RELATIVE STORABILITY OF HIGHOIL AND BT CORN HYBRIDS COMPARED TO CONVENTIONAL HYBRIDS (2003)

The objectives of this study were to compare relative storability for five pairs of normaloil content and highoilcontent corn (Zea mays) hybrids, and for five pairs of conventional and Bt corn hybrids, stored at 20.C (68.F) and at twodifferent moisture values (19% and 22%, wet basis). Paired hybrids had similar parent genetics. Carbon dioxide productionby corn samples was used to calculate dry matter loss (DML), and time to 0.5% DML was used as the primary indicator ofstorability. Change in the fat acidity content of normaloil and highoil corn hybrids was determined and used as anotherpossible indicator of relative storability.<br><br>The mean adjusted times to 0.5% DML for normaloil and highoil corn hybrids were significantly different at a 0.05probability level for all five hybrid pairs at 19% moisture, but time to 0.5% DML was significantly different for only two hybridpairs at 22% moisture. The deterioration rate for highoil corn was faster than for normaloil corn in most hybrid pairs atboth 19% and 22% moisture. Fat acidity values were significantly different at a 0.05 probability level for all hybrid pairs atboth moisture levels, both before and after storability tests. Fat acidity values for highoil corn hybrids were much higherthan for comparable normaloil content corn hybrids after the test. There was a strong positive correlation between oil contentand fat acidity after storability tests at both moistures. In general, the highoil corn hybrids had higher levels of damagedkernels (DKT) at the end of the storability tests, at both 19% and 22% moisture. Fat acidity and DKT results indicate that,at a given moisture content, some highoil corn hybrids might not store as well as normaloil content corn.<br><br>For conventional and Bt corn hybrids, the mean adjusted times to 0.5% DML were significantly different at a 0.05probability level for three hybrid pairs at 19% moisture and for four hybrid pairs at 22% moisture. In some cases, time to 0.5%DML was greater for the conventional hybrid, and in other cases, time to 0.5% DML was greater for the Bt hybrid. Differencesin fungal counts and DKT values after storability tests were small for comparable hybrid pairs of conventional and Bt cornat both moisture levels. These results do not allow any conclusions to be drawn about the relative storability of Bt corn hybridscompared to conventional hybrids.
Detection of a 58-Kilodalton High Density Lipoprotein-Binding Protein in the Membrane Fraction of Luteinized Rat Ovaries* (1990)

The membrane fraction from the ovaries of pseudopregnant rats exhibits specific, high affinity binding of high density lipoproteins (HDL). Previous studies have indicated that HDL binding in this tissue is up-regulated by hCG and may be involved in supplying cholesterol as substrate for steroid hormone production. To characterize the HDL-binding activity, we solubilized the membrane proteins using 40 mM beta-octylglucoside and then separated them by electrophoresis on a 7% sodium dodecyl sulfate-polyacrylamide gel. The separated proteins were transferred to nitrocellulose sheets and subsequently incubated in the presence of [125I]apolipoprotein-E-free HDL. Autoradiography of the nitrocellulose revealed that the labeled HDL was bound to a single major band, with an apparent mol wt of 58,000 daltons. Neither reduction with beta-mercaptoethanol nor heat denaturation before separation on the gel affected the molecular size of the band, which indicates that it is probably a single polypeptide chain. The band was up-regulated in this tissue by in vivo treatment with 25 IU hCG in a time-dependent manner similar to the up-regulation of [125I]HDL-binding activity. In contrast to the binding of low density lipoprotein (LDL) to its receptor, the binding of HDL is independent of Ca+2. Incubation of the transferred proteins in the presence of [125I] Incubation of the transferred proteins in the presence of [125I]apolipoprotein-E-free HDL and either 5 mM CaCl2 or 15 mM EDTA had no effect on the appearance of the 58-kDa band. Furthermore, ligand blotting in the presence of a 100-fold excess of LDL did not affect the appearance of the band, whereas a 100-fold excess of apoliprotein-E-free HDL caused the disappearance of the band, indicating specificity for binding of HDL. Treatment of the sample with trypsin before electrophoresis also caused the band to disappear, revealing the protein nature of the band. These experiments indicate that the HDL receptor in luteinized rat ovaries is a 58,000-dalton protein.
Model of Detecting Nonmagnetic Cavities in Ferrofluid for Biological Sensing Applications (2006)

We propose a novel method for detecting large bioparticles (e.g., viruses, cells, bacteria) using solid-state magnetic field sensors and utilizing magnetic fluid (e.g., ferrofluid) to provide magnetic susceptibility contrast for the nonmagnetic bioparticle. The proposed sensing approach measures the volume of the bioparticle directly for known particle/substrate separation, effectively overcoming deficiencies with conventional magnetic tagging. An exact analytical solution was developed in bispherical coordinates for the bioparticle's field near the interface, and we compare this solution both with the first-order approximation of a dipole and its induced image, and with a numerical finite-element solution. The results indicate that the dipole-image model works well for most of the particle/substrate separations considered, however, for very small separation or large fluid permeability the dipole-image model can deviate from the exact solution

The effect of a synthetic 7‐thiaprostaglandin E<sub>1</sub> derivative, TEI‐6122, on monocyte chemoattractant protein‐1 induced chemotaxis in THP‐1 cells (1995)

1 The ability of various prostaglandins (PGs) to inhibit monocyte chemotaxis induced by monocyte chemoattractant protein-1 (MCP-1) was investigated with a human monocytic leukaemia cell line, THP-1. Moreover, to investigate the mechanism of the inhibitory action of PGs the involvement of either intracellular adenosine 3': 5'-cyclic monosphosphate (cyclic AMP) accumulation or intracellular Ca2+ mobilization was studied. 2 TEI-6122, a synthetic 7-thia-PGE1 derivative, inhibited chemotaxis of THP-1 cells induced by MCP-1 with an IC50 of 1.5 pM. Its inhibitory activity was 1000 fold more than that of PGE1 and PGE2 (IC50 = 2.8 nM and 0.9 nM, respectively), which were more potent than other PGs such as PGA1, PGA2, PGF2 alpha and PGI2 (IC50 > or = 1 microM). 3 With respect to the effect on intracellular cyclic AMP accumulation in THP-1 cells, TEI-6122 was as potent as PGE1 and PGE2, which were approximately 100 to 1000 fold more potent than the other PGs such as PGA1, PGA2 and PGI2. The minimum concentration of TEI-6122 required to increase intracellular cyclic AMP accumulation in THP-1 cells was 1 nM. 4 TEI-6122 and PGE1 (4 microM) transiently increased intracellular calcium levels in THP-1 cells. When added prior to MCP-1, both PGs partially suppressed the increased in Ca2+ caused by this cytokine. There were no significant differences between the activity of TEI-6122 and PGE1 in either respect. 5 It is concluded that TEI-6122, a synthetic 7-thia-PGE1 derivative is a much more potent inhibitor of MCP-1-induced THP-1 cell chemotaxis than PGEI and PGE2 which are the best inhibitors among the natural PGs tested, while neither intracellular cyclic AMP accumulation nor effects on Ca2+ mobilization account for the extremely potent inhibitory activity of TEI-6122. Thus, either a novel PGE2 receptor (EPreceptor) or a novel intracellular signal transduction system may be involved in the extremely potent chemotaxis inhibitory activity of TEI-6122.
Two Cases of Malignant Hypertension with Reversible Diffuse Leukoencephalopathy Exhibiting a Reversible Nocturnal Blood Pressure "Riser" Pattern. (2002)

We report two cases of malignant hypertension with reversible diffuse leukoencephalopathy demonstrating a nocturnal blood pressure (BP) rising pattern ("riser" pattern). Case 1 was a 54-year-old man diagnosed with malignant hypertension who presented with diffuse leukoencephalopathy and nocturnal BP rise during the acute phase. These abnormal findings diminished after treatment of hypertension. Case 2 was a 50-year-old woman diagnosed with malignant hypertension in association with leukoencephalopathy, heart failure and acute renal failure. She also presented with a "riser" pattern during the acute phase. In contrast to case 1, the leukoencephalopathy and "riser" pattern in case 2 were not improved even after 1 month of treatment. Following intensive antihypertensive treatment, renal failure was improved in case 1, but renal failure was not improved after 1 month in case 2. In conclusion, a possible explanation of this phenomenon is that a causative volume overload due to renal dysfunction produced the temporal leukoencephalopathy-like brain edema and "riser" pattern in these cases.

Molecular Models for DSMC Simulations of Metal Vapor Deposition (2011)

The direct simulation Monte Carlo (DSMC) method is applied here to model the electron‐beam (e‐beam) physical vapor deposition of copper thin films. A suitable molecular model for copper‐copper interactions have been determined based on comparisons with experiments for a 2D slit source. The model for atomic copper vapor is then used in axi‐symmetric DSMC simulations for analysis of a typical e‐beam metal deposition system with a cup crucible. The dimensional and non‐dimensional mass fluxes obtained are compared for two different deposition configurations with non‐uniformity as high as 40% predicted from the simulations.
Linear detection for the nonorthogonal amplify and forward protocol (2009)

In this paper, we present three new detection schemes for the nonorthogonal amplify and forward (NAF) protocol in a cooperative diversity system based on a multiuser detection approach, namely, a channel inversion type detector, a maximal-ratio combining (MRC) type detector, and a biased maximum likelihood (ML) detector. The decision variables in these schemes are linear functionals of the transmitted symbol vector and therefore they are termed as ldquolinearrdquo detectors. A cooperative relay network using the NAF protocol with N - 1 relays is considered where the source transmits symbols in N - 1 blocks of two time slots in a Rayleigh fading environment. For the case of a general linear space-time block coding scheme using K symbols, we present the performance of this protocol in terms of the code symbol error probability when the symbols come from an M-ary phase-shift keying constellation. The approach is further extended to the transmission in N - 1 blocks of L time slots. Numerical results show that the performance of the MRC type detector is superior to that of the channel inversion type detector, while the biased ML detector has the best performance. However, the MRC type detector has the lowest complexity while the biased ML detector the highest.

Palladium Complexes Containing Large Fused Aromatic N−N Ligands as Efficient Catalysts for the CO/Styrene Copolymerization (2006)

Bis(homoleptic) palladium(II) complexes of the extended aromatic ligands eilatin ([Pd(eil)2][BF4]2 (1a)) and dipyridophenazine ([Pd(dppz)2][BF4]2 (2a), [Pd(dppz)2][PF6]2 (2b)) were synthesized and employed in the copolymerization of carbon monoxide and styrene. The eilatin ligand in the complex [Pd(eil)2][BF4]2 is bound via its less hindered “head” coordination site. The X-ray structure of 2b was solved and indicated a highly twisted square planar geometry around the palladium center and the presence of π-stacking interactions of two types. All complexes were found to be active catalysts for the synthesis of the syndiotactic CO/styrene polyketone, their activity exceeding that of the parent complex [Pd(phen)2][BF4]2.
The Role of CMV Inflammatory Genes in Hearing Loss (2007)

Update: Releasing the Brakes on Antitumor Immune Response (1996)

AS is the case with firearms, the destructive capacity of the immune system must be carefully aimed and just as carefully regulated. A report by Leach et al. (1 ) in this issue is an encouraging example of how the receptors that regulate immune responsesin this case, CTLA-4, which was discussed in a recent Perspective (2)-can be directly targeted for immunotherapy. T cell activation is normally self-limited so that the immune system returns to a baseline state once the offending antigen has been cleared. Initiation of T cell activation requires two signals, a major histocompatibility complex (MHC) antigen-specific signal delivered through the T cell receptor (3) and a constimulatory signal, the best characterized of which is delivered through the CD28 receptor (4). Each of these receptors has a counterregulatory cousin that recognizes the same ligand but delivers an opposing negative signal. The counterregulatory receptor for the T cell receptor is from the natural killer (NK) receptor gene family [first discovered on NK cells but also expressed on T cells (5)] CTLA-4 is the counterregulatory receptor for CD28; it binds B7 with roughly 10-fold higher affinity than does CD28. Occupancy of CTLA-4 directly counters the effects of CD28 on T cell activation (6): CD28 cross-linking increases lymphokine secretion by activated T cells, whereas CTLA-4 cross-linking decreases lymphokine production. Neither the NK receptor nor CTLA-4 is expressed on resting T cells; rather, they become induced after T cell activation. These delayed kinetics of expression are responsible for the characteristic self-limited nature of T cell activation. The importance of CTLA-4 in T cell homeostasis in vivo is most dramatically exemplified in CTLA-4 knockout mice. These mice develop a severe lymphoproliferative disease with immunologically mediated organ destruction (7). Manipulation of these counterregulatory receptors in vivo has now entered the realm of cancer immunotherapy. Leach et al. have registered a success in this endeavor by injecting antibodies to CTLA-4 (anti-CTLA-4) into mice with tumors,
Studies on the Joule Effect of Rubber. II. Thermal Effect on Stretched Latex Vulcanizates (1937)

Abstract Latex vulcanizates behave with regard to the Joule effect similarly to ordinary vulcanized rubber when heated and cooled in a stretched condition. The observed thermal effect is assumed to represent the Joule effect. This effect is reduced chiefly by depolymerization and disaggregation of the rubber, and is increased by vulcanization, which may be followed by polymerization of vulcanized rubber molecules and an increase of the polar affinity of each molecule and micelle.
Reactive and anisotropic etching of magnetic tunnel junction films using pulse-time-modulated plasma (2007)

Reactive and anisotropic etching of magnetic tunnel junction (MTJ) stacked films has been achieved using pulse-time-modulated (TM) plasma. While corrosion and delamination of MTJs are observed in continuous wave discharge plasma, a chlorine pulse-time-modulated plasma achieved a high MTJ etching rate without corrosion or delamination. The authors think that the negative ions enhance the chemical reactions on the surface of magnetic films. The magnetic characteristics are also significantly improved by using TM plasma because of reduced residues and improved tapered profiles. Accordingly, TM plasma etching is a promising candidate for high-rate and damage-free MTJ etching for magnetoresistive random access memory devices.

Enzymatic Synthesis of Cytidine Diphosphate 3,6-Dideoxyhexoses (1974)

Abstract In this paper is described a method for the purification of CDP-d-glucose pyrophosphorylase from a rough mutant of Pasteurella pseudotuberculosis type V which yields an enzyme 50% pure with high specific activity. When this material is subjected to gel electrophoresis at pH 7.5, the activity can be identified with one of the two major bands on the gel. By means of Sephadex gel filtration and sodium dodecyl sulfate-polyacrylamide gel electrophoresis studies, the enzyme was found to be a single subunit composed of a single polypeptide chain of molecular weight 110,000. Michaelis-Menten kinetics was observed for the four compounds utilized by the enzyme. Values of Km for each of the substrates are as follows: CTP, 0.11 mm; glucose 1-phosphate, 0.11 mm; CDP-d-glucose, 0.41 mm; and Mg2-PPi, 0.43 mm. The enzyme requires a divalent cation for activity, cobalt being the most active in the direction of CDP-glucose synthesis and magnesium and cobalt in the direction of pyrophosphorolysis. The enzyme was inhibited by CDP-ascarylose, CDP-abequose, and a mixture of CDP-d-fucose and CDP-6-deoxy-d-glucose. The inhibition by CDP-ascarylose is characterized by nonlinear Dixon plots of 1/v versus I, a Hill plot with a slope of 2.3 for I, but linear Lineweaver-Burk plots for CTP and glucose 1-phosphate in the presence of the inhibitor. The presence of CDP-ascarylose causes a 10-fold increase in the Km for CTP, but Km for glucose 1-phosphate remains unchanged. The possible implications of these results are discussed.

Theoretical coupling longitudinal-transverse model and experimental verification of transverse vibration of rope for multi-rope friction hoisting system (2016)

Using the mass of time-varying length balance rope focused on the hoisting conveyance, the coupling longitudinal-transverse model of mine friction hoist was established by using of the Hamilton’s principle. The modified Galerkin’s method was used to discretize partial differential Eqs. The mine hoisting system was used to the example to analysis the relation between the load, velocity and transverse vibration of rope. The in situ tests were illustrated to evaluate the proposed mathematical model. The results showed that the modeling method can well represent the transverse vibration of rope.
Highly directional emission from few-micron-size elliptical microdisks (2004)

Few-micron-sized elliptically deformed InGaAsP–InP microdisk lasers are fabricated and highly directional emissions are observed along the direction perpendicular to the surface of highest curvature. As the size of the elliptical microdisk is reduced, both the azimuthal angular spreading and the number of lobes become smaller. The improved directionality of the smaller structure is attributed to the enhanced tunneling loss at the high curvature surfaces. The far-field radiation is linearly polarized. Charge-coupled-device images confirmed the existence of strong near-field emission in the vicinity of high curvature surfaces.
Sodium Diffusion in Sodium Tungsten Bronze (1954)

Diffusivity has been measured in single crystals of the metallic sodium tungsten bronze, Na0.78WO3, at 664°C, 752°C, and 832°C. Concentration gradients were established by effusion of sodium from single crystals into a vacuum and were measured by determining the variation in the lattice constant. The diffusivities were calculated by a method which is based upon Fick's first law and which, to the author's knowledge, has not been used previously. The data obtained from several crystals held at constant temperature for varying periods of time gave a family of curves showing the sodium concentration as a function of depth with time as a parameter. From these curves the mass of sodium transferred through a plane parallel to the surface and at any particular depth could be obtained; this mass was plotted as a function of time. The slope of this curve divided by the concentration gradient, both evaluated at the same time and depth, was taken as the diffusivity for the corresponding concentration. The diffusivity of sodium in Na0.78WO3 was found to be represented by the equation D=D0 exp (—ΔH/RT), where D0=0.87 cm2/sec and ΔH=51.8 kcal/mole. In order to calculate the diffusivity it was necessary to determine the coefficients of linear expansion. For Na0.8WO3 the length L at temperature Tc was found to be L=L0[1+(8.81×10−6)Tc−(1.92×10−9)Tc2],where L0 is the length at 0°C and Tc is the temperature in degrees centigrade.
