  1. 1. Psychosocial and stress-related aspects on ischemic heart disease

    Författare :Inger M. Bengtsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Ischemic heart disease; risk factors; stress; cortisol awakening response; health related quality of life;

    Sammanfattning : Objective: To study different aspects of ischemic heart disease (IHD) i.e. stress related risk factors, biochemical markers of stress, in particular the cortisol awakening response (CAR) and outcome in terms of health related quality of life (HRQoL). Methods: 72 myocardial infarction (AMI) patients took part in the HRQoL studies. LÄS MER

  2. 2. Developmental Aspects of Drug Transport Across the Blood-Brain Barrier

    Författare :Jörgen Bengtsson; Margareta Hammarlund-Udenaes; Ann-Cathrin Engwall; Sven Björkman; Elizabeth C.M. de Lange; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; development; active transport; tight junction proteins; microdialysis; recovery; morphine; nitrofurantoin; Bcrp; microarray; real-time PCR; in vitro; in vivo; LC-MS MS; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : The developmental aspect of drug transport across the blood-brain barrier (BBB) was investigated. Microdialysis was used to study unbound morphine BBB transport at different ages in sheep. An in vitro study was performed to find differentially expressed genes in brain capillary-rich fractions of the brain in rats of different ages. LÄS MER

  3. 3. Effects of Orexins, Guanylins and Feeding on Duodenal Bicarbonate Secretion and Enterocyte Intracellular Signaling

    Författare :Magnus Wilhelm Bengtsson; Gunnar Flemström; Olof Nylander; Karl E. O. Åkerman; Per M. Hellström; Uppsala universitet; []
    Nyckelord :Physiology; alkaline secretion; carbohydrates; central nervous system; cholinergic stimulation; duodenum; enteric nervous system; enterochromaffin cell; fasting; feeding; glucose; guanylyl cyclase C; humans; hypocretin; intra-arterial; in situ; intracerebroventricular; luminal acid; luzindole; orexin-B; SB-334867; Fysiologi;

    Sammanfattning : The duodenal epithelium secretes bicarbonate ions and this is regarded as the primary defence mechanism against the acid discharged from the stomach. For an efficient protection, the duodenum must also function as a sensory organ identifying luminal factors. LÄS MER

  4. 4. β-Adrenergic Signalling Through mTOR

    Författare :Jessica M. Olsen; Tore Bengtsson; Martin Klingenspor; Stockholms universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glucose uptake; Brown adipose tissue; White adipose tissue; Skeletal muscle; Mechanistic target of rapamycin; Glucose transporter; Physiology; Physiology; fysiologi;

    Sammanfattning : Adrenergic signalling is part of the sympathetic nervous system and is activated upon stimulation by the catecholamines epinephrine and norepinephrine. This regulates heart rate, energy mobilization, digestion and helps to divert blood flow to important organs. LÄS MER

  5. 5. Image Filtering Methods for Biomedical Applications

    Författare :M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. LÄS MER
