Estudo das vesículas extracelulares de Toxoplasma gondii e a correlação com o sistema imune de hospedeiros infectados

As vesículas extracelulares (EVs) são nanopartículas produzidas e liberadas por células eucarióticas e procarióticas com propriedades biológicas. EVs desempenham um papel importante no sistema imunológico, transporte de moléculas e comunicação celular. A fim de compreender a participação das...

Identification of new human mesenchymal stem cell biomarker by aptamers

Stem cells are undifferentiated cells that can be distinguished from others by their ability to self-renew and to differentiate into new specific cell types. Mesenchymal stem cells (MSC) are adult stem cells that can be obtained from different sources, such as adipose tissue, bone marrow, dental pulp, an...

Perfil inflamatório e microbiológico de pacientes com infecção endodôntica primária e periodontite apical: estudo observacional

O objetivo deste estudo foi avaliar o perfil microbiológico e identificar padrões de agregação bacteriana, avaliar a associação desses padrões com os níveis de mediadores inflamatórios, MMPs e sinais e sintomas clínicos e ainda correlacionar os mediadores inflamatórios entre si e com os sinais...

Wound-healing and cytokine-modulating potential of medicinal oil formulation comprising leaf extract of Murraya koenigii and olive oil

Braz. j. biol; 82 (), 2022
The study investigated the wound healing effect of medicinal oil (MO) formulation prepared from Murraya koenigii leaves extract (methanolic) incorporated in olive oil. The MO was visually transparent, homogenous, smooth in texture, the viscosity grade was observed as 140 cP and easily spreadable. Pro-inf...

Abstract Objective: To compare the Oncostatin M (OSM) concentrations in tissues of patients with chronic periodontitis with and without diabetes. Material and Methods: Sixty-four subjects visiting the dental outpatient department were categorized as "healthy" (Group 1), "periodontitis" (Group 2), and "...

Detection of respiratory viruses and expression of inflammatory cytokines in patients with acute exacerbation chronic obstructive pulmonary disease in Mongolia China

Braz. j. biol; 82 (), 2022
Chronic obstructive pulmonary disease (COPD) was estimated to be the third cause of global mortality by 2020. Acute exacerbation COPD (AECOPD) is a sudden worsening of COPD symptoms and could be due to virus/bacterial infections and air pollution. Increased expression of inflammatory markers in patients ...

Acute effects of different intensities resistance training on inflammatory markers of women with severe obesity

ABSTRACT This study objective to compare the acute effects between one resistance training bout with high versus moderate intensities on inflammatory markers in women with severe obesity. Experimental crossover study, performed with adult women with severe obesity (BMI ≥ 40.0 kg/m²; age ≥ 18...

Avaliação da carga microbiana e fúngica de sistemas de canais radiculares infectados e a expressão apical de integrinas, citocinas e quimiocinas nos tecidos

Este estudo busca avaliar quantitativamente a expressão do RNA mensageiro (mRNA) das integrinas alfa1, alfa4, alfa 5, alfa L, citocinas e quimiocinas, a partir de células presentes no líquido intersticial periapical adjacente a dentes com infecção do canal radicular. Foram selecionados 22 indivíduo...

Differential Regulation of Integrin α5 and β4 in Normal and Psoriatic Epidermal Keratinocytes

Abstract Psoriasis is a chronic skin inflammation, characterized by impaired differentiation, hyperproliferation of keratinocytes involving pro-inflammatory factors interleukin (IL)-13/17A, tumor necrosis factor (TNF)-α, interferon (IFN)-γ. Among the integrin family, α5 is important for blood vessel ...

La inflamación como el nexo entre la enfermedad periodontal y la enfermedad cardiovascular
Inflammation as a link between periodontal disease and cardiovascular disease

La periodontitis es una enfermedad no transmisible, con una alta prevalencia, que oscila entre el 45% y el 50% de la población mundial, ocupando el sexto lugar entre las enfermedades más frecuentes de la huma-nidad. Existe suficiente evidencia que avala la relación entre la enfermedad periodontal y la...
