The C‐terminal Bisphosphorylated proenkephalin‐A‐(209–237)‐peptide from Adrenal Medullary Chromaffin Granules Possesses Antibacterial Activity (1996)

The chromaffin granules have been shown to be an excellent model to study the processing of proenkephalin-A and chromogranins. Recently, we reported a study dealing with the processing of chromogranin B/secretogranin I and the occurrence of the C-terminal chromogranin B-derived peptide 614-626 which was shown to have antibacterial activity [Strub, J.M., Garcia-Sablone, P., Looning, K., Taupenot, L., Hubert, P., Van Dorsselaer, A., Aunis, D. & Metz-Boutigue, M.H. (1995) Eur. J. Biochem. 229, 356-368]. We also observed that this new antibacterial activity present in chromaffin granules was associated with other endogenous protein-derived fragments yet to be characterized. The present study reports the isolation and characterization of a peptide which possesses antibacterial activity and which corresponds to the C-terminal 209-237 sequence of proenkephalin-A. A detailed study using microsequencing and matrix-assisted-laser-desorption time-of-flight mass spectrometry (MALD-TOF MS) allowed us to correlate the antibacterial activity of this peptide named enkelytin (FAEPLPSEEEGESYSKEVPEMEKRYGGFM) with post-translational modifications. Endogenous bisphosphorylated proenkephalin-A-(209-237) was active on Micrococcus luteus and Bacillus megaterium killing bacteria in the 0.2 - 0.4 microM range but was inactive in similar conditions towards Escherichia coli. Enkelytin shares sequence and structural similarities with the antibacterial C-terminal domain of diazepam-binding inhibitor. According to this similarity, a prediction of secondary structure is proposed for enkelytin and discussed in relationship to its biological activity.
Transient responses of superconducting lead films measured with picosecond laser pulses (1981)

Picosecond laser pulses are used, for the first time, to excite superconducting Pb films out of equilibrium. Pb microbridges are used to measure the threshold power needed to drive the Pb film normal as a function of temperature. Pb tunnel junctions are used to measure the quasiparticle relaxation times at temperatures close to ${T}_{c}$ and at low reduced temperatures. The measured quasiparticle relaxation time for a 500-\AA{} Pb-$\mathrm{Pb}{\mathrm{O}}_{x}$-500-\AA{} Pb tunnel junction is 3.1 nsec for the sample in vacuum at temperatures near ${T}_{c}$, and 2.5 nsec for the sample in superfluid at low reduced temperatures. At temperatures near ${T}_{c}$, the quasiparticle relaxation time for Pb is shown to be identical to the phonon escape time instead of the effective quasiparticle recombination time. At low reduced temperatures, the quasiparticle relaxation, for the case of excess quasiparticle density being much larger than the thermal equilibrium value, is shown to be approximately exponential with a time constant equal to twice the phonon escape time. The phonon transmissivities for the Pb-quartz, Pb-superfluid He, and Pb-$\mathrm{Pb}{\mathrm{O}}_{x}$ interfaces are determined from these relaxation time measurements to be 0.16, 0.16, and 0.2, respectively.
Autoregressive model based algorithm for correcting motion and serially correlated errors in fNIRS (2013)

Systemic physiology and motion-induced artifacts represent two major sources of confounding noise in functional near infrared spectroscopy (fNIRS) imaging that can reduce the performance of analyses and inflate false positive rates (i.e., type I errors) of detecting evoked hemodynamic responses. In this work, we demonstrated a general algorithm for solving the general linear model (GLM) for both deconvolution (finite impulse response) and canonical regression models based on designing optimal pre-whitening filters using autoregressive models and employing iteratively reweighted least squares. We evaluated the performance of the new method by performing receiver operating characteristic (ROC) analyses using synthetic data, in which serial correlations, motion artifacts, and evoked responses were controlled via simulations, as well as using experimental data from children (3-5 years old) as a source baseline physiological noise and motion artifacts. The new method outperformed ordinary least squares (OLS) with no motion correction, wavelet based motion correction, or spline interpolation based motion correction in the presence of physiological and motion related noise. In the experimental data, false positive rates were as high as 37% when the estimated p-value was 0.05 for the OLS methods. The false positive rate was reduced to 5-9% with the proposed method. Overall, the method improves control of type I errors and increases performance when motion artifacts are present.
Improvement of chronic idiopathic urticaria with <scp>l</scp>‐thyroxine: a new TSH role in immune response? (2005)

The reason of AT is associated to CIU and others allergical and autoimmune diseases is poorly known. The exclusive hormonal therapy reduces the symptoms of CIU and inflammatory response in many chronic diseases associated to AT. We suggest a stimulatory effect of TSH able to produce considerable changes of the immune response and immune tolerance in patients with AT causing target organs damage. The causal mechanism involves immune, nervous and endocrine system, sharing a common set of hormones, cytokines and receptors, in a unique totally integrated loop (the neuro-immuno-endocrine axis).
An Overview of Surface Roughness Effects on Nucleate Boiling Heat Transfer~!2009-10-31~!2010-01-01~!2010-04-16~! (2010)

The paper aims at an overview of heating surface microstructure effects on nucleate boiling heat transfer. A comprehensive chronological literature survey is presented followed by an analysis of the results of an experimental investigation. Boiling data of refrigerants R-134a and R-123 on 19 mm diameter copper and brass tubes of average surface roughness varying from 0.07 m to 10.5 m have been gathered under the present investigation. Though most of the data confirm previous literature trends, according to which the heat transfer coefficient increases with surface roughness, very rough surfaces present a peculiar behavior with respect to that of the smoother surfaces (Ra<3.0 m). Heat transfer performance of very rough surfaces is superior to the smoother ones at low heat fluxes (q<20 kW/m 2 ). However, decay in their thermal performance is observed in the high heat fluxes range. An in depth analysis of the effect of roughness on the slope, "m" of the h vs q curves has been performed with a general conclusion being that "m" is affected not only by de pressure but also by the surface roughness. Finally, an analysis of the active cavities density is performed using some models from the literature in order to evaluate the effect of surface roughness in cavity activation. The obtained results are generally inconclusive. However, it has been determined that surface microstructure effects must not be neglected in future models.
TRANSMISSION ELECTRON MICROSCOPY OF SURFACE AND INTERFACIAL STEPS (1997)

Transmission electron microscopy is uniquely able to extend techniques for imaging free surface steps to the buried interface regime, without significant loss of detail. Two mechanisms for imaging surface and interfacial steps by transmission electron microscopy are described. They are thickness contrast and strain contrast. The former reveals the position and approximate height of steps, whereas the latter detects stress fields which are commonly associated with steps. The basis for each of these methods is elaborated, and preliminary results are shown for step images at Si/SiO 2 interfaces, where measurable stress fields have been directly detected for the first time.
Recombinant Dengue 2 Virus NS3 Helicase Protein Enhances Antibody and T-Cell Response of Purified Inactivated Vaccine (2016)

Dengue virus purified inactivated vaccines (PIV) are highly immunogenic and protective over the short term, but may be poor at inducing cell-mediated immune responses and long-term protection. The dengue nonstructural protein 3 (NS3) is considered the main target for T-cell responses during viral infection. The amino (N)-terminal protease and the carboxy (C)-terminal helicase domains of DENV-2 NS3 were expressed in E. coli and analyzed for their immune-potentiating capacity. Mice were immunized with DENV-2 PIV with and without recombinant NS3 protease or NS3 helicase proteins, and NS3 proteins alone on days 0, 14 and 28. The NS3 helicase but not the NS3 protease was effective in inducing T-cell responses quantified by IFN-γ ELISPOT. In addition, markedly increased total IgG antibody titer against virus antigen was seen in mice immunized with the PIV/NS3 helicase combination in the ELISA, as well as increased neutralizing antibody titer measured by the plaque reduction neutralization test. These results indicate the potential immunogenic properties of the NS3 helicase protein and its use in a dengue vaccine formulation.
Simpson's Paradox, Lord's Paradox, and Suppression Effects are the same phenomenon – the reversal paradox (2008)

This article discusses three statistical paradoxes that pervade epidemiological research: Simpson's paradox, Lord's paradox, and suppression. These paradoxes have important implications for the interpretation of evidence from observational studies. This article uses hypothetical scenarios to illustrate how the three paradoxes are different manifestations of one phenomenon--the reversal paradox--depending on whether the outcome and explanatory variables are categorical, continuous or a combination of both; this renders the issues and remedies for any one to be similar for all three. Although the three statistical paradoxes occur in different types of variables, they share the same characteristic: the association between two variables can be reversed, diminished, or enhanced when another variable is statistically controlled for. Understanding the concepts and theory behind these paradoxes provides insights into some controversial or contradictory research findings. These paradoxes show that prior knowledge and underlying causal theory play an important role in the statistical modelling of epidemiological data, where incorrect use of statistical models might produce consistent, replicable, yet erroneous results.

Metabolic patterns for L-glutamate-U-C14 in slices of tumors and other tissues. (1957)

Summary 1.Metabolic patterns for l-glutamate-U-C 14 have been studied in systems containing slices of tumors and other tissues. 2.In the tumor , 7 per cent of the isotope of glutamate utilized was incorporated into protein. This incorporation was 6 or more times greater than that in the other tissues studied. The addition of glucose increased the incorporation to 11 per cent of the total. This effect was observed only in the tumor. Addition of glucose induced a 57 per cent suppression of the distribution of isotope into C 14 O 2 in the tumor. 3.In the kidney , total C 14 O 2 production from glutamate was considerably greater than that of any other tissues studied, but the percentage of the isotope of glutamate utilized that was recovered in CO 2 (25 per cent) was similar to that noted in the tumor, heart, and brain. The metabolic pattern did not change following the addition of glucose. Only 0.7 per cent of the isotope of glutamate utilized was incorporated into protein. 4.In the liver , the major pathway for glutamate-U-C 14 was to metabolic products of glutamate recovered by anion exchange chromatography. The rate of incorporation of the isotope of glutamate into protein was similar to that of the kidney. 5.The metabolic patterns for the brain and heart were similar to that of the kidney. A negligible percentage of the total isotope utilized was found in protein in the heart. 6.Inhibition of oxidation by malonate, fluoroacetate, and anaerobiosis suppressed protein labeling. Incorporation of glutamate into tumor protein was observed under conditions of anaerobiosis in the presence of 0.150 m glucose. Smaller concentrations (0.006 m) of glucose reversed the inhibitory effects of malonate on protein labeling in the tumor. 7.Following the induction of the malonate block, significantly greater radioactivity was found in the succinate pool of liver and kidney than in that of the tumor. Addition of glucose suppressed both the labeling of succinate and C 14 O 2 production in tumor slices treated with malonate. 8.The present studies indicate that the Walker 256 tumor is more efficient than the nontumor tissues studied in the incorporation of the isotope of glutamate into protein. Glycolysis enhances the efficiency of incorporation of glutamate into protein and simultaneously suppresses glutamate oxidation in the tumor.
Andean Roots and Tubers: Ahipa, Arracacha, Maca and Yacon (1997)

At least 25 species of root and tuber crops from 16 genera and 15 families are native to South America. Apart from the 7 species of potato (Solanum spp.), there are nine lesser known species native to the Andes that are grown for their edible underground organs and are traditionally, but not exclusively, cultivated by indigenous people who use them for subsistence or as cash crops. This book is the first of two volumes to deal in depth with the biology and genetic resources of these Andean root and tuber crops, and, following an introduction, is divided into 4 multiauthor sections: (1) ahipa (Pachyrhizus ahipa) by M. Sorensen, W. J. Gruneberg and B. Orting; (2) arracacha (Arracacia xanthorrhiza) by M. Hermann; (3) maca (Lepidium meyenii) by C. F. Quiros and R. Aliaga Cardenas; and yacon (Smallanthus sonchifolius) by A. Grau and J. Rea. Each section follows the standard format for the series and reviews aspects of their taxonomy, botany, origin, ecology, properties, uses, conservation, evaluation of diversity and breeding. In addition, full accounts are given of crop production areas, agronomy, limitations, prospects and research needs. A single appendix lists research workers by country.

Perfluorooctanoic Acid Degradation Using UV–Persulfate Process: Modeling of the Degradation and Chlorate Formation (2015)

In this study, we investigated the destruction and by-product formation of perfluorooctanoic acid (PFOA) using ultraviolet light and persulfate (UV-PS). Additionally, we developed a first-principles kinetic model to simulate both PFOA destruction and by-product and chlorate (ClO3(-)) formation in ultrapure water (UW), surface water (SW), and wastewater (WW). PFOA degradation was significantly suppressed in the presence of chloride and carbonate species and did not occur until all the chloride was converted to ClO3(-) in UW and for low DOC concentrations in SW. The model was able to simulate the PS decay, pH changes, radical concentrations, and ClO3(-) formation for UW and SW. However, our model was unable to simulate PFOA degradation well in WW, possibly from PS activation by NOM, which in turn produced sulfate radicals.
Array mode analysis of two-dimension phased arrays of vertical cavity surface emitting lasers (1990)

The modal properties of two-dimensional phase-locked arrays of vertical cavity surface emitting (VCSE) lasers where the spatial coherency across the aperture comes from the evanescent coupling of the optical fields of the lasers were investigated. Typical two-dimensional arrays can be separated into three categories: the periodic array, the circular array and the centered polygonal array (or concentric circular array). It is shown that symmetry plays an important role in determining the array mode, and that the use of VCSE lasers gives a good longitudinal mode selection leading to dynamic single-mode operation. These results can be extended to a quantum box laser array to give better optical beam control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Evaluation of extracellular polymeric substances extracted from waste activated sludge as a renewable corrosion inhibitor (2019)

The potentiodynamic polarization results indicated that EPS acts as a mixed-type inhibitor which inhibits corrosion on both anode and cathode sites of metal surfaces. Based on the FTIR results, it was assumed that major chemical groups O-H, N-H, C-N, C=O, and C-H contributed to the inhibition by adsorbing on the metal surface, forming a biofilm that acts as a protective barrier to isolate the metal from its corrosive environment. Results show that WAS EPS corrosion inhibitors have inhibition performance comparable to commercial products, signifying their potential in commercialization. This corrosion inhibitor is renewable, biodegradable, non-toxic, and free from heavy metal, making it a superior green corrosion inhibitor candidate. Additionally, turning biomass into value-added product can be beneficial to the environment and, in this case, deriving new materials from WAS could also transform the economics of wastewater treatment operations.
Epicutaneous Staphylococcus aureus induces IL-36 to enhance IgE production and ensuing allergic disease (2021)

IgE induced by type 2 immune responses in atopic dermatitis is implicated in the progression of atopic dermatitis to other allergic diseases, including food allergies, allergic rhinitis, and asthma. However, the keratinocyte-derived signals that promote IgE and ensuing allergic diseases remain unclear. Herein, in a mouse model of atopic dermatitis-like skin inflammation induced by epicutaneous Staphylococcus aureus exposure, keratinocyte release of IL‑36α along with IL-4 triggered B cell IgE class-switching, plasma cell differentiation, and increased serum IgE levels-all of which were abrogated in IL-36R-deficient mice or anti-IL‑36R-blocking antibody-treated mice. Moreover, skin allergen sensitization during S. aureus epicutaneous exposure-induced IL-36 responses was required for the development of allergen-specific lung inflammation. In translating these findings, elevated IL‑36 cytokines in human atopic dermatitis skin and in IL‑36 receptor antagonist-deficiency patients coincided with increased serum IgE levels. Collectively, keratinocyte-initiated IL‑36 responses represent a key mechanism and potential therapeutic target against allergic diseases.
Model-Free Reinforcement Learning of Impedance Control in Stochastic Environments (2012)

For humans and robots, variable impedance control is an essential component for ensuring robust and safe physical interaction with the environment. Humans learn to adapt their impedance to specific tasks and environments; a capability which we continually develop and improve until we are well into our twenties. In this article, we reproduce functionally interesting aspects of learning impedance control in humans on a simulated robot platform. As demonstrated in numerous force field tasks, humans combine two strategies to adapt their impedance to perturbations, thereby minimizing position error and energy consumption: 1) if perturbations are unpredictable, subjects increase their impedance through cocontraction; and 2) if perturbations are predictable, subjects learn a feed-forward command to offset the perturbation. We show how a 7-DOF simulated robot demonstrates similar behavior with our model-free reinforcement learning algorithm PI <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , by applying deterministic and stochastic force fields to the robot's end-effector. We show the qualitative similarity between the robot and human movements. Our results provide a biologically plausible approach to learning appropriate impedances purely from experience, without requiring a model of either body or environment dynamics. Not requiring models also facilitates autonomous development for robots, as prespecified models cannot be provided for each environment a robot might encounter.
Asymmetric immobilization of antibodies on a piezo-resistive micro-cantilever surface (2016)

Surface modification by continuous graft copolymerization. IV. Photoinitiated graft copolymerization onto polypropylene fiber surface (1990)

Abstract Photochemically induced graft copolymerization (with UV light) of acrylamide (AM) and acrylic acid (AA) on polypropylene (PP) fiber surface by the presoaking method under nitrogen atmosphere in a continuous process has been developed. The results are measured by means of ESCA spectra. In grafting AM and AA, the relative intensity N 1s /C 1s and O 1s /C 1s of the fiber increase from 3–5 and 20% (background) to 8–13 and 23–39% in 9–10 s irradiation time, respectively. Titration results show that 1.75 3.58 mg/m 2 poly(acrylic acid) has been grafted on the surface of PP fiber at various monomer concentrations of the presoaking solution. Commercial additives, such as antioxidant and UV stabilizer, affect the grafting yield of the fiber. As solvent in the presoaking solution, acetone is better than MEK and MPK. Various monomer and initiator concentrations in the presoaking solution have been studied. In the process developed 0.5–0.8 M acrylamide or 1.5–2.0 M acrylic acid and 0.2 M benzophenone (BP) in the presoaking solution are approapriate.
An approach to the reliability optimization of software with redundancy (1991)

An approach to the optimization of software reliability is proposed. The emphasis is put on the software redundancy to achieve fault tolerance, i.e. the results of the optimization process are used to determine the optimal structure of the software to be developed. Two optimization models are formulated covering, respectively, modified recovery block scheme and multiversion programming approaches. Both cases are illustrated by simple examples. The models show that it is possible to formulate and solve some software related reliability optimization problems. They further show that the concept of redundancy to achieve fault tolerance (basic for the traditional theory of reliability) can be used in the field of software reliability optimization.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
