2. 1. Interpretation of diagnostic information given patient characteristics

   Author : Martin Gellerstedt; Hans Åhlfeldt; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function;

   Abstract :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. READ MORE

4. 2. Osteoporosis in women : Epidemiological and diagnostic perspectives

   Author : Owe Löfman; Dan Mellström; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : An epidemiological study of 15.462 hip fractures in Östergötland 1940-86 showed a large incidence increase mainly due to an increase in age-specific incidence of trochanteric fractures. READ MORE

5. 3. Studies on the level of substance P and calcitonin gene-related peptide in cerebrospinal fluid of pregnant women and patients with chronic pain and in rat brain after spinal cord injury : Special reference to analytical aspects of neuropeptides

   Author : Zhurong Liu; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Substance P; Calcitonin gene-related peptide; Radioimmunoassay; High performance liquidchromatography; Cerebrospinal fluid and chronic pain; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Pharmacognosy; farmakognosi;

   Abstract : Substance P (SP) and calcitonin gene-related peptide (CGRP) are sensory peptides known to be involved innociception and inflammatory processes. It is well demonstrated that the two peptides can be released from spinal cord neurons during inflammation and chronic pain induced by peripheral nerve injury. READ MORE

6. 4. Computer-­Assisted  Coronary  CT  Angiography  Analysis : From  Software  Development  to  Clinical  Application

   Author : Chunliang Wang; Örjan Smedby; Anders Persson; Hans Frimmel; Evert-jan Vonken; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vessel segmentation; coronary CTA; fuzzy connectedness; level set; coronary artery disease; Image analysis; Bildanalys; Radiological research; Radiologisk forskning;

   Abstract : Advances in coronary Computed Tomography Angiography (CTA) have resulted in a boost in the use of this new technique in recent years, creating a challenge for radiologists due to the increasing number of exams and the large amount of data for each patient. The main goal of this study was to develop a computer tool to facilitate coronary CTA analysis by combining knowledge of medicine and image processing, and to evaluate the performance in clinical settings.

7. 5. GH Secretion in children. Methodological aspects of determining immunoreactive and bioactive isoforms

   Author : Chatarina Löfqvist; Göteborgs universitet; []
   Keywords : Growth hormone; immunoassay; cross-reactivity; standard; antibody; insulin-like growth factor 1; reference values;

   Abstract : A child's hormone-dependent growth is dependent on multiple factors, although linear growth is closely associated with levels of growth hormone (GH) secretion. As GH in serum exists in several isoforms, some of which may not be identified by immunoassay, possible alterations in the secretion of these different isoforms in childhood may influence growth and/or metabolism.
