1. Unusual presentation of a disseminated oral HPV infection after combined antiretroviral therapy initiation
ABSTRACT HPV clinical manifestations have their characteristics modified by the use of combined antiretroviral therapy (cART), although its incidence is unaffected by cART. We report an unusual presentation of oral HPV infection and discuss an effective treatment for disseminated HPV lesions. A 52-year-old male of Asian-origin, HIV-seropositive, presented wi

2. DEVELOPMENT OF A NEW PROCESS FOR PURIFICATION OF CAPSULAR POLYSACCHARIDE FROM Streptococcus pneumoniae SEROTYPE 14
Abstract The main virulence factor of Streptococcus pneumoniae is the capsular polysaccharide (PS), which is the antigen of all current vaccines that are prepared with PS purified from serotypes prevalent in the population. In this work, three purification strategies were evaluated and a new process was developed for purification of serotype 14 PS (PS14), re

3. Assessment of the effectiveness of the PPD-mallein produced in Brazil for diagnosing glanders in mules
To assess the potency of the PPD-mallein produced in Brazil, five animals were from a property identified as a focus of glanders. These animals had suggestive clinical signs of the disease and the other five, from a property free from glanders, showed no clinical signs and were serology negative (control group). PPD-mallein from Burkholderia mallei was obtai

4. Ablação endometrial com ácido tricloroacético em ratas: estudo histomorfométrico e histológico / Endometrial ablation using trichloroacetic acid in rat model: histomorphometric and histologic evaluation
INTRODUCTION: Dysfunctional uterine bleeding is one of the most prevalent causes of uterine bleeding and it is related to hormonal variations without organic causes. Endometrial ablation is a therapeutic option but the methods are frequently expensive and dependent of high cost technologies. The objective of the present study is to develop an animal model of

5. DETERMINAÇÃO DE ÁCIDOS HALOACÉTICOS EM ÁGUA UTILIZANDO TÉCNICAS CROMATOGRÁFICAS / DETERMINATION OF ACIDS IN HALOACÉTICOS WATER USING CHROMATOGRAPHIC TECHNIQUES
Disinfection is an essential step in water treatment. This step, in most cases, is made by the use of chlorine and its derivatives, which have been quite effective. However, the use of chlorination to disinfect water produces various organic substances, among them, haloacetic acids (HAAs), a total of nine species: monochloroacetic acid (MCAA), dichloroacetic

6. Screening for antimicrobial activity among bacteria isolated from the amazon basin
Bacteria producing antimicrobial activity were identified among 86 isolates from aquatic environments of Brazilian Amazon Basin. Antimicrobial activity against at least one indicator strain was detected for 59 isolates (68.6%). Inhibitory activity was mostly against Gram-positive bacteria, such as Listeria monocytogenes and Bacillus cereus. The antimicrobial

7. Perfil protéico de sementes de acessos de cacaueiro no desenvolvimento do sabor de chocolate / Proteic profile from different accessions of cocoa seeds on the chocolate flavor development
Typical chocolate flavor is unique, only obtained from fermented, dried and roasted cocoa seeds, and can not be synthesized artificially. The flavor development is influenced by the genetic constitution, post-harvest processing and manufactures. Cotyledons proteins are believed to be the precursors of the chocolate flavor. The aim of the present work was to

11. Influência de desproteinizantes ácidos na quantificação da glutationa reduzida eritrocitária por CLAE-UV
Large differences in reduced glutathione (GSH) levels have been found in different investigations, also in healthy people. GSH oxidation in vitro has been associated with sample acidification in the presence of oxihemoglobin. In this work, the influence of different acids on GSH determination utilizing HPLC with UV detection was evaluated. The results showed
