  1. 1. Secondary exposure to inhaled tobacco products

    Author : Matz Larsson; Scott M. Montgomery; Kjell Larsson; Bo Lundbäck; Luke Clancy; Örebro universitet; []
    Keywords : MEDICINE; MEDICIN; Medicine; Medicin;

    Abstract : Även andra individer än rökaren kan påverkas av tobaksrökning. Syftet med denna avhandling var att undersöka några sådana effekter. Studierna omfattar såväl passiv rökning som exponering under graviditet. READ MORE

  2. 2. Early Cambrian Problematic Lophotrochozoans and Dilemmas of Scleritome Reconstructions

    Author : Cecilia M Larsson; Lars E Holmer; Christian B Skovsted; Anette E S Högström; John S Peel; Glenn A Brock; Michael J Vendrasco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Problematica; scleritome; Trachyplax; tommotiid; Cambrian; South Australia; North Greenland; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The emergence and radiation of metazoan body plans around the Precambrian/Cambrian boundary, some 500-600 million years ago, seems to be concordant with the appearance and diversification of preservable hard parts. Several Precambrian soft-bodied, multicellular organisms most likely represent stem-group bilaterians, but their fossil record is rather sparse. READ MORE

  3. 3. Palladium-catalyzed C-H functionalization of alkenes under oxidative conditions

    Author : Johanna M Larsson; Kálmán Szabó; Eszter Borbas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : The unique properties of high oxidation state palladium have been used to develop new catalytic alkene C-H functionalization reactions. A Heck-type coupling based on the reactivity of palladium catalysts and diaryliodonium salts has been developed with broad synthetic scope and tolerance for functional groups that are ordinarily reactive in Pd0/PdII catalysis, for example, allylic acetates and aryl bromides.

  4. 4. Predictors of bone fragility in older women. Associations in older women between risk medications and measurements of physical function, bone microstructure and fracture risk

    Author : Berit A M Larsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteoporosis; risk prediction; fracture; risk medication; selective serotonin reuptake inhibitors; statins; physical function; timed up and go; one leg standing test;

    Abstract : Bone fragility with fractures constitutes a growing public health concern, resulting in suffering and major health care cost. This thesis project has been carried out by means of studies based on the SUPERB cohort of 75–80-year-old women from Gothenburg. READ MORE

  5. 5. Transition metal-catalyzed allylic and vinylic functionalization : Method development and mechanistic investigations

    Author : Johanna M. Larsson; Kálmán J. Szabó; Dennis G. Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; catalysis; Heck reaction; C-H functionalization; allylic substitution; silylation; borylation; trifluoromethylation; fluorination; mechanistic study; transition metal; alkene; allylic silane; allylic boronate; allylic fluoride; organisk kemi; Organic Chemistry;

    Abstract : The use of small molecule building blocks in, for example, pharmaceutical research and new material development, creates a need for new and improved organic synthesis methods. The use of transition metals as mediators and catalysts opens up new reaction pathways that have made the synthesis of completely new compounds possible as well as greatly improved the synthetic routes to known compounds.
