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. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus

   Författare :Chrysoula Roufidou; Bertil Borg; Geir Lasse Taranger; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; overripening of eggs; spawning cycle; brain-pituitary-gonad BPG axis; vitellogenin; ovarian fluid; sex steroids; reproduction; three-spined stickleback; Gasterosteus aculeatus; fish; funktionell zoomorfologi; Functional Zoomorphology;

   Sammanfattning : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. LÄS MER

   Sammanfattning : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). LÄS MER

7. 5. 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
