Impaired trace eyeblink conditioning in bilateral, medial-temporal lobe amnesia. (1997)

Trace eyeblink classical conditioning was assessed in patients with bilateral medial-temporal amnesia and matched control participants who had previously shown equivalent delay eyeblink conditioning (J. D. E. Gabrieli et al., 1995). The silent trace interval varied for durations of 500, 750, or 1,000 ms in successive sessions separated by at least 2 weeks; extinction trials followed each session. Patients with amnesia produced significantly fewer conditioned responses (CRs) than did control participants at all trace intervals. Both groups produced fewer CRs as the trace interval lengthened. Thus, the temporal lobe memory system in humans makes an essential contribution to normal acquisition in trace, but not delay, classical eyeblink conditioning.
Panel: E-Government: Are there Different Perspectives? (2004)

The area of e-Government has rapidly become the focus of much attention amongst academics and practitioners.Led by the drive to streamline government services to citizens and increase participation in the governing and democratic process amongst citizens, government agencies and bodies at different levels are implementing information systems and undergoing process changes under the pervasive umbrella of "e-Government".Yet, what exactly the term means is unclear.Terms such as e-Democracy, e-Voting, e-Services and e-Procurement are used interchangeably and often confusedly.In addition, there seems to be as many perspectives of the term as there are implementations at least across national boundaries.To help us achieve conceptual clarity, we propose this panel.Members of our proposed panel will present their work and experiences in different regions of Europe and North America.Specifically, we will address these questions: What exactly is meant by "e-Government"?Is it a distinct field within IS research?What are the key issues that e-Government researchers need to address?Is e-Government conceptualized and practiced differently in different parts of the world?Specifically, is there a "Scandinavian perspective" and a "North American perspective"?What have we, as e-Government researchers, done well so far?What have we not done well?

Our integrated information of sequencing-based genomic studies and tumor transcriptomes with drug treatment in NPC-PDX models provided guidelines for personalized precision treatments and revealed a cyclin-dependent kinase inhibitor Palbociclib as a novel candidate drug for NPC.
Characterization and Distribution of Water-repellent, Self-cleaning Plant Surfaces (1997)

During the last 20 years, a wealth of data dealing with scanning electron microscopy of plant surfaces has been published. The ultrastructure of epidermal surfaces has been investigated with respect to taxonomic, as well as functional aspects. Within the latter, water-repellency has received much attention and has been well documented. Water-repellency is based on surface roughness caused by different microstructures (trichomes, cuticular folds and wax crystals), together with the hydrophobic properties of the epicuticular wax. In addition, contaminating particles are carried away by water droplets, resulting in a cleaned surface (Lotus-effect). Therefore, rough, waxy leaves are not only water-repellent but anti-adhesive with respect to particulate contamination. Based on 200 water-repellent plant species, the present paper surveys micromorphological characteristics of anti-adhesive plant surfaces. Leaves that are permanently water-repellent can be differentiated by distictively convex to papillose epidermal cells and a very dense layer of epicuticular waxes. Leaves that are water-repellent for only a limited period of time have only slightly convex epidermal cells and often have a less dense wax layer. Finally, an overview is given on the occurrence of water-repellency among different life forms and within different habitats. Water-repellency is concentrated in herbaceous species, while it is rare in trees. Among different habitats, subtropical regions, wetlands and disturbed areas appear to have more species with water-repellent leaves. The importance of roughness and water-repellency, respectively, as the basis of an anti-adhesive, self-cleaning surface, in comparison to other functions of microstructures, is discussed.
Repression of α-synuclein expression and toxicity by microRNA-7 (2009)

alpha-Synuclein is a key protein in Parkinson's disease (PD) because it accumulates as fibrillar aggregates in pathologic hallmark features in affected brain regions, most notably in nigral dopaminergic neurons. Intraneuronal levels of this protein appear critical in mediating its toxicity, because multiplication of its gene locus leads to autosomal dominant PD, and transgenic animal models overexpressing human alpha-synuclein manifest impaired function or decreased survival of dopaminergic neurons. Here, we show that microRNA-7 (miR-7), which is expressed mainly in neurons, represses alpha-synuclein protein levels through the 3'-untranslated region (UTR) of alpha-synuclein mRNA. Importantly, miR-7-induced down-regulation of alpha-synuclein protects cells against oxidative stress. Further, in the MPTP-induced neurotoxin model of PD in cultured cells and in mice, miR-7 expression decreases, possibly contributing to increased alpha-synuclein expression. These findings provide a mechanism by which alpha-synuclein levels are regulated in neurons, have implications for the pathogenesis of PD, and suggest miR-7 as a therapeutic target for PD and other alpha-synucleinopathies.
EFFORT: Efficient and effective bot malware detection (2012)

To detect bots, a lot of detection approaches have been proposed at host or network level so far and both approaches have clear advantages and disadvantages. In this paper, we propose EFFORT, a new host-network cooperated detection framework attempting to overcome shortcomings of both approaches while still keeping both advantages, i.e., effectiveness and efficiency. Based on intrinsic characteristics of bots, we propose a multi-module approach to correlate information from different host- and network-level aspects and design a multi-layered architecture to efficiently coordinate modules to perform heavy monitoring only when necessary. We have implemented our proposed system and evaluated on real-world benign and malicious programs running on several diverse real-life office and home machines for several days. The final results show that our system can detect all 15 real-world bots (e.g., Waledac, Storm) with low false positives (0.68%) and with minimal overhead. We believe EFFORT raises a higher bar and this host-network cooperated design represents a timely effort and a right direction in the malware battle.
Cholesterol Depletion of Human Immunodeficiency Virus Type 1 and Simian Immunodeficiency Virus with β-Cyclodextrin Inactivates and Permeabilizes the Virions: Evidence for Virion-Associated Lipid Rafts (2003)

Recent evidence suggests that human immunodeficiency virus type 1 (HIV-1) particles assemble and bud selectively through areas in the plasma membrane of cells that are highly enriched with glycosylphosphatidylinositol-anchored proteins and cholesterol, called lipid rafts. Since cholesterol is required to maintain lipid raft structure and function, we proposed that virion-associated cholesterol removal with the compound 2-hydroxy-propyl-beta-cyclodextrin (beta-CD) might be disruptive to HIV-1 and simian immunodeficiency virus (SIV). We examined the effect of beta-CD on the structure and infectivity of cell-free virions. We found that beta-CD inactivated HIV-1 and SIV in a dose-dependent manner and permeabilized the viral membranes, resulting in the loss of mature Gag proteins (capsid, matrix, nucleocapsid, p1, and p6) without loss of the envelope glycoproteins. SIV also lost reverse transcriptase (RT), integrase (IN), and viral RNA. IN appeared to be only slightly diminished in HIV-1, and viral RNA, RT, matrix, and nucleocapsid proteins were retained in HIV-1 but to a much lesser degree. Host proteins located internally in the virus (actin, moesin, and ezrin) and membrane-associated host proteins (major histocompatibility complex classes I and II) remained associated with the treated virions. Electron microscopy revealed that under conditions that permeabilized the viruses, holes were present in the viral membranes and the viral core structure was perturbed. These data provide evidence that an intact viral membrane is required to maintain mature virion core integrity. Since the viruses were not fixed before beta-CD treatment and intact virion particles were recovered, the data suggest that virions may possess a protein scaffold that can maintain overall structure despite disruptions in membrane integrity.
Monoclonal antibodies against 5'-nucleotidase from a human pancreatic tumor cell line: their characterization and inhibitory capacity on tumor cell adhesion to fibronectin substratum. (1992)

Four mouse monoclonal antibodies (PTN63, PTN108, PTN124, PTN514) against the ecto-5'-nucleotidase purified from a human pancreatic adenocarcinoma cell line (PaTu II) have been raised and characterized. All four monoclonal antibodies recognize the protein moiety of the glycosylated ecto-5'-nucleotidase. In competition assays it was demonstrated that three of the antibodies (PTN63, PTN108, PTN514) recognize different epitopes within the protein moiety. Furthermore, PTN108, PTN124, and PTN514 reduced the 5'-nucleotidase AMPase activity in contrast to PTN63 having no inhibitory effect. The antibodies show no cross-reactivity with ecto-5'-nucleotidases from rat liver, bull seminal plasma, chicken gizzard and human peripheral blood cells. When assayed by indirect immunofluorescence the antibodies react with the plasma membrane of human pancreatic tumor cells with varying staining intensity. Immunocytochemistry on paraffin sections of normal human pancreas revealed a prominent staining of the pancreatic duct cells. No staining of the acinar and islet cells could be detected. Thus, 5'-nucleotidase is a marker enzyme for pancreatic duct cells and can be used to determine the origin of pancreatic tumor cells. PTN63 reduced the attachment to fibronectin substratum of a human pancreatic adenocarcinoma tumor cell line possessing a high amount of plasma membrane bound ecto-5'-nucleotidase, but had no effect on a cell line lacking the membrane bound AMPase. In contrast, PTN108 and PTN514, which inhibit the AMPase activity, exhibited no influence on the adhesion of human pancreatic tumor cells to fibronectin substratum.
Oncolytic vesicular stomatitis virus quantitatively and qualitatively improves primary CD8+T-cell responses to anticancer vaccines (2013)

The ability of heterologous prime-boost vaccination to elicit robust CD8<sup>+</sup> T cell responses has been well documented. In contrast, relatively little is known about how this immunotherapeutic strategy impacts the functional qualities of expanded T cells in the course of effector and memory responses. Using vesicular stomatitis virus (VSV) as a boosting vector in mice, we demonstrate that a massive secondary expansion of CD8<sup>+</sup> T cells can be achieved shortly after priming with recombinant adenoviral vectors. Importantly, VSV-boosted CD8<sup>+</sup> T cells were more potent than those primed by adenoviruses only, as measured by cytokine production, granzyme B expression, and functional avidity. Upon adoptive transfer, equivalent numbers of VSV-expanded CD8<sup>+</sup> T cells were more effective (on a per-cell basis) in mediating antitumor and antiviral immunity than T cells only primed with adenoviruses. Furthermore, VSV boosting accelerated the progression of expanded CD8<sup>+</sup> T lymphocytes to a central memory phenotype, thereby altering the effector memory profile typically associated with adenoviral vaccination. Finally, the functional superiority of VSV-expanded T cells remained evident 100 d after boosting, suggesting that VSV-driven immunological responses are of sufficient duration for therapeutic applications. Our data strongly support the choice of VSV as a boosting vector in prime-boost vaccination strategies, enabling a rapid amplification of CD8<sup>+</sup> T cells and improving the quality of expanded T cells during both early and late immunological responses.
A Novel Tumor Suppressor Protein Promotes Keratinocyte Terminal Differentiation via Activation of Type I Transglutaminase (2003)

Tazarotene-induced protein 3 (TIG3) is a recently discovered regulatory protein that is expressed in the suprabasal epidermis. In the present study, we show that TIG3 regulates keratinocyte viability and proliferation. TIG3-dependent reduction in keratinocyte viability is accompanied by a substantial increase in the number of sub-G1 cells, nuclear shrinkage, and increased formation of cornified envelope-like structures. TIG3 localizes to the membrane fraction, and TIG3-dependent differentiation is associated with increased type I transglutaminase activity. Microscopic localization and isopeptide cross-linking studies suggest that TIG3 and type I transglutaminase co-localize in membranes. Markers of apoptosis, including caspases and poly(ADP-ribose) polymerase, are not activated by TIG3, and caspase inhibitors do not stop the TIG3-dependent reduction in cell viability. Truncation of the carboxyl-terminal membrane-anchoring domain results in a complete loss of TIG3 activity. The morphology of the TIG3-positive cells and the effects on cornified envelope formation suggest that TIG3 is an activator of terminal keratinocyte differentiation. Our studies suggest that TIG3 facilitates the terminal stages in keratinocyte differentiation via activation of type I transglutaminase.
Integrating High Performance File Systems in a Cloud Computing Environment (2012)

This paper outlines our ongoing efforts to effectively integrate a parallel file system in a cloud environment. We investigate how a parallel file system (PFS) can be effectively integrated and provided as a service to cloud users running High Performance Computing (HPC) applications, and what would be the performance and security implications of such a service. A critical requirement of running today's dataintensive HPC applications is the availability of a parallel high performance storage system. The objectives of our work are two-fold: first, to identify and evaluate the possible ways to deploy a PFS in a cloud infrastructure, and second, to design a framework to provide the PFS as a service inside a cloud-management framework which would allow users to provision and configure PFS storage dynamically and securely, in much the same way they can provision instances and volumes. Initial results indicate that among the options evaluated, the best filesystem performance can be obtained by providing a native parallel file-system installation as a service and using file-system passthrough from the virtual machine instances to access the files directly.
Adriamycin analogues. Preparation and biological evaluation of some N-(trifluoroacetyl)-14-O-[N-acetylamino)acyl]adriamycin derivatives (1986)

In connection with structure-activity studies related to the novel DNA-nonbinding adriamycin analogues N-(trifluoroacetyl)adriamycin 14-valerate (AD 32) and N-(trifluoroacetyl)adriamycin 14-O-hemiadipate (AD 143), we have now prepared a series of N-(trifluoroacetyl)adriamycin derivatives with N-acylamino acid esters at the 14-carbinol position. Target compounds were made by reaction of N-(trifluoroacetyl)-14-iododaunorubicin with the sodium salts of N-acylamino acids generally in dimethylformamide-ethylene glycol solvent. Products were evaluated for in vitro growth-inhibitory activity and, to a limited extent, in vivo antitumor activity in the murine P388 leukemia system. ID50 values for the target compounds vs. cultured CCRF-CEM cells were generally in the same range as those for the above-mentioned DNA nonbinding adriamycin analogues. Of the four compounds tested for in vivo activity, although none was as effective as N-(trifluoroacetyl)adriamycin 14-valerate, all showed significant activity in the P388 assay system, with three of the compounds, at the doses used, being essentially equiactive with an optimal dose of adriamycin. Studies on the rate of esterase-mediated deacylation of the products, in a defined system containing unfractionated mouse serum as the source of enzyme, showed no relationship between the in vitro and in vivo activities of these compounds and the relative ease at which the side-chain ester substituents were hydrolyzed.

Combined use of autoantibodies (IA-2 autoantibody, GAD autoantibody, insulin autoantibody, cytoplasmic islet cell antibodies) in type 1 diabetes: Combinatorial Islet Autoantibody Workshop. (1998)

The aim of this workshop was to assess the ability of individual autoantibody (ab) assays and their use in combination to discriminate between type 1 diabetic and control sera. Coded aliquots of sera were measured in a total of 119 assays by 49 participating laboratories in 17 countries. The sera were from 51 patients with new onset type 1 diabetes and 101 healthy control subjects with no family history of diabetes. In the final analysis, data on diabetic sera were restricted to 43 subjects younger than age 30 years. The laboratories were asked to report results for these sera using their currently available anti-islet autoantibody assays. In addition, they were asked to combine information from their assays to classify sera as having high, moderate, or low probability of originating from a patient with type 1 diabetes. Actual strategies for combining assays were determined by each laboratory. There were no significant differences in sensitivity among 19 radioimmunoassays (RIAs) for IA-2 autoantibodies (cytoplasmic islet cell antibody [ICA] 512) using different constructs that included the intracellular portion of the molecule (mean sensitivity 73%). However, an enzyme-linked immunosorbent assay (ELISA) using the extracellular portion of the IA-2 molecule did not discriminate between diabetic and control sera. Among GAD autoantibody assays that achieved sensitivity >70%, 26 were RIAs and one was an ELISA. When the sera were ranked according to their autoantibody levels, the concordance for insulin autoantibodies (IAAs) in different laboratories was markedly less than for IA-2ab and GADab. Using a combination of autoantibody assays, several laboratories achieved excellent discrimination between diabetic and control sera (sensitivity up to 80% with false-positive rate of 0%). A variety of strategies for combining information from different assays were successful (e.g., those including and excluding ICA), and no one strategy emerged as clearly superior. In conclusion, IA-2/ICA512 autoantibodies are a marker of type 1 diabetes and can be measured consistently by most assays. Several different strategies for combining assays achieved high sensitivity with a low false-positive rate.
Conservation of Substrate Recognition Mechanisms by tRNA Splicing Endonucleases (1998)

Accuracy in transfer RNA (tRNA) splicing is essential for the formation of functional tRNAs, and hence for gene expression, in both Eukaryotes and Archaea. The specificity for recognition of the tRNA precursor (pre-tRNA) resides in the endonuclease, which removes the intron by making two independent endonucleolytic cleavages. Although the eukaryal and archaeal enzymes appear to use different features of pre-tRNAs to determine the sites of cleavage, analysis of hybrid pre-tRNA substrates containing eukaryal and archaeal sequences, described here, reveals that the eukaryal enzyme retains the ability to use the archaeal recognition signals. This result indicates that there may be a common ancestral mechanism for recognition of pre-tRNA by proteins.
OSI-930: A Novel Selective Inhibitor of Kit and Kinase Insert Domain Receptor Tyrosine Kinases with Antitumor Activity in Mouse Xenograft Models (2006)

OSI-930 is a novel inhibitor of the receptor tyrosine kinases Kit and kinase insert domain receptor (KDR), which is currently being evaluated in clinical studies. OSI-930 selectively inhibits Kit and KDR with similar potency in intact cells and also inhibits these targets in vivo following oral dosing. We have investigated the relationships between the potency observed in cell-based assays in vitro, the plasma exposure levels achieved following oral dosing, the time course of target inhibition in vivo, and antitumor activity of OSI-930 in tumor xenograft models. In the mutant Kit-expressing HMC-1 xenograft model, prolonged inhibition of Kit was achieved at oral doses between 10 and 50 mg/kg and this dose range was associated with antitumor activity. Similarly, prolonged inhibition of wild-type Kit in the NCI-H526 xenograft model was observed at oral doses of 100 to 200 mg/kg, which was the dose level associated with significant antitumor activity in this model as well as in the majority of other xenograft models tested. The data suggest that antitumor activity of OSI-930 in mouse xenograft models is observed at dose levels that maintain a significant level of inhibition of the molecular targets of OSI-930 for a prolonged period. Furthermore, pharmacokinetic evaluation of the plasma exposure levels of OSI-930 at these effective dose levels provides an estimate of the target plasma concentrations that may be required to achieve prolonged inhibition of Kit and KDR in humans and which would therefore be expected to yield a therapeutic benefit in future clinical evaluations of OSI-930.
Carnero v. Boston Scientific Corporation: Interpreting the Extraterritorial Effect of the Civil Whistleblower Protection Provision of the Sarbanes-Oxley Act (2006)

This Comment argues that, had the First Circuit employed the effects test, the court could have logically reached the conclusion that the Whistleblower Provision of the Sarbanes-Oxley Act should have extraterritorial effect.
