Sammanfattning : Impulses coming from peripheries are modified in the spinal cord and transmitted to the brain. Several neurotransmitters have been involved in the processing of impulses in the spinal dorsal horn. Acetylcholine (ACh) is one of many neurotransmitters involved in the regulation of nociception in the spinal cord. LÄS MER
2. Extended-release metoprolol : studies on the drug release and pharmacokinetics of a multiple-unit formulation
Sammanfattning : .... LÄS MER
Sammanfattning : Controlled-release formulations reduce the frequency of injections and better maintain plasma concentrations within the therapeutic window. Poly(D,L-lactide-co-glycolide) (PLG) is currently the most frequently used biodegradable polymer for this application. LÄS MER
4. Metal Particles – Hazard or Risk? Elaboration and Implementation of a Research Strategy from a Surface and Corrosion Perspective
Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. LÄS MER
Sammanfattning : In recent years there has been a growing interest and increased intensity of research in the area of edible films and coatings. Edible films and coatings can improve quality and shelf-life of food products by acting as barriers to e.g. moisture and oxygen, hence preventing dehydration and oxidative reactions. LÄS MER
