1. 21. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

   Författare :Anna Webb; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.

3. 22. Epidemiological and experimental studies on sarcoma with focus on gastrointestinal stromal tumors

   Författare :Fredrik Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Sarcoma is the common denominator for malignant tumors of mesenchymal origin. Sarcomas encompass almost 100 diagnoses with different histology, molecular features and natural history, and may present in any part of the body. The most common sarcoma in the abdomen is the gastrointestinal stromal tumor (GIST). LÄS MER

4. 23. Probiotics and berry-associated polyphenols: catabolism and antioxidative effects

   Författare :Maja Jakesevic; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bilberry; Rosehips; Chokeberry; Probiotics; Lactic acid bacteria; Polyphenols; Ischemia-reperfusion; Oxidative stress;

   Sammanfattning : Oxidative stress can cause damage to DNA, proteins and lipids and is associated with inflammation and various human diseases as cancer, atherosclerosis, and autoimmune diseases. Polyphenol-rich diet, such as fruits and berries, may act as antioxidants and prevent oxidative stress and, thereby, associated diseases. LÄS MER

5. 24. Intestinal barrier function in health and disease

   Författare :Pernilla Nejdfors; Biologiska institutionen; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 25. Mapping Transcriptomes in Tissues

   Författare :Ludvig Larsson; Joakim Lundeberg; Stefania Giacomello; Naveed Ishaque; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spatially resolved transcriptomics; spatial transcriptomics; transcriptomics; data analysis; rumsligt upplöst transkriptomik; rumslig transkriptomik; transkriptomik; dataanalys; Biotechnology; Bioteknologi;

   Sammanfattning : Over the past few decades, the advent of pioneering biotechnological methods has allowed scientists to analyze the molecular components of multicellular organisms with remarkable precision. The field of transcriptomics has witnessed a rapid development of technologies for gene expression profiling of biological samples. LÄS MER
