  1. 1. The structure and conformation of saccharides determined by experiment and simulation

    Author : Roland Stenutz; B. Meyer; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Abstract : A computer program, CASPER, for sequence determination of oligosaccharides and regular polysaccharides using NMR-data, has been extended to support multiply branched structures. The program has been modified to allow the use of incomplete experimental data since spectral overlap can be a problem even at high fields. READ MORE

  2. 2. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies

    Author : Carsten Meyer-Jacob; Richard Bindler; Hendrik Vogel; Jan Karlsson; John F. Boyle; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Fourier transform infrared spectroscopy; visible-near infrared spectroscopy; PLS regression; biogenic silica; climate change; carbon cycling; lake-water quality; geochemistry; paleolimnology; Holocene; Lake El’gygytgyn; Torneträsk;

    Abstract : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. READ MORE

  3. 3. Cataract induced by UVR-B 300nm : Characterization and genetic modulation of the lens sensitivity to oxidative stress

    Author : Linda Maren Meyer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Lens; cataract; ultraviolet radiation; oxidative stress; Grx1; interleukins;

    Abstract : Cataract is defined as an opacification of the lens resulting in visual impairment. Worldwide, it is the number one cause of blindness and there are currently no strategies to prevent the onset of the disease. Cataract surgery is the most commonly performed elective intervention in industrialized countries. READ MORE

  4. 4. Cataract from ultraviolet radiation in the mouse

    Author : Linda Maren Meyer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Lens; cataract; ultraviolet radiation; oxidative stress; mouse; light scattering;

    Abstract : Cataract is defined as an opacification of the crystalline lens that results in visual impairment, Cataract is the number one cause of blindness in the world and there are currently no strategies to prevent it. Extraction of cataractogenous lenses is the most commonly performed surgical intervention in industrialized countries. READ MORE

  5. 5. Immunogenetic variation along the latitudinal gradient in Scandinavian anuran species : Evolutionary processes, demography and infection

    Author : Maria Cortazar-Chinarro; Jacob Höglund; Anssi Laurila; Yvonne Meyer-Lucht; Helena Westerdahl; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biologi; Biology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : The evolutionary and demographic processes affecting how genetic variation is partitioned and distributed over large geographical scales is of fundamental importance for our understanding of how organisms may adapt to their environments. Northern peripheral populations generally have lower genetic variation and individuals in these populations may therefore face difficulties adapting to their local environment. READ MORE
