Formation of α- and β-Cembratriene-Diols in Tobacco (Nicotiana tabacum L.) Is Regulated by Jasmonate-Signaling Components via Manipulating Multiple Cembranoid Synthetic Genes (2018)

Cembranoids are a group of natural diterpenoid compounds with pharmaceutical potentials, and the cembratriene-diols produced by <i>Nicotiana</i> (tobacco) species display activities in anti-nicotine addiction and neuron protection. Although the enzymes catalyzing cembratriene-diols' formation in tobacco have been investigated, the regulatory mechanism underlying this physiological process remains unknown. This study has investigated the roles of phytohormone jasmonic acid (JA) in regulating cembratriene-diol formation in <i>N. tabacum</i> cv. TN90 and found that JA and COI1, the receptor protein of the bioactive derivative of JA (i.e., JA-Ile), display critical roles in regulating cembratriene-diols' formation and the expression of cembranoid synthetic genes <i>CBTS</i>, <i>P450</i> and <i>NtLTP1</i>. Further studies showed that over-expressing either the gene encoding bHLH transcription factor <i>MYC2a</i> or that encoding MYB transcription factor <i>MYB305</i> could upregulate the cembranoid synthetic genes and enhance the cembranoid production in plants with dysfunction of COI1. Further studies suggest that COI1 and its downstream regulators MYC2a and MYB305 also modulate the trichome secretion, which is correlated with cembranoid formation. Taken together, this study has demonstrated a critical role of JA-signaling components in governing the cembratriene-diol formation and the transcription of cembratriene-diol synthetic genes in tobacco. Findings in this study are of great importance to reveal the molecular regulatory mechanism underlying cembranoid synthesis.
MicroRNAs in Gene Regulation: When the Smallest Governs It All (2006)

Encoded by the genome of most eukaryotes examined so far, microRNAs (miRNAs) are small approximately 21-nucleotide (nt) noncoding RNAs (ncRNAs) derived from a biosynthetic cascade involving sequential processing steps executed by the ribonucleases (RNases) III Drosha and Dicer. Following their recent identification, miRNAs have rapidly taken the center stage as key regulators of gene expression. In this review, we will summarize our current knowledge of the miRNA biosynthetic pathway and its protein components, as well as the processes it regulates via miRNAs, which are known to exert a variety of biological functions in eukaryotes. Although the relative importance of miRNAs remains to be fully appreciated, deregulated protein expression resulting from either dysfunctional miRNA biogenesis or abnormal miRNA-based gene regulation may represent a key etiologic factor in several, as yet unidentified, diseases. Hence is our need to better understand the complexity of the basic mechanisms underlying miRNA biogenesis and function.
Inflammation: A driving force speeds cancer metastasis (2009)

It has been increasingly recognized that tumor microenvironment plays an important role in carcinogenesis. Inflammatory component is present and contributes to tumor proliferation, angiogenesis, metastasis and resistance to hormonal and chemotherapy. This review highlights the role of inflammation in the tumor metastasis. We focus on the function of proinflammatory factors, particularly cytokines during tumor metastasis. Understanding of the mechanisms by which inflammation contributes to metastasis will lead to innovative approach for treating cancer. How tumor spread remains an enigma and has received great attention in recent years, as metastasis is the major cause of cancer mortality. The complex and highly selective metastatic cascade not only depends on the intrinsic properties of tumor cells but also the microenvironment that they derive from. An inflammatory milieu consisting of infiltrated immune cells and their secretory cytokines, chemokines and growth factors contribute significantly to the invasive and metastatic traits of cancer cells. Here, we review new insights into the molecular pathways that link inflammation in the tumor microenvironment to metastasis.
SONET bidirectional ring capacity analysis: a pragmatic view (2002)

This paper presents the results of a theoretical analysis of SONET bidirectional rings. It provides significant insight into ring planning by studying the impact of the number of nodes on a ring, realizable assignments, and ring interconnection. A new concept of realizable assignments is developed and studied. Realizable assignments provide a pragmatic method of determining the assignment capacity of the Bidirectional Line Switched Rings. The ring interconnection analysis studies the impact of inter-ring vs. intra-ring demand, drop and continue, and DS1 grooming at ring interconnect nodes on the economic prove-in of rings.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Beyond Colloidal Cesium Lead Halide Perovskite Nanocrystals: Analogous Metal Halides and Doping (2017)

Colloidal CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) are being explored extensively as an interesting variety of defect-tolerant materials, wherein high efficiencies of optical and optoelectronic processes can be achieved even in the presence of surface defects. This defect-tolerant nature arises mainly because of the unique electronic band structure of these perovskites. Consequently, synthesis and exploration of other metal halide {CsSnX3, Cs2SnX6, and (CH3)3Bi2X9} NCs with electronic band structure similar to that of CsPbX3 perovskite have begun with high promise. Another initiative to tailor the properties is the doping of metal ions (Mn2+, Zn2+, Cd2+, Sn2+, and Bi3+) into the lattice of CsPbX3 NCs. Furthermore, nanocomposites of CsPbX3–metal and CsPbX3–dielectric layer–metal have been attempted. Here we discuss the recent progress in the research of these colloidal metal halide NCs that are either analogous to CsPbX3 perovskites or derivatives of CsPbX3 perovskites.
Effects of Corona‐Discharge Induced Oxygen Ion Beams and Electric Fields on Silicon Oxidation Kinetics: I . Ion Beam Effects (1985)

At temperatures between 500° and 950°C, in an oxygen ambient, a flux of either negative or positive oxygen ions, generated via a point‐to‐plane corona discharge, is directed to the front side of a silicon wafer. Electrical contact to the wafer was made via the back side. Both ion beam polarities lead to oxidation enhancement, but with very different oxide thickness profiles, even though the ion beam current density profiles in the gas phase at the surface are almost identical. Wafer orientation, , current, temperature, and time dependences have been studied.
Magnetic properties of epitaxial NiFe/Cu/Co spin-valve structures on GaAs(001) (2000)

Cu(50 Å)/NiFe(60 Å)/Cu(60 Å)/Co(20 Å) epitaxial spin-valve structures were grown on GaAs(001) substrates by molecular-beam epitaxy at room temperature. In situ reflection high-energy electron diffraction measurements indicate the stabilization of the bcc-Co(001) phase on 1×1 unreconstructed GaAs(001) for thicknesses up to 20 Å and the epitaxial growth of the fcc-Cu(001) spacer layer and fcc-FeNi(001) top magnetic layer. Magneto-optical Kerr effect and Brillouin light-scattering measurements of the composite structure showed that a fourfold cubic anisotropy is present but a twofold anisotropy also occurs directed along the 〈110〉 axes. The easy cubic axes are directed along the 〈100〉 axes, which implies that the cubic anisotropy constant Kl for bcc-Co is positive. The magnetic anisotropy of the bcc-Co layer has a striking influence on the magnetoresistance characteristics which were found to be angular dependent. A simulation of this mixed anisotropy behavior yields quantitative agreement with the experimental results.
Optoelectronic Neural Networks Based On Holographically Interconnected Image Processors (1988)

We describe an optoelectronic resonator associative memory system which utilizes holographic interconnects. Image processing techniques are used to implement nonlinearities and feedback. We show using numerical models that both power law and sigmoidal nonlinearities improve the storage capacity. Our experimental results lead us to be optimistic that this hybrid optical/electronic approach can be extended to adaptive neural network models.
The Neuropathic Diabetic Foot Ulcer Microbiome Is Associated With Clinical Factors (2012)

Nonhealing diabetic foot ulcers (DFUs) are a common and costly complication of diabetes. Microbial burden, or "bioburden," is believed to underlie delayed healing, although little is known of those clinical factors that may influence microbial load, diversity, and/or pathogenicity. We profiled the microbiomes of neuropathic nonischemic DFUs without clinical evidence of infection in 52 individuals using high-throughput sequencing of the bacterial 16S ribosomal RNA gene. Comparatively, wound cultures, the standard diagnostic in the clinic, vastly underrepresent microbial load, microbial diversity, and the presence of potential pathogens. DFU microbiomes were heterogeneous, even in our tightly restricted study population, but partitioned into three clusters distinguished primarily by dominant bacteria and diversity. Ulcer depth was associated with ulcer cluster, positively correlated with abundance of anaerobic bacteria, and negatively correlated with abundance of Staphylococcus. Ulcer duration was positively correlated with bacterial diversity, species richness, and relative abundance of Proteobacteria, but was negatively correlated with relative abundance of Staphylococcus. Finally, poor glycemic control was associated with ulcer cluster, with poorest median glycemic control concentrating to Staphylococcus-rich and Streptococcus-rich ulcer clusters. Analyses of microbial community membership and structure may provide the most useful metrics in prospective studies to delineate problematic bioburden from benign colonization that can then be used to drive clinical treatment.
Target-oriented diversity stacking for virtual-source imaging and monitoring (2018)

Abstract Interferometric virtual-source (VS) redatuming crosscorrelates downgoing waves with the corresponding upgoing waves to convert records from surface-source gathers to virtual gathers at the buried receiver locations. It can be viewed as the cancellation of common parts of the raypaths from surface sources to different buried receivers. As part of this process, a stacking operator — a uniform or simple offset function — is applied to weight and sum the surface-source array to form the VS. The stacking operator should preserve sources associated with effective cancellations of common raypaths and suppress ineffectively cancelling sources. The VS records should show reduced effects of overburden complexity, therefore providing improved image quality as well as improved repeatability in time-lapse monitoring. However, complex near-surface effects such as intricate shallow structures and variable weathering layers can severely distort the raypaths. As a result, sources associated with ineffective-raypath cancellation can produce substantial artifacts, instead of being spatially suppressed by the conventional stacking operator. To address these issues, we propose a data-driven VS method with a diversity-stacking theme in which each individual source contribution is weighted by certain quality measures. Specifically, we predict the upgoing wavefields using the conventional VS response and use the quality of these predictions compared with the original upgoing wavefields to approximate the weight of each source for the diversity stacking. Compared with previous methods, the new VS approach provides improved image quality and repeatability based on a pilot field of 13 time-lapse surveys, which reduced a significant repeatability problem across a 17-month survey gap.
10 GHz bandwidth, 20 dB gain low-noise direct-coupled amplifier ICs using Au/WSiN GaAs MESFET (1990)

A low-noise direct-coupled amplifier IC with a bandwidth of 10GHZ was developed using a 0.4 μm gate-length Au/WSiN GaAs MESFET technology. The amplifier achieved a high gain of 20 dB and a minimum noise figure of 3.2 dB with a power consumption of 365 mW.
Ways of relating (2017)

Abstract Participants of ballet classes relate to each other in various ways. Four practices are scrutinized here in particular – molding, mirroring, spacing and presenting. Through these, balletic bodies are fabricated. In each of these contexts, the relevant activities are distributed across several participants, and human bodies take part as very different “participation units” such as collaborating muscles and hands or visually connected movement displays. Drawing on ethnographic data, I argue that in order to understand what goes on “between” bodies, one must explore the practice-specific and situational ways of relating and the specific according involvements of bodies as parts of material culture.

Simulation and rapid prototyping environment for underwater acoustic communications: reconfigurable modem (2005)

Acoustic communications and networking research depends heavily on validation of the proposed algorithms through experiments. These experiments are usually carried out by off-line processing of data recorded in real channels. In this paper, we present a new simulation and rapid prototyping environment called the reconfigurable modem (rModem). The rModem can model acoustic communication and networking systems, simulate the system behavior, and generate C code based on the system model that can be run on a DSP board for real-time experimental studies.
Immunosuppression and Resultant Viral Persistence by Specific Viral Targeting of Dendritic Cells (2000)

Among cells of the immune system, CD11c(+) and DEC-205(+) splenic dendritic cells primarily express the cellular receptor (alpha-dystroglycan [alpha-DG]) for lymphocytic choriomeningitis virus (LCMV). By selection, strains and variants of LCMV that bind alpha-DG with high affinity are associated with virus replication in the white pulp, show preferential replication in a majority of CD11c(+) and DEC-205(+) cells, cause immunosuppression, and establish a persistent infection. In contrast, viral strains and variants that bind with low affinity to alpha-DG are associated with viral replication in the red pulp, display minimal replication in CD11c(+) and DEC-205(+) cells, and generate a robust anti-LCMV cytotoxic T lymphocyte response that clears the virus infection. Differences in binding affinities can be mapped to a single amino acid change in the viral glycoprotein 1 ligand that binds to alpha-DG. These findings indicate that receptor-virus interaction on dendritic cells in vivo can be an essential step in the initiation of virus-induced immunosuppression and viral persistence.
Rate of Ripening of Initiated Bananas as Influenced by Oxygen and Ethylene1,2 (1969)

Abstract The ability of initiated bananas to ripen at rates close to those considered normal was found to be ethylene dependent in low oxygen concentrations. Fruit denied ethylene by low oxygen treatments, which reduced the fruit's ability to produce ethylene, ripened far slower than similarly treated fruit receiving exogenous ethylene. A sequence of ripening changes was proposed to account for the present knowledge of ripening.
A multiplex TaqMan qPCR assay for sensitive and rapid detection of phytoplasmas infecting Rubus species (2017)

Rubus stunt is an economically important disease in the production of raspberries, blackberries, and loganberries. A fast, sensitive, and reliable diagnosis of phytoplasmas, the causal agent of the disease, is of prime importance to stop its spread by vegetative propagation and by insect vectors. Therefore, multiplex qPCR assays using TaqMan probes with different kinds of fluorophores in one reaction were developed, allowing the detection of phytoplasmas in general as well as a more specific detection of phytoplasmas belonging to group 16SrV and host DNA (either plant or insect). This assay now provides a practical tool for the screening of motherplants and monitoring the presence and distribution of phytoplasmas in Rubus plants of different geographic origins, cultivars, and cultivation systems, as well as in putative insect vectors like leafhoppers.
Anomalous behaviour of a protein during SDS/PAGE corrected by chemical modification of carboxylic groups (1991)

The 29,000-Mr Actinomadura R39 beta-lactamase exhibited a remarkably low electrophoretic mobility on SDS/PAGE, yielding an Mr value almost twice that computed from the corresponding gene sequence. We showed that chemical modification of the carboxylic groups of glutamic acid and aspartic acid residues restored a normal electrophoretic mobility and that the anomalous behaviour of that protein on SDS/PAGE was due to its very large negative charge at neutral pH. We also compared the behaviour of the same enzyme on gel filtration in the presence of SDS with those of other class A beta-lactamases (Mr approx. 30,000). These experiments suggested that the very low electrophoretic mobility of the Actinomadura R39 beta-lactamase upon SDS/PAGE was more probably due to a low degree of SDS binding rather than to an unusual shape of the SDS-protein complex.
Cutaneous Allodynia in Transformed Migraine Patients (2007)

This study is the first to demonstrate allodynia in transformed migraine patients using a headache-free control population and supports the hypothesis that central sensitization plays a role in the evolution of transformed migraine.
Self-Assembling Cyclic <scp>d</scp>,<scp>l</scp>-α-Peptides as Modulators of Plasma HDL Function. A Supramolecular Approach toward Antiatherosclerotic Agents (2017)

There is great interest in developing new modes of therapy for atherosclerosis to treat coronary heart disease and stroke, particularly ones that involve modulation of high-density lipoproteins (HDLs). Here, we describe a new supramolecular chemotype for altering HDL morphology and function. Guided by rational design and SAR-driven peptide sequence enumerations, we have synthesized and determined the HDL remodeling activities of over 80 cyclic d,l-α-peptides. We have identified a few distinct sequence motifs that are effective <i>in vitro</i> in remodeling human and mouse plasma HDLs to increase the concentration of lipid-poor pre-beta HDLs, which are key initial acceptors of cholesterol in the reverse cholesterol transport (RCT) process, and concomitantly promote cholesterol efflux from macrophage cells. Functional assays with various control peptides, such as scrambled sequences, linear and enantiomeric cyclic peptide variants, and backbone-modified structures that limit peptide self-assembly, provide strong support for the supramolecular mode of action. Importantly, when the lead cyclic peptide c[wLwReQeR] was administered to mice (ip), it also promoted the formation of small, lipid-poor HDLs in vivo, displayed good plasma half-life (∼6 h), did not appear to have adverse side effects, and exerted potent anti-inflammatory effects in an acute in vivo inflammation assay. Given that previously reported HDL remodeling peptides have been based on α-helical apoA-I mimetic architectures, the present study, involving a new structural class, represents a promising step toward new potential therapeutics to combat atherosclerosis.
A prediction algorithm for haptic collaboration (2005)

The incorporation of haptic interfaces into collaborative virtual environments suffers from setbacks due to some inherent technical problem when the users are geographically distributed. The main causes of such discrepancies are network delay, lack of view of individual participants' activities (awareness), and haptic feedback. Although some strategies exist for dealing with those concerns, they don't adequately address realism, causality, and the sense of co-presence in collaborative virtual environments during closely-coupled haptic tasks. We propose an approach based on prediction to compensate the limitations and to visualize the whole scenario for the users in order to help them cope with existing drawbacks intuitively. We introduce a predictor which can determine lost-update messages to improvise the current state, guess the current network delay, and anticipate remote user's interaction strategy and virtual object's position/orientation based on the history.
