1. 1. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

   Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

3. 2. Clinical and experimental studies on oxidized fragrance terpenes as contact allergens

   Författare :Johanna Bråred Christensson; Göteborgs universitet; []
   Nyckelord :autoxidation; contact allergy; limonene; linalool; colophonium; limonene-1-hydroperoxide; limonene-2-hydroperoxide; 15-hydroperoxyabietic acid; 15-HPA; terpenes; local lymph node assay; LLNA; Freunds complete adjuvant test; FCAT; patch testing; laser Doppler imaging; skin irritation; visual reading;

   Sammanfattning : The work presented in this thesis aims to improve the possibilities for diagnosing contact allergy to oxidized limonene and linalool and to, in patients, study contact allergy from structurally closely related hydroperoxides with regard to their specificity, potency and cross-reactivity. The fragrance terpenes limonene (from citrus oil) and linalool (from lavender oil) are widely used in household and industrial products. LÄS MER

4. 3. Electrical impedance related to experimental induced changes of human skin and oral mucosa

   Författare :Ingrid Nicander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :bioengineering; dielectric properties; electrical impedance; irritation; non-invasive; oral mucosa; skin; skin barrier; stratum comeum; stratum corneum lipids;

   Sammanfattning : There is a need for an objective and non-invasive method for assessing reactions in the human skin and oral mucosa, particularly for weak reactions. During the past few decades, several methods of measuring irritant responses have indeed been developed for the skin and to some extent also for the oral mucosa. LÄS MER

5. 4. Indoor Environment in Dwellings and Sick Building Syndrome (SBS) : Longitudinal Studies

   Författare :Bo Sahlberg; Dan Norbäck; Berndt Stenberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Indoor environment; sick building syndrome SBS ; dwelling; longitudinal cohort study; building dampness; mould; microbial volatile organic compounds MVOC ; biomarkers; asthma; risk factors; Arbets- och miljömedicin; Occupational and Environmental Medicine;

   Sammanfattning : People spend most of their time indoors and mostly in the dwelling. It is therefore important to investigate associations between indoor exposure in dwellings and health. Symptoms that may be related to the indoor environment are sometimes referred to as the "sick building syndrome" (SBS). LÄS MER

7. 5. Dental restorative materials from a work environmental perspective

   Författare :Emma-Christin Lönnroth; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Sammanfattning : The main occupational health hazard for dental personnel is muscle-skeletal problem, followed by symptoms caused by exposure to chemicals. Clinical dental work includes exposure to a number of products like soap, detergents, disinfectants, amalgam, mono- and oligomers, catalysts, inhibitors, solvents and adhesives. Some are chemically very active. LÄS MER
