Eugenol is widely used in dentistry to relieve pain. We have recently demonstrated voltage-gated Na(+) and Ca(2+) channels as molecular targets for its analgesic effects, and hypothesized that eugenol acts on P2X(3), another pain receptor expressed in trigeminal ganglion (TG), and tested the effects of eugenol by whole-cell patch clamp and Ca(2+) imaging techniques. In the present study, we inv...

AIMS AND OBJECTIVES The aim of this study was to assess the outcome of eugenol-free and eugenol-containing cements on the bond strength of resin cement. MATERIALS AND METHODS Dentin was exposed in five groups of extracted teeth (20 specimens each). In Group 1, specimens were not given temporary cementation. In Groups 2 and 3, specimens were given temporary restoration fixed with eugenol-free ...

Enterohemorrhagic Escherichia coli O157:H7 (EHEC) has caused foodborne outbreaks worldwide and the bacterium forms antimicrobial-tolerant biofilms. We investigated the abilities of various plant essential oils and their components to inhibit biofilm formation by EHEC. Bay, clove, pimento berry oils and their major common constituent eugenol at 0.005% (v/v) were found to markedly inhibit EHEC bi...

Eugenol, a methoxyphenol component of clove oil, suppresses cyclooxygenase-2 expression, while eugenol dimers prevent nuclear factor-kappaB (NF-kappaB) activation and inflammatory cytokine expression in lipopolysaccharide-stimulated macrophages. Our aim was to examine the in vivo anti-inflammatory effects of eugenol. BALB/c mice were divided into four groups. Mice received saline [0.05 ml intra...

Water solution of volatile organic compounds (VOCs) in air, especially explosive materials, is required to detect VOCs by biosensors efficiently. We developed a collecting device like olfactory mechanism of animals: thin film of water including odorant binding proteins (OBPs), which play a major role in transport of hydrophobic odor molecules to olfactory receptors. Thin liquid film was generat...

In aquaculture, activities with anesthetic compounds are usually used in order to ensure the welfare of farmed fish, allowing handling out of water with decreased trauma by stress. Presently, there is no information about anesthetic action of eugenol in early life stages of Nile tilapia (Oreochromis niloticus). The objective of this study was to evaluate different concentrations of eugenol for ...

BACKGROUND A multicenter observational study was conducted in Italy to assess the safety of micafungin in the daily clinical practice for the treatment of proven and suspected invasive candidiasis (IC), as well as to describe rates of clinical response to micafungin treatment. METHODS From October 2010 to March 2012, data from consecutive eligible neonate, pediatric, and adult patients treate...

The essential oil (EO) of clove bud dried fruits from Eugenia caryophyllus was obtained by a conventional hydrodistillation process in an excellent yield (11.7 %). Its chemical composition was analyzed by GC-MS, identifying eugenol as a main constituent (60.5%). Four eugenol-like molecules, γ-diisoeugenol, hydroxymethyleugenol, dihydroeugenol and 1,3-dioxanylphenol, were synthesized using eugen...

4-Allyl-4-hydroperoxy-2-methoxycyclohexa-2,5-dienone (5) was synthesized by photooxygenation of commercially available Eugenol in the presence of tetraphenylporphyrin (TPP) as a singlet oxygen sensitizer. The brief and one-pot syntheses of some natural product skeletons were conducted using the corresponding allylic hydroperoxide at different temperatures (0 o C and room temperature) with potas...

Aim. Acute pancreatitis is an inflammatory intra-abdominal disease, which takes a severe form in 15-20% of patients and can result in high mortality especially when complicated by acute renal failure. The aim of this study is to assess the possible reduction in the extent of acute kidney injury after administration of eugenol in an experimental model of acute pancreatitis. Materials and Methods...
