  1. 1. Optical projection tomography based 3D-spatial and quantitative assessments of the diabetic pancreas

    University dissertation from Umeå : Umeå centrum för molekylär medicin (UCMM)

    Author : Tomas Alanentalo; Ulf Ahlgren; Raphael Scharfmann; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nkx; development; optical projection tomography; 3D visualisation; pancreas; beta-cell mass; insulitis; diabetes; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Abstract : The gastrointestinal tract comprises a number of digestive organs including the stomach and pancreas. The stomach is involved in the digestion and short term storage of food while the pancreas is a mixed endocrine and exocrine gland which provides the body with hormones and enzymes essential for nutritional utilisation.

  2. 2. The Colours of Diabetes advances and novel applications of molecular optical techniques for studies of the pancreas

    University dissertation from Umeå : Umeå universitet

    Author : Christoffer Nord; Ulf Ahlgren; Ian Smyth; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optical projection tomography; Technique development; Near-infrared; 3D visualization; Biomedical imaging; ß-cell mass; Diabetes; Vibrational micro spectroscopy;

    Abstract : Diabetes is a rapidly increasing health problem. In a global perspective,approximately 415 million people suffered from diabetes in 2015 and this number ispredicted to increase to 640 million by 2040. To tackle this pandemic there is a needfor better analytical tools by which we can increase our understanding of the disease. READ MORE

    Abstract : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. READ MORE

  4. 4. Spindle vibration and sound field measurement using optical vibrometry

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kourosh Tatar; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Mechanical systems often produce a considerable amount of vibration and noise. To be able to obtain a complete picture of the dynamic behaviour of these systems, vibration and sound measurements are of significant importance. Optical metrology is well-suited for non-intrusive measurements on complex objects. READ MORE

  5. 5. Spleno-pancreatic development assessed by 3D molecular imaging

    University dissertation from Umeå : Umeå centrum för molekylär medicin (UCMM)

    Author : Amir Asayesh; Ulf Ahlgren; Beatriz Sosa-Pineda; [2007]
    Keywords : Cell biology; Spleen; Pancreas; Imaging; Development; Cellbiologi; miljömedicinsk utvecklingsbiologi; Developmental Biology;

    Abstract : The development of different organs and tissues along the gastrointestinal tract, including the pancreas, depends on signalling between the endoderm and the adjacent mesenchyme. The Nkx gene Bapx1 is involved in spatial control of organ-positioning in the spleno-pancreatic region, and deficiency in this gene results in unacceptable proximity of the splenic mesenchyme to the pancreas.
