Looking for Audience Costs (2001)

The methodological issues that arise in testing Fearon's argument about domestic political audience costs and signaling in international crises are examined, in particular the difficulty of finding direct evidence (1) that escalating a crisis and then backing down jeopardizes a leader's tenure in office, and (2) that democratic leaders are more vulnerable to removal in this event than are nondemocratic leaders. Tests that seek to measure the existence and magnitude of audience costs encounter severe problems of partial observability and strategic selection: the effect of audience costs on a leader's political survival can only be detected by looking at cases in which the costs are actually incurred, but strategic choice implies that the probability of incurring audience costs is a function of their value. A formal model, brief case studies, and Monte Carlo simulations are used to show that these problems bias direct tests against supporting either of the audience cost propositions. Tests based on observed audience costs understate both the mean level of audience costs in the full population and the difference in means across regime types.
Multiple genome alignment based on longest path in directed acyclic graphs (2010)

In this paper, we present a simple and efficient algorithm for multiple genome sequence alignment. Sequences of Maximal Unique Matches (MUMs) are first transformed into a multi-bipartite diagram. The diagram is then converted into a Directed Acyclic Graph (DAG). Therefore, finding the alignment is reduced to finding the longest path in the DAG, which is solvable in linear time. The experiments show that the algorithm can correctly find the alignment, and runs faster than MGA and EMAGEN. In addition, our algorithm can handle the alignments with overlapping MUMs and has both weighted and unweighted options. It provides the flexibility for the alignments depending on different needs.
Boundary-Seeking Generative Adversarial Networks (2017)

Generative adversarial networks (GANs) are a learning framework that rely on training a discriminator to estimate a measure of difference between a target and generated distributions. GANs, as normally formulated, rely on the generated samples being completely differentiable w.r.t. the generative parameters, and thus do not work for discrete data. We introduce a method for training GANs with discrete data that uses the estimated difference measure from the discriminator to compute importance weights for generated samples, thus providing a policy gradient for training the generator. The importance weights have a strong connection to the decision boundary of the discriminator, and we call our method boundary-seeking GANs (BGANs). We demonstrate the effectiveness of the proposed algorithm with discrete image and character-based natural language generation. In addition, the boundary-seeking objective extends to continuous data, which can be used to improve stability of training, and we demonstrate this on Celeba, Large-scale Scene Understanding (LSUN) bedrooms, and Imagenet without conditioning.
Use of glycosyltransferases to restore pertussis toxin receptor activity to asialoagalactofetuin. (1988)

Fetuin derivatives with enzymatically altered oligosaccharide units were tested for their ability to inhibit pertussis toxin-mediated agglutination of goose erythrocytes and the binding of 125I-labeled fetuin to pertussis toxin-coated polystyrene tubes. Fetuin oligosaccharides were sequentially degraded by treatment with: neuraminidase (asialofetuin) followed by beta-galactosidase (asialoagalactofetuin) and, lastly, with beta-N-acetylhexosaminidase (asialoagalacto-a[N-acetylglucosamino]fetuin). Asialofetuin retained only 19 and 53% of the inhibitory activity of native fetuin in the hemagglutination and 125I-fetuin binding assays, respectively. Asialoagalactofetuin showed no further reduction of inhibition in the hemagglutination system and, instead, resulted in partial recovery of inhibition in the 125I-fetuin-pertussis toxin binding assay. Asialoagalacto-a[N-acetylhexosamino]fetuin showed a further decrease in ability to inhibit pertussis toxin binding in both assays. The inhibitory activity of asialoagalactofetuin could be restored to that of native fetuin by adding back D-galactose with UDP-Gal:D-glucosyl-1,4-beta-galactosyltransferase, followed by the addition of terminal sialic acid residues with CMP-N-acetylneuraminic acid:beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosamine-alpha-2,6-N- acetylneuraminyltransferase. The data suggested that a requirement for pertussis toxin binding to fetuin may be the presence of acetamido-containing sugar groups in the nonreducing terminal position of fetuin's oligosaccharides.

Hypouricemic action of diflunisal in gouty patients: in vitro and in vivo studies. (1984)

Sixteen hyperuricemic gouty patients were treated with diflunisal, a novel salicylate, 500 mg BID. Serum and urine uric acid along with uric acid clearances were studied before and after a 7-day treatment. A clear hypouricemic action was observed, but 2 different mechanisms of action were seen when overexcretor patients and normoexcretor patients were analyzed separately. In overexcretors an allopurinol-like action was evident, whereas in normoexcretors a uricosuric action occurred. In vitro experiments showed a competitive inhibition of xanthine-oxidase exerted by diflunisal at low concentrations.
Profiling Pressure-Derivative Values - A New, Innovative Way to Estimate the Radii of Investigation in Heterogeneous Reservoir Systems (2013)

Abstract The concept of radius of investigation (ROI) has been very useful in assessing the sampled volumes of reservoirs while running well tests. This is also helpful in assessing the (pressure) stabilization times of hydrocarbon units, determining draining areas, and estimating hydrocarbon reserves. Dozens of analytical formulas that are available in the literature have been dedicated to homogeneous reservoirs. However, not much has been reported on the efforts to understand how the ROI concept can be applied to heterogeneous reservoir systems. This study presents a new approach with profiling pressure-derivative values with time in heterogeneous systems to estimate the ROI. The relationship between the reservoir permeability and the well-test derivative of the pressures measured at the wellbore has already been understood. We will introduce a similar concept to calculate the derivatives at different radial points inside the reservoir for a progressive sequence of elapsed times. By studying the profiles of the derivative values, it is possible to determine how deep the extent of the ROI is. We will also demonstrate that there exists a relationship at a given time between the derivative values at the wellbore and those inside the reservoir.
Nonspherical Noble Metal Nanoparticles: Colloid‐Chemical Synthesis and Morphology Control (2009)

Metal nanoparticles have been the subject of widespread research over the past two decades. In recent years, noble metals have been the focus of numerous studies involving synthesis, characterization, and applications. Synthesis of an impressive range of noble metal nanoparticles with varied morphologies has been reported. Researchers have made a great progress in learning how to engineer materials on a nanometer length scale that has led to the understanding of the fundamental size- and shape-dependent properties of matter and to devising of new applications. In this article, we review the recent progress in the colloid-chemical synthesis of nonspherical nanoparticles of a few important noble metals (mainly Ag, Au, Pd, and Pt), highlighting the factors that influence the particle morphology and discussing the mechanisms behind the nonspherical shape evolution. The article attempts to present a thorough discussion of the basic principles as well as state-of-the-art morphology control in noble metal nanoparticles.
The cannabinoid system and immune modulation (2003)

Studies on the effects of marijuana smoking have evolved into the discovery and description of the endocannabinoid system. To date, this system is composed of two receptors, CB1 and CB2, and endogenous ligands including anandamide, 2-arachidonoyl glycerol, and others. CB1 receptors and ligands are found in the brain as well as immune and other peripheral tissues. Conversely, CB2 receptors and ligands are found primarily in the periphery, especially in immune cells. Cannabinoid receptors are G protein-coupled receptors, and they have been linked to signaling pathways and gene activities in common with this receptor family. In addition, cannabinoids have been shown to modulate a variety of immune cell functions in humans and animals and more recently, have been shown to modulate T helper cell development, chemotaxis, and tumor development. Many of these drug effects occur through cannabinoid receptor signaling mechanisms and the modulation of cytokines and other gene products. It appears the immunocannabinoid system is involved in regulating the brain-immune axis and might be exploited in future therapies for chronic diseases and immune deficiency.
Rapid, High Level Protein Production Using DNA-based Semliki Forest Virus Vectors (1998)

Semliki Forest virus (SFV) vectors can be produced faster, and have a wider host range, than baculovirus vectors. However, the original SFV system requires in vitro manipulation of RNA. We have generated a system that is wholly DNA-based. Both the replicon vector, encoding SFV polymerase and the protein of interest, and the helper vector, encoding viral structural proteins, were modified so that expression was RNA polymerase II-dependent. Transfection of the modified replicon plasmid alone generated 20-30-fold more protein than obtained from a simple expression vector. Expression required the SFV replicase, which amplifies replicon RNA. The SFV-based vector generated 10-20-fold more protein than a plasmid based on Sindbis virus. Cotransfection of SFV replicon and helper vectors generated viral titers of around 10(6) infectious particles/ml. A single electroporation, plated on one 10-cm plate, generated enough virus (10(7) particles) to produce >500 microg of protein. Wild type, replication proficient virus was not detected in three tests utilizing almost 10(8) viral particles, a distinct advantage over a DNA Sindbis-based system in which over half the virus particles generated are fully infectious. The new SFV vectors significantly enhance the utility of this expression system.

Expression cloning and characterization of a human IL-10 receptor. (1994)

cDNA clones encoding a human IL-10R (hIL-10R) from a Burkitt lymphoma cell line, BJAB, express a 90 to 110 kDa polypeptide in COS7 cells that binds hIL-10 specifically. The predicted amino acid sequence of hIL-10R is 60% identical and 73% similar to mouse IL-10R (mIL-10R). rIL-10R expressed in an IL-3-dependent mouse pro-B cell line (Ba/F3) binds hIL-10 with high affinity (200 to 250 pM), and the transfected cells exhibit a proliferative response to hIL-10. Mouse IL-10 does not bind to hIL-10R, and hIL-10R-expressing Ba/F3 cells do not respond to the mouse cytokine, observations consistent with the known species specificity of IL-10. Expression of hIL-10R mRNA seems to be restricted mainly to human hemopoietic cells and cell lines. In a number of human T cell clones, expression of hIL-10R mRNA is down-regulated after activation of the cells with anti-CD3 Ab and phorbol ester. The hIL-10R gene is on human chromosome 11. Like mIL-10R, hIL-10R is structurally related to IFNR. Because IL-10 inhibits macrophage activation by IFN-gamma, this relationship suggests possible shared receptor or signal transduction pathway components.
Characterization of the small RNA of the bacteriophage ø29 DNA packaging machine (1987)

The prohead connector of the bacteriophage luminal diameter 29 DNA packaging machine was reconstructed with the small RNA that regulates DNA packaging in vitro. The complete sequence of the 120 nucleotide RNA proved its origination from the promoter PE1(A1) of the left early region of phi 29 DNA, the end packaged first during assembly. The prohead RNA was clearly distinct from eubacterial 5S rRNA in sequence and composition.
Enhanced efficacy of a novel controlled release paclitaxel formulation (PACLIMER delivery system) for local-regional therapy of lung cancer tumor nodules in mice. (1999)

The efficacy of systemic chemotherapy for non-small cell lung cancer (NSCLC) has improved with newer agents. However, the response rates and prolonged survival times achieved by chemotherapy remain modest, and these small gains are obtained at the cost of significant toxicity. In this study, the efficacy of a controlled release formulation of paclitaxel was compared with conventional paclitaxel in animals with human lung cancer xenografts. Paclitaxel (10%) was encapsulated in a proprietary polymer in the form of microspheres (PACLIMER Delivery System). Tumor nodules comprised of two different cell lines (A549 and H1299) were treated by a single i.p. or intratumoral administration of conventionally formulated paclitaxel or a single intratumoral injection of the PACLIMER Delivery System. In vitro testing demonstrated that paclitaxel was released slowly from the microspheres with >80% released after 90 days. Direct comparison of the highest dose for all formulations (24 mg/kg) showed that for nodules comprised of either NSCLC cell line, growth of the PACLIMER Delivery System-treated nodules were inhibited significantly more than the groups treated with conventional paclitaxel or the vehicle controls. Tumor volume doubling times for A549 and H1299 nodules treated with PACLIMER Delivery System were 60 and 35 days, respectively, compared with 10 and 11 days, respectively, in the nodules treated with the conventional paclitaxel by intratumoral administration. We conclude that intratumoral administration of the PACLIMER Delivery System may substantially increase the efficacy of paclitaxel for the therapy of local-regional NSCLC.
Inhibition of Wnt/β-catenin/CREB binding protein (CBP) signaling reverses pulmonary fibrosis (2010)

Idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia is a ravaging condition of progressive lung scarring and destruction. Anti-inflammatory therapies including corticosteroids have limited efficacy in this ultimately fatal disorder. An important unmet need is to identify new agents that interact with key molecular pathways involved in the pathogenesis of pulmonary fibrosis to prevent progression or reverse fibrosis in these patients. Because aberrant activation of the Wnt/beta-catenin signaling cascade occurs in lungs of patients with IPF, we have targeted this pathway for intervention in pulmonary fibrosis using ICG-001, a small molecule that specifically inhibits T-cell factor/beta-catenin transcription in a cyclic AMP response-element binding protein binding protein (CBP)-dependent fashion. ICG-001 selectively blocks the beta-catenin/CBP interaction without interfering with the beta-catenin/p300 interaction. We report here that ICG-001 (5 mg/kg per day) significantly inhibits beta-catenin signaling and attenuates bleomycin-induced lung fibrosis in mice, while concurrently preserving the epithelium. Administration of ICG-001 concurrent with bleomycin prevents fibrosis, and late administration is able to reverse established fibrosis and significantly improve survival. Because no effective treatment for IPF exists, selective inhibition of Wnt/beta-catenin-dependent transcription suggests a potential unique therapeutic approach for pulmonary fibrosis.
Purification and characterization of NAD+:ADP-ribosyltransferase (polymerizing) from Dictyostelium discoideum (1993)

A novel affinity-purification scheme based on the tight binding of NAD+:ADP-ribosyltransferase (polymerizing) [pADPRT; poly(ADP-ribose) polymerase; EC 2.4.2.30] to single-strand nicks in DNA, single-stranded patches and DNA ends has been developed to facilitate the purification of this enzyme from the lower eukaryote Dictyostelium discoideum. Two homogeneous forms of the enzyme, with M(r) values of 116,000 and 90,000, were prepared from D. discoideum by using poly(A) hybridized to oligo(dT)-cellulose as affinity material. The Km is 20 microM NAD+ for the 90,000-M(r) protein and 77 microM NAD+ for the 116,000-M(r) protein. The optimum conditions for the enzyme activity in vitro are 6-10 degrees C and pH 8. The time course is linear during the first 10 min of the reaction only. As in enzymes of higher eukaryotes, the activity is dependent on DNA and histone H1 and is inhibited by 3-methoxybenzamide, nicotinamide, theophylline, caffeine and thymidine.

Direct fluorescent assay of urokinase and plasminogen activators of normal and malignant cells: kinetics and inhibitor profiles. (1978)

A direct rate assay for plasminogen activator has been developed using a synthetic fluorogenic peptide substrate, 7-(N-Cbz-glycylglycylargininamido)-4-methylcoumarin trifluoroacetate. The assay correlates well with the standard 125I-labeled fibrin plate assay using highly purified urokinase, culture fluids from WI-38, Chinese hamster vary or HeLa cells, or Rous sarcoma virus-transformed chick fibroblasts as the source of plasminogen activator. The assay is sensitive, rapid, and linear throughout a wide range of enzyme concentrations. With this substrate it is possible to determine inhibitor profiles for the various plasminogen activators, independently of the interfering potential of plasmin. All of the enzymes tested are inhibited by leupeptin and antipain but not by the related aldehydes, elastatinal and chymostatin. The macromolecular inhibitors soybean trypsin inhibitor and trasylol have little or no effect on the plasminogen activators tested. This substrate should be useful for the study of the effect of various agents on functional changes in cells secreting this enzyme and also should allow kinetic measurements of potential inhibitors.
Shielding applications from an untrusted cloud with Haven (2014)

Today's cloud computing infrastructure requires substantial trust. Cloud users rely on both the provider's staff and its globally-distributed software/hardware platform not to expose any of their private data.We introduce the notion of shielded execution, which protects the confidentiality and integrity of a program and its data from the platform on which it runs (i.e., the cloud operator's OS, VM and firmware). Our prototype, Haven, is the first system to achieve shielded execution of unmodified legacy applications, including SQL Server and Apache, on a commodity OS (Windows) and commodity hardware. Haven leverages the hardware protection of Intel SGX to defend against privileged code and physical attacks such as memory probes, but also addresses the dual challenges of executing unmodified legacy binaries and protecting them from a malicious host. This work motivated recent changes in the SGX specification.
