The predictive power of implied volatility: Evidence from 35 futures markets
Abstract Using data from 35 futures options markets from eight separate exchanges, we test how well the implied volatilities (IVs) embedded in option prices predict subsequently realized volatility… Expand
Fundamental role of ClC-3 in volume-sensitive Cl- channel function and cell volume regulation in AGS cells.

Volume regulation is essential for cell function, but it is unknown which channels are involved in a regulatory volume decrease (RVD) in human gastric epithelial cells. Exposure to a hypotonic… Expand
Low-dose radiation stimulates the proliferation of normal human lung fibroblasts via a transient activation of Raf and Akt.
The biological effects of low-dose radiation have been investigated and debated for more than a century, but its cellular effects and regulatory mechanisms remain poorly understood. This study shows… Expand

MicroRNAs have crucial roles in lung cancer cell development. They regulate cell growth, proliferation and migration by mediating the expression of tumor suppressor genes and oncogenes. We identified… Expand
Change of obstruction level during drug‐induced sleep endoscopy according to sedation depth in obstructive sleep apnea
We evaluated the change in upper airway collapse according to the depth of sedation during drug‐induced sleep endoscopy (DISE), as well as characteristics possibly associated with that change.
A Prospective, Randomized Comparison of the Effects of Inhaled Sevoflurane Anesthesia and Propofol/Remifentanil Intravenous Anesthesia on Salivary Excretion During Laryngeal Microsurgery
BACKGROUND:One of the goals of anesthesia for laryngeal microsurgery is to provide a clear surgical view, and therefore anesthetics that produce less saliva are desirable. Sevoflurane inhalation… Expand
Hypoxia-augmented constriction of deep femoral artery mediated by inhibition of eNOS in smooth muscle.

In contrast to the conventional belief that systemic arteries dilate under hypoxia, we found that α-adrenergic contraction of rat deep femoral artery (DFA) is largely augmented by hypoxia (HVC(DFA))… Expand
Analysis of TiO2 thickness effect on characteristic of a dye-sensitized solar cell by using electrochemical impedance spectroscopy
Abstract Dye-sensitized solar cell (DSC) consists of a TiO 2 nano film of the photo electrode, dye molecules on the surface of the TiO 2 film, an electrolyte layer and a counter electrode. Among… Expand
Chemical Constituents of the Ficus elastica Leaves and Their Antioxidant Activities
Ficus elastica Roxb. Ex Hornem also known as rubber tree, is a tree species belonging to the Moraceae family. This plant grows profusely without any agronomic management and survives well under… Expand
Residual Status and Dissipation Pattern of Metalaxyl in Chinese Cabbages (Brassica campestris) Grown under Greenhouse Conditions
The present investigation was undertaken to generate information about the residue levels and degradation rate of metalaxyl from Chinese cabbages (Brassica campestris) grown under greenhouse… Expand
