[6]-Gingerol, a naturally occurring plant phenol, is one of the major components of fresh ginger (Zingiber officinale Roscoe, Zingiberaceae) and has diverse pharmacologic effects. Here, we describe its novel anti-oxidant, anti-apoptotic, and anti-inflammatory activities in vitro and in vivo. In vitro, pre-treatment with [6]-gingerol reduced UVB-induced intracellular reactive oxygen species levels, activation of caspase-3, -8, -9, and Fas expression. It also reduced UVB-induced expression and tra

The objective of this study is to investigate the contributing effect of the nuclear transcription factor-erythroid 2-related factor 2 (Nrf2)-mediated signaling pathway on the indirect antioxidant capacity of caffeic acid phenethyl ester (CAPE) against oxidative stress in HepG2 cells. The result of an antioxidant response element (ARE)-luciferase assay showed that CAPE stimulated ARE promoter activity resulting in increased transcriptional and translational activities of heme oxygenase-1 (HO-1).

Papiliocin is a novel 37-residue cecropin-like peptide isolated recently from the swallowtail butterfly, Papilio xuthus. With the aim of identifying a potent antimicrobial peptide, we tested papiliocin in a variety of biological and biophysical assays, demonstrating that the peptide possesses very low cytotoxicity against mammalian cells and high bacterial cell selectivity, particularly against Gram-negative bacteria as well as high anti-inflammatory activity. Using LPS-stimulated macrophage RAW

Lung cancer tissues and cell lines express OGFR. Morphine interacts with OGFR and may suppress lung cancer progression.

OBJECTIVE: To determine bispectral index (BIS) values produced by equipotent concentrations of commonly used volatile anaesthetics. METHODS: Female patients undergoing thyroidectomy were randomly assigned to receive isoflurane, sevoflurane or desflurane anaesthesia. After induction, anaesthesia was maintained by the volatile agent at 1 minimum alveolar concentration and supplemented with remifentanil infusion. BIS values were recorded during 1 h surgical anaesthesia after a 15 min equilibrium ph

Salivary excretion under propofol/remifentanil anesthesia is greater than under sevoflurane anesthesia during laryngeal surgery.

Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is closely related to West Nile (WN), yellow fever (YF), and dengue (DEN) viruses. Its plus-strand genomic RNA carries a single open reading frame encoding a polyprotein that is cleaved into three structural (C, prM/M, and E) and at least seven nonstructural (NS1/NS1', NS2A, NS2B, NS3, NS4A, NS4B, and NS5) proteins, based on previous work with WNV, YFV, and DENV. Here, we aimed to profile experimentally all the viral proteins found

If coagulopathy is a concern during PLIF, then, a HES with low MW/DS in a saline-based medium (Voluven) may be a better alternative than a HES with high MW/DS in a balanced salt medium (Hextend).

There are some controversies over the contribution of Na+/Ca2+ exchanger (NCX) to the regulation of cytosolic Ca2+ concentration ([Ca2+]c) in smooth muscle. To prove the functional role of Na+/Ca2+ exchanger, we examined whether the removal of extracelluar Na+ could affect [Ca2+]c of rabbit cerebral arterial smooth muscle. The fluorescence ratio of fura-2 (R(340/380)) was measured in the single myocyte of rabbit middle cerebral artery and Na+ was substituted with the same concentration of NMDG+

Abstract The working electrode of a Dye–sensitized Solar Cell (DSC) is a fluorine‐doped tin oxide (FTO) glass substrate pasted with nano‐porous TiO 2 . Under the illumination, dye molecules are excited and electrons are emitted. The electrons pass through two interfaces of dye/TiO 2 and TiO 2 /FTO. Therefore, electron of the TiO 2 conduction band combines with I 3 ‐ ion of the electrolyte. A compact layer between the FTO and nano‐porous TiO 2 layer makes adherence of TiO 2 to FTO surface improve

Fentanyl (1.5 µg/kg) administered intravenously during anesthetic induction is unlikely to increase the incidence and severity of significant reflex bradycardia in patients undergoing major abdominal surgery.
