(1988)Rat spermatogenic cells have glycolytic rates of 124 ± 36 nmol lactate · mg protein -1 · h-1. Maximum glycolytic rates in the absence of oxidative phosphorylation do not exceed the basal rates by>40%. From the rates of ...
-
(Kluwer Academic Publishers-Plenum Publishers, 1983)Our aim was to develop a chronic canine model that would serve for the simultaneous measurements of postprandial gastric secretion and emptying by a double-marker dilution technique without artificially interfering with ...
-
(2010)Bidirectional signaling between the sarcolemmal L-type Ca2+ channel (1,4-dihydropyridine receptor [DHPR]) and the sarcoplasmic reticulum (SR) Ca2+ release channel (type 1 ryanodine receptor [RYR1]) of skeletal muscle is ...
-
(2010)Bidirectional communication between the 1,4-dihydropyridine receptor (DHPR) in the plasma membrane and the type 1 ryanodine receptor (RYR1) in the sarcoplasmic reticulum (SR) is responsible for both skeletal-type ...
-
(2007)A great body of experimental evidence collected over many years indicates that calcium has a central role in a variety of neuronal functions. In particular, calcium participates in synaptic plasticity, a neuronal process ...
-
(1981)Keyhole limpet hemocyanin forms ion-conducting channels in planar lipid bilayer membranes. Ionic current through the open hemocyanin channel presents the following characteristics: (a) it is carried mainly by cations; (b) ...
-
(Maney Publishing, 1997)The influence of acetaminophen (APAP) treatment (400 mg/kg) on Kupffer cell function was studied in the isolated perfused liver by colloidal carbon infusion, concomitantly with parameters related to oxidative stress ...
-
(1988)Several divalent cations were studied as agonists of a Ca2+-activated K+ channel obtained from rat muscle membranes and incorporated into planar lipid bilayers. The effect of these agonists on single-channel currents was ...
-
(Wiley-Liss Inc., 2014)Copper is an essential cofactor of complex IV of the electron transfer chain, and it is directly involved in the generation of mitochondrial membrane potential. Its deficiency induces the formation of ROS, large mitochondria ...
-
(2011)Soluble amyloid β-peptide oligomers (AβOs), increasingly recognized as causative agents of Alzheimer's disease (AD), disrupt neuronal Ca2+ homeostasis and synaptic function. Here, we report that AβOs at sublethal concentrations ...
-
(2010)Amyotrophic lateral sclerosis (ALS) is the most common adult-onset motoneuron degenerative disease characterized by the selective loss of motoneurons in the spinal ventral horn, most brainstem nuclei, and the cerebral ...
-
(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 ...
-
(Wiley-Liss Inc., 2017)© 2016 Wiley Periodicals, Inc. Diabetic kidney disease (DKD) is the major cause of end stage renal disease. Sodium tungstate (NaW) exerts anti-diabetic and immunomodulatory activities in diabetic animal models. Here, we ...
-
(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. ...
-
(1989)Squid optic nerve sodium channels were characterized in planar bilayers in the presence of batrachotoxin (BTX). The channel exhibits a conductance of 20 pS in symmetrical 200 mM NaCI and behaves as a sodium electrode. The ...
-
(Blackwell Publishing Ltd, 1996)1. Fifty-five C-polymodal nociceptors innervating hairy skin in human volunteers were tested for discrete stimulus-response properties through microneurography. 2. All fifty-five units were responsive to mechanical and ...
-
(2009)Calcium/calmodulin-dependent protein kinase IV (CaMKIV) plays a key role in the regulation of calcium-dependent gene expression. The expression of CaMKIV and the activation of CREB regulated genes are involved in memory ...
-
(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 ...
