Physical Activity Status and Adverse Age-Related Differences in Coagulation and Fibrinolytic Factors in Women (1998)

Adverse changes in coagulation and fibrinolytic factors are thought to contribute to the increased risk of cardiovascular disease and atherothrombosis with age. We tested the hypothesis that such age-related changes in specific coagulation and fibrinolytic factors are absent in physically active women. Resting levels of plasma fibrinogen, tissue-type plasminogen activator (t-PA) antigen and activity, plasminogen activator inhibitor-1 (PAI-1) antigen and activity, and fibrin D-dimer were measured in 24 healthy premenopausal women: 11 sedentary (aged 28+/-1 years; Pre-S) and 13 physically active (aged 30+/-1 years; Pre-PA) and in 27 healthy postmenopausal women: 14 sedentary (aged 61+/-1 years; Post-S) and 13 physically active (aged 58+/-1 years; Post-PA). Post-S had higher (P<.05) fibrinogen, t-PA antigen, PAI-1 antigen, PAI-1 activity, and fibrin D-dimer levels and lower t-PA activity than Pre-S. Post-PA demonstrated lower (P<.01) plasma fibrinogen, t-PA antigen, PAI-1 antigen, and PAI-1 activity and higher (P<.01) t-PA activity levels than Post-S. In addition, plasma fibrin D-dimer levels tended (P=.06) to be lower in Post-PA than in Post-S. Although plasma levels of fibrinogen and fibrin D-dimer in Post-PA were lower than in Post-S, they were higher (P<.05) than in Pre-PA. Importantly, however, the fibrinolytic profile of Post-PA did not differ from that of Pre-PA. The results of the present study demonstrate that the adverse age-associated differences in plasma fibrinogen concentrations and the endogenous fibrinolytic system in sedentary healthy women are either attenuated or absent in highly physically active women. The smaller or absent age-related differences in coagulation and fibrinolytic factors in women who habitually exercise may represent an important mechanism contributing to their lower age-related increase in both cardiovascular disease and atherothrombotic events. Future studies need to determine whether women who are moderately active would demonstrate the same favorable hemostatic profile.
Bayesian CFO Estimation in OFDM Systems (2009)

This paper addresses the problem of carrier frequency offset (CFO) estimation in orthogonal frequency division multiplexing (OFDM) systems using Bayesian method. Depending on the availability of the noise variance, two general CFO estimators are derived. Furthermore, the two general maximum a posteriori (MAP) estimators are developed into several special cases based on different degrees of prior information on parameters. The relationships between the proposed estimators and existing estimators are comprehensively investigated. Finally, numerical results demonstrate the effects of employing different prior information on the estimation performances.
Interactions between 60-GHz millimeter waves and artificial biological membranes: dependence on radiation parameters (2006)

Due to the increasing interest in millimeter-wave (MMW) applications for wireless communication systems, the investigation of their potential biological effects is of utmost importance. In this paper, we report experimental results of the study of interactions between low-power radiation at 60 GHz and artificial models of biological membranes. In the first part of this study, we demonstrate an increase of superficial pressure of phospholipid monolayers during MMW exposure. Two of the most prominent in quantity lipid constituents of biological membranes, dipalmitoylphosphatidylcholine and dioleoylphosphatidylcholine, are considered. The role of different radiation parameters, namely, power density, polarization, amplitude modulation, permanent, and discontinuous exposure, is discussed. The results have proved to be reproducible in independent experiments. In the second part of this study, through atomic force microscopy analysis, we investigate the influence of MMW radiation on the microdomain distribution in mixed phospholipid monolayers with phase separation. No significant modifications are observed in microdomain distribution after 5 h of exposure. The main outcomes of this study lead to the conclusion that short-term low-power MMW exposures result in an increase of lateral pressure of the phospholipid monolayer, but their influence is not sufficiently strong to disturb phospholipid microdomain organization in biomembranes

Anti-Inflammatory Effects and Mechanisms ofFatsia polycarpaHayata and Its Constituents (2013)

Fatsia polycarpa, a plant endemic to Taiwan, is an herbal medicine known for treating several inflammation-related diseases, but its biological function needs scientific support. Thus, the anti-inflammatory effects and mechanisms of the methanolic crude extract (MCE) of F. polycarpa and its feature constituents, that is, brassicasterol (a phytosterol), triterpenoids 3 α -hydroxyolean-11,13(18)-dien-28-oic acid (HODA), 3 α -hydroxyolean-11-en-28,13 β -olide (HOEO), fatsicarpain D, and fatsicarpain F, were investigated. MCE and HOEO, but not brassicasterol, dose-dependently inhibited lipopolysaccharide- (LPS-)induced expression of inducible nitric oxide synthase and cyclooxygenase-2 in RAW 264.7 macrophage line, whereas HODA, fatsicarpain D and fatsicarpain F were toxic to RAW cells. Additionally, MCE and HOEO suppressed LPS-induced production of nitric oxide, prostaglandin E2, and interleukin-1 β and interfered with LPS-promoted activation of the inhibitor kappa B kinase (IKK)/nuclear factor- κ B (NF- κ B) pathway, and that of the mitogen-activated protein kinases (MAPKs) extracellular signal regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In animal tests, MCE and HOEO effectively ameliorated 12-O-tetradecanoylphorobol-13 acetate- (TPA-)induced ear edema of mice. Thus, MCE of F. polycarpa exhibited an obvious anti-inflammatory activity in vivo and in vitro that likely involved the inhibition of the IKK/NF- κ B pathway and the MAPKs, which may be attributed by triterpenoids such as HOEO.

16 Pixel HEB Heterodyne Mixer Array for 2.5 THz (2007)

A 16 pixel heterodyne receiver for 2.5 THz has been developed based on NbN superconducting hot-electron bolometer (HEB) mixers. The receiver uses a quasioptical RF coupling approach where HEB mixers are integrated into double dipole antennas on 1.5 mum thick Si3N4/ SiO2 membranes. Spherical mirrors (one per pixel) and backshort distance from the antenna have been used to design the output mixer beam profile. We present here the results of the antenna simulations using HFSS and ADS, as well as the beam calculations after the collimating mirror.
Testing CO2-Foam for Mobility Control at Rock Creek (1985)

ABSTRACT This paper reports the objectives, design and progress of a field test of "CO2-foam" as a lowered mobility displacing fluid. It includes the background of mobility control considerations leading to the trial, and describes the influence on it of various operational conditions and constraints. The Rock Creek oil field of Roane County, West Virginia, has been produced since 1906 from a low permeability sandstone with high clay content, and is now near the end of economic life. The area utilized in this test is a smaller portion of two ten-acre five-spots that have been subjected to a conventional CO2 flood and subsequent waterflooding, in addition to gas recycling and primary production. A major goal of the test was to determine whether the oil remaining in this area could be displaced by a slug of thickened CO2 to form a mobile oil bank that could be detected at a nearby observation well. A second goal was to test the injectivity of CO2-foam as liquid CO2 and dilute surfactant solution were pumped simultaneously down fiberglass tubing into the injection well. The design of the test was based on published measurements of the ability of the chosen surfactant (Alipal CD128) to form a foam-like dispersion with liquid CO2, on stability at reservoir temperature (73°F; 23°C), on the extent of adsorption onto the reservoir rock, and on the appropriate values of the relative mobility of the CO2-foam (0.2 cp-1). Although it has been possible to inject the target quantity of CO2 foam, the injection of chase water has not yet been completed.
Web-based stepped collaborative care intervention in the context of advanced cancer. (2014)

9522 Background: According to the NIH consensus statement, the three most common and debilitating symptoms for cancer patients are depression, pain and fatigue. The aims of this study were to test the efficacy of a web-based collaborative care intervention to reduce cancer-related symptoms and improve quality of life in advanced cancer patients. Methods: Patients with advanced cancer were randomized to a web-based stepped collaborative care intervention or usual care arm. The primary outcomes of the intervention included the Center for Epidemiological Studies-Depression (CES-D), Brief Pain Inventory, the Functional Assessment of Cancer Therapy (FACT)-Fatigue, and the FACT-Hepatobiliary. Secondary outcomes included Interleukin (IL)-1b, IL-6 and Natural Killer cells and the Caregiver Quality of Life Index and Caregiver CES-D. An intent to treat analyses was performed and effect sizes were reported using the Cohen’s d (Small<0.20; Medium=0.30-0.70; Large>0.80) or Phi (Small=0.10; Medium=0.30; Large=0.50). Results: A total of 261 patients and 179 caregivers were enrolled in the study. Patients with clinical levels of symptoms, who were randomized to the intervention arm, reported reductions in depression (Cohen’s d=0.32), pain (Cohen’s d=0.74), fatigue (Cohen’s d=0.48) and improvements in quality of life (Cohen’s d =0.38) when compared to patients randomized to the usual care arm at 6-months. Patients randomized to the intervention arm also had reductions in IL-6 (Phi=0.34), IL-1b (Phi=0.38) and increases in NK cell numbers (Phi=0.49). The family caregivers of patients randomized to the intervention arm also had lower levels of stress (Cohen’s d=0.75) and depressive symptoms (Cohen’s d=0.37) when compared to the usual care arm at 6-months. Conclusions: The web-based collaborative care intervention was found to be effective in reducing cancer-related symptoms, immune system dysregulation, and improving quality of life in both the patients and family caregivers. Clinical trial information: NCT01640522.

A vibrational spectroscopic, structural and quantum chemical study of the triiodide ion (2000)

The vibrational spectra of [R3S]I3(l) (R = Me or Et) showed extra spectral features in the 145 and 170 cm−1 region, in contrast to what is predicted by the selection rules for I3− of D∞h symmetry. Depolarisation experiments showed that the 170 cm−1 peak originates from a symmetric vibration mode. The addition of an excess of I− obliterates the 170 cm−1 peak, whereas the peak at 145 cm−1 is invariant. The excess of I− also introduces a decrease in intensity of the structural effects from I3− in the LXS reduced radial distribution function. The centrosymmetric polyhalide ions Br3− and IBr2− do not exhibit analogous spectral features to the triiodide ion. The results suggest that the extra spectral features observed for the triiodide systems are caused by the presence of higher polyiodides, viz. pentaiodides formed by the disproportionation reaction 2I3− → I3(I2)− + I−, and a cation-induced, symmetry lowering of I3−. The results from the theoretical study support this showing that I3− and I5− have vibrational features in the 145 and 170 cm−1 region. The energy barrier to linear deformation is also shown to be very small both for linear and asymmetric triiodide ions, thus supporting the ideas about a Grotthus type of mechanism of conduction in polyiodides, where the triiodide ions act as iodide donors.
News video story sentiment classification and ranking (2011)

In this paper, we present a novel approach for news video story sentiment analysis. Two research challenges are addressed: news video story sentiment classification and ranking. For classification, a graph based semi-supervised learning approach is utilized to classify the news stories into sentiment classes. Graph based semi-supervised learning is able to tackle the problem of lacking labeled data. After classification, two sentiment classes are obtained: positive and negative. In order to project the news videos into sentiment space, a multimodal approach by fusing the text sentiment and visual representation scores is adopted to rank the videos in each class. For sentiment representation, inter and intra sentiment class analysis is conducted based on affinity propagation clustering and PageRank algorithm. A user study is conducted to evaluate the video ranking performance. The experimental results on the selected topics are promising and demonstrate the proposed approach is effective.
Combinatorial FSK modulation for power-efficient high-rate communications (1991)

Deep-space and satellite communications systems must be capable of conveying high-rate data accurately with low transmitter power, often through dispersive channels. A class of noncoherent Combinatorial Frequency Shift Keying (CFSK) modulation schemes is investigated which address these needs. The bit error rate performance of this class of modulation formats is analyzed and compared to the more traditional modulation types. Candidate modulator, demodulator, and digital signal processing (DSP) hardware structures are examined in detail. System-level issues are also discussed.
Corpus callosum diffusion anisotropy correlates with neuropsychological outcomes in twins disconcordant for traumatic brain injury. (2006)

Conventional and diffusion tensor MR imaging studies in twins sustaining severe pediatric traumatic brain injury identified reduction in fractional anisotropy (FA) in all regions of the corpus callosum, particularly the posterior body, rostral body, and genu, relative to healthy cotwins. FA from the rostrum, genu, anterior body, posterior body, and isthmus were correlated with measures of reading speed and comprehension; verbal working memory and math fact retrieval scores were correlated only with the rostral body FA.
High gain coherent amplification in thermally stabilized InP:Fe crystals under dc fields (1990)

After recalling the principal results of the theory of two-wave mixing gain enhancement in photorefractive InP:Fe crystals under a dc field, we report on experiments performed with several samples manufactured at CNET. For the first time, we believe, a maximum gain of 11.4 cm(-1) has been obtained under an applied dc field of 10 kV/cm in a thermally stablized crystal (T = 290 K) at lambda = 1.06 microm. In spite of a decrease in the factor n(3)r(eff)/lambda high gains (Gamma >/= 5 cm(-1)) have been achieved at lambda = 1.32microm in thick crystals. These experimental results are in good agreement with theoretical predictions.
Neutrophilic proteolysis in the cystic fibrosis lung correlates with a pathogenic microbiome (2019)

In cases of severe CF lung disease, proteolysis by host enzymes creates an amino acid-rich environment that P. aeruginosa comes to dominate, which may contribute to the pathogen's persistence by providing its preferred carbon source.

Esophageal Foreign Bodies (2022)

Children less than 5 years old are at high risk for foreign body ingestion or aspiration. Therefore, identifying workup and management principles of foreign body ingestion, in the pediatric population, is necessary for pediatric practitioners. Differentiation of caustic ingestion versus benign ingestion is necessary to determine urgency of management. Plain film X ray imaging can be used to differentiate a button battery versus a coin ingestion, based on the halo sign. The urgency of battery ingestion requires immediate medical attention and endoscopic removal, however treatment with honey during transport may improve outcomes. Perforation can occur via caustic ingestion, sometimes with a delayed presentation. However, the most common cause of esophageal perforation is iatrogenic. In many cases perforation can be managed non operatively if contained and adequately drained.
Simulation Analysis of Conduction Block in Unmyelinated Axons Induced by High-Frequency Biphasic Electrical Currents (2005)

Nerve conduction block induced by high-frequency biphasic electrical currents is analyzed using a lumped circuit model of the unmyelinated axon based on Hodgkin-Huxley equations. Axons of different diameters (5-20 microm) can not be blocked completely when the stimulation frequency is between 2 kHz and 4 kHz. However, when the stimulation frequency is above 4 kHz, all axons can be blocked. At high-frequency a higher stimulation intensity is needed to block nerve conduction. The larger diameter axon has a lower threshold intensity for conduction block. The stimulation waveform in which the pulsewidth changes with frequency is more effective in blocking nerve conduction than the waveform in which the pulsewidth is fixed. The activation of potassium channels, rather than inactivation of sodium channels, is the possible mechanism underlying the nerve conduction block of the unmyelinated axon. This simulation study further increases our understanding of axonal conduction block induced by high-frequency biphasic currents, and can guide future animal experiments as well as optimize stimulation waveforms that might be used for electrical nerve block in clinical applications.
Measurement of Concentrations of Tramp Elements in Shredder Scrap and Automobile Shredder Residue (ASR) and Their Mass Balance Analyses (2007)

Contamination of undesirable tramp metals in steel scraps from end-of-life vehicles has been of interest for many years. In this work, typical 5 mini-vehicles and 5 small-size passenger cars were dismantled and put into shredder process, in which most of the parts end-of-life vehicles were removed thoroughly before shredding process. The weights of removed parts, shredder scrap, separated non-ferrous metals and automobile shredder residue (ASR) were measured to figure out the mass balances of the end-of-life vehicles. Then, the concentration of Cu, Cr, Sn in shredder scraps and ASRs were measured. It was found that the concentrations of Cu, Cr, Sn in shredder scrap were 0.078%, 0.004%, 0% for mini-vehicles, and 0.08%, 0.015%, 0.001% for small-size passenger cars. On the other hand, relatively high concentrations of Cu, Cr, Sn in ASR were observed, which was 0.42-0.85%, 0.03-0.04%, 0.05-0.06% for mini-vehicles, and 0.59-0.74%, 0.02%, 0.04-0.15% for small-size passenger cars, respectively. It was found that most of Cu contained in the end-of-life vehicles were removed before shredding process.
Mimos: A Description Framework for Exchanging Medical Image Processing Results (2001)

Image processing plays increasingly important role in using medical images, both for routine as for research purposes, due to the growing interest in functional studies (PET, MR, etc.). Unfortunately, there exist nearly as many formats for data and results coding as image processing procedures. If Dicom presently supports a kind of structured reporting of image studies, it does not take into account the semantics of the image handling domain. This can impede the exchange and the interpretation of processing results. In order to facilitate the use of image processing results, we have designed a framework for representing image processing results. This framework, whose principle is called an "ontology" in the literature, extends the formalism, which we have used in our previous work on image databases. It permits a systematic representation of the entities and information involved in the processing, that is not only input data, command parameters, output data, but also software and hardware descriptions, and relationships between these different parameters. Consequently, this framework allows the building of standardized documents, which can be exchanged amongst various users. As the framework is based on a formal grammar, documents can be encoded using XML. They are thus compatible with Internet / Intranet technology. In this paper, the main characteristics of the framework are presented and illustrated. We also discuss implementation issues in order to be able to integrate documents, and correlated images, handling these with a classical Web browser.
