Dermatomal somatosensory evoked potentials in the diagnosis of lumbosacral spinal stenosis: Comparison with imaging studies (1992)

Dermatomal somatosensory evoked potentials (DSEPs) and computerized tomography/magnetic resonance (CT and/or MR) images were retrospectively analyzed to evaluate their relationship in the diagnosis of lumbosacral spinal stenosis (SS). Of 155 patients referred for DSEPs with a clinical suspicion of lumbosacral SS, 58 met the inclusion criteria. DSEP abnormality was defined as: (1) N1 latency absent or greater than 2.5 SD; (2) side-to-side latency difference greater than 2 SD; (3) amplitudes greater than 2 SD below the mean; or (4) amplitude ratio greater than 2 SD. Involvement of two or more DSEP levels by any of the above criteria was labeled multiple root disease (MRD). Involvement of one level was labeled single root disease (SRD). Images were reviewed independently by a neuroradiologist. Results revealed 54 subjects with SS by imaging; 42 had MRD and 8 had SRD by DSEPs. Sensitivity for MRD and SS was 78%, and for MRD plus SRD and SS was 93%.
The Volumetric Efficiency of Direct and Port Injection Gasoline Engines with Different Fuels (2002)

<div class="htmlview paragraph">A study has been undertaken with a single-cylinder engine, based on the Mitsubishi GDi combustion system, that has the option of either port injection or direct injection. Tests have been undertaken with pure fuel components (methane, iso-octane, toluene and methanol), and a representative gasoline that has also been tested with the addition of 10% methanol and 10% ethanol. The volumetric efficiency depends both on the fuel and its time and place of injection. For stoichiometric operation with unleaded gasoline, changing from port injection to direct injection led to a 9% increase in volumetric efficiency, which was improved by a further 3% when 10% methanol was blended with the gasoline.</div> <div class="htmlview paragraph">The improvements in volumetric efficiency will be used to quantify the extent of charge cooling by fuel evaporation, and these will be compared with predictions assuming the maximum possible level of fuel evaporation.</div>
Static control-flow analysis for reverse engineering of UML sequence diagrams (2005)

UML sequence diagrams are commonly used to represent the interactions among collaborating objects. Reverse-engineered sequence diagrams are constructed from existing code, and have a variety of uses in software development, maintenance, and testing. In static analysis for such reverse engineering, an open question is how to represent the intraprocedural flow of control from the code using the control-flow primitives of UML 2.0. We propose simple UML extensions that are necessary to capture general flow of control. The paper describes an algorithm for mapping a reducible exception-free intraprocedural control-flow graph to UML, using the proposed extensions. We also investigate the inherent tradeoffs of different problem solutions, and discuss their implications for reverse-engineering tools. This work is a substantial step towards providing high-quality tool support for effective and efficient reverse engineering of UML sequence diagrams.
Field Tests of a Slim Carbon/Oxygen Tool for Reservoir Saturation Monitoring (1993)

ABSTRACT Oil production from many major producing reservoirs is now maintained by water injection programs. The resulting mixed and often very low-salinity formation water presents a serious problem when monitoring water saturation with traditional pulsed neutron capture (PNC) tools. A slim carbon/oxygen (CAD) pulsed neutron tool tested recently in many regions around the world addresses the problems encountered in low- and mixed-salinity environments. The tool's dual y-ray detectors and flexible neutron burst timing allow it to be used for carbon/oxygen logging and, in a separate pass, for PNC logging. New detector and accelerator technologies as well as advanced data processing allow logging speeds that meet or exceed those of traditional, large, single-detector C/O tools.
Preliminary results from a phase I/II study of perillyl alcohol intranasal administration in adults with recurrent malignant gliomas (2007)

14037 Background: Deregulated p21-Ras function, as a result of mutation, overexpresion or growth factor-induced overactivation, contributes to growth of malignant gliomas. Perillyl alcohol (POH) is a monoterpene with preclinical antitumor activity in several types of tumor in rodent models and is currently under phase I and phase II clinical trials. Its proposed mechanism of action involves inhibition of post- translational isoprenylation of small G proteins, including p21-Ras, thereby blocking signal transduction Methods: The intranasal delivery is a practical and non-invasive approach that allows therapeutic agents, which do not cross the blood brain barrier (BBB) to enter the Central Nervous System (CNS), reducing unwanted systemic side effects. Applying this method we performed a phase I / II study with POH intranasal administration in patients with relapsed malignant gliomas after standard treatment: surgery, radiotherapy and chemotherapy. POH was administrated in concentration 0.3% volume/volume (55mg) 4 times daily. Results: Thirty-seven patients enrolled being 29 with glioblastoma multiform (GBM), 5 with grade III astrocytoma (AA) and 3 with anaplastic oligodendroglioma (AO). The results showed that POH is well tolerated and display at 6 months of treatment partial responses in 1 patient (3,4%) with GBM and 1 patient (33,3%) with AO; stable disease in 13 patients (44,8%) with GBM, 3 patients (60%) with AA and 1 patient (33,3%) with AO; progressive response in 15 patient (51,7%) with GBM, 2 patients (40%) with AA e 1 patient (33,3%) with AO. Conclusions: The POH intranasal delivery in a concentration of 0.3% volume/volume (55 mg) is well tolerated, and may prolong survival in patients with relapsed malignant gliomas patients. No significant financial relationships to disclose.
Calculation of Minimum-Detectable-Concentration Levels of Radioxenon Isotopes Using the PNNL ARSA System (2006)

Measurement of xenon fission product isotopes is a key element in the global network being established to monitor the Comprehensive Nuclear-Test-Ban Treaty. The automated Radio-xenon Analyzer/Sampler (ARSA), built by Pacific Northwest National Laboratory, can detect 131mXe, 133mXe, 133Xe, and 135Xe via a beta-gamma counting system. Due to the variable background and sources of these four radio-xenon isotopes, it is important to have as sensitive a detection system as possible and to quantify the Minimum-Detectable-Concentrations (MDC) that such a system will be able to detect to preclude false negative and false positive results. From data obtained from IAR in Germany MDC values for 133Xe were well below the 1 mBq/SCMA as required by the PTS for the Comprehensive Test BAn Treaty [WGB TL-11,1999].

Ten electrophoretic methods compared with a selected method for quantifying lactate dehydrogenase isoenzymes in serum. (1988)

Using the Selected Method of McKenzie and Henderson (Selected Methods Clin Chem 1983;10:59-67) as a reference method, we compared the performance of 10 commercially available methods for determination of lactate dehydrogenase (LD, EC 1.1.1.27) isoenzymes. Results were expressed as percentage of total LD activity, as determined with two different types of densitometers shown to have an average difference less than 1.4% for each isoenzyme. All methods gave generally comparable results, as judged by Bland-Altman plots and correlation analyses. However, in general, estimates by the commercial methods for LD-1, LD-2, and LD-3 were lower, and for LD-4 and LD-5 were higher than with the Selected Method. The overall CV was less than 20% for all methods and isoenzymes, except for LD-4 and LD-5 by the Beckman Paragon, Helena LD-VIS, Gel LDH, Gel PC, and Iso Dot, Gelman LDH Isozyme, and Sebia Hydragel assays, for which it was greater than 20%. Overall, accuracy was best with the Helena Iso Dot and LD-VIS assays, followed by the Corning LD Flur assay; accuracy was poorest with the Gelman LDH Isozyme, Sebia Hydragel, and Beckman Paragon assays.
Mechanism-Based Pharmacokinetic Model for Paclitaxel (2001)

Earlier PK models for paclitaxel have been empirical. This study shows that a mechanistic model can be used to describe the nonlinear PK of paclitaxel. There is an indication that the PK/PD relationship is not the same for unbound and total plasma concentrations.
Energetics of peptide (pHLIP) binding to and folding across a lipid bilayer membrane (2008)

The pH low-insertion peptide (pHLIP) serves as a model system for peptide insertion and folding across a lipid bilayer. It has three general states: (I) soluble in water or (II) bound to the surface of a lipid bilayer as an unstructured monomer, and (III) inserted across the bilayer as a monomeric alpha-helix. We used fluorescence spectroscopy and isothermal titration calorimetry to study the interactions of pHLIP with a palmitoyloleoylphosphatidylcholine (POPC) lipid bilayer and to calculate the transition energies between states. We found that the Gibbs free energy of binding to a POPC surface at low pHLIP concentration (state I-state II transition) at 37 degrees C is approximately -7 kcal/mol near neutral pH and that the free energy of insertion and folding across a lipid bilayer at low pH (state II-state III transition) is nearly -2 kcal/mol. We discuss a number of related thermodynamic parameters from our measurements. Besides its fundamental interest as a model system for the study of membrane protein folding, pHLIP has utility as an agent to target diseased tissues and translocate molecules through the membrane into the cytoplasm of cells in environments with elevated levels of extracellular acidity, as in cancer and inflammation. The results give the amount of energy that might be used to move cargo molecules across a membrane.

Some Objective Tests of the Legibility of Relief Maps (1975)

AbstractAbstractThe legibility of four different types of relief map (contours, contours with hill shading, layer tints and digital or spot height maps) was compared using 13 different map reading test questions administered to 179 subjects. Many of the questions showed large and statistically significant differences between the four types of map, but no single type of map was best for all purposes. The results demonstrate that the choice of an appropriate relief map has a very real effect on the map reader's performance, and that this choice must depend on the way the map is to be used.
Interaction between support and V2O5 in the selective catalytic reduction of NO by NH3 (2014)

V2O5-based catalysts for NH3-selective catalytic reduction (SCR) have been prepared by an impregnation method using different supports including nano-TiO2, meso-TiO2, nano-ZrO2, meso-Al2O3 and meso-SiO2. Activity evaluations clarified that V2O5/meso-TiO2 possessed the highest activity and a wide activity–temperature window of 240–400 °C, while V2O5/nano-TiO2 and V2O5/nano-ZrO2 had activities were the next most active to V2O5/meso-TiO2. The realized NO removal was lowest over V2O5/meso-Al2O3 and V2O5/meso-SiO2. In flue gas with 900 ppm SO2 and 10 vol.% steam the catalyst V2O5/meso-TiO2 showed the best activity stability at 350 °C and 240 °C. Characterizing the catalysts revealed that the differences in their redox properties and acidities should be responsible for their different activities and poisoning resistance. The dispersion of V2O5 on all the supports obviously decreased its H2-reduction temperature, and the lower the reduction temperature, the better the catalyst appeared to be in activity and poisoning resistance. Overall, only the TiO2 support and its consequent interactions with V2O5 guaranteed the expected good activity and also poisoning resistance for NH3-SCR of NO. The higher pore volume of meso-TiO2 enabled a larger tolerance capacity to ammonium sulfate and sulfite so that this catalyst had better low-temperature activity stability.
Measurement of Lysozyme−Lysozyme Interactions with Quantitative Affinity Chromatography (2004)

A chromatographic method is used to measure lysozyme−lysozyme interactions in aqueous salt solutions as a function of solution conditions (pH, ionic strength, and salt type). Compared to static light scattering and membrane osmometry, the chromatographic method requires significantly less protein. To interpret retention-time data, it is necessary to account for multibody interactions between a mobile lysozyme molecule and immobilized lysozyme molecules on the support surface. The interaction between lysozyme molecules may be described by a potential of mean force that contains hard-sphere, electrostatic, and square-well contributions. Square-well depths from chromatographic data are in semiquantitative agreement with those from osmotic second virial coefficients from static light scattering measurements.

Fast realistic multi-action recognition using mined dense spatio-temporal features (2009)

Within the field of action recognition, features and descriptors are often engineered to be sparse and invariant to transformation. While sparsity makes the problem tractable, it is not necessarily optimal in terms of class separability and classification. This paper proposes a novel approach that uses very dense corner features that are spatially and temporally grouped in a hierarchical process to produce an overcomplete compound feature set. Frequently reoccurring patterns of features are then found through data mining, designed for use with large data sets. The novel use of the hierarchical classifier allows real time operation while the approach is demonstrated to handle camera motion, scale, human appearance variations, occlusions and background clutter. The performance of classification, outperforms other state-of-the-art action recognition algorithms on the three datasets; KTH, multi-KTH, and Hollywood. Multiple action localisation is performed, though no groundtruth localisation data is required, using only weak supervision of class labels for each training sequence. The Hollywood dataset contain complex realistic actions from movies, the approach outperforms the published accuracy on this dataset and also achieves real time performance.
Lotus effect surface for prevention of microelectromechanical system (MEMS) stiction (2005)

Due to the surface smoothness of micromachined structures, strong adhesion forces between these fabricated structures and the substrate can be developed. Once contact is made, the magnitude of these forces is sufficient to deform and attract these structures to the substrate, resulting in device failure. This type of failure is one of the dominant sources of yield loss in microelectromechanical system (MEMS) fabrications. The basic approaches to prevent stiction include increasing surface roughness and/or lowering solid surface energy by coating with low surface energy materials. By nature, the Lotus Effect surface is an excellent model surface of a combined effect of hydrophobicity and micro/nano scale structure topography. Such surfaces have water droplet contact angles of 150/spl deg/ or higher. The intrinsically superhydrophobic surfaces can avoid an attractive capillary force which pulls the MEMS microstructure to the substrate; as such they reduce van der Waals forces as well. To prepare a lotus effect surface, aligned carbon nanotubes (ACNTs) that are perpendicular to the substrate surface are created. The nanotubes were grown in a chemical vapor deposition (CVD) tube furnace system from a vapor-phase mixture of xylene and ferrocene. The ferrocene was the nucleation initiator and xylene as the carbon source. Multiwalled carbon nanotubes of 20-30 nm in diameter were fabricated onto SiO/sub 2/ surfaces that were deposited by the plasma enhanced chemical vapor deposition (PECVD) method. The average center-to-center spacing (pitch) between adjacent nanotubes was /spl sim/50 nm. The as-grown vertical nanotubes showed good adhesion to the substrate, which made the nano-scaled roughness possible. The initial water contact angle on the as-grown aligned CNT surface was 155/spl deg/. To improve the stability of the superhydrophobic surface, the aligned CNTs were modified by fluorinated polymers formed by PECVD. The as-grown CNTs were characterized using scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM).
Identification of circulating long non-coding RNA GAS5 as a potential biomarker for non-small cell lung cancer diagnosis (2017)

Non-small cell lung cancer (NSCLC) is one of the most malignant cancers in the world. Early diagnosis of NSCLC has become especially important for patient treatment and prognosis. Increasing evidence suggest that long non-coding RNA GAS5 plays vital roles in cancer proliferation and differentiation in NSCLC. However, its clinical value in the diagnosis of NSCLC is unclear. The objective of this study was to evaluate the importance of circulating GAS5 as a biomarker for NSCLC diagnosis. In our study, quantitative real-time PCR (QRT-PCR) was applied to detect the GAS5 expression level in 80 pairs of cancer tissues and 57 pairs of plasma samples of NSCLC patients. Further analysis was performed to study the differential expression of circulating GAS5 in 111 NSCLC patients and 78 healthy controls in our study. The results showed that GAS5 decreased in NSCLC tissues compared to noncancerous tissues (P<0.001). Furthermore, the GAS5 expression level was statistically declined in early stage of NSCLC before surgery compared with healthy controls (P<0.05) and sharply increased in postoperative groups (P=0.026). ROC curve analysis for early stage of NSCLC with the combination of GAS5, CEA and CA199 showed that the area under the ROC curve (AUC) was 0.734 (95% CI, 0.628‑0.839; P<0.0005). In conclusion, circulating GAS5 could be functioned as a potential combined biomarker for screening NSCLC and patient monitoring after surgical treatment.
Dental Diseases in Japanese Skeletal Remains (1982)

For the purpose of studying the reduction of human dentition, an examination of dental diseases in the Muromachi era was undertaken. Materials used were 24 maxillae and 17 mandibles with permanent or mixed dentitions, selected from 127 Japanese skulls from the Muromachi era. As the number of materials available was not sufficient to represent the character of the population of this period, the purpose of this paper might be limited just to present the data obtained.By comparing these data to those from the later Jomon, Kofun, Kamakura, and modern ages, however, it might still be possible to consider that the specificity of dental diseases in this period was similar to that in the Kamakura era. The discrepancy seemed to be the main pathogenetic factor also in the Muromachi era.
