13. Impacto do perfil alimentar e genotipico do sistema glutationa S-transferase na susceptibilidade ao cancer / Impact of diet and glutathione s-transferase system genotype in the susceptibility to cancer
Background: Glutathione-S-Transferase gene family has an important role in the biotransformation and detoxification of different xenobiotics and endogenous compounds. The high admixture of the Brazilian population may represent a unique model in which the types and frequency of genetic polymorphisms of GST enzymes are less influenced by ethnicity. Objective:

14. Phenotype characterization of the mucinous ovarian tumors / Caracterizaçao fenotípica dos tumores mucinosos do ovário
NTRODUÇÃO: Neoplasias mucinosas primárias do ovário apresentam muitos pontos de controvérsias em relação ao seu padrão de diferenciação, sendo classificadas como tumores benignos, borderline e malignos.Elas também são classificadas em diferentes fenótipos, recentemente designadas como gastrointestinal e seromucinoso. Sua heterogeneidade tem prod

15. Produção de óxido nítrico e expressão da enzima sintase de óxido nítrico em tumores ovarianos císticos.
Introdução: O óxido nírico (NO) é um mensageiro biológico sintetizado pelo aminoácido Larginina pela ação da enzima sintase de óxido nítrico (NOS). A NOS neuronal e a endotelial são constitutivas em muitos tipos celulares, enquanto a NOSi é induzida em leucócitos, células endoteliais e outros tipos celulares após a estimulação por endotoxin

16. Pharmacokinetics and tumor uptake of a derivatized form of paclitaxel associated to a cholesterol-rich nanoemulsion (LDE) in patients with gynecologic cancers / "Farmacocinética e captação tecidual do paclitaxel associado à nanoemulsão (LDE) em pacientes com neoplasias malignas do trato genital feminino"
O paclitaxel é utilizado amplamente no carcinoma de ovário, nos casos refratários de carcinoma de endométrio e quimioterapia exclusiva para carcinoma avançado de colo uterino. A associação de paclitaxel a uma nanoemulsião rica em colesterol, denominada LDE, mostrou toxicidade menor e aumento da atividade antitumoral do fármaco em cobaias. No present

17. Istoadenoma do ducto biliar comum
Biliary duct cystoadenomas are rare neoplasms, with about 120 cases described in the literature, including cystoadenomas and cystoadenocarcinomas. The authors report a case of cystoadenoma of the common bile duct in a 45-year-old woman with history of jaundice. Ultrasound revealed a cystic mass located in the common bile duct. Endoscopic retrograde cholangio

18. A case-control study of benign ovarian tumours.
STUDY OBJECTIVE--The aim was to investigate the association between reproductive, contraceptive, and menstrual factors and risk of benign ovarian tumours. DESIGN AND SETTING--This was a case-control study carried out in six London Hospitals. An interviewer administered questionnaire was used. SUBJECTS--62 women with a benign epithelial ovarian neoplasm, 37 w

19. A study of the Ca antigen in epithelial tumours of the ovary.
The expression of Ca antigen in ovarian epithelial tumours has been studied by an immunohistochemical technique using the Ca 1 monoclonal antibody. The antigen was found to be present in some examples of each of the histological subtypes of ovarian epithelial neoplasms and was detected in benign, borderline and malignant tumours. It is concluded that the pre

20. Absence of human papillomavirus sequences in ovarian pathologies.
The role of human papillomaviruses (HPVs) in ovarian epithelium (either normal or neoplastic) remains controversial. We have investigated by PCR the presence of HPV DNA in fresh tissue from ovarian neoplasms and in primary cell cultures established from either normal, benign or malignant ovarian surface epithelia. None of the fresh samples and primary ovaria

21. Ovarian neoplasms, functional ovarian cysts, and oral contraceptives.
The incidence of ovarian neoplasms and functional ovarian cysts diagnosed at laparotomy or laparoscopy among the 17,000 women taking part in the Oxford Family Planning Association contraceptive study was investigated. Epithelial cancer of the ovary was only 25% as common among those who had ever taken oral contraceptives as those who had never done so (95% c

23. Early events in ovarian oncogenesis
Ovarian cancer represents the most lethal of the gynecological neoplasms. The molecular and genetic events associated with early ovarian oncogenesis are still largely unknown, thus contributing to the lack of reliable biomarkers for disease detection. Since the majority of ovarian tumors are diagnosed at an advanced stage, the availability of early ovarian c

24. Reactivity of a monoclonal antibody with human ovarian carcinoma.
A murine monoclonal antibody (OC125) has been developed that reacts with each of six epithelial ovarian carcinoma cell lines and with cryopreserved tumor tissue from 12 of 20 ovarian cancer patients. By contrast, the antibody does not bind to a variety of nonmalignant tissues, including adult and fetal ovary. OC125 reacts with only 1 of 14 cell lines derived
