Glioblastoma‐activated pericytes support tumor growth via immunosuppression
Cancer Medicine, Volume 7, Issue 4, Page 1232-1239, April 2018., 2018 Glioblastoma‐activated pericytes develop an immunosuppressive phenotype, reducing T‐cell activation through the induction of an anti‐inflammatory response. Pericytes support glioblastoma growth in vitro and in vivo. Abstract Glioblastoma multiforme is the most common and aggressive primary brain tumor, with an extremely poor prognosis.

Bacterioplankton Activity in a Meso‐eutrophic Subtropical Coastal Lagoon
International Journal of Microbiology, Volume 2018, Issue 1, 2018., 2018 The aim of this study was to investigate whether the bacterioplankton activity in the meso‐eutrophic Conceição Lagoon would increase significantly under allochthonous inputs of inorganic nutrients and organic carbon. Abundance and biomass of bacterioplankton were evaluated under three treatments: light (14 h light/10 h dark), complete darkness (dark ...

Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems
Global Ecology and Biogeography, Volume 35, Issue 7, July 2026.ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...

Evaluation of Hemagglutination Activity of Chitosan Nanoparticles Using Human Erythrocytes
BioMed Research International, Volume 2015, Issue 1, 2015., 2015 Chitosan is a polysaccharide composed of randomly distributed chains of β‐(1‐4) D‐glucosamine and N‐acetyl‐D‐glucosamine. This compound is obtained by partial or total deacetylation of chitin in acidic solution. The chitosan‐based hemostatic agents have been gaining much attention in the management of bleeding.

Ecosphere, Volume 17, Issue 4, April 2026.Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015 The photocatalytic degradation of indigo carmine (IC) dye in the presence of titanium dioxide under different conditions was reported. Several factors which interfere with the photodegradation efficiency as catalyst concentration, pH, initial concentration of dye, presence of inorganic anions, temperature, and the addition of hydrogen peroxide were ...
