21. Development of positron emission tomography radioligands for the dopaminergic and serotonergic neurotransmission systems
Abstract : The dopaminergic and serotonergic neurotransmission systems are of central interest in relation to several neuropsychiatric disorders. The main objectives were to develop new suitable radioligands for positron emission tomography (PET) examinations of the dopamine transporter (DAT) as well as the serotonin 5-HT1A and 5-HT2A-receptors.

24. Studies of Micellar Electrokinetic Chromatography as an Analytical Technique in Pharmaceutical Analysis - an Industrial Perspective
Abstract : Studies have been performed to evaluate the use of micellar electrokinetic chromatography (MEKC), one mode of capillary electrophoresis (CE), as an analytical technique in industrial pharmaceutical analysis. The potential for using chemometrics for the optimisation of MEKC methods has also been studied as well as the possibilities of coupling MEKC with mass spectrometry (MS). READ MORE

25. Glutathione transferases : markers for renal disease
Abstract : Glutathione transferases (GST) alpha and pi were purified to homogeneity and used to develop immunochemical methods for analysis of the amount of these proteins in human urine. The methods were employed for diagnosis of renal dysfunctions caused by drugs and industrial chemicals. READ MORE
