  1. 1. Prevention of cervical cancer in countries with high and low incidence of the disease

    Author : Susanna Alder; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cervical cancer is to a large extent a preventable disease, through prophylactic human papillomavirus (HPV) vaccination and cervical cancer screening. Still, it is the second most common cancer among women in Argentina, with unchanged mortality rates for the last 30 years, due to the absence of organized screening. READ MORE

  2. 2. Determination of Antibiotics in the Swedish Environment with Emphasis on Sewage Treatment Plants

    Author : Richard Lindberg; Barbro Andersson; Mats Tysklind; Magnus Johansson; Alfredo Alder; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; antibiotics; environment; sewage treatment plants; antibiotika; miljö; avloppsreningsverk; Environmental chemistry; Miljökemi;

    Abstract : Metoder har utvecklats för att kunna bestämma tolv antibiotikasubstanser, vanliga inom human medicin, i miljöprover. Fokus lades på trimetoprim samt substanser från följande grupper: fluorokinoloner, sulfonamider, penicilliner, cefalosporiner, nitroimidazoler, tetracykliner samt makrolider. READ MORE

  4. 4. Computational Studies and Design of Biomolecular Diels-Alder Catalysis

    Author : Mats Linder; Tore Brinck; Kendall N. Houk; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Computational chemistry; density functional theory; enzyme design; molecular modeling; organocatalysis; stepwise Diels-Alder; oxyanion hole;

    Abstract : The Diels-Alder reaction is one of the most powerful synthetic tools in organic chemistry, and asymmetric Diels-Alder catalysis allows for rapid construction of chiral carbon scaffolds. For this reason, considerable effort has been invested in developing efficient and stereoselective organo- and biocatalysts. READ MORE

  5. 5. Developments in the Field of Aza-Diels-Alder Reactions, Catalytic Michael Additions and Automated Synthesis

    Author : Stefan Modin; Pher Andersson; Lars Engman; Hans Adolfsson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Asymmetric synthesis; aza-Diels-Alder; Michael addition; Transfer hydrogenation; automated synthesis; Catalysis; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : The development of new aza-bicyclic structures with potential applications as ligands synthesised via an aza-Diels-Alder cycloaddition has been studied. The studies are concerning the i) development of large scale aza-Diels-Alder reaction, ii) development of a fast and simple route to bicyclic diamine ligands, iii) development of new aza-Diels-Alder adducts from different dienes, iv) development and application of bicyclic N,P ligands for catalytic Michael additions and v) development of robotized asymmetric transfer hydrogenation reactions.
