In vitro effects of photobiomodulation applied to gingival fibroblasts cultured on titanium and zirconia surfaces and exposed to LPS from Escherichia coli
(2020-01-01)
Photobiomodulation (PBM) therapy is used to stimulate cell proliferation and metabolism, as well as reduce inflammatory cytokine synthesis, which plays a main role in the long-term stability of implants. This study assessed ...
Comparison of GentleWave system and passive ultrasonic irrigation with minimally invasive and conventional instrumentation against LPS in infected root canals
(2022-12-01)
This study compared the effectiveness of GentleWave system (GWS) and passive ultrasonic irrigation (PUI) in removing lipopolysaccharides (LPS) from infected root canals after minimally invasive (MIT) and conventional ...
Contribution of Vasoactive Intestinal Peptide to Immune Homeostasis in Trophoblast-Maternal Leukocyte Interaction under LPS Stimulation
(Karger, 2013-12)
Background/Aims: The maternal-fetal interface is a unique immunological site that generates an adequate microenvironment during pregnancy, recognizing and eliminating infections and tolerating the trophoblast/placenta unit. ...
Progesterone is essential for protecting against LPS-induced pregnancy loss. LIF as a potential mediator of the anti-inflammatory effect of progesterone
(Public Library Science, 2013-02-07)
Abstract Lipopolysaccharide (LPS) administration to mice on day 7 of gestation led to 100% embryonic resorption after 24 h. In this model, nitric oxide is fundamental for the resorption process. Progesterone may be ...
Lipopolysaccharides and trophic factors regulate the LPS receptor complex in nodose and trigeminal neurons
(Elsevier, 2014-09)
Binding of bacterial lipopolysaccharides (LPS) to toll-like receptor 4 (TLR4) triggers an innate immunoresponse associated with pain and inflammation. The expression, and to a greater extent the regulation of TLR4 and its ...
Actinobacillus actinomycetemcomitans lipopolysaccharide induces interleukin-6 expression through multiple mitogen-activated protein kinase pathways in periodontal ligament fibroblasts
(Blackwell Publishing, 2006-12-01)
Actinobacillus actinomycetemcomitans plays a major role in the pathogenesis of aggressive periodontitis. Lipopolysaccharide (LPS) derived from A. actinomycetemcomitans is a key factor in inflammatory cytokine generation ...
Clinical and laboratory evaluation of horses after intraperitoneal injection of lipopolysaccharide (LPS)
(William E Jones Dvm, 1999-03-01)
Horses are very sensitive to Gram-negative bacterial lipopolysaccharides (LPS) which, when introduced into the blood stream, induce several responses mediated by endogenous pro-inflammatory mediators originating from ...
