16. Skin barrier responses to moisturizers
Sammanfattning : Moisturizers are used in various types of dry skin disorders, but also by people with healthy skin. It is not unusual that use of moisturizers is continued for weeks, months, or even years. LÄS MER
17. Novel Metal-Mediated Organic Transformations : Focusing on Microwave Acceleration and the Oxidative Heck Reaction
Sammanfattning : Transition metals have played an important role in synthetic organic chemistry for more than a century, and offer catalytic transformations that would have been impossible with classical chemistry. One of the most useful and versatile of the transition metals is palladium, which over the years has catalyzed many important carbon-carbon forming reactions. LÄS MER
18. Nutrition in infancy - Clinical studies on dietary intake, metabolism and growth
Sammanfattning : Nutrition in infancy - Clinical studies on dietary intake, metabolism and growth Our aims were to try to determine an appropriate formula protein concentration to be used during the second half of infancy and to evaluate the effects on plasma lipids when breast milk was exchanged for formula and/or weaning foods. Both aspects were studied with special regard to the influence of traditional weaning foods. LÄS MER

20. Flexible Synthesis of Rigid Cyclophanes - Synthesis and derivatisation of 2,7-diaza-1,2,3,6,7,8-hexahydropyrene into chiral macrocycles
Sammanfattning : Rigid, chiral and amphiphilic cyclophanes of potential use as biomimetic host molecules were prepared by cyclic dimerisation of chiral diamino building blocks with amino-reactive cross-linking reagents. A reliable synthesis of the scaffold 2,7-diaza-1,2,3,6,7,8-hexahydropyrene was developed. LÄS MER
