1. 1. Intracellular unbound drug concentrations : Methodology and application for understanding cellular drug exposure

   Författare :André Mateus; Per Artursson; Pär Matsson; José A. G. Morais; Jeff Krise; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular unbound drug concentrations; free drug; drug binding; drug transport; drug accumulation; cellular drug response; drug target engagement; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : Most known drug targets and metabolizing enzymes are located inside cells. Interactions with these proteins are determined by intracellular unbound drug concentrations. Assessing intracellular drug exposure is technically challenging, but essential for predicting pharmacokinetic, pharmacological, and toxicological profiles of new drugs. LÄS MER

3. 2. Heterogeneity of leukemic cells with regard to daunorubicin accumulation and efflux : potential role in drug resistance

   Författare :Eva Knaust; Linköpings universitet; []
   Nyckelord :Drug resi stance. acute myeloid leukemia; flow cytometry; gene expression; transport kinetics; apoptosis; MEDICINE; MEDICIN;

   Sammanfattning : Cellular resistance to chemotherapy is a major cause of treatment failure in acute myelocytic leukemia (AML) and other malignancies. Drug resistance is multifactorial; the most studied mechanism being multidrug resistance (MDR), mediated by the P-glycoprotein (PPG), a transmembrane transport protein with a pump function, encoded by the mdr 1 gene.

4. 3. Liposomes for Drug Delivery : from Physico-chemical Studies to Applications

   Författare :Nill Bergstrand; Katarina Edwards; Felix M Goni; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liposome; steric stabilisation; BNCT; cryo-TEM; EGF; targeting; stability; permeability; pH-sensitive liposomes; triggered release; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : Physico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. LÄS MER

5. 4. Safety and Efficacy Modelling in Anti-Diabetic Drug Development

   Författare :Bengt Hamrén; Mats O Karlsson; Eric Snoeck; Uppsala universitet; []
   Nyckelord :Pharmaceutical biosciences; pharmacokinetic; pharmacodynamic; mechanism-based; modelling; type 2 diabetes mellitus; tesaglitazar; PPAR; drug development; NONMEM; Farmaceutisk biovetenskap;

   Sammanfattning : A central aim in drug development is to ensure that the new drug is efficacious and safe in the intended patient population. Mathematical models describing the pharmacokinetic-pharmacodynamic (PK-PD) properties of a drug are valuable to increase the knowledge about drug effects and disease and can be used to inform decisions.

7. 5. Synthesis of Polymeric Nanocomposites for Drug Delivery and Bioimaging

   Författare :Heba Asem; Joydeep Dutta; Moustapha Hassan; Fei Ye; Jöns Hilborn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biodegradable polymers; SPION; QDs; drug delivery; cytotoxicity; MRI; in vivo fluorescence imaging; biodistribution; Fysik; Physics;

   Sammanfattning : Nanomaterials have gained great attention for biomedical applications due to their extraordinary physico-chemical and biological properties. The current dissertation presents the design and development of multifunctional nanoparticles for molecular imaging and controlled drug delivery applications which include biodegradable polymeric nanoparticles, superparamagnetic iron oxide nanoparticles (SPION)/polymeric nanocomposite for magnetic resonance imaging (MRI) and drug delivery, manganese-doped zinc sulfide (Mn:ZnS) quantum dots (QDs)/ SPION/ polymeric nanocomposites for fluorescence imaging, MRI and drug delivery.
