Lack of genotoxicity induced by endogenous and synthetic female sex hormones in peripheral blood cells detected by alkaline Comet assay
(Wiley-Blackwell, 2007-06-01)
The etiology of hormone-induced cancers has been considered to be a combination of genotoxic and epigenetic events. Currently, the Comet assay is widely used for detecting genotoxicity because it is relatively simple, ...
Influence of estrous cycle hormonal fluctuations and gonadal hormones on the ventilatory response to hypoxia in female rats
(2017-10-01)
Sex hormones may influence many physiological processes. Recently, we demonstrated that hormonal fluctuations of cycling female rats do not affect respiratory parameters during hypercapnia. However, it is still unclear ...
When Hormone Defects Cannot Explain It: Malformative Disorders of Sex Development
(Wiley, 2014-12)
The birth of a baby with malformations of the genitalia urges medical action. Even in cases where the condition is not life-threatening, the identification of the external genitalia as male or female is emotionally essential ...
Sex hormone binding globulin: Expression throughout early development and adult pejerrey fish, Odontesthes bonariensis
(Academic Press Inc Elsevier Science, 2017-02)
Sex hormone binding globulin (Shbg) is a plasma glycoprotein that binds and transports steroids in the blood of all vertebrate classes apart from birds. In the present study we characterized shbg from pejerrey, a fish ...
Role of estrogen and other sex hormones in brain aging: Neuroprotection and DNA repair
(Frontiers Research Foundation, 2017-12)
Aging is an inevitable biological process characterized by a progressive decline in physiological function and increased susceptibility to disease. The detrimental effects of aging are observed in all tissues, the brain ...
Influence of endogenous and synthetic female sex hormones on human blood cells in vitro studied with comet assay
(2007-08-01)
The comet assay has been conducted with numerous cell lines to assess in vitro genotoxicity. In order to use the comet assay as part of an in vitro test for evaluating genotoxicity, however, there are cell-specific factors ...
Senescence and steroid hormone receptor reactivities in accessory sex glands of elderly rats (Sprague-Dawley) following exogenous hormonal therapy
(Churchill LivingstoneEdinburghEscócia, 2012)
Associations Between Sex Hormone Levels and Periodontitis in Men: Results From NHANES III
(Amer Acad Periodontology, 2015-10-01)
Background: Sex hormones are linked to inflammation and bone turnover. The goal of this study is to explore the association between sex hormone levels and periodontitis in men using data from the third National Health and ...
Involvement of pituitary gonadotropins, gonadal steroids and breeding season in sex change of protogynous dusky grouper, Epinephelus marginatus (Teleostei: Serranidae), induced by a non-steroidal aromatase inhibitor
(2013-10-01)
Two experiments were performed using the aromatase inhibitor (AI) letrozole (100mg/kg) to promote sex change, from female-to-male, in protogynous dusky grouper. One experiment was performed during the breeding season ...
Hypoxic and hypercapnic ventilatory responses in rats with polycystic ovaries
(Elsevier B. V., 2015)
In female rats, a single injection of estradiol valerate (EV) results in effects that are similar to those observed in women with polycystic ovary syndrome (PCOS). We hypothesized that EV-induced PCOS affects breathing ...
