  2. 6. Sex steroids, IGF-I, and vascular morphology from birth to adulthood in individuals born small for gestational age

    Author : Kerstin Allvin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small for gestational age; preterm; sex steroid; estradiol; testosterone; dihydrotestosterone; glucocorticoid; retina; IGF-I;

    Abstract : Abstract Aim: To study whether there is an association between size at birth, sex steroids, IGF-I, and retinal vascular morphology. Patients and methods: Two different cohorts were studied. In paper I, 25 young adult men born small for gestational age (SGA) were compared to 44 young adult men born appropriate for gestational age (AGA). READ MORE

  4. 7. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

    Author : David Gunnarsson; Gunnar Selstam; Gunnar Nordberg; Per Leffler; Henrik Leffers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; Molecular biology; Molekylärbiologi;

    Abstract : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. READ MORE

  5. 8. Actions of androgens and estrogens in experimental models of cardiovascular disease

    Author : Johan Bourghardt Fagman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AR; atherosclerosis; AAA; androgens; testosterone; 2-methoxyestradiol;

    Abstract : Men are at higher risk of developing both atherosclerotic cardiovascular disease and abdominal aortic aneurysm (AAA). Actions of sex steroids are hypothesized to underlie these gender differences. Testosterone, the major androgen, reduces atherosclerosis in male animal models but is suggested to promote AAA formation. READ MORE

  6. 9. Serotonergic and steroidal influences on impulsive behaviour in rats

    Author : John L. Evenden; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; impulsivity; serotonin; 8-OH-DPAT; DOI; steroid; testosterone; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : Impulsiveness is a trait contributing to the personality of all human beings to a greater and lesser extent. In a pathological form it can lead to impulsive behaviour which is an important component of many psychiatric and neurological disorders. READ MORE

  7. 10. Psychopathy and biological markers in a forensic psychiatric population

    Author : E. Gunilla Stålenheim; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psychiatry; Psychopathy; DSM-III-R; DSM-IV; KSP; platelet MAO activity; triiodothyronine; testosterone; Psykiatri; Psychiatry; Psykiatri; Psychiatry; psykiatri;

    Abstract : The aim of this investigation was to determine the frequency of psychopathy and examine the co-morbidity pattern in a forensic psychiatric population in Sweden. In addition, possible biological markers were evaluated. The research subjects were 61 non-psychotic men, admitted for forensic psychiatric investigations in Uppsala during 1992 - 1994. READ MORE
