Electrophysiology tools

Attention must be paid to the viability of the exeised tissue under in vitro conditions. Electrophysiologic characterization appears to be a valuable tool to indicate the viability of the tissue following excision. The viability of the tissue can be retained by continuous bubbling with O2/CO2 mixtures and addition of glucose to the buffer medium [11]. [Pg.210]

Using superfusion experiments, electrophysiological techniques, pithed animal preparations, and experiments in which transmitter release was determined indirectly via the end-organ response (e.g., twitch response of vas deferens preparations), numerous presynaptic opioid receptors have been identified (Table 2). For the identification of the receptors, classical drug tools were used for future studies, knockout mice (now available for each of the four opioid receptor subtypes) and special nucleotides (e.g., antisense oligodeoxynucleotides or short interfering... [Pg.412]

Many examples of inhibitory presynaptic neuropeptide Y receptors have been found in tissues from experimental animals and humans (Table 3), based on experiments with each of the four techniques described in the Introduction (overflow experiments, electrophysiological techniques, pithed animals, electrically induced twitches in isolated tissues). For the identification of the receptors, the three peptides and modified (e.g., truncated) congeners (Figure 4) were the only tools for many years. More recently, selective antagonists (e.g., in the study by Schwertfeger et al. [2004] on the human heart) and knockout mice (e.g., in the study by Smith-White et al. [2002] on the mouse heart) have been used. According to most studies, only Y2 receptors serve as presynaptic neuropeptide Y receptors. [Pg.423]

Our second section enters deep into electrophysiology. The electrochemistry is here a tool, but a remarkable one in which use is made of electrodes so thin that they can be inserted into the brain without damage. Here, they provide information on one of the neurotransmitters, dopamine, and what happens to it once it has been produced in a pulse from a neuron. [Pg.467]

Fluorescein angiography, ocular blood flow analysis via laser Doppler flowmetry, color vision measurements, contrast sensitivity testing, and electrophysiological tests (e.g., pattern electroretinograms) are used as research tools in the evaluation of POAG patients. Routine clinical use is not advocated at this time. [Pg.423]

The formation of cardiomyocytes within the murine EB provided investigators with a unique in vitro tool for the investigation of early cardiomyogenesis. Detailed ultra-structural, immunohistochemical, molecular, and electrophysiological studies showed that the developmental stages of the ES-derived cardiomyocytes in vitro parallel those of the in vivo murine heart [49-53]. [Pg.299]
