  1. 21. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Author : Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE

  2. 22. Wound Infection Following Coronary Artery Bypass Graft Surgery : Risk Factors and the Experiences of Patients

    Author : Christine Leo Swenne; Marianne Carlsson; Christina Lindholm; Jan Borowiec; Annika Ekbom Schnell; Hans Rutberg; Uppsala universitet; []
    Keywords : Caring sciences; coronary artery bypass graft; surgical wound infection; infection control; risk factor; blood glucose; postoperative; Saphenous vein harvesting; wound evaluation scale; mediastinitis; psychology; quality of life; Vårdvetenskap;

    Abstract : The primary aim was to register the incidence of surgical wound infections (SWI) in sternotomy and leg incisions and potential risk factors for SWI following coronary artery by-pass graft (CAGB) procedures. Patients’ perspectives of SWI and the subsequent treatment were also considered. Risk factors were registered for 374 patients. READ MORE

  3. 23. Clinical probability assessment and biochemical markers in the diagnosis of deep vein thrombosis

    Author : Johan Elf; Malmö Klinisk koagulationsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Venous thrombosis; APC-PCI complex.; D-Dimer; Clinical probability; Diagnosis;

    Abstract : The combination of pre-test clinical probability assessment and D-dimer test is now widely applied in the diagnostic process of DVT. The general objective of the present investigation was to validate these results in a Swedish routine emergency setting were the prevalence of the disease is high and were the clinical probability assessment was handled by many junior physicians.

  4. 24. On Hardware Implementation of Discrete-Time Cellular Neural Networks

    Author : Suleyman Malki; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit switching; Network on Chip; Vein feature extraction; Velocity measurement; Discrete-Time Cellular Neural Network; Switched broadcast; Serialized broadcast; Cellular Neural Network; Field- Programmable Gate-Array; Image processing.;

    Abstract : Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. READ MORE

  5. 25. Conduction Disturbances in Patients with Atrial Fibrillation

    Author : Eva Hertervig; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Pulmonary Vein Potentials; Atrial Fibrillation; Conduction Disturbances;

    Abstract : Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. READ MORE
