1. 21. Analysis and human levels of persistent perfluorinated chemicals

   Författare :Anna Kärrman; Gunilla Lindström; Bert van Bavel; Ulf Järnberg; Jessika Hagberg; Lennart Hardell; Derek Muir; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; Chemistry; Kemi; Chemistry; Kemi;

   Sammanfattning : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. LÄS MER

3. 22. Human Fetal Hemoglobin : Biochemical Characterization and Recombinant Production

   Författare :Khuanpiroon Ratanasopa; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blood substitutes; HBOCs; HbF; recombinant hemoglobin; pseudoperoxidase; ITC; haptoglobin;

   Sammanfattning : Blood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. LÄS MER

4. 23. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics

   Författare :Konrad Thorsteinsson; Marta Bally; Hudson Pace; Gisa Gerold; Susan Daniel; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; supported lipid bilayer; binding kinetics; equilibrium fluctuation analysis; TIRF; FRET; norovirus; HSV; SARS-CoV-2; histo-blood group antigens; ApoE; heparan sulfate; mikrobiologi; Microbiology;

   Sammanfattning : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

5. 24. Antioxidant Capacity in Fruit and Vegetables -Cultivar Variation - Storage Conditions - Human Antioxidant Status

   Författare :Jessica Nilsson; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human plasma antioxidants; Brassica; strawberry; pea; cultivar; ABTS; FRAP; Total antioxidant capacity; TAC; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : The health-promoting effects of fruits and vegetables have been extensively discussed during the past decade since epidemiologic studies have shown relations between increased intake of fruit and vegetables and decreased incidences of several chronic diseases. It has been suggested that antioxidants are a main contributors to the observed effects, for example by acting as scavengers of free radicals. LÄS MER

7. 25. Biomarker detection via lab-on-a-chip integrated immunoaffinity approach for fluorescence and mass spectrometry readout

   Författare :Asilah Ahmad Tajudin; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; immunoaffinity; affinity prefractionation; immunoMALDI; solid-phase extraction; protein digestion; ISET; antibody microarray; signal amplification; fluorescence; microfluidics; lab on a chip; separation; acoustophoresis; ultrasound; acoustic radiation force; plasma; proteomics; MALDI mass spectrometry; immunoassay; porous silicon.;

   Sammanfattning : The blood/plasma protein biomarker profile represents the pathological and physiological changes relating to human diseases. However, the plasma proteome reflects a high degree of complexity that results in a challenge for most analytical methods in clinical diagnostics. LÄS MER
