New method for quantitative mapping of metallic elements in tissue sections by electron probe microanalyser with wavelength dispersive spectrometers (2001)

In this paper, we have proposed a new method that gives quantitative distributions of metallic elements in a tissue section by electron probe microanalyser equipped with wavelength dispersive spectrometers. Its principal merit is the clear expression of element distribution with micrometer resolution in typically prepared section samples for routine histopathological diagnosis. By analysing thin standard films containing metallic atoms of interest, it was confirmed that the detection limit is about 1 x 10(6) atoms microm-2. This value corresponds to 100 microg g(-1) (dry weight) in case of tissue section of 2 microm thickness. Furthermore, for copper, iron and aluminium, the exact linear relationship between the amount of metallic atoms and the characteristic X-ray intensity was established in the range up to 15 x 10(6) atoms microm(-2). The element maps of tissue sections from patients with Wilson's disease proved that the copper levels in analysed areas were not homogeneous and indicated abnormal accumulation in some portions. These results confirmed the usefulness of this method for histopathological diagnosis.
Identification, Analysis, and Removal of Geosmin from Muddy-Flavored Trout (1974)

Geosmin has been isolated and identified, using gas-chromatographic, mass-spectrometric and organoleptic analysis, as the principal compound responsible for the muddy flavor in fish from various saline lakes in western Canada. A method for quantitative estimation of geosmin has been described and evaluated. Placing of muddy-flavored rainbow trout (Salmo gairdneri) in clean water resulted in reduction of flavor to the borderline level between 3 and 5 days, and of geosmin concentration from 1.1 to 0.3 μg/100 g of flesh in 14 days. The taste threshold level of geosmin was estimated to be 0.6 μg/100 g flesh.
Engineering phosphors for field emission displays (1999)

Factors affecting the synthesis and properties of a new generation of fine particle low voltage phosphors in field emission displays are reviewed. The morphology and particle size, the composition and stoichiometry, the stability, together with the nature and shape of the particle surface, all play important roles in the performance of the final phosphor. Initial new results from novel synthetic methodology are presented and discussed. Their implications in the light of the known literature point the way to the successful conclusion of the current thrust of phosphor research for good red, green, and blue low voltage, high definition phosphors.

Concurrent neuromechanical and functional gains following upper-extremity power training post-stroke (2013)

Functional and neuromechanical gains were greater following HYBRID vs. FPT. Improved stretch reflex modulation and increased neuromuscular activation indicate potent neural adaptations. Importantly, no deleterious consequences, including exacerbation of spasticity or musculoskeletal complaints, were associated with HYBRID. These results contribute to an evolving body of contemporary evidence regarding the efficacy of high-intensity training in neurorehabilitation and the physiological mechanisms that mediate neural recovery.
The first intron of the alpha 1(I) collagen gene contains several transcriptional regulatory elements. (1988)

The first intron of the human alpha 1(I) collagen gene contains a negatively acting element that inhibits transcription of the chloramphenicol acetyltransferase gene driven by either a collagen or an SV40 basal promoter (Bornstein, P., McKay, J., Morishima, J., Devarayalu, S., and Gelinas, R. E. (1987) Proc. Natl. Acad. Sci. U. S. A. 84, in press). We now find that this element is flanked by sequences that both neutralize the inhibitory effect and impart a net positive effect on transcription. A collagen-human growth hormone minigene was constructed in which varying lengths of the collagen intron were retained. Plasmids were transfected into chick tendon fibroblasts, and transcriptional activity was measured by solution hybridization with an antisense RNA probe. The presence of the intact intronic sequence stimulated transcription by a factor of 2-3-fold in comparison with intron-deleted plasmids. However, the isolated negatively acting element inhibited transcription by a factor of 15-20-fold. Surprisingly, this effect was markedly orientation-dependent. Intronic segments flanking the negatively acting element stimulated transcription both when cloned 5' to the collagen promoter in chloramphenicol acetyltransferase-based plasmids and 3' in collagen-human growth hormone constructions. We conclude that expression of the alpha 1(I) collagen gene is controlled by several intronic elements that function coordinately with 5'-flanking and promoter elements.

Cyclic Nucleotide Phosphodiesterase Activity in Human Peripheral Blood Lymphocytes and Monocytes (1979)

cAMP and cGMP phosphodiesterase (PDE) activity was assayed in human peripheral blood lymphocytes purified by isopycnic centrifugation as well as in lymphocyte preparations further purified to remove contaminating platelets and monocytes. The 16,000 X G supernatant from sonicates of each of these cell preparations contained two hydrolytic activities for cAMP with apparent Km of 1.1 to 2.5 microM and 33 to 66 microM, and a single hydrolytic activity for cGMP with an apparent Km of 6 to 25 microM. When lymphocytes were disrupted by Dounce homogenization, there was only a single, low Km cAMP PDE activity in the homogenate; however, the 16,000 X G supernatant demonstrated 2 Km similar to that seen in sonicated lymphocytes. Treatment of the Dounce preparations with 0.5% Triton X-100 or 1.0% NP-40 converted these preparations to activities similar to those seen in sonicated preparations. cGMP hydrolytic activity was low or absent in the Dounce preparations and was not altered by centrifugation; however, it was markedly enhanced by detergent extraction. These data indicate that human peripheral blood lymphocytes and monocytes have PDE activities similar to those seen in other tissues.
SSL-Based Lightweight Security of IP-Based Wireless Sensor Networks (2009)

IP-based wireless sensor networks (IP-WSN) are popularly recognized as a global sensor networks infrastructure by combining IPv6 technology with wireless sensor networks (WSN). However, IP-WSN, currently, does not provide security because it is commonly recognized that it is a big burden for IP-WSN to adapt Internet's dominant security protocol. We suggest a security protocol for IP-WSN based on Secure Sockets Layer (SSL). We have developed IP-WSN sensor node hardware with 16-bit MSP430 MCU including 116 KB Flash and 8 KB RAM, and implemented IP-WSN software stack and lightweight SSL components. The resource consumption is around 64 KB of Flash and 7 KB of RAM when it is used that ECC for key-exchange and authentication, RC4 for data encryption, and MD5 for hashing. And it takes total 2 s for a full SSL handshake and a 127 bytes packet transfer. It can make IP-WSN secure and be used for the public and private services such as military observation, healthcare, and home-network.
Uptake and Utilization of Sugars in Cultured Rice Cells (1988)

Suspension cultured cells of rice (Oryza sativa) were grown in a medium containing sucrose. Sucrose was rapidly hydrolyzed extracellularly in the early stage of subculture with a concomitant decrease in the medium pH. The hydrolysis may be due to cell wall associated acid invertase and may be promoted by acidification of the medium. The resulting glucose and fructose seemed to be utilized equally. The cells grown on either sucrose, glucose or fructose contained each of these sugars and possessed cell wall associated invertase activity. Protoplasts prepared by cell wall degrading enzymes utilized preferentially glucose or fructose rather than sucrose. These results suggest that exogenous sucrose is hydrolyzed by the cell wall associated invertase to hexoses, which are then taken up and metabolized.
Studies of T- and B-Lymphocytes in Patients with Connective Tissue Diseases (1973)

Peripheral blood lymphocytes from normal subjects as well as patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and active tuberculosis were studied for the relative distribution of bone marrow-derived lymphocytes (B-cells) and thymic-derived T-cells. B-cells were identified by direct immunofluorescence of surface Ig markers; T-cells were studied using rabbit antisera to pooled human fetal thymocytes absorbed with chronic lymphatic leukemia lymphocytes as a source of B-cells. In normal subjects, the sum of percentages of peripheral blood lymphocytes staining for surface Ig (B-cells) plus the percentage of cells staining with the absorbed antithymocyte antiserum closely approximated 100%. The mean value for percent B-cells among 51 normals tested was 22.9%+/-7.1; mean T-cells value was 75.3+/-13.95%. T-cell-specific antiserum stained 18% of normal human bone marrow lymphocytes, 42.5% of lymphocytes from normal spleens, and 98% of cells obtained from thoracic duct drainage of patients with RA. Specificity of antihuman thymocyte antiserum appeared to depend on the use of living cells. When patients with RA were examined, a wide range (14-98%) of peripheral blood T-cell values was found. Values for low percentages of peripheral blood T-cells appeared to correlate to some extent with severe clinical disease. In 11 of 36 RA patients, the sum of identifiable B- plus T-cells accounted for only 34-55% of peripheral blood lymphocytes. The identity of the remaining "null" cells could not be identified.3 of 24 SLE patients studied showed low percentages of peripheral blood T-cells, but no correlation could be drawn between T- to B-cell ratios and clinical disease activity. Among 21 patients with active tuberculosis, one had a low value for identifiable T-cells. No significant differences from normals in range or proportion of B-cells was identified in patients with active tuberculous infection.
Evaluation on determination of iodine in coal by energy dispersive X-ray fluorescence (2005)

A quick and inexpensive method of relative high iodine determination from coal samples was evaluated. Energy dispersive X-ray fluorescence (EDXRF) provided a detection limit of about 14 ppm (3 times of standard deviations of the blank sample), without any complex sample preparation. An analytical relative standard deviation of 16% was readily attainable for coal samples. Under optimum conditions, coal samples with iodine concentrations higher than 5 ppm can be determined using this EDXRF method. For the time being, due to the general iodine concentrations of coal samples lower than 5 ppm, except for some high iodine content coal, this method can not effectively been used for iodine determination. More work needed to meet the requirement of determination of iodine from coal samples for this method.
Modular Multilevel Converter with tuned filter: Operational possibility and simple control (2014)

The Modular Multilevel Converter (MMC) is an emerging topology which is being used over a range of applications. There are a number of attractive features of the converter compared to other converter topologies currently available. But, the charge balance in the floating capacitor is achieved at fundamental frequency. This is a challenge if the converter is to be used in low frequency application or DC to DC conversion. To overcome this problem, injection of a high frequency common mode voltage has been studied. These methods result in high circulating currents which increase losses in the switches. An alternative method based on the principle of orthogonal power flow theory has also been proposed. This paper gives operational possibility and simple control of such a converter.

Transport, stability, and biological activity of resveratrol (2011)

Numerous studies have reported interesting properties of trans-resveratrol, a phytoalexin, as a preventive agent of several important pathologies: vascular diseases, cancers, viral infections, and neurodegenerative processes. These beneficial effects of resveratrol have been supported by observations at the cellular and molecular levels in both cellular and in vivo models, but the cellular fate of resveratrol remains unclear. We suggest here that resveratrol uptake, metabolism, and stability of the parent molecule could influence the biological effects of resveratrol. It appears that resveratrol stability involves redox reactions and biotransformation that influence its antioxidant properties. Resveratrol's pharmacokinetics and metabolism represent other important issues, notably, the putative effects of its metabolites on pathology models. For example, some metabolites, mainly sulfate-conjugated resveratrol, show biological effects in cellular models. The modifications of resveratrol stability, chemical structure, and metabolism could change its cellular and molecular targets and could be crucial for improving or decreasing its chemopreventive properties.

Efficient Cyclic Prefix Reconstruction for Coded OFDM Systems (2004)

This letter describes an improved method to mitigate interference when the cyclic prefix is not sufficient for coded orthogonal frequency-division multiplexing (OFDM) systems. The proposed method, based on the residual intersymbol interference cancellation (RISIC), efficiently restores the cyclicity of the ith received symbol by adding the weighted (i+1)th received symbol to the ith received symbol. Simulation results show that the proposed scheme outperforms the conventional RISIC in the symbol error rate even when the channel impulse response is longer than a half of the symbol duration.

Influence of 1-methylcyclopropene on Ripening, Storage Life, and Volatile Production by d'Anjou cv. Pear Fruit (2003)

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene production compared to untreated controls. Fruit quality changes were delayed following 1-MCP treatment, as was development of superficial scald and peel yellowing. The duration of 1-MCP-induced responses was dependent on 1-MCP treatment concentration. When 1-MCP-treated fruit began to ripen, softening and production of volatile compounds proceeded similar to that of untreated fruit. Post-storage ethylene exposure did not consistently stimulate ripening of fruit previously treated with 1-MCP. Efficacy of ethylene treatment depended on 1-MCP concentration and storage duration.
Time-domain spectroscopy in the mid-infrared (2014)

When coupled to characteristic, fingerprint vibrational and rotational motions of molecules, an electromagnetic field with an appropriate frequency and waveform offers a highly sensitive, highly informative probe, enabling chemically specific studies on a broad class of systems in physics, chemistry, biology, geosciences, and medicine. The frequencies of these signature molecular modes, however, lie in a region where accurate spectroscopic measurements are extremely difficult because of the lack of efficient detectors and spectrometers. Here, we show that, with a combination of advanced ultrafast technologies and nonlinear-optical waveform characterization, time-domain techniques can be advantageously extended to the metrology of fundamental molecular motions in the mid-infrared. In our scheme, the spectral modulation of ultrashort mid-infrared pulses, induced by rovibrational motions of molecules, gives rise to interfering coherent dark waveforms in the time domain. These high-visibility interference patterns can be read out by cross-correlation frequency-resolved gating of the field in the visible generated through ultrabroadband four-wave mixing in a gas phase.
Structure frame-based model management system (1989)

A relatively unexplored area of model management systems research is the automatic construction of algorithms to solve a given model. In order to construct or suggest an appropriate algorithm, it is necessary to analyze and identify the structure of the given model. In this dissertation, we present an automatic procedure for identifying the structures of mathematical programming models expressed in algebraic form. We have developed techniques for extracting structural (syntactic and semantic) information from the algebraic form, techniques for storing this structural information, and finally, techniques for analyzing this information to identify the problem that the model represents. Storing and identifying a model by its structural information makes it possible to automatically suggest an appropriate algorithm for solving the model. We demonstrate the practicality of our approach with a prototype implementation called the Structure Frame based Model Management System.
