2. 1. The role of insulin signaling during development, reproductive diapause and aging in Drosophila Melanogaster

   Author : Sifang Liao; Dick Nässel; Heinrich Dircksen; Mark Brown; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; insulin-like peptides; reproductive diapause; behavioral senescence; neuromodulator; lifespan; funktionell zoomorfologi; Functional Zoomorphology;

   Abstract : The insulin/insulin-like growth factor signaling pathway exists from invertebrates to vertebrates and it can regulate various biological processes, including development, metabolism, stress resistance and lifespan. In Drosophila, eight insulin-like peptides (DILP1-8) have been found. READ MORE

4. 2. Polycystic ovary syndrome : Long-term health aspects

   Author : Sofia Persson; Evangelia Elenis; Inger Sundström Poromaa; Sahruh Turkmen; Elizabeth Nedstrand; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PCOS; Hyperandrogenism; Hirsutism; Fertility; Type 2 diabetes; Hypertension; Dyslipidaemia; Medicinsk vetenskap; Medical Science;

   Abstract : Polycystic ovary syndrome (PCOS) is a common endocrine disorder among women of reproductive age, affecting many aspects of women’s health such as fertility, cardiovascular health and quality of life. However, less is known about later life stages, as well as the impact of hyperandrogenism and PCOS itself, apart from risks associated with excess body weight. READ MORE

5. 3. From Birth to Senescence. Studies on factors at birth and their relation to morbidity in women in adult life

   Author : Susan W. Andersson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birth weight; birth length; gestational age; recall; epidemiology; longitudinal; middle age; women; blood pressure; hypertension; cancer;

   Abstract : This thesis is concerned with factors at birth and their relation to disease in later adulthood. The aims of this thesis were to a) identify variables in Swedish midwife records at the early part of the 1900's and their relation to birth outcome; b) assess agreement between self-reported birth weight and recorded birth weight; and, c) examine the relationship between size at birth and 1) hypertension, and, 2) cancer morbidity in adult women.

6. 4. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation

   Author : Johan Bélteky; Per Jensen; Anna Kukekova; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. READ MORE

7. 5. Strategy games; on survival and reproduction

   Author : Helen Olofsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; evolution of sexual reproduction; dormancy; game theory; migration; bet-hedging; Life history theory;

   Abstract : Classical evolutionary life history concerns questions such as optimal timing of maturation, life span and number of offspring. These questions have mostly been studied theoretically under the assumption that the environment is stable and without taking into account frequency and density dependence. READ MORE
