Antitumor effects of a natural anthracycline analog (Aloin) involve altered activity of antioxidant enzymes in HeLaS3 cells
(Taylor & Francis Inc, Philadelphia, 2007)
The anti proliferative and cytotoxic potential of the natural anthracycline aloin from Aloe vera was tested on human uterine carcinoma HeLaS3 cells. Aloin showed a pronounced antiproliferative effect at physiological ...
Molecular mechanics study of nickel(II) octaethylporphyrin adsorbed on graphite(0001)
(MDPI, 2007)
The effects of adsorption on the graphite(0001) surface on the nonplanar distortions of nickel(II) octaethylporphyrin were studied by molecular mechanics (MM) approach. Using the Consistent Force Field (CFF) program with ...
Far infrared properties of bulk sintered and thin film Zn2SnO4
(Elsevier, 2007)
Room temperature far infrared reflectivity spectra of single phase spinel zinc-stannate thin films, prepared by rf magnetron sputtering on a glass substrate, and bulk sintered samples were measured. The sintered samples ...
Synthesis of amorphous boron carbide by single and multiple charged boron ions bombardment of fullerene thin films
(Elsevier, 2007)
In this paper, results of structural modification of fullerene thin films by single and multiple charged boron ions (B+, B3+) are presented. The applied ion energies were in the range of 15–45 keV. The characterization of ...
Consequences of MnSOD interactions with nitric oxide: Nitric oxide dismutation and the generation of peroxynitrite and hydrogen peroxide
(USA :Taylor & Francis INC, 2007)
The present study demonstrates that manganese superoxide dismutase (MnSOD) Escherichia coli, binds nitric oxide (NO) and stimulates its decay under both anaerobic and aerobic conditions. The results indicate that previously ...
Antiproliferative activity of β-hydroxy- β-arylalkanoic acids
(MDPI, 2007)
Article describes the synthesis of fifteen β-hydroxy- β-arylalkanoic acids by Reformatsky reaction using the 1-ethoxyethyl-2- bromoalkanoates, aromatic or cycloalkyl ketones or aromatic aldehydes. The short survey of ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier B.V., 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Synthesis of some steroidal oximes, lactams, thiolactams and their antitumor activities
(Elsevier, 2007)
The antiproliferative activity of previously synthesized (Z)-cholest-4-en-6-one oxime (1), (E)-cholest-4-en-6-one oxime (2), 7-aza-B-homocholest-4-en-6-one (3) and 6-aza-B-homocholest-4-en-7-one (4) and newly synthesized ...
Immobilization of glucoamylase via its carbohydrate moiety on macroporous poly(GMA-co-EGDMA)
(Elsevier, 2007)
We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well ...
Different responses of mesenteric artery from normotensive and spontaneously hypertensive rats to nitric oxide and its redox congeners
(Springer, 2007)
The conversion of nitric oxide (NO
) into its congeners nitrosonium (NO ) and nitroxyl (HNO/NO) ions may have important consequences for signal transduction and physiological responses. Manganese-containing superoxide ...
