4. 22. Proteomic strategies for blood biomarker development in rare dystrophinopathies

   Author : Camilla Johansson; Cristina Al-Khalili Szigyarto; Ola Söderberg; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Duchenne muscular dystrophy; Becker muscular dystrophy; proteomics; affinity-proteomics; biomarkers; DIA-MS; SRM-MS; immunoassay; suspension bead arrays; Duchenne muskeldystrofi; Becker muskeldystrofi; proteomik; affinitetsproteomik; biomarkörer; DIA-MS; SRM-MS; immunoassay; suspension bead array; Biotechnology; Bioteknologi;

   Abstract : Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are two rare genetic disorders of the family dystrophinopathy. They are both caused by the lack of, or reduced production of, the protein dystrophin. READ MORE

5. 23. Chemical labelling methods for gel free based proteomics

   Author : Åsa Wåhlander; Institutionen för immunteknologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; 2D-HPLC; isotopes; labelling; proteomics; mass spectrometry;

   Abstract : In this thesis different aspects of gel free procedures for mass spectrometry based proteome analysis are addressed, with emphasis on labelling techniques. It is based on three original articles where the effects imposed onto peptides upon modification are investigated, and the development of a new type of labelling strategy is described. READ MORE

6. 24. Levulinic Acid : Versatile Building Block for Plasticizer Design

   Author : Wenxiang Xuan; Minna Hakkarainen; Karin Odelius; Rafael Auras; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; levulinic acid; plasticizer; polylactide; migration; degradation; antibacterial;

   Abstract : The utilization of renewable resources is a challenging and an importantaspect towards development of sustainable plastic products. Therefore,commercial biomass conversion to produce biobased chemicals isnecessary to replace current fossil-based chemicals. READ MORE

7. 25. Microwave heating effects on degradation and migration of additives from polypropylene packaging

   Author : Jonas Alin; Minna Hakkarainen; Jiebing Li; Anna Finne Wistrand; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

   Abstract : The effect of different food types, polymer qualities and microwaves on the overall and specific migration during microwave heating of plastic packaging was investigated to better understand the packaging-food interactions and the effect of microwaves on food packaging. This work focuses on the migration of chemical compounds to food simulants from commercially available polypropylene packages. READ MORE
