Genetic Susceptibility, Lifestyle, Ovarian Hormones, and Mammographic Density – key factors in breast cancer development. The Norwegian Energy Balance and Breast Cancer Aspects-I Study.
(Doctoral thesis; Doktorgradsavhandling, 2013-02-28)Breast cancer is the most frequent cancer among women worldwide. Over the last century, the prevalence of overnutrition, overweight and obesity has increased, age at menarche has dropped and age at birth of first child has risen among women in Western countries. These trends may be linked to exposure to ovarian hormones that, in turn, may affect a woman’s lifetime risk of getting breast cancer. The ... -

A genome-wide study of gene expression regulation in the Gram-negative fish pathogen Aliivibrio salmonicida
(Doctoral thesis; Doktorgradsavhandling, 2011-10-04)Regulation of gene expression is essential for all bacteria to function and survive. The expression of genes into proteins is dependent on a number of steps, each of which can be subjected to regulation. In the literature much emphasis has typically been placed on transcriptional regulation, but during recent years gene regulation at the post-transcriptional level has also gained much attention. One ... -

Guanylate cyclase activators and stimulators. Potential cardiovascular therapeutics, with special focus on the right ventricle
(Doctoral thesis; Doktorgradsavhandling, 2022-09-09)<p><i>Background -</i> Soluble guanylate cyclase, sGC, is a major contributor to the signal transduction in the cardiovascular system, and dysfunction in the NO-sGC-cGMP signaling plays an important role in cardiovascular disease. This system is sensitive to a wide variety of pathological conditions spanning from substrate shortage to sGC-insensitivity to nitric oxide (NO), during pathological ... -
Harnessing Innate Immunity - Complement and TLR Inhibition in Experimental Models of Gram Positive and Polymicrobial Bacteremia and Sepsis
(Doctoral thesis; Doktorgradsavhandling, 2017-11-28)Sepsis is a syndrome of life-threatening organ malfunction caused by a dysregulated host response to infection. The complement, kallikrein/kinin, coagulation and fibrinolysis plasma cascade systems as well as the TLR system recognize and initiate the immediate responses to infection and thus play an important role in the development of sepsis. In this regard, the ubiquitous TLR co-receptor, CD14, ... -
