  2. 6. Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model

    Author : Barbara Elmståhl; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiography; Computed tomography; toxicity; Contrast media; Glomerular filtration; Gadolinium; Iodine; Kidney failure; Nephrotoxicity.; Medicin människa och djur ; radiology; Clinical physics; Medicine human and vertebrates ; tomography; medical instrumentation; Diagnostik; Diagnostics; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi;

    Abstract : Purpose: To confront the statement that gadolinium contrast media (Gd-CM) are less nephrotoxic than iodine contrast media (I-CM) when used in x-ray angiographic and computed tomographic (CT) examinations. Methods: I) For CT measurements (mean density in Hounsfield numbers) 20-mL syringes filled with I- and Gd-CM at 0.01, 0.02, 0. READ MORE

  4. 7. Online Combinatorial Optimization under Bandit Feedback

    Author : Mohammad Sadegh Talebi Mazraeh Shahi; Alexandre Proutiere; Vianney Perchet; KTH; []
    Keywords : Combinatorial Optimization; Online Learning; Multi-armed Bandits; Sequential Decision Making; Matematik; Mathematics; Datalogi; Computer Science;

    Abstract : Multi-Armed Bandits (MAB) constitute the most fundamental model for sequential decision making problems with an exploration vs. exploitation trade-off. In such problems, the decision maker selects an arm in each round and observes a realization of the corresponding unknown reward distribution. READ MORE

  5. 8. The neuropeptide VIP and the IL-6 family of cytokines in bone : effects on bone resorption, cytokine expression and receptor signalling in osteoblasts and bone marrow stromal cells

    Author : Emma Persson; Ulf Lerner; Andreas Kindmark; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; osteoblast; bone resorption; cytokines; IL-6; neuropeptides; VIP; transcription factor; Cell biology; Cellbiologi;

    Abstract : Bone tissue is continuously degraded and rebuilt to respond to the needs of the body. Cells of the osteoblast lineage are responsible for the formation of bone, whereas the resorption of bone tissue is carried out by osteoclasts. READ MORE

  6. 9. Hyponatremia - Early differential diagnosis, management and prognosis

    Author : Karin Olsson; Kardiovaskulär forskning - hypertoni; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyponatremia; differential diagnosis; Biomarkers; apelin; vasopressin; Prognosis and survival; bioreactance;

    Abstract : Abstract Hyponatremia is the most common electrolyte imbalance. It is associated with increased morbidity and in-hospital mortality. An effective early management is dependent on knowledge of epidemiology in the current population, accurate assessment of patient volume status and efficient diagnostic investigation. READ MORE

  7. 10. Biomarkers and viral risk factors in multiple sclerosis

    Author : Jesse Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Multiple sclerosis (MS) is a chronic inflammatory disease resulting in axonal injury and demyelination of nerve fibers in the central nervous system. The causal factor and pathological mechanisms governing disease progression have remained elusive, limiting the available clinical tools for MS diagnosis and treatment monitoring, particularly in the periphery.
