Paracoccidioides brasiliensis is a facultative, intracellular pathogen causing the most important deep mycosis in Latin America. As the production of IFN-γ and induction of cell-mediated immunity to P. brasiliensis is of critical importance in host defense, the immunotherapeutic effect of exogenous IL-12 administration was studied in a murine model of susceptibility to pulmonary infection. rIL-12 treatment led to a less disseminated disease, as confirmed by decreased fungal loads in liver and spleen. ...

Abstract Background Native bees of the tribe Meliponini produce a distinct kind of propolis called geopropolis. Although many pharmacological activities of propolis have already been demonstrated, little is known about geopropolis, particularly regarding its antimicrobial activity against oral pathogens. The present study aimed at investigating the antimicrobial activity of M. fasciculata geopropolis against oral pathogens, its effects on S. mutans biofilms, and the chemical contents of the extracts. ...

The propolis of Scaptotrigona aff. postica is popularly used in Maranhão State, Brazil, for treating wounds and respiratory illnesses. Nevertheless, little is known about the chemical composition of this propolis and the adverse effects of its use. Hence, this study is a pharmacognostic characterisation of the propolis hydroalcoholic extract (PHE) from S. aff. postica. The methodology consisted of an evaluation of the sensory and chemical parameters. Chemical analysis of PHE indicated high concentrations ...

Introduction The aim of this study was to isolate and grow cells from sound human deciduous teeth pulp with different levels of resorption and evaluate stem cell parameters. Methods Pulp tissue was removed from 30 different patients, aged from 6 to 12 years. From all the teeth, 21 were in advanced levels of resorption (group 1), and the remaining nine teeth did not show any visible resorption (group 2). Pulp tissue was removed and dissociated, and the suspension was seeded onto 12-well plates. The ...

The aqueous extract of a Brazilian palm-tree fruit - the babassu - (BAE) exerts a clear immunostimulative activity in vivo. In the present work, the possibility that BAE can promote Th1 immune responses in mice of a Th2 immune response-prone strain - the BALB/c was investigated. BAE itself, and preparations consisting of Leishmania amazonensis promastigote extract (LE), adsorbed or not to Al(OH)3, and in the presence or not of BAE, were used as immunogens. LE and Al(OH)3 have been shown to preferentially ...

Despite several studies showed that the Tityus serrulatus scorpion venom (Tsv) induces an inflammatory response, just a few have investigated the effect of the venom on the immune response. Therefore, the aim of this study was to evaluate alterations of venom application on lymphoid organs and on the recruitment and activation of cells and also on the cytokine production. Swiss male mice (2–3 months, 20–25 g) received a non-lethal dose of crude Tsv (200 μg/kg), diluted in sterile PBS by subcutaneous ...

The tumoricidal activity of activated macrophages has been attributed largely to the release of tumor necrosis factor (TNF), or to the production of reactive oxygen or nitrogen intermediates. The L929 tumor cell line (a murine fibroblast-like cell) when treated with actinomycin D (ActD) has been used to measure TNF a cytotoxicity. In the present study, we determined the cytotoxic activity of BCG-activated peritoneal macrophages against ActD-untreated L929 tumor cells. Furthermore, we measured the production ...

Macrophages are important components of natural immunity involved in inhibition of tumor growth and destruction of tumor cells. It is known that these cells can be activated for tumoricidal activity by lymphokines and bacterial products. We investigated whether YAC-1 tumor cells infected with Mycoplasma arginini stimulate nitric oxide (NO) release and macrophage cytotoxic activity. Thioglycollate-elicited macrophages from male BALB/c mice were co-cultured for 20 h with YAC-1 tumor cells infected ...

Propolis is a resinous substance made by bees. It possesses many biological activities, and many studies have reported its potential application in the control of dental caries. However, variability in the chemical composition of propolis is a potential problem in its quality control, especially since propolis has already been incorporated into products for oral use. Therefore, a critical analysis of the available data on propolis is warranted. The present review discusses the in vitro and in vivo ...

Abstract Using a murine model of susceptibility and resistance to paracoccidioidomycosis, we have previously demonstrated that immunosuppression occurs in susceptible (B10.A), but not in resistant (A/Sn), mouse strains. Accumulating evidence shows that NO is involved in the induction of T cell immunosuppression during infection as well as in the killing of Paracoccidioides brasiliensis. In the present work, we focused on NO and other macrophage products that could be associated with resistance or ...

It has been shown experimentally that sheath folds can develop passively by kinematic amplification of precursor non-cylindrical deflections. However, sheath folds are most commonly multilayers where rheological contrast can be expected (non-passive sheath folding). Therefore, we studied a natural occurrence of sheath folds where layers show rheological contrast and used analogue modelling to investigate sheath fold development with viscosity contrast (μ′). The initial deflection in the experiments ...
