1. 1. Sex steroids and social behavior: from mouse to human

   Författare :Sara Karlsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; social memory; sociability; androgen receptor; sex steroids; genetic variations;

   Sammanfattning : Social behavior is a classification of various behaviors such as sexual behavior, aggressive behavior, social memory and sociability. These behaviors are under the regulation of the brain, and the sex steroids influence important brain regions that control these behaviors in both humans and other animals. LÄS MER

3. 2. Metabolic and ovarian consequences of perinatal sex steroid programming

   Författare :Camilla Alexanderson; Göteborgs universitet; []
   Nyckelord :programming; sex steroids; insulin resistance; skeletal muscle; adipose tissue; ovary;

   Sammanfattning : Endocrine and metabolic disturbances in adulthood may stem from insults such as nutritional and hormonal alterations that occur at critical periods in pre- or postnatal life – a process known as programming. This means that suboptimal conditions in utero and early life may contribute to adult reproductive and metabolic impairments such as type 2 diabetes, insulin resistance, and dyslipidemia. LÄS MER

4. 3. Polymorphism in sex steroid-related genes. Effects on hormone levels and behavior

   Författare :Lars Westberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex steroids; androgen receptor; estrogen receptor; progesterone receptor; polymorphism; genetics; association study; prolactin; personality; premenstrual dysphoric disorder; Parkinson s disease;

   Sammanfattning : Genetic factors are important for variations between individuals with respect to most humantraits and diseases. Sex steroids are of profound importance for reproduction, metabolism,cardiovascular function and bone formation. They are potent regulators of their ownsynthesis as well as of that of other hormones, including prolactin. LÄS MER

5. 4. New sensitive and specific methods for sex steroid measurements in rodent serum and tissues

   Författare :Maria E. Nilsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex steroids; mass spectrometry; rodents;

   Sammanfattning : Accurate measurement of sex steroids (androgens, estrogens, and progesterone) is essential in research and clinical settings for common diseases including osteoporosis, prostate cancer, breast cancer, and cardiovascular diseases. Sex steroids are not only produced in the gonads and adrenals but may also be locally synthesized in peripheral target tissues. LÄS MER

7. 5. On the influence of serotonin- and sex steroid-related genetic variation on mood, anxiety, personality, autism and transsexualism

   Författare :Susanne Henningsson; Göteborgs universitet; []
   Nyckelord :serotonin; 5-HTTLPR; TPH2; 5-HT3; sex steroids; androgen receptor; estrogen receptor; genetics; gene-gene interaction; social phobia; anxiety; premenstrual dysphoric disorder; depression; personality; autism; transsexualism; amygdala; emotional perception; life events;

   Sammanfattning : Background: The neurotransmitter serotonin has been related to mood and anxiety, and variation in genes that encode important members of the serotonergic system may hence affect mood- and anxiety-related traits. Sex steroids influence brain development, and variation in genes encoding androgen and estrogen receptors, or enzymes needed for sex steroid synthesis, may be of importance for both personality traits and risk for psychiatric disorders.
