  2. 1. Proteins of the Inter-α-inhibitor Family : Biosynthesis, Plasma Clearance and Interaction with Extracellular Matrix Components

    Author : Aneta Kaczmarczyk; Erik Fries; Anders Malmström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; bikunin; inter-α-inhibitor; pre-α-inhibitor; intracellular processing; plasma clearance; extracellular matrix; binding; collagen; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Bikunin, a chondroitin sulfate-containing protein of 25 kDa, has protease inhibitory activity and occurs in the plasma in free and complexed form. In inter-α-inhibitor (IαI) and pre-a-inhibitor (PαI) it is covalently linked through its chondroitin sulfate (CS) chain to two or one other polypeptide of about 80 kDa – heavy chains 1 and 2 (H1, H2) and heavy chain 3 (H3) – respectively.

  6. 4. Oxidative dissolution of UO2 by α-radiolysis

    Author : Niklas Hansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen effect; kinetics; MOX; α-radiolysis; dose rate; UO2; ε-particles;

    Abstract : To prevent the spread of radiotoxic nuclides in the environment, spent nuclear fuel generated by decades of nuclear power operation must be safely stored for at least 100 000 years. The KBS-3 method is a highly developed deep geological repository concept and is the first final repository design for high-level nuclear waste to be constructed. READ MORE

  7. 5. New Methodologies in Organic Chemistry: Applications to the Synthesis of α-Amino Acids and Natural Products

    Author : Sebastian Hirner; Peter Somfai; Varinder Aggarwal; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic synthesis; 2-Vinylaziridines; 3-Pyrrolines; Ringexpansion; Rearrangement; Anisomycin; Total synthesis; α-Amino acids; Arylglycines; Weinreb amides; α-Arylation; Grignard reagents; Umpolung; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the development and application of new synthetic methodology in organic chemistry. The first part describes the development of a new protocol for the synthesis of 3-pyrrolines by means of a microwave-assisted ring-expansion reaction of 2-vinylaziridines. READ MORE
