  1. 1. Synthetic analogs of sialyl Lewis x

    Författare :Ulf Ellervik; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stereoselective synthesis; regioselective synthesis; lactam analogs; lactone; Selectin; Sialyl Lewis x; SLex; Organic chemistry; Organisk kemi;

    Sammanfattning : The sialyl Lewis x (SLex) tetrasaccharide is the smallest recognizable ligand for selectins. The selectins constitute a vital part of the inflammatory cascade for recruitment of leukocytes to a site of tissue damage or microbial infection. LÄS MER

  3. 2. Expression and interaction studies of recombinant human monoclonal antibodies

    Författare :Daniel X Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The highly specific binding characteristics of monoclonal antibodies (mAbs) have made them one of the most useful tools in the fields of research and biotechnology where they provide the basis for a large number of diagnostic and technical assays. In recent years, with the advent of techniques to generate fully human antibodies, mAbs have also emerged as a new important class of therapeutics. LÄS MER

  4. 3. Aspects of locomotor evolution in the Carnivora (Mammalia)

    Författare :Ki Andersson; Lars E. Holmer; Lars Werdelin; Margaret E. Lewis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; Mammalia; Carnivora; Locomotion; Cranial; Elbow joint; Morphology; Morphometrics; Landmarks; Multivariate statistics; Allometry; Ecomorphology; Dental; Body size; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Sammanfattning : In this thesis, the shape of the distal humerus trochlea is analysed using landmark-based morphometrics and multivariate methods, with the aim of exploring locomotor evolution in carnivorans. Elbow joint morphology is used together with body size and craniodental morphology to characterize past and present carnivorans. LÄS MER

  5. 4. Paleoglaciology of the Tian Shan and Altai Mountains, Central Asia

    Författare :Robin Blomdin; Arjen P. Stroeven; Clas Hättestrand; Jonathan M. Harbor; Lewis Owen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; glacial geomorphological mapping; cosmogenic nuclide dating; Tian Shan; Altai Mountains; Physical Geography; naturgeografi;

    Sammanfattning : The mountain-systems of Central Asia, act as barriers to atmospheric circulation patterns, which in turn impose striking climate gradients across the region. Glaciers are sensitive indicators of climate change and respond to changes in climate gradients over time by advancing during cold and wet periods and receding during warm and dry periods. LÄS MER

  7. 5. Crystallization of Metal Fluoride Hydrates from Mixed Acid Solutions

    Författare :Kerstin Forsberg; Åke Rasmuson; Alison Lewis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crystallization; crystal growth; b-FeF3.3H2O; iron fluoride trihydrate; CrF3.3H2O; pickling; pickle bath; hydrofluoric acid; nitric acid; stainless steel; Chemical engineering; Kemiteknik;

    Sammanfattning : In this work crystal growth and nucleation of b-FeF3×3H2O and crystallization of chromium (III), iron (III) and nickel (II) fluoride hydrates from mixed acid (1-3 mol/kg HNO3 and 1-6 mol/kg free HF) have been investigated. The solubility of b-FeF3×3H2O has been determined in solutions of different hydrofluoric acid (1-7mol/ kg) and nitric acid (0-7mol/ kg) concentrations at 30, 40 and 50°C. LÄS MER
