In vitro effect of caffeic acid phenethyl ester on matrix metalloproteinases (MMP-1 and MMP-9) and their inhibitor (TIMP-1) in lipopolysaccharide-activated human monocytes
(Archives Of Oral Biology, 2015) [Artigo]
The role of matrix metalloproteinases (MMPs) in tissue degradation has become evident in many diseases and great interest therefore exists in the pharmacological control of the activity of these enzymes. This study evaluated ...
Invasion of differentiated intestinal caco-2 cells is a sporadic property among atypical enteropathogenic escherichia coli strains carrying common intimin subtypes
(Pathogens And Disease, 2014-03-01) [Artigo]
The Effect of Propolis on Th1/Th2 Cytokine Expression and Production by Melanoma-bearing Mice Submitted to Stress
(Phytotherapy Research, 2010-10-01) [Artigo]
Since propolis possesses immunomodulatory and antitumoral activities, this work aimed to evaluate its effect on Th1 (IL-2 and IFN-gamma) and Th2 (IL-4 and IL-10) cytokines mRNA expression and production by melanoma-bearing ...
Caracterização filogenética de amostras do vírus da imunodeficiência felina (FIV) do Estado de São Paulo
(Pesquisa Veterinária Brasileira, 2007-11-01) [Artigo]
O vírus da imunodeficiência felina (FIV) é um lentivírus que causa distúrbios imunológicos em gatos domésticos. Devido à alta variabilidade genética do FIV, já foram identificados cinco subtipos (A a E) e a diversidade ...

(Archives Of Virology, 2015-05-01) [Artigo]
St. Louis encephalitis virus (SLEV), a member of the family Flaviviridae, genus Flavivirus, is a causative agent of encephalitis in the Americas. In Brazil, sporadic cases of SLEV infection have been reported since 1953, ...
PRP8 intein in Ajellomycetaceae family pathogens: Sequence analysis, splicing evaluation and homing endonuclease activity
(Fungal Genetics and Biology, 2011-02-01) [Artigo]
Inteins are intervening sequences that are transcribed and translated with flanking host protein sequences and then self-excised by protein splicing. Bi-functional inteins also contain a homing endonuclease responsible for ...
Chemomodulation of human dendritic cell function by antineoplastic agents in low noncytotoxic concentrations
(Journal of Translational Medicine, 2009-07-10) [Artigo]
The dose-delivery schedule of conventional chemotherapy, which determines its efficacy and toxicity, is based on the maximum tolerated dose. This strategy has lead to cure and disease control in a significant number of ...
Chemotherapeutic agents in low noncytotoxic concentrations increase immunogenicity of human colon cancer cells
(Cellular Oncology, 2011-04-01) [Artigo]
Background We have recently reported that chemotherapeutic agents in ultra low noncytotoxic concentrations may block the ability of tumor cells to suppress functional activation of dendritic cells (DCs).Methods HCT-116 ...
