1. 31. Insights into the small intestinal colloids and their impact on drug solubility

   Författare :Albin Parrow; Christel A.S. Bergström; Per Larsson; Outi Salo-Ahen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Oral administration is the preferred route for drug delivery because it has high patient compliance and is cost effective. The aqueous solubility of modern drug candidates is often poor, but a drug delivered orally must dissolve in the intestine so that it can be absorbed into the circulation. LÄS MER

3. 32. Aspects of fluid therapy in the critically ill. Experimental and clinical studies on fluid therapy in the inflammatory conditions

   Författare :Svajunas Statkevicius; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation; plasma volume; fluid resuscitation; crystalloids; colloids; albumin;

   Sammanfattning : Patients suffering from inflammatory conditions often present with severe hypovolemia due to vasodilatation and increased vascular permeability. Early administration of fluids is, therefore, a cornerstone and lifesaving therapy.However, a vigorous and aggressive fluid therapy increases tissue edema, worsen tissue perfusion and organ function.

4. 33. Origin of Iron Isotope Signatures in Boreal Estuaries

   Författare :Sarah Conrad; Magnus Mörth; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Sammanfattning : The geochemistry of iron (Fe) during freshwater transport and estuarine mixing has been investigated. Espescially the changes in the Fe-isotope signature have been studied. The fate of Fe-isotopes during estuarine mixing has been poorly studied. LÄS MER

5. 34. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

   Författare :Maxime Bergman; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microgels; Lysozyme; eye lens proteins; confocal microscopy; interaction potential; phase behaviour; simulations;

   Sammanfattning : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. LÄS MER

7. 35. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

   Författare :Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

   Sammanfattning : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. LÄS MER
