1. 1. Drug Delivery to the Brain by Liposomes : Understanding Factors Governing Delivery Outcomes In Vivo

   Författare :Yang Hu; Margareta Hammarlund-Udenaes; Teresa Dalla Costa; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanocarrier; liposome; blood-brain barrier; brain delivery; formulation; methotrexate; diphenhydramine; microdialysis; pharmacokinetics; model-based approach; Farmaceutisk vetenskap; Pharmaceutical Science; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

   Sammanfattning : The blood-brain barrier (BBB) is the primary obstacle for efficient drug delivery to the central nervous system (CNS). One promising strategy to enhance brain delivery is to utilize nanocarriers (NC), e.g., liposomes, encapsulating CNS drugs. LÄS MER

3. 2. Rational modifications of cell-penetrating peptides for drug delivery : Applications in tumor targeting and oligonucleotide delivery

   Författare :Maarja Mäe; Ülo Langel; Edvard Smith; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptide; oligonucleotide; drug delivery; tumor targeting; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Sammanfattning : High molecular weight biomolecules are becoming important in the development of new therapeutics. However, their size and nature creates a major limitation for their application – poor penetration through biological membranes. LÄS MER

4. 3. Translational Tumor Drug Delivery : Doxorubicin formulation performance, intracellular uptake and molecular diffusion

   Författare :Oliver Degerstedt; Hans Lennernäs; Erik Sjögren; Per Hansson; Jessica Rosenholm; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; doxorubicin; drug diffusion; cellular uptake; drug delivery; PBPK modelling; hepatocellular carcinoma; emulsion; IC50; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Globally, hepatocellular carcinoma (HCC) is the most common form of liver cancer and a leading cause of cancer death. One important risk factor is liver cirrhosis and the disease progression is characterized by deposition of extracellular matrix proteins that form a fibrous network, which increases liver stiffness and may limit the effectiveness of different treatment strategies.

5. 4. Nasal Drug Delivery : In Vitro Studies on Factors Influencing Permeability and Implications on Absorption

   Författare :Cecilia Wadell; Frans Merkus; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

   Sammanfattning : Nasal delivery is a feasible alternative to oral or parenteral administration for some drugs because of the high permeability of the nasal epithelium, rapid drug absorption across this membrane and avoidance of hepatic first-pass metabolism. The main objective of this thesis was to investigate factors influencing the permeability of the nasal mucosa to various compounds and to evaluate implications for drug absorption via the nasal route.
