  1. 1. 3D super-resolution microscopy of living cells using reversibly switchable fluorophores

    Författare :Andreas Bodén; Ilaria Testa; Francisco Balzarotti; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; 3D imaging; super-resolution; microscopy; reversibly switchable fluorescent proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Traditional optical microscopy techniques are limited in spatial resolution due to the wave nature of light. This means that neighboring objects separated by a distance smaller than about 200 nm cannot be distinguished. LÄS MER

  3. 2. Automated super-resolution microscopy for high-throughput imaging

    Författare :Xavier Casas Moreno; Ilaria Testa; Florian Jug; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; throughput; microscopy automation; nanoscopy; Biologisk fysik; Biological Physics;

    Sammanfattning : Fluorescence microscopes enable the visualization of biological samples with high contrast by labeling specific structures with fluorescent molecules. However, the spatial resolution of widely used microscopy techniques, such as widefield and confocal microscopy, is limited by the size of a focused spot of light, which roughly corresponds to half the wavelength of the illumination.

  4. 3. Determinants of Depressive Symptoms in Adolescents : The Role of Sexual Harassment and Implications for Preventive Interventions

    Författare :Heléne Zetterström Dahlqvist; Katja Gillander Gådin; Evelina Landstedt; Viveka Östberg; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Depressive symptoms; Adolescence; School; Public Health; Sexual harassment; Personal relative affluence; Gender theory; Ecosocial theory; Cognitive-behavioral; Preventive interventions;

    Sammanfattning : Background: Depression is considered the worldwide leading cause of illness and disability in young people and an urgent public health issue. Within the field of public health it is of interest to deepen the understanding of determinants of depressive symptoms (DS) that are possible to address on a political or an organizational level.

  5. 4. Collagen VI - Molecular Assembly and Interactions

    Författare :Charlotte Wiberg; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical biology; extracellular matrix; glycosaminoglycan; proteoglycan; collagen; biglycan; decorin; Klinisk biologi;

    Sammanfattning : The extracellular matrix plays an integral role in tissue remodeling and development and it defines the different mechanical properties of a variety of connective tissues. Its complexity in composition and the details in organization has only been partly elucidated. LÄS MER

  7. 5. Laminin G Domains, their Receptors, and Activation of Intracellular Pathways

    Författare :Hao Yu; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; cell-matrix interaction; signaling; receptor; Basement membrane; laminin;

    Sammanfattning : Basement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. LÄS MER
