1. 36. 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

3. 37. 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

4. 38. 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

5. 39. Premenstrual dysphoric disorder in relation to neuroactive steroids and alcohol

   Författare :Sigrid Nyberg; Britth-Marie Landgren; Umeå universitet; []
   Nyckelord :premenstrual dysphoric disorder; GnRH-agonist; progesterone; allopregnanolone; alcohol; saccadic eye velocity; obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : Introduction: Premenstrual Dysphoric Disorder (PMDD) is a condition that affects about 2-6% of women of reproductive age. The relation to ovarian steroids is apparent as symptoms are absent during anovulatory cycles. LÄS MER

7. 40. Nitric oxide synthase in female reproductive and urinary organs: Hormonal regulation and functional significance

   Författare :Jassim Al-Hijji; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; estrogen; trophoblast; placenta; vagina; Nitric oxide; uterus; ovarian steroids; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

   Sammanfattning : Nitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. LÄS MER
