Vasopressin and angiotensin receptors of the medial septal area of the brain in the control of thirst and salt appetite induced by vasopressin in water-deprived and sodium-depleted rats
(Elsevier B.V., 2007-10-01)
In this study we investigated the influence of d(CH2)(5)-Tyr (Me)-AVP (A(1) AVP) and [Adamanteanacatyl(1),D-ET-D-Tyr(2), Va1(4), aminobutyril(6) ,As-8,As-9]-AVP 9 (A(2)AVP), antagonists of V-1 and V-2 arginine(8)-vasopressin ...
The activity of microcin E492 from Klebsiella pneumoniae is regulated by a microcin antagonist
(Blackwell Publishing Ltd, 1996)
Microcin E492 is a polypeptide antibiotic that is produced and excreted by Klebsiella pneumoniae. Different growth conditions of the producer strain affect microcin activity. The production of a microcin antagonist is ...
Suppression of wheal and flare in histamine test by the main H1 antihistamines commercialized in Brazil
(2018-03-01)
Background: Several dermatoses are mediated by histamine, such as urticaria, angioedema, and papular urticaria. There are no Brazilian studies comparing the potency of antihistamines. Objectives: To evaluate the tolerability ...
Effects of subtypes alpha- and beta-adrenoceptors of the lateral hypothalamus on the water and sodium intake induced by angiotensin II injected into the subfornical organ
(Elsevier B.V., 2000-10-27)
The present experiments were conducted to investigate the role of the alpha (1A)-, alpha (1B), beta (1),- and beta (2)-adrenoceptors of the lateral hypothalamus (LH) on the water and salt intake responses elicited by ...

Effects of subtypes of adrenergic and angiotensinergic antagonists on the water and sodium intake induced by adrenaline injected into the paraventricular nucleus
(Elsevier B.V., 2003-12-24)
The present experiments were conducted to investigate die role of the alpha(1A)-, alpha(1B)-, beta(1)-, beta(2)-adrenoceptors, and the effects of losartan and CGP42112A (selective ligands of the AT(1) and AT(2) angiotensin ...
GnRH agonist versus GnRH antagonist in IVF/ICSI cycles with recombinant LH supplementation: DNA fragmentation and apoptosis in granulosa cells
(Elsevier B.V., 2012-11-01)
Objective: To compare the level of apoptosis and DNA fragmentation in the human granulosa cell (GC) layer exposed to an agonist or antagonist of GnRH in intracytoplasmic sperm injection (ICSI) cycles supplemented with ...
Endothelin A receptor antagonist modulates lymphocyte and eosinophil infiltration, hyperreactivity and mucus in murine asthma
(ELSEVIER SCIENCE BV, 2008)
Levels of endothelins are particularly high in the lung, and there is evidence that these peptides are involved in asthma. Asthma is a chronic inflammatory disease associated with lymphocyte infiltration. In the present ...
