Impact of implant length and diameter on survival rates (2006)

When surgical preparation is related to bone density, textured-surfaced implants are employed, operators' surgical skills are developed, and indications for implant treatment duly considered, the survival rates for short and for wide-diameter implants has been found to be comparable with those obtained with longer implants and those of a standard diameter. The use of a short or wide implant may be considered in sites thought unfavourable for implant success, such as those associated with bone resorption or previous injury and trauma. While in these situations implant failure rates may be increased, outcomes should be compared with those associated with advanced surgical procedure such as bone grafting, sinus lifting, and the transposition of the alveolar nerve.
Adsorption of copper(II) and chromium(III) ions onto amidoximated cellulose (2000)

Chemical modification of cellulose powder is performed by successive reactions with acrylonitrile in an alkaline medium followed by aqueous hydroxylamine to prepare amidoximated cellulose. Due to complexation, the amidoxime groups immobilize heavy cations from buffered solutions at various pH values. The capacity of adsorption for Cu(II) and Cr(III) ions is related to the amount of amidoxime groups in the support and to the metal concentration of the polluted solution. The formation of a 1/1 complex is proved by the adsorption limit values. Desorption of the cations is possible by treatment with a stronger complexing agent such as ethylenediaminetetracetic acid. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 75: 1624–1631, 2000
Cloning and Functional Expression of cDNA Encoding Pheromone Δ9 Acyl‐CoA Desaturase of the Tobacco Cutworm, <i>Spodoptera litura</i> (Lepidoptera: Noctuidae) (2005)

ABSTRACT A cDNA encoding pheromone Δ9 acyl‐CoA desaturase, Slit KPSE was isolated from sex pheromone gland of the tobacco cutworm, Spodoptera litura which uses a diene unsaturated fatty acid (UFA) derivative, Z9E11‐14 : 2 as a major pheromone component. The fulllength open reading frame coding region of Slit KPSE was inserted in a yeast shuttle vector, YEpOLEX, and two kinds of yeast ( Saccharomyces cerevisiae ) mutant strains were transformed with the recombinant vector. In the desaturase‐deficient ole 1 strain, Slit KPSE expressed a complementary enzyme producing two kinds of diene UFAs, more 9–16 : 1 and less 9–18 : 1 at a ratio of 1 : 0.74 exhibiting a typical functional characteristics as one of the pheromone Δ9 acyl‐CoA desaturase lineage group, KPSE, but no Δ9 14C monoene was detectable because of too small amount of 14C saturated fatty acid precursor to be reliably used by Slit KPSE in the transformed cells. However, the another transformed yeast strain elo 1 which is deficient of elongase 1, an enzyme converting 14C to 16C hydrocarbon substrate, was supplemented with some myristic acid (14 : 0) in the medium, and produced a significant amount of 9–14 : 1 in due to a much enhanced level of the 14C substrate suggesting that Slit KPSE may be responsible for making the Δ9 double bond on the diene pheromone component.
Silver nanoparticles: preparation, characterization, and kinetics (2011)

In this paper we report the effect of aniline concentrations on the growth and size of silver nanocrystals using aniline and silver nitrate as reductant and oxidant, respectively. UV-Vis spectroscopy, transmission electron microscopy (TEM) and selected areas electron diffraction (SAED) have been employed to characterize silver nanoparticles. The TEM images show that silver nanocrystals are roughly spherical and of uniform particle size, and the average particle size is ca. 25 nm. A broad surface plasmon resonance band appears at 400 nm. The rings patterns are in good agreement with the standard values of the face-centered-cubic form of silver nanocrystals. This is attributed to the adsorption of aniline and /or interparticle interaction onto the surface of Ag-nanocrystals through electrostatic interactions between the lone-pairs electrons of –NH2 and positive surface of Ag- nanoparticles.
Microarray analysis of gene expression in the aging human retina. (2002)

Using commercially available slide microarrays, the authors show that aging of the human retina is associated with changes in patterns of gene expression. This analysis suggests that pathways involved in stress response and energy metabolism play key roles in retinal aging. These studies demonstrate the utility of gene microarrays in identifying global patterns of retinal gene expression and lay the foundation for future studies defining the genetic basis of aging-associated retinal diseases, such as age-related macular degeneration.
SoftSig: Software-Exposed Hardware Signatures for Code Analysis and Optimization (2009)

Many code analysis techniques for optimization, debugging, and parallelization must perform runtime disambiguation of address sets. Hardware signatures support such operations efficiently and with low complexity. SoftSig exposes hardware signatures to software through instructions that control which addresses to collect and which to disambiguate against. The Memoise algorithm demonstrates SoftSig's versatility by detecting and eliminating redundant function calls.
Parallel analog circuits for real time signal processing: Design and analysis (2003)

A network using resistors and active devices that implements a two-dimensional convolution whose shape is similar to a Gaussian is described. The network consists of resistive connections between each node and its nearest and second-nearest neighbors. When integrated on a CMOS chip with photoreception elements, the network forms a monolithic image reception and smoothing system with real-time response. The filter's width, which depends on the ratio of certain resistors, is continuously variable. Networks for other filter shapes are proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The yeast CLC chloride channel functions in cation homeostasis (1998)

A defect in the yeast GEF1 gene, a CLC chloride channel homolog leads to an iron requirement and cation sensitivity. The iron requirement is due to a failure to load Cu2+ onto a component of the iron uptake system, Fet3. This process, which requires both Gef1 and the Menkes disease Cu2+-ATPase yeast homolog Ccc2, occurs in late- or post-Golgi vesicles, where Gef1 and Ccc2 are localized. The defects of gef1 mutants can be suppressed by the introduction of Torpedo marmorata CLC-0 or Arabidopsis thaliana CLC-c and -d chloride channel genes. The functions of Gef1 in cation homeostasis provide clues to the understanding of diseases caused by chloride channel mutations in humans and cation toxicity in plants.
Transfusion‐free Surgery is a Treatment Plan for All Patients (1998)

Due to the increased risks associated with allogenic blood transfusion, blood management in surgical procedures, especially in orthopedic settings, should include reduction of perioperative blood loss. Preoperative nursing assessment will help define patients at increased risk for transfusion. Both nonpharmacologic and pharmacologic techniques can help minimize allogenic transfusion by reducing blood loss. One such method of managing anemia and reducing patient exposure to allogenic transfusion is the perioperative use of recombinant human erythropoietin--erythropoietin alfa--an innovative surgical blood management tool. Increased awareness by perioperative nurses of the use of erythropoietin alfa and patient implications can contribute to the overall blood conservation goal.
Overexpression of an R1R2R3 MYB Gene, <i>OsMYB3R</i>-<i>2</i>, Increases Tolerance to Freezing, Drought, and Salt Stress in Transgenic Arabidopsis (2007)

We used a cDNA microarray approach to monitor the expression profile of rice (Oryza sativa) under cold stress and identified 328 cold-regulated genes. Thirteen such genes encoding MYB, homeodomain, and zinc finger proteins with unknown functions showed a significant change in expression under 72-h cold stress. Among them, OsMYB3R-2 was selected for further study. Unlike most plant R2R3 MYB transcription factors, OsMYB3R-2 has three imperfect repeats in the DNA-binding domain, the same as in animal c-MYB proteins. Expression of OsMYB3R-2 was induced by cold, drought, and salt stress. The Arabidopsis (Arabidopsis thaliana) transgenic plants overexpressing OsMYB3R-2 showed increased tolerance to cold, drought, and salt stress, and the seed germination of transgenic plants was more tolerant to abscisic acid or NaCl than that of wild type. The expression of some clod-related genes, such as dehydration-responsive element-binding protein 2A, COR15a, and RCI2A, was increased to a higher level in OsMYB3R-2-overexpressing plants than in wild type. These results suggest that OsMYB3R-2 acts as a master switch in stress tolerance.

TRAFFIC DATA LOGICAL DETECTION BY INFRARED SENSOR ARRAY (1993)

Traffic data used as feedback information are required for operations of highway systems such as planning, desing, construction, maintenance, evaluation, and management. Reliable collection of traffic data has become a basic issue. Vehicle detectors have been in use for over 50 years. Typical applications of an infrared beam sensor array are identification of two-way vehicle movement, including volume, speed, speed profile, gap distribution, etc. The difficulty in such application is to develop a logical model to identify traffic in two opposing directions by an infrared beam sensor array. A study has been conducted to develop infrared beam sensor array detection techniques and logical models for identification of traffic movement.

Arabidopsis <i>dth9</i> Mutation Identifies a Gene Involved in Regulating Disease Susceptibility without Affecting Salicylic Acid–Dependent Responses (2000)

To determine which components of the plant defense response make important contributions to limiting pathogen attack, an M(2) mutagenized population of a transgenic Arabidopsis line was screened for mutants showing constitutive expression of beta-glucuronidase activity driven by the promoter region of the CEVI-1 gene. The CEVI-1 gene originally was isolated from tomato plants and has been shown to be induced in susceptible varieties of tomato plants by virus infection in a salicylic acid-independent manner. We report here the characterization of a recessive mutant, detachment9 (dth9). This mutant is more susceptible to both virulent and avirulent forms of the oomycete Peronospora and also exhibits increased susceptibility to the moderately virulent bacterial pathogen Pseudomonas syringae pv maculicola ES4326. However, this mutant is not affected in salicylic acid metabolism and shows normal expression of pathogenesis-related (PR) genes after pathogen attack. Furthermore, after inoculation with avirulent pathogens, the dth9 mutant shows a compromised systemic acquired resistance response that cannot be complemented by exogenous application of salicylic acid, although this molecule is able to promote normal activation of PR genes. Therefore, the dth9 mutation defines a regulator of disease susceptibility that operates upstream or independently of salicylic acid. Pleiotropy is also evident in the dth9 mutant in the sense that the shoots of dth9 plants are insensitive to the exogenously applied auxin analog 2,4-dichlorophenoxyacetic acid.
Interpreting Microbial Biosynthesis in the Genomic Age: Biological and Practical Considerations (2017)

Genome mining has become an increasingly powerful, scalable, and economically accessible tool for the study of natural product biosynthesis and drug discovery. However, there remain important biological and practical problems that can complicate or obscure biosynthetic analysis in genomic and metagenomic sequencing projects. Here, we focus on limitations of available technology as well as computational and experimental strategies to overcome them. We review the unique challenges and approaches in the study of symbiotic and uncultured systems, as well as those associated with biosynthetic gene cluster (BGC) assembly and product prediction. Finally, to explore sequencing parameters that affect the recovery and contiguity of large and repetitive BGCs assembled <i>de novo</i>, we simulate Illumina and PacBio sequencing of the <i>Salinispora tropica</i> genome focusing on assembly of the salinilactam (<i>slm</i>) BGC.
Photoelectrochemistry (1980)

The electron-hole pair formation that occurs at the interface between a semiconductor and a solution upon absorption of light leads to oxidation or reduction reactions of solution species. The principles of such photodriven processes are described as well as applications of semiconductors in electrochemical cells and as particulate systems for carrying out heterogeneous photocatalysis and photoelectrosynthesis.
[Relation between the dosage of methimazole and its intrathyroidal concentrations]. (1991)

Intrathyroidal concentrations of methimazole (MMI) were measured by means of high-performance liquid chromatography in 46 patients with Graves' disease who had undergone thyroidectomy. In this experiment, the dose of the drug varied from 5 mg/day to 40 mg/day, and the interval between the last dose and surgery ranged from 2 to 26 hours, and the mode of drug administration varied from a single dose to four divided doses. With dose of MMI from 5 to 15 mg/day, intrathyroid levels of MMI increased with increasing dose, but without significant increase when the dose was above 15 mg/day. There was no difference between patients taking the drug in divided doses and those taking it in one single dose of the same amount, or between patients taking the final dose 2 hours before thyroid excision aud those taking it 26 hours before excision. Our results indicate a saturable uptake mechanism for MMI by the thyroid, and MMI 15 mg/day is the most satisfactory dose for treating hyperthyroidism. The intrathyroidal concentrations are maintained for 26 hours at least, and the single daily dose of MMI is effective and reasonable for treatment of Graves' disease.
Low power accelerometer based intrusion and tamper detector (2014)

In this paper a novel sensor is proposed, which can be applied both to intrusion detection or tamper detection purposes. The device senses vibrations caused by the attacker, using MEMS accelerometers, to provide alarm signals. The sensor uses low duty cycling operation to conserve its energy, thus it is suitable for wireless applications. The performance of the sensor is illustrated with real measurements.
Effects of various encapsulating films on laser recrystallization of silicon on SiO2 (1982)

Single-crystal silicon-on-oxide was produced by laser recrystallization of a 0.6-μm polysilicon film deposited on 1 μm of thermal SiO2. Oriented growth commenced where the polysilicon film was in contact with the silicon substrate, and proceeded laterally over the fully recessed SiO2. Typical dimensions of the single-crystal silicon-on-oxide film are 25 μm by 7 mm. The laser annealing was done with several different encapsulating films above the polysilicon, including 11.0, 16.4, and 32.9 nm of Si3N4, 25 nm of SiO2, 25 nm SiO2 +32.9 nm Si3N4, and uncapped samples. In addition, samples were laser annealed with and without an 1100 °C N2 preanneal of the structure. The 1100 °C anneal reduced the nucleation of misoriented grains in all samples, and extended the range of useable powers for the Si3N4 capped samples. The 32.9-nm Si3N4 cap produced the smoothest film and the most efficient coupling of the laser light into the silicon. The maximum distance of single-crystal growth was the same for all nitrogen-annealed samples, and showed a weak dependence on the melt width induced by the beam used for recrystallization. TEM micrographs of the recrystallized silicon show that the defects lie predominantly in the 110 direction. Their density increases away from the seed region, and they coalesce to form the grain boundaries at the transition to polysilicon growth.
A video-based lane keeping assistant (2000)

We propose a lane keeping assistance system which warns the driver of unintended lane departures. Based on an existing robust video-based lane detection algorithm we compare different methods to detect lane departure. A number of assumptions on driver behaviour in certain situations have been integrated to distinguish between intended and unintended lane departures. We integrated our lane keeping assistant in an experimental car and performed systematic experiments in real traffic situations.
Solid Molecular Dispersions of Itraconazole for Enhanced Dissolution and Controlled Drug Delivery (2010)

The purpose of this study was to investigate the formation of solid molecular dispersions of Itraconazole (ITZ) in a number of glassy polymers including PVP, crospovidone, PVP-EC, HPMCAS and HPMCAS-PEO to enhance its dissolution and achieve release control. Polarizing light microscopy was found to be more sensitive than DSC and XRD for detecting crystallinity. PVP, PVP-EC & crospovidone generated loading levels of ~20%, substantially greater than that of HPMCAS and HPMCAS-PEO (5%). The loaded ITZ was stabilized though molecular interactions with the polymer and reduced molecular mobility in a glassy polymer matrix. Overall, immediate release was achieve d using PVP and crospovidone, enteric delivery provided by HPMCAS, and controlled release generated with EC and PEO. Among all polymers studied, only ITZ in PVP failed to generate sufficient stability in the presence of moisture. In general, solid molecular dispersion is a useful approach to improve the poor solubility and bioavailability of Itraconazole.
Metaclasses are first class: The ObjVlisp Model (1987)

This paper shows how an attempt at a uniform and reflective definition resulted in an open-ended system supporting ObjVlisp, which we use to simulate object-oriented language extensions.We propose to unify Smalltalk classes and their terminal instances. This unification allows us to treat a class as a “first class citizen”, to give a circular definition of the first metaclass, to access to the metaclass level and finally to control the instantiation link. Because each object is an instance of another one and because a metaclass is a real class inheriting from another one, the metaclass links can be created indefinitely.This uniformity allows us to define the class variables at the metalevel thus suppressing the Smalltalk-80 ambiguity between class variables and instance variables: in our model the instance variables of a class are the class variables of its instances.
Mapping pilicide anti-virulence effect in Escherichia coli, a comprehensive structure–activity study (2012)

Pilicides prevent pili formation and thereby the development of bacterial biofilms in Escherichia coli. We have performed a comprehensive structure activity relationship (SAR) study of the dihydrothiazolo ring-fused 2-pyridone pilicide central fragment by varying all open positions. Orthogonal projections to latent structures discriminant analysis (OPLS-DA) was used to distinguish active from inactive compounds in which polarity proved to be the most important factor for discrimination. A quantitative SAR (QSAR) partial least squares (PLS) model was calculated on the active compounds for prediction of biofilm inhibition activity. In this model, compounds with high inhibitory activity were generally larger, more lipophilic, more flexible and had a lower HOMO. Overall, this resulted in both highly valuable SAR information and potent inhibitors of type 1 pili dependent biofilm formation. The most potent biofilm inhibitor had an EC(50) of 400 nM.
