1. The influence of phytoestrogens or estrogens on the proliferation of the rat endocervical mucosa
RESUMO INTRODUÇÃO Embora a terapia estrogênica seja amplamente utilizada contra sintomas pós-menopausais, ela pode apresentar efeitos adversos, incluindo câncer de mama e endometrial. Assim, as isoflavonas da soja são consideradas uma alternativa possível à terapia estrogênica. No entanto, ainda há controvérsias se estes compostos exercem efeito

2. A Fast Chromatographic Method for Determination of Daidzein and Genistein in Spiked Water River Samples Using Multivariate Curve Resolution
This work reports the development of a fast chromatographic methodology for quantitation of two phytoestrogens: daidzein (DAI), and genistein (GEN), in river water samples. The proposed method is based on high performance liquid chromatography-diode array detection (HPLC-DAD) data, and multivariate curve resolution-alternative least square (MCR-ALS) secon

3. In vitro isoflavonoid production and analysis in natural tetraploid Trifolium pratense (red clover) calluses
Isoflavones are polyphenolic phytoestrogens, predominantly found in leguminous plants. Trifolium pratense L., Fabaceae (red clover), is rich in isoflavones that possess estrogenic activity due to their similar molecular structure and effectiveness in preventing health conditions such as menopause, osteoporosis, cardiovascular disease, hypertension and hormon

4. Avaliação do efeito do extrato de soja (Glycine max) biotransformado pelo fungo Aspergillus awamori em cultura de células de cêncer de mama estrógeno-dependente e independente / Effect of Soy Extract (Glycine max) biotransformed by the fungus Aspergillus awamori in cultured breast cancer cells estrogen-dependent and independent.
Introdução: Isoflavonóides são compostos encontrados em vários vegetais e apresentam diversos efeitos farmacológicos. Dentre estes compostos, encontramos os fitoestrógenos, assim chamados por possuírem ações que mimetizam o efeito do estrógeno natural sobre as células. A soja (Glycine max), um dos vegetais ricos nos fitoestrógenos daidzeína e g

5. EFEITO DA GENISTEÍNA NA FUNCIONALIDADE DE MACRÓFAGOS: UM ESTUDO COMPARATIVO ENTRE RATOS MACHOS E FÊMEAS
Genistein has estrogenic activity and can bind to estrogen receptors (ER), so it is considered a phytoestrogen. ER have been reported in macrophages and in that sense, the estrogens modulate immune responses. Despite the sexual dimorphism of the immune responses in females and males is well established, there are few studies that elucidate the role of bioact

6. Atividade anticâncer in vitro e in vivo de Psidium guajava L. (nome popular: goiabeira) / Psidium guajava L. (popular name guava) in vitro and in vivo anticancer activity
Anticancer drug research based on screening of natural sources enabled the discovery of several drugs that are used in cancer treatment. This project aimed to evaluate the in vitro and in vivo anticancer activity of Psidium guajava L. (popular name: guava), elected for its ethnopharmacological use for antiparasitic activity. After harvesting, the vegetal mat

7. AVALIAÇÃO DO EFEITO ESTROGÊNICO DO GINKGO BILOBA EM RATAS WISTAR IMPÚBERES
The use of hormonal therapy in menopause is not absent of risks being related to adverse effects such as pulmonary embolism and cancer due to its use. In these cases, phytoestrogens, the estrogenic compounds present in plants, can be used as an alternative to the hormonal treatment. There is already proof of efficacy and safety in their use. Ginkgo biloba ex

8. AVALIAÇÃO DO EFEITO PROTETOR DO EXTRATO DE Ginkgo biloba NA OSTEOPOROSE INDUZIDA POR GLICOCORTICÓIDE EM RATAS WISTAR
Introduction: Osteoporosis is a disease characterized by the reduction of bone volume. Among the main causes of osteoporosis is the reduction of the levels of estrogen and the chronic use of glucocorticoids. Several products are used on the osteoporosis treatment, including natural products, among them some promising alternatives as the phytoestrogens. In vi

9. 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

10. 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

11. Avaliação do efeito imunomodulador da isoflavona genisteína na encefalomielite autoimune experimental murina
Multiple sclerosis (MS) is the most common non-traumatic, disabling neurological human inflammatory demyelinating disease of the CNS. Experimental autoimmune encephalomyelitis (EAE) models MS and is characterized as a CD4+ Th1 cell-mediated autoimmune disease. Recent data show that estrogen plays a pivotal role in the immune response as well as in immune-med

12. Efeitos da exposição a isoflavonas da soja sobre a saude reprodutiva de coelhos machos / Effects of exposure to soy isoflavones on the reproductive health of male rabbits
Este estudo foi proposto para avaliar se a exposição perinatal (gestacional e lactacional) ou crônica a isoflavonas em dieta contendo soja ou na forma de concentrados de isoflavonas pode comprometer a saúde reprodutiva de coelhos machos. No primeiro experimento, fêmeas foram alimentadas com dieta contendo soja ou dieta isenta de soja e alfafa, suplement
