  1. 1. Caspase-3 in lens epithelium

    Författare :Nooshin Talebizadeh; Per Söderberg; Finn Hallböök; Konstantin Galichanin; Michael Wormstone; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultraviolet radiation; caspase-3; lens; cataract; apoptosis; Immunohistochemistry; spatial distribution; time evolution; modelling; automatic analysis; cell counting; image analysis.; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Purpose: To model the time evolution of active caspase-3 protein expression in a healthy lens, and in a lens exposed to UVR-300 nm (UVR-B). To develop an automated method to classify the fluorescent signal of biomarkers in the lens epithelial cells.Methods: Six-week old Sprague-Dawley rats were used. LÄS MER

  2. 2. MULTIFOCAL SPHERICAL FISH LENSES

    Författare :Yakir Gagnon; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multifocal Lens; Adaptation; Dispersion; Spherical lens; Model; Fish; Ray-trace; Longitudinal Chromatic Aberration; Longitudinal Spherical Aberration; Modulation Transfer Function; Point Spread Function; Refractive Index Gradient;

    Sammanfattning : Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. LÄS MER

  3. 3. Control of early development of the lens and the retina

    Författare :Tanushree Pandit; Lena Gunhaga; Paola Bovolenta; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lens; retina; BMP; FGF; chick; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The nervous system is composed of two separate compartments, the central and the peripheral nervous system. The peripheral nervous system (PNS) composed mainly of sensory organs transmits sensory information to the central nervous system (CNS) comprising the brain and the spinal cord. LÄS MER

  4. 4. Cystatin C in the Eye and in Specific Model Systems

    Författare :Johan Wasselius; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; protein uptake; ciliary body; lens; cornea; retina; eye; Cystatin C; cathepsin B; Oftalmologi;

    Sammanfattning : It is a necessity of life to make proteins, and it is an equal necessity to degrade those proteins, to eliminate dysfunctional proteins, and leave room for new ones. The processes of protein synthesis and degradation into peptides - proteolysis - have attracted a great interest during the last decades. LÄS MER

  5. 5. Business Intelligence through a sociomaterial lens : The imbrication of people and technology in a sales process

    Författare :Tobias Christian Fischer; Einar Iveroth; Jan Lindvall; Mathias Cöster; Christina Keller; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; big data; business intelligence; business intelligence systems; data analytics; digital transformation; imbrication; sales process; sociomateriality; sociomaterial imbrication model; work shadowing;

    Sammanfattning : Digitalization and digital devices are on the rise, and as a result, many new products and services have been developed, which has led to greater interaction between people and technology. This thesis explores the interaction between people and technology by looking at the daily use of a business intelligence (BI) system in an automotive company’s sales process, where sellers use the system to analyze, report, and measure sales performance.
