    Författare :Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

    Sammanfattning : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. LÄS MER

  3. 2. Premenstrual dysphoric disorder in relation to neuroactive steroids and alcohol

    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

    Sammanfattning : Thyroid associated ophthalmopathy (TAO) is the orbital manifestation of autoimmune thyroid disease that clinically affects about 30-50 % of patients with Graves disease (GD). The clinical features of TAO are in most patients mild and transient. LÄS MER

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

    Författare :Anna-Carin Wihlbäck; Tord Naessén; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Allopregnanolone effects in women : clinical studies in relation to the menstrual cycle, premenstrual dysphoric disorder and oral contraceptive use

    Författare :Erika Timby; Marie Bixo; Torbjörn Bäckström; Anna-Carin N Wihlbäck; C Neill Epperson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; GABAA receptor; menstrual cycle; premenstrual dysphoric disorder; saccadic eye velocity; oral contraceptives; hypothalamic amenorrhea;

    Sammanfattning : Background: Premenstrual dysphoric disorder (PMDD) affects 3–8% of women in fertile ages. Combined oral contraceptives (OCs) are widely used and some users experience adverse mood effects. The cyclicity of PMDD symptoms coincides with increased endogenous levels of allopregnanolone after ovulation. LÄS MER
