The essential yeast Tcp1 protein affects actin and microtubules. (1994)

Previously, we showed that the yeast Saccharomyces cerevisiae cold-sensitive mutation tcp1-1 confers growth arrest concomitant with cytoskeletal disorganization and disruption of microtubule-mediated processes. We have identified two new recessive mutations, tcp1-2 and tcp1-3, that confer heat- and cold-sensitive growth. Cells carrying tcp1 alleles were analyzed after exposure to the appropriate restrictive temperatures by cell viability tests, differential contrast microscopy, fluorescent, and immunofluorescent microscopy of DNA, tubulin, and actin and by determining the DNA content per cell. All three mutations conferred unique phenotypes indicative of cytoskeletal dysfunction. A causal relationship between loss of Tcp1p function and the development of cytoskeletal abnormalities was established by double mutant analyses. Novel phenotypes indicative of allele-specific genetic interactions were observed when tcp1-1 was combined in the same strain with tub1-1, tub2-402, act1-1, and act1-4, but not with other tubulin or actin mutations or with mutations in other genes affecting the cytoskeleton. Also, overproduction of wild-type Tcp1p partially suppressed growth defects conferred by act1-1 and act1-4. Furthermore, Tcp1p was localized to the cytoplasm and the cell cortex. Based on our results, we propose that Tcp1p is required for normal development and function of actin and microtubules either through direct or indirect interaction with the major cytoskeletal components.
Recursive noise estimation using iterative stochastic approximation for stereo-based robust speech recognition (2005)

We present an algorithm for recursive estimation of parameters in a mildly nonlinear model involving incomplete data. In particular, we focus on the time-varying deterministic parameters of additive noise in the nonlinear model. For the nonstationary noise that we encounter in robust speech recognition, different observation data segments correspond to different noise parameter values. Hence, recursive estimation algorithms are more desirable than batch algorithms, since they can be designed to adaptively track the changing noise parameters. One such design based on the iterative stochastic approximation algorithm in the recursive-EM framework is described. This new algorithm jointly adapts time-varying noise parameters and the auxiliary parameters introduced to give a linear approximation of the nonlinear model. We present stereo-based robust speech recognition results for the AURORA task, which demonstrate the effectiveness of the new algorithm compared with a more traditional, MMSE noise estimation technique under otherwise identical experimental conditions.
MACC1 Suppresses Cell Apoptosis in Hepatocellular Carcinoma by Targeting the HGF/c-MET/AKT Pathway (2015)

This investigation revealed that MACC1 overexpression predicted worse prognosis after liver resection, which was attributed to the repression of HCC cell apoptosis via a molecular mechanism in which MACC1 accelerated the activation of the HGF/c-MET/PI3K/AKT pathway and phosphorylated BAD, Caspase 9 and FKHRL1, ultimately preventing their nuclear translocation and their pro-apoptotic function.
CD45RB Is a Novel Molecular Therapeutic Target to Inhibit Aβ Peptide-Induced Microglial MAPK Activation (2008)

In summary, p38 MAPK is another novel signaling pathway, besides p44/42, in which CD45RB cross-linking negatively regulates microglial Abeta phagocytosis while increasing potentially neurotoxic inflammation. Therefore, agonism of CD45RB PTP activity may be an effective therapeutic target for novel agents to treat AD due to its Abeta lowering, and inflammation reducing, properties that are particularly targeted at microglial cells. Such treatments may be more effective with less potential to produce systemic side-effects than therapeutics which induce non-specific, systemic down-regulation of inflammation.
The Dipole Approximation Method And ItsCoupling With The Regular Boundary ElementMethod For Efficient Electrical ImpedanceTomography (1970)

The Electrical Impedance Tomography (BIT) utilizes CPU time-consuming minimization techniques for imaging an object. In this paper we present a computationally fast method for the forward/inverse BIT problem based on an asymptotic solution to Laplace's equation for an imaged domain with a small size inclusion situated inside of it. In this solution the principal term is represented by a dipole term. The computational time required by an BIT problem using the Dipole Approximation (DA) can be two orders of magnitude smaller than when using regular BEM. Results of numerical tests show a substantial improvement in the speed of the inverse problem solution when using the DA BEM approach.
Music feels like moods feel (2014)

While it is widely accepted that music evokes moods, there is disagreement over whether music-induced moods are relevant to the aesthetic appreciation of music as such. The arguments against the aesthetic relevance of music-induced moods are: (1) moods cannot be intentionally directed at the music and (2) music-induced moods are highly subjective experiences and are therefore a kind of mind-wandering. This paper presents a novel account of musical moods that avoids these objections. It is correct to say that a listener's entire mood is not relevant to the aesthetic appreciation of music. However, the experience of mood consists of having different feelings. Music induces feelings that are intentionally directed at the music and clusters of these feelings can be recognized as typical of a specific mood. Therefore, mood-feelings are relevant to the aesthetic appreciation of music.
Pattern Roughness Mitigation of 22 nm Lines and Spaces: The Impact of a H2Plasma Treatment (2014)

As the semiconductor industry pursues Moore's law, the demand to obtain smaller features continues. Extreme ultraviolet (EUV) lithography remains one of the primary options for sub-20 nm patterns. However, the technology struggles to meet the line width roughness (LWR) specifications. In this article, we present the significance of plasma treatment as a roughness smoothing technique. Two EUV photoresists with 22 nm lines are exposed to various plasma processes. We highlight the advantages of a hydrogen plasma treatment and its vacuum ultraviolet (VUV) emission as an optimal smoothing process and discuss the effect of photoresist thickness, initial LWR and the VUV plasma emission. Even though a H2 plasma treatment results in a successful reduction of LWR/LER, the target value of below 2nm is not yet achieved.
Fc receptor stimulation of phosphatidylinositol 3-kinase in natural killer cells is associated with protein kinase C-independent granule release and cell-mediated cytotoxicity. (1994)

Although diverse signaling events are initiated by stimulation of multichain immune recognition receptors on lymphocytes, it remains unclear as to which specific signal transduction pathways are functionally linked to granule exocytosis and cellular cytotoxicity. In the case of natural killer (NK) cells, it has been presumed that the rapid activation of protein kinase C (PKC) enables them to mediate antibody-dependent cellular cytotoxicity (ADCC) and "natural" cytotoxicity toward tumor cells. However, using cloned human NK cells, we determined here that Fc receptor stimulation triggers granule release and ADCC through a PKC-independent pathway. Specifically, pretreatment of NK cells with the selective PKC inhibitor, GF109203X (using concentrations that fully blocked phorbol myristate acetate/ionomycin-induced secretion) had no effect on FcR-initiated granule release or ADCC. In contrast, FcR ligation led to the rapid activation of phosphatidylinositol 3-kinase (PI 3-kinase), and inhibition of this enzyme with the selective inhibitor, wortmannin, blocked FcR-induced granule release and ADCC. Additional experiments showed that, whereas FcR-initiated killing was wortmannin sensitive and GF109203X insensitive, natural cytotoxic activity toward the tumor cell line K562 was wortmannin insensitive and GF109203X sensitive. Taken together, these results suggest that: (a) PI 3-kinase activation induced by FcR ligation is functionally coupled to granule exocytosis and ADCC; and (b) the signaling pathways involved in ADCC vs natural cytotoxicity are distinct.
Identification of the Fibroblast Growth Factor (FGF)-interacting Domain in a Secreted FGF-binding Protein by Phage Display (2005)

Fibroblast growth factor-binding proteins (FGF-BP) are secreted carrier proteins that release fibroblast growth factors (FGFs) from the extracellular matrix storage and thus enhance FGF activity. Here we have mapped the interaction domain between human FGF-BP1 and FGF-2. For this, we generated T7 phage display libraries of N-terminally and C-terminally truncated FGF-BP1 fragments that were then panned against immobilized FGF-2. From this panning, a C-terminal fragment of FGF-BP1 (amino acids 193-234) was identified as the minimum binding domain for FGF. As a recombinant protein, this C-terminal fragment binds to FGF-2 and enhances FGF-2-induced signaling in NIH-3T3 fibroblasts and GM7373 endothelial cells, as well as mitogenesis and chemotaxis of NIH-3T3 cells. The FGF interaction domain in FGF-BP1 is distinct from the heparin-binding domain (amino acids 110-143), and homology modeling supports the notion of a distinct domain in the C terminus that is conserved across different species. This domain also contains conserved positioning of cysteine residues with the Cys-214/Cys-222 positions in the human protein predicted to participate in disulfide bridge formation. Phage display of a C214A mutation of FGF-BP1 reduced binding to FGF-2, indicating the functional significance of this disulfide bond. We concluded that the FGF interaction domain is contained in the C terminus of FGF-BP1.
Benzothiadiazole-Triphenylamine Derivatives as Donor Materials for Bulk-Heterojunction Organic Solar Cells (2010)

We studied three different benzothiadiazole-triphenylamine (BTD-TPA) derivatives as donor materials for bulk-heterojunction organic photovoltaics (OPVs), and investigated the resulting OPV performance. We found that the increased concentration of (6,6)-phenyl C61 butyric acid methyl ester (PCBM) as acceptor material and the decreased thickness of active layers led to high-performance OPVs with sufficient percolated pathways for the photogenerated mobile carriers to the respective electrodes. The highest performance was observed for OPVs based on BTD-Th-TPA:PCBM (1:2, w/w) with thickness of 76 nm, yielding a power-conversion efficiency of 1.0% under 100 mW/cm2 of AM 1.5 illumination and incident photon conversion efficiency of 32% at a wavelength of 540 nm.
Synthèse d'arylhydroxyspirocétals. Influence du groupe aryle sur la photocyclisation d'arylcétoacétals en série hétérocyclique et osidique (1984)

Abstract La photocyclisation d'arylcétoacétals tétrahydropyranniques conduit selon une réaction de type Norrish II à des composés spiranniques. En série acétalique dihydropyrannique, cette réaction entre en compétition avec la réaction de Paterno‐Buchi. En série osidique, la réaction n'est plus stéréosélective comme dans le cas de dérivés méthylés précédemment étudiés; cependant, l'abaissement de la température ralentit Pinterconversion du radical cétalique et conduit principalement aux produits d'hétérocyclisation avec rétention de configuration. Par ailleurs, l'épimérisation acide des spiro C‐1 sucres donne les dérivés trans α ou β.
Recent Studies on Buckling of Carbon Nanotubes (2010)

This paper reviews recent research studies on the buckling of carbon nanotubes. The structure and properties of carbon nanotubes are introduced to the readers. The various buckling behaviors exhibited by carbon nanotubes are also presented herein. The main factors, such as dimensions, boundary conditions, temperature, strain rate, and chirality, influencing the buckling behaviors are also discussed, as well as a brief introduction of the two most used methods for analyzing carbon nanotubes, i.e., continuum models and atomistic simulations. Summary and recommendations for future research are also given. Finally, a large body of papers is given in the reference section. It is hoped that this paper provides current knowledge on the buckling of carbon nanotubes, reviews the computational methods for determining the buckling loads, and inspires researchers to further investigate the buckling properties of carbon nanotubes for practical applications.
Through Silicon Via and 3-D Wafer/Chip Stacking Technology (2006)

Through silicon via and 3D wafer/chip stacking technology is thought to be the essential technology of the next generation high-end semiconductors such as high-speed microprocessors and high-speed memories. However, there are many issues regarding LSI design, process integration, thermal management, and cost are under development. Cost is one of the most critical issues to apply this technology to products. We propose to categorize the through via application into three areas, i.e. low-end, middle range and high-end. High-end area that covers fast MPUs and fast memories need very small through vias to realize high-speed signal transmission between devices. Low-end area that covers image sensors, stacked memories and discrete does not always need high-speed signal transmission, but they need ultimate low cost. Thus, we developed novel through via fabrication technology employing printed circuit board (PCB) fabrication processes. The technology was applied to a CMOS image sensor wafer and successfully demonstrated
Removal of acetaldehyde from saliva by a slow‐release buccal tablet of L‐cysteine (2001)

High alcohol intake is an independent risk factor for upper gastrointestinal (GI)-tract cancers. There is increasing evidence that acetaldehyde, the first metabolite of ethanol, might be responsible for ethanol-associated carcinogenesis. Especially among Asian heavy drinkers with the ALDH2-deficiency gene, i.e., a genetic inability to remove acetaldehyde, the risk of digestive tract cancers is markedly increased. Local acetaldehyde production from ethanol either by oral microbes, mucosal cells or salivary glands is a plausible carcinogenic agent in the saliva. The aim of our study was to examine whether is it possible to bind carcinogenic acetaldehyde from saliva with L-cysteine, which is slowly released from a special buccal tablet. Nine healthy male volunteers took part in our study, and each subject served as his own control. A placebo or L-cysteine-containing tablet was fastened under the upper lip. Thereafter the volunteers ingested 0.8 g/kg of body weight of 10% (v/v) ethanol, and saliva samples were collected at 20 min intervals for 320 min. Salivary acetaldehyde and ethanol levels were analysed by headspace gas chromatography. The mean reduction of acetaldehyde concentration of the saliva with the L-cysteine tablet compared to placebo was 59% (CL(95%) 43%, 76%). Area under the curve (AUC(0-320min)) with the L-cysteine and placebo tablet were 54.3 +/- 11 microM x hr and 162 +/- 34.2 microM x hr (mean +/- SEM), respectively (p = 0.003). After alcohol intake, up to two-thirds of carcinogenic acetaldehyde can be removed from saliva with a slow-releasing buccal L-cysteine drug formulation. Thus, a buccal cysteine tablet could potentially be used to prevent upper GI-tract cancers, especially among high-risk individuals.
Biodegradable polymer microspheres as vaccine adjuvants and delivery systems. (1998)

Though vaccination has been the most cost-effective way of controlling infectious diseases, the logistics of delivering at least two to three doses of conventional vaccines for primary immunization to achieve protection are difficult and compliance is frequently inadequate, particularly in developing countries. In recent years biodegradable polymer microspheres have received much attention for the purposes of controlled release of antigens, (i) to reduce the number of doses needed for primary immunization to as few as a single dose and (ii) to target an antigen to microfold cells on mucosal surfaces after oral administration or to antigen-presenting cells after parenteral inoculations. A variety of vaccine antigens have been encapsulated in microspheres usually composed of poly (lactic/glycolic) acid (PLGA). Based on the size of the microspheres, molecular weight of polymer and ratio of lactic to glycolic acid in the polymer, the antigen may be targeted to various cells of the immune system or it may form a depot at the site of injection, allowing the slow release of the antigen for extended periods. Additionally, another adjuvant may be incorporated inside microspheres together with the antigen, further enhancing or modulating the immune response to the desired type. The major problems in developing controlled-release vaccines include instability of vaccine antigens during micro-encapsulation, storage and subsequent hydration. We encapsulated tetanus toxoid (TT) and Haemophilus influenzae type b capsular polysaccharide conjugated to TT (Hib-T) inside PLGA microspheres and evaluated the antibody levels in mice. A single injection of these micro-encapsulated vaccines elicited high antibody levels which persisted for several months. The antibody levels were similar or superior to those elicited by conventional formulations of AIPO4-adsorbed TT or soluble Hib-T conjugate vaccine.
Enhanced antitumor activity of anti-epidermal growth factor receptor monoclonal antibody IMC-C225 in combination with irinotecan (CPT-11) against human colorectal tumor xenografts. (2002)

Colon carcinomas frequently express the epidermal growth factor receptor (EGFR), and this expression correlates with more aggressive disease and poor prognosis. Previous studies have shown that EGFR blockade by monoclonal antibody IMC-C225 can inhibit the growth of human colon carcinoma tumor cells in vitro and xenografts of these tumors in athymic mice. In this report, we have studied the in vivo activity of IMC-C225 combined with the topoisomerase I inhibitor irinotecan (CPT-11) using two models of human colorectal carcinoma in nude mice. IMC-C225 was tested at a dose of 1 or 0.5 mg administered q3d. CPT-11 was administered at a dose of 100 mg/kg/week or a maximum tolerated dose of 150 mg/kg/week. Treatment with the combination of IMC-C225 (1 and 0.5 mg) and CPT-11 (100 mg/kg) significantly inhibited the growth of established DLD-1 and HT-29 tumors compared with either CPT-11 or IMC-C225 monotherapy (P < 0.05). Combination therapy with IMC-C225 (1 mg) and the MTD of CPT-11 (150 mg/kg) resulted in a regression rate of 100 and 60% of established DLD-1 and HT-29 tumors, respectively. In a refractory tumor model, combined treatment with IMC-C225 and CPT-11 significantly inhibited the growth of CPT-11 refractory DLD-1 and HT-29 tumors, whereas either agent alone did not control tumor growth. Histological examination of treated tumors showed extensive tumor necrosis, decreased tumor cell proliferation, increased tumor cell apoptosis, and a marked decrease in tumor vasculature. These results suggest that EGFR blockade by IMC-C225 combined with topoisomerase I inhibitors may be an effective therapy against chemorefractory colorectal carcinoma tumors.

Mouse models of nonalcoholic steatohepatitis in preclinical drug development (2017)

Nonalcoholic fatty liver disease (NAFLD) has become the most common cause of chronic liver disease in the Western world. NAFLD is a complex spectrum of liver diseases ranging from benign hepatic steatosis to its more aggressive necroinflammatory manifestation, nonalcoholic steatohepatitis (NASH). NASH pathogenesis is multifactorial and risk factors are almost identical to those of the metabolic syndrome. This has prompted substantial efforts to identify novel drug therapies for correcting underlying metabolic deficits, and to prevent or alleviate hepatic fibrosis in NASH. Available mouse models of NASH address different aspects of the disease, have varying clinical translatability, and, therefore, also show different utility in drug discovery.
Heat Inactivation of Hepatitis A Virus and a Norovirus Surrogate in Soft-Shell Clams (Mya arenaria) (2010)

The effectiveness of different thermal treatments for inactivating two viruses in clams was evaluated. Soft-shell clam digestive glands experimentally contaminated with hepatitis A virus (HAV) or murine norovirus (MNV) were heated for 90, 180, or 300 seconds at 85°C or 90°C in glass vials or plastic bags with 200 g of soft-shell clam meat. Inactivation was measured by plaque assay and real-time reverse-transcription (RT)-polymerase chain reaction assay. Measured inactivation was similar using both assays. The 90°C for 90 seconds treatment reduced MNV-1 titer by 3.33 log cycles and HAV by 2.66 log cycles. At 90°C for 180 seconds, both MNV-1 and HAV were completely inactivated (titer reduced by 5.47 log cycles) in glass vials. In the presence of clam meat as well, HAV inactivation was complete at 90°C for 180 seconds. In general, HAV was more resistant to heat treatment than MNV-1, suggesting that it would require a more severe treatment than human norovirus for inactivation in soft-shell clams. The results of the present study should contribute to the development of strategies for controlling the spread of enteric viral illness via shellfish.
