Influence of Th1/Th2 cytokines and nitric oxide in murine systemic infection induced by Sporothrix schenckii
(Mycopathologia, 2006-01-01) [Artigo]
In an attempt to elucidate the effects of Sporothrix schenckii infection on the immune response, our laboratory has developed a murine model of disseminated sporotrichosis. Helper T cells can be further subdivided into Th1 ...
A 12-month follow-up of hypopigmentation after laser hair removal
(Journal of Cosmetic and Laser Therapy, 2013-04-01) [Artigo]
Introduction: Laser hair removal is becoming an increasingly popular alternative to traditional methods such as shaving, waxing, among other methods. Semiconductor diode lasers are considered the most efficient light sources ...
Differential gene expression by Paracoccidioides brasiliensis in host interaction conditions: Representational difference analysis identifies candidate genes associated with fungal pathogenesis
(Microbes and Infection, 2006-10-01) [Artigo]
Paracoccidioides brasiliensis causes infection by the host inhalation of airborne propagules of the mycelia phase of the fungus. These particles reach the lungs, and disseminate to virtually all organs. Here we describe ...
Glycolipid Sensing and Innate Immunity in Paracoccidioidomycosis
(Mycopathologia, 2014-10-01) [Artigo]
Distinct glycolipid profiles are described in microorganisms, which have been shown to modulate the innate immune system. We tested the hypothesis that glycosphingolipids from Paracoccidioides brasiliensis have immunomodulatory ...
Effects of liver S9 enzymes on somalargine and solasodine cytotoxicity and mass spectrometric fragmentation
(European Food Research and Technology, 2013-04-16) [Artigo]
The steroidal glycoalkaloid solamargine and its parent aglycone solasodine, isolated from Solanum palinacanthum, were studied in vitro for cytotoxicity and biotransformation by the hepatic S9 fraction as the metabolic ...
ABO, Lewis, secretor and non-secretor phenotypes in patients infected or uninfected by the Helicobacter pylori bacillus
(São Paulo Medical Journal, 2002-03-01) [Artigo]
CONTEXT: Epidemiological studies have demonstrated higher frequencies of the O blood group and the non-secretor phenotype of ABH antigens among patients suffering from peptic ulcers. Since Helicobacter pylori has been ...
Anti-Helicobacter pylori activity and oxidative burst inhibition by the naphthoquinone 5-methoxy-3,4-dehydroxanthomegnin from Paepalanthus latipes
(Revista Brasileira de Farmacognosia, 2012-02-01) [Artigo]
Helicobacter pylori is a bacterium recognized as the major cause of chronic gastritis and peptic ulcers. Infection by H. pylori induces inflammatory responses and pathological changes in the gastric microenvironment. The ...
Curcumin-mediated photodynamic inactivation of Candida albicans in a murine model of oral candidiasis
(Medical Mycology, 2013-04-01) [Artigo]
In vitro investigations of curcumin-mediated photodynamic therapy (PDT) are encouraging, but there is a lack of reliable in vivo evidence of its efficacy. This study describes the photoinactivation of Candida albicans in ...
It only takes one to do many jobs: Amphotericin B as antifungal and immunomodulatory drug
(Frontiers in Microbiology, 2012-12-01) [Artigo]
Amphotericin B acts through pore formation at the cell membrane after binding to ergosterol is an accepted dogma about the action mechanism of this antifungal, and this sentence is widely found in the literature. But after ...
