Beneficial effects of SR33805 in failing myocardium (2011)

The present study indicates that treatment with SR33805 improved contractility of ischaemic failing hearts after MI in the rat by selectively modulating the phosphorylation status of sarcomeric regulatory proteins, which then sensitized the myofilaments to Ca(2+). Our results gave a proof of concept that manipulation of the Ca(2+) sensitivity of sarcomeric regulatory proteins can be used to improve contractility of a failing heart.
Effect of sp2 species in a boron-doped diamond electrode on the electrochemical reduction of CO2 (2020)

The effect of sp2 carbon within a boron-doped diamond (BDD) electrode on the electrochemical reduction of CO2 is investigated for the first time. With increasing sp2 content, the Faradaic efficiency for the production of hydrogen (H2) under constant current density increases while that for the production of formic acid (HCOOH) decreases. Moreover, favorable electrolysis conditions for producing HCOOH shift in the negative potential direction with increasing sp2 content. This phenomenon is ascribed to the presence of adsorption sites on the sp2 carbon. This work provides guidance for selectively controlling the reduction of CO2 by adjusting the distribution of carbonaceous species in the BDD electrode.
Fog Orchestration for Internet of Things Services (2017)

Large-scale Internet of Things (IoT) services such as healthcare, smart cities, and marine monitoring are pervasive in cyber-physical environments strongly supported by Internet technologies and fog computing. Complex IoT services are increasingly composed of sensors, devices, and compute resources within fog computing infrastructures. The orchestration of such applications can be leveraged to alleviate the difficulties of maintenance and enhance data security and system reliability. However, efficiently dealing with dynamic variations and transient operational behavior is a crucial challenge within the context of choreographing complex services. Furthermore, with the rapid increase of the scale of IoT deployments, the heterogeneity, dynamicity, and uncertainty within fog environments and increased computational complexity further aggravate this challenge. This article gives an overview of the core issues, challenges, and future research directions in fog-enabled orchestration for IoT services. Additionally, it presents early experiences of an orchestration scenario, demonstrating the feasibility and initial results of using a distributed genetic algorithm in this context.
Ubiquinone biosynthesis in microorganisms (2001)

The quinoid nucleus of the benzoquinone, ubiquinone (coenzyme Q; Q), is derived from the shikimate pathway in bacteria and eukaryotic microorganisms. Ubiquinone is not considered a vitamin since mammals synthesize it from the essential amino acid tyrosine. Escherichia coli and other Gram-negative bacteria derive the 4-hydroxybenzoate required for the biosynthesis of Q directly from chorismate. The yeast, Saccharomyces cerevisiae, can either form 4-hydroxybenzoate from chorismate or tyrosine. However, unlike mammals, S. cerevisiae synthesizes tyrosine in vivo by the shikimate pathway. While the reactions of the pathway leading from 4-hydroxybenzoate to Q are the same in both organisms the order in which they occur differs. The 4-hydroxybenzoate undergoes a prenylation, a decarboxylation and three hydroxylations alternating with three methylation reactions, resulting in the formation of Q. The methyl groups for the methylation reactions are derived from S-adenosylmethionine. While the prenyl side chain is formed by the 2-C-methyl-D-erythritol 4-phosphate (non-mevalonate) pathway in E. coli, it is formed by the mevalonate pathway in the yeast.
Over-expression of BCAT1, a c-Myc target gene, induces cell proliferation, migration and invasion in nasopharyngeal carcinoma (2013)

Our study indicates that gene amplification and c-Myc up-regulation are responsible for BCAT1 overexpression in primary NPC, and overexpression of BCAT1 induces cell proliferation, migration and invasion. The results suggest that BCAT1 may be a novel molecular target for the diagnosis and treatment of NPC.
A short note a small virtually-addressed control blocks (1995)

Being able to access task and thread control blocks in the virtual address space has some structuring and performance advantages, but using one page per control block is too expensive in some cases. This paper describes how to emulate smaller kernel pages though still using the hardware MMU.

[Beneficial effect of a selective TXA2 synthetase inhibitor, OKY-046, both on thromboxane B2 production and vascular damage after spinal cord injury in rat spinal cord]. (1990)

Thromboxane A2 (TXA2) is an eicosanoid with potent platelet aggregation and vasoconstricting activity, while prostaglandin I2 (PGI2) antagonizes its activity. But these eicosanoids are so labile that the stable degradation products, thromboxane B2 (TXB2) and 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha), are determined in biological materials. In a rat spinal cord compression injury model, a production of TXB2 reached a peak (133.6 +/- 13.8 pmol/g cord) 5 minutes after compression injury, while that of 6-keto-PGF1 alpha slightly increased (26.2 +/- 11.7 pmol/g cord). And the magnitude of the increase in TXB2 and the extent of post-traumatic vascular damage as determined by fluorescein uptake were both dependent on the degree of spinal cord compression injury. We also studied the effect of a selective TXA2 synthetase inhibitor, OKY-046 [E)-3-[4-(1-imidazolylmethyl)phenyl]-2-propenoic acid), both on TXB2 production in the injured spinal cord and post-traumatic vascular damage. When OKY-046 was administered intravenously 10 minutes prior to compression injury at a dose of 500 micrograms/kg body weight, the increased production of TXB2 was inhibited by about 80% and uptake of sodium fluorescein was reduced by a maximum of 40%. When the compression injury was induced before OKY-046 was administered, the inhibitory effect of OKY-046 on TXB2 production decreased depending on the duration before administration. In contrast, the 6-keto-PGF1 alpha level was not affected in the presence of OKY-046.
A fast multichannel fluorometer for investigating aquatic chemoreception and odor trails (1988)

An instrument used in measuring the dispersal of fluorescent dye as a tracer of semiochemicals in an aquatic environment allows measurements of chemical gradients to be made over distances naturally separating the bilateral olfactory appendages of small benthic organisms. Its four probes consist of two optical fibers each: one fiber conducts light of excitation wavelengths to illuminate an indicator dye; the other transmits fluorescent emissions from the dye to photodetectors. Sampling is at intervals as short as 10 ms, which approaches the latencies of animal olfactory and taste receptors. The volume sampled by each probe is presently undefined although measurement of dye concentration is attenuated about 10‐fold within 1 cm distant of a probe tip, i.e. within the range sampled by olfactory organs of small aquatic animals. The device uses neither flow cells nor pumping, and it is able to record stable measurements of fluorescent dye in sunlight and in darkness. Initial field measurements affirm that chemo‐orientation by a small aquatic animal is feasible, but it would probably use phase offset in paired sensors and thus require short‐term memory.
Corneal Safety of Topically Applied Naltrexone (2006)

Topical application of NTX over a 10,000-fold range of dosage had no overt toxicity for the parameters studied, indicating that efficacy studies for the use of NTX in corneal wound healing are warranted.
FimA, a major virulence factor associated with Streptococcus parasanguis endocarditis (1995)

Adherence of microorganisms to damaged heart tissue is a crucial event in the pathogenesis of infective endocarditis. In the present study, we investigated the role of the FimA protein as a potential virulence factor associated with Streptococcus parasanguis endocarditis. FimA is a 36-kDa surface protein that is a recognized adhesin in the oral cavity where it mediates adherence to the salivary pellicle. An insertion mutant and a deletion mutant of S. parasanguis were employed in the rat model of endocarditis to determine the relevance of FimA in endocarditis pathogenesis. Catheterized rats were infected with either the fimA deletion mutant VT929, the fimA insertion mutant VT930, or the isogenic, wild-type S. parasanguis FW213. Rats inoculated with FW213 developed endocarditis more frequently (50.9%) than animals inoculated with either the deletion mutant (2.7%) or the insertion mutant (7.6%) (P < 0.001). A series of in vitro assays were performed to explore the mechanism(s) by which FimA enhanced the infectivity of S. parasanguis. FimA did not inhibit the uptake or the subsequent killing of S. parasanguis by phagocytic granulocytes. Similarly, FimA did not play a role in the adherence to or the aggregation of platelets. Significant differences were noted between FW213 and VT929 (P < 0.05) and FW213 and VT930 (P < 0.001) in their abilities to bind to fibrin monolayers. The mean percent adherence of FW213 to fibrin monolayers (2.1%) was greater than those of VT929 (0.5%) and VT930 (0.12%). Taken together, these results indicate that FimA is a major virulence determinant associated with S. parasanguis endocarditis and further suggest that its role is associated with initial colonization of damaged heart tissue.
CRTH2 antagonism significantly ameliorates airway hyperreactivity and downregulates inflammation-induced genes in a mouse model of airway inflammation (2008)

Prostaglandin D 2 , the ligand for the G protein-coupled receptors DP1 and CRTH2, has been implicated in the pathogenesis of the allergic response in diseases such as asthma, rhinitis, and atopic dermatitis. This prostanoid also fulfills a number of physiological, anti-inflammatory roles through its receptor DP1. We investigated the role of PGD 2 and CRTH2 in allergic pulmonary inflammation by using a highly potent and specific antagonist of CRTH2. Administration of this antagonist ameliorated inflammation caused by either acute or subchronic sensitization using the cockroach egg antigen. Gene expression and ELISA analysis revealed that there was reduced proinflammatory cytokine mRNA or protein produced, as well as a wide array of genes associated with the Th2-type proinflammatory response. Importantly, the CRTH2 antagonist reduced antigen-specific IgE, IgG1, and IgG2a antibody levels as well as decreased mucus deposition and leukocyte infiltration in the large airways. Collectively, these findings suggest that the PGD 2 -CRTH2 activation axis has a pivotal role in mediating the inflammation and the underlying immune response in a T cell-driven model of allergic airway inflammation.

This paper presents an integrated tunable bandpass filter with RF MEMS varactors fabricated using the TSMC 0.35 μm CMOS process. A maskless post-processing technique is developed which enables the fabrication of RF MEMS parallel-plate capacitors with a high quality factor and a very compact size. A 2-pole coupled line tunable bandpass filter with a center frequency of 9.5 GHz and a 9% relative bandwidth is designed, fabricated and tested. A tuning range of 17% is achieved using integrated variable MEMS capacitors with a quality factor exceeding 20. The filter has an insertion loss of 5.66 dB and occupies a chip area of 1.2 × 2.1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Colonic infections (1991)

Recent significant advances in the understanding of colonic infections have occurred, particularly with regard to hemorrhagic colitis, enterohemorrhagic Escherichia coli (EHEC) infection, shigella pathogenesis, and Clostridium difficile infection.
Synthetic-aperture imaging from high-Doppler-resolution measurements (2004)

We develop the theory of radar imaging from data measured by a moving antenna emitting a single-frequency waveform. We show that, under a linearized (Born) scattering model, the signal at a given Doppler shift is due to a superposition of returns from stationary scatterers on a cone whose axis is the flight velocity vector. This cone reduces to a hyperbola when the scatterers are known to lie on a planar surface. In this case, reconstruction of the scatterer locations can be accomplished by a tomographic inversion in which the scattering density function is reconstructed from its integrals over hyperbolas. We give an approximate reconstruction formula and analyse the resolution of the resulting image. We provide a numerical shortcut and show results of numerical tests in a simple case.
Nature and Appearance of Protein Digestion Products in Upper Mesenteric Blood (1959)

Dogs prepared with catheters in the superior mesenteric vein were fed meals of liver and homologous plasma protein. Analysis of the superior mesenteric blood plasma showed marked rises in amino acids up to 6 hours later. Digestion of the homologous plasma protein took essentially the same course as that of liver protein, contrary to results reported by others(7). No peptides were found and both proteins were apparently completely degraded to amino acids. Rises in lymph amino acids were qualitatively similar to those of the mesenteric plasma, though not as marked. An amino acid conjugate was isolated from all plasma samples, and its amino acid composition was determined. Its changing structure, and failure to respond in an obvious way to the meals leads us to believe that it is not of direct dietary origin.
10‐Channel Mode (de)multiplexer with Dual Polarizations (2017)

Abstract A dual‐polarization 10‐channel mode (de)multiplexer is proposed and realized with cascaded dual‐core adiabatic tapers on a silicon‐on‐insulator (SOI) platform. The mode demultiplexer has a 2.3 μm‐wide multimode bus waveguide, which supports six mode‐channels of TE polarization and four mode‐channels of TM polarization. These ten mode‐channels are (de)multiplexed with five cascaded dual‐core adiabatic tapers based on SOI nanowires. The widths for these dual‐cores are chosen optimally according to the dispersion curves of the dual‐core SOI nanowire, so that the desired highest‐order modes of TE‐ and TM‐polarizations are extracted simultaneously. These two extracted mode‐channels are coupled very efficiently to the fundamental modes of TE‐ and TM‐polarizations (TE 0 and TM 0 ) in the narrow waveguide, respectively, which are then separated by using a polarization beam splitter based on bent directional couplers. A chip consisting of a pair of 10‐channel mode (de)multiplexers is fabricated and then tested with data transmission of 30Gbps/channel. The measurement results show that all TM‐ and TE mode‐channels have low crosstalks (–15∼–25 dB) and low excess losses (0.2∼1.8 dB) over a broad wavelength band of ∼90 nm, which makes it WDM (wavelength‐division‐multiplexing)‐compatible and thus suitable for high capacity on‐chip optical interconnects.
Microreactor Chemical Bath Deposition of Laterally Graded Cd<sub>1–<i>x</i></sub>Zn<sub><i>x</i></sub>S Thin Films: A Route to High-Throughput Optimization for Photovoltaic Buffer Layers (2013)

Cd1–xZnxS (CdZnS) is a promising replacement for the CdS buffer layers in copper indium gallium (di)selenide (CIGS) solar cells because the wider band gap of CdZnS offers improved optical transmittance of blue light. Chemical bath deposition (CBD) is the state-of-the-art deposition method for CdS and CdZnS. However, CBD of CdZnS is poorly understood, and relationships between bath composition and stoichiometry, microstructure, and optoelectronic properties of the deposited film are lacking. We introduce CBD using a continuous flow microreactor as a new technique to rapidly explore a wide variety of deposition conditions on a single substrate using spatially dependent characterization. X-ray diffraction and X-ray absorption spectroscopy indicate that the film is a mixture of nanocrystalline CdZnS and amorphous Zn(O,OH,S). Over the length of a single substrate, films showed increasing Zn:Cd ratio in the nanocrystalline phase, increasing amorphous content, and increasing quantum confinement, and resultant monotonic increase in band gap from 2.42 to 2.75 eV. Microreactor CBD (μR-CBD) enables rapid identification of CdZnS compositions that are ideal candidates for thin film photovoltaics, as well as determination of the CBD conditions required to deposit them.
Neuronal Protection in Stroke by an sLe <sup>x</sup> -Glycosylated Complement Inhibitory Protein (1999)

Glycoprotein adhesion receptors such as selectins contribute to tissue injury in stroke. Ischemic neurons strongly expressed C1q, which may target them for complement-mediated attack or C1qRp-mediated clearance. A hybrid molecule was used to simultaneously inhibit both complement activation and selectin-mediated adhesion. The extracellular domain of soluble complement receptor-1 (sCR1) was sialyl Lewis x glycosylated (sCR1sLex) to inhibit complement activation and endothelial-platelet-leukocyte interactions. sCR1 and sCR1sLex colocalized to ischemic cerebral microvessels and C1q-expressing neurons, inhibited neutrophil and platelet accumulation, and reduced cerebral infarct volumes. Additional benefit was conferred by sialyl Lewis x glycosylation of the unmodified parent sCR1 molecule.
Very Low Temperature CO Oxidation over Colloidally Deposited Gold Nanoparticles on Mg(OH)<sub>2</sub> and MgO (2010)

The colloidal deposition method was used to prepare Au/Mg(OH)(2) (0.7 wt % gold) catalysts with gold particle sizes between 1.5 to 5 nm which exhibited very high activity for CO oxidation with specific rates higher than 3.7 mol(CO) x h(-1) x g(Au)(-1) even at temperatures as low as -89 degrees C.
Dexmedetomidine and the Successful Management of Electroconvulsive Therapy Postictal Agitation (2010)

Postictal agitation after electroconvulsive therapy is a common and serious condition and when severe, requires prompt intervention to safeguard the patient and medical staff from the potential for mayhem and physical harm. We present a case report on the successful use of dexmedetomidine, an alpha2 agonist, in the postictal management of severe agitation in a 34-year-old morbidly obese woman, after prior modes of intervention had failed to deliver ideal conditions.
Lithographic Resists (2002)

Abstract An introduction to lithographic resists is presented. The principles of lithography are described and the essential attributes resist materials must possess are enumerated. The chemical and physical properties of resists of current technological importance are discussed within this framework, with an emphasis on how functional performance is related to these properties. Finally, examples are provided of how resist materials are being tailored for future lithographic imaging technologies.
Insulin-Like Growth Factor-1 Receptor Activation Inhibits Oxidized LDL-Induced Cytochrome C Release and Apoptosis via the Phosphatidylinositol 3 Kinase/Akt Signaling Pathway (2003)

Our data demonstrate that IGF-1 receptor activation inhibits oxidized LDL-induced cytochrome C release and apoptosis through the phosphatidylinositol 3-kinase/Akt signaling pathway and suggest that genetic or pharmacological activation of the IGF-1 receptor may be a useful strategy to stabilize atherosclerotic plaques.
Concentration Dependency of the Fluorescence from Solutions of 2-Phenyl Indole and Derivatives of 2-Phenyl Indole. II. uv Radiation Excitation (1968)

The fluorescence spectra and fluorescence yields were measured as a function of solute concentrations for uv excitation of 2-phenyl indole and some derivatives of 2-phenyl indole. Correlations between structure and self-quenching were similar to the correlations obtained with fast-electron excitation. The formation of excimers was demonstrated as the concentration of certain derivatives of 2-phenyl indole was increased. A common pathway of excimer formation and self-quenching was indicated from the results.
A concurrent algorithm for avoiding deadlocks in multiprocess multiple resource systems (1972)

In computer systems in which resources are allocated dynamically, algorithms must be executed whenever resources are assigned to determine if the allocation of these resources could possibly result in a deadloc_______~k; a situation in which two or more processes remain in an idle or blocked state indefinitely.
Nonadiabatic small-polaron hopping electron transport in diphenoquinone-doped polycarbonate (1991)

The dependences of electron mobility on the electric field F, temperature T, and hopping site distance R have been characterized in 3,5-dimethyl-3′,5′-di-tert-butyl-4,4′-diphenoquinone dispersed molecularly in a polycarbonate according to Schein’s analytical technique. The electron mobility can be described in the form a0R2 exp(−2R/R0) exp(−E0/kT) × exp[β(1/kT−1/kT0)F1/2], where a0, R0, β, and T0 are constants. Moreover, it is found that the zero-field activation energy E0 is independent of R. The invariable E0 and the exponential dependence of the Arrhenius prefactor on R strongly suggest that the electron transport therein is due to nonadiabatic small-polaron hopping. Based on the small-polaron theory, the transport properties are qualitatively discussed in terms of molecular properties.
