A Three-Dimensional Warp-and-Woof Structure Interwoven by a Couple of Two-Dimensional Network Layers in the Crystal Structure of [<i>trans</i>-Cd(NH3)2{Ag(CN)2}2]<i>n</i> (1995)

Abstract Two sets of the two-dimensional [Cd-(NC-Ag-CN-Cd1⁄4)4]n network layers arrayed vertically to each other interpenetrate through every mesh without any direct chemical bonds to build up the three-dimensionally interwoven supramolecular structure of the title complex.
Postural change of IOP in normal persons and in patients with primary wide open-angle glaucoma and low-tension glaucoma. (1984)

The values of intraocular pressure (IOP) measurements by an Alcon pneumatic tonometer and a Goldmann applanation tonometer were found to be close, with a correlation coefficient of 0.92. Measured by the pneumatonograph the IOP after 30 minutes in the supine position was highest in normal persons, in patients with primary wide open-angle glaucoma and low-tension glaucoma. The greatest difference in IOP between subjects sitting and supine was observed in patients with low-tension glaucoma.
Distinct N‐glycan fucosylation potentials of three lepidopteran cell lines (1992)

The fucosyltransferase activities of three insect cell lines, MB-0503 (from Mamestra brassicae), BM-N (from Bombyx mori) and Sf-9 (from Spodoptera frugiperda), were investigated and compared with that of honeybee venom glands. Cell extracts and venom gland extracts were incubated with GDP-[14C]fucose and glycopeptides isolated from human IgG and from bovine fibrin. The labeled oligosaccharide products were released by peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase A, fluorescence marked with 2-aminopyridine and analyzed both by reversed-phase and size-fractionation HPLC. They were identified by their elution positions before and after exoglycosidase treatment in comparison with standard oligosaccharides. These experiments revealed distinct fucosylation potentials in the three cell lines tested. While MB-0503 cells, like honeybee venom glands, are able to transfer fucose into alpha 1-3 and alpha 1-6 linkage to the innermost N-acetylglucosamine, only alpha 1-6-fucosyl linkages were detected with BM-N and Sf-9 cells.
Fragilidad y redes sociales en personas no institucionalizadas mayores de 75 años: un estudio transversal (2020)

Objetivo: examinar la relación entre fragilidad y redes sociales en personas no institucionalizadas mayores de 75 años.Fundamento: la fragilidad tiene un impacto negativo en el envejecimiento exitoso. La baja actividad física, la inactividad y la movilidad restringida son factores de riesgo que aumentan la fragilidad en las personas mayores. Las relaciones sociales de las personas mayores tienen un efecto en la salud a través de mecanismos psicosociales e influyen en los estados psicológicos o cognitivos.Diseño: se realizó un estudio transversal utilizando un cuestionario en una muestra de 326 individuos mayores de 75 años en Castellón (España), durante 2015, y seleccionado mediante muestreo intencional.Método: El estudio se realizó en el contexto de un programa de análisis y prevención de fragilidad. Los datos fueron recolectados a través de un cuestionario adaptado de una encuesta realizada por FRALLE.Resultados: 12.9% de los encuestados no vieron a ninguno de sus hijos más de una vez al mes. El 42,6% no vio a ningún amigo más de una vez al mes. En términos de participación comunitaria, el 66.9% de la muestra no fue a ninguna asociación cultural o club; esta proporción fue mayor entre las mujeres (72.8%). El puntaje promedio para el índice de vínculos familiares es mayor entre los no frágiles (x̅ = 2.64) que los frágiles (x̅ = 2.41) (p = 0,000). Los resultados muestran una mayor posibilidad de fragilidad para las mujeres (OR = 2.128; IC 95% 1.179 - 3.840).Conclusión: las redes familiares y la diversidad de las redes sociales fueron menores entre las personas frágiles. Relevancia para la práctica clínica: conocer los factores que influyen en las redes sociales de los ancianos permitirá a las enfermeras implementar acciones que ayuden a reducir la fragilidad.
News Story Segmentation in Multiple Modalities (2009)

In this paper, we describe an approach to segmenting news video based on the perceived shift in content using features spanning multiple modalities.We investigate a number of multimedia features, which serve as potential indicators of a change in story in order to determine which are the most effective. The efficacy of our approach is demonstrated by the performance of our prototype, where a number of feature combinations demonstrate an up to 18% improvement in Window Diff score above that of other state of the art story segmenters. In our investigation, there was no, one, clearly superior feature, rather the best segmentation results occurred when there was synergy between multiple features.
Synthesis and in vitro antibacterial activity of thymol and carvacrol derivatives. (2010)

Fourteen esters of thymol and carvacrol were synthesized and characterized on the basis of spectral data. The NMR data for some of these are being given for the first time. The antibacterial activity screening of thymol, carvacrol and their esters were carried out against four Gram-positive (Streptococcus mutans MTCC 890, Staphylococcus aureus MTCC 96, Bacillus subtilis MTCC 121, Staphylococcus epidermidis MTCC 435) and one Gram-negative (Escherichia coli MTCC 723) bacteria. The enhancement in activity was noticed in the thymyl ester derivatives 4a-c (against S. mutans, B. subtilis and S. epidermidis) in comparison to thymol, whereas the carvacrol derivatives were found to be much less active than carvacrol.
Spinal Cord Stimulation and Cerebral Blood Flow: An Experimental Study (1994)

Spinal cord stimulation (SCS) affects peripheral, coronary and cerebral blood flow (CBF) in humans. In 1986 Meglio et al. [Appl Neurophysiol 1986;49:139-146] advocated a functional reversible sympathectomy as one of the mechanisms of SCS in man. An experimental animal model was developed to study SCS effects on CBF and to investigate the possible mechanisms. Twenty-one white New Zealand rabbits were anesthetized with Fluothane; spontaneous ventilation was permitted. A steady hemodynamic and metabolic state was maintained. A small cervical laminectomy was performed and an electrode (Medtronic Sigma 3483) was placed in the epidural space over the posterior spinal cord. Both common carotid arteries were exposed and external carotid arteries were ligated. In 3 animals, the cervical symapthetic trunk (CST) was exposed and wrapped with bipolar hook-stimulating electrodes. SCS was performed for 20 min with electrical square waves of 210 microseconds duration, 80 cycles/s, at 2/3 motor threshold intensity. CST stimulation was delivered for 1 min with the following parameters: 10 V, 10 cycles/s, 0.5 ms duration. CBF velocities of both internal carotid arteries were measured by using a CW Doppler (in all the animals) and electromagnetic flowmeter (in 2 animals), at rest, during sympathetic trunk stimulation, during SCS, during simultaneous SCS and CST stimulation. During SCS, an increase of CBF was detected in 11 rabbits (52.4%); a decrease was observed in two cases (9.5%). No change was detected in the remaining 8 animals (38%). CST stimulation induced a decrease of CBF in all animals. Electromagnetic flowmetry confirmed velocitometric findings in the 2 cases studied.(ABSTRACT TRUNCATED AT 250 WORDS)
Differential effects of vascular endothelial growth factor A isoforms in a mouse brain metastasis model of human melanoma. (2003)

We reported previously that vascular endothelial growth factor isoform A (VEGF-A) expression by Mel57 human melanoma cells led to tumor progression in a murine brain metastasis model in an angiogenesis-independent fashion by dilation of co-opted, pre-existing vessels and concomitant enhanced blood supply (B. Kusters et al., Cancer Res., 62: 341-345, 2002). Here, we compare the activities of the 121, 165, and 189 VEGF-A isoforms in this model by transfecting Mel57 cells with the respective cDNAs and by injecting the resulting stably transfected cell lines in the internal carotid arteries of nude mice (n = 10 for each isoform). Although the three isoforms had similar potency to induce endothelial cell proliferation, VEGF(121) expression did not result in sprouting angiogenesis but rather led to extensive vasodilation and increased permeability of pre-existing, predominantly peritumoral vessels. Sometimes, proliferating endothelial cells accumulated in vessel lumina, giving these a microvascular, glomeruloid, proliferation-like appearance. Expression of VEGF(165) or VEGF(189) was associated with induction of an intratumoral neovascular bed. In VEGF(165)-expressing tumors, daughter endothelial cells were distributed among newly formed vessels that were extensively dilated. This also occurred in VEGF(189) tumors, but there, vasodilation was less pronounced. Using contrast-enhanced magnetic resonance imaging, the different vascular phenotypes were visualized on characteristic radiological images. VEGF(165) expression was the most unfavorable of the three. Mice carrying VEGF(165) tumors became moribund earlier than those carrying VEGF(121)-expressing tumors (16 +/- 4 days versus 22 +/- 3 days). Our data demonstrate that VEGF-A isoforms differ in angiogenic properties that can be visualized by contrast-enhanced magnetic resonance imaging.
Effect of fluoxetine pretreatment on plasma and tissue concentrations of desipramine in rats. (1989)

Because of clinical reports that fluoxetine co-administration has led to increased blood concentrations of desipramine and adverse clinical effects in depressed patients treated with desipramine, we investigated the effect of fluoxetine on desipramine metabolism by rat liver microsomes in vitro and on blood and brain concentrations of desipramine in rats treated with desipramine. Fluoxetine caused a concentration-dependent inhibition of the 2-hydroxylation and N-demethylation of desipramine in vitro. Fluoxetine increased blood and brain concentrations of desipramine and prolonged the half-life of desipramine in blood and brain in rats in vivo. The inhibition of desipramine metabolism by fluoxetine probably led to the increased blood levels of desipramine in the clinical cases and may have contributed to the acceleration of cortical beta adrenoreceptor downregulation reported in rats when desipramine and fluoxetine were co-administered.
Chirality in guided-wave structures and printed-circuit antennas: theory and applications (1991)

Electromagnetic chirality, which describes the role of chirality or handeness in electromagnetics, is exhibited in chiral materials. Isotropic chiral materials can be described electromagnetically by the constitutive relations D = $\\varepsilon\\sb{\\rm c}$ E + i$\\xi\\sb{\\rm c}$ B and H = i$\\xi\\sb{\\rm c}$ E + B/$\\mu\\sb{\\rm c}$ where $\\varepsilon\\sb{\\rm c}$, $\\mu\\sb{\\rm c}$, and $\\xi\\sb{\\rm c}$ are the permittivity, permeability and chirality admittance of the medium, respectively. Here, we introduce the concept of chirality into guided-wave structures and printed-circuit antenna technology. We develop the theory of chirowaveguides which consist of conventional waveguides containing chiral materials. We apply this theory to the cases of perfectly conducting parallel-plate, circular, and rectangular chirowaveguides. Novel features such as mode bifurcation and hybrid modes are discussed. We then extend our analyses to waveguides with open boundaries and investigate the electromagnetic properties of grounded and ungrounded chiral slabs. In particular, we determine the modes of electromagnetic waves in a grounded chiral slab (surface-wave and radiation modes), and introduce sources to model chirostrip antennas which consist of microstrip antennas with their substrates and/or superstrates replaced by chiral layers. We investigate the canonical cases of a line and a dipole antennas on top of grounded chiral slabs and show that, under certain circumstances, the surface wave power for a line source can be reduced and the radiation efficiency increased. We also present the radiation properties of line and dipole chirostrip arrays and study the effect of chirality on the sidelobe levels of these arrays. We then consider the more realistic finite-length chirostrip antenna and investigate its radiation properties such as current distribution, radiation patterns, input impedance, bandwidth, efficiency and mutual coupling between two such antennas. We find that a compromise has to be made between a wider bandwidth and a lower efficiency as compared with the nonchiral case. We also show that, due to chirality, the main beam of the radiation pattern is rotated around the axis normal to the slab. We finally show that, when chiral materials are used for the substrates, the mutual coupling between two finite-length chirostrip antennas is generally reduced. A whole host of applications of chiral materials in guided-wave structures and microstrip antennas are also addressed.
Review: recent progress in low-temperature proton-conducting ceramics (2019)

Proton-conducting ceramics (PCCs) are of considerable interest for use in energy conversion and storage applications, electrochemical sensors, and separation membranes. PCCs that combine performance, efficiency, stability, and an ability to operate at low temperatures are particularly attractive. This review summarizes the recent progress made in the development of low-temperature proton-conducting ceramics (LT-PCCs), which are defined as operating in the temperature range of 25–400 °C. The structure of these ceramic materials, the characteristics of proton transport mechanisms, and the potential applications for LT-PCCs will be summarized with an emphasis on protonic conduction occurring at interfaces. Three temperature zones are defined in the LT-PCC operating regime based on the predominant proton transfer mechanism occurring in each zone. The variation in material properties, such as crystal structure, conductivity, microstructure, fabrication methods required to achieve the requisite grain size distribution, along with typical strategies pursued to enhance the proton conduction, is addressed. Finally, a perspective regarding applications of these materials to low-temperature solid oxide fuel cells, hydrogen separation membranes, and emerging areas in the nuclear industry including off-gas capture and isotopic separations is presented.

Cache-conscious frequent pattern mining on a modern processor (2005)

In this paper, we examine the performance of frequent pattern mining algorithms on a modern processor. A detailed performance study reveals that even the best frequent pattern mining implementations, with highly efficient memory managers, still grossly under-utilize a modern processor. The primary performance bottlenecks are poor data locality and low instruction level parallelism (ILP). We propose a cache-conscious prefix tree to address this problem. The resulting tree improves spatial locality and also enhances the benefits from hardware cache line prefetching. Furthermore, the design of this data structure allows the use of a novel tiling strategy to improve temporal locality. The result is an overall speedup of up to 3.2 when compared with state-of-the-art implementations. We then show how these algorithms can be improved further by realizing a non-naive thread-based decomposition that targets simultaneously multi-threaded processors. A key aspect of this decomposition is to ensure cache re-use between threads that are co-scheduled at a fine granularity. This optimization affords an additional speedup of 50%, resulting in an overall speedup of up to 4.8. To
Development of aptamers specific for potential diagnostic targets in Burkholderia pseudomallei (2008)

Improved diagnostic reagents would be of considerable benefit in enhancing the specificity and sensitivity of rapid assays for Burkholderia pseudomallei, the causative agent of melioidosis. The purpose of this work is to develop aptamers, high affinity RNA-based molecular recognition molecules, which could be used as reagents for identification of the whole organism in assays of biological samples. Data are presented demonstrating the purification of recombinant B. pseudomallei secreted or surface-exposed macromolecules, which have been expressed in Escherichia coli, and the initial stages of aptamer generation using these recombinant proteins. Future studies will focus upon the expansion of this methodology to include other target macromolecules located on or near the outer membrane of this organism.
Vascular effects of paclitaxel following drug-eluting balloon angioplasty in a porcine coronary model: the importance of excipients (2011)

Effective excipients are necessary to accomplish successful balloon facilitated paclitaxel delivery, which is associated with delayed vascular healing as a sign of successful drug transfer. The potential of DEBs to diminish restenosis following angioplasty may be insufficient in the absence of additional stents.

Clinical and Laboratory Studies of Combined Live Measles, Mumps, and Rubella Vaccines Using the RA 27/3 Rubella Virus (1980)

Eleven lots of combined bivalent and trivalent vaccines containing the measles (Moraten), mumps (Jeryl Lynn), and rubella (RA 2713) viruses gave satisfactory results in tests in initially seronegative children (measles, 493 children; mumps, 377; rubella, 586). There was no apparent suppression of antibody response against any of the viruses in the vaccines. The clinical reactions observed were mild and inconsequential. Substitution of the HPV 77-DE strain employed heretofore with the RA 27/3 is technically acceptable and offers the advantage of higher titer, slightly greater seroconversion rate, and more solid immunity against reinfection in nature.

Video multicast using a VSB-AM external modulator at 1.5 mu m (1991)

At 1.5 mu m VSB-AM video signal source is demonstrated using a balanced Mach-Zehnder external modulator. The source is a continuous wave Er-doped glass laser operating at 1.534 mu m. The predistortion network reduces the Mach-Zehnder third-order distortion level by 17-21 dB across the 330-450 MHz frequency band. The transmitter third order distortion level is better than 60 dBc for 4.0% modulation index per channel in a 20 channel system. A carrier-to-noise ratio of 54 dB was achieved at 0 dBm detected power. With 12.6 km of standard single-mode fiber (SMF) which has minimum dispersion near 1310 nm, no noticeable system carrier-to-noise ratio or composite second order distortion degradation are detected. Measurement with 10.5 km of distortion shifted fiber (DSF), which has minimum dispersion near 1550 nm, showed little carrier-to-noise degradation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Random Noise Produced by X-Ray Fluorescent Screens* (1968)

A theory is presented concerning the spatial light-energy fluctuation in a photographic emulsion placed in intimate contact with a fluorescent screen that is excited by x rays. For simplicity, the fluorescent screen is assumed to be irradiated with monoenergetic x rays. Formulas have been developed for the average light energy received by the emulsion, the autocorrelation function, and the Wiener spectral density associated with the fluctuation of light energy about the average value.For a linear, time-invariant electrical network, the transfer function can be determined by means of a white-noise input. Theoretical considerations indicate that an analogous method is not valid for fluorescent-screen–film systems. This point is illustrated only analytically for a homogeneous fluorescent screen which consists of a thin, but large, macrocrystal of calcium tungstate.The recording of the fluctuations of light energy as variations of optical density by the photographic film is discussed quantitatively.
