13. Exposição precoce ao poluente 1,2-naftoquinona (1,2-NQ) e a susceptibilidade diferencial à inflamação pulmonar em camundongos C57BL/6 machos e fêmeas. / Early exposure to the pollutant 1,2-naphthoquinone (1,2-NQ) and differential susceptibility to lung inflammation in male and female C57BL / 6 mice.
Avaliou-se neste estudo a influência da exposição precoce ao poluente 1,2-NQ na resposta inflamatória alérgica em camundongos C57BL/6 machos e fêmeas, na juventude. Tanto nas fêmeas quanto em machos a 1,2-NQ não afetou a hiperreatividade (HR) nas vias aéreas. A HR foi maior nas fêmeas alérgicas, na ausência ou presença da 1,2-NQ. Camundongos mac

14. Influence of the female sexual hormones about the pulmonary allergic inflammation in model murino of chronic asthma. / Influência dos hormônios sexuais femininos sobre a inflamação alérgica pulmonar em modelo murino de asma crônica.
We evaluated the influence of female sex hormones on the pulmonary alergic asthma in a experimental chronic asthma model.Groups: Basal, (non-manipulated animals), Ovx (Ovariectomized) and Sham- Ovx/ allergic ( animals subjected to similar manipulations except for the ovaries removal) sensitized 7 days after ovarietcomy and challenged with OVA after the 21st

15. Avaliação da expressão de moléculas co-estimuladoras na superfície de células dendríticas de fêmeas ovariectomizadas em modelo murino de asma / Evaluation of expression of co-stimulatory molecules on dendritic cells surface of ovariectomized females in murine model of asthma
The trigger and the maintenance of asthma are influenced by immune system and its sensibilization. Antigen processing and antibody generation implicate on the allergic response development observed in asthmatic subjects. Results obtained in our laboratory showed that the female sex hormones oscillation during sexual cycle influences on the worsening of asthm

16. Parâmetros mecânicos, físicos e químicos na avaliação de mandíbulas de ratos deficientes em esteróides sexuais / Mechanical, physical and chemical parameters in mandible evaluation of sex steroid deficiency rats
The increase in the life expectancy has been raising the occurrence of common degenerative alterations in aging population, as osteoporosis. This systemic disease is also frequent in hypogonadism and affects the bone metabolism, included mandibular bone. The aim of this study was to evaluate how sex steroid deficiency, induced by orchiectomy (ORX) or ovariec

17. Comparison of serum hormone levels of captive and free-living maned wolves Chrysocyon brachyurus
Serum hormone levels were compared between captive and free-living maned wolves and seasonal variations of sex hormones were studied. Blood samples were collected from 16 male and 26 female adult animals from Brazilian zoos, and from 30 male and 24 female free-living adults to determine serum progesterone and testosterone by radioimmunoassay. Serum testoster

18. Effect of sex and sex hormones on formalin-induced temporomandibular joint inflammation / Influencia do sexo e dos hormonios sexuais na inflamação induzida pela administração de formalina na articulação teporomandibular de ratos
The greater prevalence of pain conditions in temporomandibular joint and inflammatory diseases in female suggests the involvement of sex hormones in temporomandibular joint pain and inflammation. Previous studies suggest that the high estradiol level during the rat estrous cycle and the administration of estradiol or progesterone in ovariectomized female or

19. Avaliação da influencia dos hormonios sexuais na nocicepção da articulação temporomandibular de ratos e estudo dos mecanismos envolvidos / The role of sex hormones in temporomandibular joint nociception and study of the mechanisms involved
The aim of this study was to evaluate the effect of sex hormones on temporomandibular joint (TMJ) nociception in rats and the possible mechanisms underlying their effect. The TMJ injection of 0.5% formalin induced nociception in intact females and gonadectomized males, but not in intact males, suggesting that the physiological level of testosterone protect m

20. Efeitos das isoflavonas da soja (Glycine max) na síntese de fatores vasoativos derivados de células endoteliais humanas da linhagem ECV304 / Effects of soy isoflavones (Glycine max) in the synthesis of vasoactive factors derived from human endothelial cells line ECV304.
During their reproductive years, women have a lower incidence of coronary heart disease (CHD) compared to men of similar age. However, this advantage disappears in post-menopause, suggesting that female sex hormones exert some cardio protective effect. One of the mechanisms proposed to explain this protection is the fact that estrogens promote the production

21. Análise da expressão gênica em Schistosoma mansoni induzida pelo pareamento sexual e pelo sexo do hospedeiro através da técnica dos microarranjos de DNA
The parasitic trematode Schistosoma mansoni is one of the major causative agents of Schistosomiasis, a disease that affects approximately 200 million people, mostly in developing countries. Since much of the pathology is associated with eggs laid by the female worm, understanding the mechanisms involved in oogenesis and sexual maturation is an important step

22. Efeito da terapia estrogênica sobre o controle autonômico da freqüência cardíaca e a capacidade aeróbia de mulheres saudáveis.
The effects of female sex hormones on the cardiovascular system have been the topic of much discussion and controversy in the literature. Nevertheless, many scientists believe that estrogens play an important cardioprotective role in premenopausal women, with their effects being observed directly on blood vessels or indirectly by the promotion of an antiathe

23. Morpho-functional characteristics of sex reversal in Synbranchidae (Teleostei: Synbranchiformes) / Perfil morfo-funcional da inversão de sexo em Synbranchidae (Teleostei: Synbranchiformes)
Teleost fishes exhibit several sexual patterns during their ontogeny, in which the gonads change into functional ovaries or testes. In distinct Orders, both gonochoristic and hermaphrodite species, simultaneous as well as sequential or consecutive, can be found. In sequential hermaphroditism (protandrous or protogynous), sex change in adult individuais invol

24. Spontaneous inflammatory pelvic disease in adult non-castrated female rats treated with estrogen
The adaptive immune response of the genital tract is under the control of sexual steroids; however, the influence of sex hormones on innate immune mechanisms of the genital mucosa are only beginning to be understood. We found that long-term estrogen treatment increases the risk for inflammatory pelvic diseases in adult non-castrated female rats. Female rats
