5. 4. Real-time PCR for diagnosis of botulism and quantification of neurotoxin gene expression in Clostridium botulinum

   Författare :Ingrid Artin; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; detection; qRT-PCR; Clostridium botulinum; molecular methods;

   Sammanfattning : The objectives of the work presented in this thesis have been to develop molecular methods for (i) detection of Clostridium botulinum in food and clinical samples, and (ii) monitoring the expression of the neurotoxin gene, cnt, during different growth phases and under different growth conditions. For the diagnosis of botulism, a real-time PCR-based method including an internal amplification control for C. LÄS MER

7. 5. Drug purity determination by capillary electrophoresis : Practical and theoretical aspects on peak shape and resolution

   Författare :Olle Stålberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : Capillary electrophoresis was used for separation and determination ofdrugs. Structural analogues, enantiomers and rotamers were separated usingderivatized β-cyclodextrins and γ-cyclodextrins as selectors.In order to improve these separation systems different kinds of chargedamphiphiles were introduced in the background electrolyte (BGE).
