Acute Coronary Syndrome Patients With Depression Have Low Blood Cell Membrane Omega-3 Fatty Acid Levels (2008)

We found an inverse relationship between the n-3 index and the prevalence of depressive symptoms in patients with ACS. Therefore, this study supports the hypothesis that reduced n-3 FA tissue levels are a common and potentially modifiable link between depression and adverse CV outcomes.
Lymphokine production by T-cell clones after human bone marrow transplantation (1989)

T cells recovering after bone marrow transplantation (BMT) were analyzed for their phenotypic and functional features by two-color immunofluorescence and a high efficiency cloning technique. A predominance of cells co-expressing natural killer (NK)-related surface antigens, such as Leu 7 (CD57) and CD11b, was detected within both the CD4+ and CD8+ subsets from 5 months postgrafting onward. Such cells are virtually absent among normal circulating CD4+ cells and account for a minority (approximately 30%) of normal CD8+ cells. Postgrafting T cells representative of the whole range of NK-related antigen co-expression were selected from six patients for clonal analyses. In control subjects, 63% and 41% of the CD4+ and CD8+ clones, respectively, produced interleukin-2 (IL-2) whereas approximately 30% of either CD4+ or CD8+ control clones produced interferon (IFN)-gamma. At variance, and irrespective of their CD4+/CD8+ phenotype, lower proportions of BMT recipient-derived clones produced IL-2 (20% and 12%, respectively), whereas the majority of both CD4+ and CD8+ clones (75% and 71%, respectively) released high amounts of IFN-gamma. Purified populations of CD57+/CD11b+ v negative cells from two BMT recipients and two control subjects were cloned and subsequently evaluated for IL-2 and IFN-gamma production. CD57+/CD11b+ cell-derived clones were poor IL-2 producers in both normal subjects and BMT patients. In contrast, IL-2-producing clones were frequent (62% to 79%) among those derived from CD57-/CD11b- cells from normal subjects, whereas they were still represented at lower than normal proportions, ie, 25% to 41%, among clones generated from BMT recipients. CD57+/CD11b+ cells gave rise to comparably high proportions of IFN-gamma producing clones in both normal subjects and BMT recipients (approximately 80%). In contrast, IFN-gamma producing clones were approximately 25% to 50% of CD57-/CD11b- cell-derived clones in both normal subjects and BMT patients. Therefore, while the predominance of NK-related antigen-positive T cells may be predictive of poor IL-2 and high IFN-gamma production, the immune derangement in long-term BMT recipients is further enhanced by the finding that all T cells may be poor IL-2 producers. It is also suggested that IL-2 production is a preferential function of T cells that do not express CD57 and CD11b, whereas IFN-gamma production is attributable to T cells that express CD57 and CD11b.
Bis-diazeniumdiolates of Dialkyldiamines:  Enhanced Nitric Oxide Loading of Parent Diamines (2005)

[reaction: see text] The synthesis and characterization of a series of symmetric bis-dialkyldiamine-based diazeniumdiolates, RN[N(O)NO(-)Na(+)](CH(2))(x)()N[N(O)NO(-)Na(+)]R', are reported. Preparation of corresponding intramolecular diazeniumdiolates of the form RN[N(O)NO](-)(CH(2))(x)()NH(2)(+)R' with alkyl groups > (CH(2))(4)CH(3) have been shown previously to lack stability. In contrast, sodium-stabilized bis-diazeniumdiolates of such lipophilic species can be readily formed when these same diamines are reacted with NO in basic media. The resulting compounds release 4 mol of NO per mole of original diamine. This approach enables the synthesis of more lipophilic NO donors than previously possible.
Designing curriculum, teaching and assessment for a climate-changing world (2009)

Introduction/background: A large body of research now exists on the subject of what climate change will mean for healthcare needs. There are also calls for health education and training to better prepare health professionals for a climate-changing world. The keynote in this literature is the importance of adaptive practices for responding to climate change. It is known that health professionals will need to respond to a wide range of direct and indirect consequences of climate change, requiring not only content knowledge but also flexibility and responsiveness to diverse regional conditions as part of complex health problem-solving— adaptation. This will be particularly important in rural and remote education and training. However, little has been written exploring what this means for the ‘bread and butter’ practices of curriculum design, teaching and assessment. Purpose/objectives: This presentation examines how adaptive practices for climate change can be a part of education and training programs for health professionals. Issues for exploration/ideas for discussion: The presentation identifies clinical and non clinical dimensions of adaption for climate change, particularly as it relates to rural and remote health practice. It provides practical suggestions for designing curriculum, teaching and assessment that helps health professionals be adaptive in a climate-changing world. Using the education literature on best practice, as well as available models such as the Primary Curriculum document of the Australian College of Rural and Remote medicine (ACRRM) as a point of departure, it offers examples of competencies, teaching approaches, as well as assessment models, useful to ensuring health professionals can adapt to the new conditions brought by climate change. Conclusions: Meeting the challenges of climate change in health professional education and training will involve a questioning of some approaches to education and training and an embracing of others. The practical demands of designing curriculum, teaching and assessment that helps health professionals adapt to climate change will reinforce and extend existing knowledge of best practice in education and training.
Estimating software project effort using analogies (1997)

Accurate project effort prediction is an important goal for the software engineering community. To date most work has focused upon building algorithmic models of effort, for example COCOMO. These can be calibrated to local environments. We describe an alternative approach to estimation based upon the use of analogies. The underlying principle is to characterize projects in terms of features (for example, the number of interfaces, the development method or the size of the functional requirements document). Completed projects are stored and then the problem becomes one of finding the most similar projects to the one for which a prediction is required. Similarity is defined as Euclidean distance in n-dimensional space where n is the number of project features. Each dimension is standardized so all dimensions have equal weight. The known effort values of the nearest neighbors to the new project are then used as the basis for the prediction. The process is automated using a PC-based tool known as ANGEL. The method is validated on nine different industrial datasets (a total of 275 projects) and in all cases analogy outperforms algorithmic models based upon stepwise regression. From this work we argue that estimation by analogy is a viable technique that, at the very least, can be used by project managers to complement current estimation techniques.
Micro electret power generator (2003)

We present the first micromachined rotational electret power generator, linearized theoretical model of electret power generation, and novel method to produce uniformly charged electret. We also improved our previously developed (1996, 1999) thin film Teflon AF 1601-S electret technology with respect to dielectric thickness, charge uniformity, and processability. In demonstration, our prototype power generator successfully generated > 25/spl mu/W with electret thickness of 9/spl mu/m, effective charge density of -2.8/spl times/10/sup -4/C/m/sup 2/, and rotational speed of 4170RPM.
A Comparison of Learning Environments: All That Glitters (2013)

Computerized learning environments can be characterized by the amount of learner control supported during the learning process. This dimension can be viewed as a continuum ranging from minimal (e.g., rote or didactic environments) to almost complete learner control (e.g., discovery environments). Two differing perspectives, representing the ends of this continuum, have arisen in response to the issue of the most optimal learning environment to build in intelligent tutoring systems (ITS). One approach is to develop an environment containing assorted tools and allow the learner freedom to explore and learn, unfettered (e.g., Collins & Brown, 1988; Shute, Glaser, & Raghavan, 1989; White & Horowitz, 1987). Advocates of an opposing perspective argue that it is more efficacious to develop straightforward learning environments that do not permit “garden path” digressions (e.g., Anderson, Boyle & Reiser, 1985; Corbett & Anderson, 1989; Sleeman, Kelly, Martinak, Ward, & Moore, 1989). This disparity between the positions becomes more complicated because the issue is not just which is the better learning environment; but rather, which is the better environment for what type(s) of persons, a classic aptitude-treatment interaction question (Cronbach & Snow, 1977).
Pathogenesis of the earliest epithelial cell damage induced by mepirizole and cysteamine in the rat duodenum. (1989)

Mepirizole (200 mg/kg) and cysteamine (100 mg/kg) induced epithelial cell damage in the proximal duodenum of rats within 30 min after s.c. administration. The injury induced was severe 60 min later. Gastric acid secretion determined in intact animals was stimulated by these agents 30 and 60 min later when the intraluminal pH of the duodenum was significantly decreased. Duodenal blood flow was significantly decreased beginning 5 min after administration up to 60 min. Oral treatment with sodium bicarbonate (300 mg/kg), cimetidine (100 mg/kg), omeprazole or NC-1300 (gastric proton pump inhibitors, 30 mg/kg) and 16,16-dimethyl prostaglandin E2 (10 micrograms/kg) protected the epithelium from damage induced by the two duodenal ulcerogens. Epithelial cell damage in the duodenum in response to mepirizole and cysteamine appears to be related to the increased gastric acid secretion followed by lowered intraduodenal pH of the duodenum having decreased blood flow.
SOC Test Optimization with Compression-Technique Selection (2008)

The increasing test-data volumes needed for the testing of system-on-chip (SOC) lead to long test times and high memory requirements. We present an analysis to highlight the fact that the impact of a test-data compression technique on test time and compression ratio are method-dependant as well as TAM-width dependant. Therefore, we propose a technique where compression-technique selection is integrated with core wrapper design, test architecture design, and test scheduling to minimize the SOC test time and the test-data volume.
An approach to performance analysis of timestamp-driven synchronization mechanisms (1984)

In this paper we introduce a new analytical approach to modeling the performance of systems synchronized by timestamp mechanisms, including database systems. We define the virtual time - real time (T-V) plane, and an important kind of stochastic process that we call linear Poisson processes. We show how to calculate the rate of preemption (corresponding to the rate of abortion or rollback in concurrency control mechanisms) and the waiting time until last preemption (corresponding to commit time) for linear Poisson processes. Finally, we apply this theory, analyzing one example system synchronized by the Time Warp mechanism.

Nonvolatile Conjugates of Secondary Metabolites as Precursors of Varietal Grape Flavor Components (1989)

An examination of hydrolysates produced by glycosidase enzyme or pH 3.2 acid treatment of C18 reversed-phase isolates from juices of "non-floral" vitis vinifera vars. Chardonnay, Sauvignon Blanc and Semillon demonstrated that these grapes contain conjugated forms of monoterpenes, C13 norisoprenoids, and shikimic acid-derived metabolites. The volatile compounds obtained hydrolytically from the conjugates were produced in sufficient concentration to permit ready analysis by GC/MS. The products of pH 3.2 hydrolysis have sensory significance when assessed in a neutral wine. The study further develops the precursor analysis approach as a technique to facilitate research into varietally specific constituents of grapes.
On the Study of Generative Adversarial Networks for Cross-Lingual Voice Conversion (2019)

Cross-lingual voice conversion (VC) aims to convert the source speaker's voice to sound like that of the target speaker, when the source and target speakers speak different languages. In this paper, we propose to use Generative Adversarial Networks (GANs) for cross-lingual voice-conversion. We further the studies on Variational Autoencoding Wasserstein GAN (VAW-GAN) and cycle-consistent adversarial network (CycleGAN), that are known to be effective for mono-lingual voice conversion. As cross-lingual voice conversion needs to converts the voice across different phonetic system, it is more challenging than mono-lingual voice conversion. By using VAW-GAN and CycleGAN, we successfully convert the speaker identity while carrying over the source speaker's linguistic content. The proposed idea is unique in the sense that it neither relies on bilingual data and their alignment, nor any external process, such as ASR. Moreover, it works with limited amount of training data of any two languages. To our best knowledge, this is the first comprehensive study of Generative Adversarial Networks in cross-lingual voice conversion. In the experiments, we achieve high-quality converted voice, that performs equally well or better than mono-lingual voice conversion.
Quantitative coronary angiography with deformable spline models (1997)

Although current edge-following schemes can be very efficient in determining coronary boundaries, they may fail when the feature to be followed is disconnected (and the scheme is unable to bridge the discontinuity) or branch points exist where the best path to follow is indeterminate. In this paper, we present new deformable spline algorithms for determining vessel boundaries, and enhancing their centerline features. A bank of even and odd S-Gabor filter pairs of different orientations are convolved with vascular images in order to create an external snake energy field. Each filter pair will give maximum response to the segment of vessel having the same orientation as the filters. The resulting responses across filters of different orientations are combined to create an external energy field for snake optimization. Vessels are represented by B-Spline snakes, and are optimized on filter outputs with dynamic programming. The points of minimal constriction and the percent-diameter stenosis are determined from a computed vessel centerline. The system has been statistically validated using fixed stenosis and flexible-tube phantoms. It has also been validated on 20 coronary lesions with two independent operators, and has been tested for interoperator and intraoperator variability and reproducibility. The system has been found to be specially robust in complex images involving vessel branchings and incomplete contrast filling.
Intramolecular selectivity of the alkylation of substituted anilines by gaseous cations (1985)

The intramolecular selectivity of the electrophilic reactions of Et+, i-Pr+, and Me2F+ cations with substituted anilines, including m-toluidine, m-anisidine, and m- and p-fluoroaniline, has been investigated in the dilute gas state at pressures ranging from 100 to 720 torr by a radiolytic technique, complemented by chemical ionization mass spectrometry. The results indicate an appreciable kinetic bias for the nitrogen atom, leading to predominant N-methylation by Me2F+. The reactivity of the carbenium ions is complicated by the simultaneous Occurrence of proton transfer, in particular to the NH2 group, which increases the relative extent of ring alkylation. The positional selectivity is characterized, aside from the usual orienting effects of the substituents, by the enhanced reactivity of the ring positions ortho to an n-type substituent, irrespective of its activating or deactivating properties. The effect is traced to the preliminary formation of an electrostatic adduct between the aniline and the gaseous electrophile.
RETINITIS PIGMENTOSA PATHOLOGICAL FINDINGS IN TWO CASES (1956)

ALTHOUGH retinitis pigmentosa is a fairly common affection and an im- portant cause of blindness, relatively few cases have been examined histo- logically. Cogan (1950) found some twenty cases in the literature and himself described three more. The condition most commonly shows a recessive mode of inheritance (Sorsby, 1951), and all the cases so far des- cribed for which family histories are recorded appear to be of this type. '
A New 2.4GHz CMOS Low-Noise Amplifier with Automatic Gain Control (2006)

A new 2.4GHz CMOS low-noise amplifier with automatic gain control that provides an enhanced dynamic range of up to 40 dB over conventional low-noise amplifiers is proposed. The proposed low-noise amplifier automatically adjusts its voltage gain by monitoring the amplitude of its output voltage so as to achieve a large dynamic range. The proposed low- noise amplifier allows a receiver system to become adaptive to antenna array, waveguides, and transmission lines, as well as standard antenna signal powers. The amplifier provides a gain of over 35dB, a noise figure below 0.5dB, and reflection coefficient below -35dB at 2.4GHz. The transient time of the amplifier is approximately 23 <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">μs</i> with the variation of the input RF power of 30dBm.
Chlorogenic Acid Analogue S 3483: A Potent Competitive Inhibitor of the Hepatic and Renal Glucose-6-Phosphatase Systems (1998)

S 3483, a synthetic derivative of chlorogenic acid (CHL), was found to be a reversible, linear competitive inhibitor of the glucose-6-phosphatase (Glc-6-Pase) system in rat renal microsomes and rat and human liver microsomes. The Ki for S 3483 in rat liver microsomes (129 nM) is three orders of magnitude smaller than the Ki for CHL. S 3483 up to 100 microM had no effect on the Glc-6-Pase enzyme activity or on the system inorganic pyrophosphatase activity (i.e., on T2, the Pi/inorganic pyrophosphate transporter). Thus, like CHL, S 3483 appears to be a site-specific inhibitor of T1, the Glc-6-P transporter of renal and liver microsomes. The potency of S 3483 was unaffected when the ratio Vmax(T1):Vmax(enzyme) was altered over a 10-fold range by applying enzyme inhibition and selective inactivation of T1. The absence of T1-imposed rate restrictions on the potency of reversible T1 inhibitors contrasts markedly with the response of reversible Glc-6-Pase enzyme inhibitors, whose potency declines sharply as T1 becomes more rate controlling. The potency of S 3483, but not of CHL, decreased as the microsomal protein concentration in the assay medium was increased. This effect suggests that as the protein concentration was raised the concentration of T1 in the assay medium approached the order of magnitude of the Ki for S 3483. Thus, the microsomal content of T1 is likely to be on the order of 100 pmol/mg protein. S 3483 is the most potent inhibitor of the Glc-6-Pase system reported to date. It and other tight-binding inhibitors of T1 will provide useful new tools for investigating the molecular structure and physiology/pathology of the Glc-6-Pase system.

Synthesis, Characterization, and Electrochemical Studies of New π‐Extended Metalloporphyrins (2009)

Abstract A doubly fused porphyrin has been synthesized by two successive cyclization reactions. The first meso ‐phenyl group was fused by an intramolecular Cadogan reaction leading to an enamine‐functionalized porphyrin. After Vilsmeier–Haack formylation of the nickel enaminoporphyrin, an intramolecular Friedel–Crafts reaction followed by dehydration of the intermediate alcohol afforded the doubly fused aromatic nickel porphyrin, which could be demetalated. The free base and the copper and palladium porphyrins show extremely high absorbances in the 700–800 nm range. The palladium complex was a good catalyst for the oxidation of cholesterol with singlet oxygen, which makes this chromophore a potential candidate for photodynamic therapy.(© Wiley‐VCH Verlag GmbH & Co.
