A novel MNOS technology using gate hole injection in erase operation for embedded nonvolatile memory applications (2004)

A novel MNOS memory with gate hole injection in erase operation has been demonstrated for embedded nonvolatile memory applications. Superior characteristics with 10/spl mu/sec programming and 10msec erasing speed were obtained as compared with conventional MONOS structures. In addition, we found that the localized interface trap at source side region was generated by excess holes during erasing cycle and could be suppressed by Lg scaling. This result shows the good scalability of this technology.
Heat Shock Protein 70 Induced During Tumor Cell Killing Induces Th1 Cytokines and Targets Immature Dendritic Cell Precursors to Enhance Antigen Uptake (1999)

Previously, we reported that killing tumor cells in vivo with the HSV thymidine kinase/ganciclovir system generates potent antitumor immunity, determined in part by the mechanism by which the cells die and by the levels of inducible heat shock protein (hsp) expression induced during the process of cell death. Here, we show that induction of hsp70 expression induces an infiltrate of T cells, macrophages, and predominantly dendritic cells (DCs) into the tumors as well as an intratumoral profile of Th1 cytokine expression (IFN-gamma, TNF-alpha, and IL-12) and enhances immunogenicity via a T cell-mediated mechanism. In addition, the protection conferred by hsp70 is both tumor and cell specific. We also demonstrate that hsp70 targets immature APC to make them significantly more able to capture Ags. This is likely to optimize cross-priming of the infiltrating APC with tumor Ags, which are simultaneously being released by the dying cells. In addition, using an Myc epitope-tagged hsp70 expression vector, we present evidence that hsp70 released from dying tumor cells is taken up directly into DCs and may, therefore, be involved in direct chaperoning of Ags into DCs. Taken together, our data suggest that hsp70 induction serves to signal the immune system of the presence of an immunologically relevant (dangerous) situation against which an immune reaction should be raised.

The data suggest that arginine supplementation may improve wound healing and immune responses in the elderly.
Human amnion epithelial cells assemble tenascins and three fibronectin isoforms in the extracellular matrix (1993)

Monoclonal antibodies (MAb) were used to show that cultured human amnion epithelial (HuA) cells produce tenascins (Tn) and isoforms of cellular fibronectin (cFn). Tn polypeptides of M(r) 280,000 and 190,000, assembled into extracellular matrix (ECM) but not secreted into the culture medium by HuA cells, were electrophoretically similar to those produced by human fibroblasts as revealed with domain-specific MAbs. The results suggested that most Fn produced by HuA cells contained the extradomain (ED) A and an oncofetal domain but only a minor fraction EDB. In immunofluorescence Tn and Fn were seen in different cytoplasmic granules upon monensin-induced intracellular accumulation. Tn appeared to be deposited in the ECM in colocalization with Fn but distinctly slower. The present results show that cultured normal human epithelial cells synthesize Tn and three isoforms of cFn and secrete them by using different cytoplasmic pathways.
Improved DNA fragment length estimation in capillary electrophoresis (2008)

In CE the charged DNA strands are fractionated according to fragment lengths as they migrate through the capillary, since shorter DNA fragments pass through the sieving matrix faster. Multiplexed internal size standards are used to estimate the size of unknown DNA fragments. In the literature there are statements about migration abnormalities for the 250 and 340 bp fragments in the GeneScan-500 (GS500) internal size standards. Such anomalous migration of size standards could obviously introduce errors in the estimation of unknown fragments. Therefore, a number of analysis programs simply exclude some of these fragments. In the present work we first evaluate the effect of excluding each of the fragments in the internal size standards used in CE. Next, a method which is based on estimating the true values of the anomalous fragments is presented. The results obtained by the new method indicate a significant improvement compared to results obtained when one (or both) of the anomalous fragments in GS500 is (are) excluded or included when estimating the size of unknown DNA fragments. In the higher-molecular-weight region, the average error is reduced from 1.91 bp in ABI GeneMapper (excluding 250 bp) to 0.15 bp in the new method (using the estimated values for 250 and 340 bp). In the lower-molecular-weight region, excluding both fragments will improve the results by an average of 0.74 bp compared to ABI GeneMapper.
Ferroferric Oxide Magnetic Nanoparticles Carbon Nanotubes Nanocomposite-Based Electrochemical Sensor Applied for Detection of Bisphenol A (2013)

Multi-walled carbon nanotubes (MWNTs) combining with ferroferric oxide (Fe 3 O 4 ) nanoparticles were used for electrochemical determination of bisphenol A (BPA). Fe 3 O 4 nanoparticles with an average size of about 12 nm were synthesized. It was found that the Fe 3 O 4 -MWNTs nanocomposites-modified electrode could remarkably enhance the oxidation current of BPA. Chronoamperometry studies reveal that the amperometric response is rapid, stable, and offers a linear dependence over a range of BPA concentrations from 0.1 to 4 M. The proposed method can be used for evaluation of BPA in water samples. The electrochemical properties of the Fe 3 O 4 -MWNT nanocomposites are reasonably envisaged to be promising for providing a nanostructured platform in the development of electrochemical sensors or biosensors.
Making Watson fast (2012)

IBM Watson™ is a system created to demonstrate DeepQA technology by competing against human champions in a question-answering game designed for people. The DeepQA architecture was designed to be massively parallel, with an expectation that low latency response times could be achieved by doing parallel computation on many computers. This paper describes how a large set of deep natural-language processing programs were integrated into a single application, scaled out across thousands of central processing unit cores, and optimized to run fast enough to compete in live Jeopardy!™ games.
Recombinant Human Polyclonal Antibodies: A New Class of Therapeutic Antibodies Against Viral Infections (2006)

The mammalian immune system eliminates pathogens by generating a specific antibody response. Polyclonality is a key feature of this immune response: the immune system produces antibodies which bind to different structures on a given pathogen thereby increasing the likelihood of its elimination. The vast majority of current recombinant antibody drugs rely on monospecific monoclonal antibodies. Inherently, such antibodies do not represent the benefits of polyclonality utilized by a natural immune system and this has impeded the identification of efficacious antibody drugs against infectious agents, including viruses. The development of novel technologies has allowed the identification and manufacturing of antigen-specific recombinant polyclonal human antibodies, so-called symphobodies. This review describes the rationale for designing drugs based on symphobodies against pathogenic viruses, including HIV, vaccinia and smallpox virus, and respiratory syncytial virus.
The Yeast Nuclear Pore Complex (2000)

An understanding of how the nuclear pore complex (NPC) mediates nucleocytoplasmic exchange requires a comprehensive inventory of the molecular components of the NPC and a knowledge of how each component contributes to the overall structure of this large molecular translocation machine. Therefore, we have taken a comprehensive approach to classify all components of the yeast NPC (nucleoporins). This involved identifying all the proteins present in a highly enriched NPC fraction, determining which of these proteins were nucleoporins, and localizing each nucleoporin within the NPC. Using these data, we present a map of the molecular architecture of the yeast NPC and provide evidence for a Brownian affinity gating mechanism for nucleocytoplasmic transport.

Endoglin Is an Accessory Protein That Interacts with the Signaling Receptor Complex of Multiple Members of the Transforming Growth Factor-β Superfamily (1999)

Endoglin (CD105) is a transmembrane glycoprotein that binds transforming growth factor (TGF)-beta1 and -beta3, and coprecipitates with the Ser/Thr kinase signaling receptor complex by affinity labeling of endothelial and leukemic cells. The present study shows that in addition to TGF-beta1 and -beta3, endoglin interacts with activin-A, bone morphogenetic protein (BMP)-7, and BMP-2 but requires coexpression of the respective ligand binding kinase receptor for this association. Endoglin cannot bind ligands on its own and does not alter binding to the kinase receptors. It binds TGF-beta1 and -beta3 by associating with the TGF-beta type II receptor and interacts with activin-A and BMP-7 via activin type II receptors, ActRII and ActRIIB, regardless of which type I receptor partner is coexpressed. However, endoglin binds BMP-2 by interacting with the ligand binding type I receptors, ALK3 and ALK6. The formation of heteromeric signaling complexes was not altered by the presence of endoglin, although it was coprecipitated with these complexes. Endoglin did not interact with BMP-7 through complexes containing the BMP type II receptor, demonstrating specificity of its action. Our data suggest that endoglin is an accessory protein of multiple kinase receptor complexes of the TGF-beta superfamily.
Production of a Polyclonal Anti-Myostatin Antibody and the Effects of In Ovo Administration of the Antibody on Posthatch Broiler Growth and Muscle Mass (2007)

In this study, we produced a polyclonal antibody against unprocessed chicken myostatin and examined the effect of in ovo administration of the antibody on posthatch chicken growth and muscle mass. A PCR-amplified unprocessed chicken myostatin cDNA was cloned into an Escherichia coli expression vector, and myostatin proteins were expressed. Recombinant myostatin purified by electro-elution of the SDS-PAGE fractionated myostatin band was used as an immunogen to produce rabbit polyclonal antimyostatin antibody (pAb-AVM46). In Western blot analysis, the pAb-AVM46 showed high affinity to the myostatin propeptide, but little affinity to the mature myostatin. Two experiments examined the effect of in ovo administration of the pAb-AVM46 on posthatch chicken growth and skeletal muscle mass. In experiment 1, broilers from eggs injected once with 35 μg of the antibody into the yolk on d 3 of incubation had significantly lower combined thigh and leg weight at 4 wk posthatch than the controls that received no injection, or the broilers from eggs received the same dose of antibody into the albumen. In experiment 2, 2 different doses of the antibody (9 or 70 μg) were injected into the yolk, and the effects on body and muscle weight were examined at 5 wk posthatch. Birds from eggs injected with 70 μg of the antibody had significantly lighter (11.6%) combined thigh and leg weight than the control birds. The percentage of the combined thigh and leg weight to BW of the 70-μg group was also significantly lower than that of the control group (20.95 vs. 23.08%). The results of this study indicate that unprocessed full-length myostatin as an immunogen produced antibody populations having affinity mostly to the propeptide with little to the mature form. The decreased muscle weight observed in broilers injected with the antibody in the yolk indicates that myostatin activity was probably elevated by the binding of the antibody to the propeptide, and provides evidence that myostatin propeptide inhibits the biological activity of myostatin in broilers.
Inhaled Anesthetics and Immobility: Mechanisms, Mysteries, and Minimum Alveolar Anesthetic Concentration (2003)

Studies using molecular modeling, genetic engineering, neurophysiology/pharmacology, and whole animals have advanced our understanding of where and how inhaled anesthetics act to produce immobility (minimum alveolar anesthetic concentration; MAC) by actions on the spinal cord. Numerous ligand- and voltage-gated channels might plausibly mediate MAC, and specific amino acid sites in certain receptors present likely candidates for mediation. However, in vivo studies to date suggest that several channels or receptors may not be mediators (e.g., gamma-aminobutyric acid A, acetylcholine, potassium, 5-hydroxytryptamine-3, opioids, and alpha(2)-adrenergic), whereas other receptors/channels (e.g., glycine, N-methyl-D-aspartate, and sodium) remain credible candidates.

The Horizon Alliance case study: Implementation of carbon accounting and sustainability in design and construction (2009)

The Darra to Springfield Transport Corridor Project is a major initiative of the Queensland Government to service the future needs of the growing western corridor region. It is the first major integrated road and rail project for south east Queensland. Stage 1 of the project includes building a new passenger railway line to Richlands, constructing a railway station, bus interchange and park and ride facilities at Richlands and duplicating the Centenary Highway from two to four lanes north of the Logan Motorway interchange. Stage 1 is due for completion in 2011 at an estimated cost of $800 million. Stage 1 of the project is being delivered by The Horizon Alliance - a collaboration between QR Limited, the Department of Transport and Main Roads, John Holland Pty Ltd, Kellogg Brown and Root Pty Ltd (KBR) and GHD Pty Ltd. One of several options originally proposed for Stage 2 was the upgrade of the Logan Motorway interchange and a new railway station to be built at Springfield near the Orion Springfield Town Centre. Provision would be made for future stations at Ellen Grove and Springfield Lakes. This paper focuses on a number of sustainability opportunities which have been identified for consideration if the project is extended as per the above option. Sustainability opportunities have been identified for the potential future works through the Project Sustainability Framework. As a result of the implementation of the framework it was identified that greenhouse gas emissions generated during operation of the road and rail infrastructure should be investigated. The intent of the investigation was to consider whether innovative changes in the design would reduce the emissions generated during the operation of the infrastructure over its design life.
Antibody-induced engagement of beta 2 integrins on adherent human neutrophils triggers activation of p21ras through tyrosine phosphorylation of the protooncogene product Vav. (1996)

It is known that beta 2 integrins are crucial for leukocyte cell-cell and cell-matrix interactions, and accumulating evidence now suggests that integrins serve not only as a structural link but also as a signal-transducing unit that controls adhesion-induced changes in cell functions. In the present study, we plated human neutrophils on surface-bound anti-beta 2 (CD18) antibodies and found that the small GTP-binding protein p21ras is activated by beta 2 integrins. Pretreatment of the cells with genistein, a tyrosine kinase inhibitor, led to a complete block of p21ras activation, an effect that was not achieved with either U73122, which abolishes the beta 2 integrin-induced Ca2+ signal, or wortmannin, which totally inhibits the phosphatidylinositol 3-kinase activity. Western blot analysis revealed that antibody-induced engagement of beta 2 integrins causes tyrosine phosphorylation of several proteins in the cells. One of these tyrosine-phosphorylated proteins had an apparent molecular mass of 95 kDa and was identified as the protooncogene product Vav, a p21ras guanine nucleotide exchange factor that is specifically expressed in cells of hematopoietic lineage. A role for Vav in the activation of p21ras is supported by the observations that antibody-induced engagement of beta 2 integrins causes an association of Vav with p21ras and that the effect of genistein on p21ras activation coincided with its ability to inhibit both the tyrosine phosphorylation of Vav and the Vav-p21ras association. Taken together, these results indicate that antibody-induced engagement of beta 2 integrins on neutrophils triggers tyrosine phosphorylation of Vav and, possibly through its association, a downstream activation of p21ras.
S-layers: principles and applications (2014)

Monomolecular arrays of protein or glycoprotein subunits forming surface layers (S-layers) are one of the most commonly observed prokaryotic cell envelope components. S-layers are generally the most abundantly expressed proteins, have been observed in species of nearly every taxonomical group of walled bacteria, and represent an almost universal feature of archaeal envelopes. The isoporous lattices completely covering the cell surface provide organisms with various selection advantages including functioning as protective coats, molecular sieves and ion traps, as structures involved in surface recognition and cell adhesion, and as antifouling layers. S-layers are also identified to contribute to virulence when present as a structural component of pathogens. In Archaea, most of which possess S-layers as exclusive wall component, they are involved in determining cell shape and cell division. Studies on structure, chemistry, genetics, assembly, function, and evolutionary relationship of S-layers revealed considerable application potential in (nano)biotechnology, biomimetics, biomedicine, and synthetic biology.
Secretion, Surface Localization, Turnover, and Steady State Expression of Protein Disulfide Isomerase in Rat Hepatocytes (1995)

Protein disulfide isomerase in isolated rat hepatocytes was present at a concentration of 7 micrograms/mg cell protein, representing a approximately 2-fold enrichment compared to isolated hepatic non-parenchymal cells. Though localized mainly in microsomal fractions of hepatocytes, direct immunofluorescence and cell surface radioiodination followed by immunoprecipitation revealed the presence of M(r) 57,000 disulfide isomerase at the cell surface. Electrostatic interaction of the protein with the cell surface was suggested by susceptibility to carbonate washing. Metabolic radiolabeling and immunoprecipitation studies also indicated that some of the newly synthesized M(r) 57,000 disulfide isomerase was secreted. Treatment of cells with colchicine markedly reduced the recovery of disulfide isomerase from the media, indicating microtubular-directed secretion of the protein. Partial staphlococcal V8 proteolytic digestion of the secreted protein revealed a peptide pattern similar to that of the cellular protein. Immunoprecipitation with antibody specific to the -KDEL peptide retention sequence confirmed the presence of this sequence in the secreted protein. Studies of the turnover of disulfide isomerase revealed a half-life of approximately 96 h. Treatment of cells with tunicamycin or heat shock resulted in an increased recovery of newly synthesized disulfide isomerase from cell lysates but diminished recovery from the media. The secretion and cell surface distribution of disulfide isomerase in hepatocytes may be important for the pathogenesis of immune mediated liver injury.
Development of atopic dermatitis-like skin lesion with IgE hyperproduction in NC/Nga mice (1997)

Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen especially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, spontaneously appeared on the face, neck, ears and dorsal skin of inbred NC/Nga mice when they were raised in non-sterile (conventional) circumstances, but not under specific pathogen-free conditions. Plasma levels of total IgE in conventional NC/Nga mice were markedly elevated from 8 weeks of age, correlating with clinical skin severity of dermatitis. Immunohistochemical examination of the skin lesion showed increased numbers of mast cells and CD4+ T cells containing IL-4 necessary for IgE synthesis. Thus, NC/Nga mice suffered from dermatitis very similar to human AD with IgE hyperproduction, which may be triggered by some environmental factor(s).
A Nonhuman Primate Brain–Computer Typing Interface (2016)

Brain-computer interfaces (BCIs) record brain activity and translate the information into useful control signals. They can be used to restore function to people with paralysis by controlling end effectors such as computer cursors and robotic limbs. Communication neural prostheses are BCIs that control user interfaces on computers or mobile devices. Here we demonstrate a communication prosthesis by simulating a typing task with two rhesus macaques implanted with electrode arrays. The monkeys used two of the highest known performing BCI decoders to type out words and sentences when prompted one symbol/letter at a time. On average, Monkeys J and L achieved typing rates of 10.0 and 7.2 words per minute (wpm), respectively, copying text from a newspaper article using a velocity-only two dimensional BCI decoder with dwell-based symbol selection. With a BCI decoder that also featured a discrete click for key selection, typing rates increased to 12.0 and 7.8 wpm. These represent the highest known achieved communication rates using a BCI. We then quantified the relationship between bitrate and typing rate and found it approximately linear: typing rate in wpm is nearly three times bitrate in bits per second. We also compared the metrics of achieved bitrate and information transfer rate and discuss their applicability to real-world typing scenarios. Although this study cannot model the impact of cognitive load of word and sentence planning, the findings here demonstrate the feasibility of BCIs to serve as communication interfaces and represent an upper bound on the expected achieved typing rate for a given BCI throughput.
