1. BIOCHEMICAL ANALYSIS AND BONE REMODELING IN RESPONSE TO OOPHORECTOMY AND AQUATIC TRAINING
ABSTRACT Objective: To investigate whether swimming could prevent bone loss and could be indicated to assist in treatment of osteoporosis. Methods: Female rats were divided into 4 groups (n=6), two of them were oophorectomized. Animals from two groups, one oophorectomized and another not oophorectomized, underwent aquatic training for eight weeks. After tr

2. Perfil dos esteroides gonadais e expressão dos hormônios folículo estimulante (FSH) e luteinizante (LH) durante a inversão sexual de Epinephelus marginatus (Teleostei: Serranidae), hermafrodita protogínico, utilizando-se inibidor de aromatase / Gonadal steroids profile and expression of follicle-stimulating (FSH) and luteinizing (LH) hormones during the sex reversal of Epinephelus marginatus (Teleostei: Serranidae) hermaphroditic protogynous, using aromatase inhibitor
A plasticidade do desenvolvimento gonadal em peixes, que contrasta com os padrões mais estáveis encontrados nos demais vertebrados, deu origem a várias questões intrigantes relativas tanto ao seu significado adaptativo quanto aos fatores genéticos e fisiológicos que modulam o processo. A inversão do sexo em peixes hermafroditas seqüenciais (protândr

3. Gender-dependent effects of aging on the kidney
It is well known that the kidney plays an important role in the development of cardiovascular diseases such as hypertension. The normal aging process leads to changes in kidney morphology, hemodynamics and function, which increase the incidence of cardiovascular events in the elderly population. These disturbances are influenced by several factors, including

4. Testosterona, estradiol e doença arterial coronariana em homens adultos. / TESTOSTERONE, ESTRADIOL AND CORONARY ARTERY DISEASE IN MEN.
Introduction: Cardiovascular diseases (CVDs) represent the main cause of death in Brazil, and among them especially the coronary artery diseases (CADs). Men present higher incidence and mortality rates for CAD than women. One of the explanations for this fact may be the possibly deleterious effect of testosterone on the male cardiovascular system and the pro

6. Esteróides gonadais e metabolismo lipídico ao longo do ciclo reprodutivo de Arapaima gigas (SCHINZ, 1822) em ambiente natural / Gonad steroids and lipid metabolism along the reproductive cycle of Arapaima gigas (SCHINZ, 1822) in natural environmet
The aim of the present study was to investigate the possible physiological alterations related with reproduction in males and females of Arapaima gigas (pirarucu) in their natural environment. Pirarucu is an obligatory aerial respiration species belonging to a very ancient group of teleosts and inhabits Amazonian river. The main goals of this study were to d

7. 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

8. ESTABELECIMENTO DE CONDIÇÕES ANALÍTICAS PARA DETERMINAÇÃO DE HORMÔNIOS ESTRÓGENOS EM ÁGUA POTÁVEL DISTRIBUÍDA NA CIDADE DE SÃO LUÍS-MA / ESTABLISHMENT OF ANALYTICAL CONDITIONS FOR DETERMINATION Of THE HORMONE ESTROGEN DISTRIBUTED IN DRINKING WATER CITY OF SÃO LUIS-MA
Given the humanity perception of necessity to preserve the environment and the incessant search for sustainable development, today the preservation of natural water sources is by far one of the most worrying factors for the preservation of life. Besides the most common aquatics pollutants, also there is one called emerging pollutants, which in recent decades

10. Parasitic castration, growth, and sex steroids in the freshwater bonefish Cyphocharax gilbert (Curimatidae) infested by Riggia paranensis (Cymothoidea)
Cyphocharax gilbert exibe castração parasitária quando está infestado pelo crustáceo Riggia paranensis, estando impossibilitado de reproduzir. Os peixes foram coletados no trecho médio do rio Itabapoana, Brasil, para analisar a prevalência do parasitismo, quantificar crescimento e as concentrações de esteróides sexuais, considerando o tamanho do co

11. Interferentes endócrinos no ambiente
Although the hypothesis that environmental chemicals may exhibit endocrine disrupting effects is not new, the issue has been a growing level of concern due to reports of increased incidences of endocrine-related disease in humans, including declining male fertility, and more significantly, to adverse physiological effects observed in wildlife where cause and

12. Sex differences in angiotensin II- induced hypertension
Sex differences in the development of hypertension and cardiovascular disease have been described in humans and in animal models. In this paper we will review some of our studies which have as their emphasis the examination of the role of sex differences and sex steroids in modulating the central actions of angiotensin II (ANG II) via interactions with free
