Altered matrix metalloproteinases and tissue inhibitors of metalloproteinases in embryos from diabetic rats during early organogenesis
(Elsevier Inc, 2011-12)
Maternal diabetes increases the risks for embryo malformations. Matrix metalloproteinase-2 (MMP-2) and MMP-9 are two relevant MMPs for embryo development. Here, we addressed whether changes in these MMPs and in tissue ...
Impacts of agricultural intensification on avian richness at multiple scales in Dry Chaco forests
(Elsevier, 2014-11)
Agricultural expansion and intensification is driving rapid landscape modification in the South American Gran Chaco, affecting biodiversity at multiple spatial scales. Research on biodiversity change in modified landscapes ...

Spironolactone and hydrochlorothiazide exert antioxidant effects and reduce vascular matrix metalloproteinase-2 activity and expression in a model of renovascular hypertension
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Background and purpose: Increased oxidative stress and up-regulation of matrix metalloproteinases (MMPs) may cause structural and functional vascular changes in renovascular hypertension. We examined whether treatment with ...
Cardiac remodeling induced by smoking: Concepts, relevance, and potential mechanisms
(2012-12-04)
Cardiac or ventricular remodeling is characterized by molecular, cellular, and interstitial alterations that lead to changes in heart size, mass, geometry and function in response to a given insult. Currently, tobacco smoke ...
