2. 6. Stroke, Sex and Vascular Receptor Changes in the Brain

   Author : Hilda Ahnstedt; Lund Medicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endothelin receptors; Cerebral ischemia; sex; estrogen; progesterone; sex differences; human cerebral arteries; endothelin-1; angiotensin II; middle cerebral artery occlusion; extra-cellular signal regulated kinase 1 and 2;

   Abstract : 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.

4. 7. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction

   Author : Emmanouil Tsakoumis; Monika Schmitz; Tatjana Haitina; Åsa Wallén-Mackenzie; Ana Gómez Peris; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zebrafish; leptin; appetite; GRN; brain; reproduction; oocyte maturation; ovulation; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

   Abstract : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. READ MORE

5. 8. Ovarian hormones and effects in the brain : studies of neurosteroid sensitivity, serotonin transporter and serotonin2A receptor binding in reproductive and postmenopausal women

   Author : Anna-Carin Wihlbäck; Tord Naessén; Umeå universitet; []
   Keywords : estradiol; progesterone; progestin; neurosteroids; saccadic eye velocity; sedation; hormone replacement therapy HRT ; menopause; menstrual cycle; mood; serotonin; paroxetine; lysergic acid diethylamide; platelets; obstetrik och gynekologi; Obstetrics and Gynaecology;

   Abstract : Background: Estrogen has been reported to enhance well-being and quality of life during the climacteric phase. In women with an intact uterus estrogen treatment is always combined with progestins in order to protect the endometrium from hyperplasia and malignancies. READ MORE

6. 9. Galanin and NPY in the rodent brain: rapid effects of 17beta-estradiol and possible roles in hippocampal plasticity

   Author : Susanne Hilke; Elvar Theodorsson; Tomas Hökfelt; Bruce S. McEwen; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sex-hormones; Brain; Neuropeptides; Neurochemistry; Neurokemi;

   Abstract : The neuropeptides galanin and neuropeptide Y (NPY) play an important role in the reproduction of rodents, e.g. by modulating the release of gonadal hormones, the nutritional status by effects on feeding behavior and also by influencing mating behavior. READ MORE

7. 10. Estrogen-inducible neuropeptides in the rat brain: role in focal ischemic lesions

   Author : Annette Theodorsson; Elvar Theodorsson; A: Langmoen; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Estrogen; neuropeptides; galanin; cerebral ischemia; middle cerebral artery occlusion; Neurochemistry; Neurokemi;

   Abstract : Sex steroids in general and estrogens in particular – in addition to their effects on the reproductive organs – affect a large number of crucial bodily functions, including “higher” brain functions.Neuropeptides constitute the phylogenetically oldest neurotransmitter system and are currently thought to act mainly during stress, disease or injury.
