Mouse interferons enhance the accumulation of a human HLA RNA and protein in transfected mouse and hamster cells. (1982)

A recombinant clone (pJY150R1.1) encoding the human major histocompatibility antigen (HLA-B7) was introduced into mouse cells and hamster cells by cotransformation with selectable genes. The exposure to mouse interferon of the cells transformed to HLA-B7+ resulted in a severalfold increase in the level of HLA antigen and RNA. The HLA-B7 clone used for the transfection includes a 670-base pair DNA sequence upstream from the coding segment. It remains to be established if the 670-base pair segment is necessary and/or sufficient to make the transcription of the HLA gene responsive to interferon.

Viscometer calibration standards: viscosities of water between 0 and 60 degrees C and of selected aqueous sucrose solutions at 25 degrees C from measurements with a flared capillary viscometer (1984)

A consistent set of high precision viscosity data for water at various temperatures and for 20, 30 and 40 per cent sucrose solutions is reported. These were obtained using a glass capillary viscometer with an extensively flared capillary. The negligibility of the kinetic energy correction term for this viscometer is confirmed. The reported viscosities are based only on the absolute viscosity of water at 20 degrees C. These data are recommended as reliable standards for capillary viscometer calibration.
Mechanistic Investigation of Particle Size Effects in TEMPO- Mediated Radical Polymerization of Styrene in Aqueous Miniemulsion (2007)

Particle size effects in the diameter range 70−200 nm in 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO)-mediated radical polymerization of styrene in aqueous miniemulsion at 125 °C using sodium dodecylbenzenesulfonate as surfactant have been studied. Extensive investigations, including modeling and simulations of the polymerization, indicate that a significant fraction of free TEMPO is unable to participate in deactivation reactions if the particles are sufficiently small. The results are in support of our previously proposed interface effect [Nakamura, T.; Zetterlund, P. B.; Okubo, M. Macromol. Rapid Commun. 2006, 27, 2014−2018], according to which some fraction of the free TEMPO is located/adsorbed at the interface, thus reducing the effective TEMPO concentration in the organic phase.

Pentoxifylline Inhibits Agonist-Induced Vasoconstriction in Vascular Smooth Muscle and Spontaneous Peristalsis in Isolated Ileum (2005)

Pentoxifylline (PTX) is currently used therapeutically as a tumor oxygenator where it been shown to increase tumor blood flow and potentiate ionizing radiation damage. The clinical benefits of PTX have been primarily attributed to its effect on the rheologic properties of whole blood, although there is speculation that the mechanism for PTX-induced increases in tumor oxygenation may be the direct result of reduced vascular resistance. Therefore, to address the issue of vascular (geometric) resistance directly, we examined the ability of PTX and its hydroxy metabolite, lisofylline (LF), to modulate phenylephrine (PE)-induced constriction in isolated rat tail arteries. PTX or LF significantly attenuated phenylphrine (PE)-induced vasoconstriction in a dose-dependent manner. The EC50 for LF and PTX were 336 and 466 microM, respectively. Gastrointestinal disturbances have been reported following oral ingestion of PTX. To clarify the mechanistic basis for this side effect we examined the potential of PTX to modulate spontaneous peristalsis in isolated rat ileum rings. PTX significantly attenuated the spontaneous contractions (oscillations) in a dose-dependent manner. In comparison to isolated rat arterial vessels, the ileum ring preparations were significantly more sensitive (eightfold) to the relaxing effects of PTX (EC50 58 microM). Our data suggest that PTX- or LF-induced changes in tumor blood flow may be the direct result of vascular smooth muscle relaxation. Furthermore, the gastrointestinal disturbances that have been reported in the literature may be a consequence of PTX-induced inhibition of gut peristalsis.
Evaluation of the Efficacy of Oil-Emulsion Bacterins for Reducing Fecal Shedding of Salmonella enteritidis by Laying Hens (1993)

Two replicate experiments were conducted to test the efficacy of two different Salmonella enteritidis oil-emulsion bacterins (an experimentally prepared acetone-killed vaccine and a commercially available vaccine) for protecting laying hens against intestinal colonization following oral exposure to S. enteritidis. Each vaccine was administered twice (4 weeks apart), and all hens were challenged with 10(8) cells of a nalidixic-acid-resistant S. enteritidis strain 2 weeks after the second vaccination. Fecal samples from vaccinated and unvaccinated control hens were cultured at three weekly intervals post-challenge to determine the incidence of intestinal colonization and the numbers of S. enteritidis shed into the environment. Both vaccines significantly reduced the incidence of intestinal colonization (P < 0.05) and the mean number of S. enteritidis cells shed in the feces (P < 0.01) at 1 week post-challenge. However, the degree of protection afforded by vaccination was only partial, as more than half of the vaccinated hens still shed substantial numbers of S. enteritidis. If used in conjunction with other flock sanitation and infection-monitoring strategies, vaccination with bacterins could potentially reduce the overall level of environmental contamination and thereby also reduce the horizontal transmission of S. enteritidis within and between laying flocks.
Syringomyelic dystonia and athetosis (1999)

Two patients with movement disorders associated with syringomyelia are described, one of whom developed unusual torticollis, and the other had choreoathetoid-dystonic movements of the hand and arm. In each case, the movements resolved with decompression of the syrinx. The literature is reviewed and possible mechanisms explored.
Organic experiences (2013)

Display technology developments mean the next generation of visual output devices will extend beyond the rigid, flat surfaces with which we are familiar to those that the user or the machine can deform. These will allow users to physically push, pull, bend, fold or flex the display and facilitate a range of self-deformation to better represent on-screen content or support new modes of interaction. This workshop will provide a forum to examine, discuss and shape the three primary themes of research in this area: prototyping and implementation, interaction and experience design, and evaluation. It will bring together an interdisciplinary group of academic and industrial researchers to define the current and future challenges of crafting organic user experiences with deformable displays.
Lifetime Evaluation of Nanoscale Silver Sintered Power Modules for Automotive Application Based on Experiments and Finite-Element Modeling (2015)

The thermomechanical behavior of power modules has been always an issue with regard to reliability improvement. Silver sintering technology is one of the few alternatives for die attachment, which could bring a longer operating lifetime. Finite-element modeling (FEM) is as critical as the experimental development for such a new technology. In this paper, we present a lifetime evaluation approach for power modules used in automotive applications due to thermal characterizations, thermal ageing, and thermomechanical FEM analyses. A lower coefficient of thermal expansion mismatch with the silver sintering technology as compared with soldering increases the thermomechanical resistance to thermal swings (about six times). The FEM analyses of the accumulation of the strain energy density help understand and locate the high-stress area in a silver-sintered power module. Finally, this paper leads us to estimate the operating lifetime of silver-sintered assemblies for a specific mission profile by considering the thermomechanical behavior.
Development of a gas-promoted oil agglomeration process. Quarterly technical progress report, April 1, 1996--June 30, 1996 (1996)

A number of agglomeration tests were conducted with finely ground Pittsburgh No. 8 coal to study the effects of various parameters on the size and structure of the agglomerates formed, the rate of agglomeration, coal recovery, and ash rejection. In these tests, concentrated suspensions were treated with i-octane and a limited amount of air in a small laboratory mixing unit. Conditions were identified which affected either the rate of agglomeration or the type of product produced. Some conditions led to the formation of unconsolidated flocs while others led to the production of compact agglomerates. Since the product was recovered by screening, the largest recovery of coal and cleanest product were realized when the product was in the form of compact agglomerates rather than in the form of unconsolidated flocs.
Mass exchange between mobile freshwater and immobile saline water in the unsaturated zone (1988)

A profile of tritium concentrations measured in the unsaturated zone in loessial sediments in a semiarid area is interpreted in terms of mobile and immobile water domains, according to a nonequilibrium transport model. The mobile domain is represented by percolating freshwater from both rain and irrigation, and the immobile one is represented by isolated fossil saline water pockets. The two domains are connected by partially saturated narrow passages within dispersed clay minerals. The transport of the mobile water is described by convective‐dispersive flow and by mass exchange between the two water domains. The relevant equations with the given initial and boundary conditions are solved numerically, and the simulated profile is adjusted to fit the measured one. In this study we concentrate on examination of the mass exchange law between the two domains. It was assumed that matrix characteristics vary in time due to the dispersion of clays at the interface between fresh and saline waters. Accordingly, a time‐dependent mass exchange was adopted, which made it possible to obtain an adequate reconstruction of the measured tritium profile. By using a least squares optimization procedure it was found that the best fit between the simulated and measured profiles is attained when the fraction of mobile water is 30%, and the rate of mass exchange decreases from 0.60 to 0.01 year −1 in 26 years. The proposed model implies is that it is the immobile water domain which contains the memory of the “high tritium period” (thermonuclear tests period) of the 1960s.

Structural reorganization of the rough endoplasmic reticulum without size expansion accounts for dexamethasone-induced secretory activity in AR42J cells (1993)

A striking reorganization of the rough endoplasmic reticulum (RER) from a tubulo-vesicular (TV-RER) to a stacked cisternal (SC-RER) configuration was observed when the secretory activity of AR42J cells, a cell line derived from a rat pancreatic acinar carcinoma, was induced by dexamethasone. Treatment with 10 nM dexamethasone resulted in a 6.6-fold increase in the intracellular and a 4.6-fold increase in the secreted amylase activity, respectively. On the basis of the morphometric analysis of thin-section electron micrographs it has been previously reported that this increase in secretory activity is accompanied by a 2.4-fold or 30-fold increase in the size of the RER. We have developed a new biochemical method to determine the size of the RER by quantifying the membrane-bound ribosomes. Using this procedure we did not detect any change in the size of the RER after induction of an active secretory state in AR42J cells. Electron microscopic observation showed the predominance of SC-RER in dexamethasone-treated cells compared to the abundance of TV-RER in control cells. Laser scanning confocal microscopy showed a patchy distribution of ER staining in dexamethasone-treated cells compared to more basal localization in control cells. On the basis of our observations we conclude that in AR42J cells the increase in secretory activity induced by dexamethasone is accompanied by a reorganization of the RER rather than by an increase in ER surface area, as reported by others. Our results suggest that SC-RER is a biosynthetically more efficient form of the RER, which is found predominantly in actively secreting cells.
The Effect of Applied Growth Hormones on Cambial Division and the Differentiation of the Cambial Derivatives (1966)

When indole-3-acetic acid (IAA) is applied to woody shoots cambial division is stimulated and the cambial derivatives differentiate to produce xylem tissue. When gibberellic acid (GA) is applied, cambial division occurs but the resultant derivatives on the xylem side of the cambium remain undifferentiated. The relative levels of applied IAA and GA are important in determining whether mainly xylem or phloem tissue is produced. High IAA/low GA concentrations favour xylem formation, whereas low IAA/high GA concentrations favour phloem production. The new phloem tissue produced as a result of hormone treatment is fully differentiated, containing sieve elements and sieve plates. IAA is important in promoting the elongation of the cambial derivatives to produce xylem vessel and fibre elements, though in the case of xylem fibres applied GA causes further elongation. IAA is an important factor in determining vessel diameter in the ring-porous species Robinia pseudacacia, high levels of applied IAA giving wide springwood-type vessels and low levels giving narrow ‘summerwood’ vessels.
An estimation method for a cellular-state-specific gene regulatory network along tree-structured gene expression profiles (2012)

We confirmed that the proposed method in cell differentiation was more rigorous than the conventional method. The results show that our assumptions as to which relations are unimportant for understanding the differences of cellular states in cell differentiation are appropriate, and that our method can infer more accurately the core networks of the cell types.
SPARCLE: Electrostatic Tool for Lunar Dust Control (2009)

Successful exploration of most planetary surfaces, with their impact‐generated dusty regoliths, will depend on the capabilities to keep surfaces free of the dust which could compromise performance and to collect dust for characterization. Solving the dust problem is essential before we return to the Moon. During the Apollo missions, the discovery was made that regolith fines, or dust, behaved like abrasive velcro, coating surfaces, clogging mechanisms, and making movement progressively more difficult as it was mechanically stirred up during surface operations, and abrading surfaces, including spacesuits, when attempts were made to remove it manually. In addition, some of the astronauts experienced breathing difficulties when exposed to dust that got into the crew compartment. The successful strategy will deal with dust dynamics resulting from interaction between mechanical and electrostatic forces. Here we will describe the surface properties of dust particles, the basis for their behavior, and an electrostatically‐based approach and methodology for addressing this issue confirmed by our preliminary results. Our device concept utilizes a focused electron beam to control the electrostatic potential of the surface. A plate of the opposite potential is then used to induce dust migration in the presence of an electrical field. Our goal is a compact device of <5 kg mass and using <5 watts of power to be operational in <5 years with heritage from ionic sweepers for active spacecraft potential control (e.g., on POLAR). Rovers could be fitted with devices that could harness the removal of dust for sampling as part of the extended exploration process on Mercury, Mars, asteroids or outer solar system satellites, as well as the Moon.
SHS of TiC-TiNi composites: Effect of initial temperature and nanosized refractory additives (2012)

For SHS reactions in Ti-Ni-C powder blends yielding TiC-TiNi composites, investigated was the effect of initial temperature (T 0), green composition, and nanosized refractory additive (alloying agent) on combustion parameters and structure formation in combustion products. An increase in T 0 elevated combustion temperature T and burning velocity U, while the addition of micro- and nano-sized ZrO2 particles diminished the above parameters due to partial blocking of reactive Ti-Ni contacts by ZrO2 agglomerates. At the same time, the addition of alloying agents enlarged the number of crystallization centers for the growth of primary TiC grains in the melt.
Thin Film Refractive Index Determination By Different Techniques (1986)

The refractive index of some dielectric thin films has been determined by three different techniques. Spectrophotometry, ellipsometry and a technique based on the Abeles method are chosen for the analysis of the prepared samples in the visible spectrum. The first technique is the most widely used for obtaining a quick evaluation of the refractive index but, in order to get accurate results, a complex data processing is necessary. The second one is the most accurate but the experimental apparatus is rather complex and a skilled operator is generally required. The third technique is simpler than ellipsometry and a comparable accuracy on the refractive index determination can be obtained but only for transparent films. The relative advantages and limits of these techniques make each of them more or less convenient depending on the sample properties. Results are compared in areas where all three methods are successfully used.
Myoclonic epilepsy of lafora and arylsulphatase a deficiency in the same patient (1889)

Very low levels of arylsulphatase A were found in a young patient with the clinical features of Lafora disease, confirmed by muscle biopsy. The deficiency was shown both in leukocytes and cultured fibroblasts. A cerebroside sulphate loading showed that 93% of [14C]cerebroside sulphate taken up by skin fibroblasts from the patient remained unmetabolized after a 24h pulse, ruling out pseudo-arylsulphatase A deficiency. In the healthy parents and siblings of the patient, biochemical data suggested heterozygosity for arylsulphatase A deficiency. The apparent co-inheritance of arylsulphatase A deficiency and Lafora disease in this family might be the consequence of genetic linkage between the two genes.
Further progress in laser welding of ceramics (1993)

Laser welding of ceramic parts of alumina with two laser beams has been almost done successfully at the Laser Centre of Mittweida since 1986. The progress in solving the problems of welding this material by means of laser radiation is shown in the following paper. An introduction concerning some welding-related properties of ceramic materials will be given: thermal properties - such as heat conductivity and resistance to thermal shocks will be discussed. Measurements of absorptivity at 1060 nm show that the low absorption coefficient increases above temperatures of about 1000 K. Investigations of thermal stresses, which must be minimised for crackfree welding, show the necessity of preheating. One can preheat the whole workpiece or part of it using different preheating methods. The welding method for alumina with two laser beams (one is used for preheating) shows how to use different laser wavelengths for getting various shapes of the welding heat source due to the different value of absorptivity. An investigation of the laser welded parts of alumina reveals the different micro structure in the heat affected zone and grain sizes within the melted zone which vary with the cooling rate. It should be possible to use this new welding technique for the realisation of more complicated shapes of ceramic parts in comparison with conventional machining of sintered parts.
Improvement in the efficiency of an OrganoMetallic Fuel Cell by tuning the molecular architecture of the anode electrocatalyst and the nature of the carbon support (2012)

The electrooxidation of ethanol to acetate is achieved with Rh(I) diolefin amine complexes of the general formula [Rh(Y)(trop2NH)(L)] (L = PPh3, P(4-n-BuPh)3; Y = triflate, acetate; Bu = butyl) in direct alcohol fuel cells that have the peculiarity of containing a molecular anode electrocatalyst and, hence, are denoted as OrganoMetallic Fuel Cells (OMFCs). Changing the carbon black support from Vulcan XC-72 (Cv) to Ketjenblack EC 600JD (Ck) and/or the axial phosphane to produce non crystalline complexes has been found to remarkably change the electrochemical properties of the organorhodium catalysts, especially in terms of specific activity and durability. An in-depth study has shown that either Ck or P(4-n-butylPh)3 favour the formation of an amorphous Rh-acetato phase on the electrode, leading to a much more efficient and recyclable catalyst as compared to a crystalline Rh-acetate complex which is formed on Cv with PPh3 as the ligand. The ameliorating effect of the amorphous phase has been ascribed to its higher number of surface complex molecules as compared to the crystalline phase. A specific activity as high as 10 000 A gRh−1 has been found in a half cell, which is the highest value ever reported for ethanol electrooxidation.
