Identifiable Prediction Animal Model for the Bi-Hormonal Intraperitoneal Artificial Pancreas
Davari Benam, Karim; Khoshamadi, Hasti; Åm, Marte Kierulf; Stavdahl, Øyvind; Gros, Sebastien; Fougner, Anders Lyngvi (Peer reviewed; Journal article, 2022)To achieve a fully automatic artificial pancreas (AP), i.e., an AP without the need for meal announcements, the intraperitoneal (IP) route is explored. This route has faster dynamics than the typical subcutaneous (SC) ... -
Impact of sensing and infusion site dependent dynamics on insulin bolus based meal compensation
Kölle, Konstanze; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2017)Meals are most challenging in the regulation of blood glucose levels (BGL) in diabetes mellitus type 1, whether it is automated, semi-automated or manually controlled. The common subcutaneous (SC) route for glucose sensing ... -
Improved Precision-Estimation of Virtual Patient Models
Bugge, Mai Ve (Master thesis, 2021)Diabetes er en kronisk sykdom som påvirker kroppens evne til å regulere blodsukkeret til et anstendig og bærekraftig nivå. Behandling av diabetes, spesielt av type I diabetes, inkluderer insulinbehandling for å minimere ... -
Intraperitoneal and subcutaneous glucagon delivery in anaesthetized pigs: effects on circulating glucagon and glucose levels
Åm, Marte Kierulf; Dirnena-Fusini, Ilze; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2020)Glucagon is a pancreatic hormone and increases the blood glucose levels. It may be incorporated in a dual hormone artificial pancreas, a device to automatically and continuously control blood glucose levels of individuals ... -
The intraperitoneal artificial pancreas: glucose sensing and glucagon delivery
Åm, Marte Kierulf (Doctoral theses at NTNU;2020:267, Doctoral thesis, 2020)Norsk sammendrag Diabetes er en gruppe sykdommer som globalt rammer millioner av mennesker. Denne avhandlingen fokuserer på diabetes mellitus type 1 som kjennetegnes av ingen, eller veldig liten, produksjon av insulin. ... -
Intraperitoneal insulin administration - superior choice for an artificial pancreas?
Dirnena-Fusini, Ilze (Doctoral theses at NTNU;2021:334, Doctoral thesis, 2021)The main focus of this thesis is to explore the intraperitoneal (IP) cavity as the location for insulin administration. We hypothesized that IP insulin administration is more physiologic as it mimics endogenous insulin ... -
