1. Blood-Brain Barrier Transport : Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies
Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE

2. Quantitative Aspects of Nanodelivery Across the Blood-Brain Barrier : Exemplified with the Opioid Peptide DAMGO
Abstract : The use of nanocarriers is an intriguing approach in the development of efficacious treatment for brain disorders. The aim of the conducted research was to evaluate and quantify the impact of a liposomal nanocarrier formulation on the brain drug delivery. READ MORE

3. Pericyte Influence on Drug Delivery Across the Blood-Brain Barrier : Implications for Therapy of Neurodegenerative Diseases
Abstract : The blood-brain barrier (BBB) represents a complex interface between the brain parenchyma and systemic blood circulation, strictly controlling exchange of substances between the two sites. Pericytes are mural cells located on the abluminal membrane of the brain endothelium, involved in BBB formation and maintenance. READ MORE

4. Peptide-based delivery to glioblastoma cells studied by the blood-brain barrier model
Abstract : Crossing the blood-brain barrier (BBB) is a great challenge for delivery of highly charged macromolecules such as nucleic acids and proteins to the brain. Cell-penetrating peptides (CPPs) are promising vectors to deliver various cargoes ranging from small molecules to large molecules such as antibodies, proteins, and nucleic acids. READ MORE

5. Pathophysiology of blood-brain barrier, brain edema and cell injury following hyperthermia : New role of heat shock protein, nitric oxide and carbon monoxide : an experimental study in rat using light and electron microscopy
Abstract : This thesis deals with the molecular mechanisms of hyperthermia induced brain damage in rats. The results clearly establish that hyperthermia caused by 4 h heat stress at 38° C is associated with a breakdown of the blood-brain barrier (BBB) permeability which seems to be instrumental in causing brain edema and cell injury.
