Complementary Deoxyribonucleic Acid Cloning and Tissue Expression of BSP-A3 and BSP-30-kDa: Phosphatidylcholine and Heparin-Binding Proteins of Bovine Seminal Plasma1 (1999)

BSP-A1, BSP-A2, BSP-A3, and BSP-30-kDa are four major proteins of bovine seminal plasma (BSP protein family). These heparin- and phosphatidylcholine-binding proteins potentiate the capacitation of spermatozoa. Here we determined the complete sequences of the two cDNAs coding for the BSP-A3 and BSP-30-kDa proteins. Degenerate oligonucleotides designed on the basis of the primary sequences of the proteins were used as primers in reverse transcription-polymerase chain reaction, with cDNA preparations of bovine seminal vesicles as templates, to amplify an internal fragment of each BSP cDNA. Specific oligonucleotides designed on the basis of these partial cDNA sequences were used to clone the two complete cDNAs by using the 3' rapid amplification of cDNA ends (RACE) and 5' RACE methods. We also verified the expression of all members of the bovine BSP protein family in several adult bovine tissues by RNase protection assays. The results indicated that each BSP protein mRNA is expressed only in seminal vesicles and in the ampullae. Homologous genes were detected in human, rat, hamster, and rabbit genomic DNA, using high-stringency Southern hybridization with a specific BSP-30-kDa cDNA probe.
Silver Migration in Electrical Insulation (1955)

Silver migration may be defined as a process by which silver, when in contact with insulating materials under electrical potential, is removed ionically from its initial location, and is redeposited as metal at some other location. This process requires adsorption of water on the insulation surface. Silver is unique in this respect in that it is easily oxidized and reduced and does not passivate. Other metals do not present a practical migration hazard. Presented herein are examples of actual experience wherein silver migration caused trouble, and an explanation of this phenomenon based upon chemical and physical considerations and related laboratory evidence. It is concluded that silver should be used with great caution under the conditions noted.
Electrogenerated Chemiluminescence. 81. Influence of Donor and Acceptor Substituents on the ECL of a Spirobifluorene-Bridged Bipolar System (2005)

The electrochemistry and radical ion annihilation electrogenerated chemiluminescence (ECL) of 9,9'-spirobifluorene-bridged bipolar systems containing 1,3,4-oxadiazole-conjugated oligoaryl and triarylamine substituents were investigated. The stability of the oxidized spirobifluorenes was improved by functionalization with triarylamine centers. These donor-acceptor (DA) compounds exhibited a good fluorescence efficiency with an emission maximum that correlated with the potential difference between radical anion and cation formation, suggesting a charge transfer (CT) emission band. An ECL mechanism based on the formation of the CT excited state by radical ion annihilation or production of the triplet state followed by triplet-triplet annihilation, with perhaps some excimer contribution, is proposed.
Artificial Extension of the Adenovirus Fiber Shaft Inhibits Infectivity in Coxsackievirus and Adenovirus Receptor-Positive Cell Lines (2002)

Recent studies demonstrate that virus-cellular receptor interactions are not the sole determinants of adenovirus (Ad) tropism. It has been shown that the fiber shaft length, which ranges from 6 to 23 beta-repeats in human Ads, also influences viral tropism. However, there is no report that investigates whether artificial extension of the shaft alters the infectivity profile of Ad. Therefore, we constructed Ad serotype 5 (Ad5) capsid-based longer-shafted Ad vectors by incorporating Ad2 shaft fragments of different lengths into the Ad5 shaft. We show that "longer-shafted" Ad vectors (up to 32 beta-repeats) could be rescued. We also show that longer-shafted Ad vectors had no impact on knob-CAR (coxsackievirus and Ad receptor) interaction compared to wild-type Ad. Nevertheless, gene transfer efficiencies of longer-shafted Ad vectors were lower in CAR-positive cell lines compared to wild-type Ad. We suggest that artificial extension of the shaft can inhibit infectivity in the context of CAR-positive cell lines without modification of knob-CAR interaction.
Neuron‐to‐neuron transmission of α‐synuclein fibrils through axonal transport (2012)

These results support the hypothesis that the progression of Parkinson disease can be caused by neuron-to-neuron spread of α-synuclein aggregates and that the anatomical pattern of progression of lesions between axonally connected areas results from the axonal transport of such aggregates. That the transfer did not appear to be trans-synaptic gives hope that α-synuclein fibrils could be intercepted by drugs during the extracellular phase of their journey.
<i>ent</i>-Labdane Diterpenoids from <i>Andrographis paniculata</i> (2005)

Six new ent-labdane diterpenoids, 3-O-beta-D-glucopyranosyl-14,19-dideoxyandrographolide (1), 14-deoxy-17-hydroxyandrographolide (2), 19-O-[beta-D-apiofuranosyl(1-->2)-beta-D-glucopyranoyl]-3,14-dideoxyandrographolide (3), 3-O-beta-d-glucopyranosylandrographolide (4), 12S-hydroxyandrographolide (5), and andrographatoside (6), together with 17 known analogues, were isolated from the aerial parts of Andrographis paniculata. The structures of 1-6 were determined by spectroscopic data analysis. All compounds isolated were evaluated for their inhibitory activity against several bacterial and fungal strains.
Experimental Investigation of a Flexible Bellows Heat Pipe for Cooling Discrete Heat Sources (1990)

A computer model was developed to aid in the design of a flexible bellows heat pipe for cooling small discrete heat sources or arrays of small heat sources. This model was used to evaluate the operational characteristics and performance limitations of these heat pipes and to formulate and optimize a series of conceptual designs. Three flexible bellows heat pipes approximately 40 mm in length and 6 mm in diameter were constructed and tested using three different wick configurations. The test pipes were found to be boiling limited over most of the operating temperature range tested. Heat fluxes in excess of 200 W/cm2 were obtained and thermal resistance values of less than 0.7 °C/W were measured. Although the computer model slightly underestimated the experimentally determined transport limit for one of the wicking configurations, the remaining transport predictions were consistently within 8 percent of the experimental values.

Distal tactile feedback for text entry on tabletop computers (2009)

In this paper we present an initial study into the feasibility of using a mobile phone as a personal tactile display when interacting with a tabletop computer. There has been an increase in recent years in large touchscreen computers that use soft keyboards for text input. Text entry performance on such keyboards can be poor due to the lack of tactile feedback from the keys. Our approach is to use the vibration motor in a user's mobile phone to provide personal haptic feedback for interactions with the touchscreen computer. We ran an experiment to compare text entry on a touchscreen device with the tactile feedback being presented at different distal locations on the body (locations at which a user might keep a mobile device. The conditions were: no tactile feedback, feedback directly on the device, feedback at the wrist, upper arm, chest, belt and trouser pocket). The results showed that distal tactile feedback significantly increased text entry rates when presented to the wrist and upper arm. This was not at the expense of a reduction in text entry accuracy. This shows that the concept of presenting tactile feedback on a user's phone is an effective one and can improve interaction and text entry on tabletop computers.

People count system using multi-sensing application (2002)

A people counting system with human information sensors for use in a multi-sensing application for detecting the number of persons and their directions of movement at a wide door has been developed. The sensor head module of this sensing system consists of a 1-dimensional 8-element detector array fabricated by a sheet forming method of pyroelectric PbTiO/sub 3/ ceramics, a IR-transparent lens and oscillating mechanical chopping parts. The sensor output is binarized by using the background mean method, and the number of passing persons and their directions of movement are recognized by a pattern recognition algorithm. By using this people counting system, the number of passersby at a 200 cm wide door can be detected with more than 95% accuracy.
Mitogenic Signaling via G Protein-Coupled Receptors (1996)

RECEPTORS coupled to heterotrimeric GTP-binding proteins (G proteins) comprise the largest known family of cell surface receptors and mediate cellular responses to a diverse array of signaling molecules, including peptide and glycopeptide hormones, neurotransmitters, phospholipids, odorants, and photons. The basic unit of G protein-coupled receptor (GPCR) signaling is comprised of three parts; receptor, which detects ligand in the extracellular milieu; heterotrimeric G protein, which is dissociated into active Gα-GTP and Gβγ-subunits after interaction with the liganded receptor; and effector, which interacts with dissociated Gα-GTP and Gβγ-subunits to mediate the intracellular effects of ligand binding. In a given cell type, the responsiveness to stimulus, as well as the nature of the response, is dictated by the available complement of receptor, G protein, and effector. Despite the diverse array of ligands with which they interact, GPCRs share a conserved predicted tertiary structure characterized by seven transmembrane domains joined by intracellular and extracellular loops. G protein coupling specificity is dictated by the intracellular domains, particularly the second and third intracellular loops and the Cterminal tail. Indeed, it is possible to alter the G proteincoupling specificity of GPCRs by exchanging relatively small regions within the third intracellular loop (1).
Complex modulation with a twisted-nematic liquid-crystal spatial light modulator: double-pixel approach (2003)

I modify the double-phase holographic code to implement complex modulation with a transmission twisted-nematic liquid-crystal display. This device is employed in the mostly phase configuration, for which the phase modulation is coupled with a nonconstant amplitude modulation. The modified double-phase code implements arbitrary complex modulation employing the constrained complex modulation of the display.
Towards improved migraine management: Determining potential trigger factors in individual patients (2016)

Background Certain chronic diseases such as migraine result in episodic, debilitating attacks for which neither cause nor timing is well understood. Historically, possible triggers were identified through analysis of aggregated data from populations of patients. However, triggers common in populations may not be wholly responsible for an individual's attacks. To explore this hypothesis we developed a method to identify individual 'potential trigger' profiles and analysed the degree of inter-individual variation. Methods We applied N = 1 statistical analysis to a 326-migraine-patient database from a study in which patients used paper-based diaries for 90 days to track 33 factors (potential triggers or premonitory symptoms) associated with their migraine attacks. For each patient, univariate associations between factors and migraine events were analysed using Cox proportional hazards models. Results We generated individual factor-attack association profiles for 87% of the patients. The average number of factors associated with attacks was four per patient: Factor profiles were highly individual and were unique in 85% of patients with at least one identified association. Conclusion Accurate identification of individual factor-attack profiles is a prerequisite for testing which are true triggers and for development of trigger avoidance or desensitisation strategies. Our methodology represents a necessary development toward this goal.
A time-wavelength assignment algorithm for a WDM star network (1992)

The first time-wavelength assignment algorithm for wavelength division multiplexing (WDM) star-based local and metropolitan area networks is presented. The algorithm incorporates the unique aspects of WDM communication such as a number of tunable transmitters and receivers at each concentrator, the tuning time, and a limited number of wavelengths. The transmission duration is composed of two elements: the packet transmission time, and the overhead incurred due to the tunability of the system's transmitters and receivers. For a given traffic matrix, the algorithm obtains a TDM/WDM schedule with minimal packet transmission duration, while minimizing the tuning time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Thermoplastic composite matrices with improved solvent resistance (1984)

In order to improve solvent resistance of aromatic thermoplastic polymers, ethynyl-terminated aromatic sulfone polymers (ETS), sulfone/ester polymers (SEPE) containing pendent ethynyl groups, and phenoxy resin containing pendent ethynyl groups are synthesized. Cured polysulfones and phenoxy resins containing ethynyl groups on the ends or pendent on the molecules exhibited systematic behavior in solvent resistance, film flexibility, and toughness as a function of crosslink density. The film and composite properties of a cured solvent-resistant ETS were better than those of a commercially available solvent sensitive polysulfone. The study was part of a NASA program to better understand the trade-offs between solvent resistance, processability and mechanical properties which may be useful in designing composite structures for aerospace vehicles.
Alkoxymethylenephosphonate Analogues of (Lyso)phosphatidic Acid Stimulate Signaling Networks Coupled to the LPA<sub>2</sub> Receptor (2007)

Abstract An efficient stereocontrolled synthesis afforded alkoxymethylenephosphonate (MP) analogues of lysophosphatidic acid (LPA) and phosphatidic acid (PA). The pharmacological properties of MP‐LPA and MP‐PA analogues were characterized for LPA receptor subtype‐specific agonist and antagonist activity using Ca 2+ ‐mobilization assays in RH7777 cells expressing the individual LPA 1 –LPA 3 receptors and CHO cells expressing LPA 4 . In addition, activation of a PPARγ reporter gene construct expressed in CV‐1 cells was assessed. These metabolically stabilized LPA analogues exhibited an unexpected pattern of partial agonist/antagonist activity for the LPA G‐protein‐coupled receptor family and the intracellular LPA receptor PPARγ. Analogues were compared with 18:1 LPA for activation of downstream signaling in HT‐29 colon cancer cells, which exclusively express LPA 2 , and both SKOV3 and OVCAR3 ovarian cancer cells, which express LPA 1 , LPA 2 , and LPA 3 . Unexpectedly, reverse phase protein arrays showed that four MP‐LPA and MP‐PA analogues selectively activated downstream signaling in HT‐29 cells with greater potency than LPA. In particular, the oleoyl MP‐LPA analogue strongly promoted phosphorylation and activation of AKT, MEK, and pS6 in HT‐29 cells in a concentration‐dependent manner. In contrast, the four MP‐LPA and MP‐PA analogues were equipotent with LPA for pathway activation in the SKOV3 and OVCAR3 cells. Taken together, these results suggest that the MP analogues may selectively activate signaling via the LPA 2 receptor subtype, while simultaneously suppressing signaling through the LPA 1 and LPA 3 subtypes.

Epoxy prepolymers cured with boron trifluoride‐amine complexes, 2. Polymerization mechanisms (1990)

Abstract The kinetics of the polymerization of phenoxymethyloxirane ( 6 ) initiated by the BF 3 complex of 4‐chloroaniline ( 7 ) solubilized in oligo(ethylene oxide) of molecular weight 300 (PEO) is characterized by an initial induction period, followed by a propagation step with a rate R p = k [ 6 ] · [ 7 ] 0,32 · [PEO] −0,55 . The length of the induction period decreases with [ 7 ] and increases with [PEO]. However, R p increases with [ 7 ] and decreases with [PEO]. The reaction can be explained by the activated monomer mechanism.
