(2005)The energetic metabolism and its relationship with body weight generated a vivid controversy, since the Rubner's surface law was introduced into biology. Recently, the multifactor theory (Darveau et al) has caused again a ...
-
(2004)The mechanism by which homocysteine (Hcy) causes endothelial dysfunction is probably mediated by oxidative stress. The aim of this study was to evaluate the effect of oxidative stress on endothelial function in young and ...
-
(2004)Twenty-nine arylisopropylamines, substituted at the β-position of their side chain by an oxo, hydroxy, or methoxy group, were evaluated in vitro as MAO-A and MAO-B inhibitors. The oxo derivatives ('cathinones') were in ...
-
(2006)The aim of the present study was to test the hypothesis that induction of cytochrome P450 2E1 (CYP2E1) in the liver of patients with non-alcoholic fatty liver disease (NAFLD) is correlated both with the in vivo activity ...

Laminin promotes in vitro outgrowth of mouse trophoblast from blastocysts cultured in hanging drop (1997)Differentiation of the nonadherent trophectoderm cells of the mammalian embryo into attachment-competent trophoblast cells appears to be a necessary event for invasion of the uterine stroma. We have used a hanging drop ...

-
(Society of Biology of Chile, 2004)In summary, this limited discussion of recent developments concerning a few signaling pathways and associated cellular systems hopefully underscores the importance of multiprotein complex formation in cellular signaling, ...
-
(Society of Biology of Chile, 2004)Proteins rich in sulfhydryl groups, such as metallothionein, are present in several strains of the parasite Trypanosoma cruzi, the etiological agent of Chagas' disease. Metallothionein-like protein concentrations ranged ...
-
(2004)We report that oxidative phosphorylation and Ca2+ uptake processes are enhanced in liver mitochondria isolated from benzo[a]pyrene (B[a]P)-treated rats. The carcinogen did not affect either the respiratory control index ...
