BINDING OF RADIOGRAPHIC CONTRAST MEDIA TO SERUM PROTEINS A clinical and experimental investigation of their adverse effects through influence on active steroid hormone levels. by Staffan Wirell, M.D., Department of Diagnostic Radiology, University Hospital of Umeå, S-901 85 Umeå, Sweden. Summary of thesis based on the following papers: I Wirell S.: Adverse reactions at intravenous cholegraphy w...

Maternal transfer of nutrients, including steroid hormones, to embryos during gestation in viviparous amniotes is well known, but the concordant process in oviparous amniotes is poorly understood. Recent evidence suggests that steroid hormones are present in freshly laid eggs of archosaurs and that their concentrations may influence offspring phenotypes. This process might be especially importa...

Sex differences in attachment styles have been found in adulthood, emerge as early as middle childhood, and can be sizable when described at the appropriate level of analysis. However, they have received relatively little attention in mainstream attachment research. Here I review the evidence of sex differences in attachment, including what is currently known about developmental patterns and cr...

OBJECTIVE Gender differences in the neurodevelopmental disorder, schizophrenia, have been described for nearly all features of the illness. Reduced hippocampal expression of the GABAergic interneuron marker, parvalbumin (PV), and GABA synthesizing enzyme, GAD67, are consistently reported in schizophrenia. However, little is known of the expression patterns of hippocampal PV and GAD67 during ado...

Several clinical and experimental studies have demonstrated gender dimorphism in immune and organ responsiveness and in the susceptibility to and morbidity from shock, trauma, and sepsis. In this respect, cell-mediated immune responses have been shown to be depressed in males following trauma-hemorrhage, whereas they were aintained/enhanced in proestrus females. Furthermore, sex hormones have b...

Opioid abuse risk In recent years, there has been growing interest and increasing recognition that sex and gender may play a significant role in a person’s response to medication and should be an important part of individual prescribing. The reasons for sex differences in medication response are clearly multifactorial, encompassing a wide range of aspects from the effects of sex steroid hormone...

Little is known about the role of the endocrine system in financial decision-making. Here, we survey research on steroid hormones and their cognitive effects, and examine potential links to trader performance in the financial markets. Preliminary findings suggest that cortisol codes for risk and testosterone for reward. A key finding of this endocrine research is the different cognitive effects...

background: one of the new methods for elimination or destruction of estrogen hormones is ultrasound irradiation. the aim of this study was to determine the main mechanism of steroid hormones removal by ultrasound. methods: in this study, estrogen (e1) and 17 beta-estradiol (e2) were irradiated with ultrasound at different frequencies, powers, and exposure times in two cases: with and without b...

The song system of zebra finches (Taeniopygia gutatta) is highly sexually dimorphic. Only males sing, and the brain regions and muscles controlling song are much larger in males than in females. Development of the song system is highly sensitive to steroid hormones. However, unlike similar sexually dimorphic systems in other animal models, masculinization of song system structure and function i...

The effects of various substrates on the binding of agonists to muscarinic receptors were studied in the rat hypothalamus and adenohypophysis by competition experiments using the highly specific tritiated muscarinic antagonist N-methyl-4-piperidyl benzilate. It was found that agonist binding properties were affected only by the steroid sex hormones (beta-estradiol and progesterone), both of whi...
