Effects of palatable diets on appetite regulation, appetite peptides and neurogenesis.
Obesity is increasing throughout the world at an epidemic rate, partly due to increased consumption of diets rich in fat and/or sugar. Ghrelin and leptin are hormones, originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. Circulating …

Lipid metabolism in the pancreatic beta-cell. Implications for insulin secretion.
We have investigated the role of lipid metabolism with regard to beta-cell function and insulin secretion. Lipids are known to play a crucial functional role in the pancreatic beta-cell, where they are essential for adequate hormone release, but may also exert a long-term toxic effect, leading to …

The Free Fatty Acid Receptor GPR40 - expression and role in islet hormone secretion
Type 2 diabetes (T2D) is a serious condition of growing proportions. Developing via an increasing imbalance between insulin sensitivity in the peripheral tissues and insulin release from pancreatic beta-cells, it ultimately renders the individual incapable of regulating the blood glucose …

Coupling mechanisms of insulin secretion - roles of mitochondrial metabolism and cAMP.
Type 2 diabetes is a disease that increases tremendously in the western world. It is characterized by insulin resistance and defects in insulin secretion. Insulin resistance is tightly linked to obesity, and usually precedes the onset of type 2 diabetes. When insulin resistance develops, the …

Healthy Satiety Effects of Paleolithic diet on Satiety and Risk factors for Cardiovascular disease
The prevalence of cardiovascular diseases (CVD) exhibits considerable variation across agrarian societies, whereas they are virtually absent in non-agrarian societies such as hunter-gatherer and horticultural societies. When looking for lifestyle factors which could promote CVD, it therefore seems …

Immunoregulatory differences between adult onset type 1 diabetes and latent autoimmune diabetes in adults (LADA)
Autoimmune diabetes is characterized by cell mediated autoimmunity against insulin producing beta cells in pancreatic islets. Type 1 diabetes is the major cause of diabetes in children and adolescents and is believed to be mediated by a Thl driven destruction of beta cells. The much more prevalent …

Candidate Genes for Late Diabetic Complications
Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The new WHO criteria for classification of diabetes takes into account also clinical stages dividing the diabetic patients into noninsulin …

THE ROLE OF PHOSPHODIESTERASE 3B IN CAMP-MEDIATED REGULATION OF INSULIN SECRETION
Type 2 diabetes mellitus (T2DM) is characterized by various combinations of ?-cell failure and insulin resistance leading to hyperglycemia and glucose intolerance. In order to maintain glucose tolerance in the insulin resistance state, increased insulin secretion is a requirement and it is because …

Hormonal regulation of phosphodiesterase 3B in adipocytes
Insulin induced activation of the cAMP degrading enzyme phosphodiesterase (PDE) 3B in adipocytes is important for insulin mediated inhibition of lipolysis. The aim of this thesis was to contribute with knowledge on the acute activation of PDE3B in response to insulin and catecholamines in …

Bone health and cardiovascular risk in hypopituitary patients on complete hormone replacement, including GH
Growth hormone deficiency (GHD) is associated with decreased bone mineral density (BMD). Low BMD is correlated to increased fracture risk. There are no studies on fracture risk in GHD patients on GH therapy and no studies on BMD in adults with childhood onset (CO) craniopharyngioma (CP) on GH …

Genetic and immunological risk factors of gestational diabetes mellitus
Gestational diabetes mellitus (GDM) is a heterogeneous disorder that is defined as carbohydrate intolerance with onset or first recognition during pregnancy. Impaired beta-cell function and insulin resistance are the hallmarks of GDM. The overall aim of this thesis was to study the genetic and …

Regulation of Insulin Secretion in Relation to Nitric Oxide, Carbon Monoxide and Acid alpha-Glucoside Hydrolase Activities
… this thesis the aim was to study less well-known systems involved in the complex regulation of glucose-stimulated insulin release, emphasizing the role of the lysosomal/vacuolar system and the associated glycogenolytic acid alpha-glucoside hydrolases, but also the HO-CO and NOS-NO systems. We …

Epidemiology of diabetes in a well defined population in Sweden: the Skaraborg Diabetes Registry
Time trends in prevalence, incidence and mortality was followed in 15000 diabetic patients in 1991?2005. Clinical findings, C-peptide protocols, and islet antibodies were compared in their ability to distinguish type 1 from type 2 diabetes, and factors associated with the prognosis of diabetes were …
