Intra- versus intergranular low-field magnetoresistance of Sr2FeMoO6 thin films (1999)

Thin films of (001)-oriented Sr2FeMoO6 have been epitaxially deposited on LaAlO3 and SrTiO3 (001) substrates. Comparison of their transport and magnetic properties with those of polycrystalline ceramic samples shows a metallic versus semiconductor temperature dependence and a saturation magnetization Ms at 10 K of 3.2 μB/f.u. in the film as against 3.0 for a tetragonal polycrystalline sample. However, the Curie temperature TC≈389 K is reduced from 415 K found for the tetragonal ceramic, which lowers Ms at 300 K in the thin films to 2.0 μB/f.u. compared to 2.2 μB/f.u. in the ceramics. A Wheatstone bridge arrangement straddling a bicrystal boundary has been used to verify that spin-dependent electron transfer through a grain boundary is responsible for the low-field magnetoresistance found in polycrystalline samples below TC.

Complex Coronary Angioplasty: A Technique for Dilatation of Bifurcation Stenoses (1985)

Bifurcation stenoses have been recognized to be at "high risk" for acute closure during percutaneous transluminal coronary angioplasty. Use of the traditional single balloon technique in such situations often results in acute closure or worsening of the stenosis in the other branch. A technique utilizing simultaneous inflation of two balloons, ("kissing balloon" technique) has been utilized to avoid this complication. A double balloon technique has been developed using sequential inflations rather than simultaneous inflations to preserve the integrity of both branches while avoiding the arterial trauma produced by inflating two balloons in a small artery simultaneously. Twelve of 13 bifurcation stenoses were successfully treated with this sequential inflation double balloon technique. (Primary success rate = 92%).
Interest of Tumor-Specific CD4 T Helper 1 Cells for Therapeutic Anticancer Vaccine (2015)

Nowadays, immunotherapy represents one promising approach for cancer treatment. Recently, spectacular results of cancer immunotherapy clinical trials have confirmed the crucial role of immune system in cancer regression. Therapeutic cancer vaccine represents one widely used immunotherapy strategy to stimulate tumor specific T cell responses but clinical impact remains disappointing in targeting CD8 T cells. Although CD8 T cells have been initially considered to be the main protagonists, it is now clear that CD4 T cells also play a critical role in antitumor response. In this article, we discuss the role of tumor antigen-specific CD4 T cell responses and how we can target these cells to improve cancer vaccines.
Metabolic Signatures in Coronary Artery Disease: Results from the BioHEART-CT Study (2021)

Despite effective prevention programs targeting cardiovascular risk factors, coronary artery disease (CAD) remains the leading cause of death. Novel biomarkers are needed for improved risk stratification and primary prevention. To assess for independent associations between plasma metabolites and specific CAD plaque phenotypes we performed liquid chromatography mass-spectrometry on plasma from 1002 patients in the BioHEART-CT study. Four metabolites were examined as candidate biomarkers. Dimethylguanidino valerate (DMGV) was associated with presence and amount of CAD (OR) 1.41 (95% Confidence Interval [CI] 1.12-1.79, <i>p</i> = 0.004), calcified plaque, and obstructive CAD (<i>p</i> < 0.05 for both). The association with amount of plaque remained after adjustment for traditional risk factors, ß-coefficient 0.17 (95% CI 0.02-0.32, <i>p</i> = 0.026). Glutamate was associated with the presence of non-calcified plaque, OR 1.48 (95% CI 1.09-2.01, <i>p</i> = 0.011). Phenylalanine was associated with amount of CAD, ß-coefficient 0.33 (95% CI 0.04-0.62, <i>p</i> = 0.025), amount of calcified plaque, (ß-coefficient 0.88, 95% CI 0.23-1.53, <i>p</i> = 0.008), and obstructive CAD, OR 1.84 (95% CI 1.01-3.31, <i>p</i> = 0.046). Trimethylamine N-oxide was negatively associated non-calcified plaque OR 0.72 (95% CI 0.53-0.97, <i>p</i> = 0.029) and the association remained when adjusted for traditional risk factors. In targeted metabolomic analyses including 53 known metabolites and controlling for a 5% false discovery rate, DMGV was strongly associated with the presence of calcified plaque, OR 1.59 (95% CI 1.26-2.01, <i>p</i> = 0.006), obstructive CAD, OR 2.33 (95% CI 1.59-3.43, <i>p</i> = 0.0009), and amount of CAD, ß-coefficient 0.3 (95% CI 0.14-0.45, <i>p</i> = 0.014). In multivariate analyses the lipid and nucleotide metabolic pathways were both associated with the presence of CAD, after adjustment for traditional risk factors. We report novel associations between CAD plaque phenotypes and four metabolites previously associated with CAD. We also identified two metabolic pathways strongly associated with CAD, independent of traditional risk factors. These pathways warrant further investigation at both a biomarker and mechanistic level.
Light Field Retargeting from Plenoptic Camera to Integral Display (2017)

Light fields captured by plenoptic cameras have limited parallax and mismatched resolution causing shallow depth perception when viewed through integral displays. Our lightweight retargeting technique synthesizes light fields of enhanced parallax and controllable depth for immersive displaying experience.
Expressing joy through hip-hop dance steps: Focus on new jack swing (2016)

This study aimed to differentiate hip-hop dance steps based on whether joy was expressed and explained their movement features using three-dimensional motion analysis. Ten male and female participants (26.9 ± 12.8 years old) were instructed to perform an 80-second hip-hop dance, and the step performed after 60 s (new jack swing) was analyzed. Discriminant analysis was conducted, and the differences in the motion feature values were calculated by establishing 34 variables related to time and space. Furthermore, correlations between major joint sites that contributed to differentiation and other variables were calculated. The results revealed the following three points: The discriminant analysis, which was used to predict whether there was emotion, correctly classified cases at a rate of 70% or higher in four stages, which were motion phases. When the differences in motion features by intensity were identified in Phase 2—the phase with the highest correct classification rate—significant differences were found in the mean of the height in the shoulders, the speed of the left acromion, the speed of the capitellum of the left elbow joint, the speed of the center of the left wrist joint, the speed of the lateral condyle of the left femur, the speed of the right acromion, the speed of the capitellum of the right elbow joint, and the flexion angle of the upper torso. Under Strong Emotion, the speed of the left elbow joint and the speed of the center of the left wrist joint had the highest correlation (r = 0.92). Based on these results, we can conclude that it is possible to express joy through hip-hop dance, and, in the case of new jack swing, emotional expression is related mainly to the speed of the upper limbs.

Optical Imaging of Ventricular Action Potentials in a Torso Tank: A New Platform for Non-Invasive Electrocardiographic Imaging Validation (2019)

<b>Background:</b> Non-invasive electrocardiographic imaging (ECGI) is a promising tool to provide high-resolution panoramic imaging of cardiac electrical activity noninvasively from body surface potential measurements. Current experimental methods for ECGI validation are limited to comparison with unipolar electrograms and the relatively low spatial resolution of cardiac mapping arrays. We aim to develop a novel experimental set up combining a human shaped torso tank with high-resolution optical mapping allowing the validation of ECGI reconstructions. <b>Methods:</b> Langendorff-perfused pig hearts (<i>n</i> = 3) were suspended in a human torso-shaped tank, with the left anterior descending artery (LAD) cannulated on a separate perfusion. Electrical signals were recorded from an 108-electrode epicardial sock and 128 electrodes embedded in the tank surface. Simultaneously, optical mapping of the heart was performed through the anterior surface of the tank. Recordings were made in sinus rhythm and ventricular pacing (<i>n</i> = 55), with activation and repolarization heterogeneities induced by perfusion of hot and cold solutions as well as Sotalol through the LAD. Fluoroscopy provided 3D cardiac and electrode geometries in the tank that were transformed to the 2D optical mapping window using an optimization algorithm. Epicardial unipolar electrograms were reconstructed from torso potentials using ECGI and validated using optical activation and repolarization maps. <b>Results:</b> The transformation and alignment of the 3D geometries onto the 2D optical mapping window was good with an average correlation of 0.87 ± 0.10 and error of 7.7 ± 3.1 ms with activation derived from the sock. The difference in repolarization times were more substantial (error = 17.4 ± 3.7 ms) although the sock and optical repolarization patterns themselves were very similar (correlation = 0.83 ± 0.13). Validation of ECGI reconstructions revealed ECGI accurately captures the pattern of activation (correlation = 0.79 ± 0.11) and identified regions of late and/or early repolarization during different perfusions through LAD. ECGI also correctly demonstrated gradients in both activation and repolarization, although in some cases these were under or over-estimated or shifted slightly in space. <b>Conclusion:</b> A novel experimental setup has been developed, combining a human-shaped torso tank with optical mapping, which can be effectively used in the validation of ECGI techniques; including the reconstruction of activation and repolarization patterns and gradients.
Activity of nine antimicrobial agents against Lancefield group C and group G streptococci (1982)

The activity of nine antimicrobial agents against 44 strains of group C and group G streptococci was studied using a microtiter broth dilution technique. Several antimicrobial agents, including third-generation cephalosporins, the newer semisynthetic penicillins, and erythromycin, exhibited good activity against the organisms. Occasional tolerance to various agents was observed. No cross-tolerance was observed in this study.
Surface plasmon waves in nanoelectronic circuits (2004)

Abstract Plasma dynamics in nanoscale metal‐dielectric structures is reviewed, and circuit models for potential plasma wave nanodevices and circuits are developed. Circuit representations for surface‐plasmon waveguides, nanoantennas, and for surface plasmon generators based on attenuated total reflection (ATR), are presented. In metal–insulator–metal (MIM) structures tunnelling also excites surface plasmon waves, and the equivalent circuit introduced in this paper helps the design of circuits exploiting surface plasmon waves. These nanoelectronic circuits might have an impact on the future of terahertz and infrared electronics. Copyright © 2004 John Wiley &amp; Sons, Ltd.
Wheelchair Modification for Hands-Free Motion for Dancers With Disabilities (2008)

Functional modifications to power and manual chairs are currently advancing in the areas of rehabilitation, sports and recreation and in the activities of daily living; however, these modification have yet to be directly applied in the field of performing arts. An assistive device was developed at the University of South Florida (USF) during collaboration between the Department of Mechanical Engineering and the School of Theatre and Dance. The project was initiated by Professor Merry Lynn Morris who identified a need for new conceptions of mobility; her work with dancers, with and without disabilities established the research framework in which choreographic vision could be supported with technological applications. Therefore, a device was designed to alleviate the constraints of current wheelchair designs which inhibit the user’s upper-body artistic movement range and capacity for interaction. The main purpose of the design was to create hands-free motion through the modification of a power wheelchair, which make it useful in the performing arts, but also as an assistive device for persons with disabilities. This device is in its first research phase of development as a prototype and is patent pending.
Effect of primary posterior continuous curvilinear capsulorhexis with and without posterior optic buttonholing on postoperative anterior chamber flare (2009)

Cataract surgery with combined primary PCCC-POBH led to significantly lower postoperative anterior chamber reaction than conventional in-the-bag implantation during a 4-week follow-up. The tight capsule-optic diaphragm effectively prevented the ophthalmic viscosurgical device captured behind the optic from entering the anterior chamber postoperatively.
Enhancing Grid Security Using Workflows, Trusted Computing and Virtualisation. (2009)

This paper highlights the need to meet both Grid user and resource provider security requirements, describing the rationale for securing Grid workflows: a set of tasks arranged into a logical order to process a Grid user’s dataset. An overview of a secure protocol using Trusted Computing technology is provided, which is further enhanced with platform virtualisation hardware and software. The proposed scheme allows the selection of trustworthy resource providers and gives confidentiality and integrity protection to the workflow, the Grid user’s processes and data. The scheme also detects any problems during workflow execution, collecting information that can be used for
PD1 Blockade of Tumor-primed CD4 T Cells Instigates Protective Immunity Against Tumor Rechallenge. (2021)

Abstract Blockade of immune checkpoint PD1 in cancer patients results in remarkable therapeutic benefits. Revealing mechanisms underlying this revolutionary therapy is critical to identifying biomarkers for predicting responses to this treatment and developing novel PD1 blockade combined therapeutic regimens for broader clinical efficacy. Rejuvenation of preexisting intratumoral ‘exhausted’ T cells and recruitment of peripheral antitumor T cells into tumors have been suggested to explain how PD1 blockade works, but mechanisms of action of anti-PD1 therapy remain to be fully delineated. In a clinically relevant mouse model of spontaneous metastatic breast cancer 4T1.2-Neu, we show that effective and durable anti-PD1 therapy depends on systemic immunity, including type 1 conventional dendritic cells (cDC1: CD8α+/CD103+DC), B cells, CD4 and CD8 T cells. Increased circulating and/or tumor-infiltrating IL12+CD103+DC and IL2+CD4/CD8 T cells are associated with the response to anti-PD1 therapy. PD1 blockade results in tumor-primed CD44+IL2+CD4T cells in the periphery regardless of cDC1. In the breast cancer model with adoptive cell transfer (ACT), PD1 blockade-driven CD44+CD4+T cells infiltrate into tumors and ignite protective immunity against new tumors in an IL2-dependent and tumor-specific manner. In a distinct ACT model using enforced IL2-expressing melanoma antigen specific TRP1-transgenic (Tg) CD4 T cells, IL2+TRP1-Tg CD4 T cells control the growth of PD1-resistant endogenous BP or B16 melanoma. These data suggest the prominent role of PD1 blockade on the effectiveness of tumor-primed CD4T cells in tumor-specific immunity.
Separate session key generation approach for network and application flows in LoRaWAN (2019)

LoRaWAN prides itself in having security specified and implemented from the start. LoRaWAN also boasts end-to-end security between the device and the application server using an application session key, which protects in confidentiality the applicative payload, shielding it away from the prying eyes of the operator. Control messages exchanged between the end-device and the network server are also authenticated, with a different key, the network session key. However, with the current LoRaWAN 1.0 specification, both session keys (network and application) are generated by the same network server and they are derived from the same master key. Therefore, even though there are two different derived keys, there is no real isolation between network and application flows. As a result, this does not achieve good separation between network security and application security. Besides, it makes it complex to define the liability chain in case of key compromise. Moreover, with LoRaWAN 1.0, an end-device can only be connected to one application server. This connection is established as the end-device joins the network and is fixed as long as the end-device is connected to the network. The device cannot later send data to another application server, unless it de-associates with the network and re-associates, which is cumbersome and costly in terms of control messages.

Chloride conductance of CFTR facilitates basal Cl−/HCO3−exchange in the villous epithelium of intact murine duodenum (2005)

Villi of the proximal duodenum are situated for direct exposure to gastric acid chyme. However, little is known about active bicarbonate secretion across villi that maintains the protective alkaline mucus barrier, a process that may be compromised in cystic fibrosis (CF), i.e., in the absence of a functional CF transmembrane conductance regulator (CFTR) anion channel. We investigated Cl(-)/HCO(3)(-) exchange activity across the apical membrane of epithelial cells located at the midregion of villi in intact duodenal mucosa from wild-type (WT) and CF mice using the pH-sensitive dye BCECF. Under basal conditions, the Cl(-)/HCO(3)(-) exchange rate was reduced by approximately 35% in CF compared with WT villous epithelium. Cl(-)/HCO(3)(-) exchange in WT and CF villi responded similarly to inhibitors of anion exchange, and membrane depolarization enhanced rates of Cl(-)(out)/HCO(3)(-)(in) exchange in both epithelia. In anion substitution studies, anion(in)/HCO(3)(-)(out) exchange rates were greater in WT epithelium using Cl(-) or NO(3)(-), but decreased to the level of the CF epithelium using the CFTR-impermeant anion, SO(4)(2-). Similarly, treatment of WT epithelium with the CFTR-selective blocker glybenclamide decreased the Cl(-)/HCO(3)(-) exchange rate to the level of CF epithelium. The mRNA expression of Slc26a3 (downregulated in adenoma) and Slc26a6 (putative anion exchanger-1) was similar between WT and CF duodena. From these studies of murine duodenum, we conclude 1) characteristics of Cl(-)/HCO(3)(-) exchange in the villous epithelium are most consistent with Slc26a6 activity, and 2) Cl(-) channel activity of CFTR facilitates apical membrane Cl(-)(in)/HCO(3)(-)(out) exchange by providing a Cl(-) "leak" under basal conditions.
Study of Hopping Transport in Long Oligothiophenes and Oligoselenophenes: Dependence of Reorganization Energy on Chain Length (2008)

Internal reorganization energies for self-exchange hole-transfer process were calculated at the B3LYP/6-31G(d) level of theory for a series of oligothiophenes and oligoselenophenes up to the 50-mers. This is the first study of reorganization energy in very long pi-conjugated systems. We observed a linear correlation between reorganization energy and the reciprocal chain length for these long pi-conjugated heterocyclic oligomers, which can be explained by the changes in bond length that occur between the neutral and cation radical species and by the charge distribution in the cation radicals. In contrast to the saturation behavior observed for the HOMO-LUMO gaps of long pi-conjugated heterocyclic oligomers, the reorganization energy does not show saturation behavior for any length of the oligomers in this study, even up to the 50-mers. Interestingly, the reorganization energy approaches zero for infinite numbers of oligomer units (at the B3LYP/6-31G(d) level of theory), that is, for polythiophene and polyselenophene. The absolute values of the reorganization energies of oligoselenophenes, and the changes that occur in those energies with chain length, are similar to those found for oligothiophenes.
[3H]4‐(Dimethylamino)‐N‐[4‐(4‐(2‐methoxyphenyl)piperazin‐ 1‐yl)butyl]benzamide, a selective radioligand for dopamine D3receptors. I. In vitro characterization (2009)

4-(Dimethylamino)-N-(4-(4-(2-methoxyphenyl)piperazin-1-yl)butyl)benzamide (WC-10), a N-phenyl piperazine analog, has been shown to have high affinity and selectivity for dopamine D(3) receptors versus dopamine D(2) receptors (Chu et al. [2005] Bioorg Med Chem 13:77-87). In this study, WC-10 was radiolabeled with tritium (specific activity = 80 Ci/mmol) and [(3)H]WC-10 binding to genetically cloned dopamine D(2L) and D(3) receptors was evaluated in vitro. [(3)H]WC-10 binds with a 66-fold higher affinity to human HEK D(3) than HEK D(2L) receptors, with a dissociation constant (K(d)) of 1.2 nM at HEK D(3) receptors. However, [(3)H]WC-10 binds to rat Sf9 rD(3) receptors with a K(d) of 3.9 nM, a value that is 3-fold lower than binding to human HEK D(3) receptors and 40-fold value higher than binding to rat Sf9 rD(2L) receptors. The K(d) values obtained from saturation binding experiments were consistent with the results determined from kinetic (k(on) and k(off)) studies. The pharmacologic profiles of a series of dopaminergic drugs for inhibiting the binding of [(3)H]WC-10 to D(3) receptors was in agreement with previously reported data. In vitro autoradiography studies of rat and monkey brains show that [(3)H]WC-10 labeled D(3) sites in the striatal region.
