NOAC versus AVK: avaliação da qualidade de vida em idosos com fibrilhação auric...

Introdução: A Fibrilhação Auricular (FA) é uma importante causa de morbimortalidade na população idosa. Os anticoagulantes orais assumem-se como eficazes na prevenção do Acidente Vascular Cerebral cardioembólico. Não existe evidência científica que suporte a decisão de escolha entre antagonistas da vitamina K (AVK) e novos anticoagulantes orais (NOAC), baseado no critério qualidade de vida.Objetivo: Avaliar a q...

Sleep and Media Screens in Pediatric Ages

Introduction: Sleep plays an essential role in children’s physical, emotional and behavioral health. Understanding the sleep architecture, sleep duration requirements as well as the interference of media screens activity with sleep across pediatric ages is essential in order to provide an adequate anticipatory guidance for the children’s parents. Objectives: To review current knowledge on sleep physiology with ...

Dormancy within Staphylococcus epidermidis biofilms : a transcriptomic analysis...

The proportion of dormant bacteria within Staphylococcus epidermidis biofilms may determine its inflammatory profile. Previously, we have shown that S. epidermidis biofilms with higher proportions of dormant bacteria have reduced activation of murine macrophages. RNA-sequencing was used to identify the major transcriptomic differences between S. epidermidis biofilms with different proportions of dormant bacteri...

Staphylococcus epidermidis biofilms with higher proportions of dormant bacteria...

Staphylococcus epidermidis is an opportunistic pathogen due to its ability to establish biofilms on indwelling medical devices. The presence of high amounts of dormant bacteria is a hallmark of biofilms, making them more tolerant to antimicrobials and to the host immune response. We observed that S. epidermidis biofilms grown in excess glucose accumulated high amounts of viable but non-culturable (VBNC) bacteri...

Modulation of poly-N-acetylglucosamine accumulation within mature Staphylococcu...

PNAG is a major component of Staphylococcus epidermidis biofilms involved in intercellular adhesion as well as in the interaction of the biofilm with components of the host immune response. Synthesis of PNAG has been found to be regulated by several environmental factors. In the present study, the effect of glucose metabolism-dependent culture medium acidification in PNAG accumulation was evaluated. Established...

SYBR green as a fluorescent probe to evaluate the biofilm physiological state o...

Staphylococcus epidermidis biofilms with different proportions of viable but nonculturable bacteria were used to show that SYBR green (SYBR) may be used as a probe to evaluate the bacterial physiological state using flow cytometry. Biofilms grown in excess glucose presented significantly higher proportions of dormant bacteria than biofilms grown in excess glucose with buffered pH conditions or with exponential-...

The presence of high amounts of dormant bacteria is a hallmark of biofilms, making them more tolerant to antimicrobials and to the host immune response.

Plasmacytoid and conventional dendritic cells are early producers of IL-12 in N...

Neospora caninum is a coccidian parasite causative of clinical infections in a wide range of animal hosts. The maturation and activation of splenic conventional dendritic cells (cDCs) and plasmacytoid dendritic cells (pDCs) were studied here in BALB/c mice challenged intraperitoneal with N. caninum tachyzoites. The number of cDCs was found to decrease in the spleen of the infected mice 12 h and 2 days after the...

Extracellular matrix in Staphylococcus epidermidis biofilms: a consequence of b...

Staphylococcus epidermidis is a leading pathogen accounting for nosocomial infections. The ability to form biofilms is considered the major virulence factor of this bacterium. The hallmark of this type of infection is the presence of an extracellular polymeric matrix that, in the case of S. epidermidis biofilms, is mainly constituted by an N-acetylglucosamine polymer. We have identified a subpopulation of bacte...
