  2. 1. Exploring mechanisms of peer effects in education : Frame factor analyses of classroom instruction

    Author : Pontus Bäckström; Jesper Boesen; Charlotta Mellander; Jan-Eric Gustafsson; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Despite a vast international literature, previous research into compositional effects and peer effects in education has remarked on the lack of consensus within the field. To date, peer effects in education and students’ different opportunities to learn in school have been studied separately. READ MORE

  4. 2. The hematopoietic transcription factor RUNX1 : a structural view

    Author : Stefan Bäckström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; RUNX1; Runt domain; CBFβ; transcription factor; leukaemia; protein crystallography; anomalous diffraction; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylärbiologi; Molecular Biology;

    Abstract : The malfunction of the transcriptional regulator RUNX1 is the major cause of several variants of acute human leukemias and its normal function is to regulate the development of the blood system in concert with other transcriptional co-regulators. RUNX1 belongs to a conserved family of heterodimeric transcription factors that share a conserved DNA binding domain, the Runt domain (RD), named after the first member of this group – Runt - found in Drosophila melanogaster.

  5. 3. Super resolution fluorescence imaging : analyses, simulations and applications

    Author : Jan Bergstrand; Jerker Widengren; Eilon Sherman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Fluorescence methods offer extraordinary sensitivity and specificity, and are extensively used in the life sciences. In recent years, super resolution fluorescence imaging techniques have developed strongly, uniquely combining ~10 nm sub diffraction resolution and specific labeling with high efficiency. READ MORE

  6. 4. Genetic, molecular and functional analyses of factor I - an inhibitor of the complement system

    Author : Sara Nilsson; Malmö Proteinkemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atypical hemolytic uremic syndrome; deficiency; Complement inhibition; factor I; renal disease;

    Abstract : Factor I (FI) is a serine protease that inhibits the complement system by cleaving activated C3 and C4 complement proteins, in the presence of cofactors. Mutations in the gene coding for FI have been identified in complete FI deficient- and atypical hemolytic uremic syndrome (aHUS) patients. READ MORE

  7. 5. THE ANDROGEN RECEPTOR GGN POLYMORPHISM. Genetic and functional analyses

    Author : Kristina Lundin; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Functional domain; Genetic predisposition; Reproductive function; Sex hormone; Transactivation function; Repeat; Polymorphism; Androgen receptor; Transcription factor; Medicin människa och djur ; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : Male sex development and reproductive function is regulated by androgens acting via the androgen receptor (AR). The AR harbours two polymorphic repeats of CAG and GGN triplets, encoding glutamines and glycines, respectively. READ MORE
