Serotonin Uptake and Serotonin Uptake Inhibition
Annals of the New York Academy of Sciences, 1990Serotonin uptake carriers occur on serotonin neurons, on glial cells and on blood platelets. The uptake carrier on serotonin neurons inactivates serotonin that has been released into the synaptic cleft by transporting it back into the nerve terminal. The serotonin uptake carrier is the means by which blood platelets acquire serotonin, since they do not

Brain tissue has a remarkable ability to accumulate glutamate. This ability is due to glutamate transporter proteins present in the plasma membranes of both glial cells and neurons. The transporter proteins represent the only (significant) mechanism for removal of glutamate from the extracellular fluid and their importance for the long-term maintenance

Adenosine is a purine nucleoside and modulates a variety of physiological functions by interacting with cell-surface adenosine receptors. Under several adverse conditions, including ischemia, trauma, stress, seizures and inflammation, extracellular levels of adenosine are increased due to increased energy demands and ATP metabolism. Increased adenosine

An elderly patient was known with generalised osteoarthritis and destruction of the right hip. Six months before, this patient was admitted to a general hospital because of oedema and ventricular tachycardia. No coronary artery disease was found on coronary angiogram and the tachycardia was successfully converted to sinus rhythm.

Uptake of [35S]lipoate was studied in perfused rat liver and in isolated rat hepatocytes. During single-pass perfusion of [35S]lipoate about 30% of the radioactivity is retained in the liver. A substantial amount of 5,5'-dithiobis(2-nitrobenzoic acid)-reactive material appears in the effluent perfusate, while hepatic efflux of GSH is unchanged.

AbstractMuscular exercise requires transitions to and from metabolic rates often exceeding an order of magnitude above resting and places prodigious demands on the oxidative machinery and O2‐transport pathway. The science of kinetics seeks to characterize the dynamic profiles of the respiratory, cardiovascular, and muscular systems and their ...

KNOWLEDGE of how oxygen is transported from the ambient air to the tissue cells of the body is essential to an understanding of the mechanisms by which the body adapts to the oxygen demands of muscular exercise. The requirement of oxygen by the various tissue cells of the body is met by the combined cardiovascular and pulmonary systems, which function ...

The specific uptake size index for quantifying radiopharmaceutical uptake
Physics in Medicine and Biology, 2004Quantitative indices of radionuclide uptake in an object of interest provide a useful adjunct to qualitative interpretation in the diagnostic application of radionuclide imaging. This note describes a new measure of total uptake of an organ, the specific uptake size index (SUSI). It can either be related in absolute terms to the total activity injected

Glutamate is an excitatory neurotransmitter widely used in the vertebrate central nervous systems. The synaptic transmission process is characterized by three steps: (1) presynaptic vesicular transmitter uptake, (2) presynaptic release, and (3) postsynaptic receptor activation.

Calcium transporters that mediate the removal of Ca(2+) from the cytosol and into internal stores provide a critical role in regulating Ca(2+) signals following stimulus induction and in preventing calcium toxicity. The vacuole is a major calcium store in many organisms, particularly plants and fungi. Two main pathways facilitate the accumulation of Ca(
