SBTX has in vitro activity against phytopathogenic fungi such as Cercospora sojina, Aspergillus niger, and Penicillium herguei, and yeasts like Candida albicans, C. parapsilosis, Kluyveromyces marxiannus, and Pichia membranifaciens. The present study aimed to analyze in vitro whether SBTX causes any side effects on non-target bacterial and mammalian cells that could impede its potential use as a novel antifungal agent. SBTX at 100 μg/ mL and 200 μg/mL did not hinder the growth of the bacteria Salmonella enterica (subspecies enterica serovar choleraesuis), Bacillus subtilis (subspecies spizizenii) and Staphylococcus aureus. Moreover, SBTX at concentrations up to 500 μg/mL did not significantly affect the viability of erythrocytes, neutrophils, and human intestinal Caco-2 cells. To study whether SBTX could induce relevant alterations in gene expression, in vitro DNA microarray experiments were conducted in which differentiated Caco-2 cells were exposed for 24 h to 100 μg/mL or 200 μg/mL SBTX. SBTX up-regulated genes involved in cell cycle and immune response pathways, but downregulated genes that play a role in cholesterol biosynthesis and platelet degranulation pathways. Thus, although SBTX did not affect bacteria, nor induced cytotoxity in mammalian cells, it affected some biological pathways in the human Caco-2 cell line that warrants further investigation.

Cancer patients are in risk for severe disease, including a higher risk of intensive care unit (ICU) admission, need for invasive ventilation or death. Management of patients with lymphoid malignancies can be challenging during the outbreak, due to need of multiple hospital visits and admissions, immunosuppression and need for chemotherapy, radiotherapy and stem cell transplantation. In this article, we will focus on the practical management of patients with lymphoid malignancies during the COVID-19 pandemic, focusing on minimizing the risk for patients.

(Polygonaceae family) is a plant species from Brazilian semiarid region which is used in local traditional medicine for the treatment of inflammatory conditions such as hemorrhoids. AIM OF THE STUDY In this study, the in vitro anti-inflammatory activity of different concentrations of ethanolic extract from T. gardneriana seeds (EETg) was performed in order to contribute to the knowledge about etnomedicinal use of this plant species. MATERIALS AND METHODS The anti-inflammatory properties were evaluated through different approaches, such as in vitro protein anti-denaturation test, scavenging of reactive oxygen species (ROS) and myeloperoxidase (MPO) inhibition in human neutrophils activated by phorbol-12-myristate-13-acetate (PMA). Besides that, molecular docking was performed to provide new insights about the interaction between the major phenolic components in the plant extract and MPO. RESULTS EETg was characterized showing a total phenol content of 153.5 ± 6.3 μg gallic acid equivalent/mg extract, ability to remove hydrogen peroxide (H2O2) in a concentration-dependent manner and had a spectroscopic profile which suggests the presence of hydroxyl groups. EETg was able to prevent protein denaturation ranging from 40.17 to 75.09%. The extract at 10 and 20 μg/mL, was able to modulate neutrophils pro-inflammatory functions, such as degranulation and burst respiratory. In both assays, the EETg had anti-inflammatory effect comparable to nonsteroidal anti-inflammatory drugs. Among the main phenolic compounds of EETg, quercitrin, quercetin and catechin showed the highest binding affinity in silico to MPO. CONCLUSION This study demonstrated, for the first time, that the anti-inflammatory effect of T. gardneriana seeds occurs due to its modulatory effect on human neutrophil degranulation and free-radical scavenging activity.

The chimeric drug brentuximab vedotin that combines an anti-CD30 monoclonal antibody with the anti-tubulin agent monomethyl auristatin E demonstrated activity in patients with relapsed CHL, ALCL and other lymphomas that express CD30+. Previous observational studies have suggested that CD30 may be expressed in 10 to 20% of DLBCLs. It is possible that CD30+ DLBCLs may show different biologic behavior and be amenable to anti-CD30 therapy. The aim of this study was to determine the prevalence of CD30 expression in DLBCL by immunohistochemistry and explore possible relationships with important clinical and biologic variables of DLBCL. Methods: We retrospectively identified cases of DLBCL diagnosed between Jan 2007 and march 2014 at our institution. Eligible cases included patients with diagnosis of DLBCL irrespective of anatomic site or tumor stage....

(Pequi) is found in southern Ceará, where the fruit is used as food and in folk medicine as an anti-inflammatory, and to promote healing. However, little is known about the effects of repeated administration of its oil on the biochemical parameters of the blood. This work aimed to evaluate the effects Caryocar coriaceum fixed oil (OFCC); on the lipid profiles of healthy mice, on dyslipidemia induced by tyloxapol, and to study its anti-inflammatory effect both in vivo and in vitro. The results revealed significate reduction in total serum cholesterol and triglycerides, and an increase in HDL-C. The paw edema (induced by carrageenan) and myeloperoxidase (MPO), in polymorphonuclear culture cells, was reduced at all dose levels.

Este artigo analisa as falas de informantes-chave sobre as realizações dos Congressos. São 13 entrevistas com presidentes da Abrasco e coordenadores das Comissões de Ciências Sociais, em diferentes gestões – anos de realização dos Congressos Brasileiros de Ciências Sociais e Humanas em Saúde, entre 1995 e 2011.
