  1. 1. The neuropeptide VIP and the IL-6 family of cytokines in bone effects on bone resorption, cytokine expression and receptor signalling in osteoblasts and bone marrow stromal cells

    University dissertation from Umeå : Odontologi

    Author : Emma Persson; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; osteoblast; bone resorption; cytokines; IL-6; neuropeptides; VIP; transcription factor; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Abstract : Bone tissue is continuously degraded and rebuilt to respond to the needs of the body. Cells of the osteoblast lineage are responsible for the formation of bone, whereas the resorption of bone tissue is carried out by osteoclasts. READ MORE

  2. 2. The neuronal and non-neuronal substance P, VIP and cholinergic systems in the colon in ulcerative colitis

    University dissertation from Umeå : Institutionen för integrativ medicinsk biologi

    Author : Maria Jönsson; Umeå universitet.; Umeå universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ulcerative colitis; neuropeptides; substance P; VIP; non-neuronal cholinergic system; MEDICINE Morphology; cell biology; pathology Morphology Anatomy; MEDICIN Morfologi; cellbiologi; patologi Morfologi Anatomi; MEDICINE Surgery; MEDICIN Kirurgi; anatomi; Human Anatomy;

    Abstract : Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. Neuropeptides, especially vasoactive intestinal peptide (VIP) and substance P (SP), have long been considered to play key roles in UC. Among other effects, these neuropeptides have trophic and growth-modulating as well as wound-healing effects. READ MORE

  3. 3. Novel variable influence on projection (VIP) methods in OPLS, O2PLS, and OnPLS models for single- and multi-block variable selection VIPOPLS, VIPO2PLS, and MB-VIOP methods

    University dissertation from Umeå : Umeå University

    Author : Beatriz Galindo-Prieto; Umeå universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Variable influence on projection; VIP; MB-VIOP; orthogonal projections to latent structures; OPLS; O2PLS; OnPLS; variable selection; variable importance in multiblock regression; Computer Science; datalogi;

    Abstract : Multivariate and multiblock data analysis involves useful methodologies for analyzing large data sets in chemistry, biology, psychology, economics, sensory science, and industrial processes; among these methodologies, partial least squares (PLS) and orthogonal projections to latent structures (OPLS®) have become popular. Due to the increasingly computerized instrumentation, a data set can consist of thousands of input variables which contain latent information valuable for research and industrial purposes. READ MORE

  4. 4. Neuroimmune Interactions of Enteric Neurons and Mast Cells: Friends or Foes?

    University dissertation from Lund University: Faculty of Medicine

    Author : Elin Sand; Lund University.; Lunds universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enteric neurons; ischemia; VIP; mast cells; CRF;

    Abstract : Psychological distress or physical strain lead to reduced blood flow in the intestine since other organs are prioritised. One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). READ MORE

  5. 5. Intestinal barrier function in health and disease

    University dissertation from Department of Animal Physiology, Lund University

    Author : Pernilla Nejdfors; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VIP.; PACAP; secretion; ion transport; urine reservoir; radiation therapy; ulcerative colitis; macromolecules; dextran; mannitol; Ussing chamber; Intestinal permeability; mucosa; Animal physiology; Djurfysiologi; Physiology; Fysiologi;

    Abstract : The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. READ MORE
