2. 1. PET imaging of beta-cell mass

   Author : Pierre Cheung; Olof Eriksson; Weibo Cai; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; diabetes; beta-cell mass; affibody; SC-islets; Medicinal Chemistry; Läkemedelskemi;

   Abstract : A hallmark of diabetes is the progressive loss of the beta-cell mass (BCM) and function. Most of the diagnostic methods for diabetes are mostly reflective of the beta-cell function, whereas current methodologies for studying the beta-cell mass are limited to post-mortem biopsies or highly invasive methods.

4. 2. Imaging Islets of Langerhans by Positron Emission Tomography : Quantification of Beta-Cell Mass in the Native Pancreas and the Islet Graft

   Author : Olof Eriksson; Anders Sundin; Olle Korsgren; Bengt Långström; Bo Nilsson; Håkan Ahlström; Habib Zaidi; Uppsala universitet; []
   Keywords : Positron Emission Tomography; [18F]FDG; dihydrotetrabenazine; Islet transplantation; IBMIR; beta-cell mass; MEDICINE; MEDICIN;

   Abstract : Type 1 and 2 Diabetes Mellitus are a growing health problem throughout the world. There is an increasing  need for methodologies, which are both reliable and non-invasive to measure the amount of insulin-producing tissue (Beta-cell mass, or BCM), as well as rapidly quantify changes in the BCM due to the onset of disease, beta-cell replacement therapy, or other treatments.

5. 3. TGFβ and LXR signaling in hepatocellular carcinoma

   Author : Claudia Bellomo; Aristidis Moustakas; Lars Holmgren; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hepatocellular Carcinoma; high-throughput imaging; small molecules; epithelial plasticity; LXR; Snail; TGFβ; tumor suppression; reactive oxygen species; cancer-associated fibroblast; myofibroblast; Smad3; αSMA;

   Abstract : Hepatocellular carcinoma (HCC) is one of the most prevalent cancer types in the Western world and in the Asia-pacific regions, with its incidence expected to rise up to 22 million cases till 2020. Hepatocellular carcinoma etiology is mainly due to hepatitis B (HBV) and hepatitis C (HCV) infections, and to a lesser extent it is determined by the development of alcohol-driven cirrhosis and non-alcoholic steatohepatitis (NASH).

6. 4. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity

   Author : Marie Andersson; Ingvar Brandt; Cynthia de Wit; Uppsala universitet; []

   Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

7. 5. [68Ga]Exendin-4: Bench-to-Bedside : PET molecular imaging of the GLP-1 receptor for diabetes and cancer

   Author : Ram kumar Selvaraju; Olof Eriksson; Olle Korsgren; Lars Johansson; Martin Gotthardt; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; [68Ga]Exendin-4; beta cell imaging; insulinoma; dosimetry;

   Abstract : Diabetes epidemic is underway. Beta cell dysfunction (BCF) and loss of beta cell mass (BCM) are known to be key events in its progression. Currently, there are no reliable techniques to estimate or follow the loss of BCM, in vivo. READ MORE
