BIOSURFACTANT - PRODUCING BACTE- RIA FOUND IN CONTAMINATED AND UNCONTAMINATED SOILS (2000)

Key words: surfactant, biosurfactant, Bacillus, and Pseudomonas Microbially produced surfactants have been studied for microbially enhanced oil recovery (MEOR) and the bioremediation of hydrocarbons. However, most of these studies have used biosurfactants produced by one of a small number of pure-culture microbes isolated in a laboratory. In previous work, we determined that biosurfactant-producing microorganisms were naturally present at two hydrocarbon-impacted sites. In this study, we examine the prevalence of biosurfactant producers in uncontaminated soils. Biosurfactant-producing bacteria were found to constitute a significant proportion (up to 35%) of aerobic heterotrophs. Biosurfactant producers were isolated. Isolates were identified primarily as strains of Bacillus and Pseudomonas.
Application of small interfering RNAs modified by unlocked nucleic acid (UNA) to inhibit the heart‐pathogenic coxsackievirus B3 (2009)

This study describes the first application of unlocked nucleic acid (UNA)‐modified small interfering RNAs (siRNAs) directed against a medically relevant target, the coxsackievirus B3. We systematically analyzed the impact of different siRNA modification patterns and observed good compatibility of the introduction of UNA with the maintenance of high antiviral activity. Additionally, the polarity of an siRNA was successfully reversed by modulating the relative stability of the termini with locked nucleic acid (LNA) and UNA as shown in a reporter assay. The potency of the reversed siRNA against the full‐length target was, however, too low to inhibit the infectious virus. Altogether, combined modification of siRNAs with LNA und UNA provides a promising approach to alter and improve properties of an siRNA.
High mobility top-gated pentacene thin-film transistors (2005)

A common device geometry for measuring the electrical characteristics of organic semiconductors is the thin-film organic field-effect transistor (OTFT). Mostly for reasons of cost, convenience, and availability, this usually involves depositing the organic material on a prefabricated gate structure such as Si∕SiO2, the surface chemistry of which is often modified with self-assembled monolayers. The interactions between these surfaces and the deposited organic can have a profound effect on thin-film growth and the resulting electrical characteristics since most of the charge transport in these structures occurs near the organic-insulator interface. An alternative to this traditional technique is to assemble the transistor on top of the organic semiconductor. We have used chemical-vapor deposition of the polymeric dielectric material parylene to create pentacene OTFTs with gate electrodes both on top of and below the semiconductor film, with field-effect mobilities as high as 0.1cm2∕Vs and Ion∕Ioff ratios greater than 106 in the top-gated OTFTs. Comparing the electronic properties of top- and bottom-gate structures yields insight into the charge transport characteristics as well as the effects of device geometry, contacts, and surface roughness of the organic thin film.
Making Image More Energy Efficient for OLED Smart Devices (2016)

Now, more and more mobile smart devices are emerging massively; energy consumption of these devices has become an important consideration due to the limitation of battery capacity. Displays are the dominant energy consuming component of battery-operated devices, giving rise to organic light-emitting diode (OLED) as a new promising display technology, which consumes different power when displaying different content due to their emissive nature. Based on this property, we propose an approach to improve image energy efficiency on OLED displays by perceiving image content. The key idea of our approach is to eliminate undesired details while preserving the region of interest of the image by leveraging the color and spatial information. First, we use edge detection algorithm to extract region of interest (ROI) of an image. Next, we gradually change luminance and saturation of region of noninterest (NON-ROI) of the image. Then we perform detailed experiment and case study to validate our approach; experiment results show that our approach can save 22.5% energy on average while preserving high quality of the image.
Least-squares joint imaging of multiples and primaries (2005)

Abstract Multiple reflections contain subsurface reflectivity information which often complements that found in primary reflections. Previous attempts to combine the additional information by summing prestack images of the primaries and multiples have generally failed because of crosstalk leakage between the images. We present a general linear least-squares joint imaging of multiples-and primaries (LSJIMP) inversion method to simultaneously suppress crosstalk noise and combine pegleg multiples and primaries in a prestack sense. In general, LSJIMP is compatible with a wide variety of prestack imaging methods and can be extended to jointly image primaries and other embedded wave modes such as shear-wave conversions. We present a particular LSJIMP implementation that utilizes an efficient linear operator to model and image pegleg multiples in a true relative-amplitude sense. Applied to a given type of pegleg multiple in the data, our imaging operator produces an image directly comparable to primaries after NMO. Our operator's kinematic component is an extension of the NMO equation that independently images split peglegs in a moderately heterogeneous earth. Its amplitude component corrects multiples for their differences in angle-dependent reflection strength and illumination, relative to a primary. We test our LSJIMP implementation on 2D and 3D prestack field data examples and show that the method cleanly separates primaries and multiples and also uses joint information in the events to interpolate the signal in acquisition gaps.
Expression of mutant alpha-synuclein causes increased susceptibility to dopamine toxicity (2000)

Mutations of the alpha-synuclein gene have been identified in autosomal dominant Parkinson's disease (PD). Transgenic mice overexpressing wild-type human alpha-synuclein develop motor impairments, intraneuronal inclusions and loss of dopaminergic terminals in the striatum. To study the mechanism of action through which mutant alpha-synuclein toxicity is mediated, we have generated stable, inducible cell models expressing wild-type or PD-associated mutant (G209A) alpha-synuclein in human-derived HEK293 cells. Increased expression of either wild-type or mutant alpha-synuclein resulted in the formation of cytoplasmic aggregates which were associated with the vesicular (including monoaminergic) compartment. Expression of mutant alpha-synuclein induced a significant increase in sensitivity to dopamine toxicity compared with the wild-type protein expression. These results provide an explanation for the preferential dopaminergic neuronal degeneration seen in both the PD G209A mutant alpha-synuclein families and suggest that similar mechanisms may underlie or contribute to cell death in sporadic PD.
Studies with canine sera that contain antibodies which recognize human immunodeficiency virus structural proteins. (1990)

In a serological survey, using the immunoblotting technique, we found that substantial numbers of dog sera from both normal and diseased dogs, including dogs with neoplasia, reacted with one or more human immunodeficiency virus (HIV) recombinant proteins. A total of 144 dog sera were tested, and 72 (50%) of them reacted with one or more HIV recombinant structural proteins. Ten dog sera were also tested for reactivity with simian immunodeficiency virus (SIV), feline immunodeficiency virus (FIV), and caprine arthritis encephalitis virus (CAEV). Six dog sera reacted with at least the major core protein of HIV, while one of the dog sera tested reacted with SIV core protein, and there were no reactions with the viral proteins of either FIV or CAEV. Cell extracts from canine peripheral blood lymphocytes cocultivated with human cells and an extract of human cells infected with HIV were immunoblotted against dog sera which previously tested positive or negative on HIV recombinant protein commercially available Western blot strips. Two lymphocyte lysates and the HIV-infected Hut cell lysate reacted with the Western blot strip-positive dog serum; however, no reactions were seen with the Western blot strip-negative dog serum.

Obesity in long‐term survivors of childhood acute lymphoblastic leukemia (2008)

Consistent with published evidence from other regions of the developed and developing world, there is a significant prevalence of obesity in young ALL survivors in the French speaking part of Switzerland. Factors significantly associated with this late effect were mostly related to the familial background rather than to the treatment components.
Collapse of Single-Wall Carbon Nanotubes is Diameter Dependent (2004)

We present classical molecular dynamics simulations demonstrating that single-wall carbon nanotube (SWNT) bundles collapse under hydrostatic pressure. The collapse pressures obtained as a function of nanotube diameter are in excellent quantitative agreement with new data presented here for small diameter (d approximately 0.8 nm) SWNTs, and the majority of previously published results, although there remain some unreconciled contradictions in the literature. The collapse pressure is found to be independent of the nanotube chirality, and a lower limit on the largest SWNT that remains inflated at atmospheric pressure is established (d>4.16 nm).
Searching Drug-Like Anti-cancer Compound(s) Based on G-Quadruplex Ligands (2012)

G-quadruplex structure is a four-stranded form of DNA, which is associated with cancer cell proliferation. G-quadruplex-stabilized ligands have the potential to interfere with telomere replication by blocking the elongation procedure catalyzed by telomerase, and therefore have the potential to be anti-cancer drugs. A considerable number of novel compounds capable of targeting G-quadruplex at high affinity and specificity have been reported. Among them, several G-quadruplex ligands have shown promising anti-cancer activity in tumor xenograft models, and entered phase II clinical trials on cancer patients. This review summarized recent developments of G-quadruplex ligands as anti-cancer drugs and several powerful strategies to discover novel G-quadruplex ligands as anti-cancer drug candidates by screening natural product extracts and structural optimization of previously identified typical compounds.

Molecular orientation in polymers from near-field optical polarization measurements (1996)

A combined noncontact shear force and scanning near-field optical microscope has been used to study the structure of a spherulitic polyhydroxybutyrate specimen. Using polarized light, the birefringence structure of the spherulite revealed a concentric ring structure with submicron resolution. Optical images could be correlated with the topographic images, recorded simultaneously, of the same area. This demonstrated directly the correlation between the twisting structure of the ribbonlike polymer crystallites and the birefringent concentric ring structure, and demonstrates the capability of scanning near-field optical microscopy for studying molecular orientation as a function of topographic structure.
MEL‐type Pure‐Silica Zeolite Nanocrystals Prepared by an Evaporation‐Assisted Two‐Stage Synthesis Method as Ultra‐Low‐<i>k</i> Materials (2008)

Abstract A MEL‐type pure‐silica zeolite (PSZ), prepared by spin‐on of nanoparticle suspensions, has been shown to be a promising ultra‐low‐dielectric‐constant ( k ) material because of its high mechanical strength, hydrophobicity, and chemical stability. In our previous works, a two‐stage synthesis method was used to synthesize a MEL‐zeolite nanoparticle suspension, in which both nanocrystal yield and particle size of the zeolite suspension increased with increasing synthesis time. For instance, at a crystal yield of 63%, the particle size is 80 nm, which has proved to be too large because it introduces a number of problems for the spin‐on films, including large surface roughness, surface striations, and large mesopores. In the current study, the two‐stage synthesis method is modified into an evaporation‐assisted two‐stage method by adding a solvent‐evaporation process between the two thermal‐treatment steps. The modified method can yield much smaller particle sizes (e.g., 14 vs. 80 nm) while maintaining the same nanocrystal yields as the two‐stage synthesis. Furthermore, the nanoparticle suspensions from the evaporation‐assisted two‐stage synthesis show a bimodal particle size distribution. The primary nanoparticles are around 14 nm in size and are stable in the final suspension with 60% solvent evaporation. The factors that affect nanocrystal synthesis are discussed, including the concentration, pH value, and viscosity. Spin‐on films prepared by using suspensions synthesized this way have no striations and improved elastic modulus (9.67 ± 1.48 GPa vs. 7.82 ± 1.30 GPa), as well as a similar k value (1.91 ± 0.09 vs. 1.89 ± 0.08) to the previous two‐stage synthesized films.
Charakterisierung von disperisionen durch gekopplete H<sub>2</sub>O/D<sub>2</sub>O‐ultrazentrifugenmessungen (1984)

Abstract The particle size distribution is one of the most important characteristics of aqueous polymer dispersions (diameter range 20 < D < 2000 nm). In addtion, the knowledge of the average particle density ρ PM , the density distribution, and the particle refractive index n PM gives information about the chemical composition of dispersions. We report of an ultracentrifuge method which allows to determine all these values simultaneously in one single run. For that purpose the dispersion is measured simultaneously in 3 media of different density, i.e., in H 2 O, H 2 O/D 2 O (1:1, by wt.), and D 2 O. We use a preparative ultracentrifuge with an analystical rotor with trubidity optics, but instead of an 1‐cell‐rotor an 8‐cells‐rotor and a multiplexer are used. In order to measure very small and very large particles simultaneously in one single run we do not work at the usual constant number of rotor revolutions, but at a rate of revolutions increasing from 0 to 40000 min −1 . The ultracentrifuge is connected with a computer on‐line. The calculations are based on Stokes' law and Mie's light scattering theory for homogeneous isotropic spherical particles.
Cyclic redundancy checking by program (1971)

Recent advances in the use of mini-computers as control elements of a computer complex and as intelligent terminals are indicative of a trend toward relocation of certain hardware functions to micro-program or machine level program. One such function which is a particularly good candidate, for various reasons, has already been moved into program in several machines (e.g., IBM System 360/25 Integrated Communication Adapter and the IBM 1130). This function is error control using an error detection Cyclic Redundancy Check (CRC). A CRC is a variable length shortened cyclic code in which a message is a code word if, and only if, the message polynomial M (x) is divisible by the generator polynomial G(x).
Decreased Inositol 1,4,5-Trisphosphate Content in Pathogen-Challenged Soybean Cells (2000)

Phosphoinositide-specific phospholipase C (PI-PLC) has been shown to be transiently activated when plant cells were treated with elicitors. We thus investigated the activity of PI-PLC when soybean cells were infected with the bacterial pathogen Pseudomonas syringae pv. glycinea, by measuring cellular cytosolic inositol 1,4,5-trisphosphate (IP3) levels. We observed that IP3 content decreased in both compatible and incompatible interactions. In vitro phosphatase activities were similar in both water control and infected cells with slightly lower IP3 degradation observed for infected cells, indicating that the reduced IP3 content in infected cells most likely results from reduced PI-PLC activity. We hypothesize that reduced IP3 content following infection may lead to suppression of various housekeeping activities of the cells, thus diverting the cellular resources either to the synthesis of defense-related compounds against pathogens, and/or to the growth of pathogens.
Carrier-Based Drug Delivery System for Treatment of Acne (2014)

Approximately 95% of the population suffers at some point in their lifetime from acne vulgaris. Acne is a multifactorial disease of the pilosebaceous unit. This inflammatory skin disorder is most common in adolescents but also affects neonates, prepubescent children, and adults. Topical conventional systems are associated with various side effects. Novel drug delivery systems have been used to reduce the side effect of drugs commonly used in the topical treatment of acne. Topical treatment of acne with active pharmaceutical ingredients (API) makes direct contact with the target site before entering the systemic circulation which reduces the systemic side effect of the parenteral or oral administration of drug. The objective of the present review is to discuss the conventional delivery systems available for acne, their drawbacks, and limitations. The advantages, disadvantages, and outcome of using various carrier-based delivery systems like liposomes, niosomes, solid lipid nanoparticles, and so forth, are explained. This paper emphasizes approaches to overcome the drawbacks and limitations associated with the conventional system and the advances and application that are poised to further enhance the efficacy of topical acne formulations, offering the possibility of simplified dosing regimen that may improve treatment outcomes using novel delivery system.

Neighbor risk reporting in vehicular networks (2017)

With the issuance of the Notice of Proposed Rule Making (NPRM) for Vehicle to Vehicle (V2V) communications by the United States National Highway Traffic Safety Administration (NHTSA), the goal of the widespread deployment of vehicular communications and networking has taken a significant step towards becoming a reality. As with most connected technologies, protection of privacy is an ongoing concern. In order for consumers to accept the technology, it is expected that reasonable mechanisms will be in place to protect their privacy. Cooperative Caching has been proposed as an approach that can be used to improve privacy by distributing and caching data items throughout the mobile network as they are requested. When a device requires a data item, it will first query other devices for the data item before querying a centralized server. The privacy improvement is achieved by alleviating the need to send all requests to a centralized location that may be vulnerable to an attack. However, with this approach, the requesting device exposes itself to one or more generally unknown devices in the network as part of the data discovery process. This presents another privacy concern in the sense that these devices may expose information related to the request. In this paper we present a novel Cooperative Caching system in support of non-safety based applications (such as the many location based services) in which devices monitor the relative risk associated with each of its neighbors. Based on this information, requesting devices select and query specific neighbors that present little risk while avoiding neighbors that might present higher risk. We have conducted a preliminary performance evaluation of our approach that demonstrates a significant reduction in the overall risk of exposure when compared with simply broadcasting the request to all neighbors.
