  2. 1. Pancreatic Growth and Secretion. An Experimental Study on Growth Factors in Rat and Mouse

    Author : Claes Hjalmarsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; PBD; insulin; B-cells; bile; pancreatic cancer; intestine; secretion; pancreas; proliferation; tyrphostins; CCK; epidermal growth factor; transforming growth factor alpha; cancerology; Cytologi; onkologi; cancer; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : The pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. READ MORE

  4. 2. The role of endogenous hypercholecystokininemia and hypergastrinemia in growth and carcinogenesis of the exocrine pancreas

    Author : Ming Chu; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The gut hormones cholecystokinin (CCK) and gastrin are phylogeneticallyand structurally related. Under normal conditions, CCK regulates growth of the exocrine pancreas and gastrin growth of the oxyntic mucosa of the stomach. READ MORE

  5. 3. Astrocyte-mediated short-term synaptic depression

    Author : My Andersson; Göteborgs universitet; []
    Keywords : glutamate; glia; plasticity; synapse; hippocampus;

    Abstract : Short-term synaptic plasticity, the activity-dependent regulation of synaptic efficacy that occurs in the timeframe of milliseconds to seconds, is a fundamental property of the synapse, mostly attributed to changes in release probability. These changes are commonly ascribed to intrinsic mechanisms in the presynaptic terminal and to different transmitters acting on the presynaptic terminal. READ MORE

  6. 4. Long-term effects of cholecystokinin on exocrine and endocrine pancreas

    Author : Thomas Gasslander; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The gastrointestinal hormone cholecystokinin (CCK) is known to be oneof the most potent stimulators of pancreatic growth. CCK is alsosuggested to be an initiator and/or promotor of pancreatic carcinogenesis. READ MORE

  7. 5. Programming by demonstration of robot manipulators

    Author : Alexander Skoglund; Rainer Palm; Honghai Liu; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming-by-demonstration; imitation learning; hand-state; next-state-planner; fuzzy time-modeling approach; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap; Människa-dator interaktion; Human-Computer Interaction;

    Abstract : If a non-expert wants to program a robot manipulator he needs a natural interface that does not require rigorous robot programming skills. Programming-by-demonstration (PbD) is an approach which enables the user to program a robot by simply showing the robot how to perform a desired task. READ MORE
