1. Comparative study of four different types of intraperitoneal mesh prostheses in rats
Abstract Purpose: To compare four types of mesh regarding visceral adhesions, inflammatory response and incorporation. Methods: Sixty Wistar rats were divided into four groups, with different meshes implanted intraperitoneally: polytetrafluoroethylene (ePTFE group); polypropylene with polydioxanone and oxidized cellulose (PCD); polypropylene (PM) and polyp

2. 17,20β-P and cortisol are the main in vitro metabolites of 17-hydroxy-progesterone produced by spermiating testes of Micropogonias furnieri (Desmarest, 1823) (Perciformes: Sciaenidae)
The aim was to investigate the major C21 steroids produced by spermiating white croaker Micropogonias furnieri (Sciaenidae) in order to establish the potential mediator of gamete maturation in males of this species. The testes steroid production at the spawning season was identified incubating the 3H-17-hydroxy-4-pregnene-3,20-dione precursor through thin la

3. Triquilemocarcinoma e triquilemoma: estudo comparativo clínico, histopatológico e imunoistoquímico / Trichilemal carcinoma and trichilemmoma: a clinical, histopathological and immunochemical comparative study
Vários estudos têm relatado um aumento da incidência de câncer de pele em todo o mundo. No Brasil, o câncer de pele em geral continua sendo a neoplasia mais incidente em ambos os gêneros. Os tumores de anexos cutâneos compõem um grupo grande de neoplasias que exibem diferenciação morfológica para um dos epitélios anexiais da pele normal. Este tra

4. Acometimento hepático na paracoccidioidomicose em pacientes pediátricos : um estudo clínico, laboratorial e histológico = Hepatic involvement in pediatric patients with paràcoccidioidomycosis : a clinical, laboratory and hisptological study / Hepatic involvement in pediatric patients with paràcoccidioidomycosis : a clinical, laboratory and hisptological study
Paracoccidiodomycosis is a systemic mycosis, endemic in some countries of Latin America. The study aimed to describe the frequency, the clinical, laboratory and histological characteristics of liver involvement in children. The study has included 102 patients less than 16 years, treated between 1980 and 2010, with diagnosis confirmed by demonstration of the

5. PP65 antigenemia in the diagnosis of cytomegalovirus infection in AIDS patients
Cytomegalovirus causes significant morbidity and mortality in AIDS patients and those having undergone bone marrow or another transplant. PP65 antigenemia is based on detecting viral antigen in peripheral blood leukocytes through immunochemistry and by monitoring the infection in immunocompromised individuals. The present study aimed to set up this diagnosti

6. Langerhans cells in periodontal disease of HIV- and HIV+ patients undergoing highly active antiretroviral therapy
The aim of this study was to assess and compare quantitatively the presence of S100+ Langerhans cells (LC) by immunochemistry techniques in HIV+ and HIV- gingivitis and periodontitis subjects. Additionally, it aimed to evaluate the correlation among densities of these cells with CD4+ and CD8+ T cells, and viral load levels in HIV+ subjects, all using Highly

7. GM1 improves neurofascin155 association with lipid rafts and prevents rat brain myelin injury after hypoxia-ischemia
White matter injury characterized by damage to myelin is an important process in hypoxic-ischemic brain damage (HIBD). Because the oligodendrocyte-specific isoform of neurofascin, neurofascin 155 (NF155), and its association with lipid rafts are essential for the establishment and stabilization of the paranodal junction, which is required for tight interacti

9. Alterations of E-cadherin and β-catenin genes in pleomorphic adenoma and adenoid cystic carcinoma: molecular and immunohistochemical study / Alterações nos genes da E-caderina e β-catenina em adenoma pleomórfico e carcinoma adenóide cístico: estudo molecular e imuno-histoquímico
Pleomorphic adenoma and adenoid cystic carcinoma represent a benign and malignant salivary gland neoplasm, respectively, that shares the same histological origin, however with distinct biological behavior. The aim of the present study was identify the -160 C/A polymorphism in the gene CDH1, mutational analysis of CTNNB1 gene and evaluation the expression of

10. Ultrastructural description of rabies virus infection in cultured sensory neurons
Primary cultures were made from adult mouse spinal ganglia for depicting an ultrastructural description of rabies virus (RABV) infection in adult mouse sensory neuron cultures; they were infected with rabies virus for 24, 36, and 48 h. The monolayers were processed for transmission electron microscopy and immunochemistry studies at the end of each period. As

11. Evaluation of the acute oxidative stress after surgical trauma in the bone tissue of wistar rats. / Avaliação do estresse oxidativo agudo após trauma cirúrgico realizado em tecido ósseo de ratos wistar.
The purpose of this work was to evaluate the oxidative stress after surgical trauma, through the activation of the NF-kB (in vivo), in wistar rats, using immunohistochemistry method on non-demineralized tissue. The results indicate a similarity among the irrigated and adrenalectomized groups of implants. The group using dexamethasone and

12. Caracterização imunoquímica e molecular da fração dermonecrótica do veneno da aranha marrom Loxosceles intermedia
To investigate the biochemistry and the immunochemistry of proteins from L. intermedia spider venom, thirteen monoclonal antibodies were produced. On of them,called LimAb7, was able to neutralize the dermonecrotic activity induced by venom in rabbits. In an effort to characterize the proteins recognized by the neutralizing monoclonal antibody, we have used d
