1. Skeletal muscle fiber types in man : With special reference to anabolic signaling and mitochondrial bioenergetics
Sammanfattning : Human skeletal muscle consists of a mixture of slow-twitch (type I) and fast-twitch (type II) fibers. The type I fibers are endurance-oriented, with a metabolic system and infrastructure that supports aerobic metabolism. LÄS MER
2. Characterization of Impaired Glucose Tolerance - Insulin Sensitivity, Islet Function and Metabolic Risk Factors
Sammanfattning : This thesis presents a three-year prospective study on metabolic characteristics of impaired glucose tolerance (IGT) and the regulation of insulin sensitivity versus islet function in relation to changes in glucose tolerance. 108 non-diabetic women aged 57-58 years were randomly selected from a population of women born in 1935 with a high prevalence of IGT.

3. Insulin signal transduction in skeletal muscle : special consideration for insulin resistance and diabetes
Sammanfattning : This dissertation work is focused on the insulin-signal-transduction pathways to glucose transport in skeletal muscle from animal models of NIDDM. The overall objective is to determine the effectiveness of different pharmacological treatments to improve insulin action in skeletal muscle. LÄS MER
4. Exercise effects on the mitogen-activated protein (MAP) kinase cascade in skeletal muscle
Sammanfattning : Exercise-induced adaptations in skeletal muscle are regulated by numerous signaling mechanisms. However, little is known about the molecular signaling mechanisms linking muscle contraction or other exercise-associated stimuli to intracellular responses in skeletal muscle. LÄS MER
5. Effect of hyperglycemia on glucose transport and intracellular signal transduction in skeletal muscle
Sammanfattning : Recent studies revealing the components of insulin signal transduction have raised the question of whether the defects in insulin signaling account for disturbed glucose metabolism in people with NIDDM. The major focus of this thesis is to elucidate the role of insulin signal transduction in the development of peripheral insulin resistance. LÄS MER
