Nitric oxide signaling in the retina: What have we learned in two decades?
(2012)
Two decades after its first detection in the retina, nitric oxide (NO) continues to puzzle visual neuroscientists. While its liberation by photoreceptors remains controversial, recent evidence supports three subtypes of ...
Angiotensin II causes a dual effect on potassium permeability in adrenal glomerulosa cells
(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 ...
Plant Physiological Responses to Nutrient Solution: An Overview
(2018-03-20)
Being sessile, plants developed adaptive and flexible strategies for nutrient acquisition. Localized deficiency or oversupply of many nutrients induces morphological and physiological adaptations, such as gas exchange, ...
Effects of the fungicides azoxystrobin, pyraclostrobin and boscalid on the physiology of Japanese cucumber
(2018-01-26)
Strobilurins are fungicides with beneficial physiological effects on crop yield due to promotion of net carbon assimilation, nitrate reductase enzyme activity, stress tolerance and hormonal balance. The carboxamides ...
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, ...

Catechol-mediated effects of harmaline on the action potential of rat atrial fibres
(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 ...
Catechol mediated effects of harmaline on the action potential of rat atrial fibres
(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 ...
Mechanical effects of heart contraction on coronary flow
(1975)
The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing them independently ...
