  1. 1. Wrist osteoarthritis : causes, treatment and outcome

    Författare :Elin Swärd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Wrist osteoarthritis is rare compared to osteoarthritis in the finger joints or thumb base and affects younger patients. Its etiology is heterogenous, and osteoarthritis may be caused by traumatic injuries, as well as by nontraumatic medical conditions. LÄS MER

  4. 3. Parameter Estimation - in sparsity we trust

    Författare :Johan Swärd; Statistical Signal Processing Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; Sparse models; Convex optimization; Symbolic Periodicity; Alternating direction method of multipliers ADMM ; Covariance fitting; multi-pitch estimation problem; Off-grid estimation; Dictionary learning; Atomic norm; Sampling schemes;

    Sammanfattning : This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. LÄS MER

  5. 4. Modulation of the calcium-force relationship in smooth muscle by polyamines and metabolic inhibition

    Författare :Karl Swärd; Cellulär biomekanik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic inhibition; polyamines; excitation-contraction coupling; smooth muscle; intracellular calcium; Physiology; Fysiologi;

    Sammanfattning : The relationship between intracellular free calcium ([Ca2+]i) and force in smooth muscle was investigated in receptor-coupled permeabilized preparations and by fluorimetry of the calcium indicator Fura 2 in intact smooth muscle. The time integral of spontaneous [Ca2+]i transients in the intact rat portal vein was decreased by cyanide and, during tonic contraction, cyanide reduced force without changing [Ca2+]i implying metabolic sensitivity of both membrane excitation and [Ca2+]i - activation of the contractile proteins.

  7. 5. Knee injuries and their consequences – the impact of impact

    Författare :Per Swärd; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Anterior cruciate ligament (ACL) injuries are common, severe knee injuries that result in a high risk of developing knee osteoarthritis (OA) in the affected individuals. As proof of high impact forces applied to cartilage and bone at the time of injury, traumatic bone marrow lesions and osteochondral fractures, located predominantly in the lateral tibiofemoral compartment, are commonly associated with an ACL injury.
