The vasodilator/antiproliferative peptide angiotensin-(1-7) [ANG-(1-7)] is released into the corpus cavernosum sinuses, but its role in erectile function has yet to be defined. In this study, we sought determine whether ANG-(1-7) and receptor Mas play a function. was immunolocalized rat by confocal microscopy. Infusion of at rate 15.5 pmol x kg(-1) min(-1) potentiated elevation pressure induced electrical stimulation major pelvic ganglion (MPG) rats. facilitatory effect completely blunted...
OBJECT The development of neurointerventional treatments central nervous system disorders has resulted in the need for adequate training environments novice interventionalists. Virtual simulators offer anatomical definition but lack tactile feedback. Animal models, which provide more lifelike training, require an appropriate infrastructure base. authors describe a model procedures using human placenta (HP), affords haptic with significantly fewer resource requirements, and discuss its...
Human spermatogonial stem cells (SSCs) are an essential source to maintain spermatogenesis as efficient process for daily sperm production with high self-renewal capacity along adulthood. However, the phenotype and subpopulation that represent real reserve SSC human testis remain unknown. Moreover, although markers have been described undifferentiated spermatogonia (Adark Apale), existence of a specific subtype could be identified actual/true has not yet fully determined. Herein we evaluated...
Can all types of testicular germ cells be accurately identified by microscopy techniques and unambiguously distributed in stages the human seminiferous epithelium cycle (SEC)?By using a high-resolution light (HRLM) method, which enables an improved visualization cell morphological features, we precisely grouped them six well-delimitated SEC stages, thus providing reliable reference source for staging man.Morphological characterization has been done decades ago with use conventional...
BACKGROUND: Brain tumors are complex 3-dimensional lesions. Their resection involves training and the use of multiple microsurgical techniques available for removal. Simulation models, with haptic visual realism, may be useful improving bimanual technical skills neurosurgical residents neurosurgeons, potentially decreasing surgical errors thus patient outcomes. OBJECTIVE: To describe assess an ex vivo placental model brain tumor microsurgery using a simulation tool in psychomotor teaching...
The rate of motile sperm recovery after cryopreservation is very variable and difficult to predict. Anti-Müllerian hormone (AMH) inhibin B are produced by Sertoli cells released into the seminal plasma, where they could be functional markers spermatogenesis resistance thermal stress. aim this study was evaluate whether plasma levels AMH predict cryopreservation. included 153 men enrolled prospectively during a semen analysis. cohort stratified fresh characteristics into: normal (n = 52),...
Abstract The present study aimed to analyze factors associated with access of dental care services by Brazilian hemodialysis patients. A cross-sectional was carried out 467 patients aging from 19 90 years in two renal therapy centers located the cities Contagem and Belo Horizonte, Southeastern Brazil. Data were collected through an oral clinical examination application a structured questionnaire. dependent variable care, measured question "Have you consulted dentist last six months?". mean...
Purpose: To develop and validate a new test of specific technical skills required for microsurgical varicocelectomy. Materials Methods: An electronic questionnaire was sent to 558 members the Brazilian Society Urology validation task-specific checklist (TSC) assessment Participants who had experience in this procedure were selected as judges. For construct validation, 12 participants including attending urologists urological residents training recruited voluntary participation. We formed...
Coagulant fixatives and paraffin embedding were widely used in the past for histomorphometrical evaluations of human testis under physiological pathological conditions. However, new methods are applied nowadays using better combinations plastic resins as media, improving cell tissue structural preservation. In an attempt to compare old data, present study evaluated data obtained from after three different histological processing methods: Bouin/paraplast, glutaraldehyde/glycol methacrylate...
SUMMARY BACKGROUND The aim of this study was to perform a cross-cultural adaptation the Objective Structured Assessment Technical Skill (OSATS) tool into Brazilian Portuguese and determine its reproducibility validity in Brasil. METHODS A version OSATS created through process translation, back-translation, expert panel evaluation, pilot testing, then validation. For construct concurrent validities, twelve participants were divided group six experts novices, who had tasks on simulation model...
Spermatogenesis is under the control of a complex endocrine and paracrine system, including estrogen receptor (ER) signaling. In many target cells, ER promotes transcription c-fos other proto-oncogenes to regulate cell growth differentiation. Thus, in this study we evaluated expression proto-oncogene immunolocalization c-fos, phosphorylated ERbeta proteins human testis. Testis tissue samples were obtained from 12 men undergoing orchiectomy as adjuvant treatment for prostate cancer, stained...
The present study was designed to evaluate whether tissue preparation by glutaraldehyde and glycol methacrylate (G/GMA) improves the diagnostic assessment of testicular biopsies from azoospermic men when compared standard using Bouin's solution paraffin. We prospectively included a total 21 sexually mature aged 29-50 years with infertility azoospermia. One biopsy fragment each patient processed G/GMA method, whereas another contemporarily conventional Bouin/paraffin (B/P) method. method...
Introduction: Prostatic cysts are rare lesions that may cause compression of the ejaculatory ducts resulting in azoospermia.1 Transrectal ultrasound (TRUS) identify midline be acquired or congenital.2,3 Transurethral resection (TURED) an effective treatment for obstructive azoospermic infertile men.4,5 The aim this study was to describe our experience with TRUS and TURED as diagnostic therapeutic tools management duct obstruction caused by prostatic causing male infertility. Methods: We...
