  1. 1. Upper gastrointestinal dysmotility - from endocrinological pathogenesis to symptoms

    Författare :Julia Borg; Enheten för kroniska inflammatoriska och degenerativa sjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oxytocin; gastroparesis; functional dyspepsia; upper gastrointestinal dysmotility; CCK; gastrin; vasopressin; esophageal dysmotility; satiety; diabetes mellitus; endocrine dysregulation; gastric emptying; gastric emptying scintigraphy; gastric emptying manometry; autonomic neuropathy;

    Sammanfattning : Gastrointestinal dysmotility is common, particularly in patients with diabetes mellitus. The aim of this thesis is to explore whether gastrointestinal dysmotility and endocrine secretion are interrelated, and how the symptoms manifest themselves in these patients. LÄS MER

  2. 2. Peripheral and central factors in the pathophysiology of irritable bowel syndrome

    Nyckelord :irritable bowel syndrome IBS ; visceral perception; rectal perception; visceral hypersensitivity; gastrointestinal symptoms; hypervigilance; selective attention; stress; small intestinal bacterial overgrowth; rectal barostat; small bowel motility; gastrointestinal dysmotility;

    Sammanfattning : Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder characterized by abdominal pain and/or discomfort together with abnormal bowel habits. The pathophysiology is complex and incompletely understood. LÄS MER

  3. 3. Gastrointestinal Disorders in Women

    Författare :Rita Gustafsson; Gastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Abstract: This doctoral thesis has sought to clarify the influence of gender in gastrointestinal (GI) disorders. Women with different hormone profiles were investigated, their colonic microbiota was characterized, and the impact of lifestyle and risk factors for GI disease were examined. LÄS MER

  4. 4. Gastrointestinal motility and the role of gonadotropin-releasing hormone (GnRH)

    Författare :Oskar Hammar; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gonadotropin releasing hormone; intestinal motility; luteinizing hormone; Sjögrens syndrome; in vitro fertilization;

    Sammanfattning : This thesis explores the relation between gonadotropin-releasing hormone (GnRH) and gastrointestinal symptoms and dysmotility. In primary Sjögren’s syndrome (pSS), a patient group with high levels of GnRH antibodies, associations between objective signs and symptoms of autonomic dysfunction (AD), impaired gastric emptying (IGE), and inflammatory and serological features were studied.

  5. 5. X-ray and neutron μCT of biomedical samples: from image acquisition to quantification

    Författare :Niccoló Peruzzi; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray imaging; neutron imaging; μCT; synchrotron radiation; x-ray phase-contrast; nanoholotomography; x-ray elemental mapping; biomedical applications; virtual histology; biodegradable implants; Mg-alloys; enteric nervous system; peripheral neuropathy; gastroenteric dysmotility; Fysicumarkivet A:2021:Peruzzi;

    Sammanfattning : Even though the validity of x-ray computed tomography in the analysis of biomedical samples is nowadays undisputed, the more recent imaging techniques and more advanced instruments (such as synchrotrons) are still relatively unknown to many medical doctors that could benefit from them.The doctoral work presented in this thesis joins a collective effort from the imaging community to demonstrate potential applications of advanced x-ray and neutron imaging methods to preclinical medical research, with the hope of contributing to reach a “critical mass” in the medical community and in the public opinion as well.
