Three types of compensation electrode are analyzed, which give a more linear phase shift to the propagating optical beam for the planar electrooptic prism deflector. For Types I and III, the more linear phase shift is achieved by varying the slope of the central tilt electrode at the edge regions. For Type II, the more linear phase shift is achieved by cascading an electrode, giving an opposite...

The Valsalva maneuver (VM) produces large and abrupt changes in mean arterial pressure (MAP) that challenge cerebral blood flow and oxygenation. We examined the effect of VM intensity on middle cerebral artery blood velocity (MCAv) and cortical oxygenation responses during (phases I-III) and following (phase IV) a VM. Healthy participants (n = 20 mean ± SD: 27 ± 7 years) completed 30 and 90% of...

OBJECTIVES Respiratory symptoms are associated with spirometry results but more strongly with smoking history, suggesting that alterations in the lung other than those revealed by spirometry contribute to cause symptoms. Smoking may cause obstruction of peripheral airways that is poorly detected by spirometry. The slope of phase III of the single-breath nitrogen (N(2)) test detects smoking-indu...

Perampanel (PER) is a novel noncompetitive AMPA-receptor antagonist approved in over 40 countries for treatment of partial seizures. The safety and tolerability of PER have been well-documented in three double-blind, randomized, placebo (PBO)-controlled Phase III studies and an open-label extension (OLE). This post hoc analysis evaluated the occurrence and characteristics of the most common tre...

Endogenous ghrelin causes interdigestive contractions of the stomach in rats. In contrast, previous studies showed that 5-HT(3) and 5-HT(4) receptors were involved in regulating intestinal interdigestive contractions. We studied the possible role of endogenous ghrelin and 5-HT regulating interdigestive gastrointestinal (GI) contractions in rats. Four strain gauge transducers were implanted on t...

The effects of time, composition and history of preparation of the aqueous phase on the liquidliquid extraction of chromium(III) with Aliquat 336 from the aqueous alkaline solutions containing chlorides were studied. At time far from the equilibrium the yield and initial rate of the chromium(III) extraction depend on NaOH concentration, ionic strength of the aqueous phase and the way of its pre...

INTRODUCTION Our aim was to assess the visibility and efficiency of graphic health warnings (GHWs) on waterpipe tobacco packs (WTPs) and to explore other more effective places to display them for better impact. We also evaluated the visibility of GHWs when placed on the waterpipe device. METHODS We conducted 3 cross-sectional study phases using face-to-face survey questionnaires in 2014-2015. P...
