Epoxyeicosatrienoic acids (EETs) are derived from arachidonic acid and metabolized by soluble epoxide hydrolase (sEH). The role of EETs in synaptic function in the central nervous system is still largely unknown. We found that pharmacological inhibition of sEH to stabilize endogenous EETs and exogenous 14,15-EET significantly increased the field excitatory postsynaptic potential (fEPSP) response in the CA1 area of the hippocampus, while additionally enhancing high-frequency stimulation- (HFS-) induced long-term potentiation (LTP) and forskolin- (FSK-) induced LTP...

Activation of soluble epoxide hydrolase (sEH) is associated with endothelial dysfunction in hypertension, though the underlying mechanisms are inadequately understood and the role of endoplasmic reticulum (ER) stress is yet to be studied in detail. Tetramethylpyrazine (TMP), a major bioactive ingredient of Chinese herb Chuanxiong, is well-known for its cardiovascular benefits. Nevertheless, whether TMP may protect vascular endothelium from ER stress and whether regulation of sEH is involved remain unknown. This study aimed at investigating the role of ER stress in angiotensin-II (Ang-II)-induced sEH dysregulation and elucidating the significance of ER stress regulation in the vasoprotective effect of TMP...

Preeclampsia is a serious complication of pregnancy characterized by the development of vasospasm, hypertension and often associated with proteinuria after the 20th week of gestation. Because termination of pregnancy results in the most efficacious resolution of preeclampsia, it is a leading cause of premature delivery worldwide. In pregnancy, 14,15-epoxyeicosatrienoic acids (EETs) have been shown to facilitate uterine blood flow during preeclampsia, in which the classic vasodilator agents such as nitric oxide and prostacyclin are reduced...

The reaction of Na[H2B(mt)2] (mt = 2-mercapto, 3-methylimidazol-1-yl, methimazolyl) with [Ru(X)Cl(CO)(PPh3)n] (n = 3 X = H; n = 2 BO2C6H4, SiCl3, SiMe3) affords the complexes [Ru(X)(CO)(PPh3){κ(2)-H,S,S'-H2B(mt)2}]. Evidence is presented to also support the transient formation of [Ru(X)(CO)(PPh3){κ(2)-H,S,S'-H2B(mt)2}] (X = CH[double bond, length as m-dash]CHPh, Ph) via a similar strategy, although these are unstable. The osmium complex [OsH(CO)(PPh3){κ(2)-H,S,S'-H2B(mt)2}] is similarly obtained from [OsHCl(CO)(PPh3)3] or [OsH(NCMe)2(CO)(PPh3)2]BF4...

OBJECTIVE Spinal cord injury (SCI) is a major complication of spinal fractures in patients with ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH). Due to the uncommon nature of these conditions, existing literature consists of relatively small case series without detailed neurological data. This study aims to investigate the incidence, predictors, and sequelae of SCI in patients with a traumatic fracture of the ankylosed spine. METHODS The study included all patients older than 18 years of age with AS or DISH who presented to two affiliated tertiary care centers between January 1, 1990, and January 1, 2016, and had a traumatic fracture of the spine...

Microsomal and soluble epoxide hydrolase (mEH and sEH) fulfill apparently distinct roles: Whereas mEH detoxifies xenobiotics, sEH hydrolyzes fatty acid (FA) signaling molecules and is thus implicated in a variety of physiological functions. These epoxy FAs comprise epoxyeicosatrienoic acids (EETs) and epoxy-octadecenoic acids (EpOMEs), which are formed by CYP epoxygenases from arachidonic acid (AA) and linoleic acid, respectively, and then are hydrolyzed to their respective diols, the so-called DHETs and DiHOMEs...

Cardiac enzymes such as cytochrome P450 2J2 (CYP2J2) metabolize arachidonic acid (AA) to cardioprotective epoxyeicosatrienoic acids (EETs), which in turn are metabolized by soluble epoxide hydrolase (sEH) to dihydroxyeicosatrienoic acids (DHETs). As EETs and less potent DHETs exhibit cardioprotective and vasoprotective functions, optimum levels of cardiac EETs are paramount in cardiac homeostasis. Previously, we demonstrated that dronedarone, amiodarone and their main metabolites, namely N-desbutyldronedarone (NDBD) and N-desethylamiodarone (NDEA), potently inhibit human cardiac CYP2J2-mediated astemizole metabolism in vitro...

Tumor necrosis factor-inducible gene 6 protein (TSG-6) has recently been shown to protect the liver from acute damage. However, the mechanism underlying the effect of TSG-6 on the liver remains unclear. Autophagy is a catabolic process that targets cell components to lysosomes for degradation, and its functions are reported to be dysregulated in liver diseases. Here we investigate whether TSG-6 promotes liver regeneration by inducing autophagic clearance in damaged livers. Mice fed a methionine choline-deficient diet supplemented with 0...

This article describes the mechanisms underlying electronic interactions between surface passivating ligands and (CdSe)34 semiconductor cluster molecules (SCMs) that facilitate band-gap engineering through the delocalization of hole wave functions without altering their inorganic core. We show here both experimentally and through density functional theory calculations that the expansion of the hole wave function beyond the SCM boundary into the ligand monolayer depends not only on the pre-binding energetic alignment of interfacial orbitals between the SCM and surface passivating ligands but is also strongly influenced by definable ligand structural parameters such as the extent of their π-conjugation [π-delocalization energy; pyrene (Py), anthracene (Anth), naphthalene (Naph), and phenyl (Ph)], binding mode [dithiocarbamate (DTC, -NH-CS2(-)), carboxylate (-COO(-)), and amine (-NH2)], and binding head group [-SH, -SeH, and -TeH]...

Coronary reactive hyperemia (CRH) protects the heart against ischemia. Adenosine A2AAR-deficient (A2AAR(-/-)) mice have increased expression of soluble epoxide hydrolase (sEH); the enzyme responsible for breaking down the cardioprotective epoxyeicosatrienoic acids (EETs) to dihydroxyeicosatrienoic acids (DHETs). sEH-inhibition enhances CRH, increases EETs, and modulates oxylipin profiles. We investigated the changes of oxylipins and their impact on CRH in A2AAR(-/-) and wild type (WT) mice. We hypothesized that the attenuated CRH in A2AAR(-/-) mice is mediated by changes in oxylipin profiles, and that it can be reversed by either sEH- or ω-hydroxylases-inhibition...
