1. 11. Acute Pancreatitis. Studies on smoking and protease activation

   Författare :Björn Lindkvist; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trypsinogen; Acute pancreatitis; trypsinogen activation peptide cathepsin B; incidence; smoking; nicotine; traumatologi; ortopedi; Kirurgi; traumatology; Surgery; orthopaedics; Gastroenterologi; Public health; epidemiology; Folkhälsa; epidemiologi; Gastro-enterology;

   Sammanfattning : Background and aims: Activation of pancreatic proteases is considered to be a crucial event in the early phase of acute pancreatitis but the cause of this activation is not known. Most cases of acute pancreatitis can be attributed to either gallstone disease or alcohol abuse. However, little is known about other risk factors. LÄS MER

3. 12. Physiological and pathophysiological regulation of ECL-cell activity

   Författare :Maria Lundgren; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy; toxicology; Pharmacological sciences; pharmacognosy; Gastroenterologi; endothelin; gastrin; ischemia-reperfusion; Physiology; Fysiologi; Gastro-enterology; pancreastatin; histamine; microdialysis; ECL-cell; stomach; Farmakologi; farmakognosi; farmaci; toxikologi;

   Sammanfattning : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin A-derived peptides in response to circulating gastrin. Mobilized histamine stimulates acid secretion from adjascent parietal cells. LÄS MER

4. 13. Early steps of Eicosanoid precursor absorption and tissue distribution

   Författare :Tor Melin; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipids; mebran; steroider; Lipider; steroids; membranes; Gastro-enterology; Gastroenterologi;

   Sammanfattning : Eicosanoids are important for a wide range of physiological and pathophysiological processes.How their essential fatty acid precursors are absorbed and tissue distributed is not well charactherized. When given orally to rats, arachidonic acid (20:4) was retained in the small intestine to a larger extent than linoleic acid (18:2). LÄS MER

5. 14. Laparoscopic or Open Antireflux Surgery - A Comparative Study with Special Reference to the Patient´s Perspective

   Författare :Gunilla Nilsson; Folke Johnsson; Bengt Hallerbäck; Institutionen för hälsovetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antireflux surgery; fundoplication; RCT; laparoscopy versus open surgery; subjective outcomes; objective outcomes; narratives; short-term follow-up; long-term follow-up; Surgery; Kirurgi; Health Informatics; Hälsoinformatik; Omvårdnad; Nursing; Gastro-enterology; Gastroenterologi; traumatology; orthopaedics; Surgery; long-term follow-up; short-term follow-up; narratives; objective outcomes; subjective outcomes; laparoscopy versus open surgery; RCT; Antireflux surgery; fundoplication; Kirurgi; traumatologi; ortopedi;

   Sammanfattning : The overall aim of this thesis was to compare the effects of laparoscopic versus open antireflux surgery in a randomized clinical trial focusing the patients' subjective and objective outcome postoperatively, from a short-term and a long-term perspective. A further aim was to describe GORD patients' experiences of illness and surgical treatment and if possible to find striking characteristics relating to laparoscopic or open surgery. LÄS MER

7. 15. Digestion and Absorption of Sphingomyelin from Milk

   Författare :Lena Nyberg; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastro-enterology; intestine; sphingolipid; ceramidase; sphingomyelinase; ceramide; Gastroenterologi;

   Sammanfattning : Sphingomyelin (SM) is a major component of mammalian cell membranes. Due to its widespread occurrence it is a dietary component, occurring mainly in milk, eggs, meat and fish. In the cell membrane SM was earlier considered to be only a structural element, which interacts with cholesterol and forms a system for bilayer stabilization. LÄS MER
