Enhancement of immunity against RSV-induced sarcomas by generation of hapten-reactive helper T lymphocytes. (1985)

Previous work from this laboratory has shown that preimmunization of syngeneic hosts with Rous sarcoma virus (RSV)-transformed cells elicits a strong immune response against the growth of transplantable RSV sarcomas, mediated by T lymphocytes expressing the surface phenotype of helper cell precursors (Prat, Di Renzo & Comoglio, 1983). This paper shows that anti-tumour immunity may be elicited in tumour-bearing animals by triggering an experimentally pre-amplified T-helper cell population at the site of tumour growth. Mice were treated with cyclophosphamide (which inactivates suppressor T cells) followed by skin sensitization to trinitrochlorobenzene (TNCB) according to a protocol that has been shown to induce an appreciably amplified generation of trinitrophenyl (TNP)-reactive helper T cells (Fujiwara et al., 1984). Five weeks after TNCB painting, mice were transplanted s.c. with a lethal dose of RSV-induced syngeneic sarcoma cells; the injection at the tumour site of TNCB induced the regression of the tumour in mice in which the TNP-helper cell population has been amplified, but not in controls, including those injected with a non-related hapten or sensitized to TNCB without inactivation of suppressors.
Targeting of stabilized plasmid lipid particles to hepatocytes<i>in vivo</i>by means of coupled lactoferrin (2007)

For non-viral gene delivery we prepared stabilized plasmid lipid particles (SPLPs), to which lactoferrin (LF) was coupled as a hepatocyte specific targeting ligand. LF-SPLPs and untargeted SPLPs labeled with [3H]cholesteryloleyl-ether were injected into rats. About 87% of the LF-SPLPs were eliminated from the blood within 5 min, while 80% of untargeted SPLPs were still circulating after 2 h. Fifty-two percent of the LF-SPLPs were taken up by hepatocytes, while non-parenchymal liver cells accounted for 16% of the uptake. Despite the efficient targeting of LF-SPLPs to hepatocytes and their capacity to transfect HepG2 and COS-7 cells in vitro, expression of a reporter gene was not detected in vivo. Overall, covalent coupling of LF to SPLPs leads to massive delivery in hepatocytes after systemic administration. However, these LF-SPLPs are not able to transfect these cells in vivo.
War and religion in ancient Mesopotama (1939)

Judging from repetitious appearances of her marital arms in the painted line-endings, the Psalter-Hours John Rylands Library Latin MS 117 probably belonged to Jeanne of Flanders (c.1272–1333), daughter of Count Robert III of Flanders and in 1288 second wife to Enguerrand IV of Coucy. Yet the line-endings also contain some 1,800 diminutive painted escutcheons, many of which refer to other members of the local nobility active during the 1280s. This study, based on an exhaustive survey of the total heraldic and codicological evidence, suggests that the majority of the extant Psalter predated the Hours and that the two parts were combined after the 1288 marriage. The ‘completed’ manuscript bears witness to major events that unfolded in and around the Coucy barony over the course of the decade. It suggests a complex relationship between Jeanne of Flanders and a lesser member of the local nobility, a certain Marien of Moÿ, who may have served as her attendant.
Supramolecular assembly of collagen triblock peptides (2003)

The relationship between primary sequence and collagen triple-helix formation is relatively well characterized, while higher levels of structural assembly from these sequences is poorly understood. To address this gap, a new collagen-like triblock peptide design was used to study the relationship between amino acid sequence and supramolecular assembly. Four collagen-like peptides with the sequence (Glu)(5)(Gly-Xaa-Hyp-Gly-Pro-Hyp)(6)(Glu)(5) and corresponding to Xaa = alanine, proline, serine, or valine, and an analogous peptide without the glutamic acid end blocks, were solubilized in water at high concentrations (20-150 mg/mL) and analyzed in optical polarizing microscopy and transmission electron microscopy. Some of the peptides self-assembled into supramolecular structures, the nature of which was determined by the core collagen-like sequence. The globular end blocks appeared necessary for these short triple-helix-forming peptides to spontaneously organize into supramolecular structures in solution and also provided enhanced thermal stability based on CD analysis. The results indicate a strong dependence of the peptide triblock assembly behavior on the identity of the guest residue Xaa; nematic order when Xaa was valine, no organization when Xaa was serine, and banded spherulites displaying a cholesteric-like twist when Xaa was proline or alanine. According to these results, the identity of the amino acid in position Xaa of the triplet Gly-Xaa-Yaa dramatically determined the type of supramolecular assembly formed by short triple helices based on collagen-triblock like sequences. Moreover, the structural organization observed for these collagen-triblock peptides was analogous to some assemblies observed for native collagen in vivo and in vitro. The amino acid sequence in the native collagen proteins may therefore be a direct determinant of the different supramolecular architectures found in connective tissues.
Unexpected Increased Mortality After Implementation of a Commercially Sold Computerized Physician Order Entry System (2005)

We have observed an unexpected increase in mortality coincident with CPOE implementation. Although CPOE technology holds great promise as a tool to reduce human error during health care delivery, our unanticipated finding suggests that when implementing CPOE systems, institutions should continue to evaluate mortality effects, in addition to medication error rates, for children who are dependent on time-sensitive therapies.
Dirhodium(<scp>ii</scp>) tetraacetate catalysed reactions of diazo thioamides: isolation and cycloaddition of anhydro-4-hydroxy-1,3-thiazolium hydroxides (thioisomünchnones), an approach to analogues of dehydrogliotoxin (2003)

Dirhodium(II) tetraacetate catalysed reaction of the indoline diazo thioamide 8 gives the thioisomünchnone 9, a stable characterisable solid. This masked thiocarbonyl ylide undergoes 1,3-dipolar cycloaddition with N-methylmaleimide and maleic anhydride to give the exo-cycloadducts 10 and 11, characterised by X-ray crystallography. The thioisomünchnone 18, derived from diazo thioamide 17, is an extremely stable crystalline mesoionic system which can be characterised by X-ray crystallography but fails to undergo intramolecular cycloaddition. The related thioisomünchnone 19 can be generated by reaction of indoline-2-thione 7 with bromoacetyl chloride in the presence of triethylamine, and undergoes cycloaddition to give adducts 20 and 21.

CDC20B is required for deuterosome-mediated centriole production in multiciliated cells (2017)

Abstract Multiciliated cells (MCCs) harbour dozens to hundreds of motile cilia, which beat in a synchronized and directional manner, thus generating hydrodynamic forces important in animal physiology. In vertebrates, MCC differentiation critically depends on the synthesis and release of numerous centrioles by specialized structures called deuterosomes. Little is known about the composition, organization and regulation of deuterosomes. Here, single-cell RNA sequencing reveals that human deuterosome-stage MCCs are characterized by the expression of many cell cycle-related genes. We further investigated the uncharacterized vertebrate-specific cell division cycle 20B ( CDC20B ) gene, the host gene of microRNA-449abc. We show that the CDC20B protein associates to deuterosomes and is required for the release of centrioles and the subsequent production of cilia in mouse and Xenopus MCCs. CDC20B interacts with PLK1, which has been shown to coordinate centriole disengagement with the protease Separase in mitotic cells. Strikingly, over-expression of Separase rescued centriole disengagement and cilia production in CDC20B-deficient MCCs. This work reveals the shaping of a new biological function, deuterosome-mediated centriole production in vertebrate MCCs, by adaptation of canonical and recently evolved cell cycle-related molecules.
Conversion of oxido-bridged dinuclear ruthenium complex to dicationic dinitrosyl ruthenium complex using proton and nitric oxide: Completion of NO reduction cycle (2010)

The hydroxido-bridged dinuclear ruthenium complex 4, which is supported by Tp ligands, has been prepared from protonation of the oxido-bridged dinuclear ruthenium complex 3. Additional protonation of 4, affording the aqua-bridged dinuclear ruthenium complex 5 in situ, and subsequent treatment with NO gave rise to the dicationic dinitrosyl complex 2. These indicate completion of the NO reduction cycle on the dinuclear ruthenium complex.
Being held hostage in The Netherlands: A study of long-term aftereffects (1989)

In the 1970s, The Netherlands were confronted with eight large-scale hijackings, in which a total of nearly 500 persons were held hostage. In 1985, the long-term aftereffects (up to 9 years) of these hostage takings were studied. Approximately one-third of the ex-hostages studied were found to suffer from negative effects resulting from the hostage-taking and mentioned symptoms related to DSM-III categories “post-traumatic stress disorder” and “generalized anxiety disorder,” and a variety of medical symptoms. Twelve percent of the ex-hostages were found to be still in need of aftercare and help, even though nearly all of them had had several contacts with professional health care workers in the period following the hijacking. A number of variables are described which are related to lower degrees of well-being and more negative aftereffects in ex-hostages, thereby suggesting the predictability of greater vulnerability in some hostages.
High-resolution two-dimensional dopant characterization using secondary ion mass spectrometry (2000)

A quantitative two-dimensional (2D) boron dopant profiling for submicron technology has been demonstrated using secondary ion mass spectrometry (SIMS). A novel test structure incorporating a moiré pattern has been developed to improve SIMS lateral resolution. This approach significantly simplifies 2D SIMS test chip manufacturing, data acquisition, and analysis. As a result, 2D dopant profiling with a lateral resolution limited by the photomask pixel size (10 nm) and sensitivity of 3×1017 cm−3 has been realized on commercial equipment. 2D dopant profiles are reproducible within 10 nm. The measured profiles were compared with 2D Monte-Carlo and calibrated TSUPREM4 simulations and showed good agreement.
Regulation of Epidermal Growth Factor Receptor Signaling in Human Cancer Cells by MicroRNA-7 (2008)

The epidermal growth factor receptor (EGFR) is frequently overexpressed in cancer and is an important therapeutic target. Aberrant expression and function of microRNAs have been associated with tumorigenesis. Bioinformatic predictions suggest that the human EGFR mRNA 3'-untranslated region contains three microRNA-7 (miR-7) target sites, which are not conserved across mammals. We found that miR-7 down-regulates EGFR mRNA and protein expression in cancer cell lines (lung, breast, and glioblastoma) via two of the three sites, inducing cell cycle arrest and cell death. Because miR-7 was shown to decrease EGFR mRNA expression, we used microarray analysis to identify additional mRNA targets of miR-7. These included Raf1 and multiple other genes involved in EGFR signaling and tumorigenesis. Furthermore, miR-7 attenuated activation of protein kinase B (Akt) and extracellular signal-regulated kinase 1/2, two critical effectors of EGFR signaling, in different cancer cell lines. These data establish an important role for miR-7 in controlling mRNA expression and indicate that miR-7 has the ability to coordinately regulate EGFR signaling in multiple human cancer cell types.
Epitaxial Growth of C<sub>60</sub> on Rubrene Single Crystals for a Highly Ordered Organic Donor/Acceptor Interface (2017)

The highly ordered epitaxial growth of C60 films on rubrene single crystals was demonstrated. The C60 crystals growth commensurate with rubrene (001) surface lattice was confirmed by reflection high energy electron diffraction and X-ray diffraction and grazing incident wide-angle X-ray scattering. Depending on growth conditions, several surface morphologies (rounded, hexagonal, and triangular grains) of C60 grains were observed at the initial growth process. Large grains with layer-by-layer step and terrace structure of C60 were observed at the terrace region of rubrene (001) surface. The growth of high-crystallinity C60 films was achieved at high substrate temperature and slow deposition rate. Long migration length on the substrate which was given by enough substrate temperature enabled the formation of large single crystalline domains.
Erbium Emission from Nanoengineered Silicon Surface (2008)

Optically active SiOx nanowires were grown on silicon by ion-implanting it with metallic impurities and annealed at 1100 °C in an Ar ambient. The implanted metals precipitate on the silicon surface and act as catalysts for nanowire growth. Ion implantation of erbium into silicon and subsequent heating in an argon ambient resulted in selective nucleation and growth of optically active silica nanowires. The bottom-up nanowire growth, mediated by vapor liquid solid mechanism, was also demonstrated for a multimetal (Au:Er) implant combinations in Si. The role of Er as a catalyst and dopant resulted in optically active silica nanowires that exhibited photoluminescence emission at 1.53 μm from an Er3+ intra-4f transition. Time resolved photoluminescence (PL) from these nanostructures indicated a luminescence lifetime of 24 ms, larger than that generally observed for Er-doped bulk silica. This increase in luminescence lifetime is attributed to a reduction in the optical density of states of Er in the nanowire samples. Infrared optical emission from erbium-doped silica nanowires on silicon holds a great potential for implementing wavelength controlled optical nanoswitches, photoresponsive devices and sensitive integrated biosensors.
Longitudinal outcomes measurement and management. Standardized practices across the continuum of care. (1998)

Longitudinal outcomes measurement involves collection of outcomes data across a continuum of care services in a patient cohort. Measurement and management of intermediate outcomes, within the varied care settings represented by the continuum, must precede measurement of long-term outcomes to provide meaningful information to providers. Once connected across a continuum of services, longitudinal outcomes measures produce powerful findings that may be used to successfully optimize the health care experience for patients and their families. The postacute continuum is ripe with research opportunities and should be pursued with vigor by outcomes researchers interested in understanding the contributions of this segment of the continuum to the production of patient outcomes.
Private Palm Beach: Tropical Style (1992)

Palm Beach, the fastest growing county in America, is home to the nation's upper crust. Both old and new money flock here for the season, and the houses that line the beach and inland waterways exhibit a remarkable range of styles and individual approaches to living under the sun. This book includes the homes of Dorothy Spreckels Munn, Lilly Pulitzer Rousseau, Edward and Pat Cook and 17 others. The book focuses on interiors and exteriors and discusses the evolution of the tropical house, and includes a source list of local architects, designers, art dealers, antique dealers, and artists.
Molecularly Ordered Ethylene-Bridged Periodic Mesoporous Organosilica Spheres with Tunable Micrometer Sizes (2006)

We report the synthesis of periodic mesoporous organosilica (PMO) spheres of a size between 3 and 14 μm. The ethylene-bridged PMO spheres were prepared via surfactant (dodecyltrimethylammonium bromide) mediated assembly of 1,2-bis(triethoxysilyl)ethylene without using any additional cosolvents and/or cosurfactants. The PMO spheres exhibit molecular-scale ordering with a periodicity of 5.6 Å due to a crystal-like arrangement of the ethylene groups in the organosilica framework. The morphology (i.e., formation of spheres) and level of mesostructural ordering in the PMO materials were dependent on the basicity of the synthesis media, while the size of the relatively monodisperse spheres was readily controlled by variations in the concentration of surfactant. The PMO materials are mesostructurally well-ordered and exhibit a high surface area (>900 m2/g) and pore volume (>0.8 cm3/g). The molecularly ordered ethylene groups within the organosilica framework were found to present a versatile and reactive functionality as demonstrated by bromination of the PMO spheres.
An all-digital time difference hold-and-replication circuit utilizing a dual pulse ring oscillator (2013)

This paper presents a time-domain analog signal hold-and-replication circuit which holds an input time interval of two signal transitions and replicates it any number of times. The proposed Time Difference Hold-and-Replication (TDHR) circuit utilizes a dual pulse ring oscillator to hold the input time interval without any time deterioration due to mismatches. The proposed TDHR circuit is implemented in a 65nm standard CMOS technology only with digital cells in the standard-cell library. It realizes 100ps to 1.2ns time interval hold and replication with the maximum error of ±50ps and consumes 0.51mW while occupying 40×60μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> area. This TDHR circuit is also used for an input time amplification and a TDC resolution enhancement application of the proposed TDHR is also demonstrated in this paper.
Inorganically filled starch based fiber reinforced composite foam materials for food packaging (1999)

A process for the manufacture of highly inorganically filled starch based fiber reinforced foam composites for food-packaging use is described. Starch, obtained from potato, corn, or other sources, is used as binder to form net shape foam composite substrates under hydrothermal conditions. The starch content is 25 to 60 wt. % of the product. Ground calcium carbonate is the principal inorganic material, being 25 to 60 wt. % of the product. The composite substrate is foamed by steam at temperatures between 160° and 220°C in a single 15 to 200 seconds step within heated molds. The organic-inorganic composite is reinforced with 5 to 20 wt. % wood or plant fiber. The substrate is rendered functional with food and beverages by thin overlay coatings that provide moisture barrier properties and additional mechanical flexibility.The product is used to package dry and wet foods and meets required food packaging standards. The substrate biodegrades rapidly in the presence of sufficient moisture or microbes. An environmental life-cycle model and an economic model are described as the additional forces to a materials model for research, development and commercialization. The primary goal of this development is to provide disposable packaging materials from renewable resources that are low in cost, low in environmental impact, and meet commercial performance requirements.
Ramping fermions in optical lattices across a Feshbach resonance (2006)

We study the properties of ultracold Fermi gases in a three-dimensional optical lattice when crossing a Feshbach resonance. By using a zero-temperature formalism, we show that three-body processes are enhanced in a lattice system in comparison to the continuum case. This poses one possible explanation for the short molecule lifetimes found when decreasing the magnetic field across a Feshbach resonance. Effects of finite temperatures on the molecule formation rates are also discussed by computing the fraction of double-occupied sites. Our results show that current experiments are performed at temperatures considerably higher than expected: lower temperatures are required for fermionic systems to be used to simulate quantum Hamiltonians. In addition, by relating the double occupancy of the lattice to the temperature, we provide a means for thermometry in fermionic lattice systems, previously not accessible experimentally. The effects of ramping a filled lowest band across a Feshbach resonance when increasing the magnetic field are also discussed: fermions are lifted into higher bands due to entanglement of Bloch states, in good agreement with recent experiments.
