1. The relationship between oestrogen and muscle strength: a current perspective
The relationship between muscle strength and oestrogen is ambiguous and is still largely unresolved. The evidence for and against an effect of oestradiol on determinants of muscle function is equivocal and often contradictory. The bulk of the research in this area was performed during the eighties and nineties, using models of reproductive functioning such a

2. Genistein-induced fluid accumulation in ovariectomised rats' uteri is associated with increased cystic fibrosis transmembrane regulator expression
OBJECTIVE: High genistein doses have been reported to induce fluid accumulation in the uteri of ovariectomised rats, although the mechanism underlying this effect remains unknown. Because genistein binds to the oestrogen receptor and the cystic fibrosis transmembrane regulator mediates uterine fluid secretion, we hypothesised that this genistein effect invo

3. Expressão imunohistoquímica de receptores para estrogênio e progesterona nas fases aguda e crônica da esquistossomose mansônica experimental em camundongos
INTRODUÇÃO: A responsabilidade do Schistosoma mansoni em esterilidade feminina é ainda controversa. Este estudo é conduzido para avaliar o efeito da esquistossomose mansoni aguda e crônica no endométrio usando análise de imuno-histoquímíca da expressão de receptor hormonal uterina. MÉTODOS: Vinte e quatro camundongos fêmeas albinas suíças não

4. Estudo da relaÃÃo entre a atividade anti-tumoral in vitro do Ãcido Ãsnico e a ativaÃÃo da via metabÃlica p53
Usnic acid is a metabolite of lichen that exerts a wide variety of biological activities including cytotoxicity against cells derived from human malignant tumours. Although cytotoxicity of usnic acid has been extensively reviewed, its mechanism of action is still unclear. There are no data in the literature about the involvement of the tumour suppressor p53

5. Análise da expressão diferencial de genes do folículo ovariano de fêmeas pré-púberes e púberes Bos primigenius indicus (Nelore) por meio da Análise Serial de Expressão Gênica (SAGE) / Analysis of differential gene expression of ovarian follicle from prepubertal and pubertal Bos primigenius indicus (Nelore) females by Serial Analysis of Gene Expression (SAGE)
Puberty is the stage where any mammal, male or female, becomes able to produce viable gametes and manifest complete sexual behavior. These are results from the gradative adjustment between the increase in gonadotrophic activity and the ability of gonads in undergoing simultaneously both steroidogenesis and gametogenesis. One of the major factors interferring

6. Estudo de metaloproteinases de matriz e colageno no processo de reparo osseo alveolar em ratas osteoporoticas por ooforectomia
Osteoporosis is a metabolic bone disease of multifatorial aetiology commonly associated with oestrogen deficiency. The effects of osteoporosis on bone structure of the oral cavity have scarcely studied but there are evidences of delayed healing process after tooth extraction in ovariectomized rats. The increased life span of most world populations and the co

7. Schizophrenia: do men and women suffer from the same disease?
This article reviews the literature on normal brain development and behavioural development in men and women as well as on aetiological risk factors for schizophrenia, such as pre-, peri- and postnatal complications. The male-female comparisons of age and type of onset, symptomatology, course and outcome were based on a population-based sample of 232 first i

8. Differential expression of oestrogen receptor and oestrogen inducible genes in gastric mucosa and cancer.
BACKGROUND: Evidence exists for a role for oestrogen in gastric cancer. The incidence of gastric cancer is much higher in men than in woman, and a similar sex difference is also seen in a rat experimental model of gastric cancer. AIMS: Evidence for a functional oestrogen receptor in normal gastric mucosa and cancer has been sought. METHODS: Oestrogen recepto

9. Type II oestrogen binding sites in human colorectal carcinoma.
Seven cases of colorectal adenocarcinomas were investigated for the presence of oestrogen receptors and progesterone receptors. The tumours specifically bound oestradiol. This binding almost exclusively resulted from the presence of high numbers of type II oestrogen binding sites. Oestrogen receptors were absent or present at very low concentrations. Immunoh

10. Oestrogen and progesterone receptor expression in mammary fibromatosis.
AIMS--To investigate the oestrogen and progesterone receptor concentrations expressed on mammary fibromatoses to determine their responsiveness to oestrogenic stimuli. METHODS--Six mammary fibromatoses were examined using immunohistochemistry for the presence of oestrogen and progesterone receptors using antibodies against the receptor proteins. Enzyme immun

11. Oestrogen regulates cathepsin D mRNA levels in oestrogen responsive human breast cancer cells.
A cDNA library was constructed from the mRNA of the ZR-75 oestrogen responsive human breast cancer cell line and screened for oestrogen regulated mRNA sequences. Of the recombinants isolated, 30 contained cDNA that corresponded to a single mRNA species of 2.1 kb that was induced between 10 and 15 fold by oestradiol treatment. The sequence of the entire open

12. Immunohistochemical quantitation of oestrogen receptors and proliferative activity in oestrogen receptor positive breast cancer.
AIM--To evaluate the effect of the duration of formalin fixation and of tumour heterogeneity on quantitative estimates of oestrogen receptor content (oestrogen receptor index) and proliferative activity (MIB-1 index) in breast cancer. METHODS--Two monoclonal antibodies, MIB-1 and oestrogen receptor, were applied to formalin fixed, paraffin wax embedded tissu
