Sensitized formation of oxidatively generated damage to cellular DNA by UVA radiation
(ROYAL SOC CHEMISTRY, 2009)
The survey is aimed at critically reviewing information on the UVA-mediated oxidative reactions to cellular components with emphasis on DNA as the result of mostly photosensitized pathways. It appears clearly that UVA ...
Iron at the center of ferritin, metal/oxygen homeostasis and novel dietary strategies
(Sociedad de Biología de Chile, 2006)
Effect of the metal ion on the anti T. cruzi activity and mechanism of action of 5-nitrofuryl-containing thiosemicarbazone metal complexes
(Wiley-VCH Verlag, 2014)
Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major health problem worldwide. In this work, we report the development of palladium and platinum metal complexes with 5-nitrofuryl-containing ...
Chemiexcitation and Its Implications for Disease
(Elsevier Sci Ltd, 2018)
Quantum mechanics rarely extends to molecular medicine. Recently, the pigment melanin was found to be susceptible to chemiexcitation, in which an electron is chemically excited to a high-energy molecular orbital. In ...
Antimicrobial and antitumor activity of S-methyl dithiocarbazate Schiff base zinc(II) complexes
(2021-03-01)
Schiff bases (SB) obtained from S-methyl dithiocarbazate and aromatic aldehydes: salicylaldehyde (H2L1), o-vanillin (H2L2), pyridoxal (H2L3) and 2,6-diformyl-4-methylphenol (H3L4), and their corresponding Zn(II)-complexes ...
Synthesis, Structure, and Phosphatase-Like Activity of a New Trinuclear Gd Complex with the Unsymmetrical Ligand H(3)L As a Model for Nucleases
(AMER CHEMICAL SOC, 2010)
The new trinuclear gadolinium complex [Gd(3)L(2)(NO(3))(2)(H(2)O)(4)]NO(3)center dot 8H(2)O (1) with the unsymmetrical ligand 2-[N-bis-(2-pyridylmethyl)aminomethyl]-4-methyl-6-[N-bis(2-hydroxy-2-oxoethyl)aminomethyl] phenol ...
Heterologous expression of a novel psychrophilic cu/zn superoxide dismutase from deschampsia antarctica
(ELSEVIER SCI LTD, 2009)
Superoxide dismutase (SOD) catalyzes the conversion of the superoxide radical ((center dot)O(2)(-)) into oxygen and hydrogen peroxide. Deschampsia antarctica is a plant that grows in Antarctica and survives to extreme low ...
Genotoxic effect of chronic exposure to DDT on lymphocytes, oral mucosa and breast cells of female rats
(2011)
The genotoxicity of some environmental contaminants may affect human health directly by damaging genetic material and thus plays an important role in cancer development. Xenoestrogens are one kind of environmental pollutants ...

Genotoxic effect of chronic exposure to DDT on lymphocytes, oral mucosa and breast cells of female rats
(2008)
The objective of this study was to assess and quantify the degree to which interaction between occupational driving and lifting tasks is a risk factor in lumbar spondyloarthrosis etiology. A case-control study was performed ...
