Extracellular HSP70 activates ERK1/2, NF-kB and pro-inflammatory gene transcription through binding with RAGE in A549 human lung cancer cells
(2017) [Artigo de periódico]Background/Aims: Heat shock protein 70 (HSP70) has been recently described with extracellular actions, where it is actively released in inflammatory conditions. Acting as DAMPs (damage associated molecular pattern) , ... -
Extracellular mycobacterial DnaK polarizes macrophages to the M2-like phenotype
(2014) [Artigo de periódico]Macrophages are myeloid cells that play an essential role in inflammation and host defense, regulating immune responses and maintaining tissue homeostasis. Depending on the microenvironment, macrophages can polarize to two ... -
Extracellular superoxide dismutase is necessary to maintain renal blood flow during sepsis development
(2017) [Artigo de periódico]Background: Extracellular superoxide dismutase (ECSOD) protects nitric oxide (NO) bioavailability by decreasing superoxide levels and preventing peroxynitrite generation, which is important in maintaining renal blood flow ... -
Extracting compound terms from domain corpora
(2010) [Artigo de periódico]The need for domain ontologies motivates the research on structured information extraction from texts. A foundational part of this process is the identification of domain relevant compound terms. This paper presents an ... -
Extracting parameters from colour–magnitude diagrams
(2015) [Artigo de periódico]We present a simple approach for obtaining robust values of astrophysical parameters from the observed colour–magnitude diagrams (CMDs) of star clusters. The basic inputs are the Hess diagram built with the photometric ... -
Extraction kinetics and molecular size fractionation of humic substances from two brazilian soils
(1999) [Artigo de periódico]No presente trabalho foi estudada sistematicamente a extração de substâncias húmicas (SH) de um Oxisol e de um Mollisol do Sul do Brazil, empregando-se soluções de NaOH 0.1 e 0.5 mol L-1 e de Na4P2O7 0.15 mol L-1 a pH 7. ... -
Extraction of poly(3-hydroxybutyrate) from Spirulina LEB 18 for developing nanofibers
(2015) [Artigo de periódico]The objective of this study was to extract poly(3-hydroxybutyrate) (PHB) from the microalgal biomass of Spirulina LEB 18 for the development of nanofibers by electrospinning method. Different extraction methods were tested. ... -
Extraction of soil water by plants : development and validation of a model
(1997) [Artigo de periódico]A quantitative model of water movement within the immediate vicinity of an individual root is developed and results of an experiment to validate the model are presented. The model is based on the assumption that the amount ... -
A extradição como instrumento de cooperação no Direito Penal Internacional
(2023) [Artigo de periódico]Neste artigo é realizada uma breve reflexão sobre a importância da extradição como instrumento de cooperação no âmbito do Direito Penal Internacional, com especial referência aos princípios da dupla incriminação e aut ... -

Extrapolação espacial na regionalização da vazão
(2003) [Artigo de periódico]A rede hidrológica brasileira foi instalada, principalmente, em grandes bacias hidrográficas. Os estudos de regionalização de vazão se baseiam nestes dados e, portanto podem apresentar incertezas para bacias com área de ... -
Extratores de fósforo para o arroz irrigado em solos adubados com fosfato natural reativo
(2012) [Artigo de periódico]Os fosfatos naturais reativos têm sido utilizados como fonte alternativa de fósforo (P) à cultura de arroz irrigado no estado do Rio Grande do Sul. O extrator Mehlich-1 é o método ofi cial de avaliação na disponibilidade ... -
Extreme and superextreme events in a loss-modulated CO2 laser : nonlinear resonance route and precursors
(2017) [Artigo de periódico]We investigate the occurrence of extreme and rare events, i.e., giant and rare light pulses, in a periodically modulated CO2 laser model. Due to nonlinear resonant processes, we show a scenario of interaction between chaotic ... -
Extreme galactic wind and Wolf-Rayet features in infrared mergers and infrared quasi-stellar objects
(2003) [Artigo de periódico]We report, as a part of a long-term study of infrared (IR) mergers and IR quasi-stellar objects (QSOs), detailed spectroscopic evidence for outflow (OF) and Wolf–Rayet (WR) features in the nearby mergers NGC4038/39 and ... -
Extreme homogeneity among brazilian wheat genotypes determined by RAPD markers
(2000) [Artigo de periódico]Random amplified polymorphic DNA markers (RAPD) were used to estimate the variability of 14 genotypes of Brazilian wheat (Triticum aestivum L.), using a set of 50 random 10-mer primers. A total of 256 reproducibly scorable ... -
Extremely large magnetic-field-effects on the impedance response of TiO2 quantum dots
(2019) [Artigo de periódico]Here, we report large magnetoresistance and magnetocapacitance response of undoped TiO 2 quantum dots weighting the contribution of both grain and grain boundaries by means of impedance spectroscopy. We also performed a ... -
Extremely low nucleotide diversity among thirty-six new chloroplast genome sequences from Aldama (Heliantheae, Asteraceae) and comparative chloroplast genomics analyses with closely related genera
(2021) [Artigo de periódico]Aldama (Heliantheae, Asteraceae) is a diverse genus in the sunflower family. To date, nearly 200 Asteraceae chloroplast genomes have been sequenced, but the plastomes of Aldama remain undescribed. Plastomes in Asteraceae ... -
Extreme pressure forecasting methodology for the hydraulic jump downstream of a low head spillway
