Análisis de la acidez de la precipitación en la Península Ibérica
Marín, E.; Lavín, N.; Hernández, E.; Rúa, A.ACIDITY OF PRECIPITATION IN THE IBERIAN PENINSULA – Acidity of precipitation in the Iberian Peninsula between 1986 and 1997 is studied in this paper. The main objectives are the analysis of its variability, seasonal cycle, and trend. The results show a higher acidity of precipitation in Portugal than in Spain, although precipitation is acid in both countries. In general, the pH variability is lower in Portugal ...
Roles of mitogen-activated protein kinases and angiotensin II in renal development
Balbi,A.P.C.; Francescato,H.D.C.; Marin,E.C.S.; Costa,R.S.; Coimbra,T.M.Experimental and clinical evidence suggests that angiotensin II (AII) participates in renal development. Renal AII content is several-fold higher in newborn rats and mice than in adult animals. AII receptors are also expressed in higher amounts in the kidneys of newborn rats. The kidneys of fetuses whose mother received a type 1 AII receptor (AT1) antagonist during gestation present several morphological altera...
