  1. 1. The clinical value of genetic analyses of bone and soft tissue tumors

    University dissertation from Division of Clinical Genetics, Lund University

    Author : Charles Walther; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016]

    Abstract : Tumors of bone and soft tissue are common but only constitute 1 % of all malignant tumors. The malignant tumors are often difficult to diagnose due to their rarity and morphological resemblance between subtypes. This makes the diagnostic process challenging. READ MORE

  2. 2. Analysis of Electrocardiograms Using Artificial Neural Networks

    University dissertation from Department of Clinical Physiology, Lund University

    Author : Bo Hedén; Lund University.; Lunds universitet.; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; Lead reversal.; Myocardial infarction; Computer-assisted; Expert system; Electrocardiography; ECG-diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Most conventional ECG interpretation programs use decision tree logic for interpretation of the ECG. The performance is generally good but can be improved. Artificial neural networks represent a new computer method, which has proved to be of value in pattern recognition and classification tasks. READ MORE

  3. 3. Source localisation of epileptiform activity in epilepsy of temporal lobe origin

    University dissertation from Clinical Neurophysiology

    Author : Göran Lantz; Lund University.; Lunds universitet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; frequency analysis; ictal; singe photon emission computed tomography; volume conduction; extracranial; intracranial; LORETA; dipole; source localisation; epilepsy; mesolimbic; Fast Fourier Transform; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : In patients with drug resistant partial epilepsy, who are under consideration for epilepsy surgery, interictal and ictal EEG recorded with extracranial electrodes plays an important role in the localisation of the seizure onset area. During the past years, methods have been developed, which can be used to estimate the location of the source of epileptiform activity in the brain from extracranial EEG data. READ MORE

  4. 4. Signal identification for visual electrophysiological recordings. A comparison of signal analysis techniques and their application to clinical electrophysiology of vision

    University dissertation from Göteborg : University of Gothenburg

    Author : Thomas Wright; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Visual Electrophysiology; Signal detection; Signal-to-Noise Ratio; multivariate analysis; spatial-temporal partial least-squares;

    Abstract : Aims: The aim of this thesis was to investigate the use of objective methods for the analysis of visual electrophysiological recordings. Specifically can signal identification algorithms identify electrophysiological signals and can they be applied to improve clinical testing and analysis? Methods: Automated signal identification algorithms were applied to multifocal electroretinogram (mfERG) and visual evoked potential (VEP) recordings. READ MORE

  5. 5. Vitamin A and Osteoporosis Experimental and Clinical Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara Johansson; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; vitamin A; bone; osteoporosis; Invärtesmedicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin;

    Abstract : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. READ MORE
