1. 16. Common mechanism for teratogenicity of antiepileptic drugs : Drug-induced embryonic arrhythmia and hypoxia-reoxygenation damage

   Författare :Faranak Azarbayjani; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Atiepileptik drugs; embryonic heart; arrhythmia; cleft palate; ROS; antioxidants; Ikr; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

   Sammanfattning : The Antiepilptic drugs (AEDs) phenytoin (PHT), carbamazepine (CBZ), phenobarbital (PB), tri- and dimethadione (TMD and DMD) are known teratogens having a common malformation pattern in human and animal studies. This thesis was designed chiefly to test a hypothesis correlating the teratogenicity of these AEDs to episodes of pharmacologically induced embryonic arrhythmia and hypoxia-reoxygenation damage.

   Sammanfattning : Xanthine oxidase (EC 1.1.3.22) is one of the major enzymatic sources of oxygen-derived free radicals. LÄS MER

4. 18. Mutational analysis of melanocortin receptors 1 and 5

   Författare :Per-Anders Frändberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Melanocortin receptor; melanocortin peptide; MSH; NDP-MSH; mutagenesis human phenotype; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

   Sammanfattning : The melanocortin receptor family includes five subtypes, named MC1R to MC5R. Melanocortin receptors are predominantly coupled to second messenger pathway of cyclic AMP through coupling to G-protein. This study is focused on structure-function relationship of MC1R and MC5R.

5. 19. Enzymes in different pathways of bile acid biosynthesis

   Författare :Catrin Furster; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biochemistry; biokemi;

   Sammanfattning : Enzymes catalyzing side chain hydroxylations and dehydrogenation/isomerization in different pathways of bile acid biosynthesis were studied.Pig liver mitochondrial sterol 27-hydroxylase (CYP27A) was found to catalyze 24- and 25-hydroxylation of cholesterol in addition to the known 27-hydroxylation.

7. 20. Clinical Pharmacokinetics of the Antimalarial Artemisinin Based on Saliva Sampling

   Författare :Toufigh Gordi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Artemisinin; pharmacokinetics; saliva; HPLC; pharmacodynamics; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

   Sammanfattning : Artemisinin is the parent compound of a novel family of antimalarials. Repetitive administrations of artemisinin to both healthy volunteers and malaria patients have been shown to result in decreased plasma concentrations of the compound, most probably due to an autoinduction of different CYP450 enzymes.
