1. 6. Structural features underlying antigen presentation by the non-classical MHC class Ib molecule Qa-1b

   Master-uppsats, KTH/Proteinvetenskap

   Författare :Lejla AI-Tamimi; [2022]
   Nyckelord :immune checkpoint; NKG2A; MHC class Ib; Qdm; antibody; crystal structure;

   Sammanfattning : Blockering av NKG2A receptorn på NK - och CD8+ T celler med en anti-NKG2A antikropp, medför en aktivering av cytolytisk aktivitet, och är en lovande immunkontrollpunkt i immunterapi mot cancer. Nyligen har en TCR-liknande antikropp, EXX1, som binder till liganden för NKG2A receptorn, Qa-1b - en icke-klassisk MHC klass Ib molekyl i möss -studerats i tumör modeller in vitro. LÄS MER

3. 7. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Thi Hoai Thu Trinh; [2022]
   Nyckelord :dye-affinity chromatography; single-layer cryogels; double-layer cryogels; protein purification; bovine serum albumin; biochemistry; Chemistry;

   Sammanfattning : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. LÄS MER

4. 8. Structure-based design of new antiviral substances against the Venezuelan equine encephalitis virus

   Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

   Författare :Elin Öberg; [2022]
   Nyckelord :x-ray crystallography; protein crystallization; Venezuelan equine encephalitis virus; structure-based drug design; applied biochemistry; Technology and Engineering;

   Sammanfattning : The Venezuelan equine encephalitis virus (VEEV) is a highly infectious alphavirus responsible for severe outbreaks and epidemics in the Americas. The nonstructural protein 2 (nsP2) cysteine protease plays a fundamental role in the VEEV replication process, and is therefore, an attractive drug target for structure-based drug design using x-ray crystallography.

5. 9. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction

   Master-uppsats, KTH/Kemiteknik

   Författare :Caroline Kihlbom; [2021]
   Nyckelord :Solvent extraction; cobalt-nickel separation; CYANEX 272; pregnant leach solution; cobalt sulphate; Vätskevätskeextraktion; kobolt-nickel separation; CYANEX 272; laklösning; koboltsulfa;

   Sammanfattning : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. LÄS MER

7. 10. Resolving temporal links between the Högberget granite and the Wigström tungsten skarn deposit in Bergslagen (Sweden) using trace elements and U-Pb LA-ICPMS on complex zircons

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Anders Plan; [2020]
   Nyckelord :Bergslagen; Wigström; Högberget; geochronology; geochemistry; U-Pb; REE; trace element; zircon; hydrothermal zircon; LA-ICPMS; SEM; skarn; tungsten; wolfram; scheelite; deposit; ore; critical raw material; Earth and Environmental Sciences;

   Sammanfattning : Combined U-Pb and REE trace element LA-ICPMS analyses were performed on zircons, from the scheelite-bearing Wigström skarn, associated micro-granitic dykes and the highly evolved parental Högberget (sensu stricto) granite. Combined systematic of zircon typology and microtextures, trace elements and isotopic chemistry suggest the presence of several diverse zircon types, spanning from early- to late- magmatic stage into a hydrothermal stage.
