1. 21. Examining neurobehavioral effects of chemosensory exposure to local irritants using event related potentials

   Författare :Stephanie Anja Juran; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The aim of this thesis was to examine whether unpleasant odors disturb cognitive task performance. At first glance, it seems intuitive that for example the smell of fire smoke would immediately interrupt my current writing at the computer. LÄS MER

3. 22. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases

   Författare :Georgina Chávez; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross linked enzyme aggregates.; caprolactone; perhydrolase; Lipase B from Candida antarctica;

   Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

4. 23. Solubility and polymorphism of molecular compounds

   Författare :Sandra Gracin; Åke C. Rasmuson; David J. W. Grant; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; solubility; prediction of solubility; UNIFAC; activity coefficients; activity of the solid phase; polymorphism; controlled crystallization; sonication.; Kemiteknik; Chemical engineering; Kemiteknik;

   Sammanfattning : This thesis deals with the controlled crystallization of small organic molecules and is focused on solubility and polymorphism. The solubility was determined for phenylacetic acid, p-hydroxyphenylacetic acid, p-aminophenylacetic acid, p-hydroxybenzoic acid and ibuprofen in both water and in a range of organic solvents.

5. 24. The discovery of antiviral compounds targeting adenovirus and herpes simplex virus : assessment of synthetic compounds and natural products

   Författare :Mårten Strand; Göran Wadell; Mikael Elofsson; Ya-Fang Mei; Lieve Naesens; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virology; antiviral; adenovirus; herpes simplex virus; small molecule; inhibitor; hsv; drug discovery; medicinsk virologi; Medical Virology; datorlingvistik; computational linguistics; mikrobiologi; Microbiology;

   Sammanfattning : There is a need for new antiviral drugs. Especially for the treatment of adenovirus infections, since no approved anti-adenoviral drugs are available. Adenovirus infections in healthy persons are most often associated with respiratory disease, diarrhea and infections of the eye. These infections can be severe, but are most often self-limiting.
