The Endoscopic Management of Sinus Mucoceles following Orbital Decompression (1994)

Sinusitis is a reported complication after orbital decompression for endocrine ophthalmopathy. Herniation of orbital fat may lead to ostiomeatal obstruction and secondary involvement of the dependent maxillary, frontal, and ethmoid sinuses. However, the occurrence of mucoceles appears to be rare, and we were unable to identify a prior report of this condition. We present three cases of maxillary and ethmoid sinus mucoceles after transantral decompressions for orbital proptosis. All three cases subsequently underwent endoscopic sinus surgery for marsupialization of the mucoceles. The diagnosis and management of these lesions is a challenging problem. The coexistence of exophthalmos and the fact that sinus disease may present many years after orbital decompression increases the difficulty of making an appropriate diagnosis. In addition, the surgical approach to this problem is difficult because the surgeon must avoid damage to the low-lying orbit and simultaneously decompress the infection and reestablish adequate sinus drainage. Physician awareness of this problem is important for timely diagnosis. We review the anatomy of this condition and describe a practical approach to diagnosis and management of this problem.

NOVEL TOUCH-FREE DRIVE, SENSE, AND TUNING MECHANISM FOR ALL-DIELECTRIC MICRO-SHELL GYROSCOPE (2014)

This paper demonstrates, for the first time, touch-free electrical sensing and frequency tuning of an all-dielectric microshell gyroscope without electrically-conductive coatings. Current vibratory gyroscope technologies rely on an electrically-conductive structure or conductive coatings These conductive materials and coatings often compromise the quality factor (Q), thermal stability, and symmetry necessary to achieve navigation grade performance. The novel mechanism presented herein is based on the manipulation of electric fringe fields and their gradients. Several highly-doped Si electrode structures placed adjacent to the micro-shell can drive, sense, and frequency-tune the micro-shell as experimentally demonstrated in this paper. Micro-shell n = 2 wineglass vibration modes with Q > 10 4 and frequency splits f < 50Hz are experimentally demonstrated using the touch-free gradient field transduction mechanism. Tuning of up to 4 Hz is demonstrated for a modest bias of 20V.
Mechanisms of electroluminescence during aging of polyethylene (1985)

The study of electrical aging of polyethylene subjected to a 50 Hz ac voltage has shown that electroluminescence occured in the bulk of the polymer. These light emissions (detected in the visible range of wavelength) were due to the buildup of space charge around the electrodes. In a previous paper [J. Appl. Phys. 54, 1532 (1983)] results concerning the role of dissolved gases in polyethylene were presented, where particular attention was paid to electroluminescence effects. The present work aims to answer the two following questions: (1) what are the mechanisms causing the electroluminescence? (2) what is the nature of the luminescent centers? Study of the light emission with respect to the applied voltage form, the frequency, (when ac voltage is applied) and the voltage amplitude, shows that the light emission is due to radiative recombinations of carriers injected through the metal-dielectric interface following the Fowler–Nordheim effect. This process requires a double injection of carriers. The influence of electrode material on the light emission intensity is then shown, which is in good agreement with the injection mechanism proposed. The luminescent centers are carriers stabilized by deep traps in the polyethylene.
Full 3D translational and rotational optical control of multiple rod‐shaped bacteria (2010)

The class of rod-shaped bacteria is an important example of non-spherical objects where defined alignment is desired for the observation of intracellular processes or studies of the flagella. However, all available methods for orientational control of rod-shaped bacteria are either limited with respect to the accessible rotational axes or feasible angles or restricted to one single bacterium. In this paper we demonstrate a scheme to orientate rod-shaped bacteria with holographic optical tweezers (HOT) in any direction. While these bacteria have a strong preference to align along the direction of the incident laser beam, our scheme provides for the first time full rotational control of multiple bacteria with respect to any arbitrary axis. In combination with the translational control HOT inherently provide, this enables full control of all three translational and the two important rotational degrees of freedom of multiple rod-shaped bacteria and allows one to arrange them in any desired configuration.

per well) were added to a serial dilution of compounds in 96-well plates. After incubation for 44 h, 50 µL of the MTT solution (1.1 mg/mL) was added to each well and incubated for an additional 4 h. The colored formazan crystal produced from the MTT was dissolv-ed in 150 µL of dimethyl sulfoxide (DMSO). The optical density (OD) values of the solutions were measured at 540 nm using a plate reader.

Hypercube Algorithm for Radiosity in a Ray Tracing Environment (2005)

Two different approaches to realistic image synthesis are Ray tracing and radiosity. Each method falls short in their attempts to model global illumination present in most environments. A more general model includes the specular and diffuse reflection of both these methods but the combination requires prohibitive computation. The algorithm presented here extends the standard ray tracing algorithm by adding diffuse rays, while eliminating unnecessary radiosity calculations. The data separation used here is based on the heuristic that light rays, as well as shadow rays intersect objects which are nearby more often those that are more distant. Although that heuristic seems sound, its accuracy is being tested by monitoring the results of prccessing a large number of different scenes of various complexity.

ELECTROKINETIC PROPERTIES, IN VITRO DISSOLUTION, AND PROSPECTIVE HEMOAND BIOCOMPATIBILITY OF TITANIUM OXIDE AND OXYNITRIDE FILMS FOR CARDIOVASCULAR STENTS (2015)

A state of titanium oxide and oxynitride coatings on L316 steel has been studied before and after their contact with model biological fluids. Electrokinetic investigation in 1 mmol potassium chloride showed significant (more than 10 times) fall of magnitude of electrostatic potential of thin (200–300 nm) titanium films at pH changing in the range of 5–9 units during 2 h. Nevertheless, zeta-potential of all samples had negative charge under pH > 6.5. Long-term (5 weeks) contact of samples with simulated body fluid (SBF) promoted steel corrosion and titanium oxide and oxynitride films dissolution. On the other hand, sodium and chloride ions precipitation and sodium chloride crystals formation occurred on the samples. Of positive fact is an absence of calcification of tested artificial surfaces in conditions of long-term being in SBF solution. It is supposed decreasing hazard of fast thrombosis and loss of materials functional properties. According to in vitro experiment conducted, prospective biocompatibility of materials tested before and after their contact with SBF lines up following manner: Ti–O–N (1/3) > Ti–O–N (1/1), TiO2 > Steel. It may be explained by: 1) the corrosion-preventive properties of thin titanium oxide and oxynitride films;2) a store of surface negative charge for Ti–O–N (1/3) film; 3) minor augmentation of mass and thickness of titanium films connected with speed of mineralization processes on the interface of solution/solid body. At the same time, initial (before SBF contact) differences of samples wettability became equal. Modifying effect of model biological fluids on physicochemical characteristics of materials tested (roughness enhancement, a reduction or reversion of surface negative potential, sharp augmentation of surface hydrofilicity) should took into account under titanium oxide and oxynitride films formation and a forecast of their optimal biological properties as the materials for cardiovascular stents.
Low‐frequency symmetric waves in fluid‐filled boreholes and pipes with radial layering (2008)

ABSTRACT Many tasks in geophysics and acoustics require estimation of mode velocities in cylindrically layered media. For example, acoustic logging or monitoring in open and cased boreholes need to account for radial inhomogeneity caused by layers inside the borehole (sand screen, gravel pack, casing) as well as layers outside (cement, altered and unaltered formation layers). For these purposes it is convenient to study a general model of cylindrically layered media with inner fluid layer and free surface on the outside. Unbounded surrounding media can be described as a limiting case of this general model when thickness of the outer layer is infinite. At low frequencies such composite media support two symmetric modes called Stoneley (tube) and plate (extensional) wave. Simple expressions are obtained for these two mode velocities valid at zero frequency. They are written in a general form using elements of a propagator matrix describing axisymmetric waves in the entire layered composite. This allows one to apply the same formalism and compute velocities for n ‐layered composites as well as anisotropic pipes. It is demonstrated that the model of periodical cylindrical layers is equivalent to a homogeneous radially transversely isotropic media when the number of periods increases to infinity, whereas their thickness goes to zero. Numerical examples confirm good validity of obtained expressions and suggest that even small number of periods may already be well described by equivalent homogeneous anisotropic media.
Structurally delineating stromal interaction molecules as the endoplasmic reticulum calcium sensors and regulators of calcium release‐activated calcium entry (2009)

The endoplasmic reticulum (ER) lumen stores a crucial source of calcium (Ca2+) maintained orders of magnitude higher than the cytosol for the activation of a plethora of cellular responses transmitted in health and disease by a mutually efficient and communicative exchange of Ca2+ between compartments. A coordination of the Ca2+ signal is evident in the development of Ca2+ release-activated Ca2+ (CRAC) entry, vital to lymphocyte activation and replenishing of the ER Ca2+ stores, where modest decreases in ER luminal Ca2+ induce sustained increases in cytosolic Ca2+ sourced from steadfast extracellular Ca2+ supplies. While protein sensors that transduce Ca2+ signals in the cytosol such as calmodulin are succinctly understood, comparative data on the ER luminal Ca2+ sensors is only recently coming to light with the discovery that stromal interaction molecules (STIMs) sense variations in ER stored Ca2+ levels in the functional regulation of plasma membrane Orai proteins, the major component of CRAC channel pores. Drawing from data on the role of STIMs in the modulation of CRAC entry, this review illustrates the structural features that delimit the functional characteristics of ER Ca2+ sensors relative to well known cytoplasmic Ca2+ sensors.

Crystal and molecular structure of 1-benzylphosphole by X-ray analysis (1973)

Molecular dimensions for the title compound have been established by single-crystal X-ray analysis from photographic data. Crystals are orthorhombic, space group Pbca with a= 17·62(2), b= 14·60(2), c= 7·67(1)Å, Z= 8. The structure was solved by the heavy-atom method and refined by full-matiix least-squares calculations to R 0·073 over 1351 independent observed reflexions. Comparison of the molecular dimensions with those of other heteroaromatic compounds is made. The phospholering has a non-planar geometry, and the mean P–C(phosphole) length of 1·783(5)Å is consistent with the interpretation that some electron delocalisation is present in the ring.
Physicians, Lenses, and Myopia (1990)

To the Editor. —The recent marketing of a new intraocular lens had a disturbing wrinkle that deserves comment. Several ophthalmologists sent the copyrighted advertising material in their mailings to patients and were associated in newspaper articles as designated surgeons for a given geographic area. What is wrong with this perceived alliance? The lens through which this issue must be viewed is an ethical lens, one that prevents professional myopia. If physicians align themselves with products (eg, companies), then patients have every right to question the fiduciary (trusting) relationship that our profession has had as one of its essential elements and from which we derive the societally given privilege of being a profession.1,2Loss of this fiduciary relationship will lead to deprofessionalization.3,4 The trust between physician and patient is critical and is being weakened by (among other factors) the technologic explosion. We do not need ophthalmologists adding to our
Speech Perception as a Function of Electrical Stimulation Rate: Using the Nucleus 24 Cochlear Implant System (2000)

For the speech processing strategy, implant system, and subjects evaluated in this study, the group results indicated that the use of electrical stimulation rates higher than 250 pps/ch (up to 1615 pps/ch) generally provided no significant improvement to speech comprehension. However, individual results indicated that perceptual benefits could be obtained by adjusting rate of stimulation optimally to suit each subject. Results from one subject, together with tinnitus problems arising from high-rate stimulation for another subject, indicated that high rates of stimulation may in fact be undesirable for some subjects.

A wavelength tunable Q-switched fiber laser using fiber Bragg gratings (1997)

This paper reports on a Q-switched Er-doped fiber laser using the stress dependence of a wavelength of reflected light from fiber Bragg gratings. The laser cavity consists of a 0.5-m-long Er-doped fiber and two fiber gratings (FG) attached at both ends of the fiber. The pump laser is a 1.48 μm semiconductor laser. Wavelength control of the reflected light from the FG was carried out by bending a metal rod to which the FGs were attached, or by applying stress to the FG using a piezoelectric transducer (PZT). Q-switching was carried out by changing the wavelength of the reflected light at high speed using the PZT. When the pump power was 26 mW and the repetition rate was 1 kHz, the optical pulse had a pulse width of 2.46 μs and a peak power of 2.1 mW. By adjusting the reflection from the FG, the oscillation wavelength was varied by 4 nm. The relationship among the reflection spectrum of the FG, the wavelength shift of the reflected light from the FG, the pump power, and the pulse width of the optical pulse was clarified. © 1998 Scripta Technica.

The rhodopsin–guanylyl cyclase of the aquatic fungus<i>Blastocladiella emersonii</i>enables fast optical control of cGMP signaling (2015)

Blastocladiomycota fungi form motile zoospores that are guided by sensory photoreceptors to areas of optimal light conditions. We showed that the microbial rhodopsin of Blastocladiella emersonii is a rhodopsin-guanylyl cyclase (RhGC), a member of a previously uncharacterized rhodopsin class of light-activated enzymes that generate the second messenger cyclic guanosine monophosphate (cGMP). Upon application of a short light flash, recombinant RhGC converted within 8 ms into a signaling state with blue-shifted absorption from which the dark state recovered within 100 ms. When expressed in Xenopus oocytes, Chinese hamster ovary cells, or mammalian neurons, RhGC generated cGMP in response to green light in a light dose-dependent manner on a subsecond time scale. Thus, we propose RhGC as a versatile tool for the optogenetic analysis of cGMP-dependent signaling processes in cell biology and the neurosciences.

Mannoheptulose has differential effects on fasting and postprandial energy expenditure and respiratory quotient in adult Beagle dogs fed diets of different macronutrient contents (2014)

The present study aimed to determine the effects of mannoheptulose (MH) (8 mg/kg) on energy expenditure (EE), respiratory quotient (RQ) and glycaemic response in healthy adult Beagle dogs (n 8; 9·62 (sem 0·31) kg; body condition score 4·5). The study was designed as replicated 4 × 4 Latin squares with a 2 × 2 factorial treatment structure. The dietary treatments were low carbohydrate (CHO) relative to fat diet (LC; 31 % CHO, 28 % fat) with placebo (0 mg/kg) or MH supplement and high CHO relative to fat diet (HC; 54 % CHO, 11 % fat) with placebo (0 mg/kg) or MH supplement. Dogs were fed to maintain body weight (HC and HC(+MH) 3625 (sem 295) kJ and LC and LC(+MH) 3542 (sem 284) kJ). Resting and postprandial (0-4 h; 5-10 h; 11-17 h; 18-23 h) EE and RQ were determined by indirect calorimetry (days 12 or 14). Glycaemic response to a meal (24 h) and plasma MH concentrations were determined on days 12 or 14. Plasma MH followed first-order kinetics, confirming that MH is absorbed and available to the animal. In the presence of high dietary CHO, MH increased postprandial EE (5-10 h only), suggesting MH increased dietary induced thermogenesis. In contrast to earlier reports, MH did not affect serum glucose or insulin in the present study. Irrespective of MH, dogs adapted RQ to diet composition and dogs consuming the LC diet had a greater incremental AUC for glucose, but not insulin, than dogs consuming the HC diet.
