A Cytochemical Evaluation of Blood-brain Barrier Sodium, Potassium- and Calcium-Adenosine Triphosphatase Polarity
… the BBB. Sodium-potassium and calcium-activated adenosine triphosphatase (Na<sup>+</sup>, K<sup>+</sup>-ATPase and Ca<sup>2+</sup>-ATPase) serve as one of the main mechanisms controlling brain Na<sup>+</sup>, K<sup>+</sup>, and Ca<sup>2+</sup> concentrations. The present accepted concept is that …

The Effects of total and partial inhibition of the sodium and pottassium-activated Adenosine Triphosphatase on the isolated perfused rabbit heart
… potassium (K),so'dium (Na), calcium (Ca) , adenosine 5'- triphosphate (ATP),and creatine phosphate (CP) were studied in the isolated Langendorff-perfused rabbit heart.Changes in these parameters- were investigated in relation to the development of ventricular fibrillation (VF) and …

Factors influencing skeletal muscle Na+, K+-ATPase and Plasma [K+] during exercise in humans
The sodium-potassium adenosine triphosphatase enzyme (Na+,K+ -ATPase) regulates muscle cell [Na+],[K+] and muscle membrane potential, therefore playing a fundamental role in muscle excitability. This dissertation primarily examined the effects of acute exercise, training status and chronic …

Studies on the characterization of a soluble factor of a sodium-activated, magnesium-dependent adenosinetriphosphatase in rat cerebral cortex
… in this study, namely, the sodium-activated adenosine triphosphatase, might be involved in maintaining this ionic gradient.<\p>

Preparation of brush border and basolateral membrane vesicles from bovine intestine for nutrient uptake studies
… fractions to the homogenate. Sodium-potassium adenosine triphosphatase and alkaline phosphatase served as the enzyme markers for the basolateral and brush border membranes, respectively. Basolateral membrane vesicles enriched 11.1 fold were isolated from the interface of the 31 and 34% sucrose …

Lysine and methionine transport by bovine jejunal and ileal brush border membrane vesicles
… Alkaline phosphatase and sodium-potassium adenosine triphosphatase served as the marker enzymes for the brush border and basolateral membranes, respectively. The brush border fraction was enriched 5.1-fold over the cellular homogenate. Purification of 10.1-fold over cellular homogenate was …

Glycogen extraction from skeletal muscle sarcoplasmic reticulum: structural and functional implications
… of the sarco(endo)plasmic reticulum Ca2+ adenosine triphosphatase (SERCA) and a substantial loss of glycogen phosphorylase and glycogen debranching enzyme (AGL) in amylase-treated samples. Creatine kinase (CK) and pyruvate kinase (PK) contents were increased as a result of both …

Probing cardiac calcium regulation using time-resolved optical spectroscopy.
Sarcoplasmic reticulum calcium adenosine triphosphatase (SERCA) is an integral membrane Ca2+ pump that reuptakes Ca2+ into the lumen of sarcoplasmic reticulum (SR), decreases the cytoplasmic Ca2+ concentration, and initiates relaxation in both skeletal and cardiac muscle. In the heart, SERCA …

The effects of fatigue on glycogen, glycogen phosphorylase, and calcium uptake associated with the sarcoplasmic reticulum of rat skeletal muscle
… causes muscle contraction. The SR Ca²⁺-adenosine triphosphatase (ATPase) drives the translocation of two Ca²⁺ ions into the SR, utilizing the energy derived from the hydrolysis of one adenosine triphosphate (ATP) molecule. The process of SR Ca²⁺ uptake causes muscle relaxation. It has …

The Role of a Neuron-Specific V-ATPase in Synapse Specification, Function, and Maintenance
The Vacuolar-type (V-) adenosine triphosphatase (ATPase) is a proton-pumping nanomachine consisting of two multi-subunit, reversibly associating protein sectors, the cytosolic V1 sector and the membrane-bound Vo sector. The V1/Vo holoenzyme hydrolyses ATP to translocate protons across biological …

Age-related changes in renal function, membrane metabolism, transporter activity and abundance in hypokalemic Fischer 344 x Brown-Norway F1 rats
… in BLM as well as NHE-3 in BBM was determined. Adenosine triphosphatase (ATPase) activity was measured in membrane vesicles and three microdissected segments of the nephron (proximal convoluted tubule [PCT], cortical collecting tubule [CCT], and medullary collecting tubule [MCT]). In both age …

Nuclear and Plasma Membrane Properties of Macrophage Heterokaryons and Hybrids
… and is also rich in a divalent cation dependent adenosine triphosphatase (ATPase) activity. The melanoma cell lacks these macrophage membrane markers. High yields of mouse macrophage-melanoma cell heterokaryons and macrophage-macrophage homokaryons were obtained through the Sendai virus-induced …
