Evaluation of chemical and morphological changes in radicular dentin after different final surface treatments (2018)

The aim of this study was to evaluate the chemical and morphological effects of different lasers as a final surface treatment for endodontic therapy through energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) respectively. Twenty-five maxillary canines were selected and instrumented with K3 system. Roots were randomly distributed into five groups (n = 5) according to the surface treatment: GI (distilled water), GII (NaOCl + EDTA), GIII (NaOCl + EDTA + 980 nm diode laser), GIV (NaOCl + EDTA+ 1,064 nm Nd:YAG laser), and GV (NaOCl + EDTA+ 2,780 nm Er, Cr:YSGG laser). Lasers were applied for 20 s and samples were bisected, exposing the treated surface and then subjected to elements quantification by EDS and morphological evaluation by scanning electron microscope (SEM). EDS data were submitted to ANOVA-two way, and SEM scores were submitted to two-way Kruskal-Wallis and Dunn's tests. The EDS analysis showed no difference for the chemical elements and Ca/P ratio between groups (p > .05). Statistical analysis showed more intense results for GV and less intense results for GI (p < .05). The GIII showed an amorphous organic matrix surface, while GV provided greater removal of intertubular dentin forming craters, and GIV promoted dentin fusion. The EDS method used in this study was not able to verify any chemical changes in root canal dentin; Nd:YAG, Er, Cr:YSGG, and 980 nm diode laser were capable of modifying the dentin morphology, correlating characteristics features for each one, which are essential clinical knowledge to establish the correct indication for each case. RESEARCH HIGHLIGHTS: EDS was not able to verify any chemical changes in root canal dentin after 980 nm diode, Nd:YAG and Er;Cr:YSGG laser treatments Nd:YAG, Er, Cr:YSGG, and 980 nm diode laser modified dentin morphology, correlating characteristics features for each one.
Reactive polymer membranes containing cuprous complexes in olefin/paraffin separation (2000)

The reduction of Cu(BF4)2·xH2O in 1 wt% poly(vinyl pyrrolidone)–methanol solution with trimethyl phosphite produced a solution containing cuprous complexes; the membrane prepared from this solution showed a maximum selectivity of 10 for propylene over propane at room temperature.

Unexpected end‐groups of poly(acrylic acid) prepared by RAFT polymerization (2004)

Abstract Low‐molecular‐weight poly(acrylic acid) (PAA) was synthesized by reversible addition fragmentation chain transfer polymerization with a trithiocarbonate as chain‐transfer agent (CTA). With a combination of NMR spectroscopy and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry, the PAA end‐groups of the polymer were analyzed before and after neutralization by sodium hydroxide. The polymer prior to neutralization is made up of the expected trithiocarbonate chain‐ends and of the H‐terminated chains issued from a reaction of transfer to solvent. After neutralization, the trithiocarbonates are transformed into thiols, disulfides, thiolactones, and additional H‐terminated chains. By quantifying the different end‐groups, it was possible to demonstrate that fragmentation is the rate limiting step in the transfer reaction. © 2004 Wiley Periodicals, Inc.

Cytokine Networks and the Regulation of Uterine Function in Pregnancy and Parturition (2008)

Complex cytokine networks play an important role in a wide range of reproductive and pregnancy related processes. Here, we review the current knowledge concerning the impact of cytokines on uterine physiology and pathophysiology. Cytokines influence a range of uterine functions during the menstrual cycle, implantation, pregnancy and labour. The synergistic interactions between individual cytokines are intricate and dynamic, and modulated by pregnancy hormones. It is not surprising therefore, that perturbations to cytokine signalling are associated with adverse pregnancy outcomes, such as miscarriage, pre-eclampsia, preterm labour and foetal brain injury. Further insight into the complexity of cytokine networks will be required to develop novel therapeutic strategies for the treatment of cytokine imbalances in pregnancy.
Sub-nanosecond pulse-forming network on SiGe BiCMOS for UWB communications (2006)

A pulse-forming network (PFN) has been developed for ultra-wideband (UWB) communication systems. This PFN generates sub-nanosecond pulses at a pulse repetition frequency (PRF) of >500 MHz for high data-rate applications like wireless video streaming. To generate the pulses, the PFN performs two operations on an input data signal: it decreases the signal rise time, then it differentiates the signal. The differentiation circuit is a frequency-dependent negative-feedback system. The PFN is fabricated in SiGe BiCMOS with an active die size of less than 0.25 mm/sup 2/, and it requires 3.3-V 20-mA dc during operation. Measured performance is validated at 500-MHz PRF, achieving pulsewidth of 175 ps and pulse amplitude of 0.17 V. The PFN is also validated within a transmitter system that transmits Manchester coded pseudorandom bit sequence. Measured effective isotropic radiated power of the transmitter shows that the PFN output power is sufficient to meet the Federal Communications Commission's emission limits, thus eliminating the need of amplification before transmission.
Ultra-low on-resistance 60-100 V superjunction UMOSFETs fabricated by multiple ion-implantation (2004)

We propose new low-voltage UMOSFETs with superjunction (SJ) structures to achieve ultra-low on-resistance. The present SJ structure has been formed by multiple boron ion implantations with varied energies up to 2 MeV. This technique enabled us to obtain p-columns with flat sidewalls, which minimize the interference to the drift conduction. The SJ diodes have clearly indicated the breakdown voltage enhancement as expected from the SJ characteristics. Drastic on-resistance reduction was demonstrated for the SJ-UMOSFETs with a breakdown voltage of 78 V.
A Heterogeneous Bayesian Regression Model for Cross-sectional Data Involving a Single Observation per Response Unit (2012)

Abstract Multiple regression is frequently used across the various social sciences to analyze cross-sectional data. However, it can often times be challenging to justify the assumption of common regression coefficients across all respondents. This manuscript presents a heterogeneous Bayesian regression model that enables the estimation of individual-level-regression coefficients in cross-sectional data involving a single observation per response unit. A Gibbs sampling algorithm is developed to implement the proposed Bayesian methodology. A Monte Carlo simulation study is constructed to assess the performance of the proposed methodology across a number of experimental factors. We then apply the proposed method to analyze data collected from a consumer psychology study that examines the differential importance of price and quality in determining perceived value evaluations.
Detection and identification of bacteria intimately associated with fungi of the order<i>Sebacinales</i> (2008)

Because of their beneficial impact on plants, the highly diverse mycorrhizal fungi grouped in the order Sebacinales lay claim to high ecological and agricultural significance. Here, we describe for the first time associations of Sebacinoid members with bacteria. Using quantitative PCR, denaturating gradient gel electrophoresis and fluorescence in situ hybridization, we detected an intimate association between Piriformospora indica and Rhizobium radiobacter, an alpha-Proteobacterium. The stability of the association, vertical transmission of the bacteria during asexual fungal reproduction and fungal plant colonization was monitored using R. radiobacter-specific primers. Treatment of mycelium or fungal protoplasts with antibiotics highly efficient against the free bacteria failed to cure the fungus. Barley seedlings dip-inoculated with R. radiobacter showed growth promotion and systemic resistance to the powdery mildew fungus Blumeria graminis comparable to P. indica inoculation. By screening additional isolates of the Sebacina vermifera complex, three species-specific associations with bacteria from the genera Paenibacillus, Acinetobacter and Rhodococcus were found. These findings suggest that Sebacinales species regularly undergo complex interactions involving host plants and bacteria reminiscent of other ectomycorrhizal and endomycorrhizal associations.
Photocatalytic generation of hydrogen by core-shell WO3/BiVO4 nanorods with ultimate water splitting efficiency (2015)

Efficient photocatalytic water splitting requires effective generation, separation and transfer of photo-induced charge carriers that can hardly be achieved simultaneously in a single material. Here we show that the effectiveness of each process can be separately maximized in a nanostructured heterojunction with extremely thin absorber layer. We demonstrate this concept on WO3/BiVO4+CoPi core-shell nanostructured photoanode that achieves near theoretical water splitting efficiency. BiVO4 is characterized by a high recombination rate of photogenerated carriers that have much shorter diffusion length than the thickness required for sufficient light absorption. This issue can be resolved by the combination of BiVO4 with more conductive WO3 nanorods in a form of core-shell heterojunction, where the BiVO4 absorber layer is thinner than the carrier diffusion length while it's optical thickness is reestablished by light trapping in high aspect ratio nanostructures. Our photoanode demonstrates ultimate water splitting photocurrent of 6.72 mA cm(-2) under 1 sun illumination at 1.23 V(RHE) that corresponds to ~90% of the theoretically possible value for BiVO4. We also demonstrate a self-biased operation of the photoanode in tandem with a double-junction GaAs/InGaAsP photovoltaic cell with stable water splitting photocurrent of 6.56 mA cm(-2) that corresponds to the solar to hydrogen generation efficiency of 8.1%.

Development and Characterization of Electrochemical Devices Using Ultraviolet Laser Induced Carbonization of Polyimide Films (1997)

The Photonics Research Center has been investigating the ultraviolet (UV) laser carbonization of polyimide films to produce electrically conducting polymer films. In this research, broadband UV laser radiation (350 to 380 nm) from a continuous wave (cw) argon ion laser is used to write a conducting pattern on the surface of polyimide films. Two scanning mirrors under computer control allow line drawings produced in a computer aided design (CAD) program to be reproduced with high precision. The oxidation‐reduction of was selected as a system to examine the electron transfer rates of the carbonized surfaces. Using methods developed by Nicholson, cyclic voltammetry of a 10 mM solution of in 1 M KCl was used to determine the rate of electron transfer from fabricated carbonized Kapton electrodes. The rate of electron transfer of the Kapton electrode was much slower when compared to commercial platinum and glassy carbon (GC) electrodes under the same conditions.

Immunoglobulin E Reactivity of Recombinant Allergen Tyr p 13 from <i>Tyrophagus putrescentiae</i> Homologous to Fatty Acid Binding Protein (2005)

The storage mite, Tyrophagus putrescentiae, is one of the important causes of allergic disorders. Fifteen allergenic components were demonstrated in storage mite by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting, but only the group 2 allergen Tyr p 2 has been cloned and characterized. In this study, we attempted to identify and characterize new allergens from T. putrescentiae, which is a dominant species of storage mite in Korea. Expressed sequence tags were analyzed to identify possible storage mite allergens, and the cDNA sequence encoding a protein homologous to fatty acid binding protein, a mite group 13 allergen, was identified and named Tyr p 13. Its deduced amino acid sequence showed 61.1 to 85.3% identity with other mite group 13 allergens. The recombinant protein was expressed in Escherichia coli using a pET 28b vector system, and its allergenicity was investigated by enzyme-linked immunosorbent assay (ELISA). The recombinant allergen was detected in 5 of 78 (6.4%) T. putrescentiae-positive sera tested, and it inhibited 61.9% of immunoglobulin E binding to crude extract at an inhibitor concentration of 10 mug/ml by inhibition ELISA using serum from the patient who showed the strongest reaction by ELISA. In this study, a novel allergen was identified in T. putrescentiae. This allergen could be helpful for more-detailed characterizations of storage mite allergy.
Cutting Edge: All-<i>trans</i> Retinoic Acid Down-Regulates TLR2 Expression and Function (2005)

A major consequence of microbial infection is the tissue injury that results from the host inflammatory response. In acne, inflammation is due in part to the ability of Propionibacterium acnes to activate TLR2. Because all-trans retinoic acid (ATRA) decreases inflammation in acne, we investigated whether it regulates TLR2 expression and function. Treatment of primary human monocytes with ATRA led to the down-regulation of TLR2 as well as its coreceptor CD14, but not TLR1 or TLR4. The ability of a TLR2/1 ligand to trigger monocyte cytokine release was inhibited by pre- and cotreatment with ATRA; however, TLR4 activation was affected by cotreatment only. ATRA also down-regulated monocyte cytokine induction by P. acnes. These data indicate that ATRA exerts an anti-inflammatory effect on monocytes via two pathways, one specifically affecting TLR2/1 and CD14 expression and one independent of TLR expression. Agents that target TLR expression and function represent a novel strategy to treat inflammation in humans.
Iteratively Learning Embeddings and Rules for Knowledge Graph Reasoning (2019)

Reasoning is essential for the development of large knowledge graphs, especially for completion, which aims to infer new triples based on existing ones. Both rules and embeddings can be used for knowledge graph reasoning and they have their own advantages and difficulties. Rule-based reasoning is accurate and explainable but rule learning with searching over the graph always suffers from efficiency due to huge search space. Embedding-based reasoning is more scalable and efficient as the reasoning is conducted via computation between embeddings, but it has difficulty learning good representations for sparse entities because a good embedding relies heavily on data richness. Based on this observation, in this paper we explore how embedding and rule learning can be combined together and complement each other's difficulties with their advantages. We propose a novel framework IterE iteratively learning embeddings and rules, in which rules are learned from embeddings with proper pruning strategy and embeddings are learned from existing triples and new triples inferred by rules. Evaluations on embedding qualities of IterE show that rules help improve the quality of sparse entity embeddings and their link prediction results. We also evaluate the efficiency of rule learning and quality of rules from IterE compared with AMIE+, showing that IterE is capable of generating high quality rules more efficiently. Experiments show that iteratively learning embeddings and rules benefit each other during learning and prediction.
Cloning, Sequencing, and Transcriptional Analysis of the Coenzyme F420-dependent Methylene-5,6,7,8-tetrahydromethanopterin Dehydrogenase Gene from Methanobacterium thermoautotrophicum Strain Marburg and Functional Expression in Escherichia coli (1995)

Two methylenetetrahydromethanopterin dehydrogenases have been purified from Methanobacterium thermoautotrophicum strain Marburg: one (MTD) is coenzyme F420-dependent and oxygen-stable (Mukhopadhyay, B., and Daniels, L. (1989) Can. J. Microbiol. 35, 499-507), and the other (MTH) is coenzyme F420-independent (or hydrogenase-type) and oxygen-sensitive (Zirngibl, C., Hedderich, R., and Thauer, R. K. (1990) FEBS Lett. 261, 112-116). Based on the NH2-terminal sequence of MTD, a 36-mer oligonucleotide was designed and used to identify and clone a 6.1-kilobase pair EcoRI fragment of M. thermoautotrophicum DNA. Sequencing of this fragment revealed an 825-base pair (bp) MTD encoding gene (mtd), which was expressed in Escherichia coli yielding an enzyme that, like the native enzyme, was oxygen-stable, strictly dependent on coenzyme F420, thermostable, thermophilic, and exhibited maximum activity at an acidic pH. The amino acid sequence predicts that MTD is a hydrophobic and acidic protein with no identifiable homology to MTH (von Bunau, R., Zirngibl, C., Thauer, R. K., and Klein, A. (1991) Eur. J. Biochem. 202, 1205-1208), but comparisons with coenzyme F420 utilizing enzymes revealed a conserved region at the NH2 terminus of MTD that could correspond to the ability to interact with coenzyme F420. The mtd transcript was approximately 900 nucleotides long and initiated 8 bp upstream of the translation initiation codon and 22 bp downstream from an archaeal promoter sequence. The mtd coding sequence was followed by several poly(dT) sequences and an inverted repeat that could be transcription termination signals.
Nucleotide sequence variation in Pneumocystis carinii strains that infect humans (1993)

The nucleotide sequences of a portion of the large-subunit mitochondrial rRNA gene of Pneumocystis carinii derived from 12 patients were examined. Five sequences were found to be identical to the prototype sequence reported by Sinclair et al. (K. Sinclair, A. E. Wakefield, S. Banerji, and J. M. Hopkin, Mol. Biochem. Parasitol. 45:183-184, 1991). Six sequences differed from the prototype sequence at one to three positions. The remaining sequence was markedly different from the prototype sequence and appeared to be a hybrid of the human and rat P. carinii sequences. The results of this study indicate the existence of multiple P. carinii strains infecting humans and suggest that coinfections of animal and human P. carinii strains in the same host are possible.
