1. 1. Ultra-short-chain perfluoroalkyl acids : Environmental occurrence, sources and distribution

   Författare :Maria Björnsdotter; Ingrid Ericson Jogsten; Anna Kärrman; Leo W. Y. Yeung; Tom Harner; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFASs; TFA; TFMS; point sources; precursors; solar radiation; atmospheric oxidation; atmospheric deposition; flux; Arctic;

   Sammanfattning : Ultra-short-chain perfluoroalkyl acids (PFAAs) is a group of highly fluorinated and very stable chemicals. Their small molecular structure in combination with the acidic functional group result in highly polar compounds and concern has been raised as these substances may threaten our drinking water supplies.

3. 2. Role of nuclear receptors in the regulation of human adipose tissue metabolism

   Författare :Prasad G. Kamble; Jan W Eriksson; Ingrid Dahlman; Uppsala universitet; []
   Nyckelord :human adipose tissue; nuclear receptors; glucocorticoids; estrogen; PPARγ; lipocalin 2; glucose uptake; lipolysis; adipogenesis; genotype-based recall;

   Sammanfattning : Nuclear receptors modulate expression of genes involved in adipose tissue (AT) metabolism. Their improved understanding may provide new treatment options for metabolic disorders such as obesity, insulin resistance (IR) and type 2 diabetes (T2D). LÄS MER

4. 3. Advances in Mass Spectrometry for the Analysis of Emerging Persistent Organic Pollutants

   Författare :Lauren Gayle Mullin; Leo W. Y. Yeung; Ingrid Ericson Jogsten; Jean-François Focant; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Liquid Chromatography; Supercritical Fluid Chromatography; Ion Mobility; POPs; Electrospray Ionization;

   Sammanfattning : Mass spectrometry (MS) is a technique widely implemented for the measurement of environmental pollutants. A critical tool for the analysis of persistent organic pollutants (POPs) over several decades, MS as coupled with liquid and gas chromatography (LC and GC) techniques enables the analysis of emerging POPs.

5. 4. Early life experiences and alcohol use in youth : An emerging role of the Vesicular Glutamate Transporters

   Författare :Maria Vrettou; Erika Comasco; Ingrid Nylander; Kent W. Nilsson; Åsa Wallén-Mackenzie; Roberto Ciccocioppo; Uppsala universitet; []
   Nyckelord :alcohol; early-life stress; brain; early adulthood; expression; DNA methylation; glutamate; Vesicular Glutamate Transporters;

   Sammanfattning : Initiation of alcohol consumption usually takes place during adolescence, a period characterized by a plethora of physical and emotional changes. Towards early adulthood, hazardous drinking patterns can emerge and potentially lead to the development of Alcohol Use Disorder (AUD). LÄS MER

7. 5. NMR Self-Diffusion Studies and Stability Studies of Emulsions

   Författare :Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

   Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER
