  1. 1. Muscarinic receptors and urinary bladder selectivity : Properties that determine the organ selectivity of compounds

    Författare :Staffan Sundquist; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; bladder; muscarinic; receptor subtypes; smooth muscle; multivariate; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Sammanfattning : Urinary bladder contraction is mainly mediated by activation of muscarinic acetylcholine receptors (mAChR). Muscarinic antagonists are often effective in treatment of unstable bladder. The effectiveness of this treatment has often been limited by side effects as dry mouth. LÄS MER

  3. 3. On the Autonomic Control of Blood Flow and Secretion in Salivary Glands. Functional and morphological aspects on muscarinic receptor subtypes in different species

    Författare :Anders Ryberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Muscarinic receptor subtype; neuronal; non-neuronal; expression; secretion; blood flow; salivary gland; human; rat; sheep;

    Sammanfattning : Parasympathetic nervous activity is the principal stimulus for evoking fluid responses within salivary glands. Concomitantly to the onset of this response, the blood flow increases. LÄS MER

  4. 4. Development of in vitro and ex vivo positron-emitting tracer techniques and their application to neurotrauma

    Författare :Sven Sihver; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Short-lived radionuclides; in vitro receptor binding; in vitro and ex vivo autoradiography; positron emission tomography; benzodiazepine; muscarinic acetylcholine; and NMDA receptors in CNS; experimental neurotrauma; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : The use of positron-emitting tracers has been extended beyond tomographic facilities in the last few years, giving rise to a general positron-emitting tracing technique. The methodological part of the present thesis involved the evaluation of the performance of storage phosphor (SP) plates, with tracers labeled with high-energy, short-lived, positron-emitting radionuclides, using homogenized tissue specimens and autoradiography with frozen brain sections.

  5. 5. Muscarinic M1 and M4 receptor subtypes in normal and patjhological conditions in the central nervous system : Studies on human and animal tissues using subtype selective ligands

    Författare :Ezra Mulugeta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Snake venoms from different mamba species contain toxins that bind to muscarinic acetylcholine receptors (mAChR). The toxins MT-1 (selective for M1 after iodination), M1 toxin-1 (also known as MT7, selective for MI) and M4 toxin-1 (also known as MT3, selective for M4 receptors) were isolated and used to study M1 and M4 receptor subtypes in normal and pathological conditions.
