Antioxidative Effects of Oat Oil and its Fractions (1990)

Abstract The antioxidative properties of oat oil and its fractions were studied using the Rancimat method and lard, tallow and soybean oil as substrates. Oat oil extracted with isopropanol increased the induction time of oxidation of lard and tallow from 2 to 8‐fold compared with the corresponding times without antioxidants, when applied at 1.0 to 5% concentrations. The same increase in stability was achieved with 0.25 to 1.5% concentrations of the separated fractions. The most effective fraction was the lecithin fraction isolated by supercritical CO 2 extraction. Almost equal results were achieved with a single‐step ultrafiltration. Effects on the stability of soybean oil were similar but weaker.
Eco-Friendly Disperse Dyeing and Functional Finishing of Nylon 6 Using Supercritical Carbon Dioxide (2015)

In this work, a supercritical carbon dioxide assembly was successfully constructed for dyeing Nylon6 fabric. Primary experiments were carried out to confirm the possibility of bringing the dyeing up to factory scale. A series of disperse azo dyes with potential antibacterial activity were applied to dye the fabric under our study in supercritical carbon dioxide (scCO2). The factors affecting the dyeing conditions (i.e., dye concentration, time, temperature and pressure) and functional properties were discussed and compared with those in aqueous dyeing. The comparison revealed that elimination of auxiliary chemicals such as salt, carrier or dispersing agent has no diverse effect on dyeing. The color strength of the dyed fabric evaluated by using K/S measurements increased by increasing dye concentration from 2% to 6% owf. (on weight of fabric). The nylon6 fabrics dyed in supercritical carbon dioxide have good fastness properties, and especially light fastness compared with conventional exhaustion dyeing. Antibacterial activity of the dyed samples under supercritical conditions was evaluated and the results showed excellent antibacterial efficiency.
Vasa Vasorum and Plaque Neovascularization on Contrast-Enhanced Carotid Ultrasound Imaging Correlates With Cardiovascular Disease and Past Cardiovascular Events (2009)

The presence and degree of adventitial vasa vasorum and plaque neovascularization were directly associated with CVD and CVE in a retrospective study of 147 patients undergoing contrast-enhanced carotid ultrasound.
Mutations of pma-1, the Gene Encoding the Plasma Membrane H+-ATPase of Neurospora crassa, Suppress Inhibition of Growth by Concanamycin A, a Specific Inhibitor of Vacuolar ATPases (1997)

Concanamycin A (CCA), a specific inhibitor of vacuolar ATPases, inhibited growth of Neurospora crassa in medium adjusted to pH 7 or above. Mutant strains were selected for growth on medium containing 1.0 microM CCA. Sixty-four (of 66) mutations mapped in the region of the pma1 locus, which encodes the plasma membrane H+-ATPase. Analysis of V-ATPase activity in isolated vacuolar membranes from the mutant strains showed wild-type activity and sensitivity to CCA. In contrast, plasma membrane H+-ATPase activity in isolated plasma membranes from the mutants was reduced as compared with wild-type, and in four strains the activity showed increased resistance to vanadate. The most interesting change in the plasma membrane H+-ATPase was in kinetic behavior. The wild-type enzyme showed sigmoid dependence on MgATP concentration with a Hill number of 2.0, while the seven mutants tested exhibited hyperbolic kinetics with a Hill number of 1.0. One interpretation of these data was that the enzyme had changed from a functional dimer to a functional monomer. Mutation of the plasma membrane H+-ATPase did not confer resistance by preventing uptake of CCA. In the presence of CCA both wild-type and mutant strains were unable to accumulate arginine, failed to concentrate chloroquine in acidic vesicles, and exhibited gross alterations in hyphal morphology, indicating that the CCA had entered the cells and inactivated the V-ATPase. Instead, we hypothesize that the mutations conferred resistance because the altered plasma membrane H+-ATPase could more efficiently rid the cell of toxic levels of Ca2+ or protons or other ions accumulated in the cytoplasm following inactivation of the V-ATPase by CCA.
Patient Similarity via Joint Embeddings of Medical Knowledge Graph and Medical Entity Descriptions (2020)

With the prevalence and growing volume of Electronic Health Records (EHRs), there has been increasing interest in mining EHRs for improving clinical decision support. The accurate identification of patients with similar conditions based on EHRs is a key step in personalized healthcare. Existing studies model EHRs by medical knowledge graph embedding to learn the latent embeddings of medical entities (e.g., patients, medications, diagnoses and procedures). However, such precisely structured data is usually limited in quantity and in scope. Therefore, to enhance the quality of the embeddings it is important to consider more widely available medical information such as medical entity descriptions. In this paper we propose a novel framework, called Deep Patient Similarity (DeepPS). Specifically, DeepPS incorporates medical entity descriptions by augmenting the embeddings of medical entities and relations with the embeddings of words, which leverages both information from medical knowledge graph structures and the contexts of medical entity descriptions. Furthermore, DeepPS employs the embeddings to patient similarity learning by leveraging Siamese Convolutional Neural Network (CNN) with Spatial Pyramid Pooling (SPP). Extensive experiments on real datasets are conducted to show superior performance of our proposed framework.
An Investigation of the Structure-Property Relationships for High Performance Thermoplastic Matrix, Carbon Fiber Composites with a Tailored Polyimide Interphase (1998)

The aqueous suspension prepregging technique was used to fabricate PEEK and PPS matrix composites with polyimide interphases of tailored properties. The structure-property relationships of Ultem-type polyimide and BisP-BTDA polyimide which were made from various water soluble polyamic acid salts were studied. The molecular weight of the polyimides was shown to be dependant upon the selection of the base used for making the polyamic acid salt. The development of an Ultem-type polyimide with controlled molecular weight and properties similar to commercial Ultem 1000 was accomplished with the Ultem-type TPA+ polyamic acid salt. Both the Ultem-type polyimides and the BisP-BTDA polyimides derived from the NH4+ salt and the TMA+ salt were shown to crosslink at elevated temperatures. Blends of Ultem-type polyimide with PEEK and BisP-BTDA polyimide with PEEK were prepared to study the structure-property relationships of model composite matrices. Since both polyimides are miscible with PEEK, interdiffusion of the polyimides with PEEK is expected, however, the interdiffusion behavior is complicated by the crosslinking mechanism of the polyimides. Ultem-type polyimide interphase, PEEK matrix composites and BisP-BTDA polyimide interphase, PEEK matrix composites were fabricated using the aqueous suspension prepregging technique and evaluated to determine the effects of the interphase properties on the bulk composite performance and durability. Three different Ultem-type polyimides from the NH4+, TMA+ and TPA+ polyamic acid salts were used and two different BisP-BTDA polyimides from the NH4+ and TMA+ polyamic acid salts were used. The transverse flexure strength was used to qualitatively rank the composites by level of interfacial shear strength. The longitudinal tensile strength of the composites was shown to vary with relative interfacial shear strength. The trend of these data qualitatively support the existence of a maximum longitudinal tensile strength at an optimum interfacial shear strength. Notched fatigue testing of the Ultem-type polyimide interphase, PEEK matrix composites showed that the initial split growth rate increased with decreasing relative interfacial shear strength. Ultem-type polyimide interphase, PPS matrix composites were fabricated using the aqueous suspension prepregging technique and evaluated to determine the effects of the interphase properties on the bulk composite performance. Three different Ultem-type polyimides from the NH4+, TMA+ and TPA+ polyamic acid salts were used. The transverse flexure strength was used to qualitatively rank the composites by level of interfacial shear strength. The longitudinal tensile strength of the composites was shown to vary with relative interfacial shear strength. The trend of these data qualitatively support the existence of a maximum longitudinal tensile strength at an optimum interfacial shear strength.
Polypeptides with High Zwitterion Density for Safe and Effective Therapeutics (2018)

The commonly used "stealth material" poly(ethylene glycol) (PEG) effectively promotes the pharmacokinetics of therapeutic cargos while reducing their immune response. However, recent studies have suggested that PEG could induce adverse reactions, including the emergence of anti-PEG antibodies and tissue histologic changes. An alternative stealth material with no or less immunogenicity and organ toxicity is thus urgently needed. We designed a polypeptide with high zwitterion density (PepCB) as a stealth material for therapeutics. Neither tissue histological changes in liver, kidney, or spleen, nor abnormal behavior, sickness or death was induced by the synthesized polymer after high-dosage administration for three months in rats. When conjugated to a therapeutic protein uricase, the uricase-PepCB bioconjugate showed significantly improved pharmacokinetics and immunological properties compared with uricase-PEG conjugates.
Fabrication techniques of lithium niobate waveguides (1988)

In the paper, the most commonly used fabrication techniques of optical waveguides in lithium niobate are reviewed. Diffusion processes such as out-diffusion of lithium oxide from the crystal surface, in-diffusion of metals, ion exchange and proton exchange, and ion implantation are analysed. The characteristics of LiNbO3 optical waveguides prepared by the different technological procedures, are reported in relation with the fabrication conditions. High quality optical waveguides on lithium niobate can be produced by Ti in-diffusion in a dry O2 atmosphere at temperatures above 1000°C for long diffusion times (>10 h). However, despite the large amount of research done in this field, correlations between optical properties and structural characteristics have not yet been established.
Physicochemical Properties of Calcium Lignosulfonate with Different Molecular Weights as Dispersant in Aqueous Suspension (2008)

Five purified calcium lignosulfonate (CL) fractions with different molecular weights were obtained by fractionation using ultrafiltration and dialysis. The influence of molecular weight on their physicochemical properties was investigated by determining the properties of five fractions. TEM and ESEM imaging indicated that CL has a globular structure to form locally regular colloidal assemblies with the diameter of approximately 200 ∼ 300 nm. Fraction3 (M w is 7621) with the molecular weight of 5,000–l0,000 has more sulfonic and carboxyl group, so the highest zeta potential (−36 mV) can be charged on the TiO2 particles. With the increase of molecular weight, the hydrophobicity and surface activity of CL in aqueous solution increase, so Fraction5 (M w is 21646) which molecular weight is more than 30000 has the biggest adsorption amount. The adsorption characteristic of CL on solid-water interface have great impact on the dispersive properties of TiO2 particle in aqueous solution and the higher adsorption capacity is helpful to improve the dispersive ability of CL. On the other hand, the surface charge of TiO2 particle absorbing CL is another important factor to the dispersive ability of CL. Furthermore, when the CL concentration in TiO2 suspension is less than 4 mg/mL, Fraction3 has the best dispersive ability because the electrostatic repulsion effect is controlling factor. The dispersive ability of CL increases with the increase of molecular weight when the CL concentration in TiO2 suspension is more than 4 mg/mL, so Fraction5 has the best dispersive ability owing to the steric hindrance effect.
Large Margin Discriminant Hashing for Fast k-Nearest Neighbor Classification (2010)

Since the k-nearest neighbor (k-NN) classification is computationally demanding in terms of time and memory, approximate nearest neighbor (ANN) algorithms that utilize dimensionality reduction and hashing are gathering interest. Dimensionality reduction saves memory usage for storing training patterns and hashing techniques significantly reduce the computation required for distance calculation. Several ANN methods have been proposed which make k-NN classification applicable to those tasks that have a large number of training patterns with very high-dimensional feature. Though conventional ANN methods try to approximate Euclidean distance calculation in the original high-dimensional feature space with much lower-dimensional subspace, the Euclidean distance in the original feature space is not necessarily optimal for classification. According to the recent studies, metric learning is effective to improve accuracy of the k-NN classification. In this paper, Large Margin Discriminative Hashing (LMDH) method, which projects input patterns into low dimensional subspace with the optimized metric for the k-NN classification, is proposed.
Controlled Synthesis of CeO<sub>2</sub>/Graphene Nanocomposites with Highly Enhanced Optical and Catalytic Properties (2012)

In this paper, CeO2 nanocubes with the (200)-terminated surface/graphene sheet composites have been prepared successfully by a simple hydrothermal method. It is found that the CeO2 nanocubes with high crystallinity and specific exposed surface are well dispersed on well-exfoliated graphene surface. The (200)-terminated surface/graphene sheet composites modified electrode showed much higher sensitivity and excellent selectivity in its catalytic performance compared to a CeO2 nanoparticle-modified electrode. The photoluminescence intensity of the CeO2 anchored on graphene is about 30 times higher than that of pristine CeO2 crystals in air. The higher oxygen vacancy concentration in CeO2 is supposed to be an important cause for the higher photoluminescence and better electrochemical catalytic performance observed in the (200)-terminated surface/graphene sheet composites. Such ingenious design of supported well-dispersed catalysts in nanostructured ceria catalysts, synthesized in one step with an exposed high-activity surface, is important for technical applications and theoretical investigations.
Experimental and clinical effects of magnesium infusion in the treatment of neonatal pulmonary hypertension. (1995)

The appropriate treatment of persistent pulmonary hypertension of the newborn has led to the search for a specific pulmonary vasodilator. Persistent pulmonary hypertension of the newborn is characterized by a high pulmonary vascular resistance resulting in right to left shunting across the fetal channels. The ratio of pulmonary vascular resistance to systemic vascular resistance determines the magnitude of this shunt, and agents which lower both pulmonary and systemic blood pressure do not alleviate the right to left intracardiac shunt. Numerous vasodilator agents,including tolazoline, prostaglandins and nitrovasodilators, have been used but all have been associated with problematic falls in systemic blood pressure. Magnesium, called nature's calcium blocker, antagonizes calcium ion entry into smooth muscle cells, thus promoting vasodilatation. Magnesium is also a non-specific vasodilator,and while potentially lowering pulmonary vascular resistance, has been shown to cause a fall in systemic blood pressure in neonatal models of hypoxic or septic pulmonary hypertension. Case reports and a series of cases have noted beneficial effects in human newborns, which may have been due to other effects of magnesium (eg, sedation, muscle relaxation, bronchodilatation and cardioprotection). There are, however, no reported prospective randomized controlled trials of magnesium sulphate in human newborns with pulmonary hypertension. More recently, the discovery that inhaled nitric oxide acts as a specific pulmonary vasodilator without systemic side effects may reduce enthusiasm for the use of magnesium infusions in neonates with pulmonary hypertension. There appears to be sufficient evidence at present to justify a prospective randomized controlled trial to evaluate the role of magnesium infusion as a specific pulmonary vasodilator for the treatment of pulmonary hypertension in hypoxic human newborns.
Ab initio and molecular mechanics (MM3) calculations on propargyl alcohol and derivatives (1996)

Ab initio calculations at both the Hartree-Fock and Møller-Plesset (MP2) levels of theory utilizing various basis sets were carried out on propargyl alcohol and its derivatives. The results of these calculations were used in conjunction with available experimental data in the formulation of an MM3 force field for these compounds. The energetic data obtained via the ab initio calculations were modeled well within the MM3 formalism, and are in agreement with the experimental results to within 1 kcal mol−1. For those structural parameters which were the focus of this study, the calculated results agreed well with existing experimental and ab initio data. The vibrational frequencies are also in good agreement with only small deviations in a few modes of methyl propargyl ether and propargyl fluoride.
Proteomic and transcriptomic analysis of the response to bile stress of Lactobacillus casei BL23 (2012)

Lactobacillus casei is a lactic acid bacterium commonly found in the gastrointestinal tract of animals, and some strains are used as probiotics. The ability of probiotic strains to survive the passage through the gastrointestinal tract is considered a key factor for their probiotic action. Therefore, tolerance to bile salts is a desirable feature for probiotic strains. In this study we have characterized the response of L. casei BL23 to bile by a transcriptomic and proteomic approach. The analysis revealed that exposure to bile induced changes in the abundance of 52 proteins and the transcript levels of 67 genes. The observed changes affected genes and proteins involved in the stress response, fatty acid and cell wall biosynthesis, metabolism of carbohydrates, transport of peptides, coenzyme levels, membrane H(+)-ATPase, and a number of uncharacterized genes and proteins. These data provide new insights into the mechanisms that enable L. casei BL23 to cope with bile stress.
Photo-Acoustic Measurement of Thermal Conductivity of Thin Films and Bulk Materials (2000)

The photoacoustic (PA) technique is one of many techniques for measuring thermal conductivity of thin films. Compared with other techniques for thermal conductivity measurement, the photoacoustic method is relatively simple, yet is able to provide accurate thermal conductivity data for many types of thin films and bulk materials. In this work, the PA measurement in a high frequency range is made possible by a newly developed PA apparatus, which extends the limit of the PA technique. Thermal conductivities of SiO2 with thicknesses from 0.05 to 0.5 μm on Si wafer, e-beam evaporated thin nickel film on Si wafer, and thermal barrier coatings are obtained. In addition to the commonly used phase shift fitting, which is only appropriate for thermally-thin films, an amplitude fitting method is developed and employed for measuring both thin films and bulk materials with smooth or rough surfaces. Comparing results by amplitude fitting to those obtained by other methods and reference values shows good agreements. Applications and limitations of the photoacoustic technique are discussed.
iCFP: Tolerating All-Level Cache Misses in In-Order Processors (2010)

In-order continual flow pipeline (iCFP) is an in-order pipeline that allows execution to flow around data cache misses. When a cache miss occurs, iCFP executes and speculatively retires miss-independent instructions. It saves miss-dependent instructions in a slice buffer. When the miss returns, iCFP reexecutes the contents of the slice buffer and merges the results into working state. iCFP exploits existing support for multithreading and several novel components.
Modified Pouchitis Disease Activity Index (2003)

Diagnosis based on the modified pouchitis disease activity index offers similar sensitivity and specificity when compared with the pouchitis disease activity index for patients with acute or acute relapsing pouchitis. Omission of endoscopic biopsy and histology from the standard pouchitis disease activity index would simplify pouchitis diagnostic criteria, reduce the cost of diagnosis, and avoid delay associated with determining histology score, while providing equivalent sensitivity and specificity.
Differential migration of T and B cells during an acute inflammatory response (1991)

Inflammation in the liver and mammary glands of sheep caused by challenge infection with Taenia hydatigena or infusion of killed Staphylococcus aureus, respectively were characterized by the recruitment of both T and B cells. The patterns of migration of these two major lymphocyte subpopulations were distinctly different. While T cells seemed to migrate out of existing, flat endothelium-lined blood vessels resulting in a diffuse distribution at the sites of inflammation, B cells were characteristically present as clusters of tightly packed cells at restricted sites in the inflamed tissue. Within these B cell clusters distinct capillary vessels lined with plumb endothelial cells were always present suggesting that they were the sites of intense migration of B cells originating from the draining lymph nodes. These results indicate differential regulation of adhesion molecules on B and T cells and/or their ligands on endothelium during acute inflammatory reactions.
