FESTERING FOOD: CHYTRIDIOMYCETE PATHOGEN REDUCES QUALITY OFDAPHNIAHOST AS A FOOD RESOURCE (2008)

When parasitic infections are severe or highly prevalent among prey, a significant component of the predator's diet may consist of parasitized hosts. However, despite the ubiquity of parasites in most food webs, comparisons of the nutritional quality of prey as a function of infection status are largely absent. We measured the nutritional consequences of chytridiomycete infections in Daphnia, which achieve high prevalence in lake ecosystems (>80%), and tested the hypothesis that Daphnia pulicaria infected with Polycaryum laeve are diminished in food quality relative to uninfected hosts. Compared with uninfected adults, infected individuals were smaller, contained less nitrogen and phosphorus, and were lower in several important fatty acids. Infected zooplankton had significantly shorter carapace lengths (8%) and lower mass (8-20%) than uninfected individuals. Parasitized animals contained significantly less phosphorus (16-18% less by dry mass) and nitrogen (4-6% less) than did healthy individuals. Infected individuals also contained 26-34% less saturated fatty acid and 31-42% less docosahexaenoic acid, an essential fatty acid that is typically low in cladocera, but critical to fish growth. Our results suggest that naturally occurring levels of chytrid infections in D. pulicaria populations reduce the quality of food available to secondary consumers, including planktivorous fishes, with potentially important effects for lake food webs.
NaOH-embedded three-dimensional porous boron nitride for efficient formaldehyde removal (2015)

Volatile organic compounds, especially formaldehyde (HCHO), are considered to be great sources of contaminants in indoor air. However, design and preparation of safe, cost-affordable, and reusable materials for HCHO removal at ambient conditions are still remarkably challenging. Here, we have developed a kind of novel NaOH-embedded three-dimensional porous boron nitride (NaOH-3D BN) with high and hierarchical porosities, which exhibit excellent removal performance for HCHO. The as-prepared 3D BN is used as an adsorbent and catalytic support, while the embedded NaOH is applied as a catalyst, giving rise to catalytic transformation from high-toxic HCHO to less-toxic formate and methoxy salts at room temperature. Furthermore, their effective reusability has been confirmed. Given the high removal and reusability performance as well as no use of precious materials, the NaOH-3D BN is envisaged to be valuable practically for indoor air purification.

Intra-arterial Beta Irradiation Prevents Neointimal Hyperplasia in a Hypercholesterolemic Rabbit Restenosis Model (1995)

Administration of intra-arterial beta irradiation with a 90Y source is technically feasible and compatible with an ordinary catheterization laboratory environment. A dose of 18 Gy effectively induces long-term inhibition of neointimal hyperplasia.
Site-Specific Labeling of Annexin V with F-18 for Apoptosis Imaging (2008)

Annexin V is useful in detecting apoptotic cells by binding to phosphatidylserine (PS) that is exposed on the outer surface of the cell membrane during apoptosis. In this study, we examined the labeling of annexin V-128, a mutated form of annexin V that has a single cysteine residue at the NH 2 terminus, with the thiol-selective reagent (18)F-labeling agent N-[4-[(4-[(18)F]fluorobenzylidene)aminooxy]butyl]maleimide ([(18)F]FBABM). We also examined the cell binding affinity of the (18)F-labeled annexin V-128 ([(18)F]FAN-128). [(18)F]FBABM was synthesized in two-step, one-pot method modified from literature procedure. (Toyokuni et al., Bioconjugate Chem. 2003, 14, 1253-1259). The average yield of [(18)F]FBABM was 23 +/- 4% (n = 4, decay-corrected) and the specific activity was approximately 6000 Ci/mmol. The total synthesis time was approximately 92 min. The critical improvement of this study was identifying and then developing a purification method to remove an impurity N-[4-[(4-dimethylaminobenzylidene)aminooxy]butyl]maleimide 4, whose presence dramatically decreased the yield of protein labeling. Conjugation of [(18)F]FBABM with the thiol-containing annexin V-128 gave [(18)F]FAN-128 in 37 +/- 9% yield (n = 4, decay corrected). Erythrocyte binding assay of [(18)F]FAN-128 showed that this modification of annexin V-128 did not compromise its membrane binding affinity. Thus, an in vivo investigation of [ (18)F]FAN-128 as an apoptosis imaging agent is warranted.
Ifosfamide Combinations in the Management of Lymphomas (1987)

SummaryThe stepwise development of ifosfamide-based combination regimens for lymphoma at the M. D. Anderson Hospital is summarized, starting with the single-agent phase-II study to the more recent MIME combination. A critical review of the ifosfamide papers presented at the ifosfamide symposium that dealt with the topic of lymphoma is summarized. The activity of ifosfamide-based regimens in Europe, USA and the Middle East suggests that this drug has an important role in the management of recurrent lymphoma and probably also in front-line therapy.
Study of Ki67 in odontogenic benign tumors (2023)

The aim of the present study was to investigate the Ki67 expression level and to measure the cell proliferation index (Ki67) in odontogenic benign tumors. This was an analytical cross-sectional study of odontogenic benign tumors. The sampling was non-probabilistic with an exhaustive recruitment including all biopsy or surgical excision specimen of odontogenic benign tumors. Ki67 immunohistochemistry was performed on histological sections of paraffin-fixed tissues of 3µ thickness with the Ki67 (MM1) monoclonal antibody. The studied variables were sociodemographic, clinical and histopathological. The data have been analysed with SPSS 20.0 software. : Ameloblastoma represented 50.9% of cases and cemento-osseous dysplasia 36.4%. Among the 28 ameloblastoma cases, the 15 (53.6%) were plexiform type, the 7 (25%) follicular type and the 6 (21.4%) unicystic type. The percentage of Ki67 labelled cells was less than 1% in 74.6% (n=41) of the tumors and was equal to 5% in 12.7% (n=7) of cases. A Ki67 law labelling was found in 87.3% (n=48) of tumours and a negative labelling in 12.7% (n=7) of cases. The odontogenic benign tumors had a weak Ki67 expression level and a low epithelial cell proliferation index. The Ki67 could not therefore be used as a predictive biomarker of tumor cell proliferation and the risk of recurrence in odontogenic benign tumors.
A Microprocessor Controlled OCD Starsensor (TOAST) (1989)

The TPD Off-Axis Star-Tracker (TOAST) aims at achieving a high accuracy of 1.5 arcsec in a 5.4°x8.1° field of view, combined with random pointing capability. This requires a guide-star limit of msilicon = 6.5, giving a 99% probability of finding at least two guide-stars in the field of view, thus permitting 3-axes attitude reconstitution. To enhance the usefulness of the sensor three modes of operation are provided, enabling respectively a survey of the starfield, guide-star acquisition and fine tracking. The sensor is based on a 576 x 385 elements CCD detector. A microprocessor electronics enables an efficient organization of the detector readout and starimage processing, rendering subelement starposition accuracies. The detector is cooled thermo-electrically. A functionally representative breadboard model was built and subjected to performance tests. Test results show that the measured performances are not far from the design goals.
Achieving Efficient Incorporation of π‐Electrons into Graphitic Carbon Nitride for Markedly Improved Hydrogen Generation (2018)

A rapid and highly efficient strategy for introducing C into g-C<sub>3</sub> N<sub>4</sub> involves copolymerizing π-electron-rich barbituric acid with melamine via a facile microwave-assisted heating, thereby eliminating the issues in conventional electric furnace heating, such as the severe volatilization, owing to the mismatch of the sublimation temperatures of barbituric acid and melamine. The g-C<sub>3</sub> N<sub>4</sub> catalyst after optimizing the C-doping content actively generates increased amounts of H<sub>2</sub> under visible light exposure with the highest H<sub>2</sub> generation rate of 25.0 μmol h<sup>-1</sup> , which is nearly 20 times above that using g-C<sub>3</sub> N<sub>4</sub> produced by conventional electric furnace heating of two identical monomers (1.3 μmol h<sup>-1</sup> ). As such, the microwave-assisted heating strategy may stand out as an extremely simple route to incorporating π-electrons into g-C<sub>3</sub> N<sub>4</sub> with markedly improved photocatalytic performance.
Analysis by GC-MS of Polycyclic Aromatic Hydrocarbons in a Cream Containing Coal Tar (2000)

Abstract Qualitative and quantitative PAHs composition of a cream containing coal tar (5%), used in cutaneous diseases treatment, was studied. Eleven PAHs were analysed in pure coal tar and in the cream by GC-MS, after ultrasonic extraction by pyridine. Ten PAHs were found in pure coal tar: naphthalene, biphenyl, acenaphthylene, fluorene, phenanthrene, anthracene, carbazole, fluoranthene, pyrene and benzo[a]pyrene. No traces of 2,3-benzofluorene were detected. Seven PAHs were identified in the cream: naphthalene, biphenyl, acenaphthylene, fluorene, phenanthrene, fluoranthene and pyrene. 2,3-benzofluorene was also absent in the cream. Anthracene, carbazole and benzo[a]pyrene (one of the most toxic) were present in coal tar and not detected in the cream. The seven PAHs found in the cream and in coal tar were quantified. Hydrocarbons concentrations were between 0.107 ± 0.0038 mg.g−1 (for biphenyl) and 0.734 ± 0.0438 mg.g−1 (for phenanthrene) in the cream and between 4.31 ± 0.23 mg.g−1 (for biphenyl) and 21.9 ± 0.57 mg.g−1 (for fluorene) in coal tar.
Qualitative microwave imaging of breast cancer with contrast agents (2019)

A microwave imaging (MWI) methodology for early diagnosis of breast cancer is presented. Instead of generating a tomographic image of the breast, the proposed technique aims to reconstruct a map of malignant tumours inside the breast by adopting an extended form of factorization method. The implementation of factorization method requires (i) two multi-static scattered field measurements around the breast, which correspond to two different states of the breast, and (ii) the inhomogeneous Green's function associated to the breast. For this purpose, the paper proposes the use of contrast agents, which selectively increase the dielectric properties of the malign tissues. Two multi-static field measurements are collected before and after the administration of contrast agents. Later, the inhomogeneous Green's function of the breast is estimated by back-propagating the scattered field measurements, which are taken before the contrast agent usage. The feasibility and efficiency of the proposed technique are demonstrated with numerical examples that are performed on a slice of the realistic breast phantoms, which are derived from real three dimensional magnetic resonance imaging (3D-MRI) measurements.
Phonetic speaker recognition using maximum-likelihood binary-decision tree models (2004)

Recent work in phonetic speaker recognition has shown that modeling phone sequences using n-grams is a viable and effective approach to speaker recognition, primarily aiming at capturing speaker-dependent pronunciation and also word usage. The paper describes a method involving binary-tree-structured statistical models for extending the phonetic context beyond that of standard n-grams (particularly bigrams) by exploiting statistical dependencies within a longer sequence window without exponentially increasing the model complexity, as is the case with n-grams. Two ways of dealing with data sparsity are also studied; namely, model adaptation and a recursive bottom-up smoothing of symbol distributions. Results obtained under a variety of experimental conditions using the NIST 2001 Speaker Recognition Extended Data Task indicate consistent improvements in equal-error rate performance as compared to standard bigram models. The described approach confirms the relevance of long phonetic context in phonetic speaker recognition and represents an intermediate stage between short phone context and word-level modeling without the need for any lexical knowledge, which suggests its language independence.
An In Vivo Study of the Prefrontal Cortex of Schizophrenic Patients at Different Stages of Illness via Phosphorus Magnetic Resonance Spectroscopy (1995)

Selectin catch–slip kinetics encode shear threshold adhesive behavior of rolling leukocytes (2008)

The selectin family of leukocyte adhesion receptors is principally recognized for mediating transient rolling interactions during the inflammatory response. Recent studies using ultrasensitive force probes to characterize the force-lifetime relationship between P- and L-selectin and their endogenous ligands have underscored the ability of increasing levels of force to initially extend the lifetime of these complexes before disrupting bond integrity. This so-called "catch-slip" transition has provided an appealing explanation for shear threshold phenomena in which increasing levels of shear stress stabilize leukocyte rolling under flow. We recently incorporated catch-slip kinetics into a mechanical model for cell adhesion and corroborated this hypothesis for neutrophils adhering via L-selectin. Here, using adhesive dynamics simulations, we demonstrate that biomembrane force probe measurements of various P- and L-selectin catch bonds faithfully predict differences in cell adhesion patterns that have been described extensively in vitro. Using phenomenological parameters to characterize the dominant features of molecular force spectra, we construct a generalized phase map that reveals that robust shear-threshold behavior is possible only when an applied force very efficiently stabilizes the bound receptor complex. This criteria explains why only a subset of selectin catch bonds exhibit a shear threshold and leads to a quantitative relationship that may be used to predict the magnitude of the shear threshold for families of catch-slip bonds directly from their force spectra. Collectively, our results extend the conceptual framework of adhesive dynamics as a means to translate complex single-molecule biophysics to macroscopic cell behavior.
The potential of targeting CYP11B (2016)

The availability of relevant and efficient screening systems for testing the effects of inhibitors of human CYP11B1 and CYP11B2, combined with experiences and success in synthesizing selective and efficient inhibitors of these isoenzymes, provides a realistic basis for a successful development of drugs using CYP11B1 and CYP11B2 as targets. The first clinical trials with the CYP11B2 inhibitor LCI699 demonstrated some side effects but showed inhibition of end-organ damage in animals, indicating that it might be a useful lead compound for future developments.
Preparation and properties of PLZT films from metallo-organic precursors (1989)

Abstract Crack free and dense PLZT (8/65/35) films 0.4 to 2.5 μm thick were prepared by spinning a solution of metallo-organic compounds of lead, lanthanium, zirconium and titanium onto sapphire substrates, and firing and annealing the films in air in the range 600 to 850°C. These firing temperatures resulted in films with grain sizes from 0.2 to 1.2 μm. Films fired at 650°C had a dielectric constant of 1800 and a dissipation factor of 2% at 1 kHz, and a spontaneous polarization of 5 μC/cm2. The linear and quadratic electro-optic coefficients were 30 × 10−12 m/V and 50 × 10−18 (m/V)2, respectively.
Prony Scenarios and Error Amplification in a Noisy Spike-Train Reconstruction (2018)

The paper is devoted to the characterization of the geometry of Prony curves arising from spike-train signals. We give a sufficient condition which guarantees the blowing up of the amplitudes of a Prony curve S in case where some of its nodes tend to collide. We also give sufficient conditions on S which guarantee a certain asymptotic behavior of its nodes near infinity.
Thick Pixelated CZT Detectors With Isolated Steering Grids (2005)

We explore the possibility to improve the performance of 0.5 cm thick Cadmium Zinc Telluride (CZT) detectors with the help of steering grids on the anode side of the detectors. Steering grids can improve the energy resolution of CZT detectors by enhancing the small pixel effect; furthermore, they can increase their detection efficiency by steering electrons to the anode pixels which otherwise would drift to the area between pixels. Previously, the benefit of steering grids had been compromised by additional noise associated with currents between the steering grids and the anode pixels. We use thin film deposition techniques to isolate the steering grid from the CZT substrate by a 150 nm thick layer of the isolator Aluminiumoxide. While the thin layer does not affect the beneficial effect of the steering grid on the weighting potentials and the electric field inside the detector, it suppresses the currents between the steering grid and the anode pixels. In this contribution, we present first results from a 2 x 2 x 0.5 cm CZT detector with 8 x 8 pixels that we tested before and after deposition of an isolated steering grid. The steering grid improves the 662 keV energy resolution of the detector by a factor of 1.3 (from about 2% to about 1.5%), while not reducing the detection efficiency. To gain further insights into the detector response in the region between pixels, we measured energy spectra with a collimated Cs137 source. The collimator measurements can be used to enhance our understanding of energy spectra measured under flood illumination of the detectors.

Electrochemical behavior of an interpenetrating polymer network hydrogel composed of poly(propylene glycol) and poly(acrylic acid) (2003)

Abstract An interpenetrating polymer network (IPN) hydrogel based on poly(propylene glycol) and poly(acrylic acid) was prepared by UV irradiation. The swelling behavior of the IPN hydrogel was studied by the immersion of the gel in aqueous NaCl solutions of various concentrations. The swelling ratio decreased with an increase in the NaCl concentration. The electrically sensitive behavior of the IPN hydrogel in electric fields was also investigated. The IPN hydrogel also showed a stepwise bending behavior that depended on the electric stimulus. The bending angle and bending speed of the IPN hydrogel were greatest in 0.6 wt % aqueous NaCl and increased with an increase in the applied voltage. © 2003 Wiley Periodicals, Inc.
