Glutamine transport in rat kidney mitochondria in metabolic acidosis.
In order to study factors regulating renal ammoniagenesis, the transport and metabolism of L-glutamine were studied in mitochondria from kidneys of control and acidotic rats. On incubation in 1 mM [(14)C]glutamine, there was production and accumulation of [(14)C]glutamate within the matrix space. However no [(14)C]glutamine was detected in the matrix space, even with 10 mM [(14)C]glutamine as s...

t, 2 X 10-3. n2 Therefore the condition for convergence of the perturbation series is by no means fulfilled, and in order to get a valid approximation, one would have to solve the secular equation. which would lead to nonlocalized states. Further work in this direction is in progress. The above considerations hold also for more extensive systems. It seems possible that they can be applied to bi...
متن کاملA Search for Mitochondrial Damage in Alzheimer’s Disease Using Isolated Rat Brain Mitochondria
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that affects regions of the brain that control cognition, memory, language, speech and awareness to one’s physical surroundings. The pathological initiation and progression of AD is highly complex and its prevalence is on the rise. In his study, Alzheimer's disease was induced with single injection of amyloid-β (Aβ) peptides (...

متن کاملComparative studies on glutamate metabolism in synpatic and non-synaptic rat brain mitochondria.
1. The apparent Michaelis constants of the glutamate dehydrogenase (EC 1.4.1.3), the glutamate-oxaloacetate transaminase (EC 2.6.1.1) and the glutaminase (EC 3.5.1.2) of rat brain mitochondria derived from non-synaptic (M) and synaptic (SM2) sources were studied. 2. The kinetics of oxygen uptake of both populations of mitochondria in the presence of a fixed concentration of malate and various c...
