Probable Association Between Oral Lichen Planus and presence of Helicobacter Pylori: a Preliminary Study in a Chilean Population

ABSTRACT: Oral Lichen planus (OLP) is one of the main inflammatory diseases of the oral mucosa that is considered as a potentially malignant disorder. The exact pathogenesis of OLP remains to be completely understood. However, presence of bacteria has been associated to the inflammatory response observed...

Objetivo: Determinar los mecanismos de resistencia antibiótica y la epidemiología molecular de aislados clínicos de Klebsiella pneumoniae resistentes a carbapenémicos. Materiales y métodos: 30 aislados multirresistentes de K. pneumoniae fueron obtenidos a partir de: urocultivo, aspirado traqueal,...

Fuente de alimentación de ejemplares de Triatoma sordida en un área con alto riesgo de domiciliación en el Chaco Paraguayo

En el presente estudio evaluamos indicadores entomológicos (índices de infección, colonización e infección natural) de ejemplares de Triatoma sordida capturados en el intra y peridomicilio de viviendas del Chaco Paraguayo en el período 2014 al 2016. El objetivo fue comparar con los hallazgos previa...

Outcomes of long term treatments of type I hereditary angioedema in a Turkish family

An. bras. dermatol; 92 (5), 2017
Abstract: Background: Hereditary angioedema is a rare autosomal dominantly inherited immunodeficiency disorder characterized by potentially life-threatening angioedema attacks. Objective: We aimed to investigate the clinical and genetic features of a family with angioedema attacks. Methods: The medica...

Selection of suitable reference genes for abiotic stress-responsive gene expression studies in peanut by real-time quantitative PCR

Background: Because of its strong specificity and high accuracy, real-time quantitative PCR (RT-qPCR) has been a widely used method to study the expression of genes responsive to stress. It is crucial to have a suitable set of reference genes to normalize target gene expression in peanut under different ...

Higher prevalence and gene amplification of HPV16 in oropharynx as compared to oral cavity

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective The objective of this study was to clarify differences regarding HPV16 infection and gene amplification between the oral cavity and oropharynx in healthy individuals. Material and Methods The subjects were 94 healthy asymptomatic individuals (41 males, 53 females; mean age 58.6 yea...

Utility of multiplex real-time PCR in the diagnosis of extrapulmonary tuberculosis

Braz. j. infect. dis; 20 (3), 2016
Abstract Objective The diagnosis of extrapulmonary tuberculosis is still a challenge because of its pauci-bacillary nature. The aim of the study was to evaluate the role of a multiplex PCR assay in the diagnosis of extrapulmonary tuberculosis and to compare the efficiency of two targets, IS6110 and MPB6...

Cloning, expression and characterization of the endoglucanase gene from Bacillus subtilis UMC7 isolated from the gut of the indigenous termite Macrotermes malaccensis in Escherichia coli

Electron. j. biotechnol; 18 (2), 2015
Background Bacillus subtilis UMC7 isolated from the gut of termite Macrotermes malaccensis has the ability to secrete a significant amount of extracellular endoglucanase, with an enzyme activity of 0.12 ± 0.01 μmol/min/mL. However, for economically viable industrial applications, the enzyme needs t...

Gene amplification in Rhynchosciara (1955-1987)

Mem. Inst. Oswaldo Cruz; 82 (supl.3), 1987
A review is made of the evidence indicating the existence of gene amplification in Rhynchosciara, from the early cytological work to the more recent studies using cloned sequences from the DNA puffs. Mention is made of work still in progress which indicates that the transcription unit of a DNA puff is su...
