Elmar Tobi | 29-10-2013 | Epigenetic differences after prenatal adversity: The Dutch Hunger Winter This thesis is a study on the link between early development and adult health. Studies in animal models indicate that so-called epigenetic marks may be influenced by nutrition during development, changing the expression of genes implicated in disease. Epigenetics may [...]
Maarten Rozing| 21-09-2011 | Endocrine and metabolic features of familial longevity The Leiden Longevity Study This thesis discusses the metabolic and endocrine characteristics of long-lived Dutch families. We found that familial longevity is marked by low thyroid function and preserved insulin senitivity. The second part of this thesis adresses the Gompertz law of mortality [...]
Rita Slof-Op 't Landt| 04-12-2007 | Genetic determinants of eating disorders In this thesis, a series of studies on different aspects of the genetics of eating disorders is presented. The heritability of disordered eating behavior and attitudes in relation with body mass index (BMI) was evaluated in a large adolescent twin-family sample ascertained through [...]
Renée Ruhaak | 24-03-2011 | Glycomics based biomarkers of the rate of aging: Development and applications of high throughput N-glycan analysis Markers for longevity, which reflect the health condition and predict healthspan are extremely scarce. Such markers are, however, valuable in aging research. Protein N-glycosylation is an important post-translational modification, which has been shown [...]
Steffan Bos | 15-09-2010 | Genes and Mediators of Inflammation and Development in Osteoarthritis Osteoarthritis (OA) mainly affects the articular cartilage covering the bones. In this thesis we investigated the relation between levels of inflammatory mediators, genes involved in their regulation and the disease status of OA. We investigated the role of genetic variation [...]
Simon Mooijaart| 04-12-2007 | Genetic Determinants of Healthy Longevity Lifespan in under genetic control. In this thesis we translated genes regulating lifespan in model organisms to humans. First we identified DAF-12 as a critical gene for lifespan regulation in the nematode worm C. elegans. Then we found that the Liver X Receptors and the [...]
Maris Kuningas | 04-12-2007 |A Study into Genes Encoding Longevity in Humans The lifespan of an organism is determined by a complex network of environmental-, genetic- and stochastic factors. Each of these components contributes to the wide variability in lifespan between and within species. In recent years, it has been shown that 20-30 % of [...]
Josine Min | 17-01-2007| Generalised Osteoarthritis: from Mendelian Disorder to Complex Disease Osteoarthritis (OA) is a prevalent and complex disorder with a high hereditary probability. Previous genetic research into OA has yielded several common gene variants contributing to joint specific OA phenotypes. Only a few studies allowed an examination of multiple joint sites in the [...]
Naghmeh Riyazi | 22-11-2006 | Familial osteorarthritis : risk factors and determinants of outcome Osteoarthritis (OA) refers to a heterogeneous group of conditions. This thesis focuses on OA with a hereditary background; Familial OA at multiple joint sites and radiological hand OA at middle age. The main objective is to identify risk factors that [...]
B.Z. Alizadeh (Behrooz)| 23-03-2005 | Osteoarthritis and hemochromatosis, a genetic epidemiological study Osteoarthritis (OA) refers to a heterogeneous group of distinct diseases which express a common radiographic and clinical phenotype at diarthrodial joints.It is the leading cause of pain and disability in the elderly with a prevalence of 75 percent in the population [...]
