  2. 1. Development of Methods for Assessing Unbound Drug Exposure in the Brain : In vivo, in vitro and in silico

    Author : Markus Fridén; Margareta Hammarlund-Udenaes; Ulf Bredberg; Yuichi Sugiyama; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Drug transport; Tissue distribution; Transporters; Pharmacokinetics; Other pharmacy; Övrig farmaci; Biopharmacy; Biofarmaci; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : The blood-brain barrier is formed by tightly joined capillary cells with transporter proteins and acts as to regulate the brain concentration of nutrients as well as many drugs. When developing central nervous system drugs it is necessary to measure the unbound drug concentration in the brain, i.e. the unbound brain exposure. READ MORE

  4. 2. Regulation of Renal Hyaluronan in Water Handling : Studies in vivo and in vitro

    Author : Sara Stridh; Peter Hansell; Mats Rundgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; water balance; fluid handling; diabetes; nephropathy; ACE fetopathy; reabsorption; hyaluronic acid; glycosaminoglycan; GAG; extracellular matrix; mTOR; rapamycin; streptozotocin;

    Abstract : Hyaluronan (HA) is a negatively charged extracellular matrix (ECM) component with water-attracting properties. It is the dominating ECM component in the renal medullary interstitium, where the amount changes in relation to hydration status: it increases during hydration and decreases during dehydration.

  5. 3. The Role of Chlamydia pneumoniae-induced Platelet Activation in Cardiovascular Disease : In vitro and In vivo studies

    Author : Hanna Kälvegren; Torbjörn Bengtsson; Arina Richter; Erik Kihlström; Kenneth Persson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia pneumoniae; Platelet; atherosclerosis; Infection; LDL-oxidation; Percutaneous coronary intervention; Cardiovascular disease; Serotonin; Reactive oxygen species production; Pharmacology; Farmakologi;

    Abstract : The common risk factors for atherosclerosis, such as obesity, high cholesterol levels, sedentary lifestyle, diabetes and high alcohol intake, only explain approximately 50% of cardiovascular disease events. It is thereby important to identify new mechanisms that can stimulate the process of atherosclerosis. READ MORE

  6. 4. Regulation of Ovarian Aromatase: Studies by Aromatase Assays in vitro and in vivo

    Author : Dmitrijus Kirilovas; Mats Brännström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; aromatase; human; granulosa cells; 11C-vorozole; active site; allosteric configuration; in vitro; in vivo; PET; androgens; rat; estrous cycle.; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Abstract : An in vitro method was developed for measuring aromatase, based on binding of competitive aromatase inhibitor [11C]vorozole to the active site of the enzyme. [11C]Vorozole displayed high, specific binding in vitro to human placenta and human granulosa cells (GC), both fresh and frozen/thawed cells, provided correct procedures were used. READ MORE

  7. 5. 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
