BACKGROUND The use of electronic cigarettes (e-cigs) is increasing and there is widespread perception that e-cigs are safe. E-cigs contain harmful chemicals; more research is needed to evaluate the safety of e-cig use. Our aim was to investigate the effects of e-cigs on the inflammatory response of human neutrophils. METHODS Neutrophils were exposed to e-cig vapour extract (ECVE) and the expr...

Childhood obesity is related to a cascade of neuroendocrine inflammatory changes. However, there remains a gap in the current literature regarding the possible occurrence of these changes in overweight/obese infants. The objective of this study was to evaluate adipokines, cortisol, brain-derived neurotrophic factor (BDNF) and redox status in overweight/obese infants versus normal-weight peers. ...

Spinal cord injury (SCI) actuate to complex cellular and molecular interactions within the central nervous system in a heave to repair the initial tissue damage. The pathophysiology of acute spinal cord injury (SCI) involves primary and secondary mechanisms. Neuroinflammation is an important secondary injury process in SCI. The local inflammatory microenvironment within the injured spinal cord ...

Oncostatin M (OM) is a pleiotropic cytokine produced late in the activation cycle of T cells and macrophages. In vitro it shares properties with related proteins of the IL-6 family of cytokines; however, its in vivo properties and physiological function are as yet ill defined. We show that administration of OM inhibited bacterial LPS-induced production of TNF-alpha and lethality in a dose-depen...

BACKGROUND We aim to evaluate the metabolic and inflammatory responses after ERCP procedure in patients who have common bile duct stones. METHODS Between September 2009 and October 2010, we studied prospectively 50 patients who diagnosed with common bile duct stones. Our study was included patients who had previously been suspected with common biliary duct stone via radiological and biochemic...

Th2-eosinophil immune responses are well known for mediating host defence against helminths. Herein we describe a function of Th2-eosinophil responses in counteracting the development of arthritis. In two independent models of arthritis, Nippostrongylus brasiliensis infection leads to Th2 and eosinophil accumulation in the joints associated with robust inhibition of arthritis and protection fro...

BACKGROUND The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE). METHODS The anti-inflammatory effects of IFE against nitric oxide (NO), PGE(2), TNF-α, and IL-6 release, as well as NF-κB and MAP kinase activation wer...

Alarm signals generated at inflammatory foci reach the vascular lumen to attract immune cells towards the affected tissue. Different leucocyte subsets decipher and integrate these complex signals in order to make adequate decisions for their migration towards the inflamed tissue. Soluble cues (cytokines and chemokines) and membrane receptors in both endothelium and leucocytes orchestrate the co...

Periapical inflammatory responses occur as a consequence of bacterial infection of the dental pulp, as a result of caries, trauma, or iatrogenic insult. Periapical inflammation stimulates the formation of granulomas and cysts, with the destruction of bone. These inflammatory responses are complex and consist of diverse elements. Immediate-type responses--including vasodilatation, increased vasc...
