1. 1. Temporary neonatal exposure to whole and hydrolysed cow's milk proteins. Studies of macromolecular absorption and immunological variables

   Författare :Pekka O Juvonen; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; beta-lactoglobulin; ovalbumin; cow s milk proteins; antibodies; IgG; IgE; secretory IgA; alpha-lactalbumin; breast-feeding; Pediatrics; Pediatri; early infant feeding; casein hydrolysate; Human milk; cow s milk;

   Sammanfattning : The aim of this work was to study prospectively the effects of different feeding regimens during the first three days of life. A group of 129 infants were randomly assigned at birth to one of three feeding regimens: human milk (HM), cow's milk formula (CMF), or a casein hydrolysate formula (CHF). LÄS MER

3. 2. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

   Författare :Anna Karin Morén; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. LÄS MER

4. 3. Epithelial barrier dysfunction in ileal Crohn's disease

   Författare :Johan Dabrosin-Söderholm; Svante Nordgren; Linköpings universitet; []

   Sammanfattning : The study aimed at investigating the intestinal barrier in Crohn's disease, with special reference to epithelial responses to luminal stimuli, and to permeation of proteins.Ileal mucosa from patients undergoing intestinal resection was studied in vitro in Ussing chambers.

5. 4. An experimental study of mediators in allergic bronchoconstriction with focus on eicosanoids

   Författare :Ewa Selg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Leukotrienes; prostaglandins; histamine; guinea pig lung; ovalbumin; mast cell; cyclooxygenase; airway smooth muscle; COX inhibitors; NSAIDs;

   Sammanfattning : Mast cells have a central role in the inflammatory response in airways of both atopic and non-atopic asthmatics. The mast cell-derived mediators such as histamine, leukotriene C4 and prostaglandin D2, released upon activation of the cell, produce acute bronchoconstriction that is characteristic of the early asthmatic response (EAR), and contribute to the development of airway inflammation and hyperresponsiveness following the initial reaction.

7. 5. Nitric oxide and eicosanoids : significance and interactions during antigen-induced responses in peripheral lung tissue

   Författare :Anna-Karin Larsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Nitric oxide; leukotrienes; prostaglandins; histamine; ovalbumin; contractions; distal lung; rat; human; guinea pig; precision-cut lung slices; mast cell;

   Sammanfattning : Asthma means difficulty in breathing and is described as a chronic, inflammatory disorder that produces narrowing of the lower respiratory tract. The allergen-induced asthmatic bronchoconstriction is primarily caused by an IgE-mediated release of the mast cell mediators, histamine and eicosanoids (leukotrienes and prostanoids). LÄS MER
