13. Expressão de fator de crescimento transformador Beta e inibidores teciduais de metaloproteinases 1 e 2 em próstatas caninas normais e com lesões proliferativas / Expression of tansforming growth factor B and tissue inhibitor of metalloproteianse 1 and 2 in normal canine prostates and with proliferative lessions
The canine gland has drawn interest for research due to its similarities with the human prostate and the great incidence of lesions. Moreover, the canine prostate shows high incidence of diseases. The main lesions that affect the prostate are prostatitis, benign prostatic hyperplasia (BPH), cysts and adenocarcinoma. Recently attention has been given to lesio

14. Initial Brazilian experience in the treatment of localized prostate cancer using a new generation cryotechnology: feasibility study
INTRODUCTION: The objective of our study is to present the first Brazilian cryoablation experience in the treatment of low and intermediate risk localized prostate cancer using 3rd generation cryoablation and real-time biplanar transrectal ultrasonography. MATERIALS AND METHODS: Ten Brazilian patients underwent primary cryoablation for localized prostate can

15. Antioxidant supplementation decreases the cell death rate in the prostatic stromal tissue of long-term castrated rats
OBJECTIVE: The purpose of this study was to compare the effects of castration on cell death rate of the adult rat prostates and to evaluate the benefic action of alpha tocopherol supplementation to avoid apoptosis post-orchiectomy. MATERIAL AND METHODS: Thirty male Wistar rats weighing 250-300g were divided into three groups: group I - they were subjected to

16. Efeitos de uma desintegrina RGD recombinante de Rhinocerophis alternatus (Bothrops alternatus) na migração de células normais e tumorais
Cell migration, invasion of the surrounding tissues, blood vessels and proliferation are cellular processes involved in metastases. These events are mediated by integrins, adhesion receptors present on cell surfaces and responsible for the extracellular matrix and cells binding. Disintegrins, snake venoms polypeptides, are known to inhibit integrins action,

17. Influência da hiperglicemia e do estresse oxidativo na cinética de proliferação e morte celular no epitélio acinar da próstata de ratos diabéticos / The influence of hyperglycemia and oxidative stress in proliferation and cell death kinetics in prostate acinar epithelium of diabetic rats
The diabetes damages in prostate morphophysiology are well known and are triggered by insulin lack, low androgen levels and hyperglycemia. Previous researches showed an individual variation in morphological prostate response against this disease. In order to clarify the factors responsible for this variation, we examined the correlation between histological

18. Controle hormonal da próstata feminina do gerbilo sob influência de múltiplas prenhezes e reposição hormonal / Hormonal control of the gerbil s female prostate : influence of multiple pregnancies and hormone replacement
The gerbil female prostate is located paraurethrally and has all the main histological components of the male prostate, like secretor epithelium and fibromuscular stroma. This gland, like the prostate in males, is targeted by testosterone action, which promotes morphofunctional development. Furthermore, estrogens are required to maintain the male and female

19. Investigação dos genes APEX1, XRCC1, PSA e AR como candidatos a marcadores moleculares para o câncer de próstata
O câncer de próstata é o segundo tipo de câncer mais incidente no Brasil. Dentre os genes de interesse relacionados com esta neoplasia, destacam-se os participantes da via dos andrógenos, como o Receptor de Andrógeno (AR), o Antígeno Específico da Próstata (PSA) e os da via de reparo a danos no DNA (APEX1 e XRCC1). Polimorfismos nesses genes são fr

20. Impact of infection on the secretory capacity of the male accessory glands
INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT) on the male accessory gland function are controversial. MATERIAL AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 gro

21. Perfis das distroglicanas e morfo-fisiologia do lobo ventral da prostata de camundongos distroficos / Dystroglycans and laminin BETA 3 features on the prostate of mdx mice
The prostate is a fundamental accessory sex gland for the male reproductive process and the stroma-epithelium interaction has an important role in prostate structural maintenance and function. The basal membrane is an interaction link, offering mechanical and physiological support. Nowadays, different studies suggest that dystroglycan (DG), which is an adhes

22. Aspectos morfofuncionais da prostata feminina do gerbilo durante o cilco estral : estudos estruturais e caracterização do perfil secretor / Morphofunctional aspects of the gerbil female prostate during the estrous cycle : structural analysis and characterization on the secretory profile
The prostate is not an exclusive organ of the male reproduction system, found in females of several rodents species and also in humans. The female prostate has been considered homologue to the male ventral prostate and it is formed by a small cluster of glands and ducts inserted into a fiber muscular stroma. In adult female Mongolian gerbils (Meriones unguic

23. Prostasin, a potential tumor marker in ovarian cancer: a pilot study
INTRODUCTION: Ovarian cancer is generally diagnosed at advanced stages of the disease; therefore, poor prognoses are typical. The development of tumor markers is thus of utmost importance. Prostasin is a protease that in normal tissues is highly expressed only in the prostate gland and seminal fluid. A previous study showed that prostasin is highly overexpre

24. The role of extended prostate biopsy on prostate cancer detection rate: a study performed on the bench
INTRODUCTION: The aim of this prospective study was to compare the advantage of performing prostate biopsy with a greater number of cores using the classic sextant procedure, with the aim of reducing false negative results. MATERIALS AND METHODS: 100 prostates were acquired from consecutive radical prostatectomies performed by the same surgeon. Fourteen core
