Oxidative Stress in Hypertension: Mechanisms and Therapeutic Opportunities
(Johann Ambrosius Barth Verlag Medizinverlage Heidelberg GMBH, 2015)
Hypertension is a highly prevalent disease worldwide. It is known for being one of the most important risk factors for developing cardiovascular disease, including acute myocardial infarction and stroke. Therefore, during ...
Constituents and biological activities from Muehlenbeckia hastulata
(VERLAG Z NATURFORSCH, 2002-09)
Muehlenbeckia hastulata (J. E.Sm.) Johnst. used mainly for its abortive properties was found active for oxytoxic and analgesic activities in a biological activity screening (oxytoxic, analgesic, antimicrobial, cytotoxic ...
Cu(II)–disulfide complexes display simultaneous superoxide dismutase- and catalase-like activities
(Elsevier, 2013)
Superoxide is a potentially toxic by-product of cellular metabolism.We have addressed here the in vitro ability
of complexes formed between copper(II) ions and various biologically-occurring disulfides (RSSR: oxidized ...
Neutrophils suppress γδ T-cell function
(Wiley VCH Verlag, 2013-12)
γδ T cells have been shown to stimulate the recruitment and activation of neutrophils through the release of a range of cytokines and chemokines. Here, we investigated the reverse relationship, showing that human neutrophils ...
Inhibition of lymphocyte-induced angiogenesis by free radical scavengers
(Elsevier, 1994-09)
Solid tumors induce an angiogenic response by the host blood vessels to form a new vascular network for the supply of fresh nutrients and oxygen responsible for tumor growth. Furthermore, tumor growth and metastatic spread ...
Avaliação da sinalização purinérgica em tecido hepático e esplênico de camundongos infectados com Toxoplasma gondii e tratados com disseleneto de difenila
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2017-02-03)
Toxoplasmosis is a zoonosis of worldwide distribution caused by the parasite Toxoplasma gondii, which in general develops asymptomatic and chronic characteristic infection in mammals and birds. In this period, the parasite ...
The use of jarilla native plants in a Diaguita-Calchaquí indigenous community from northwestern Argentina: An ethnobotanical, phytochemical and biological approach
(Elsevier Ireland, 2020-01)
Ethnopharmacological relevance: In northwestern Argentina inhabit several ancient indigenous communities with diverse cultural and historical background. Geographical isolation has contributed to the prevalence of a native ...
Role of superoxide anions in the redox changes affecting the physiologically occurring Cu(I)-glutathione complex
(2011)
The physiologically occurring copper-glutathione complex, [Cu(I)-[GSH]2], has the ability to react continually with oxygen, generating superoxide anions (O 2 -). We addressed here the effects that superoxide removal has ...
