Do non-steroidal anti-inflammatory drugs cause a delay in fracture healing? (2005)

A short cut review was carried out to establish whether there is any evidence that non-steroidal anti-inflammatory drugs (NSAIDs) might delay fracture healing. A total of 514 papers were found using the reported search, of which three represent the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these best papers are tabulated. At present, although there are theoretical concerns about the adverse effects of NSAIDs on fracture healing, there is not enough clinical evidence to deny patients with simple fractures their analgesic benefits.

Understanding Road Layout From Videos as a Whole (2020)

In this paper, we address the problem of inferring the layout of complex road scenes from video sequences. To this end, we formulate it as a top-view road attributes prediction problem and our goal is to predict these attributes for each frame both accurately and consistently. In contrast to prior work, we exploit the following three novel aspects: leveraging camera motions in videos, including context cues and incorporating long-term video information. Specifically, we introduce a model that aims to enforce prediction consistency in videos. Our model consists of one LSTM and one Feature Transform Module (FTM). The former implicitly incorporates the consistency constraint with its hidden states, and the latter explicitly takes the camera motion into consideration when aggregating information along videos. Moreover, we propose to incorporate context information by introducing road participants, e.g. objects, into our model. When the entire video sequence is available, our model is also able to encode both local and global cues, e.g. information from both past and future frames. Experiments on two data sets show that: (1) Incorporating either global or contextual cues improves the prediction accuracy and leveraging both gives the best performance. (2) Introducing the LSTM and FTM modules improves the prediction consistency in videos. (3) The proposed method outperforms the SOTA by a large margin.

Engineering mechanics : statics (1991)

Jong and Rogers have written an in depth text covering various topics of the first courses in statics and dynamics offered in the sophomore and junior year of engineering colleges. Students are assumed to have a background in algebra, geometry, trigonometry, and basic differential and integral calculus. Students with prior knowledge of college physics will have an added advantage for learning statics and dynamics. Mechanics has long been recognized as a deductive science. However, the learning process is largely inductive. In the text, simple topics and problems precede those that are more complex and advanced. The text is written to provide a clear and up-to-date presentation of the theory and application of engineering mechanics; It is aimed at helping engineering students develop an ability to apply well-established principles to analyze and solve problems in a logical and effective manner.
Catheter Ablation of Long-Lasting Accelerated Idioventricular Rhythm in a Patient with Mild Left Ventricular Dysfunction (2012)

A 35-year-old woman with long-lasting accelerated idioventricular rhythm (AIVR) exhibited palpitation and dyspnea on exertion and mild left ventricular (LV) dysfunction during followup. Symptoms appeared 10 years after the AIVR was first noted, and she underwent catheter ablation for curative therapy of AIVR after 12 years. Radiofrequency ablation of the anteroseptal site of the LV at the earliest activation terminated rhythm. An echocardiogram, taken 1 month after discharge, subsequently revealed that the left ventricular wall motion had normalized. This is a rare case of long-lasting AIVR with mild LV dysfunction.
Purification and Properties of a <scp>d</scp>‐Galactose/<i>N</i>‐Acetyl‐<scp>d</scp>‐ galactosamine‐Specific Lectin from <i>Erythrina cristagalli</i> (1982)

The lectin from the seeds of Erythrina cristagalli has been isolated in high yield (75 %) and homogeneous form by affinity chromatography on a column of D‐galactose‐derivatised Sepharose. It is a glycoprotein with a molecular weight of 56800±900 and s 20.w , = 3.9 S, composed of two subunits (apparent molecular weights of 28000 and 26000 respectively) both of which are glycosylated. The total carbohydrate content is 4.5% and it is comprised of mannose, N ‐acetylglucosamine, fucose and xylose in amounts corresponding to 7, 4, 2 and 2 mo1/56800 Da respectively. The amino acid composition of the lectin is characterised by a high content of acidic and hydroxy amino acids, low content of methionine and absence of cysteine. Valine is the only N‐terminal amino acid detected. The lectin is a metalloprotein in that it contains 0.093% Mn and 0.13percnt; Ca (1 mol and 1.9 mo1/56 800 Da respectively), both of which are tightly bound to the protein. E. cristagalli lectin agglutinates untreated human erythrocytes of all blood types, as well as rabbit erythrocytes, at a concentration of 5‐10 μg/ml. It is mitogenic for human peripheral blood T lymphocytes at an optimal concentration of about 100 pμg/ml, but is not mitogenic for mouse thymocytes or splenocytes. d ‐GahtOSe and various d ‐galactosides inhibit the hemagglutinating activity of the lectin. N ‐Acetyllactosarnine is most potent, completely inhibiting four agglutinating units of the lectin at 0.4 mM concentration. Lactose, N ‐acetyl‐ d ‐galactosamine and d ‐galactose are 5, 16 and 35 times less active respectively. Lactose specifically perturbs the ultraviolet spectrum of the lectin in the aromatic region. The difference spectrum obtained upon binding of the disaccharide to the lectin shows maxima at 291 nni and 282‐284 nm, indicating a change in the environment of tryptophan residues of the protein upon binding of sugar.
AN ALDOL-TYPE REACTION OF ACETONITRILES USING DIALKYLBORYL TRIFLATE (1982)

Validating system properties exhibited in execution traces (2007)

Execution traces produced by software systems during their operation can capture important runtime information, and thus are valuable sources for validating software functional properties. Automating the validation of such properties is currently achieved by writing test scripts, where most of the effort focuses on programming operations rather than specifying properties clearly. Improving this practice calls for domain-specific languages that can capture properties exhibited in traces at a higher abstract level.
A simple, compact, and rigid piezoelectric step motor with large step size (2009)

We present a novel piezoelectric stepper motor featuring high compactness, rigidity, simplicity, and any direction operability. Although tested in room temperature, it is believed to work in low temperatures, owing to its loose operation conditions and large step size. The motor is implemented with a piezoelectric scanner tube that is axially cut into almost two halves and clamp holds a hollow shaft inside at both ends via the spring parts of the shaft. Two driving voltages that singly deform the two halves of the piezotube in one direction and recover simultaneously will move the shaft in the opposite direction, and vice versa.
Digital state feedback control and feed-forward compensation for a parallel module DC-DC converter using the pole placement technique (2008)

In this paper, a simple digital control scheme for the parallel module converter is proposed using a digital state feedback control method. In this approach, the large signal average converter model is used to derive the robust tracking control algorithm of the state feedback controller instead of using the small signal modeling approach. The proposed control system can precisely achieve the interleaved current sharing and the output voltage regulation, and can achieve the systematical controller design for digital implementation using the pole placement technique. Also, a dynamic gain feed-forward control method using the operation point of the converter is proposed to improve the audio susceptibility. For a design example, a parallel module bus regulator system in the low-earth-orbit (LEO) satellite power system application, which has an input voltage step change, is implemented using a TMS320F2812 DSP.
Comparative evaluation of two different <i>Opuntia ficus‐indica</i> extracts for blood sugar lowering effects in rats (2010)

Stems of Opuntia ficus-indica (L.) Mill. (OFI) are traditionally used in Mexico to treat diabetes mellitus. Less research data are available for combinations of stem and fruit preparations. The present study was designed to investigate the effects of an aqueous extract prepared from the cladodes and a proprietary stem/fruit skin-blend (stem/fruit skin ratio 75/25) of OFI on blood glucose and plasma insulin in normal rats. A dose finding study with the traditional cladode OFI extract revealed that maximum effects on blood glucose and insulin were observed after oral administration in a dose range of 6-176 mg/kg. The proprietary OFI blend significantly lowered blood glucose levels in the glucose tolerance test to a similar extent (p < 0.05 vs control) as the traditional aqueous cladode extract when administered in a dose of 6 mg/kg. In contrast to the aqueous extract, the proprietary blend significantly increased basal plasma insulin levels (p < 0.01 vs control) indicating a direct action on pancreatic beta cells. The results suggest that both OFI extracts exert hypoglycemic activities in rats in doses as low as 6 mg/kg but that the effects of the proprietary stem/fruit blend were more pronounced in our model.
Requirement of the <i>galU</i> Gene for Polysaccharide Production by and Pathogenicity and Growth <i>In Planta</i> of <i>Xanthomonas citri</i> subsp. <i>citri</i> (2010)

Xanthomonas citri subsp. citri is the causal agent of citrus canker, which has a significant impact on citrus production. In this study, we characterized the galU gene of X. citri subsp. citri. Two galU mutants (F6 and D12) were identified in an X. citri subsp. citri EZ-Tn5 <R6Kgammaori/KAN-2> Tnp transposon library. Rescue cloning, sequence analysis, and Southern blot analysis indicated that both of these mutants had a single copy of the EZ-Tn5 transposon inserted in galU in the chromosome. Further study showed that galU was required for biosynthesis of extracellular polysaccharides (EPS; xanthan gum) and capsular polysaccharide (CPS) and biofilm formation. Mutation of galU resulted in a loss of pathogenicity for grapefruit. The loss of pathogenicity of a galU mutant resulted from its inability to grow in planta rather than from the effect on virulence genes. Quantitative reverse transcription-PCR assays indicated that mutation of galU did not impair the expression of key virulence genes, such as pthA of X. citri subsp. citri. Although D12 had a growth rate similar to that of the wild-type strain in nutrient broth, no D12 population became established in the intercellular spaces of citrus leaves. Coinoculation of a galU mutant with the wild-type strain did not promote growth of the galU mutant in planta. Defects in EPS and CPS production, pathogenicity, and growth in planta of the galU mutant were complemented to the wild-type level using plasmid pCGU2.1 containing an intact galU gene. These data indicate that the galU gene contributes to X. citri subsp. citri growth in intercellular spaces and is involved in EPS and CPS synthesis and biofilm formation.
Relationship between angiogenesis and prognosis of non-small cell lung cancer (2009)

Objective To investigate the relation between microvessel density(MVD) and vascular endothelial growth factor(VEGF) expression and the value of MVD and VEGF expression in non-small cell lung cancer(NSCLC).Methods MVD and VEGF expression in tumor tissue from 43 cases of NSCLC were examined by immunohistochemistry methods.Results The positive expression of VEGF in 43 patients with NSCLC was 53.5%(23/43),and it was significantly correlated with MVD count.MVD count had obvious relationship with NSCLC histology differentiation,TNM phage,lymphatic metastasis.The positive expressions of VEGF and MVD predicated shorter overall survival(OS).MVD was an independent prognostic factor of clinical outcome in NSCLC by multivariate analyses.The risk ratio of death was 34.247 fold of patients with MVD high expression compared with MVD lower expression(P0.01).Conclusions VEGF might play an important role in NSCLC angiogenesis.MVD is closely correlated with NSCLC metastasis and might be an independent prognostic factor,the higher MVD,the worse prognosis.

Real-time estimation of patterned wafer parameters using in situ spectroscopic ellipsometry (2003)

We analyze the problem of real-time thickness estimation for patterned wafers during an etching process using in situ spectroscopic ellipsometry. For that, a two-stage estimation algorithm is proposed. The first stage is an automatic model calibration algorithm that uses the data collected during an initial interval. The second stage is a nonlinear state estimation system designed for the tuned model. We study the sensitivity of this estimation strategy to variations in the wafer parameters and the process conditions.
Ferromagnetic resonance studies of very thin epitaxial single crystals of iron (1982)

Ferromagnetic resonance (FMR) has been used to study a wide variety of very thin single crystals of Fe grown on (110) GaAs substrates by molecular beam epitaxy. Data were taken at room and liquid nitrogen temperatures for films with thicknesses L in the range 18–200 Å. Due to surface anisotropy, the easy axis of the magnetization switches from [100] to [110] when L≤50 Å, independent of whether the the film surface is passivated by an Al-overcoat or has a thin Fe oxide surface layer. We suggest that this is an effective surface anisotropy arising in part from a depth dependent strain near the film-substrate interface. The changes in the parameters describing the angular dependence of the FMR spectra upon cooling to 77 K can be explained as due to magnetostriction arising from thermally induced strains plus the temperature dependence of the cubic volume anisotropy. The FMR linewidth is shown to be a linear function of frequency in the range 5–40 GHz.
El Profesional de Enfermería y el Alzheimer (2005)

El envejecimiento de la población de los países desarrollados, debido al aumento de la esperanza de vida y disminución de la natalidad hace que aumente la incidencia de patologías derivadas del envejecimiento, como la enfermedad de Alzheimer, patología degenerativa, de lenta evolución y sin cura, cuya asistencia necesita de diversos profesionales, entre los cuales, el Profesional de Enfermería tiene un peso específico desde la Atención Primaria y Especializada. Dada la dependencia originada por el Alzheimer, la atención global implica la asistencia no sólo del afectado, sino también de sus familiares y sobre todo de su cuidador principal. El Profesional de Enfermería realizará la práctica asistencial hacia el binomio enfermo – familiar, de acuerdo a las características personales de los mismos y a la fase evolutiva de la enfermedad de Alzheimer (Fase inicial, fase moderada, fase severa y fase terminal). Abstract The progressive increase in population aging in the developed countries, due to the increase in life expectancy and the decrease in natality causes that the incidence of pathologies derived from the aging like the disease of Alzheimer, degenerative pathology, of slow evolution and without solution increases at the same time. These pathologies needs the attention of several professionals, among them nurses have a special importance. Due to the dependence of Alzheimer patients on the global health system, the attendance must be directed not only to these patients but also to their relatives and especially to their main caregivers. Nurses will carry out their caring practice dedicated to the pair patient-relative, according to the personal characteristics or the phase of the Alzheimer disease (initial, severe and terminal) in which the patient is.

Perpendicular magnetic recording -- Evolution and future (1984)

This paper reviews research results for the head, medium and recording properties of a perpendicular recording system. Superior bit density characteristics obtained so far indicate that perpendicular recording is basically free from demagnetization in the high density region and that it will establish a new field of recording technology in the future. The prediction is explained in the context of complementary profiles of longitudinal and perpendicular recording. At the very beginning of magnetic recording, a perpendicular-type head was considered but abandoned because a suitable medium did not exist. Progress in material science has enabled us to develop a perpendicular recording medium which is very well suited for ultra high density recording. As so often happens, history has repeated itself through another study of perpendicular recording.
Purification and Characterization of Rad3 ATPase/DNA helicase from Saccharomyces cerevisiae (1989)

The Rad3 ATPase/DNA helicase was purified to physical homogeneity from extracts of yeast cells containing overexpressed Rad3 protein. The DNA helicase can unwind duplex regions as short as 11 base pairs in a partially duplex circular DNA substrate and does so by a strictly processive mechanism. On partially duplex linear substrates, the enzyme has a strict 5'----3' polarity with respect to the single strand to which it binds. Nicked circular DNA is not utilized as a substrate, and the enzyme requires single-stranded gaps between 5 and 21 nucleotides long to unwind oligonucleotide fragments from partially duplex linear molecules. The enzyme also requires duplex regions at least 11 base pairs long when these are present at the ends of linear molecules. Rad3 DNA helicase activity is inhibited by the presence of ultraviolet-induced photoproducts in duplex regions of partially duplex circular molecules.
Screening probiotic strains for safety: Evaluation of virulence and antimicrobial susceptibility of enterococci from healthy Chinese infants (2016)

The aim of this study was to evaluate the safety of enterococci isolated from Chinese infants and screen out potential probiotic candidates. One hundred eight strains were isolated from feces of 34 healthy infants, and 38 strains of Enterococcus spp. were categorized as follows: E. faecalis (22), E. faecium (10), E. hirae (3), E. durans (2), and E. casseliflavus (1). Of these, 72.7% of E. faecalis came from infants delivered by cesarean and 62.5% of E. faecium from infants delivered vaginally. For safety evaluation of strains, we determined presence of virulence genes; production of hemolysin, gelatinase, and biofilm; and antimicrobial susceptibility of enterococci. Six out of 14 virulence genes were detected with a distribution of gelE (26.3%), cylA (39.4%), esp (15.8%), efaA (63.2%), asa1 (50.0%), and ace (50.0%). In phenotype analysis, 36.8% of the strains exhibited positive hemolytic activity and 17.5% were positive for production of gelatinase. Results of antimicrobial susceptibility showed that different percentages of the strains were resistant to ciprofloxacin (5.2%), vancomycin (7.8%), rifampicin (10.5%), erythromycin (52.6%), and gentamycin (52.6%); remarkably, none of the strains were resistant to ampicillin or chloramphenicol. In total, 10 strains, including 6 E. faecium, which are free of virulence determinants and sensitive to common antimicrobial agents (e.g., ampicillin and vancomycin), were further assessed for their probiotic properties. All strains survived well in simulated gastric fluid and intestinal tract, with maximum reductions of 0.600 and 0.887 log cfu/mL, respectively. Six strains of E. faecium could resist 0.3 to 1.0% bile salt, of which E. faecium WEFA23 presented the highest growth (75.06%) at 1.0% bile salt. All strains showed bile salt hydrolase activity on glycodeoxycholic acid, but only 3 of E. faecium showed activity on taurodeoxycholic acid. These results deliver useful information on the safety of enterococci in infants in China, and provide a protocol to screen probiotics for absence of virulence and antimicrobial susceptibility of enterococci.
Enabling Low-Distortion Varactors for Adaptive Transmitters (2008)

A varactor diode configuration is presented for the implementation of low-distortion tunable matching networks, phase shifters, and filters. The configuration is based on varactors with an "exponential" C(V) relation in antiseries configuration with specific control voltage harmonic loading conditions. The resulting network combines a high capacitance tuning range with relatively low control voltages and excellent linearity. The linearity is independent of the applied control voltage and does not degrade at low tone spacing, which is ideal for the realization of adaptive transmitters and modulators. A specific N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> x-2 varactor doping profile is required for exact third-order intermodulation (IM3) cancellation. The remaining distortion is dominated by the much smaller fifth-order nonlinearities. The required impedance levels of the harmonic terminations are studied in terms of the maximum modulation bandwidth for which the proposed configuration remains linear. The doping profile optimization for quality factor, tuning range, and breakdown voltage is discussed. For experimental verification, the proposed varactor configuration has been implemented using a silicon-on-glass technology. The measurements demonstrate IM3 cancellation and indicate a superior linearity for modulated signals up to 10-MHz bandwidth.
