Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats

Braz. j. med. biol. res; 49 (6), 2016
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in ...

Role of adenylyl cyclase in reduced β-adrenoceptor-mediated vasorelaxation during maturation

Braz. j. med. biol. res; 49 (7), 2016
Beta-adrenergic receptor (βAR)-dependent blood vessel relaxation is impaired in older animals and G protein activation has been suggested as the causative mechanism. Here, we investigated the role of βAR subtypes (β1AR, β2AR, and β3AR) and cAMP in maturation-dependent vasorelaxat...

Macelignan inhibits bee pathogenic fungi Ascophaera apis growth through HOG1 pathway

Braz. j. med. biol. res; 49 (7), 2016
Ascosphaera apis is a bee pathogen that causes bee larvae infection disease, to which treatment is not yet well investigated. The aim of this study was to investigate antifungal susceptibility in vitro against A. apis and to identify a new antifungal agent for this pathogen through minimal inhibitory con...

Effect of magnesium ion on human osteoblast activity

Braz. j. med. biol. res; 49 (7), 2016
Magnesium, a promising biodegradable metal, has been reported in several studies to increase bone formation. Although there is some information regarding the concentrations of magnesium ions that affect bone remodeling at a cellular level, little is known about the effect of magnesium ions on cell gap ju...

Galunisertib (LY2157299), a transforming growth factor-β receptor I kinase inhibitor, attenuates acute pancreatitis in rats

Braz. j. med. biol. res; 49 (9), 2016
Galunisertib (LY2157299), a selective ATP-mimetic inhibitor of TGF-β receptor I (TGF-βRI), is the only known TGF-β pathway inhibitor. In the present study, we investigated the effect of galunisertib on taurocholate (TAC)-induced acute pancreatitis (AP) in rats, and the role of TGF-β a...

Efectos in vivo del ranelato de estroncio sobre células progenitoras de médula ósea de ratas diabéticas
In vivo effects of strontium ranelate on bone marrow progenitor cells of diabetic rats

Actual. osteol; 12 (2), 2016
La diabetes mellitus (DM) crónica se asocia con reducción en el contenido mineral óseo (osteopenia y osteoporosis). El objetivo de este trabajo fue evaluar la acción del ranelato de estroncio (RaSr) administrado por vía oral a animales control y diabéticos, sobre el potencial osteogénico de célul...

Using agents that suppress bone remodeling to treat or prevent joint disease: quo vadis?

Actual. osteol; 12 (3), 2016
Treatment of osteoarthritis (OA) with antiremodeling agents has had a mixed record of results. It is likely that remodeling suppression is only effective when used in the early phases of OA, before significant progression. Animal and human studies largely bear this out. Treatment of young mice with a RAN...

Efectos de los corticoides inhalatorios sobre el crecimiento en niños con asma
Use of inhaled corticosteroids in children with asthma and effects on growth

Effect of EDTA on TGF-β1 released from the dentin matrix and its influence on dental pulp stem cell migration

Braz. oral res. (Online); 30 (1), 2016
Abstract: Bioactive molecules stored in dentin, such as transforming growth factor beta1 (TGF-b1), may be involved in the signaling events related to dental tissue repair. The authors conducted an in vitro evaluation of the amount of TGF-b1 released from dentin slices after treatment with 10% ethylenedia...

Antimicrobial activity of different disinfectants against cariogenic microorganisms

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to assess the in vitro antimicrobial effects of chlorhexidine digluconate (CHX), polyhexamethylene biguanide (PHBM), and octenidine dihydrochloride (OCT) on cariogenic microorganisms by using their minimum inhibitory concentration (MIC) and minimum bactericidal concentr...
