Toxicogenetic effects of low concentrations of the pesticides imidacloprid and sulfentrazone individually and in combination in in vitro tests with HepG2 cells and Salmonella typhimurium
(Elsevier B. V., 2015)
The insecticide imidacloprid and the herbicide sulfentrazone are two different classes of pesticides that are used for pest control in sugarcane agriculture. To evaluate the genotoxic potential of low concentrations of ...
Photodynamic therapy combined to cisplatin potentiates cell death responses of cervical cancer cells
(2017-02-10)
Background: Photodynamic therapy (PDT) has proven to be a promising alternative to current cancer treatments, especially if combined with conventional approaches. The technique is based on the administration of a non-toxic ...
Impacts of in vivo and in vitro exposures to tamoxifen: Comparative effects on human cells and marine organisms
(2019-08-01)
Tamoxifen (TAM) is a first generation-SERM administered for hormone receptor-positive (HER+) breast cancer in both pre- and post-menopausal patients and may undergo metabolic activation in organisms that share similar ...
Tannic acid, a promising anti-photoaging agent: Evidences of its antioxidant and anti-wrinkle potentials, and its ability to prevent photodamage and MMP-1 expression in L929 fibroblasts exposed to UVB
(2020-11-20)
Chronic and unprotect UV exposure leads to skin oxidative stress, following accumulation of damaged cellular components and downstream activation of specific signaling pathways, culminating in premature skin aging (photoaging). ...
Antigen otoxicity of Agaricus blazei mushroom organic and aqueous extracts in chromosomal aberration and cytokinesis block micronucleus assays in CHO-k1 and HTC cells
(Elsevier B.V., 2006-04-01)
Agaricus blazei (Ab) has become popularly known for its medicinal properties. Scientifically, it has been tested with regard to its capacity to protect genetic material against damage. We examined different organic extracts ...
Flavonols protect Arabidopsis plants against UV-B deleterious effects
(Oxford University Press, 2013-01)
Flavonols are synthesized by flavonol synthase (FLS) enzymes (Martens et al., 2010). These compounds absorb UV-B light in the 280?320 nm region, and their concentration increases in plants exposed to environmental abiotic ...
Influência da fragmentação de habitats no fluxo gênico e estrutura cromossômica de espécies de anuros do bioma Mata Atlântica no sul do Brasil
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2022-09-21)
The Atlantic Forest is a vast and heterogeneous forest biome, covering about 17% of
Brazilian territory with only 12% of the original area remaining, resulting from an extremely
fragmented landscape. Fragmentation can ...
The Complex Biogeography of the Plant Pathogen Xylella fastidiosa: Genetic Evidence of Introductions and Subspecific Introgression in Central America
(2014-11)
The bacterium Xylella fastidiosa is a plant pathogen with a history of economically damaging introductions of subspecies to regions where its other subspecies are native. Genetic evidence is presented demonstrating the ...
