Parathyroid Hormone and Mitochondrial Respiration
Endocrinology, 1964Parathyroid hormone added in vitro stimulates anion-dependent respiration in isolated liver and kidney mitochondria. This response depends upon Mg++ (or Mn++) and substrate and is inhibited by uncouplers and inhibitors of electron transport but not by oligomycin or triethyltin, inhibitors of oxidative phosphorylation.

Mitochondrial Respiration and Oxygen Tension
2017Measurements of respiration and oxygen tension in plant organs allow a precise understanding of mitochondrial capacity and function within the context of cellular oxygen metabolism. Here we describe methods that can be routinely used for the isolation of intact mitochondria, and the determination of respiratory electron transport, together with ...

Cellular Control of Mitochondrial Respiration
1976Oxygen delivery to tissues is essential for maintaining the oxygen tension at a level adequate to sustain the cellular energy supply via oxidative phosphorylation. The question is then how the cell regulates oxidative phosphorylation and, through this, the rate of oxygen consumption.

Uncoupling of mitochondrial respiration by ADP
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977Even when oxidative phosphorylation is blocked completely by addition of high concentrations of oligomycin plus aurovertin, the addition of ADP to a suspension of mitochondria containing a high concentration of ATP inside the mitochondria induces a stimulation of respiration and oxidation of nicotinamide nucleotide.

Effect of peritonitis on mitochondrial respiration
Journal of Surgical Research, 1971Abstract Rats were exposed to a lethal form of Klebsiella pneumoniae peritonitis and the mitochondrial respiration of their livers was studied either 18 hours after the injection of the organism or immediately after clinical death. No indication of impaired mitochondrial function was found compared to normal controls. The level of high-energy adenine

Effects of ferric nucleotides on mitochondrial respiration
Archives of Biochemistry and Biophysics, 1964Abstract Addition of ferric adenosine diphosphates to rat liver mitochondria induced a burst of respiration similar to that given by ADP. The ratio of moles of added Fe(III)ADP to gram-atoms of oxygen removed during this burst was 20% greater than in the corresponding case with ADP.

Control of Mitochondrial Respiration in the Heart In Vivo
Annual Review of Physiology, 1989The role of the hydrolysis products of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and inorganic phosphate (Pi), in the control of myocardial respiration was evaluated in vivo using 31P NMR. These studies were conducted to evaluate whether increases in the ATP hydrolysis products can be detected through the cardiac cycle or during ...

Mitochondrial respiration measurement
Protocol Exchange, 20071. Isolate mitochondria by gently crushing 40 to 80 flies in a 10 ml Kontes homogenizer with 7 strokes of the pestle in 3 ml homogenization buffer consisting of 225 mM mannitol, 75 mM sucrose, 10 mM MOPS, 1 mM EGTA, 0.5% BSA, pH 7.2 at 4°C 38. 2. Filter the extracts through 8 layers of cheese cloth, and then centrifuge at 300 x G for 3 min in a Beckman

In Vivo Studies of Mitochondrial Respiration
1978In the course of an investigation of adding new collateral blood flow to the cortex of ischemic patients, the point was raised as to whether an increase in cortical oxygen tension would lead to improved oxygen utilization and energy production. If so, this might at least partially supply an explanation for improved neurologic function.

Methanethiol inhibition of mitochondrial respiration
Toxicology and Applied Pharmacology, 1977Abstract Methanethiol and other alkylthiols appear to be at least partly responsible for fetor hepaticus, the unpleasant breath-odor of comatose patients with severe liver disease. We have found that methanethiol strongly inhibits rat liver mitochondrial respiration.
