Colistin Resistance Mechanisms in Klebsiella pneumoniae Strains from Taiwan (2015)

Colistin is one of the antibiotics of last resort for the treatment of carbapenem-resistant Klebsiella pneumoniae infection. This study showed that capsular type K64 (50%) and ST11 (53.9%) are the prevalent capsular and sequence types in the colistin-resistant strains in Taiwan. The interruption of transcripts (38.5%) and amino acid mutation (15.4%) in mgrB are the major mechanisms contributing to colistin resistance. In addition, novel single amino acid changes in MgrB (Stop48Tyr) and PhoQ (Leu26Pro) were observed to contribute to colistin resistance.

High Amounts of Total and Extracellular Vesicle‐Derived Soluble HLA‐G are Associated with HLA‐G 14‐bp Deletion Variant in Women with Embryo Implantation Failure (2016)

The high expression of sHLA-Gtot and sHLA-GEV , together with the presence of the 14-bp deletion allele, might be involved in implantation failure.
Biofilms and Biocomplexity (2007)

Biofilms are receiving attention as never before, reflecting our increasing awareness of their impact on health, the environment, industrial processes, and natural and manmade materials. Problems associated with biofilms cost the United States billions of dollars every year in energy losses, equipment damage, product contamination, and the management of infections. Biofilms are implicated in more than 80% of chronic inflammatory and infectious diseases caused by bacteria, including otitis media, endocarditis, gastrointestinal ulcers, infections of the urinary tract, and pulmonary infections in cystic fibrosis (CF) patients.
Comparison of Si−O−C Interfacial Bonding of Alcohols and Aldehydes on Si(111) Formed from Dilute Solution with Ultraviolet Irradiation (2004)

Aliphatic alcohols and aldehydes were reacted with the Si(111)-H surface to form Si-O-C interfacial bonds from dilute solution by using ultraviolet light. The resulting monolayers were characterized by using transmission infrared spectroscopy, spectroscopic ellipsometry, and contact angle measurements. The effect of different solvents on monolayer quality is presented. The best monolayers were formed from CH(2)Cl(2). The optimized monolayers were thoroughly characterized to determine the film structure and monolayer stability. The UV-promoted, alcohol-functionalized, and aldehyde-functionalized monolayers are of comparable quality to those previously prepared by other means. Although both molecules are tethered through a Si-O-C bond, the film reactivity is distinctly different with the aldehyde films being more chemically resistant. The differences in chemical reactivity, vibrational spectra, hydrophobicity, and ellipsometric thickness between the alcohol and aldehyde monolayers are attributed to a difference in molecular coverage and monolayer formation.

Comparison of UHF antenna and VHF capacitor PD detection measurements from turbine generator stator windings (2013)

On-line partial discharge (PD) measurements are widely used to detect stator winding insulation problems. The most widely applied measurement method uses 80 pF capacitors to detect the PD in the VHF (30-300 MHz) frequency range. However, there are more than 1000 large turbine generators equipped with a UHF antenna called the stator slot coupler (SSC). The SSC method operates in the frequency range 10-1000 MHz. In several cases both PD measuring systems were installed on the same generator. This paper compares the results from 13 generators that have both the VHF and UHF PD measurement systems. In some cases the correlation between the systems is good. However, there are some situations where one system indicates high PD is present and the other does not. This is presumably caused by the differences in pulse attenuation that occur in the two frequency ranges and the influence of high level sparking noise at the machine terminals, to which the capacitive sensors are preferentially sensitive.
Studies on Optically Active Amino Acids. X. Studies on α-Alkyl-α-amino Acids. V. Absolute Configuration of Biochemically Active (-)-α-Methyl-3, 4-dihydroxyphenylalanine (1966)

The absolute configuration of biologically active (-)-α-methyl-3, 4-dihydroxyphenylalanine has been elucidated to be L-or S-configuration by the chemical correlation with (+)-α-methylaspartic acid, whose absolute configuration was confirmed in the previous report. Preriminary examinations using racemic compounds were also described.
Mechanism of <i>In vitro</i> Pancreatic Cancer Cell Growth Inhibition by Melanoma Differentiation–Associated Gene-7/Interleukin-24 and Perillyl Alcohol (2008)

The death rate for pancreatic cancer approximates the number of new cases each year, and when diagnosed, current therapeutic regimens provide little benefit in extending patient survival. These dire statistics necessitate the development of enhanced single or combinatorial therapies to decrease the pathogenesis of this invariably fatal disease. Melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24) is a potent cancer gene therapeutic because of its broad-spectrum cancer-specific apoptosis-inducing properties as well as its multipronged indirect antitumor activities. However, pancreatic cancer cells show inherent resistance to mda-7/IL-24 that is caused by a block of translation of mda-7/IL-24 mRNA in these tumor cells. We now reveal that a dietary agent perillyl alcohol (POH) in combination with Ad.mda-7 efficiently reverses the mda-7/IL-24 "protein translational block" by inducing reactive oxygen species, thereby resulting in mda-7/IL-24 protein production, growth suppression, and apoptosis. Pharmacologic inhibitor and small interfering RNA studies identify xanthine oxidase as a major source of superoxide radical production causing these toxic effects. Because both POH and Ad.mda-7 are being evaluated in clinical trials, combining a dietary agent and a virally delivered therapeutic cytokine provides an innovative approach for potentially treating human pancreatic cancer.
Chemistry of Phosphorus in Soils (2005)

Much modern soil chemistry and soil management addresses the balance between sustainable agricultural practices and protection of the environment. Achieving production and environmental goals for soil phosphorus (P) management begins with an understanding of how these goals are related to the soil P cycle, the chemical and biochemical processes that control the forms, biological availability, and mobility of soil P. The importance of advancing one's understanding of mineral dissolution and precipitation to P bioavailability and mobility in soils can be easily illustrated. Based on one's understanding of soil P chemistry and the processes by which P is transported from soil to water, it is relatively straightforward to outline strategies for reducing P losses from the landscape. Sharpley et al. demonstrated the relationship between soil cover, soil erosion, and, consequently, total P losses from natural runoff events in Texas and Oklahoma.
Coordinating Text and Graphics in Explanation Generation (1989)

To generate multimedia explanations, a system must be able to coordinate the use of different media in a single explanation. In this paper, we present an architecture that we have developed for COMET (COordinated Multimedia Explanation Testbed), a system that generates directions for equipment maintenance and repair, and we show how it addresses the coordination problem. In particular, we focus on the use of a single content planner that produces a common content description used by multiple media-specific generators, a media coordinator that makes a fine-grained division of information between media, and bidirectional interaction between media-specific generators to allow influence across media.
Conjugated polyene fatty acids as fluorescent probes: synthetic phospholipid membrane studies (1977)

The preparation of polyene fatty acid membrane probes cis- and trans-parinaric acid and parinaroylphosphatidylcholines and their use in studies of several one- and two- component lipid systems are described. The fluorescence quantum yield of trans-parinaric acid in dipalmitoylphosphatidylcholine at 20 degrees C is approximately 0.3; the quantum yield in aqueous solution is negligibly small. Thermal-phase transitions in single-component phospholipid dispersions are monitored with absorption and fluorescence excitation peak position, fluorescence intensity, lifetime, and polarization. The transition temperatures observed are consistent with previous determinations. Shifts in the absorption peak position are related to the bilayer expansion as it undergoes the gel to liquid-crystalline transition, while fluorescence depolarization provides semiquantitative information concerning molecular motion of the probe in the bilayer. A long fluorescence lifetime component is observed for parinaric acid in the solid phase (up to 50 ns), and a short lifetime component is observed (ca. 5 ns) in the fluid phase of dipalmitoylphosphatidylcholine; both lifetime components are observed in the transition region. In most phospholipids, cis-parinaric acid detects the melting transition at about 1 degree C lower than trans-parinaric acid. Partitioning experiments involving mixed populations of phospholipid vesicles show that trans-parinaric acid preferentially associates with solid-phase lipids, while cis-parinaric acid shows a more equal distribution between solid and fluid lipids. The binding of cis-parinaric acid to dipalmitoylphosphatidylcholine at 25 degrees C is described as partitioning of parinaric acid between lipid vesicles and the aqueous phase with a partition coefficient of 5 X 10(5). Several rates are observed in the binding process which are interpreted as rapid outer monolayer uptake and a much slower process of interlamellar exchange. The phase diagram of the binary lipid mixture dipalmitoylphosphatidylcholine-dipalmitoylphosphatidylethanolamine has also been examined and found to be essentially identical to the one constructed using a nitroxide probe.
Glucose catabolism in African trypanosomes. Evidence that the terminal step is catalyzed by a pyruvate transporter capable of facilitating uptake of toxic analogs. (1993)

The protozoan parasite Trypanosoma brucei derives its metabolic energy exclusively from a unique type of glycolysis in which pyruvate derived from glucose catabolism is released into the host bloodstream. In this study, this terminal metabolic step has been examined in detail. Pyruvate release from trypanosomal cells supplied with glucose is very rapid, proceeding with an apparent Vmax of 214 nmol x min-1 x mg-1. Counterflow experiments with [14C]pyruvate demonstrate that this metabolic end product can be taken up by actively metabolizing cells consistent with the presence of a plasma membrane transporter. The findings that [14C] acetate exhibits a much lower capacity for cell entry and that the structural analog alpha-cyano-3-hydroxycinnamic acid inhibits pyruvate release provide additional support for the presence of a pyruvate transporter. The substrate analog and alkylating agent 3-bromopyruvate inhibits completely both cell motility and pyruvate release. Surprisingly, however, it is a poor inhibitor of pyruvate transport per se. Rather, its preferential site of action and that of iodoacetic acid were identified by radiolabeling studies and microsequence analysis as glyceraldehyde-3-phosphate dehydrogenase. In extending these studies, 3-bromopyruvate was found to be over 20 times less effective in inhibiting glyceraldehyde-3-phosphate dehydrogenase in intact erythrocytes than in trypanosomal cells. However, in sonicated preparations from both cell types, the enzyme exhibits nearly identical sensitivities to inhibition by 3-bromopyruvate. Experiments reported here provide the first direct evidence that pyruvate release in African trypanosomes is catalyzed by a specific transport system and implicate this transporter as a vehicle for delivering toxic alkylating agents into trypanosomal cells.
Subjective Validation of Perception Properties in Binaural Sound Reproduction Systems (2002)

In general hearing tests are necessary to assess the properties of spatialisation systems. To speed up the procedure of testing different system parameters an objective model of localisation in binaural sound reproduction system is introduced [7]. In the following the localisation properties of an auditory system based on playback via head phones is investigated. Therefore a new design for the experiment setup to investigate the perception of virtual sources is introduced. This paper reports the subjective validation of the objective model by informal listening tests. In addition to the localisation and localisation blur further properties are evaluated. Significant differences between different system setups are studied and depicted. 0
High frequency radiation from truncated arrays of filamentary sources on a dielectric slab (2002)

Previously explored radiation phenomenologies pertaining to individual line sources on a dielectric slab and to finite arrays of line sources in free space are combined to synthesize and parametrize radiation from finite line source arrays located on a dielectric slab surface. From rigorous analysis and subsequent high frequency asymptotics for the prototype periodic case with linear interelement phasing, the authors obtain an observable-based parametrization (OBP) which connects features in reference data with structural features of the (slab)-(line array) configuration via wave processes with different physical content. The OBP is derived by applying the Poisson summation formula to collectively restructuring leads to fields which are parametrized in terms of Floquet mode (FM) beams, slab-guided leaky modes (LM) peaked by phase matching to the truncated FM, and edge diffractions from the ends of the truncated array. The OBP algorithm is validated by comparison with numerical reference data, and the parametrization provides choices for design and classification.
Interaction of Crude and Pure Chorionic Gonadotropin with the Thyrotropin Receptor (1980)

The effect of crude and pure hCG preparations on bovine TSH (bTSH) binding to its receptor was investigated in an attempt to characterize further the intrinsic thyrotropic activity of hCG. In a TSH radioreceptorassay with bovine thyroid membranes, performed at 4 C without NaCl in the incubation medium, the cross-reactivity of a crude hCG preparation was 90% relative to unlabeled bTSH, whereas that of pure hCG and its subunits was below 0.01%. By Sephadex G-100 chromatography, the substances in crude hCG that displayed TSH binding inhibitory activity at 4 C exhibited great heterogeneity, with an apparent molecular size range of 6,000-70,000 daltons. No specific peaks of TSH binding inhibitory substances were observed in the elution region of hCG, TSH, or molar or chorionic TSH, and most of the inhibitory substances had apparent molecular sizes smaller than any known TSH. When the radioreceptorassay was performed under progressively more physiological conditions by raising the temperature to 37 C and adding NaCl to the incubation buffer, the crossreactivity of crude and pure hCG relative to bTSH fell to 0.003- 0.005% both with bovine and human thyroid membranes. The similar effects of crude and pure hCG under near physiological incubation conditions suggested that the active substance in the crude hCG preparation was indeed hCG, whereas the effect of the other substances in the preparation had been abolished. Under such conditions, no cross-reactivity of hCG subunits was observed, whereas the cross-reactivity of human TSH was 10%, that of human LH was 0.3%, and that of human FSH was 0.1% relative to bTSH. Based on the TSH radioreceptorassay performed under near physiological incubation conditions, resulting in maximal TSH sensitivity and specificity, the thyrotropic activity of 1 IU (gonadotropic activity) of hCG is thus equivalent to 0.05-0.08 juIU bTSH.

The Significance of Mediastinal Emphysema (1946)

SPONTANEOUS mediastinal emphysema is now a well recognized clinical entity to which considerable attention has been called. Although Hamman1 enumerated several routes by which air reaches the mediastinum, the finding of extensive mediastinal and subcutaneous emphysema may at times be too readily attributed to this relatively benign disorder and a serious underlying disease overlooked. It is the purpose of this paper to call attention to that possibility by presenting 2 cases. In Case 1 spontaneous mediastinal emphysema occurred twice, and at the time of recurrence mediastinal decompression became necessary. In Case 2 extensive mediastinal and subcutaneous emphysema was dependent on . . .
Pregnant women with chronic hypertension and superimposed pre‐eclampsia have high cerebral perfusion pressure (2001)

Superimposed pre-eclampsia is associated with significantly higher cerebral perfusion pressure measurements compared with women with uncomplicated chronic hypertension. This is not directly related to a higher blood pressure. The difference in cerebral perfusion pressure may be used to speculate upon the pathophysiology of the increased risk for eclampsia seen in patients with superimposed pre-eclampsia.
Search for circular polarization of HCN maser emission in CIT 6 (1989)

A search has been made for circular polarization of HCN maser emission in the circumstellar envelope of the carbon star CIT 6, using the 14 m FCRAO telescope. The emission has been found to be circularly unpolarized, with a 3 sigma upper limit of about 3 percent. The absence of circular polarization, together with relatively strong linear polarization detected previously, suggests a situation with the stimulated emission rate far less than the magnetic splitting far less than the line width of maser emission. The intensity of the line, as well as the degree and position angle of linear polarization, have been found to be constant on a time scale of 1 yr.

Fractal Descriptors Based on Fourier Spectrum Applied to Texture\n Analysis (2012)

This work proposes the development and study of a novel technique for the\ngeneration of fractal descriptors used in texture analysis. The novel\ndescriptors are obtained from a multiscale transform applied to the Fourier\ntechnique of fractal dimension calculus. The power spectrum of the Fourier\ntransform of the image is plotted against the frequency in a log- log scale and\na multiscale transform is applied to this curve. The obtained values are taken\nas the fractal descriptors of the image. The validation of the propose is\nperformed by the use of the descriptors for the classification of a dataset of\ntexture images whose real classes are previously known. The classification\nprecision is compared to other fractal descriptors known in the literature. The\nresults confirm the efficiency of the proposed method.\n
