Relationships Between Plasma Levels of Organochlorines, Retinol and Thyroid Hormones from Polar Bears (Ursus maritimus) at Svalbard
Associations were determined between retinol and the thyroid hormones thyroxine (T4) and triiodothyronine (T3), respectively, and the organochlorine contaminants (OCs) polychlorinated biphenylsExpand
Prevalence and predictors of vitamin D deficiency in five immigrant groups living in Oslo, Norway: the Oslo Immigrant Health Study
There is widespread vitamin D deficiency in both men and women born in Turkey, Sri Lanka, Iran, Pakistan and Vietnam residing in Oslo, and it is higher in men born in Pakistan and lower in those born in Vietnam compared to the other ethnic groups. Expand
Increased neuroendocrine response to a repeated bout of endurance exercise.
A more pronounced neuroendocrine response to a second bout of exercise on the same day compared with a first/single bout is demonstrated, involving both the sympatho-adrenal system and the hypothalamo-pituitary-adsrenal axes. Expand
Neuropsychological function in relation to serum parathyroid hormone and serum 25–hydroxyvitamin D levels
A deranged calcium metabolism appears to be associated with impaired function in several tests of neuropsychological function in subjects with secondary hyperparathyroidism. Expand
Effect of rhEPO administration on serum levels of sTfR and cycling performance.
Serum levels of sTfR may be used as an indirect marker of supranormal erythropoiesis up to 1 wk after the administration of rhEPO, but the effects on endurance performance outlast the increase in sTFR. Expand
High prevalence of the hemochromatosis-associated Cys282Tyr HFE gene mutation in a healthy Norwegian population in the city of Oslo, and its phenotypic expression.
Fifteen per cent of a healthy Norwegian population is heterozygous for the HFE gene mutation C282Y, which is among the highest reported prevalence values among healthy individuals. Expand
Androgen replacement and quality of life in patients treated for bilateral testicular cancer.
Current standard intramuscular ARP is not optimal in approximately 1/3 of the patients who have undergone bilateral orchiectomy for testicular cancer, particularly if scheduled at > or = 3 week intervals, and Schedules for ARP have to be improved. Expand
Severe deficiency of 1,25-dihydroxyvitamin D3 in human immunodeficiency virus infection: association with immunological hyperactivity and only minor changes in calcium homeostasis.
It is concluded that inadequate 1alpha-hydroxylation of 25-hydroxyvitamin D seems to be the most likely cause of 1,25-(OH)2D deficiency in HIV-infected patients, possibly induced by an inhibitory effect of TNFalpha. Expand
Smoking is associated with lower bone mineral density and reduced cortical thickness in young men.
Smoking was associated with lower aBMD and reduced cortical thickness in young men and adjustment for testosterone and/or 25-OH-vitamin D levels did not alter the associations between smoking and bone parameters. Expand
Cross-sex pattern of bone mineral density in early onset gender identity disorder
It is reported that body composition and bone density of EO-GID patients show less pronounced sex differences compared to controls and that bone density was unaffected by cross-sex hormone treatment. Expand
