Insect Repellent (<i>N,N</i>-Diethyl-<i>m</i>-Toluamide) Cardiovascular Toxicity in an Adult (1993)

Adults, as well as children, are at risk for toxicity from insect repellents. The use of highly concentrated DEET-containing insect repellents should be avoided to reduce the risk of toxicity in both children and adults. The consequences of DEET toxicity are variable and unpredictable.
Apocynin increases glutathione synthesis and activates AP‐1 in alveolar epithelial cells (1999)

Apocynin (4-hydroxy-3-methoxy-acetophenone) is a potent intracellular inhibitor of superoxide anion production in neutrophils. In this study, we studied the effect of apocynin on the regulation of the antioxidant glutathione (GSH) and activation of the transcription factor AP-I in human alveolar epithelial cells (A549). Apocynin enhanced intracellular GSH by increasing gamma-glutamylcysteine synthetase activity in A549 cells. Apocynin also increased the expression of gamma-GCS heavy subunit mRNA. This was associated with increased AP-1 DNA binding as measured by the electrophoretic mobility shift assay. These data indicate that apocynin displays antioxidant properties, in part, by increasing glutathione synthesis through activation of AP-1.

En el presente trabajo se dilucida tal cuestion, con una particular referencia a la vigilancia de las comunicaciones telefonicas en la empresa y su problematica a la luz del delito de intervencion de comunicaciones privadas.
Stringlike Pulse Quantification Study by Pulse Wave in 3D Pulse Mapping (2012)

Integrating dPW and PPW can unify the classification of stringlike pulse including hypertensive stringlike pulse and spring stringlike pulse. Hence, the proposed novel method, PPW, enhances quantification of stringlike pulse.
The advantages of cell lysis before blood sample preparation by extraction for HPLC propofol analysis (2000)

Propofol (2,6-diisopropylphenol) is a short-acting drug with a large volume of distribution and high body clearance. It is suitable both for the induction of anaesthesia by bolus injection and the maintenance of anaesthesia by repeated injections or a continuous infusion. Examining the drug concentration its analysis in whole blood is recommended. This results from the fact that propofol molecules strongly bind with plasma proteins and cellular blood constituents and blood composition variations are observed between individuals or in different disease states or resulting from transfusion etc. In most cases the HPLC analysis follows the extraction of samples. The degree of propofol binding with blood cells can be different, depending on the blood type, and it can change in time, which may affect the results of the analysis. The paper discusses and shows the necessity of blood cell lysis before the extraction procedure. The cell lysis makes possible to determine the total amount of propofol in blood independently of the degree of propofol binding with cellular blood constituents and its changes.
Imams in the Netherlands Home-made Better than Import? (1999)

In February 1988, the Dutch government published a policy document on imams and their training. In previous years, it had strongly advocated such training. The policy document was the preliminary conclusion of a - sometimes heated - debate: Who is in control of future imams? Will the Dutch borders be closed to imams from Turkey and Morocco?
Abstracting Parallel Programming and Its Analysis Towards Framework Independent Development (2015)

Since the appearance of parallel processors and their rapid diversification across a broad spectrum, developers must phrase algorithms in a parallel manner using originally imperative and thus inappropriate high-level languages. Language extensions as well as highly complex debugging methods (e.g., profilers) to handle concurrent and non-deterministic execution are therefore continuously developed. Most tools, however, suffer from inflexibility and platform dependencies. Moreover, binary-instrumenting profilers involve high overhead, influencing and thus deforming the runtime behavior. This may even hide critical behavior, thus developers still rely on their experience and often manually include measures in their software-code (in-line profiling). In this work, we propose a platform independent abstraction layer enabling a unified parallelization and runtime-flexible choice of the actual parallelization framework (e.g., OpenMP, TBB). Based on a source-code aware point of view, we further introduce an automated in-line profiling methodology in order to allow an objective rating of the parallelization success. Moreover, we automatically extract runtime influencing aspects and exemplarily apply these methodologies to implementations of two different video-based driver-assistance algorithms consid ering two different processor types.
Perfusion mapping with multiecho multishot parallel imaging EPI (2007)

Echo-planar imaging (EPI) is the standard technique for dynamic susceptibility-contrast (DSC) perfusion MRI. However, EPI suffers from well-known geometric distortions, which can be reduced by increasing the k-space phase velocity. Moreover, the long echo times (TEs) used in DSC lead to signal saturation of the arterial input signal, and hence to severe quantitation errors in the hemodynamic information. Here, through the use of interleaved shot acquisition and parallel imaging (PI), rapid volumetric EPI is performed using pseudo-single-shot (ss)EPI with the effective T(*)(2) blur and susceptibility distortions of a multishot EPI sequence. The reduced readout lengths permit multiple echoes to be acquired with temporal resolution and spatial coverage similar to those obtained with a single-echo method. Multiecho readouts allow for unbiased R(*)(2) mapping to avoid incorrect estimation of tracer concentration due to signal saturation or T(1) shortening effects. Multiecho perfusion measurement also mitigates the signal-to-noise ratio (SNR) reduction that results from utilizing PI. Results from both volunteers and clinical stroke patients are presented. This acquisition scheme can aid most rapid time-series acquisitions. The use of this method for DSC addresses the problem of signal saturation and T(1) contamination while it improves image quality, and is a logical step toward better quantitative MR PWI.
Bevacizumab in the Treatment of Pterygium (2013)

Topical or subconjunctival bevacizumab was relatively safe and well tolerated, but it had no statistically significant effect on preventing pterygium recurrence. A large-scale trial with a suitable dosage and a longer follow-up would be required to rule out the possibility of any treatment benefit.
Aircraft Design Considerations to Meet One Engine Inoperative (OEI) Safety Requirements (2012)

Commercial airlines are obligated to operate such that an aircraft can suffer an engine failure at any point in its mission and terminate the flight without an accident. Only minimal aircraft damage is allowable, such as brake replacement due to very heavy application, or an engine inspection and/or possible removal due to use of an emergency rating. Such performance criteria are often referred to as zero exposure, referring to zero accident exposure to an engine failure. The critical mission segment for meeting one engine inoperative (OEI) criteria is takeoff. For a given weight, wind, and ambient condition, fixed wing aircraft require a balanced field length. This is the longer of the distance to take off if an engine fails at a predetermined critical point in the takeoff profile, or the distance to reject the takeoff and brake to a stop. Rotorcraft have requirements for horizontal takeoff procedures that are equivalent to a balanced field length requirements for fixed wing aircraft. Rotorcraft also perform vertical procedures where no runway or heliport distance is available. These were developed primarily for elevated heliports as found on oil rigs or rooftops. They are also used for ground level operations as might be found at heliports at the end of piers or other confined areas.
The Private Police (1999)

Legal scholars have largely neglected private policing, and the neglect is increasingly indefensible. The private security industry already employs more guards, patrol personnel and detectives than the federal, state and local governments combined, and the disparity is growing; to a striking extent, private firms now perform many of the beat-patrol tasks once thought central to the mission of the public police. This article describes what is known and unknown about the private security industry, traces the industry's history, assesses the challenges and opportunities it creates for judges and scholars, and provides an agenda for future research and doctrinal development. Private security firms furnish tangible evidence about what some people want but are not receiving from public law enforcement, and the legal regime governing private security -- deconstitutionalized, defederalized, tort-based, and heavily reliant both on legislatures and on juries -- offers important opportunities to test some of the most persistent proposals for reforming criminal procedure law. In addition, because maintaining order and controlling crime seem paradigmatic governmental functions, private policing presents a unique and underused vantage point for reexamining the public-private distinction and the state action doctrine. Finally, and perhaps most importantly, police privatization provides occasion for reconsidering the focus of constitutional law on negative obligations of government, and the focus of constitutional criminal procedure on fairness to individual criminal defendants; the dramatic spread of policing-for-hire should prompt us to rethink what it means to guarantee all citizens, regardless of wealth, the equal protection of the laws.
Observations on the nematicidal properties of some mycotoxins (1995)

Summary - Secondary metabolites produced by species of Fusarium and other soi! fW1gi were tested against sorne plant parasitic nematodes. Assays were conducted in vitTO using toxin concentrations of 0.02,0.2,2,20, and 200 ppm in 4 % methanol. T2-toxin, moniliforrnin, verrucarin A and cytochalasin B significanuy reduced the viability of Meloidogyne javanica juveniles at 2 ppm or higher concentrations after 72 hours exposure at 22.5 oc. Enniatin B showed a significant increase in M. javanica mortaliry at 20 ppm. T2-toxin also showed a nematicidal effect on M. hapla and Pratylenchus neglectus at 0.2 and 2 ppm, respectively. When tested in soi! against M. javanica parasitizing tomato plants, T2-toxin and moniliformin did not affect nematode densiry. In the treated pots a larger number of galls per g of root was a1so observed. Data suggest that mycotoxins can interact with nematodes through antagonistic or synergistic effects related to the concentration levels present in the plant rhizosphere.

Dynamic Reflection Phase and Polarization Control in Metasurfaces (2016)

Optical metasurfaces are two-dimensional optical elements composed of dense arrays of subwavelength optical antennas and afford on-demand manipulation of the basic properties of light waves. Following the pioneering works on active metasurfaces capable of modulating wave amplitude, there is now a growing interest to dynamically control other fundamental properties of light. Here, we present metasurfaces that facilitate electrical tuning of the reflection phase and polarization properties. To realize these devices, we leverage the properties of actively controlled plasmonic antennas and fundamental insights provided by coupled mode theory. Indium-tin-oxide is embedded into gap-plasmon resonator-antennas as it offers electrically tunable optical properties. By judiciously controlling the resonant properties of the antennas from under- to overcoupling regimes, we experimentally demonstrate tuning of the reflection phase over 180°. This work opens up new design strategies for active metasurfaces for displacement measurements and tunable waveplates.

Selective Projection Imaging: Applications to Radiography and NMR (1982)

Projection imaging has traditionally been plagued by intervening structures which limited the visibility of the desired regions. This problem was solved by the cross-sectional format of computerized tomography. This format, Manuscript received at 1982. however, exhibits relatively limited field of view, poor resolution and high dose. It is particularly unsuitable for the important problem of vessel imaging. In this paper we study selective projection imaging, a technique for isolating the desired structures in the projection format. In digital radiography, using temporal or energy subtraction, these techniques have shown excellent capability of imaging important structures. These techniques appear particularly applicable to NMR where, unlike the X-ray history, primarily cross-sectional images have been produced. In particular, because of its sensitivity to moving material, NMR appears ideally suited to vessel imaging. ntroduction.

Effects of coregistration of MR to CT images on MR stereotactic accuracy (1995)

Coregistration of different modality imaging serves to increase the ease and accuracy of stereotactic procedures. In many cases, magnetic resonance (MR) stereotaxis is supplanting computerized tomography (CT). The advantages of increased anatomical detail and multiplanar imaging afforded by MR, however, are offset by its potential inaccuracy as well as the more cumbersome and less available nature of its hardware. A system has been developed by one of the authors by which MR imaging can be performed separately without a stereotactic fiducial headring. Then, immediately prior to surgery, a stereotactic CT scan is obtained and software is used to coregister CT and MR images anatomically by matching cranial landmarks in the two scans. The authors examined this system in six patients as well as with the use of a lucite phantom. After initially coregistering CT and MR images, six separate anatomical (for the patients) and eight artificial (for the phantom) targets were compared. With coregistration, in comparison to CT fiducial scans, errors in each axis are less than or equal to 1 mm using the Cosman-Roberts-Wells system. In fact, the coregistered images are more accurate than MR fiducial images, in the anteroposterior (p = 0.001), lateral (p < 0.05), and vertical (p < 0.03) planes. Three-dimensional error was significantly less in the coregistered scans than the MR fiducial images (p < 0.005). The coregistration procedure therefore not only increases the case of MR stereotaxis but also increases its accuracy.
Enhancement of material ablation using 248, 308, 532, 1064 nm laser pulse with a water film on the treated surface (1995)

Many industrial laser processes, such as surface cleaning, require the removal of small thicknesses of matter, often on large samples. An experimental study has been performed in order to characterize and enhance the ablation of materials by means of the interaction between a pulsed laser beam and matter using common industrial laser sources, particularly at 248, 308, 532, and 1064 nm. Ablation was achieved on a static sample with one or several successive pulses and for different energy densities. These parameters enabled us to control the depth of the ablation in the micrometer range. Experiments have been carried out in ambient air, under gaseous cover, and then under a flowing water film on the material surface at atmospheric pressure. The material was a stainless-steel alloy. The experiments made it possible to determine the ablation fluence threshold for each wavelength and the alteration of the surface by the successive laser pulses. In order to avoid oxidation during the process, an argon gaseous medium was used, but peripheral oxide deposits always appeared and the efficiency of the ablation did not seem to increase. However, when the water flow on the surface was employed, the efficiency of the ablation increased by a factor of 2–15 for a certain incident power density. Peripheral oxide redeposition was absent using this method. Experiments have demonstrated that the confinement of the plasma within a transparent layer such as water at the given laser wavelength is an effective method for increasing ablation yield. This technique prevents the expansion of the plasma upstream of the target and the mechanical impulse communicated to the material increases. Calculation of ablated mass confirms that ablation yield could be increased by 15 for higher power densities. Similar results have been found using other materials such as alumina or silica. This means that this ablation technique can be employed in various types of industrial laser applications, for example, for cleaning oxidized surfaces or removing paint coatings.
Technical complications of implant-causes and management: A comprehensive review (2015)

Given the increasing popularity of dental implants, the number of failures due to late implant fracture is also expected to increase. Hence, the scope for prevention and management needs to be emphasized. The objective of this review article is to analyze the various causes of failure of dental implants due to implant fixture/abutment screw fractures and also to enumerate the management and the preventive options for these failures, thereby aiming to help the clinicians to properly plan the implant-supported prosthesis treatment by considering the important biomechanical aspects of this type of rehabilitation. The present review emphasizes the causes and management of technical complications and not the incidence of such complications.
Chemical requirements of feeding in rainbow trout, <i>Oncorhynchus mykiss</i> (Walbaum); palatability studies on amino acids, amides, amines, alcohols, aldehydes, saccharides, and other compounds (1990)

Past studies on palatability perception and the chemical requirements of feeding in rainbow trout have focused on the amino acids. The stimulatory effectiveness of other classes of compounds remains largely unknown. In the present study representative members from several chemical classes were tested for their palatability to rainbow trout. Three heretofore untested amino acids (L‐norvaline, L‐norleucine and c‐aminocaproic acid), three amides (acetamide, valeramide and caproic amide), two alcohols (hexanol and octanol) and four sugars (o‐ribose, o‐glucose, D‐fructose and sucrose) were all mildly to highly palatable substances at their highest concentration tested. All other compounds tested within these classes did not evoke a positive behavioural response, demonstrating that rainbow trout are selective in thosecompounds deemed as palatable. Moreover, all of the aldehydes, trimethylamine, pyrrolidine and all of the amines except the alcoholic derivative, ethanolamine, were without effect. A provisional scheme for relating chemical structure versus the perception of palatability in rainbow trout is presented.
Parallel research on KMP algorithm (2011)

The tradition pattern matching algorithm need backtrack and compare repeatedly, so that affects efficiency of algorithm. Knuth and others put forward KMP algorithm in order to promote efficiency of the pattern matching. Paralle KMP algorithm based on MPI is provided in this paper, which can get higher efficiency.
Spreadsheet Property Detection With Rule-assisted Active Learning (2017)

Spreadsheets are a critical and widely-used data management tool. Converting spreadsheet data into relational tables would bring benefits to a number of fields, including public policy, public health, and economics. Research to date has focused on designing domain-specific languages to describe transformation processes or automatically converting a specific type of spreadsheets. To handle a larger variety of spreadsheets, we have to identify various spreadsheet properties, which correspond to a series of transformation programs that contribute towards a general framework that converts spreadsheets to relational tables.
Direct sequence identification and kinetic analysis of an MHC class I-restricted <i>Listeria monocytogenes</i> CTL epitope. (1994)

Murine infection with the intracellular bacterium Listeria monocytogenes elicits MHC class I-restricted CTL with specificity for multiple bacterial peptides. The variety and relative abundance of self-peptides bound by MHC molecules make identification of pathogen-derived peptides difficult. In this report, the sequence of a pathogen-derived CTL epitope is determined by direct analysis of peptides extracted from MHC class I molecules. The epitope, p60 217-225, is presented to L. monocytogenes-specific CTL by the H-2Kd MHC class I molecule and is derived from p60, a secreted invasion-associated protein. Quantitation of p60 217-225 in infected cells shows that this epitope is detectable within 2 h of infection and, after a 9-h infection, there are over 3000 epitopes per infected cell. This contrasts with listeriolysin 91-99, the other major L. monocytogenes epitope, which is present in quantities below 200 epitopes per cell until 5 h of infection and reaches 800 epitopes per cell 9 h after infection. This report shows that identifying new T lymphocyte epitopes by direct sequence analysis of peptides isolated from MHC molecules is feasible. Furthermore, kinetic and quantitative analysis of T cell epitopes in infected cells is a useful approach to investigate the multispecific CTL response to complex intracellular pathogens.
