3. Determination of phenolic profile by HPLC–ESI-MS/MS, antioxidant activity, in vitro cytotoxicity and anti-herpetic activity of propolis from the Brazilian native bee Melipona quadrifasciata
ABSTRACT Propolis is a rich source of bioactive molecules made by bees by collecting an infinite variety of secondary metabolites from plants. This study determined the chromatographic and mass spectrometry profile along with the biological activity of propolis produced by the native Brazilian bee Melipona quadrifasciata. A hydroalcoholic crude extract was p

4. Herpes simplex virus: isolation, cytopathological characterization and antiviral sensitivity
BACKGROUND:Herpes simplex virus (HSV) infection is an endemic disease and it is estimated that 6095% of the adult population are infected with symptoms that are usually self-limiting, though they can be serious, extensive and prolonged in immunocompromised individuals, highlighted by the emergence of drug-resistant strains. The study of the wild-type HSV str

5. Current status of herpesvirus identification in the oral cavity of HIV-infected children
INTRODUCTION: Some viruses of the Herpesviridae family are frequently the etiologic agents of oral lesions associated with HIV. The aim of this study was to identify the presence of herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Varicella Zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus type 6, type 7 and type

6. In vitro study of the effect of a probiotic bacterium Lactobacillus rhamnosus against herpes simplex virus type 1
BACKGROUND: Due to the emergence of drug resistance in herpes simplex virus type 1 (HSV-1), researchers are trying to find other methods for treating herpes simplex virus type 1 infections. Probiotic bacteria are effective in macrophage activation and may have antiviral activities. OBJECTIVE: This study aimed at verifying the direct effect of Lactobacillus r

8. Flexural strength of acrylic resin repairs processed by different methods: water bath, microwave energy and chemical polymerization
Denture fractures are common in daily practice, causing inconvenience to the patient and to the dentists. Denture repairs should have adequate strength, dimensional stability and color match, and should be easily and quickly performed as well as relatively inexpensive. OBJECTIVE: The aim of this study was to evaluate the flexural strength of acrylic resin re

9. Molecular detection of cytomegalovirus, herpes simplex virus 2, human papillomavirus 16-18 in Turkish pregnants
OBJECTIVE: Human cytomegalovirus (CMV) is the most common cause of viral intrauterine infections in the world. Herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) are the main agents of viral sexually transmitted diseases, which cause genital ulcers and genital warts, respectively. HPV infection has been linked to the majority of the anogenita

10. Técnicas computacionais para a implementação eficiente e estável de métodos tipo simplex / Computational techniques for an efficient and stable implemantation of simplex-type methods
Simplex-type methods are the basis of the main linear optimization solvers. The straightforward implementation of these methods as they are presented in theory yield unexpected results in solving reallife large-scale problems. Hence, it is essencial to use suitable computational techniques for an efficient and stable implementation. In this thesis, we addres
