New topical microemulsions of etofenamate as sufficient management of osteoarthritis

Abstract In this study, microemulsions containing etofenamate were prepared and evaluated as dermal delivery carriers. The developed microemulsions consist of oleic acid, Span 80, Tween 20, Cremophor EL, Transcutol and ethanol. The percentage of etofenamate loading in the microemulsions was 5% (w/w). The...

Relationship between PI3K/mTOR/RhoA pathway-regulated cytoskeletal rearrangements and phagocytic capacity of macrophages

Braz. j. med. biol. res; 53 (7), 2020
The objective of this study was to investigate the relationship between PI3K/mTOR/RhoA signaling regulated cytoskeletal rearrangements and phagocytic capacity of macrophages. RAW264.7 macrophages were divided into four groups; blank control, negative control, PI3K-RNAi, and mTOR-RNAi. The cytoskeletal ch...

Perillyl alcohol has antibacterial effects and reduces ROS production in macrophages

J. appl. oral sci; 28 (), 2020
Abstract Natural products have emerged as a rich source of bioactive compounds for adjunctive treatments of many infectious and inflammatory conditions, including periodontitis. Among the monoterpenes with significant biological properties, there is the perillyl alcohol (POH), which can be found in sever...

In vitro evaluation of Eugenia dysenterica in primary culture of human gingival fibroblast cells

Abstract: Eugenia dysenterica is a Brazilian tree investigated for its properties and bioactive compounds, which are believed to have both pharmacological and phytochemical therapeutic effects. The leaves of this tree contain tannins, flavonoids, terpenes, and saponins, with reportedly beneficial effects...

Colecalciferol regula os parâmetros hematológicos e a produção de citocinas pró-inflamatórias renais em camundongos diabéticos e nas células RAW 264. 7

Os efeitos causados pelo tratamento em conjunto da insulina e do colecalciferol em indivíduos diabéticos não estão completamente elucidados. O presente trabalho avaliou o efeito de ambos os hormônios nos rins, no fígado, no coração e nos parâmetros hematológicos de camundongos machos (C57BL/6) ...

Inhibitory effects on the production of inflammatory mediators and reactive oxygen species by Mori folium in lipopolysaccharide-stimulated macrophages and zebrafish

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT Mori folium, the leaf of Morus alba L. (Moraceae), has been traditionally used for various medicinal purposes from ancient times to the present. In this study, we examined the effects of water extract of Mori folium (WEMF) on the production of inflammatory mediators, such as nitric oxide (NO) an...

Metabotropic glutamate receptor 5 may be involved in macrophage plasticity

Biol. Res; 50 (), 2017
Abstract Background Macrophages are a functionally heterogeneous cell population and depending on microenvironments they polarize in two main groups: M1 and M2. Glutamic acid and glutamate receptors may participate in the regulation of macrophage plasticity. To investigate the role of glutamatergic sys...

Differential roles for pathogenicity islands SPI-13 and SPI-8 in the interaction of Salmonella Enteritidis and Salmonella Typhi with murine and human macrophages

Biol. Res; 50 (), 2017
BACKGROUND: Salmonella pathogenicity island (SPI)-13 is conserved in many serovars of S. enterica, including S. Enteritidis, S. Typhimurium and S. Gallinarum. However, it is absent in typhoid serovars such as S. Typhi and Paratyphi A, which carry SPI-8 at the same genomic location. Because the interactio...
