1. 21. Clinical and etiological studies on dementia of Alzheimer type and multiinfarct dementia

   Författare :Gösta Bucht; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dementia of Alzheimer type; multiinfarct dementia; clinical studies; diagnosis; blood cerebrospinal fluid barrier function; cytogenetic changes; blood glucose; insulin secretion;

   Sammanfattning : 1. Clinical studies. Clinical diagnosis of dementia has been made largely on the basis of clinical findings supported by appropriate radiological and laboratory investigations. A minority of patients have treatable or reversible underlying causes for their dementing syndrome. LÄS MER

3. 22. Quantitative assessment of myocardial infarction: On the relationship between anatomy and electrophysiology using MRI and ECG

   Författare :Henrik Engblom; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; magnetic resonance imaging; tomography; medical instrumentation; Clinical physics; radiology; electrocardiography; myocardial infarction; ischemic heart disease; Cardiovascular system; Diagnostics; Diagnostik; Kardiovaskulära systemet;

   Sammanfattning : Both presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. LÄS MER

4. 23. Variability of blood pressure and heart rate in borderline and mild hypertension : With special reference to spectral analysis

   Författare :Reijo Takalo; Uppsala universitet; []
   Nyckelord :Medical sciences; hypertension; blood pressure; ambulatory monitoring; power spectrum analysis; pulsecontour method; systemic hemodynamics; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : The aim of this thesis was to study whether blood pressure (BP) or heart rate (HR) variability in borderline (BHT) and hypertensive (HT) subjects differs from that in normotensive (NT) subjects, and whether indices for BP and HR variability can be used in risk stratification for future hypertension. The study groups consisted of 35 NT, 29 BHT, and 34 HT middle-aged men. LÄS MER

5. 24. Life Cycle Assessment of Paper Based Printed Circuits

   Författare :Qiansu Wan; Li-Rong Zheng; Changqing Liu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Printed Electronics; Environment; PCB; Life Cycle assessment; Emissions; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.

7. 25. On vascular endothelial growth factor B and platelet-derived growth factor C : two members of the VEGF/PDGF family of growth factors

   Författare :Karin Aase; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Vascular endothelial growth factors (VEGFs), platelet-derived growth factors (PDGFs) and their receptors are important for normal development. They have also been implicated in many pathological conditions. VEGFs have been shown to play an important role in the development of both blood and lymphatic vessels. LÄS MER
