16. RAS-MAPK syndromes - a Clinical and Molecular Investigation
Sammanfattning : The RAS-MAPK syndromes are a group of clinically and genetically related disorders, characterized by cardiac defects, facial dysmorphism, cutaneous abnormalities and neurocognitive impairment. The pathogenesis is dysregulation of the RAS-MAPK pathway, and several genes within the pathway are involved. LÄS MER
17. Human glycogen synthase genes. Role in insulin resistance and hypoglycaemia
Sammanfattning : Effective insulin-stimulated storage of excess glucose after a meal, and its rapid mobilisation in the fasting state provide basis of glucose homeostasis. Glycogen is the macromolecular storage form of glucose and glycogen synthase (GS) is the rate-limiting enzyme in glycogen synthesis. Skeletal muscle and liver are the major depots of glycogen.

18. Mutations and Mutation Rate in the Development of Fluoroquinolone Resistance
Sammanfattning : The emergence of multidrug resistant bacteria world wide is a serious problem, and very few new drugs are under development. The selection of resistant bacteria is affected by factors such as mutation rate, biological fitness cost and the rate of fitness compensation. LÄS MER
19. Wnt/β-Catenin Signalling in Parathyroid Tumours
Sammanfattning : Primary hyperparathyroidism (pHPT) due to parathyroid tumours with hypersecretion of parathyroid hormone and hypercalcaemia is a common disease with incompletely understood etiology affecting more than 1 % of the population, primarily postmenopausal women. In secondary hyperparathyroidism (sHPT), parathyroid tumours develop in response to calcium and vitamin D deficiency generally in patients with uraemia. LÄS MER
20. Genetic variability of hepatitis B virus in chronic infection
Sammanfattning : Chronic hepatitis B is a major health problem, and may lead to cirrhosis and hepatocellular carcinoma. The liver damage in hepatitis B virus (HBV) infection is considered to be a result of the immune response, and not a cytopathic effect of the virus itself. LÄS MER
