Expression of vascular endothelial growth factor in sera and lymph nodes of the plasma cell type of Castleman's disease (1999)

To evaluate the possible involvement of vascular endothelial growth factor (VEGF) in the pathogenesis of Castleman's disease, we studied VEGF levels in sera and supernatants of cultured lymph nodes from two patients with the plasma cell type of Castleman's disease, and analysed the expression of VEGF immunohistochemically in the lymph nodes. Clinically, one patient was classified as the localized type and the other as the multicentric type. Histologically, mature plasma cells and hyalinized vessels were prominent in the interfollicular region. The VEGF levels of the sera and the supernatants of cultured lymph nodes of both patients were higher than those of normal controls. VEGF was strongly expressed in plasma cells in the interfollicular region of the lymph nodes of both patients, but rarely in normal lymph nodes. Our results suggest that VEGF may be involved in the marked vascular proliferation in the interfollicular region of the lymph nodes of the plasma cell type of Castleman's disease.
A new technique for low-angle radar tracking (2002)

Results obtained from both simulation and experimental data are presented to show that the technique is effective and robust in terms of providing accurate estimates of target heights.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A glimpsing model of speech perception in noise (2006)

Do listeners process noisy speech by taking advantage of "glimpses"-spectrotemporal regions in which the target signal is least affected by the background? This study used an automatic speech recognition system, adapted for use with partially specified inputs, to identify consonants in noise. Twelve masking conditions were chosen to create a range of glimpse sizes. Several different glimpsing models were employed, differing in the local signal-to-noise ratio (SNR) used for detection, the minimum glimpse size, and the use of information in the masked regions. Recognition results were compared with behavioral data. A quantitative analysis demonstrated that the proportion of the time-frequency plane glimpsed is a good predictor of intelligibility. Recognition scores in each noise condition confirmed that sufficient information exists in glimpses to support consonant identification. Close fits to listeners' performance were obtained at two local SNR thresholds: one at around 8 dB and another in the range -5 to -2 dB. A transmitted information analysis revealed that cues to voicing are degraded more in the model than in human auditory processing.
Lexical Generalization in CCG Grammar Induction for Semantic Parsing (2011)

We consider the problem of learning factored probabilistic CCG grammars for semantic parsing from data containing sentences paired with logical-form meaning representations. Traditional CCG lexicons list lexical items that pair words and phrases with syntactic and semantic content. Such lexicons can be inefficient when words appear repeatedly with closely related lexical content. In this paper, we introduce factored lexicons, which include both lexemes to model word meaning and templates to model systematic variation in word usage. We also present an algorithm for learning factored CCG lexicons, along with a probabilistic parse-selection model. Evaluations on benchmark datasets demonstrate that the approach learns highly accurate parsers, whose generalization performance benefits greatly from the lexical factoring. 1

Qui possède les médias (2017)

Qui possède les médias ? Il s’avère extraordinairement difficile de répondre à cette question simple. En France, l’ordonnance du 26 août 1944 du Conseil National de la Résistance rendait obligatoire – entre de multiples autres règles – la publication sur chaque exemplaire de journaux du nom des actionnaires et de leur profession. Ces règles n’ont, de fait, jamais été appliquées. Il est plus important que jamais d’améliorer les connaissances de la structure de l’actionnariat des médias d’information politique et générale. L’objectif de cette recherche est de mettre à jour, pour l’ensemble des médias d’information, la liste de leurs actionnaires ainsi que le secteur d’activité de ces derniers. Ce Policy Brief se concentre sur les cas de la France et de l’Espagne. Pour ces derniers, nous montrons que l’actionnariat des médias d’information se caractérise par sa complexité et son manque de transparence. De plus, une large part des actionnaires privés des médias tire l’essentiel de leurs ressources d’activités financières et d’assurance. En France, 51% des actionnaires des médias sont dans ce cas ; ils sont ainsi près de trois fois plus nombreux que les actionnaires issus du secteur de l’information et de la communication (18%). Au-delà de l’élargissement à d’autres pays, la prochaine étape logique de cette recherche consistera à mesurer l’impact de la structure de l’actionnariat sur la couverture médiatique.
Discrimination of Transient Signals Having Identical Energy Spectra (1970)

Pairs of waveforms having identical energy spectra were generated using a technique developed by Huffman [IRE Trans. IT8, S10–S16 (1962)]. A pair of such waveforms differ only in their phase spectra. The discriminability of such waveforms was measured under various conditions. The total duration of the waveforms was varied as well as the nature of the differences in their phase spectra. The results of these experiments suggest that the ear can discriminate differences in temporal order as small as 2.5 msec. In later experiments this discriminability among pairs was studied when both waveforms were partially masked by noise. Some pairs can be discriminated when only 6 dB above their masked threshold.
Clinical characteristics of 2019 novel coronavirus infection in China (2020)

Abstract Background Since December 2019, acute respiratory disease (ARD) due to 2019 novel coronavirus (2019-nCoV) emerged in Wuhan city and rapidly spread throughout China. We sought to delineate the clinical characteristics of these cases. Methods We extracted the data on 1,099 patients with laboratory-confirmed 2019-nCoV ARD from 552 hospitals in 31 provinces/provincial municipalities through January 29 th , 2020. Results The median age was 47.0 years, and 41.90% were females. Only 1.18% of patients had a direct contact with wildlife, whereas 31.30% had been to Wuhan and 71.80% had contacted with people from Wuhan. Fever (87.9%) and cough (67.7%) were the most common symptoms. Diarrhea is uncommon. The median incubation period was 3.0 days (range, 0 to 24.0 days). On admission, ground-glass opacity was the typical radiological finding on chest computed tomography (50.00%). Significantly more severe cases were diagnosed by symptoms plus reverse-transcriptase polymerase-chain-reaction without abnormal radiological findings than non-severe cases (23.87% vs. 5.20%, P <0.001). Lymphopenia was observed in 82.1% of patients. 55 patients (5.00%) were admitted to intensive care unit and 15 (1.36%) succumbed. Severe pneumonia was independently associated with either the admission to intensive care unit, mechanical ventilation, or death in multivariate competing-risk model (sub-distribution hazards ratio, 9.80; 95% confidence interval, 4.06 to 23.67). Conclusions The 2019-nCoV epidemic spreads rapidly by human-to-human transmission. Normal radiologic findings are present among some patients with 2019-nCoV infection. The disease severity (including oxygen saturation, respiratory rate, blood leukocyte/lymphocyte count and chest X-ray/CT manifestations) predict poor clinical outcomes.
Sensitivity of <i>Hartmannella</i> ( <i>Acanthamoeba</i> ) to <i>5</i> -fluorocytosine, hydroxystilbamidine, and other substances (1970)

The effect of 24 anti-amoebic and other chemotherapeutic compounds on six strains of hartmannellid amoebae was studied by tissue culture, agar diffusion, and liquid axenic culture. Of the recognized anti-amoebic compounds only one inhibited growth of the amoebae, which were remarkable for their resistance. Two compounds, hydroxystilbamidine isethionate and 5-fluorocytosine, showed some amoebicidal activity while some others were inhibitory.
An open-ended data representation model for EU_LISP (1988)

The goal of this paper is to describe an open-ended type system for Lisp with explicit and full control of bit-level data representations. This description uses a reflective architecture based on a metatype facility. This low-level formalism solves the problem of an harmonious design of a class taxononomy inside a type system.
Hepatic Storage of Glycosaminoglycans in Feline and Canine Models of Mucopolysaccharidoses I, VI, and VII (1992)

Livers from normal cats and dogs, cats with mucopolysaccharidoses (MPS) I and VI, and dogs with MPS VII were analyzed biochemically and morphometrically to determine the lysosomal storage of glycosaminoglycans (GAG) in these animal models of human genetic disease. Analyses were performed on liver samples from seven normal cats ranging in age from 13 weeks to 15 months; six MPS I-affected cats ranging in age from 10 weeks to 26 months; four MPS VI-affected cats ranging in age from 9 months to 32 months; four normal dogs ranging in age from 1 month to 47 months; and three MPS VII-affected dogs, 5 days, 11 days, and 14 months of age. All of the animals were from the breeding colony at the University of Pennsylvania School of Veterinary Medicine and were maintained in accordance with national standards for the care and use of laboratory animals. Each GAG subclass was quantitated, and total GAG concentration was determined. Liver from cats with MPS I had the highest total GAG concentration (5.7 times that of the control), followed by liver from dogs with MPS VII (1.8 times) and cats with MPS VI (1.5 times). These data were very closely correlated (R2 = 0.982) with the results of the morphometric analyses of hepatocyte and Kupffer cell vacuolation associated with lysosomal storage and support the validity of both methods. This is particularly important for the quantification of total and individual GAG concentrations in tissue preparations. The values obtained should prove useful in future assessments of therapeutic regimes, such as enzyme replacement, bone marrow transplantation, and gene therapy, for these genetic diseases.
MicroRNA profiling of Barrett's oesophagus and oesophageal adenocarcinoma (2010)

Expression of miRNA might define disease states in oesophageal epithelium. Dysregulation of specific miRNAs could contribute to metaplastic and neoplastic processes in the oesophageal mucosa.
Platelet/endothelial cell adhesion molecule-1 (CD31)-mediated cellular aggregation involves cell surface glycosaminoglycans (1993)

Platelet/endothelial cell adhesion molecule-1 (PECAM-1, CD31) is a 130-kDa integral membrane glycoprotein expressed on endothelial cells, platelets, and leukocytes. Experiments analyzing the aggregation of mouse L-cells stably transfected with full-length PECAM-1 cDNA have demonstrated that PECAM-1 is capable of mediating calcium-dependent heterophilic aggregation. In this report the ligand interactions involved in the aggregation process were studied. This aggregation was inhibited by heparin and chondroitin sulfate, but not by other glycosaminoglycans. Enzymatic removal of cell surface glycosaminoglycans confirmed a PECAM-1-glycosaminoglycan interaction and suggested that this interaction involved glycosaminoglycans on adjacent cells. PECAM-1 contains a glycosaminoglycan consensus binding sequence in the second immunoglobulin-like domain of the molecule's extracellular domain. A comparable region in the related adhesion protein N-CAM has been shown to mediate the adhesive properties of N-CAM. Cells expressing mutant PECAM-1 protein missing the second domain failed to aggregate. Synthetic peptides mimicking the consensus glycosaminoglycan binding sequence, L-K-R-E-K-N, inhibited aggregation. These results demonstrate that PECAM-1-mediated aggregation is dependent on the binding of PECAM-1 to specific glycosaminoglycans on adjacent cells via a glycosaminoglycan consensus binding sequence in the second immunoglobulin-like homology domain.
5-HT in the dorsal raphe nucleus is involved in the effects of 100-Hz electro-acupuncture on the pain-depression dyad in rats (2017)

The pain-depression dyad is becoming widespread in the clinic and is attracting increasing attention. A previous study by our group found that 100-Hz electro-acupuncture (EA), but not 2-, 50- and 2/100-Hz EA, was effective against the reserpine-induced pain-depression dyad. This finding is in contrast to the fact that low-frequency EA is commonly used to treat supraspinal-originating diseases. The present study aimed to investigate the mechanism underlying the effects of 100-Hz EA on the pain-depression dyad. Repeated reserpine injection was found to induce allodynia and depressive behaviors in rats. It decreased 5-hydroxytryptamine (5-HT) levels and immunoreactive expressions in the dorsal raphe nucleus (DRN). 100-Hz EA alleviated the pain-depression dyad and upregulated 5-HT in the DRN of reserpine-injected rats. Intracerebroventricular injection of para-chlorophenylalanine, an inhibitor of 5-HT resynthesis, suppressed the upregulation of 5-HT in the DRN by 100-Hz EA and partially counteracted the analgesic and anti-depressive effects of 100-Hz EA. The present study was the first to demonstrate that 5-HT in the DRN is involved in mediating the analgesic and anti-depressive effects of 100-Hz EA on the pain-depression dyad. This finding provided a scientific basis for high-frequency EA as a potential treatment for the pain-depression dyad.
Apoptosis in endometrial glandular and stromal cells in women with and without endometriosis (2001)

Spontaneous apoptosis is decreased in the endometrial glands in women with endometriosis, especially during late secretory/menstrual and early proliferative phases of the cycle. This may indicate increased viability of endometrial cells shed during menses, facilitating their ectopic survival and implantation.
DNA analysis technologies and their application to the medical field. (2001)

The human genome project has been successfully carried out and the draft sequence of the human genome has been clarified. The next step is to understand gene functions and to use the genome information in various fields including the biomedical field. As the genetic characteristics are dependent on SNPs, the development of a rapid, inexpensive and high throughput SNP analysis method is required. As the one base difference has to be analyzed in the SNP analysis, the simple hybridization assay can not be used. Besides a high throughput DNA sequencer and DNP chips, various methods and instruments have been developed for SNP analysis. They include the probe array assays with color-coded beads and bioluminometric assays such as Pyrosequencing and BAMPER (Bioluminometric Assay with Modified Primer Extension Reaction). It is demonstrated that BAMPER is very promising for realizing an inexpensive, cost effective and easy to use SNP typing method from the viewpoint of clinical diagnostics.
Imagine: media processing with streams (2001)

The power-efficient Imagine stream processor achieves performance densities comparable to those of special-purpose embedded processors. Executing programs mapped to streams and kernels, a single Imagine processor is expected to have a peak performance of 20 gflops and sustain 18.3 gops on mpeg-2 encoding.
Robotic systems in orthopaedic surgery (2011)

Robots have been used in surgery since the late 1980s. Orthopaedic surgery began to incorporate robotic technology in 1992, with the introduction of ROBODOC, for the planning and performance of total hip replacement. The use of robotic systems has subsequently increased, with promising short-term radiological outcomes when compared with traditional orthopaedic procedures. Robotic systems can be classified into two categories: autonomous and haptic (or surgeon-guided). Passive surgery systems, which represent a third type of technology, have also been adopted recently by orthopaedic surgeons. While autonomous systems have fallen out of favour, tactile systems with technological improvements have become widely used. Specifically, the use of tactile and passive robotic systems in unicompartmental knee replacement (UKR) has addressed some of the historical mechanisms of failure of non-robotic UKR. These systems assist with increasing the accuracy of the alignment of the components and produce more consistent ligament balance. Short-term improvements in clinical and radiological outcomes have increased the popularity of robot-assisted UKR. Robot-assisted orthopaedic surgery has the potential for improving surgical outcomes. We discuss the different types of robotic systems available for use in orthopaedics and consider the indication, contraindications and limitations of these technologies.
TRICEPS SURAE SYNDROME IN CEREBRAL PALSY (1954)

THE PURPOSE of this paper is threefold: first, to stimulate interest and to reevaluate the over-all problem and the need of early surgery in the care of the cerebral palsied child; second, to discuss the various functional disturbances associated with the spastic or tense triceps surae muscle, and third, to describe a surgical procedure directed at restoring control of the function of this muscle and correction of some of the bizarre deformities resulting from its involvement. During the past decade or more, repeated emphasis on so-called conservative therapy has overshadowed the surgical needs of the patients afflicted with cerebral palsy. During this period, with the exception of McCarroll's instructional course papers,<sup>1</sup>there has been little written on surgery in these children, and no satisfactory operative procedures worthy of the name new has been described. This apparent lack of attention on the part of the orthopedists to a universal problem

Time dependence of Rydberg EIT in pulsed optical and RF fields (2020)

Abstract We investigate the time dependence of atom-light and atom-RF field interactions in Rydberg electromagnetically-induced transparency (EIT) in a room-temperature and heated vapour cell. Quantum-optical transients are observed with rapid onset and dissolution of EIT induced by coupler-light pulses. The formulation and dissolution times of EIT, transient signals, and their dependencies on light intensities and Rydberg-atom density are studied. Simulations of pulsed EIT are performed by solving a time-dependent three-level master equation, whose results are in excellent agreement with experimental observations, including accurately reproducing quantum-optical transients observed at both onset and dissolution. We explore the time-dependent response of EIT to RF fields resonant with a Rydberg–Rydberg transition. An upper limit to the fundamental atom-RF field response time and instantaneous RF detection bandwidth with EIT-based sensors and receivers is established.
Mechanical Properties of Soy Protein-polyethylene Ribbon and Film Extrudates (1996)

Selected mechanical properties of chemically modified soy protein isolate (MSPI), polyethylene oxide (PEO), and low density polyethylene (LDPE) extrudates were studied. MSPI and PEO (50:50, w:w) were extruded initially to achieve a homogeneous mix and enhance their compatibility with LDPE. The ground MSPI-PEO extrudates were blended with 25, 50, 75, and 100% LDPE and extruded through a ribbon die. Protein concentrations in the ribbon extrudates ranged from 0 to 37.5%. Films were blown using MSPI-PEO-LDPE mixtures containing 0 to 8% protein. No significant crosslinking was found between MSPI and PEO, when 10, 25, 50% MSPI was extruded with PEO. Solubility of MSPI in the extrudates decreased significantly with increasing amounts of LDPE. Tensile strengths (TS) of ribbon extrudates ranged from 0.54 to 4.65 MPa and TS of film extrudates ranged from 2.43 to 12.56 MPa. Similarly, elongation (E) at break of ribbon extrudates decreased from 271 to 15%, and E of film extrudates decreased from 281 to 100% with the addition of protein.
Photochemical iron(III)-mediated autoxidation of dextromethorphan. (1989)

The photochemical reaction of dextromethorphan 1, a widely used anti-tussive drug, in hydrochloric acid and in the presence of iron(III) salts leads to the 10β-hydroxyderivative 3 as a major product in addition to the 10-ketoderivative 2. The product composition of this reaction is strongly dependent on the experimental conditions and the effects of solvents are presented.
Some consideration of the errors of brightness and two-colour types of spectral radiation pyrometer (1954)

Expressions are derived for the errors of the two types and from them a chart, from which these errors can be calculated for any pyrometer for all possible values of emissivity. The limitations of both types for direct measurement of true temperature are discussed and the errors likely to result when true temperatures are calculated from apparent temperature from previous knowledge of emissivities.
Representation of function (2004)

For automated design analyses (specifically FMEA and SCA) it is useful to have an automated design analysis tool interpret the results of the simulation of the system under analysis in terms of the purpose of the system and the design analysis task. The description of system function (in “functional labelling”) has been shown to be a useful approach to this for systems of simple functionality. This report attempts a description of a suitable representation of function to allow the approach to be used for various design analysis tasks and as the underpinning of a functional description language of sufficient expressiveness to allow systems whose functionali ty depends on complex behaviours to be described.
