   Abstract : 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). READ MORE

4. 2. Effects of neuroactive steroids on the recombinant GABAA receptor in Xenopus oocyte

   Author : Mozibur Rahman; Ming-De Wang; Bjarke Ebert; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; GABA; GABAA receptor; neuroactive steroids; Obstetrics and gynaecology; Obstetrik och gynekologi;

   Abstract : Introduction: Neuroactive steroids represent a class of both synthetic and naturally occurring steroids that have an effect on neural function. In addition to classical genomic mechanism by the hormones progesterone, deoxycorticosterone and testosterone 3α-OH metabolites of these hormones enhance GABAA receptor through rapid non-genomic mechanism.

5. 3. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS

   Author : Jessica Strömberg; Per Lundgren; Torbjörn Bäckström; David Haage; Esa Korpi; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; allopregnanolone; chloride ion uptake; patch-clamp; 3beta-steroids; kinetic parameters; rat brain; Obstetrics and gynaecology; Obstetrik och gynekologi;

   Abstract : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. READ MORE

6. 4. Hormones, Mood and Cognition

   Author : Kristiina Kask; Inger Sundström Poromaa; Torbjörn Bäckström; Britth-Marie Landgren; Uppsala universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; startle response; prepulse inhibition; premenstrual dysphoric disorder; menstrual cycle; pregnancy; postpartum period; episodic memory; semantic memory; working memory; progesterone; estradiol; allopregnanolone.; Obstetrics and gynaecology; Obstetrik och gynekologi;

   Abstract : Ovarian steroid hormones are neuroactive steroids with widespread actions in the brain, and are thus able to influence mood, behavior and cognition. In this thesis the effects of progesterone withdrawal and the direct effects of the progesterone metabolite allopregnanolone are evaluated. READ MORE

7. 5. Healthy women or risk patients? : Non-attendance in a cervical cancer screening program

   Author : Marie Oscarsson; Eva Benzein; Barbro Wijma; Eva Johansson; Linköpings universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Non-attendance; screening; cervical cancer; health promotion; improverment; informed consent; Obstetrics and gynaecology; Obstetrik och gynekologi; Omvårdnad;

   Abstract : Women afflicted with cervical cancer who have the highest morbidity and mortality rates have been the least likely to be screened. The overall aim of this research project was to investigate non-attendance in a cervical cancer screening (CCS) program among women with no registered cervical smear during the previous five years.
