  2. 1. Mechanisms of muscarinic feedback regulation of acetylcholine release in rat hippocampus : an in vitro study

    Author : Öie Nordström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The present study on dilute suspensions of synaptosomes from rat hippocampus yields evidence that feedback regulation of acetylcholine release in this preparation is exerted by a muscarinic autoreceptor localized on the cholinergic nerve ending itself.A possible model for the sequence of events which may take place at the cholinergic nerve ending is presented.

  4. 2. Exploring Cancer Drugs In Vitro and In Vivo : With Special Reference to Chemosensitivity Testing and Early Clinical Development

    Author : Anne von Heideman; Peter Nygren; Bengt Tholander; Rolf Larsson; Seija Grénman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxic drug; in vitro assay; drug development; phase I clinical trial; Oncology; Onkologi; Oncology; Onkologi;

    Abstract : The aims of this thesis were to investigate the utility of in vitro drug sensitivity testing to optimize the use of cancer chemotherapy and to assess the properties of a new cancer drug in a phase I clinical trial. Tumour cells from patients were analysed with the short-term Fluorometric Microculture Cytotoxicity Assay (FMCA). READ MORE

  5. 3. Development of nicotinic receptor ligands for positron emission tomography - from in vitro to in vivo : Binding studies of neuronal nicotinic acetylcholine receptors using different ³H-, ¹1C- and `6Br - labeled ligands

    Author : Wiebke Sihver; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; nicotinic acetylcholine receptor; PET-ligand; in vitro; in vivo; Alzheimer s disease; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : Neuronal nicotinic acetylcholine receptors (nAChRs) are involved in central processes, such as cognitive functionand memory, and play a critical role in neuropathological changes in Alzheimer's disease (AD). The in vivocharacterization of nAChRs by positron emission tomography (PET) may increase our understanding of thefunctional implications of these receptors in AD and their early changes during this disease.

  6. 4. In Vitro – In Vivo Correlation of Injectable Lipid Formulations

    Author : Lars Söderberg; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EC 50; erythrocyte; human plasma; lipid injectable formulation; IVIVC; fatty acid; in vitro release; Peripheral nerve block; neurolytic; structure-activity;

    Abstract : In order to develop new pharmaceuticals, to optimize pharmacotherapy and secure patient safety, documentation of the properties of pharmaceutical formulations is a most important process. A significant practical problem associated with pre-clinical evaluation of lipophilic substances with pharmacological properties is their low aqueous solubility. READ MORE

  7. 5. Comparative in vivo and in vitro studies on the biomechanics of maxillary partial dentures. A methodological and experimental study

    Author : Cláudio Pinheiro Fernandes; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stomatology; biomechanics; Bite force; conical crowns; denture design; in vitro; in vivo; photoelasticity; strain gauges; Odontology; stress analysis.; Odontologi;

    Abstract : Biomechanical aspects are generally agreed to be significant, particularly during the planning of restorative treatments and the design of prosthetic appliances. However, comparative in vivo/in vitro studies show wide differences in the magnitudes and patterns of functional strains in prosthetic devices. READ MORE
