Induction and Regulation of Heat-Shock Gene Expression by an Amino Acid Analog in Soybean Seedlings (1996)

The effect of the proline analog azetidine-2-carboxylic acid (Aze) on the induction and the regulation of heat-shock (HS) mRNA accumulation and heat-shock protein (HSP) synthesis in soybean (Glycine max) seedlings was studied. Treatment with Aze elicited an HS-like response at the normal growth temperature, 28[deg]C, with seven of nine HS cDNA clones tested. Two cDNA clones, Gm-Hsp22.5 and pFS2033, share 78% identity; however, transcripts hybridizing to GmHsp22.5 but not pFS2033 accumulated with Aze treatment at 28[deg]C. Substantial incorporation of radioactive amino acid into high molecular weight HSPs but not low molecular weight HSPs was observed in vivo during Aze treatment at 28[deg]C. Low molecular weight HSPs were detected using antibodies raised against an abundant member of low molecular weight class I HSPs, indicating that low molecular weight HSPs were synthesized at normal growth temperatures during Aze treatment despite a lack of substantial in vivo radioactive amino acid incorporation. In summary, Aze treatment induced accumulation of most but not all HS mRNAs and HSPs in soybean seedlings; the observations presented here suggest differential regulation among various HS genes at the transcriptional and posttranscriptional levels.
Percutaneous laser disk decompression: a review of the literature. (2006)

Sciatica, which is usually caused by herniation of an intervertebral disk, is a common problem with an annual incidence of 5 per 1000.[1][1], [2][2] In 60%–80% of patients experiencing their first episode of radicular pain, the symptoms recede to a nondisabling level within a period of 6 weeks.[2
LAW: A Workbench for Approximate Pattern Matching in Relational Data (2003)

Pattern matching for intelligence organizations is a challenging problem. The data sets are large and noisy, and there is a flexible and constantly changing notion of what constitutes a match. We are developing the Link Analysis Workbench (LAW) to assist an expert user in the intelligence community in creating and maintaining patterns, matching those patterns against a large collection of relational data, and manipulating partial results.
Experimental Evaluation of the Lateral-Order Distribution in Cellulose (1957)

The lack of agreement among various crystallinity and accessibility methods for cellu losic materials is explained in terms of the lateral-order distribution concept. A new definition of the order function is proposed which is more in keeping with recent infrared evidence showing that celluloses differ in distribution of hydrogen bond strengths rather than in actual number of hydrogen bonds. Some of the physical and chemical methods which can give empirical-order distribu tion information for native and regenerated samples are reviewed critically and some data are compared with results based on conventional crystalline-amorphous delineation.
Somatic embryogenesis and plant regeneration in Gossypium hirsutum L. (1985)

Regeneration of Gossypium hirsutum L. has been a much sought-after goal that would make feasible the use of somaclonal variation and gene manipulation for improvement of existing breeding lines. This study delineates a protocol for consistently regenerating G. hirsutum cv Coker 312.\n\nOptimal media for induction of somatic embryogenesis from mature and immature tissues of G. hirsutum L. cv Coker 312 has been determined. Explants of three-day seedlings form somatic embryos in 100% of cultures when treated with 0.1 mg/1 2,4-dichlorophenoxy acetic acid plus 0.5 mg/1 kinetin. The apical region of the seedling also responds 100% to 0.5 mg/1 napthaleneacetic acid plus 0.5 mg/1 kinetin. Mature tissues are more recalcitrant, forming somatic embryos on a limited number of treatments. Stem tissue is most readily induced by 2 mg/1 napthaleneacetic acid plus 0.1 mg/1 kinetin, whereas leaf tissue responds efficiently to 0.1 mg/1 2,4-dichlorophenoxy acetic acid plus 1.0 mg/1 2 iso-pentyl adenine or 1.0 mg/1 napthaleneacetic acid plus 0.5 mg/1 2 iso-pentyl adenine.\n\nEmbryogenic cell suspensions have been established and maintained by serial subculture in Murashige and Skoog basal medium (MS). Globular embryos develop normally when plated on solid medium containing basal MS medium. If subcultured to liquid MS basal medium in total darkness, globular embryos complete development, although cotyledons are less expanded and more vitreous than those on solid medium.\n\nA critical density of cells is required for embryo development in cell suspension. Addition of equimolar concentrations (10- 7M ) of abscisic acid, gibberellic acid, and kinetin enhances globular embryo proliferation, but normal development is suppressed. Glutamine enhances both embryo proliferation and development. Light plays a major role regardless of medium supplement. In general, less browning of tissue and more normal cotyledon growth occurs in complete darkness; however, greater proliferation is observed in some cultures when an 18/6 hour photoperiod is provided.\n\nEmbryo germination and plant development is best accomplished on vermiculite saturated with Beasley-Ting (BT) medium supplemented with 500 mg/1 casein hydrolysate. Regenerated plants are conditioned in either a one to one mix of peat and sand or vermiculite by placing glass beakers over new plants and gradually increasing the size of the beakers from 10 ml to 150 ml as the plants grow.
28.3 dB Gain Pr-Doped Fluoride Fiber Amplifier Module Pumped by 1.017 µm InGaAs-LDs (1993)

The advent of the erbium-doped fiber amplifier has led to the construction of many attractive transmission systems in the 1.5 µm region such as ultra-long distance systems(1)(2), large capacity CATV systems(3)(4), and optical soliton transmission systems(5). On the other hand, the 1.3 µm transmission system, where most terrestrial fiber transmission systems installed around the world operate, makes great demands on the development of amplifiers operating at 1.3 µm region. To date, however, there have been no practical amplifiers developed yet.
A prototype of synthetic data generator (2011)

The massive and extensive use of information technologies has generated a significant increase in both data and applications to manipulate it. These applications should be tested with a enough and representative volume of data. Real-world data is generally not available for issues of confidentiality and privacy. Thus, it is necessary to have synthetic data generators for this purpose. In this paper a free software prototype (PSDG) designed by generating data is described. The prototype is capable of generating and loading synthetic data into an empty database. Shuffling, Nulling out, table-to-table synchronization techniques have been implemented in order to generate the data.
The bisphosphonate 2-PEBP inhibits cyclosporin A induced high-turnover osteopenia in the rat. (1990)

A bisphosphonate, 2-PEBP (2-(2-pyridinyl) ethylidene bisphosphonate), was administered to animals receiving cyclosporin A (CsA) in an attempt to modify the high-turnover osteopenia associated with CsA therapy. Four groups of female Sprague-Dawley rats were administered either vehicle or CsA (15 mg/kg per day) by gavage for 28 days, together with either normal saline solution or 2-PEBP (1.72 mg/kg per day) given by intraperitoneal injection on days 0,1, and 2. The groups thus comprised Group A, vehicle/normal saline; group B, vehicle/2-PEBP; group C, CsA/normal saline solution; group D, CsA/2-PEBP. All rats received tetracycline hydrochloride by intraperitoneal injection for histomorphometric labeling. Blood was sampled on days 0, 7, 14, 21, and 28 for ionized calcium, serum phosphate, parathyroid hormone (PTH), 1,25-dihydroxyvitamin D (1,25(OH)2D), blood urea nitrogen (BUN), creatinine, magnesium, and bone gla protein (BGP). Rats were killed on day 28 for tibial bone histomorphometry. All results were compared with group A. There were no significant differences in weight, ionized calcium, PTH, and serum phosphate between groups. Weight increased significantly by day 28 in all groups. Groups C and D revealed significantly higher levels of 1,25(OH)2D, BUN, and creatinine on days 14 and 28. Magnesium was significantly lower in groups C and D on days 14 and 28. BGP increased significantly in group C and decreased significantly in group B during the study. Tibial bone histomorphometry revealed high-turnover osteopenia in group C, significant improvement in both bone formation and resorption parameters in group D and hyperostosis in group B. Serum BGP reflected the histomorphometric indices of bone formation in each group.(ABSTRACT TRUNCATED AT 250 WORDS)
Seamless SIP multimedia session transfer on IPv6 network via device switching (2011)

Due to significant popularity of Location-based Services and Multimedia communication over mobile devices, there are many researches has been conducted to extend the features of location tracking and make it cost-effective to users. It becomes necessary for the users to have seamless communication with automated switching of software applications. This paper focuses on the performance of indoor location tracking system on IPv6 Network Island with multiple real time applications that has location assisted transfer for mobile users. RSSI (Received Signal Strength Indicator) mechanism has been used to locate the moving nodes. The developed location tracking server is having dynamic and centralized MySQL database management system. SIP (Session Initial Protocols) user agent has been used to deploy intercommunicating of multimedia data for instance; video and audio conference, text messaging among the moving nodes and user can transfer the seamlessly transfer the session to their nearest mobile node which will be determined by the Location Server. This paper is going to discuss about the seamless performance of SIP during the session transference. The developed project is cost-effective and precisely conducive for the industries or any indoor organization. The prototype of the project has been successfully developed and has been tested as well. The results show the seamless connectivity of the multimedia application during device switching.
Scintillation imaging: a technique to reduce coding noise in scanned coded aperture imagers (2004)

Coded aperture imagers provide the optimum means to generate an all-sky survey at gamma-ray energies from 10's of keV to a few MeV. Unfortunately, such imagers are plagued by systematic noise that limits their dynamic range. In par-ticular, spatial gradients in the background radiation across the detector and imperfectly coded signals from strong point sources in the field of view add artifacts to the images. Although theoretical signal-to-noise ratios of order 10<sup>4</sup> are possi-ble in perfectly coded images, real-world effects have limited performance of past imagers to significantly less than that. One technique to help remove these aberrations is the use of sequential exposures with a mask and it's inverse. However, for large instruments this is an impractical solution. In addition, it does not apply for scenes with rapidly varying sources. In a scanning instrument, one solution to this problem is to interleave the mask and anti-mask patterns in a sin-gle aperture in the direction of scan. A true source will oscillate between positive and negative images (i.e. scintillate) while spatially varying backgrounds are significantly suppressed.
Toward<i>in vivo</i>diagnosis of skin cancer using multimode imaging dermoscopy: (II) molecular mapping of highly pigmented lesions (2014)

We have developed a multimode imaging dermoscope that combines polarization and hyperspectral imaging with a computationally rapid analytical model. This approach employs specific spectral ranges of visible and near infrared wavelengths for mapping the distribution of specific skin bio-molecules. This corrects for the melanin-hemoglobin misestimation common to other systems, without resorting to complex and computationally intensive tissue optical models that are prone to inaccuracies due to over-modeling. Various human skin measurements including a melanocytic nevus, and venous occlusion conditions were investigated and compared with other ratiometric spectral imaging approaches. Access to the broad range of hyperspectral data in the visible and near-infrared range allows our algorithm to flexibly use different wavelength ranges for chromophore estimation while minimizing melanin-hemoglobin optical signature cross-talk.
Versioned File Backup and Synchronization for Storage Clouds (2013)

Cloud storage has become widely used for data backup and archiving. The current archiving systems typically support a specific cloud service and this vendor lock-in problem can cause a challenge in data migration and even data loss when a cloud service provider ceases to exist. We propose a system called Rosy Cloud for automatic backup and synchronization of client data on different clouds. Rosy Cloud uses a thin interface of storage cloud through HTTP requests, keeps all encrypted file versions on the cloud, and allows different devices to asynchronously synchronize with the cloud. Conflicts due to concurrent writes are detected and resolved using a DAG model. Rosy Cloud also supports secure file sharing among different users. We have implemented the Rosy Cloud prototype with three popular storage clouds. Experiments show that Rosy Cloud is effective for both backup and synchronization with low monetary cost.
Multiple‐Functional Capsule Catalysts: A Tailor‐Made Confined Reaction Environment for the Direct Synthesis of Middle Isoparaffins from Syngas (2006)

A capsule catalyst for isoparaffin synthesis based on Fischer-Tropsch reaction was designed by coating a H-ZSM-5 membrane onto the surface of the pre-shaped Co/SiO(2) pellet. Morphological and chemical analysis showed that the capsule catalyst had a core-shell structure. A compact, integral shell of H-ZSM-5 crystallized firmly on the Co/SiO(2) substrate without crack. Syngas passed through the zeolite membrane to reach the Co/SiO(2) catalyst to be converted, and all hydrocarbons formed with straight chain structure must enter the zeolite channels to undergo hydrocracking as well as isomerization in this tailor-made confined reaction environment. A narrow, anti-Anderson-Schultz-Flory law product distribution was observed on these capsule catalysts. Contrary to a mechanical mixture of H-ZSM-5 and Co/SiO(2), C(10+) hydrocarbons were suppressed completely on this novel capsule catalyst, and the selectivity of middle isoparaffins was considerably improved. The carbon number distribution of the products depended on the thickness of the zeolite membrane, and it was possible to selectively synthesize specified distillates, such as gasoline-range, or heavier hydrocarbons from syngas directly, by simply adjusting the thickness of the zeolite membrane of the capsule catalyst. This kind of capsule catalysts can be extended to various consecutive reaction systems as the shell and core components are independent catalysts for different reactions. At the same time, shape selectivity and space-confined effects can be expected for the reactant, intermediates and product of the sequential reactions.
A novel technique for modulation alignment monitoring in RZ-DPSK systems using off-center optical filtering (2005)

A novel high-speed polarization-independent off-center optical filtering technique for monitoring alignment status between pulse generator and data modulator in RZ-DPSK systems is proposed and demonstrated. A monitoring dynamic range of 3.35 dB is achieved experimentally.
Amplification of the int-2 gene in primary human breast tumors. (1988)

Proviral activation of the int-2 gene is a frequent occurrence in mammary carcinomas induced by mouse mammary tumor virus (MMTV). Here, we have examined the human homolog of int-2 in 110 primary breast cancer DNAs. The locus was amplified 2- to 15-fold in 18 of the tumor DNA samples. Amplification of int-2 has a highly significant association (P less than 2 X 10(-6] with tumors from patients who subsequently developed a local recurrence of the disease or a distal metastasis.
Mutator phenotypes in mammalian cell mutants with distinct biochemical defects and abnormal deoxyribonucleoside triphosphate pools. (1981)

Recent studies of in vitro DNA synthesis have shown that fidelity of replication is influenced by the relative concentrations of deoxyribonucleoside triphosphates (dNTPs). Several investigators have used reconstituted prokaryotic replication systems to copy defined natural templates and have shown that specific incorporation errors can be induced by an appropriate bias of the precursor pools. The recent demonstration of mutator phenotypes among mutant Chinese hamster ovary cell lines with altered intracellular dNTP pools has allowed extension of the in vitro observations to eukaryotic replication and repair mechanisms. We describe here three mutant murine T-lymphosarcoma cell lines with altered dNTP pools and increased rates of spontaneous mutation to dexamethasone resistance and 6-thioguanine resistance. Unlike previously described mammalian cells with mutator phenotypes, these three lines have demonstrable defects in known structural gene products. Two of these cell lines are heterozygous for mutations affecting the M1 subunit of ribonucleoside diphosphate reductase; the other mutant is deficient in deoxycytidylate deaminase. In each cell line these mutations result in deranged endogenous dNTP pools and increased rates of spontaneous mutation, which are shown to be characteristic of the cell line and independent of the two genetic markers examined. Furthermore, normalization of the dNTP pools of the deaminase-deficient cells suppresses its mutator phenotype. Thus, abnormal dNTP pools seem to cause enhanced mutagenesis in mammalian cells.
Acoustic Air Pump (1957)

An air circulating pump that works on the principle of acoustic wind is described. The pump will move up to 700 l/min of air when powered at 60 cps by a 4-in. loudspeaker. The speaker diaphragm is the only moving part and could be protected by inert material when it is desired to seal in and circulate corrosive gases. Alternating current pickup from the speaker is so small as to be negligible in most instances.
Over-segmentation of 3D medical image volumes based on monogenic cues (2014)

In this thesis a novel approach to compute a 3D over-segmentation (supervoxels) for radiological image data is presented. It allows to cope with the high levels of noise and low contrast encountered in clinical data such as Computed Tomography (CT), Optical Coherence Tomography (OCT) and Magnetic Resonance (MR) images. The method, MonoSLIC, employs the transformation of the image content to its monogenic signal as primal representation of the image. The phase of the monogenic signal is invariant to contrast and brightness and by selecting a kernel size matched to the estimated average size of the superpixels it highlights the locally most dominant image edge. Employing an agglomeration step similar to the one used in SLIC-superpixels yields superpixels/-voxels with high fidelity to local edge information while being of regular size and shape. The proposed approach is compared to state of the art over-segmentation methods on the real-world images of the 2D Berkley Segmentation Dataset (BSD) converted to gray-scale, as well as on challenging 3D CT and MR volumes of the VISCERAL dataset. It yields a highly regular, robust, homogeneous and edge-preserving over-segmentation of the image/volume while being the fastest approach. For 3D volumes the method is 3 times faster than the state of the art. Due to its invariance to contrast and brightness it yields 11% higher recall rate when dealing with MR and CT volumes. There is also no parameter that needs to be tuned, increasing the usability of the method.
An object-oriented simulation-assignment model with consideration of mixed traffic flows for its applications (2006)

This paper aims at developing an integrated dynamic simulation-assignment model, DynaTAIWAN, for advanced traffic management systems as well as advanced traveller information systems. The model is composed of two layers, namely simulation-layer and real-time control layer. One of the key features of DynaTAIWAN is its ability to model multiple vehicle classes, especially motorcycles. Numerical experiments are conducted on two networks for illustrating possible capabilities of DynaTAIWAN
Development of HPMC and Eudragit S100 blended microparticles containing sodium pantoprazole. (2007)

Pantoprazole is used in the treatment of acid related disorders and Helicobacter pylori infections. It is activated inside gastric parietal cells binding irreversibly to the H+/K(+)-ATPase. In this way, pantoprazole must be absorbed intact in gastro-intestinal tract, indicating that enteric delivery systems are required. The purpose of this study was to prepare pantoprazole-loaded microparticles by spray-drying using a blend of Eudragit S100 and HPMC, which can provide gastro-resistance and controlled release. Microparticles presented acceptable drug loading (120.4 mgg(-1)), encapsulation efficiency (92.3%), surface area (49.0 m2g(-1)), and particle size (11.3 microm). DSC analyses showed that the drug is molecularly dispersed in the microparticles, and in vivo anti-ulcer evaluation demonstrated that microparticles were effective in protecting stomach against ulceration. Microparticles were successfully tabletted using magnesium stearate. In vitro gastro-resistance study showed that microparticles stabilized pantoprazole in 62.0% and tablets in 97.5% and provided a controlled release of the drug.
Mouse Oocytes Transcribe Injected <i>Xenopus</i> 5 <i>S</i> RNA Gene (1981)

Transcripts produced after injection of the Xenopus 5S RNA gene into oocyte germinal vesicles of mice migrate electrophoretically with the 5S RNA marker, an indication that the gene is transcribed and processed with considerable accuracy. Approximately two 5S RNA molecules are transcribed per gene per hour. This system may be useful in studying DNA processing and gene regulation by the mammalian ovum and might be modified to allow permanent incorporation of specific genes into mice.
Improved substrate selection for lateral field TSM sensors (2009)

In recent years there have been several motivations away from thickness field excitation and toward lateral field excitation for thickness shear mode (TSM) fluid phase sensors. Lateral field excitation offers an unmetallized sensor surface for electrical interactions while still providing for hermetic packaging of the driven electrodes. Historical substrate selections have supported both thickness field and lateral field excitation, incurring a hybrid operating mode and a significant issue with spurious signals. This effect is not conducive to a commercially-viable, mass-producible sensor. The objectives of this paper are to present a ground-up analysis of the ideal symmetry properties for lateral field excitation and to recommend classes of materials and proper orientations through which to obtain low-spurious lateral field excitation.
