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 [...]

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 [...]
