Detection and clearance of a mosquito densovirus contaminant from laboratory stocks of Zika virus

Mem. Inst. Oswaldo Cruz; 114 (), 2019
BACKGROUND The Zika virus (ZIKV) epidemics that affected South America in 2016 raised several research questions and prompted an increase in studies in the field. The transient and low viraemia observed in the course of ZIKV infection is a challenge for viral isolation from patient serum, which leads to...

Brazilian spotted fever serological survey among equids at the Guarapiranga Dam area in the city of São Paulo, Brazil

In the Guarapiranga dam region located in the metropolitan area of São Paulo, human cases have been reported of Brazilian spotted fever (BSF), a tick-borne disease caused by the bacterium Rickettsia rickettsii. In this area, R. rickettsii is known to be transmitted to humans by Amblyomma aureolatum, a t...

Long non-coding RNA MALAT1 enhances the apoptosis of cardiomyocytes through autophagy inhibition by regulating TSC2-mTOR signaling

Biol. Res; 52 (), 2019
BACKGROUND: Our previous study showed that knockdown of long noncoding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) attenuated myocardial apoptosis in mouse acute myocardial infarction (AMI). This study aims to explore whether MALAT1 enhanced cardiomyocyte apoptosis via au...

Gliclazide reduced oxidative stress, inflammation, and bone loss in an experimental periodontal disease model

J. appl. oral sci; 27 (), 2019
Abstract Objective The aim of this study was to evaluate the effects of gliclazide on oxidative stress, inflammation, and bone loss in an experimental periodontal disease model. Material and Methods Male albino Wistar rats were divided into no ligature, ligature, and ligature with 1, 5, and 10 mg/kg ...

Avaliação das atividades anti-inflamatórias e antioxidantes da gliclazida em modelo experimental de mucosite oral induzida por 5-fluorouracil
Evaluation of the anti-inflammatory and antioxidant activities of gliclazide in an experimental model of oral mucositis induced by 5-fluorouracil

A mucosite oral (MO) é uma inflamação aguda da mucosa oral, sequela mais importante dos tratamentos de radioterapia ou/e quimioterapia. As lesões na cavidade oral são graves, dolorosas e podem levar a sepse e morte. Não existe um protocolo único de prevenção e cura para MO. Na perspectiva de enc...

Neuroprotective effects of an Nrf2 agonist on high glucose-induced damage in HT22 cells

Biol. Res; 52 (), 2019
BACKGROUND: Oxidative stress is the hallmark of diabetic encephalopathy, which may be caused by hyperglycaemic toxicity. We aimed to discover pharmacologic targets to restore redox homeostasis. We identified the transcription factor Nrf2 as such a target. METHODS: HT22 cells were cultured in 25 or 50 mM ...

Serological, molecular, and microscopic detection of Leishmania in cats (Felis catus) in Belo Horizonte, Minas Gerais State, Brazil

Abstract The role of cats in the epidemiological cycle of leishmaniasis remains unclear. To better understand the occurrence of leishmaniasis in cats, we studied the frequency of Leishmania in serum samples of 100 cats living in an endemic region for canine and human leishmaniasis by serological, parasi...

Morphological analysis of articularis genus and involvement in muscle synchronicity with vastus intermedius

Int. j. morphol; 36 (3), 2018
The articularis genus, which lies under the vastus intermedius, has been regarded as part of the quadriceps femoris. However, they are well known to have different function because their respective origins and insertions are mutually distinct. These muscles are considered to work almost simultaneously wh...

Vasculite urticariforme e exantema: uma reação de hipersensibilidade tardia mista a dimenidrinato – relato de caso

Relatamos um caso de uma mulher que após 14 dias de ter usado dimenidrinato, iniciou quadro de exantema e vasculite urticariforme, além de sintomas con...

The role of fetal-maternal microchimerism as a natural-born healer in integrity improvement of maternal damaged kidney

Int. braz. j. urol; 44 (3), 2018
ABSTRACT Purpose: To identify the fetal stem cell (FSC) response to maternal renal injury with emphasis on renal integrity improvement and Y chromosome detection in damaged maternal kidney. Materials and Methods: Eight non-green fluorescent protein (GFP) transgenic Sprague-Dawley rats were mated with G...
