Cationic liposomes bearing IL-2 on their external surface induced mice leukocytes to kill human cervical cancer cells<i>in vitro</i>, and significantly reduced tumor burden in immunodepressed mice (2010)

Tumor cells are known to modify their surroundings in order to escape immunologic detection, and IL-2, a killer cell activator, is one of the factors known to overcome this escape mechanism. In this regard, when we cocultured cells from the human cervical cancer cell line INBL with mice blood leukocytes, no inhibition of tumor cell growth was observed, but when a similar coculture was done in the presence of cationic liposomes bearing IL-2 on their external surface (CL-IL-2), all the INBL cells were killed. In order to evaluate whether this in vitro property of CL-IL-2 to overcome tumor cell detection by lymphocytes could also be reproduced in vivo, INBL cells were intraperitoneally (i.p.) inoculated into immunodepressed mice to produce solid tumors. We observed that the subsequent i.p. delivery of CL-IL-2 rendered the tumor masses significantly smaller. The presence of a large number of infiltrating lymphocytes on those tumors, and the fact that many had a cytotoxic CD8(+) phenotype suggests that these lymphocytes were responsible for the observed antitumor effect. Finally, the possible formation of a bridge between the IL-2R receptors on both, the lymphocytes and the INBL cells, mediated by the IL-2-bearing liposomes, and its possible effect on the activation of antitumor cytotoxic lymphocytes is discussed.
The nucleotide sequence of the nitrogen-regulation gene<i>ntrA</i>of<i>Klebsiella pneumoniae</i>and comparison with conserved features in bacterial RNA polymerase sigma factors (1985)

The nucleotide sequence of the Klebsiella pneumoniae ntrA gene has been determined. NtrA encodes a 53,926 Dalton acidic polypeptide; a calculated molecular weight which is significantly lower than that determined by SDS polyacrylamide gel analysis. NtrA is followed by another open-reading frame (orf) of at least 75 amino acids. In the spacer region between ntrA and orf there are no apparent transcription termination or promoter sequences and therefore orf may be co-transcribed with ntrA. Previous authors have proposed that NtrA could act as an RNA polymerase sigma factor but the NtrA amino acid sequence does not show a high level of homology to any known sigma factor. However analysis of sequences of five sigma factors from E. coli and B. subtilis has identified two conserved sequences at the C-terminal end of all these polypeptides. These sequences resemble those found in known site-specific DNA-binding domains and may be involved in recognition of conserved -35 and -10 promoter sequences. A similar pair of sequences is present at the C-terminus of NtrA and could play a role in recognition of ntr-activatable promoters.

Clinical Performance of Screw- Versus Cement-Retained Fixed Implant-Supported Reconstructions—A Systematic Review (2014)

Although no statistical difference was found between cement- and screw-retained reconstructions for survival or failure rates, screw-retained reconstructions exhibited fewer technical and biologic complications overall. There were no statistically significant differences between the failure rates of the different reconstruction types (I-SCs, I-FDPs, full-arch I-FDPs) or abutment materials (titanium, gold, ceramic). The failure rate of cemented reconstructions was not influenced by the choice of a specific cement, though cement type did influence loss of retention.
Magnetron Cathodes (1946)

The multicavity magnetron imposes exceedingly severe requirements upon its cathode. Spectacularly high electron emissions have been observed under pulsed conditions. Cathode parameters are obtained by interpreting, in terms of the emission equations, data secured using rectangular microsecond pulses. Emission densities exceeding 50 amperes per square centimeter, limited only by sparking, have been attained, and several forms of current-versus-voltage characteristic may be identified. Sparking may be precipitated by phenomena originating either in the cathode or anode. Two competing mechanisms for cathode-initiated sparking have been established experimentally. The resistance of the oxide coating results in a pulse-temperature rise during the flow of high currents. Resistance values of 1 to 100 ohm-centimeters squared, deduced from measurements of this effect, agree with those obtained in experiments performed with cathodes having probes embedded within the coating. The secondary emission of oxide-coated cathodes varies with temperature in an exponential manner from approximately 4 to 7 at room temperature to 100 at 850 degrees centigrade for a cathode activated to the optimum. Magnetrons have been operated solely by secondary emission as a consequence of the back-bombardment of the cathode. Measurements have revealed that 3 to 20 per cent of the output power may be dissipated in this manner. Correlations have been established between magnetron performance and cathode emission. The high-current-mode boundary depends upon the available thermionic emission. Undesired emission from certain regions of the cathode may introduce losses.
An extensometer for low-cycle fatigue tests on anisotropic materials at elevated temperatures (1979)

An extensometer for axial strain-controlled low-cycle fatigue tests on anisotropic structural materials at temperatures up to 816 degrees C is described. The unique features of this extensometer are that it is designed to be supported by counter weights when attached to a uniform-gauge specimen, and that the probe tips are held in place by friction. Results of tests on austenitic stainless steel weld-metal specimens indicate that the extensometer provides accurate cyclic strain control and has excellent thermal and electronic stability for tests of up to 4.5*106 s duration.
RHEOLOGICAL PROPERTIES OF THE PARTIALLY HYDROPHOBIC MONTMORILLONITE TREATED WITH ALKYLTRIALKOXYSILANE (1995)

Montmorillonite was treated with a small amount of aliphatic alkyltrialkoxysilanes with different lengths of alkyl chains in dry air. The alkyltrialkoxysilane molecules were chemically bonded on to the edge surface of the silicate layers of montmorillonite. Rheological behavior of the aqueous suspensions of the products was investigated as a function of the number of carbon atoms in the alkyl chain. The viscosity of the suspensions considerably increased with the increase of the number of carbon atoms in the alkyl chain and the type of flow changed to a typical Bingham flow, whereas the original montmorillonite suspension exhibited a pseudoplastic or socalled shear-thinning flow. The Robinson's viscosity equation and the intrinsic viscosity model of an oblate ellipsoid given by Kuhn and Kuhn (Guven, 1992) were applied to the viscosity data of the aqueous suspensions for the explanation of the particle characteristics of montmorillonite treated with n-hexyltrimethoxysilane. An appreciable increase of the intrinsic viscosity of the montmorillonite treated with n-hexyltrimethoxysilane suggested the formation of a lamellar structure of developed edge-to-edge arrangement of particles, due to the hydrophobic bonding of the alkyl chains on the edge surface. The product is expected to be useful industrially as a rheology-controlling agent for various aqueous fluid products.

Properties of nanocomposite coatings prepared by hybrid processof metallic target sputtering in argon and acetylene (2011)

The contribution reports on properties of nc-TiC/a-C:H coatings
consisting of TiC (titanium carbide) crystallites of
characteristic size ranging from several to several tens of nm
embedded in hydrogenated carbon based matrix. The coatings were
prepared by a hybrid deposition process combining PVD
(sputtering of metallic target) and PECVD (plasma in mixture of
Ar and acetylene) aspects. These coatings are usually prepared
at conditions of very high ion bombardment. We have shown that
only relatively low ion bombardment is enough to prepare
coatings of very good quality (good adhesion, high hardness and
Young’s modulus). Moreover, at these conditions, the stress in
the coating is very low and coating with high thickness (even
10 micrometers) can be prepared.
Influence of Project Type and Procurement Method on Rework Costs in Building Construction Projects (2002)

While it is widely recognized that additional costs due to rework can have an adverse effect on project performance, limited empirical research has been done to investigate the influencing factors. The research presented in this paper aims to determine the influence of different project types and procurement methods on rework costs in construction projects. Using a questionnaire survey, rework costs were obtained from 161 Australian construction projects. The direct and indirect consequences of rework are analyzed and discussed. It is shown that, contrary to expectation, rework costs do not differ relative to project type or procurement method. In addition, it was found rework contributed to 52% of a project’s cost growth and that 26% of the variance in cost growth was attributable to changes due to direct rework. To reduce rework costs and therefore improve project performance, it is posited that construction organizations begin to consider and measure them, so that an understanding of their magnitude can be captured, root causes identified, and effective prevention strategies implemented.
Pneumonia Versus Aspiration Pneumonitis in Nursing Home Residents: Prospective Application of a Clinical Algorithm (2005)

Distribution of episodes of suspected pneumonia by clinical category as determined using the algorithm was similar to that of the derivation study, as were case fatality rates in each category. These findings suggest that the algorithm may be useful for making the distinction between pneumonitis and pneumonia in nursing home residents; further studies are warranted.
GPCR Signaling: Understanding the Pathway to Successful Drug Discovery (2009)

Modulators of G protein-coupled receptors (GPCRs) form a key area for the pharmaceutical industry, representing approximately 27% of all Food and Drug Administration (FDA)-approved drugs. Consequently, there are a wide variety of in vitro plate-based screening technologies that enable the measurement of compound affinity, potency, and efficacy for almost every type of GPCR. However, to maximize success it is prudent to ensure that (i) the most suitable assay formats are identified, (ii) they are configured optimally to detect the desired compound activity, and (iii) that they form a basis for predicting clinical effects. To achieve this, an understanding of the pathways and mechanisms of receptor activation relevant to the disease mechanism, as well as the benefits and/or limitations of the specific techniques, is key.
Endotoxemia in Sudden Infant Death Syndrome (1994)

Endotoxemia has been proposed as a significant cause of Sudden Infant Death Syndrome (SIDS). We examined postmortem sera from left and right heart samples of 21 SIDS cases (1989 definition) and 23 controls. The controls were < 1 year of age and had died suddenly and unexpectedly of infection, abuse, suffocation, blunt injury, or fire and smoke inhalation. Endotoxin was measured without knowledge of the clinical status by using a kinetic modification of the chromogenic limulus amoebocyte lysate assay. The SIDS cases had insignificant concentrations of endotoxin in serum, whereas some of the controls who experienced blunt injury, abuse, or severe infection exhibited moderately elevated concentrations. Postmortem interval and postmortem blood culture results did not materially affect endotoxin concentrations. Thus, we conclude that endotoxemia is not a substantial pathophysiologic event in SIDS.
The effects of conducting breaks on electrostatic discharges (ESDs) on optical solar reflector (OSR) panels (1992)

Charging tests were performed on a 21-cm*21-cm panel covered with a square of 25 fused-silica OSRs. In subsequent tests the middle rows and for columns were replaced with ITO (indium tin oxide)-coated OSRs. This did not stop the propagation of discharges, which apparently jumped across the conducting gaps generating multiple unipolar current pulses. A propagation model can be used to predict transient amplitude and propagation delay across conducting gaps (separation between the current pulses).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Influence of F and Cl on the recrystallization of ion-implanted amorphous Si (1984)

The effect of fluorine and chlorine implantation on the solid-phase epitaxial regrowth of amorphized 〈100〉 Si was studied in intrinsic and heavily boron doped material. Annealings were performed at 500 and 600 °C. Both F and Cl retard the regrowth rate at 500 °C. The growth rates are much faster in B-doped than in undoped Si. Complete regrowth in B-doped Si is obtained for all investigated doses of fluorine up to 5×1015 F/cm2 at 600 °C for 30 min. The highest dose of chlorine (5×1015 Cl/cm2) stops the regrowth at this temperature.

Synthesis of solar fuels by a novel photoelectrocatalytic approach (2010)

The characteristics of nanostructured (a) TiO2 thin films (based on an ordered array of titania nanotubes) and their performances as photoanode in H2 production by water splitting or photoreforming of ethanol (in liquid or gas phase) and (b) carbon-nanotube based electrodes for the gas-phase reduction of CO2 to liquid fuels (mainly isopropanol) are discussed together with their application for the design of a novel photoelectrocatalytic approach for the synthesis of solar fuels.
Theory of self-diagnostic sensor array devices using gas-sensitive resistors (1995)

The principles of operation of self-diagnostic gas-sensitive resistors are described. Such sensors use arrays of electrodes, on a single device, to probe the concentration profiles of target gases. Theoretical treatments are presented to show the application of such devices in distinguishing gases with differing ratios of reaction to diffusion rates, compensating for relative humidity, and detecting poisoning of the gas-sensing material. The transient behaviour of the devices is also modelled, demonstrating their potential use for resolving mixtures of gases having differing kinetic timescales, by producing a ‘gas chromatograph’ type of result.
Breakdown voltages in SF/sub 6/+argon mixtures under nonuniform electrostatic fields (2002)

This study presents the experimental findings in SF/sub 6/+Ar binary mixtures under nonuniform electrostatic fields for different contents of SF/sub 6/ in the mixture. The discharge inception and breakdown voltages were monitored at 50 kPa and 100 kPa of total gas pressure. The breakdown strength of SF/sub 6/+Ar has increased dramatically with small percentage of SF/sub 6/. However, for higher SF/sub 6/ contents, the breakdown voltages did increase monotonically but not dramatically, and indicated a more pronounced corona stabilization activity.
Strategies to prevent or control infections after bone marrow transplants. (1991)

Patients receiving bone marrow transplants are at risk of life-threatening infections early post-transplant. This predisposition results from extensive mucosal damage and severe granulocytopenia. Common causes of infection include bacteria and fungi. Infections with opportunistic pathogens occur later and are associated with defects in cellular and/or humoral immunity. The most common sites of infections are the gastrointestinal tract, oropharynx, lung, skin and indwelling vascular catheters. Empiric approaches designed to treat common bacterial and fungal pathogens are generally effective as are measures designed to prevent dissemination of infections. These approaches are also used to prevent fungal infections.
A Cache Architecture for Counting Bloom Filters (2007)

Within packet processing systems, lengthy memory accesses greatly reduce performance. To overcome this limitation, network processors utilize many different techniques, e.g., utilizing multi-level memory hierarchies, special hardware architectures, and hardware threading. In this paper, we introduce a multi-level memory hierarchy and a special hardware cache architecture for counting Bloom filters that is utilized by network processors and packet processing applications such as packet classification and distributed web caching systems. Based on the value of the counters in the counting Bloom filter, a multi-level cache architecture called the cache counting Bloom filter (CCBF) is presented and analyzed. The results show that the proposed cache architecture decreases the number of memory accesses by at least 51.3% when compared to a standard Bloom filter.
Time series analysis and forecasting techniques for correlated observations (2004)

This work deals with nonstationary signals processing of blood cells. The signals under study are represented in a time-scale and statistical techniques are used to characterize their behavior and to identify a data pattern, then assuming that it will continue in the future, this data pattern is extrapolated in order to produce forecasts. The resulting fitted ARMA models allowed us to know in advance future values into a confidence range.
Survey of crop losses in response to phytoparasitic nematodes in the United States for 1994. (1999)

Previous reports of crop losses to plant-parasitic nematodes have relied on published results of survey data based on certain commodities, including tobacco, peanuts, cotton, and soybean. Reports on crop-loss assessment by land-grant universities and many commodity groups generally are no longer available, with the exception of the University of Georgia, the Beltwide Cotton Conference, and selected groups concerned with soybean. The Society of Nematologists Extension Committee contacted extension personnel in 49 U.S. states for information on estimated crop losses caused by plant-parasitic nematodes in major crops for the year 1994. Included in this paper are survey results from 35 states on various crops including corn, cotton, soybean, peanut, wheat, rice, sugarcane, sorghum, tobacco, numerous vegetable crops, fruit and nut crops, and golf greens. The data are reported systematically by state and include the estimated loss, hectarage of production, source of information, nematode species or taxon when available, and crop value. The major genera of phytoparasitic nematodes reported to cause crop losses were Heterodera, Hoplolaimus, Meloidogyne, Pratylenchus, Rotylenchulus, and Xiphinema.
Overexpression of G1-S Cyclins and Cyclin-Dependent Kinases during Multistage Human Pancreatic Duct Cell Carcinogenesis (2004)

The results provide additional insight into the mechanism of G1-S cell cycle checkpoints deregulation during stepwise pancreatic duct cell carcinogenesis, and suggest a p16-independent role for cyclin D3 in deregulating the G1 cell cycle checkpoints during early stages of pancreatic duct cell carcinogenesis.
Increasing Risk of Relapse after Treatment of Clostridium difficile Colitis in Quebec, Canada (2005)

In 2003-2004, there was an increase in the proportion of patients with CDAD believed, by their attending physicians, to have experienced metronidazole treatment failure, as well as an increase in the frequency of post-metronidazole therapy recurrences, especially among elderly persons.
