The Effect of Auto‐Transfusion of “Work‐Blood” on the Pulmonary Ventilation (1950)

Summary. Experiments were carried out in which blood was trapped in the legs by means of pneumatic cuffs immediately after 10 minutes of heavy work (1,340 mkg per minute) and not released until 15 minutes after cessation of work. The effect of this auto‐transfusion of “work blood” was a pronounced increase in the pulmonary ventilation, which prior to the release had returned to a value not much above the resting value. Control experiments showed that this increase only to a minor degree was caused by the concomitant transitory changes in alveolar CO 2 pressure and arterial blood pressure. Breathing of pure oxygen diminished the increase in ventilation caused by the auto‐transfusion considerably. The results from these experiments, therefore, are in good agreement with the conclusion arrived at in earlier experiments, viz. that the blood during heavy work contains specific substances produced under anaerobic conditions in the working muscles and with a pronounced stimulatory effect on the ventilation.

Direct Interaction of <i>Arabidopsis</i> Cryptochromes with COP1 in Light Control Development (2001)

Arabidopsis seedling photomorphogenesis involves two antagonistically acting components, COP1 and HY5. COP1 specifically targets HY5 for degradation via the 26S proteasome in the dark through their direct physical interaction. Little is known regarding how light signals perceived by photoreceptors are transduced to regulate COP1. Arabidopsis has two related cryptochromes (cry1 and cry2) mediating various blue/ultraviolet-A light responses. Here we show that both photoactivated cryptochromes repress COP1 activity through a direct protein-protein contact and that this direct regulation is primarily responsible for the cryptochrome-mediated blue light regulation of seedling photomorphogenic development and genome expression profile.
Fabrication and characterization of microwave immunosensors based on organic semiconductors with nanogold-labeled antibody (2008)

Microelectronic biosensors hold great promise for rapid, sensitive and specific in vitro point-of-care immunodiagnostics. In particular, sensors fabricated using organic semiconductors have attractive advantages-such as ease of manufacture and low cost-in the design and implementation of such devices. Furthermore, immobilization of an antibody or protein antigen as a biorecognition element onto an organic semiconducting film allows for direct transduction of biomolecular binding events into an electronic signal which is readily measured and processed. In previous work, we have demonstrated that an antigen can be bound to organic semiconducting films while retaining enzymatic activity after immobilization. The present work considers organic semiconducting films which are spin-cast onto an interdigitated electrode; antibodies labeled with gold-nanoparticles are applied to the organic semiconducting film and serve as a biorecognition element. The sensor geometry includes a high-frequency coplanar waveguide contact metallization to facilitate direct measurement using microwave wafer probes. Equivalent circuit models are derived from microwave measurements over the frequency range 0.3 MHz to 8.5 GHz.
Synthesis of Nanocrystalline  VO 2 and Its Electrochemical Behavior in Lithium Batteries (1997)

Nanocrystalline having a metastable shear structure, designated as (B), has been synthesized by a simple chemical method. The procedure involves a reduction of aqueous potassium vanadate solution with potassium borohydride around pH 4. The sample has been characterized by x‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, and transmission electron microscopy. The metastable (B) begins to transform irreversibly to the more stable monoclinic rutile around 350°C and the transformation is complete around 500°C. (B) exhibits a maximum reversible capacity of about 320 mAh/g in the range 4 to 1 V in lithium cells. A good capacity retention on cycling makes it an attractive cathode for rechargeable lithium cells. In addition, the excellent cyclability without any capacity decline around an intermediate 2.5 V range may become particularly useful for the recently suggested aqueous lithium‐ion cells consisting of (B) anode and cathode.
Studies with the Ruthenacarborane Complex [Ru(CO)(PPh<sub>3</sub>)(THF)(η<sup>5</sup>-7,8-C<sub>2</sub>B<sub>9</sub>H<sub>11</sub>)]:  Reactions with Terminal Alkynes (2000)

The syntheses of the complexes [Y][RuX(L)(PPh3)(η5-7,8-C2B9H11)] (X = Cl, Y = K(18-crown-6), L = CO (1), PPh3 (2); X = I, Y = NEt4, L = CO (3)) are reported, and the structure of 3 has been established by an X-ray diffraction study. The anion adopts the “piano stool” structure with the ruthenium atom η5-coordinated on one side by a nido-7,8-C2B9H11 group and on the other by the CO, PPh3, and I ligands. Treatment of 1 with TlPF6 in THF (tetrahydrofuran) affords solutions of the labile species [Ru(THF)(CO)(PPh3)(η5-7,8-C2B9H11)] (5), which readily react with a 3-fold excess of the monosubstituted alkynes RC⋮CH (R = Ph, But, SiMe3). The product from PhC⋮CH is [Ru(CO)(PPh3)(η2: η5-9-(E)-C(H)C(H)Ph-7,8-C2B9H10)] (8), the structure of which was determined by X-ray crystallography. The metal atom is η5-coordinated by the open face of the nido-7,8-C2B9 cage and also η2-coordinated by the CC bond of the E-C(H)C(H)Ph group, the latter being attached to a boron atom in an α-site with respect to the carbons of the ring ligating the ruthenium. Reaction between 5 and ButC⋮CH gives [Ru(CO)(PPh3)(η2: η5-9-(E)-C(H)C(H)But-10-(E)-C(H)C(H)But-7,8-C2B9H9)] (9). The η2 bonding mode of the 9-(E)-C(H)C(H)But group to the metal is displaced in reactions with PMe3, CNBut, and CO, yielding the species [Ru(CO)(PPh3)(L)(η5-9,10-{(E)-C(H)C(H)But}2-7,8-C2B9H9)] (L = PMe3 (10), CNBut (11), CO (12)). The alkyne Me3SiC⋮CH reacts with 5 in the presence of traces of moisture to give [Ru(CO)(PPh3)(η2: η5-9-C(H)CH2-7,8-C2B9H10)] (13), having a molecular structure closely related to that of 8, as confirmed by an X-ray diffraction study. Compound 13 reacts with CNBut to afford [Ru(CO)(PPh3)(CNBut)(η5-9-C(H)CH2-7,8-C2B9H10)] (14), studied by X-ray diffraction, and with PMe3 to give the ylide complex [Ru(CO)(PPh3)(σ: η5-9-C(H)(PMe3)CH2-7,8-C2B9H10)] (15). The NMR data (1H, 13C{1H}, 11B{1H}) are reported and discussed.
Erythropoiesis in vitro: enhancement by neuraminidase (1981)

Neuraminidase treatment of human fetal liver or adult marrow cells prior to culture results in an increased number of erythroid colonies and bursts. No increase occurs in the number of nonerythroid colonies. The number of bursts having more than eight subunits is increased preferentially. Individual burst subunits are also enlarged. Neuraminidase-treated cells yield erythroid bursts when cultured in concentrations of erythropoietin insufficient to produce bursts from untreated cells. It is proposed that (1) neuraminidase treatment of adult and fetal cell mixtures specifically stimulates differentiation of erythroid precursors, (2) the preferential stimulation of erythroid bursts having many subunits suggests a preferential susceptibility of more primitive BFU-Es, and (3) neuraminidase treatment enhances the response of erythroid precursors to erythropoietin.
Atmospheric measurements of C n<sup>2</sup>and comparisons between atmospheric profiler and aircraft anemometer measurements for clear, daytime conditions (1994)

A joint radar/aircraft optical turbulence measurement is discussed. The joint measurement was made over White Sands, New Mexico with a KC135E aircraft equipped with fiber film temperature probes and a ground-based atmospheric profiler. General meteorological conditions were such that the turbulence on the day of the experiment was fairly weak. Emphasis was placed on the 36,000 ft to 42,000 ft altitude regime. Results showed good agreement between the atmospheric profiler and the aircraft-based measurements.
HINDERED ROTATION AND TRANSLATION OF CHAIN $MOLECULES^{*}$ (1958)

“The lowest-frequency modes of chain molecules in a gas have zero frequency, corresponding to free rotation and translation. In liquids and solids, these modes are inhibited by intermolecular forces and become low-frequency vibrations. These vibrations have been analyzed both classically and quantum-mechanically, assuming for each degree of freedom a one-term potential function with arbitrary exponent. Even if the intermolecular forces are assumed to be linear, some of the vibrations are non-linear, so that the resulting bands have temperature-dependent frequencies and strong overtones. The temperature dependence determines the proper exponent in the appropriate term of the potential function, since the frequency varies as the (n-2)/2n power of the absolute temperature, where n is the exponent in the potential function and is not necessarily integral. For typical hydrogen-bonded polymers with one bond per repeating unit, the theory predicts infrared and Raman bands at frequencies below about $100 cm^{-1}$, some of which will have different temperature dependence than others, to aid in assignment. The greater the temperature dependence, the stronger the overtones, and the odd overtones should be particularly strong.”
Taxol-Lipid Interactions: Taxol-Dependent Effects on the Physical Properties of Model Membranes (1994)

Taxol (paclitaxel) is a diterpenoid anticancer agent undergoing intensive human clinical evaluation. The poor aqueous solubility of taxol necessitates administration in excipients causing a variety of adverse effects, including anaphylactoid hypersensitivity reactions. Recently, taxol has been formulated in better-tolerated drug carriers such as liposomes. We investigated the conformation of taxol and the interaction of taxol with dipalmitoylphosphatidylcholine (DPPC) liposomes using fluorescence, circular dichroism, differential scanning calorimetry, fluorescence polarization, and X-ray diffraction. The conformation of taxol in DPPC membranes was similar to that observed in nonpolar solvents such as chloroform. Taxol was found to partition into the bilayer, perturbing the hydrocarbon chain conformation. The taxol C13 side chain was found to be fluorescent, and it displays an environment-sensitive shift in emission spectrum; taxol fluorescence was used to confirm the insertion of the drug into the bilayer. Taxol induces a broadening of the DPPC phase transition, and the location of the drug in the bilayer depends on drug concentration. Incorporation of taxol affects other physical properties of the bilayer such as the lipid order parameter, and this fluidizing effect was also observed upon incorporation of taxol in biological membranes isolated from basolateral plasma membranes of rat liver. These studies demonstrate that taxol incorporated into liposomes penetrates into the acyl chain domain of the bilayer and alters the physical properties of both artificial and biological membranes.
<title>UV spectra from the sun and the moon and geophysical and biological applications</title> (1993)

Quantitative spectral, solar UV measurements are introduced together with lunar spectral measurements in arbitrary units. Meteorological factors have a more pronounced effect on the UV irradiance than the ozone layer, and the ozone layer has an increasing attenuation effect towards higher latitudes. Coordinated biological and spectral lunar observations are outlined.

Nandrolone abuse decreases anxiety and impairs memory in rats via central androgenic receptors (2008)

Anabolic androgenic steroids (AASs) affect areas of the central nervous system, which are involved in emotional and cognitive responses such as sexuality, anxiety, and memory. In the present study we imitated the abuse of AASs by administering high doses of the AAS nandrolone decanoate (ND) to rats. Thereafter rats were exposed to an elevated plus-maze and an olfactory social memory test to evaluate their anxiety-like and cognitive behaviour. To reveal whether these emotional and cognitive changes evoked by ND were caused via direct activation of androgenic receptors (ARs) in the brain, the AR antagonist flutamide (FL) was administered intracerebroventricularly (i.c.v.). Male rats were randomly divided in four groups, one group received 15 mg/kg ND subcutaneously, once daily for 6 wk (ND group). In the second group, in addition to ND, a daily dose of 5 microg FL was injected i.c.v. also for 6 wk (ND+FL group). The third group of rats received only FL and in the control group the vehicle was injected. The ND group clearly spent more time investigating the open arms in the maze test and recognizing the juvenile during the olfactory social memory test in comparison to the control group. In the ND+FL group rats showed similar emotional behaviour and cognitive ability to that of the control group. Injection of FL alone did not affect either anxiety or memory. These results indicate that repeated, high-dose administration of ND decreases anxiety and impairs memory in rats via direct activation of central ARs.
Honeywell Systems and Research Center 3660 Technology Drive (1988)

A new approach for landmark recognition based on the perception, reasoning, action, and expectation (PREACTE) paradigm is presented for the navigation of autonomous mobile robots. PREACTE uses expectations to predict the appearance and disappearance of objects, thereby reducing computational complexity and locational uncertainty. It uses an innovative concept called dynamic model matching (DMM), which is based on the automatic generation of landmark description at different ranges and aspect angles and uses explicit knowledge about maps and landmarks. Map information is used to generate an expected site model (ESM) for search delimitation, given the location and velocity of the mobile robot. The landmark recognition vision system generates 2-D and 3-D scene models from the observed scene. The ESM hypotheses are verified by matching them to the image model. Experimental results that verify the performance of the PREACTE and DMM algorithms for real imagery are also presented.
A numerical solution of the layered media Green's function for the MPIE in the time domain (2003)

Layered media Green's functions in the frequency domain have been extensively studied previously. Interest has increased in the evaluation of the layered media Green's functions in the time domain, to be subsequently used for time domain integral equations (TDIEs). This is because of critical time-domain applications including the analysis of transients in high speed digital interconnects and for analyzing wideband microstrip antennas. In using time domain layered Green's functions in conjuction with TDIEs, it is necessary to compute the layered medium Green's function for many source-to-field distances /spl rho/ and time intervals t. In this paper, a numerical solution of the layered media Green's function in the time domain for the mixed potential integral equation (MPIE) is reported. The particular case where the source and field points are on the top layer is presented. The method is applicable to multi-layered structures and to both lossless and lossy media. The technique also computes the Green's function for many /spl rho/ and t values simultaneously.
Theory of a Scalable Electron-Spin Based Quantum Network Inside a Photonic Crystal (2010)

We review our theoretical proposal on producing a scalable quantum network inside a photonic crystal. The qubits are represented by electron spins in quantum dots, each embedded inside a nanocavity that is produced by a defect in the photonic crystal. The coupling between the qubits is governed by single photons that are guided through waveguides in the photonic crystal, thereby interacting with the quantum dots by means of the conditional single-photon Faraday rotation, which provides the basic method to entangle single spins with single photons. Unlike other schemes using virtual photons, our scheme makes use of real single photons that produce the spin entanglement. Therefore all the spin-photon interactions can be performed locally at each site of a quantum dot, which is a key ingredient for making our quantum network scalable.

Characterizing Nanoscale Topography of the Aortic Heart Valve Basement Membrane for Tissue Engineering Heart Valve Scaffold Design (2006)

A fully effective prosthetic heart valve has not yet been developed.A successful tissue-engineered valve prosthetic must contain a scaffold that fully supports valve endothelial cell function.Recently, topographic features of scaffolds have been shown to influence the behavior of a variety of cell types and should be considered in rational scaffold design and fabrication.The basement membrane of the aortic valve endothelium provides important parameters for tissue engineering scaffold design.This study presents a quantitative characterization of the topographic features of the native aortic valve endothelial basement membrane; topographical features were measured, and quantitative data were generated using scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM), and light microscopy.Optimal conditions for basement membrane isolation were established.Histological, immunohistochemical, and TEM analyses following decellularization confirmed basement membrane integrity.SEM and AFM photomicrographs of isolated basement membrane were captured and quantitatively analyzed.The basement membrane of the aortic valve has a rich, feltlike, 3-D nanoscale topography, consisting of pores, fibers, and elevations.All features measured were in the sub-100 nm range.No statistical difference was found between the fibrosal and ventricular surfaces of the cusp.These data provide a rational starting point for the design of
Long‐term clinical outcomes following treatment of childhood craniopharyngioma (2010)
