1. 21. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food

   Författare :Tien Hoac; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; Copper; Zinc; Oxidative stability; Thioredoxin reductase; Glutathione peroxidase; Selenoproteins; Milk; Selenium supplementation; Technological sciences; Teknik;

   Sammanfattning : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. LÄS MER

3. 22. Development of GC-HRMS procedures for determination of naturally occuring polar compounds in various environmental applications

   Författare :Bodil Widell; Dag Broman; Caroline Leck; Joan Grimalt; Stockholms universitet; []
   Nyckelord :GC-HRMS; steroid hormones; amino acids; perch; size-resolved aerosol; Arctic; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The overall objectives of this dissertation were to gain further understanding of the two following environmentally significant issues: (i) Determination of natural steroid hormones in blood plasma from perch (Perca fluviatilis) during a reproductive cycle and to evaluate the possibility of using the steroid composition as a biomarker for early signs of endocrine disruptive effects. (ii) Determination of dissolved free amino acids in size resolved airborne particles collected over the Arctic pack ice area (>80°N) in summer and to study their overall relationship with the ocean surface microlayer as a potential source.

4. 23. Carbon Nitride : Characterization and Protein Interactions

   Författare :Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. LÄS MER

5. 24. Improved titanium and steel implants : Studies on bisphosphonate, strontium and surface treatments

   Författare :Paula Linderbäck; Pentti Tengvall; Per Aspenberg; Håkan Engqvist; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Purpose: The general aim of this thesis was to increase the understanding of biomaterial surface modifications and local delivery of osteoporosis drugs for bone integration. We therefore (i) characterised and investigated model surface coatings for controlled drug delivery in a rat tibia screw model (ii) elucidated the effect of surface treatment for activation of complement system in vitro.

7. 25. Capillary-Driven Microfluidic Devices for Sample Preparation of Bio-Medical Specimens

   Författare :Janosch D. Hauser; Niclas Roxhed; Göran Stemme; Charles Mace; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Sample preparation is an integral part of bio-medical analysis routines, as it makes specimens of interest compatible with downstream instrumentation. Correct and proper sample preparation is of critical importance for reliable analysis results. LÄS MER
