Low Temperature Plasma-Enhanced Atomic Layer Deposition of Metal Oxide Thin Films (2010)

Many reported atomic layer deposition (ALD) processes are carried out at elevated temperatures (&gt;150°C), which can be problematic for temperature-sensitive substrates. Plasma-enhanced ALD routes may provide a solution, as the ALD temperature window can, in theory, be extended to lower deposition temperatures due to the reactive nature of the plasma. As such, the plasma-enhanced ALD of Al2O3, TiO2, and Ta2O5 has been investigated at 25–400°C using [Al(CH3)3], [Ti(OiPr)4], [Ti(CpMe)(OiPr)3], [TiCp*(OMe)3], and [Ta(NMe2)5] as precursors. An O2 plasma was employed as the oxygen source in each case. We have demonstrated metal oxide thin-film deposition at temperatures as low as room temperature and compared the results with corresponding thermal ALD routes to the same materials. The composition of the films was determined by Rutherford backscattering spectroscopy. Analysis of the growth per cycle data and the metal atoms deposited per cycle revealed that the growth per cycle is strongly dependent on the film density at low deposition temperatures. Comparison of these data for Al2O3 ALD processes in particular, showed that the number of Al atoms deposited per cycle was consistently high down to room temperature for the plasma-enhanced process but dropped for the thermal process at substrate temperatures lower than 250°C.
Acaricidal Activity of Clove Bud Oil Compounds againstDermatophagoides farinaeandDermatophagoides pteronyssinus(Acari:  Pyroglyphidae) (2003)

The acaricidal activity of clove (Eugenia caryophyllata) bud oil-derived eugenol and its congeners (acetyleugenol, isoeugenol, and methyleugenol) against adults of Dermatophagoides farinae and Dermatophagoides pteronyssinus was examined using direct contact application and fumigation methods and compared with those of benzyl benzoate and N,N-diethyl-m-toluamide (DEET). Responses varied according to compound, dose, and mite species. On the basis of LD(50) values, the compound most toxic to D. farinae adults was methyleugenol (0.94 microg/cm(2)) followed by isoeugenol (5.17 microg/cm(2)), eugenol (5.47 microg/cm(2)), benzyl benzoate (9.22 microg/cm(2)), and acetyleugenol (14.16 microg/cm(2)). Very low activity was observed with DEET (37.59 microg/cm(2)). Against D. pteronyssinus adults, methyleugenol (0.67 microg/cm(2)) was much more effective than isoeugenol (1.55 microg/cm(2)), eugenol (3.71 microg/cm(2)), acetyleugenol (5.41 microg/cm(2)), and benzyl benzoate (6.59 microg/cm(2)). DEET (17.85 microg/cm(2)) was least toxic. These results indicate that the lipophilicity of the four phenylpropenes plays a crucial role in dust mite toxicity. The typical poisoning symptom of eugenol and its congeners was a similar death symptom of the forelegs extended forward together, leading to death without knockdown, whereas benzyl benzoate and DEET caused death following uncoordinated behavior. In a fumigation test with both mite species, all four phenylpropenes were much more effective in closed containers than in open ones, indicating that the mode of delivery of these compounds was largely due to action in the vapor phase. Eugenol and its congeners merit further study as potential house dust mite control agents or as lead compounds.
Structure of Peptides Investigated by Nanopore Analysis (2004)

Bacterial α-hemolysin forms a pore in a lipid membrane with well-behaved single-channel conductance so that the transit of single molecules can be studied. Here we demonstrate that the structure of individual peptides can be analyzed. Peptides were synthesized containing repeats of the sequence (Gly−Pro−Pro), which exist as mixtures of single, double, or collagen-like triple helices. The structure of individual peptides could be identified as they traverse the pore based on signature transit times and blockage currents.
Dissection of the LXXLL Nuclear Receptor-Coactivator Interaction Motif Using Combinatorial Peptide Libraries: Discovery of Peptide Antagonists of Estrogen Receptors α and β (1999)

Recruitment of transcriptional coactivators following ligand activation is a critical step in nuclear receptor-mediated target gene expression. Upon binding an agonist, the receptor undergoes a conformational change which facilitates the formation of a specific coactivator binding pocket within the carboxyl terminus of the receptor. This permits the alpha-helical LXXLL motif within some coactivators to interact with the nuclear receptors. Until recently, the LXXLL motif was thought to function solely as a docking module; however, it now appears that sequences flanking the core motif may play a role in determining receptor selectivity. To address this issue, we used a combinatorial phage display approach to evaluate the role of flanking sequences in influencing these interactions. We sampled more than 10(8) variations of the core LXXLL motif with estradiol-activated estrogen receptor alpha (ERalpha) as a target and found three different classes of peptides. All of these peptides interacted with ERalpha in an agonist-dependent manner and disrupted ERalpha-mediated transcriptional activity when introduced into target cells. Using a series of ERalpha-mutants, we found that these three classes of peptides showed different interaction patterns from each other, suggesting that not all LXXLL motifs are the same and that receptor binding selectivity can be achieved by altering sequences flanking the LXXLL core motif. Most notable in this regard was the discovery of a peptide which, when overexpressed in cells, selectively disrupted ERbeta- but not ERalpha-mediated reporter gene expression. This novel ERbeta-specific antagonist may be useful in identifying and characterizing the ERbeta-regulated process in estradiol-responsive cells. In conclusion, using a combinatorial approach to define cofactor-receptor interactions, we have clearly been able to demonstrate that not all LXXLL motifs are functionally equivalent, a finding which suggests that it may be possible to target receptor-LXXLL interactions to develop receptor-specific antagonists.
Catalysis of acetyl-CoA cleavage and tetrahydrosarcinapterin methylation by a carbon monoxide dehydrogenase-corrinoid enzyme complex. (1991)

An enzyme complex containing carbon monoxide dehydrogenase and a corrinoid protein has been isolated from Methanosarcina barkeri. Sodium dodecyl sulfate-gel electrophoresis revealed five polypeptides of molecular masses alpha = 19,700, beta = 84,500, gamma = 63,200, delta = 53,000, and epsilon = 51,400 Da in equimolar amounts. One mol of cobamide cofactor was found per minimal alpha beta gamma delta epsilon unit. The molecular mass of the native complex was 1,600,000 Da by high pressure liquid chromatography (HPLC) gel filtration, which suggested an alpha 6 beta 6 gamma 6 delta 6 epsilon 6 oligomeric structure. Catalysis of a reaction involving cleavage of acetyl-CoA and methylation of tetrahydrosarcinapterin was indicated by spectrophotometric analyses; a time-dependent absorption decrease in the 300-320 nm region was observed in the complete reaction mixture which contained acetyl-CoA, tetrahydrosarcinapterin, and the enzyme complex. In control samples lacking any one of the these components the absorption spectrum remained virtually unaltered. Reversed-phase HPLC analysis confirmed that tetrahydrosarcinapterin was converted to a product that co-eluted with authentic methyltetrahydrosarcinapterin. The product also exhibited the UV-visible absorption spectrum expected for methyltetrahydrosarcinapterin. Free CoA was identified as an additional product of the reaction. The carbonyl group of acetyl-CoA was oxidized to carbon dioxide. Spectral changes indicated concomitant Fe/S center reduction. Production of CoA was essentially stoichiometric with methyltetrahydrosarcinapterin formation and tetrahydrosarcinapterin consumption. Analyses during purification showed that catalytic activity was restricted exclusively to the fractions that contained the carbon monoxide dehydrogenase-corrinoid enzyme complex.
Serine threonine protein kinases of mycobacterial genus: phylogeny to function (2006)

Serine/threonine protein kinases (STPKs) are known to act as sensors of environmental signals that thereby regulate developmental changes and host pathogen interactions. In this study, we carried out comparative genome analysis of six completely sequenced pathogenic and nonpathogenic mycobacterial species to systematically characterize the STPK complement of mycobacterium. Our analysis revealed that while Mycobacterium tuberculosis strains have 11 conserved kinases, this number varies from 4 to 24 in other mycobacterial species. pknA, an essential STPK encoding gene, was found to be truncated in the initial analysis of M. avium subsp. paratuberculosis (Map) and M. tuberculosis C genomes. However, resequencing of pknA gene in Map confirmed that the truncation was due to a sequencing error. The conservation of division and cell wall gene cluster involved in cell envelope biosynthesis and cell division, in the vicinity of pknL locus, implicates a possible role of PknL in cell division and envelop biosynthesis. We identified a cyclophilin domain as part of a mycobacterial kinase in Map that suggests a plausible regulation of cyclophilins by phosphorylation. The co-inheritance of pknA, pknB, pknG, and pknL loci across genomes and some unique repertoire of pathogen-specific kinases such as pknI and pknJ of Mtb complex suggest similitude and divergence between pathogenic and nonpathogenic signaling. This study would add another dimension toward identification of physiological substrates and thereby function, while resolving the existing complexities in signaling network between the two domains of life, pathogen and nonpathogen.
Interface between Topological and Superconducting Qubits (2011)

We propose and analyze an interface between a topological qubit and a superconducting flux qubit. In our scheme, the interaction between Majorana fermions in a topological insulator is coherently controlled by a superconducting phase that depends on the quantum state of the flux qubit. A controlled-phase gate, achieved by pulsing this interaction on and off, can transfer quantum information between the topological qubit and the superconducting qubit.
Telematic Transmission of Computerized Blood Glucose Profiles for IDDM Patients (1991)

Telematic transmission of SMBG is feasible. It can improve SMBG analysis and perhaps glucose control, therefore offering a new way of communication between diabetic patients and their physicians.

High-Stearic and High-Oleic Cottonseed Oils Produced by Hairpin RNA-Mediated Post-Transcriptional Gene Silencing (2002)

We have genetically modified the fatty acid composition of cottonseed oil using the recently developed technique of hairpin RNA-mediated gene silencing to down-regulate the seed expression of two key fatty acid desaturase genes, ghSAD-1-encoding stearoyl-acyl-carrier protein Delta 9-desaturase and ghFAD2-1-encoding oleoyl-phosphatidylcholine omega 6-desaturase. Hairpin RNA-encoding gene constructs (HP) targeted against either ghSAD-1 or ghFAD2-1 were transformed into cotton (Gossypium hirsutum cv Coker 315). The resulting down-regulation of the ghSAD-1 gene substantially increased stearic acid from the normal levels of 2% to 3% up to as high as 40%, and silencing of the ghFAD2-1 gene resulted in greatly elevated oleic acid content, up to 77% compared with about 15% in seeds of untransformed plants. In addition, palmitic acid was significantly lowered in both high-stearic and high-oleic lines. Similar fatty acid composition phenotypes were also achieved by transformation with conventional antisense constructs targeted against the same genes, but at much lower frequencies than were achieved with the HP constructs. By intercrossing the high-stearic and high-oleic genotypes, it was possible to simultaneously down-regulate both ghSAD-1 and ghFAD2-1 to the same degree as observed in the individually silenced parental lines, demonstrating for the first time, to our knowledge, that duplex RNA-induced posttranslational gene silencing in independent genes can be stacked without any diminution in the degree of silencing. The silencing of ghSAD-1 and/or ghFAD2-1 to various degrees enables the development of cottonseed oils having novel combinations of palmitic, stearic, oleic, and linoleic contents that can be used in margarines and deep frying without hydrogenation and also potentially in high-value confectionery applications.
A Novel 55-kDa Regulatory Subunit for Phosphatidylinositol 3-Kinase Structurally Similar to p55PIK Is Generated by Alternative Splicing of the p85α Gene (1996)

Phosphatidylinositol 3-kinase, which is composed of a 110-kDa catalytic subunit and a regulatory subunit, plays important roles in various cellular signaling mechanisms. We screened a rat brain cDNA expression library with 32P-labeled human IRS-1 protein and cloned cDNAs that were very likely to be generated by alternative splicing of p85alpha gene products. These cDNAs were demonstrated to encode a 55-kDa protein (p55alpha) containing two SH2 domains and an inter-SH2 domain of p85alpha but neither a bcr domain nor a SH3 homology domain. Interestingly, p55 alpha contains a unique 34-amino acid sequence at its NH2 terminus, which is not included in the p85alpha amino acid sequence. This 34-amino acid portion was revealed to be comparable with p55PIK (p55gamma) in length, with a high homology between the two, suggesting that these NH2-terminal domains of p55alpha and p5 gamma may have a specific role that p85 does not. The expression of p55alpha mRNA is most abundant in the brain, but expression is ubiquitous in most rat tissues. Furthermore, it should be noted that the expression of p85alpha mRNA in muscle is almost undetectably low by Northern blotting with a cDNA probe coding for the p85alpha SH3 domain, while the expression of p55alpha can be readily detected. These results suggest that p55 alpha may play an unique regulatory role for phosphatidylinositol 3-kinase in brain and muscle.
Fast Higher Bandwidth X. (1995)

This paper proposes an X Window System protocol compression scheme called Fast Higher Bandwidth X (FHBX). Previous X protocol compression schemes were either much slower (Higher Bandwidth X) or much less effective (Xremote). By using an application specific predictive hashing technique, FHBX is able to deliver three times the compression performance of Xremote, while running ten times as fast as HBX. The family of structured compression techniques illustrated by FHBX is applicable to other structured protocols, and should enable a host of interactive applications on low bandwidth wireless devices and telephone links. 1 Introduction This research is targeted at the vast numbers of networks which are, and which will continue to be, too slow. These networks include normal telephone connections, wireless connections, internet connections, and ISDN connections. If the current rate of increase in CPU performance holds, unloaded 10Mbit/sec Ethernet connections will be candidates for softwar...
Thin film light emitting devices from an electroluminescent ruthenium complex (1996)

A ruthenium polypyridyl complex has been synthesized and examined as an emitter material in thin film electroluminescent devices. This material exhibits photoluminescent and electroluminescent effects as well as several reversible one-electron oxidation and reduction processes. Electroluminescent devices fabricated from this ruthenium complex either via spin coating methods or self-assembly techniques exhibit relatively high electroluminescent efficiencies and luminance levels in some cases as high as 100 cd/m2.
Introduction to connectionist models in cognitive psychology: Basic structures, processes, and algorithms (2004)

This book aims to present an overview of the current state of connectionist
modelling in cognitive psychology, covering a broad range of areas. All of the
authors are specialists in their chosen topic, and most have been actively
engaged in connectionist cognitive modelling for many years. In these chapters the reader will ﬁnd numerous examples of the way in which theories
implemented in the form of connectionist models have interacted, and
continue to interact, with experimental data in an intellectually productive
and stimulating way. I believe these contributions speak for themselves and
that there is no need in this introduction to advance or defend any particular
conception of the modelling enterprise. Instead, my purpose here is to provide an accessible introduction to some of the basic, and most frequently
encountered, features of connectionist cognitive modelling, ones that recur
throughout the chapters of the book. Readers new to connectionist modelling, or who encounter diﬃculty with technicalities in any of the chapters,
will hopefully ﬁnd the discussion presented here of some use.
Phase I clinical and pharmacokinetic study of PK1 [N-(2-hydroxypropyl)methacrylamide copolymer doxorubicin]: first member of a new class of chemotherapeutic agents-drug-polymer conjugates. Cancer Research Campaign Phase I/II Committee. (1999)

PK1 comprises doxorubicin covalently bound to N-(2-hydroxypropyl)methacrylamide copolymer by a peptidyl linker. Following cellular uptake via pinocytosis, the linker is cleaved by lysosomal enzymes, allowing intratumoral drug release. Radically altered plasma and tumor pharmacokinetics, compared to free doxorubicin, and significant activity in animal tumors have been demonstrated preclinically. We aimed to determine the maximum tolerated dose, toxicity profile, and pharmacokinetics of PK1 as an i.v. infusion every 3 weeks to patients with refractory or resistant cancers. Altogether, 100 cycles were administered (range, 20-320 mg/m2 doxorubicin-equivalent) to 36 patients (20 males and 16 females) with a mean age of 58.3 years (age range, 34-72 years). The maximum tolerated dose was 320 mg/m2, and the dose-limiting toxicities were febrile neutropenia and mucositis. No congestive cardiac failure was seen despite individual cumulative doses up to 1680 mg/m2. Other anthracycline-like toxicities were attenuated. Pharmacokinetically, PK1 has a distribution t(1/2) of 1.8 h and an elimination t(1/2) averaging 93 h. 131I-labeled PK1 imaging suggests PK1 is taken up by some tumors. Responses (two partial and two minor responses) were seen in four patients with NSCLC, colorectal cancer, and anthracycline-resistant breast cancer. PK1 demonstrated antitumor activity in refractory cancers, no polymer-related toxicity, and proof of principle that polymer-drug conjugation decreases doxorubicin dose-limiting toxicities. The recommended Phase II dose is 280 mg/m2 every 3 weeks. Studies are planned in colorectal, NSCLC, and breast cancer patients.
Studies with a reconstituted muscle glycolytic system. The anaerobic glycolytic response to simulated tetanic contraction (1974)

By using a reconstituted glycolytic system and a highly active adenosine triphosphatase (ATPase), the metabolism during muscular tetanic contraction was simulated and observed. With an ATPase activity somewhat greater than can be maintained in muscle tissue, phosphocreatine was rapidly and completely utilized, lactate production commenced about 5s after the ATPase was added and after 15s adenine nucleotides were lost through deamination to IMP. By 40s, all metabolism ceased because of complete loss of adenine mononucleotides. With a lower ATPase activity, glycolytic regeneration of ATP was capable of maintaining the ATP concentration at its initial value and even by 80s, only one-half of the phosphocreatine had been utilized. No deamination occurred in this time. It is suggested that the metabolic events observed in the simulated system are basically the same as occur in muscle doing heavy work.
Inhibition of lipopolysaccharide synthesis in Agrobacterium tumefaciens and Aeromonas salmonicida (1992)

Lipopolysaccharide (LPS) synthesis was inhibited, new lipid A metabolites accumulated, and growth ceased, when the plant pathogen Agrobacterium tumefaciens and the fish pathogen Aeromonas salmonicida were treated with an antibacterial agent which specifically inhibits CTP:CMP-3-deoxy-manno-octulosonate cytidylyltransferase (CMP-KDO synthase). The new lipid A metabolites were purified by chromatography on DEAE-cellulose and chemically analysed. Metabolites isolated from both bacterial species contained glucosamine and phosphate in a 1:1 molar ratio, and 3-OH-C14:0 was the major fatty acid present (1 mol and 1.4 mol per mol glucosamine for A. tumefaciens and A. salmonicida, respectively). Inhibition of LPS synthesis by CMP-KDO synthase inhibitor had no effect on the initial kinetics of A. tumefaciens attachment to cultured carrot cells, but did inhibit cell aggregation normally induced by bacterial cellulose synthesis. Bacteria treated with inhibitor remained viable and able to synthesize protein at 15% the rate of control cells, indicating that the lack of cellulose-induced aggregation was not due to the inability of bacteria to make protein, but rather the inability to respond normally to the bacterial-plant cell interaction.
Real‐Time Mass Spectrometric Study of the Methanol Crossover in a Direct Methanol Fuel Cell (1996)

The products of methanol crossover through the acid‐doped polybenzimidazole polymer electrolyte membrane (PBI PEM) to the cathode of a prototype direct methanol fuel cell (DMFC) were analyzed using multipurpose electrochemical mass spectrometry (MPEMS) coupled to the cathode exhaust gas outlet. It was found that the methanol crossing over reacts almost quantitatively to at the cathode with the platinum of the cathode acting as a heterogeneous catalyst. The cathode open‐circuit potential is inversely proportional to the amount of formed. A poisoning effect on the oxygen reduction also was found. Methods for the estimation of the methanol crossover rate at operating fuel cells are suggested.
Ketoconazole: A Novel and Rapid Treatment for Advanced Prostatic Cancer (1983)

Ketoconazole is an orally administered broad-spectrum antifungal agent that acts through the inhibition of the steroid synthetic pathways. At high doses in humans ketoconazole can lower rapidly serum testosterone and maintain it in the castrate range with frequent administration. This property suggested that ketoconazole might be useful in the treatment of prostatic cancer. We report a case of prostatic cancer in which ketoconazole resulted in rapid and sustained reduction in serum androgens as well as rapid induction of a clinical remission. Ketoconazole may be a valuable agent in the treatment of prostatic cancer.
