(1988)In previous studies it was shown that angiotensin II causes a Ca-dependent increase in the K permeability of bovine adrenal glomerulosa cells [Am. J. Physiol. 250 (Endocrinol. Metab. 13): E125-E130, 1986]. Here we show ...
-
(1989)Acute hypoxemia results in hypertension, bradycardia, and cardiac output redistribution in fetal sheep. The blood flow redistribution is produced by differential changes in vascular resistance of various fetal organs. ...
-
(1977)The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the slow ...

(Oxford University Press, 1977)Summary: The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the ...

(1983)We studied the effects of ethanol on total coronary resistance and on the resistance across the left ventricular wall in the isolated empty beating heart of the dog. The coronaries were perfused with homologous fresh blood, ...

(1976)We reported the final results obtained in a group of 30 patients with gastric cancer confined to the mucosa or submucosa (early gastric cancer) and in 29 cases with cancer infiltration up to the muscularis propria (intermediate ...
-
(University of Chicago Press, 1998)The adaptive modulation hypothesis posits that the expression of digestive proteins should be modulated in response to intake of their respective substrates. A corollary of this hypothesis suggests that dietary flexibility ...

Effect of angiotensin II, ATP, and ionophore A23187 on potassium efflux in adrenal glomerulosa cells (1986)Angiotensin II stimulus on perifused bovine adrenal glomerulosa cells elicited an increase in 86Rb efflux from cells previously equilibrated with the radioisotope. When 45Ca fluxes were measured under similar conditions, ...
-
(Springer-Verlag, 1963)Hematocrit levels were measured on a series of Chilean mammals including PHYLLOTIS DARWINI RUPESTRIS, AKODON ANDINUS, AKODON BERLEPSCHII, LAGIDIUM VISCACIA and CHINCHILLA BOLIVIANA from high altitude; and PHYLLOTIS D. ...
-
(1989)Intravenous administration of the opioid receptor antagonist naloxone to asphyxiated fetal sheep increases the arterial blood pressure. We examined the hypothesis that endogenous opioids modify the cardiac output distribution ...
-
(1989)Four hundred strains of enterobacteria, isolated before the introduction of trimethoprim as a single agent in Chile, were studied. One hundred and thirty six strains (34%) were resistant to ≥8 mg/l of trimethoprim and 118 ...
