   Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

3. 7. Stroke, Sex and Vascular Receptor Changes in the Brain

   Sammanfattning : Stroke is a severe cerebrovascular disease in which the neuronal tissue and vasculature of the brain undergo ischemia-evoked alterations. We have demonstrated an increased expression of cerebrovascular contractile receptors in the brain. This is hypothesized to mitigate cerebral blood flow and exacerbate tissue damage after stroke.

   Sammanfattning : There are today only a few population-based studies in the world investigating the prevalence of and associated risk-factors with adolescents selling sex and so far no earlier population-based study has been found investigating adolescents motives for selling sex. Further, to use sex in means of self-injury (SASI) is a behaviour that has been highlighted in Sweden the last years but it is a new field of research and a behaviour in need of conceptualization.

Central to the study is the analysis of the tensions between a public discourse favoring openness for lesbians, gays, and bisexuals and a lack of acknowledgment of non-heterosexual family practices; as well as the tensions between gender equality policies and discourses and the specific construction of same sex couples.
