1. 16. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

   Författare :Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER

3. 17. Bacterial Vaginosis : Diagnosis, Prevalence, and Treatment

   Författare :Katarina Eriksson; Per-Göran Larsson; Urban Forsum; Ann-Sofie Adolfsson; Inger Mattsby-Baltzer; Linköpings universitet; []
   Nyckelord :Bacterial vaginosis; prevalence; diagnosis; PAP-smear; probiotic treatment; clindamycin; MEDICINE; MEDICIN;

   Sammanfattning : Bacterial Vaginosis (BV) is a disorder of unknown etiology, characterized by a foul smelling vaginal discharge, loss or reduction of the normal vaginal Lactobacilli, and overgrowth of other anaerobic bacteria. Thus, it presents a formidable problem for clinicians as well as microbiologists researching its etiology, clinical course, treatment, and epidemiology. LÄS MER

4. 18. Contact fatigue and crack propagation studies of sintered PM steel

   Författare :Anders Holmberg; Åsa Kassman Rudolphi; Urban Wiklund; Johan Ahlström; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; PM steel; Fatigue; Crack Initiation; Crack Propagation; Material Analysis; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Sammanfattning : Gears made of PM steel are of interest for the automotive industry because from the press/sinter route, complex geometries can be produced to near net shape with only a few processing steps while keeping the material and energy usage at a minimum. However, the PM steels of today have significant performance limitations caused by the inherent porosity which impairs the mechanical properties by acting as stress raisers in the material. LÄS MER

5. 19. Modulation of neutrophil extracellular trap formation in health and disease

   Författare :Ava Hosseinzadeh; Constantin F. Urban; Carol Munro; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; Candida albicans; Adenosine; Tempol; Nicotine; molekylärbiologi; Molecular Biology;

   Sammanfattning : The critical prompt innate immune response is highly built upon the influx of neutrophils from the blood stream to the site of infection. In the battlefield, neutrophils sense pathogen-associated molecular patterns (PAMPs) through their pattern-recognition receptors (PRRs) to launch a number of responses with the goal to defeat the invading pathogen.

7. 20. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers

   Författare :Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; pediatrics; exercise; Holter; water immersion; arrhythmia; clinical physiology; ECG; heart rate variability; heart rate response; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; pediatrik; Pediatrics;

   Sammanfattning : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.
