(PERGAMON-ELSEVIER SCIENCE LTD, 2003-05-09)The tropical spastic paraparesis or human T-cell lymphotropic virus associated myelopathy (TSP/HAM), has been related with an overexpression of matrix metalloproteinases (MMPs), especially MMP-9. Initial studies of reverse ...
-
(ELSEVIER SCIENCE BV, 2002-11-15)Sixty-three pregnant llamas of known breeding date were used in this study. Forty-six of them were submitted to surgery between 186 and 320 days of gestation (52-91% of average gestation period, respectively). Under general ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1999-03-26)There is some evidence that cardiac rather than circulating insulin-like growth factor-1 (IGF-1) levels contribute to the development of renovascular hypertensive left ventricular hypertrophy (LVH), remaining unknown the ...
-
(Sociedad Española de Cardiología, 2001)En este modelo experimental de HVI hipertensiva mixta existe una activación temprana de la ECA plasmática y cardíaca. La administración precoz de un IECA previene el desarrollo de hipertensión e HVI al inhibir el aumento ...

(AMER SOC MICROBIOLOGY, 2001-05)We expressed cDNAs coding for manganese peroxidases (MnPs! from the basidiomycetes Ceriporiopsis subvermispora (MnP1) and Phanerochaete chrysosporium (H4) under control of the alpha -amylase promoter from. Aspergillus ...
-
(CURRENT SCIENCE ASSN, 2001-10-25)Lignin, the most abundant renewable source of aromatic carbon on earth, consists in a highly irregular three-dimensional biopolymer of oxygenated phenylpropanoid units. In natural environments, lignin is only degraded ...
-
(ENDOCRINE SOC, 2000-03)A form of polycystic ovary (PCO) resembling some aspects of the human PCO syndrome can be induced in rats by a single injection of estradiol valerate (EV). An increase in sympathetic outflow to the ovary precedes, by several ...
-
(AMER CHEMICAL SOC, 1996-04)A new series of liquid-crystalline Schiff base lanthanide compounds of the general formula (L''H)(2)L''MX(2) was prepared (L''H = H2n+1CnOC6H3(OH)CHNCmH2m+1; n = 7, 12; m = 14, 18; M = La, Tb, Dy, Er, Nd, Ho, Eu, Pr, and ...
-
(LIPPINCOTT WILLIAMS & WILKINS, 2000-03)Incubation of bovine adrenal chromaffin cells in high K+ (38 mM) during 24-48 h enhanced 2.5 to five times the expression of SNAP-25 protein and mRNA, respectively. This increase was reduced 86% by furnidipine 9(an L-type ...
-
(AMER CHEMICAL SOC, 2003-04-18)Detection Of O-2((1)Delta(g),) phosphorescence emission, lambda(max) = 1270 nm, following laser excitation and steady-state methods was employed to determine the total rate constant, k(T), and the chemical reaction rate ...
-
(ELSEVIER SCIENCE BV, 2003-11-24)The effect of the incorporation of the non-ionic surfactant sucrose palmitate in dioctadecyldimethylammonium chloride(DODAC) large unilamellar vesicles was studies by using several spectroscopic techniques. Significant ...
-
(AMER CHEMICAL SOC, 2004-07-23)The efficient synthesis of tetrapeptide 5 containing, in alternation, cyclobutane and beta-alanine residues is described. NMR experiments both at low temperature in CDCl3 and at 298 K in DMSOd(6) solutions show the ...
-
(KARGER, 2003-04)We studied the effect of thyrotropin-releasing hormone (TRH) applied centrally on the sympathetic activity of the ovary in female rats. Intracerebroventricular (i.c.v.) administration of a dose of 25 ng/kg weight produced ...
-
(Sociedad Chilena de Química, 1998)From Trevoa trinervis Miers (Rhammnaceae), a plant used in Chilean folklore medicine, a triterpenoid called colubrinic acid, has been isolated from a pharmacological active extract. Its structure has been established by ...
