Paramesonia marina gen. nov., sp. nov., isolated from deep-sea water of the Indian Ocean (2020)

A taxonomic study was carried out of strain K7<sup>T</sup>, which was isolated from deep-sea water collected from the Indian Ocean. The bacterium was Gram-stain-negative, aerobic, oxidase-negative, catalase-positive, rod-shaped and non-motile. Growth was observed at salinities of 0.5-10 % (optimum, 3 %), at a pH range of pH 6.0-10.0 (optimum, pH 7.0) and at temperatures of 10-40 °C (optimum, 28 °C). Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain K7<sup>T</sup> belonged to the family <i>Flavobacteriaceae</i>, with the high sequence similarities to the genera <i>Mesonia</i> (92.2 %-94.4 %), <i>Salinimicrobium</i> (91.9 %-93.2 %), <i>Salegentibacter</i> (92.1 %-92.6 %), <i>Leeuwenhoekiella</i> (92.1 %-92.3 %), <i>Gramella</i> (91.9 %-92.1 %) and <i>Zunongwangia</i> (91.8 %-92.1 %). The principal fatty acids were iso-C<sub>15 : 0</sub> (28.4 %), iso-C<sub>15 : 1</sub>G (14.2 %), summed feature 9 (iso-C<sub>17 : 1</sub> <i> </i>ω<i>9c</i> and/or C<sub>16 : 0</sub> 10-methyl; 11.6 %), iso-C<sub>17 : 0</sub> 3-OH (10.0 %) and summed feature 3 (C<sub>16 : 1</sub> <i>ω</i>7<i>c</i> and/or C<sub>16 : 1</sub> <i>ω</i>6<i>c</i>; 9.6 %). The G+C content of the chromosomal DNA was 35.8 mol%. The respiratory quinone was determined to be MK-6 (100 %). Phosphatidylethanolamine, two unidentified aminolipids, two unidentified phospholipid and four unidentified lipids were detected. The combined genotypic and phenotypic data show that strain K7<sup>T</sup> represents a novel species of a novel genus, for which the name <i>Paramesonia marina</i> gen. nov., sp. nov. is proposed, with the type strain K7<sup>T</sup> (=MCCC 1A01093<sup>T</sup>=KCTC 52325<sup>T</sup>).
The Clicked Pyridyl‐Triazole Ligand: From Homogeneous to Robust, Recyclable Heterogeneous Mono‐ and Polymetallic Palladium Catalysts for Efficient Suzuki–Miyaura, Sonogashira, and Heck Reactions (2013)

Abstract Various mono‐ and polymetallic palladium complexes containing a 2‐pyridyl‐1,2,3‐triazole (pyta) ligand or a nonabranch‐derived (nonapyta) ligand have been synthesized by reaction of palladium acetate with these ligands according to a 1:1 metal‐ligand stoichiometry and used as catalysts for carbon‐carbon cross‐coupling including the Suzuki–Miyaura, Sonogashira and Heck reactions. The unsubstituted monopalladium and nonapalladium complexes were insoluble in all the reaction media, whereas tri‐ and tetranuclar palladium complexes were soluble, which allowed conducting catalysis under either homogeneous or heterogeneous conditions. The organopalladium complexes were characterized by standard analytical and spectroscopic methods and by thermogravimetry showing decomposition above 110 °C. Both types of catalysts showed excellent activity for these cross carbon‐carbon bond formations involving aryl halides including activated aryl chlorides or acyl chloride. Besides the comparison between homogeneous and heterogeneous catalysis, the key feature of these catalysts is their remarkable robustness that allowed recycling at least ten times in the example of the Heck reaction with excellent yields and without significant reduction of the conversion.
Effect of different regression algorithms on the estimating leaf parameters based on selected characteristic wavelengths by using the PROSPECT model (2019)

In this study, the characteristic wavelengths of leaf biochemical parameters (including carotenoid content, chlorophyll ${a} + { b}$a+b content, dry matter content, equivalent water thickness, and leaf structure parameter) were obtained through a sensitivity analysis based on a physical model. Then, performance of the selected characteristic wavelengths for monitoring leaf biochemical contents (LBC) was analyzed by using the following six popular regression algorithms: random forest, backpropagation neural network, support vector regression, radial basic function neural network, partial least-squares regression, and Gaussian process regression of different parameter values/kernel functions/training functions. In addition, the optimal parameters of each regression algorithm for estimating LBC were determined. Lastly, the effect of different regression algorithms on the accuracy of LBC estimation using four different data sets was also discussed. The results demonstrated that the selected 10 characteristic wavelengths combined with the Gaussian process regression model can be efficiently applied in estimating LBC.
Optical and electro-optical properties of submicrometer lithium niobate slab waveguides prepared by crystal ion slicing and wafer bonding (2004)

LiNbO 3 thin film crystals have been produced using crystal ion slicing and wafer bonding. Films with a thickness of 680nm are produced on a thin layer of SiO2, which is deposited on a substrate with electrodes. The crystalline and optical qualities of the fabricated thin films are investigated and are comparable to bulk LiNbO3 single crystals. The effect of thermal annealing is studied using Rutherford backscattering. The refractive indices and the electro-optical (EO) coefficient of the fabricated films are measured using prism coupling dark line spectroscopy and modified attenuated total reflection. The EO coefficient is equal to r33=31pm∕V at λ=633nm.

Integration and evaluation of a gradient-based needle navigation system for percutaneous MR-guided interventions (2020)

The purpose of the present study was to integrate an interactive gradient-based needle navigation system and to evaluate the feasibility and accuracy of the system for real-time MR guided needle puncture in a multi-ring phantom and in vivo in a porcine model. The gradient-based navigation system was implemented in a 1.5T MRI. An interactive multi-slice real-time sequence was modified to provide the excitation gradients used by two sets of three orthogonal pick-up coils integrated into a needle holder. Position and orientation of the needle holder were determined and the trajectory was superimposed on pre-acquired MR images. A gel phantom with embedded ring targets was used to evaluate accuracy using 3D distance from needle tip to target. Six punctures were performed in animals to evaluate feasibility, time, overall error (target to needle tip) and system error (needle tip to the guidance needle trajectory) in vivo. In the phantom experiments, the overall error was 6.2±2.9 mm (mean±SD) and 4.4±1.3 mm, respectively. In the porcine model, the setup time ranged from 176 to 204 seconds, the average needle insertion time was 96.3±40.5 seconds (min: 42 seconds; max: 154 seconds). The overall error and the system error was 8.8±7.8 mm (min: 0.8 mm; max: 20.0 mm) and 3.3±1.4 mm (min: 1.8 mm; max: 5.2 mm), respectively.

Method for In-Field Evaluation of the Stator Winding Connection of Three-Phase Induction Motors to Maximize Efficiency and Power Factor (2006)

The performance of the oversized three-phase induction motors can be improved, both in terms of efficiency and power factor, with the proper change of the stator winding connection, which can be delta or star, as a function of their load. A practical method is proposed to quickly and easily evaluate which stator winding connection is more appropriate for the actual motor load profile, in order to increase the motor efficiency and power factor. This new method is suitable for in-field evaluation, because it requires only the use of inexpensive equipment and has enough accuracy to allow a proper decision to be made. The automatic change of the stator winding connection, as a function of the motor line current, is also analyzed. When properly applied, these methods can lead to the improvement of the efficiency and power factor of permanently oversized motors, motors with a load variation between low load and near full load during their duty cycle, and/or motors driving high-inertia, low duty cycle loads. The proposed methods are particularly suitable to industrial plants where typically many electric motor systems are oversized and/or can have a wide load variation. In these conditions, the active and reactive electrical energy bill can be significantly reduced.
An optimized approach to compute hybridization displacement charge and a study of its effects on electrostatic potentials of some biologically important molecules (1996)

Electrostatic potential maps of certain biologically important molecules (guanine, adenine, cytosine, thymine, and two conformers of glycine) were studied employing a “hybridization displacement charge (HDC)” correction to Löwdin charge distributions and using the conventional Mulliken charge distributions of the molecules. In these calculations, the magnitude of each of the point charges was distributed in 3-dimension in a spherically symmetric manner. The method of computing HDC using MNDO wave functions was optimized by introducing two adjustable parameters. It has been clearly demonstrated that HDC-corrected Löwdin charge distributions of the molecules mentioned above are able to reproduce most of the important features of their ab initio MEP maps, while the conventional Mulliken charge distributions fail in many respects. Thus, HDC-corrected Löwdin charge distributions are shown to be quite reliable for the study of molecular electrostatic properties, particularly for molecules with more than one competing electrophilic site. © 1996 John Wiley & Sons, Inc.

In vitro differentiation of HT‐29 M6 mucus‐secreting colon cancer cells involves a trychostatin A and p27KIP1‐inducible transcriptional program of gene expression (2007)

Tumor cell dedifferentiation-such as the loss of cell-to-cell adhesion in epithelial tumors-is associated with tumor progression. To better understand the mechanisms that maintain carcinoma cells in a differentiated state, we have dissected in vitro differentiation pathways in the mucus-secretor HT-29 M6 colon cancer cell line, which spontaneously differentiates in postconfluent cultures. By lowering the extracellular calcium concentration to levels that prevent intercellular adhesion and epithelial polarization, our results reveal that differentiation is calcium-dependent and involves: (i) a process of cell cycle exit to G(0) and (ii) the induction of a transcriptional program of differentiation gene expression (i.e., mucins MUC1 and MUC5AC, and the apical membrane peptidase DPPIV). In calcium-deprived, non-differentiated postconfluent cultures, differentiation gene promoters are repressed by a trichostatin A (TSA)-sensitive mechanism, indicating that loss of gene expression by dedifferentiation is driven by histone deacetylases (HDAC). Since TSA treatment or extracellular calcium restoration allow gene promoter activation to similar levels, we suggest that induction of differentiation is one mechanism of HDAC inhibitor antitumor action. Moreover, transcriptional de-repression can also be induced in non-differentiating culture conditions by overexpressing the cyclin-dependent kinase inhibitor p27(KIP1), which is normally induced during spontaneous differentiation. Since p27(KIP1) downregulation in colon cancer is associated with poor prognosis independently of tumor cell division rates, we propose that p27 (KIP1) may prevent tumor progression by, at least in part, enhancing the expression of some differentiation genes. Therefore, the HT-29 M6 model allows the identification of some basic mechanisms of cancer cell differentiation control, so far revealing HDAC and p27(KIP1) as key regulatory factors of differentiation gene expression.
Privacy-Preserving Online Mirror Descent for Federated Learning with Single-Sided Trust (2021)

This paper discusses how clients in a federated learning system can collaborate with privacy guarantee in a fully decentralized setting without a central server. Most existing work includes a central server that aggregates the local updates from the clients and coordinates the training. Thus, the setting in this existing work is prone to communication and computational bottlenecks, especially when large number of clients are involved. Also, most existing federated learning algorithms do not cater for situations where the data distribution is time-varying such as in real-time traffic monitoring. To address these problems, this paper proposes a differentially-private online mirror descent algorithm. To provide additional privacy to the loss gradients of the clients, local differential privacy is introduced. Simulation results are based on a proposed differentially-private exponential gradient algorithm, which is a variant of differentially-private online mirror descent algorithm with entropic regularizer. The simulation shows that all the clients can converge to the global optimal vector over time. The regret bound of the proposed differentially-private exponential gradient algorithm is compared with the regret bounds of some state-of-the-art online federated learning algorithms found in the literature.
Vildagliptin ist Sitagliptin in der Senkung der Nüchternglukose überlegen: Ergebnisse einer randomisierten kontrollierten Cross-Over Studie (2013)

Fragestellung: Obwohl Vildagliptin und Sitagliptin beide zur Klasse der DPP-4 Inhibitoren gehören, weisen sie Unterschiede im Mechanismus der Enzymhemmung auf: Während Vildagliptin einen Substrat-Enzym-Inhibitor mit langer Enzymbindung darstellt, ist Sitagliptin ein kompetitiver Inhibitor mit einer Enzymhemmung von äußerst kurzer Dauer. In der vorliegenden Studie wurde untersucht, ob sich diese Unterschiede auch in klinisch relevanten Parametern wie der Senkung der Nüchternglukose (FPG) zeigen.
Biosurfactants: Forthcomings and Regulatory Affairs in Food-Based Industries (2023)

The terms discussed in this review-biosurfactants (BSs) and bioemulsifiers (BEs)-describe surface-active molecules of microbial origin which are popular chemical entities for many industries, including food. BSs are generally low-molecular-weight compounds with the ability to reduce surface tension noticeably, whereas BEs are high-molecular-weight molecules with efficient emulsifying abilities. Some other biomolecules, such as lecithin and egg yolk, are useful as natural BEs in food products. The high toxicity and severe ecological impact of many chemical-based surfactants have directed interest towards BSs/BEs. Interest in food surfactant formulations and consumer anticipation of "green label" additives over synthetic or chemical-based surfactants have been steadily increasing. BSs have an undeniable prospective for replacing chemical surfactants with vast significance to food formulations. However, the commercialization of BSs/BEs production has often been limited by several challenges, such as the optimization of fermentation parameters, high downstream costs, and low yields, which had an immense impact on their broader adoptions in different industries, including food. The foremost restriction regarding the access of BSs/BEs is not their lack of cost-effective industrial production methods, but a reluctance regarding their potential safety, as well as the probable microbial hazards that may be associated with them. Most research on BSs/BEs in food production has been restricted to demonstrations and lacks a comprehensive assessment of safety and risk analysis, which has limited their adoption for varied food-related applications. Furthermore, regulatory agencies require extensive exploration and analysis to secure endorsements for the inclusion of BSs/BEs as potential food additives. This review emphasizes the promising properties of BSs/BEs, trailed by an overview of their current use in food formulations, as well as risk and toxicity assessment. Finally, we assess their potential challenges and upcoming future in substituting chemical-based surfactants.
Pyruvate Carboxylase Affinity Labelling of the Magnesium Adenosine Triphosphate Binding Site (1976)

The 2' , 3'-dialdehyde derivative of ATP (oATP) was prepared by periodate oxidation and on the following criteria was considered to be an effective affinity label. The magnesium complex of this derivative (Mg-oATP2) was shown to ba linear competitive inhibitor with respect to MgATP2-in both the acetyl-CoA-dependent and -independent activities of the enzyme but was a non-competitive inhibitor with respect to bicarbonate, and an uncompetitive inhibitor with respect to pyruvate. Mg-oATP was covalently bound to pyruvate carboxylase by reduction using sodium borohydride with concurrent irreversible inactivation of the enzyme...
Determination of Order Parameters in Laterally Fluorosubstituted Terphenyls by19F-NMR, Optical and Dielectric Anisotropies (2011)

Abstract Orientational order parameter in five fluorinated nematogens have been investigated by means of optical, dielectric and 19F NMR techniques. Quantum mechanical calculations were also employed to derive molecular and nuclear properties necessary for the analysis of the spectroscopic quantities. The obtained data were compared and discussed taking into account the differences among the three methods. The values of the order parameter differ due to different anisotropic physical quantities measured and, consequently, the different axes frame in which the order parameters are defined. However, the temperature trends, expressed with the aid of the Haller-type relation, are very close within the broad range of the nematic phase.

Purification, characterization and immunochemical properties of a novel 60-kDa protein ofVibrio anguillarumstrains (1998)

Vibrio anguillarum strains expressed increased amounts of a novel 60-kDa protein when cells were grown at physiologically elevated temperatures. The relative amounts of the 60-kDa protein were unaltered by changes in osmolarity or ionic concentration of the growth medium in cells grown at optimal growth temperatures. The N-terminal amino acid sequence analysis of the V. anguillarum 60-kDa protein showed extensive (94-89%) sequence identity with the 60-kDa heat shock protein of Yersinia enterocolitica and with Serratia rubidaea GroEL protein. Monoclonal antibodies against the Y. enterocolitica chaperonin reacted with the 60-kDa protein from V. anguillarum strains, and with a temperature-induced protein of similar molecular mass in other Gram-negative pathogens of fish.
Pushing the Limits of an O-18 Water Target (2003)

A gridded‐niobium target was constructed for the improvement of routine [18F]‐fluorine production from 18O‐enriched water on a CTI RDS 112 cyclotron. Niobium was chosen for its inertness and excellent thermal properties. The target volume consists of a 400μL (active volume) niobium chamber mounted with a single entrance foil supported against an array of 3mm hexagonal holes with 0.25mm aluminum septa, machined by EDM. The target operates at high beam currents and elevated pressures and temperatures with significant reductions in maintenance intervals. Several diagnostic tools such as autoradiography, activation, and neutron logging optimize the performance and yield of the target. Entrance foils including Havar and Nb are used to assess the [18F] chemical compatibility, with FDG synthesis as the test reaction. The gridded, single‐foiled niobium target chamber appears to be an improvement compared to a standard double‐foiled helium cooled water target used with RDS cyclotrons.
Design and fabrication of artificial lateral line flow sensors (2002)

Design and fabrication processes for realizing individual lateral line sensor nodes are discussed in this paper, along with preliminary characterization results.
Regulation of Root Elongation under Phosphorus Stress Involves Changes in Ethylene Responsiveness (2003)

We characterized the growth of the primary root of Arabidopsis under phosphorus sufficiency (1 mM phosphate) and deficiency (1 microM phosphate), focusing on the role of ethylene. We quantified the spatial profile of relative elongation with a novel method based on image processing, as well as the production rates of cortical cells, trichoblasts, and atrichoblasts. Phosphorus deficiency moderately decreased the maximal rate of relative elongation, shortened the growth zone, and decreased the production rate of both epidermal cell types but not of cortical cells. Inhibiting ethylene production (with aminoethoxyvinyl-glycine) or action (with 1-methylcyclopropene) increased elongation in high phosphorus and decreased it in low phosphorus. That these effects were specific to ethylene was confirmed by negating the effect of inhibited ethylene production with simultaneous treatment with an ethylene precursor (1-aminocyclopropane-1-carboxylic acid). Under both phosphorus regimes, ethylene regulated the maximal rate of relative elongation rather than the size of the growth zone. In addition, inhibiting ethylene action in high versus low phosphorus elicited opposite responses for the position of root hair initiation and for the production rates of cortex cells and atrichoblasts. We conclude that the root system acclimates to phosphorus deficiency by changing the signal transduction pathway connecting ethylene levels to growth and division.
