Solar UV radiation modulates daily production and DNA damage of marine bacterioplankton from a productive upwelling zone (36°S), Chile
(Elsevier Science, 2007-04)
In upwelling ecosystems, such as the Humboldt Current system (HCS) off Concepción, the effects of solar radiation on bacterioplankton incorporation rates have been related to previous light acclimation and responses to ...
Combined effects of ultraviolet radiation and temperature on morphology, photosynthesis, and DNA of Arthrospira (Spirulina) Platensis (Cyanophyta)
(Wiley Blackwell Publishing, Inc, 2008-06)
Natural levels of solar UVR were shown to break and alter the spiral structure of Arthrospira (Spirulina) platensis (Nordst.) Gomont during winter. However, this phenomenon was not observed during summer at temperatures ...
DNA and neutrophil extracellular traps release, novel potential biomarkers and therapeutic targets of joint Damage In Hemophilia
(Wiley, 2019)
Background and aims: Hemarthroses cause major morbidity in hemophilia resulting in chronic hemophilic synovitis (CHS), osteochondral degeneration and arthropathy. Although the initial events causing joint damage remain ...
Oxidative stress and RNA/DNA ratio following longline capture in the silky shark Carcharhinus falciformis (Müller & Henle, 1839)
(Pontificia Universidad Católica de Valparaíso, 2017)
Glassy carbon electrodes modified with CNT dispersed in chitosan: Analytical applications for sensing DNA-methylene blue interaction
(Elsevier Science Sa, 2009-09)
In this work we report the optimization of a chitosan (CHI) and carbon nanotubes (CNT) modified electrode, CNT-CHI, to study the dsDNA interaction with methylene blue (MB), a well-known DNA intercalator. The analytical ...
In vitro studies of DNA damage and repair mechanisms induced by BNCT in a poorly differentiated thyroid carcinoma cell line
(Springer, 2018-05)
Boron neutron capture therapy (BNCT) for aggressive tumors is based on nuclear reaction [10B (n, α) 7Li]. Previously, we demonstrated that BNCT could be applied for the treatment of undifferentiated thyroid carcinoma. The ...
Stress hormones reduce the efficacy of paclitaxel in triple negative breast cancer through induction of DNA damage
(Nature Publishing Group, 2015-04)
Background: The mechanisms by which stress hormones impact triple-negative breast cancer (TNBC) etiology and treatment are unclear. We have previously shown that stress hormones, cortisol, and catecholamines induce rapid ...
Analysis of apoptosis and DNA damage in bovine cumulus cells after exposure in vitro to different zinc concentrations
(Academic Press Ltd - Elsevier Science Ltd, 2011-05)
The purpose of this study was to investigate the effect of Zn (zinc) concentration on CCs (cumulus cells) during in vitro maturation. For this purpose, DNA integrity of CCs by addition of different Zn concentrations [0 ...
Oxidative stress-induced premature senescence dysregulates VEGF and CFH expression in retinal pigment epithelial cells: Implications for Age-related Macular Degeneration
(ELSEVIER BV, 2016-04)
AbstractOxidative stress has a critical role in the pathogenesis of Age-related Macular Degeneration (AMD), a multifactorial disease that includes age, gene variants of complement regulatory proteins and smoking as the ...
UVR-induced photosynthetic inhibition dominates over DNA damage in marine dinoflagellates exposed to fluctuating solar radiation regimes
(Elsevier Science, 2008-10)
The combined effect of solar radiation (UV-B (280-315 nm), UV-A (315-400 nm) and PAR (400-700 nm)) and vertical mixing (i.e., fluctuating radiation regimes) on the marine dinoflagellates Gymnodinium chlorophorum, Heterocapsa ...
