamine)6, a water-soluble fullerene with strong free radical scavenging activity, was applied to evaluate its effect on renal ischemia/reperfusion-induced apoptosis formation and superoxide generation. C60(glucosamine)6 pretreatment, but not posttreatment, significantly reduced renal ischemia/reperfusion-induced apoptosis and superoxide generation and, consequently, ameliorated renal hemodynamic effects. Up-regulation in bcl-2 and bcl-xL of the rat kidney was evident in C60(glucosamine)6 pretreated, posttreated, and nontreated groups. However, exaggerated forced expression of bcl-2 and bcl-xL was found in the C60(glucosamine)6 pretreated group. Our results conclude that forced expression of bcl-2 and bcl-xL by the novel water-soluble fullerene, C60(glucosamine)6, can reduce renal ischemia/ reperfusion-induced oxidative stress.","PeriodicalId":12470,"journal":{"name":"Fullerene Science and Technology","volume":"123 1","pages":"77 - 88"},"PeriodicalIF":0.0,"publicationDate":"2001-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86576334","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}

Toluene extraction of the soot results in a solution of C60, C70, and higherc fullerenes. Without separation, absolute determination of the contents is not possible, leaving the researcher to comment only on the C60/C70 ratio of the solution. High-performance liquid chromatography, nuclear magnetic resonance, and scanning tunneling microscopy imaging techniques were reported in the literature for determining the C60/C70 ratio of the mixtures. These methods require tedious experiments and produce slightly differing results as well. In this communication, a new and relatively quick method is proposed for the simultaneous determination of the yields of C60 and C70 (not the ratio) in fullerene-containing solutions by ultraviolet-visible spectrophotometric analysis.","PeriodicalId":12470,"journal":{"name":"Fullerene Science and Technology","volume":"48 1","pages":"103 - 111"},"PeriodicalIF":0.0,"publicationDate":"2001-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86013422","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}

Dynamic light scattering experiments showed aggregates with an average size of ∼100 nm. The solute has a broad weak fluorescence emission (ϕf = 1.8 × 10−3) in the 450–650 nm region, which remained independent of solute concentration. The broad transient absorption band in the 450–900 nm region (ϵ660 = 2170 dm3 mol−1 cm−1), which formed immediately on laser flash photolysis (λex = 355 nm, 35 ps), is assigned to singlet-singlet transition. It decays to a triplet excited state whose absorption is observed to depend strongly on solute concentration. In dilute solutions, an absorption band with λmax = 590 nm is seen, and at high solute concentration a broad absorption in the 500–900 nm region is observed. The eaq − reacts with the solute with a bimolecular rate constant of 1.7 × 108 dm3 mol−1 s−1 and forms weak broad absorption bands at 440, 540, 620, 870, 940, and 1020 nm. Isopropanol radicals also react with the solute with a bimolecular rate constant of 2.3 × 108 dm3 mol−1 s−1 with the formation of a transient optical absorption spectrum similar to that observed on reaction with eaq − and assigned to a solute radical anion. The •H and −OH radicals react with bimolecular rate constants of 3.2 × 109 and 4.4 × 109 dm3 mol−1 s−1, respectively, and form transient absorption bands at 440, 510, and 660 nm.

These conditions are maintain fixed while the irradiation dosages were changed to 50, 100, 200, and 500 Mrad. The optimization of the dosage used for the production of MoTe2 nanotubes was obtained from the analysis of the samples that were examined in a high-resolution transmission electron microscope. The most efficient production of MoTe2 nanotubes was obtained at the range between 100 and 200 Mrad.
