2. 1. Small Intestinal Neuroendocrine Tumor : A Rare Malignancy with Favorable Outcome

   Author : Olov Norlén; Peter Stålberg; Per Hellman; Peyman Björklund; Anders Sundin; Peter Naredi; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroendocrine tumor; peritoneal carcinomatosis; single nucleotide polymorphism array; liver metastases; radiofrequency ablation; liver surgery; positron emission tomography; somatostatin analogs; cholecystectomy; Kirurgi; Surgery;

   Abstract : Small intestinal neuroendocrine tumor (SI-NET) is the most common small bowel tumor in Europe and USA, with an annual incidence of around 0.3-1.3/100000 persons. READ MORE

4. 2. Small Intestinal Neuroendocrine Tumor Analyses : Somatostatin Analog Effects and MicroRNA Profiling

   Author : Su-Chen Li; Valeria Giandomenico; Kjell Öberg; Marco Volante; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Small intestinal neuroendocrine tumors; Somatostatin analogs; Laser-capture microdissection; Microarray profiling and microRNA profiling; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Abstract : Small intestinal neuroendocrine tumors (SI-NETs) originate from serotonin-producing enterochromaffin (EC) cells in the intestinal mucosa. Somatostatin analogs (SSAs) are mainly used to control hormonal secretion and tumor growth. However, the molecular mechanisms leading to the control of SI-NETs are unknown. READ MORE

5. 3. Natural killer T (NKT) lymphocytes regulate of intestinal tumor immunity

   Author : Ying Wang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NKT lymphocyte; intestinal tumor; CD1d; colrectal cancer; immunoregulation; α-gagactosylceramide;

   Abstract : CD1d-restricted natural killer T (NKT) lymphocytes are known as potent early regulatory cells of immune responses, acting as a bridge between innate and adaptive immunity. While invariant NKT (iNKT) cells have a protective role in many tumor models, their ability to promote intestinal inflammation, known to enhance intestinal cancer, raised the question if they would be protective in intestinal tumor development.

6. 4. Human intestinal alkaline phosphatase : tissue expression and serum levels

   Author : Ulla Domar; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human alkaline phosphatase; intestinal alkaline phosphatase; blood; blood group; lipid; monoclonal antibody; immunohistochemistry; liver; kidney; pancreas; liver disease; inflammatory bowel disease;

   Abstract : Human alkaline phosphatase (ALP) comprises four isozymes, viz liver/bone/ kidney or tissue unspecific (AP), intestinal (LAP), placental (PLAP) and germ cell or PLAP-like alkaline phosphatase, with their main expression in specific tissues as indicated by their names. The isozymes are coded by different genes, but they are closely related, with more than 50% amino acid sequence homologies. READ MORE

7. 5. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

   Author : Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

   Abstract : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. READ MORE
