  2. 1. Platelets and airway remodeling : Mechanisms involved in platelet-induced fibroblast and airway smooth muscle cell proliferation in vitro

    Author : Ann-Charlotte B. Svensson Holm; Torbjörn Bengtsson; Eva Lindström; Mikael Adner; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Airway remodeling is a contributing cause to the pathological structural changes, such as increased cell proliferation, observed in asthma. Platelets have been found in autopsy lungmaterial obtained from asthmatic patients and are well known to induce proliferation in vitro of a variety of cells. READ MORE

  4. 2. Material and technique development for ultrasound optical tomography using spectral hole burning filters

    Author : Alexander Bengtsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomedical imaging; ultrasound optical tomography; acousto-optical tomography; rare-earth-ion doped crystals; spectral holeburning; slow light filters; Tm 3:LaF3; Fysicumarkivet A:2022:Bengtsson;

    Abstract : The molecular sensitivity provided by optical photons has potential advantages in medical diagnostics, for example, in distinguishing healthy from cancerous tissue. However, scattering resulting from inhomogeneities in the refractive index of tissues prevents spatially resolved optical measurements in biological material, except at very shallow depths.

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

    Author : Magnus Wilhelm Bengtsson; Gunnar Flemström; Olof Nylander; Karl E. O. Åkerman; Per M. Hellström; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
