Presence of lipid hydroperoxide in human plasma. (1985)

Using purified prostaglandin (PG) H synthase, which synthesizes PGG2 and PGH2 from arachidonic acid, we were able to assay for the presence of peroxide activators in biological tissues. This assay system, capable of detecting both hydrogen peroxide (H2O2) and lipid hydroperoxides, detected a significant amount of synthase activator in plasma. Treatment of the active preparations with catalase and glutathione peroxidase showed that the principal activator in normal human plasma was a lipid hydroperoxide rather than H2O2.

Theoretical energy release of thermites, intermetallics, and combustible metals (1998)

Thermite (metal oxide) mixtures, intermetallic reactants, and metal fuels have long been used in pyrotechnic applications. Advantages of these systems typically include high energy density, impact insensitivity, high combustion temperature, and a wide range of gas production. They generally exhibit high temperature stability, and possess insensitive ignition properties. In this paper, the authors review the applications, benefits, and characteristics of thermite mixtures, intermetallic reactants, and metal fuels. Calculated values for reactant density, heat of reaction (per unit mass and per unit volume), and reaction temperature (without and with consideration of phase changes and the variation of specific heat values) are tabulated. These data are ranked in several ways, according to density, heat of reaction, reaction temperature, and gas production.
Reliable Orientation Estimation of Vehicles in High-Resolution Radar Images (2016)

With new generations of high-resolution imaging radars, the orientation of vehicles can be estimated without temporal filtering. This enables time-critical systems to respond even faster. Based on a large data set, this paper compares three generic algorithms for the orientation estimation of a vehicle. An experimental MIMO imaging radar is used to highlight the requirements of a robust algorithm. The well-known orientated bounding box and the so-called L-fit are adapted for radar measurements and compared with a brute-force approach. A quality function selects the best fitted model and is a key factor to minimize alignment errors. Moreover, the reliability of the estimation is evaluated with respect to the aspect angle, the distance to the target, and the number of sensors. An approach to estimate the reliability of the current orientation estimation is introduced. It is shown that the root mean square error of the orientation estimation is 9.77° and 38% smaller compared with the common algorithm. In 50% of the evaluated measurements the orientation estimation error is smaller than 3.73°.
ChemInform Abstract: CHININDENE 3. MITT. DIE AMINO‐ UND HYDROXYMETHYLIERUNG VON BETA‐CHININDAN IN DER STELLUNG 3 (1971)

Abstract Das Chinindan (I) ergibt bei der Mannichreaktion mit Formaldehyd und den sekundären Aminen (III) neben den Mannichverbindungen (IV) eine Methylenverbindung (V), die wahrscheinlich über die Hydroxymethylverbindung (VI) entstanden ist und die sich in Gegenwart von Raney‐Nickel zu dem Methylchinindan (VIII) hydrieren läßt. Wird das Chinindan (I) nur mit Formaldehyd erhitzt, so entsteht nicht die Methylenverbindung (V), sondern die Bishydroxymethylverbindung (VII).
<title>Bragg gratings in ORMOCERs</title> (1997)

Two novel holographic recording media based on silica gel methyl methacrylate (MMA) and hydroxy ethyl methacrylate (HEMA) organically modified ceramics (ORMOCERS) are presented and its holographic properties, inferred from the experimental data, are discussed. The recording of holographic gratings of both low-spatial frequency (50 lp/mm) and high-spatial frequency (1400 lp/mm) in a bulk ORMOCER matrix is reported. The gratings were recorded by UV irradiation-induced photopolymerization of the MMA or HEMA monomers embedded in the silica matrix. The Bragg gratings were successfully recorded by interference of two coherent beams of 351.1 nm wavelength. A linearly polarized He-Ne laser beam (632.8 nm) was used for continuous monitoring of the recording process by measurement of the diffraction efficiency and for enhancement of the grating creation process. High diffraction efficiencies (93%) and low absorption and scattering coefficients were measured during the holographic reconstruction by He-Ne laser beam. The most important holographic parameters of the gratings were inferred from the experimental data: diffraction efficiency, angular selectivity, refraction-index modulation amplitude, spectral sensitivity, the Klein-Cook parameter, and the environmental stability of the gratings.

Reduction of hepatotoxicity of tumor necrosis factor in isolated hepatic perfusion by administration of glucocorticoid as well as lipopolysaccharide. (2000)

We propose new a protocol for IHP as follows: 1. the intradermal administration of LPS for protection against toxicity of TNF, 2. IHP with TNF-SAM2, a mutain of TNF-alpha, having less toxicity than conventional TNF-alpha, and 3. simultaneous perfusion with chemotherapeutic agents such as 5-fluorouracil (5-FU).
LH Release and Ovulation in the Prepuberal Lamb (1972)

Attainment of puberty in ewe lambs is a function of season of birth, breed, age and weight (Hulet, 1968). Foote, Sefidbakht and Madsen (1970) found that the first ovulation in ewe lambs was very seldom accompanied by estrus, however, the hormonal changes responsible for the first ovulation and first estrus are not well documented. A higher gonadotropic potency of the pituitary before puberty with a decrease at puberty has been demonstrated by Mansour (1959). Estrogen has been implicated in the ovulatory release of luteinizing hormone (LH) in mature ewes (Goding et al., 1969; Piper and Foote, 1968), a response which was prevented by concomitant injection of progesterone or by immunization against estradiol-17β in ovariectomized ewes (Scaramuzzi et al., 1971; Caldwell et al., 1970). Pretreatment with estradiol-17β enhanced the occurrence of estrus and ovulation in ewe lambs in response to progestin and pregnant mares serum gonadotropin (PMS) treatments (Bennett and Foote, 1968; Foote and Matthews, 1969; Burfening and Van Horn, 1970).
Color map-based image fusion (2008)

An image fusion system accepts two source images and produces a 'better' fused image. The term 'better' differs from one context to another. In some contexts, it means holding more information. In other contexts, it means getting more accurate results or readings. In general, images hold more than just the color values. Histogram distribution, dynamic range of colors, and color maps are all as valuable as the color values presenting the pictorial information of the image. This paper studies the problems of fusing images from different domains. It proposes a method to extend the fusion algorithms to fuse image properties that define the interpretation of captured images as well.
THE GENERATION OF LONG WAVES IN THE LABORATORY (1980)

It became evident in the experimental aspects of a recent study of the propagation of nonlinear long waves past a step and up a slope that it was important to be able to generate waves which were initially well defined. The investigation dealt with the reflection and transmission of tsunamis past the continental shelf-break, and as such, two simple waves were used to represent certain characteristics of tsunamis: solitary waves and cnoidal waves. (Both of these permanent waves are solutions to the Korteweg-de Vries equation which to a certain order describe the propagation in two dimensions of nonlinear dispersive shallow water waves (see, e.g. Whitham, 1974).) The solitary wave actually can be generated in the laboratory in a simple manner if the wave tank is long enough and wave groups trailing the main wave are unimportant to the study. An example of the resulting waves obtained in the laboratory using a crude generation, procedure is demonstrated by the oscillograph record presented in Figure 1. Six traces are shown: the one at the bottom of the figure describes the time-displacement history of a vertical bulkhead wave generator which is moved by a hydraulic-servo system, the other five are the time variations of the water surface obtained using resistance wave gages spaced at the indicated number of depths downstream from the generator. (In the example presented, the depth of water was 10 cm and the wave plate was moved linearly with time a distance of 10.33 cm in 0.8 sec.) The wave generated and first shown 10 depths downstream appears to qonsist of a large wave followed by a series of oscillatory waves (termed the tail). As would be expected, as the waves propagate, due to the frequency content and the amplitude of the waves, the system separates into a leading wave followed some distance behind by the tail. The lead wave has the characteristic shape of a solitary wave. However, if the oscillatory tail is unacceptable for the type of experiments being conducted, and if it cannot be eliminated or the method of elimination is unacceptable, then a means of generation must be sought which eliminates the trailing waves initially.
Bacteremias and Fungemias in Oncologic Patients With Central Venous Catheters (1982)

Ninety central venous catheters were inserted into 80 patients undergoing therapy for malignant neoplasms. Bacteremia and fungemia occurred in 18 of 41 treatment courses in patients with acute leukemia and in nine of 55 treatment courses in patients with solid tumors and lymphomas. Although gram-negative organisms accounted for nine (33%) cases of infection, the majority of disseminated infections were caused by gram-positive organisms (12 [45%] cases) or fungi (six [22%] cases). Central venous catheters may be helpful in the treatment of patients undergoing intensive therapy with cytotoxic agents, but the shift in-spectrum of infection to gram-positive bacteremias in patients with these catheters compared with patients treated using peripheral vein access must be appreciated.
Studies on the Steroidal Components of Domestic Plants. XL. Constituents of <I>Heloniopsis orientalis</I> (T<SUB>HUNB</SUB>.) C. T<SUB>ANAKA</SUB>.(3) The Structure of Heloniogenin (1962)

A new steroidal sapogenin isolated from Heloniopsis orientalis (THUNB.) C. TANAKA was named “heloniogenin”. The chromic acid oxidation of this sapogenin yielded gentrogenin. Gentrogenin acetate was also obtained with the chromic acid oxidation heloniogenin 3-acetate. Of two isomers derived from gentrogenin with the metal hydride reduction, 3β, 12α-diol was identified with heloniogenin. The structure of heloniogenin was confirmed as 25D-spirost-5-ene-3β, 12α-diol.

Phage display screening without repetitious selection rounds (2011)

Phage display screenings are frequently employed to identify high-affinity peptides or antibodies. Although successful, phage display is a laborious technology and is notorious for identification of false positive hits. To accelerate and improve the selection process, we have employed Illumina next generation sequencing to deeply characterize the Ph.D.-7 M13 peptide phage display library before and after several rounds of biopanning on KS483 osteoblast cells. Sequencing of the naive library after one round of amplification in bacteria identifies propagation advantage as an important source of false positive hits. Most important, our data show that deep sequencing of the phage pool after a first round of biopanning is already sufficient to identify positive phages. Whereas traditional sequencing of a limited number of clones after one or two rounds of selection is uninformative, the required additional rounds of biopanning are associated with the risk of losing promising clones propagating slower than nonbinding phages. Confocal and live cell imaging confirms that our screen successfully selected a peptide with very high binding and uptake in osteoblasts. We conclude that next generation sequencing can significantly empower phage display screenings by accelerating the finding of specific binders and restraining the number of false positive hits.
Concurrent development of radar systems (1994)

Whilst each application of re-engineering has achieved a measure of success in its own right, the need to continuously, and seamlessly, support such initiatives has now become widely accepted in many industries. The paper describes the problems of allowing a functionally based structure to become the dominant force in a business attempting innovative product development and new product introduction. It also outlines the ways in which Siemens Plessey has previously tackled this issue, and is now attempting to provide a basis for sustained improvement. >
Pulmonary oedema and haemoptysis induced by strenuous swimming (1995)

Accumulation of cyclophilin A isoforms in conditioned medium of irradiated breast cancer cells (2012)

Secreted proteins play a key role in cell signaling and communication. We recently showed that ionizing radiations induced a delayed cell death of breast cancer cells, mediated by the death receptor pathways through the expression of soluble forms of "death ligands." Using the same cell model, the objective of our work was the identification of diffusible factors, secreted following cell irradiation, potentially involved in cell death signaling. Differential proteomic analysis of conditioned media using 2DE resulted in detection of numerous spots that were significantly modulated following cell irradiation. The corresponding proteins were identified using MALDI-TOF MS and LC-MS/MS approaches. Interestingly, five isoforms of cyclophilin A were observed as increased in conditioned medium of irradiated cells. These isoforms differed in isoelectric points and in accumulation levels. An increase of cyclophilin A secretion was confirmed by Western blotting of conditioned media of irradiated or radiosentive mammary cells. These isoforms displayed an interesting pattern of protein maturation and post-translational modifications, including an alternating removal of N-terminal methionine, associated with a combination of acetylations and methylations. The role of the protein is discussed in relation with its potential involvement in the mechanisms of intercells relationships and radiosensitivity.
Binocular competition in the control of geniculate cell size depends upon visual cortical N-methyl-D-aspartate receptor activation. (1990)

The lateral geniculate nucleus relays visual information from the retina to cortex. One well-known anatomical consequence of monocular deprivation during early postnatal development is a shrinkage of neurons in the lamina of the lateral geniculate nucleus that receive input from the deprived eye. This is thought to reflect the competition of afferents subserving the two eyes, possibly at the level of the visual cortex. We find that blockade of N-methyl-D-aspartate receptors in kitten visual cortex disrupts this process of binocular competition. These data provide direct evidence that postsynaptic activation of cortical neurons is required for competitive changes in lateral geniculate cell size and suggest a role for N-methyl-D-aspartate receptors in anatomical as well as physiological plasticity in the mammalian visual system.
The Farm Level Effects of Better Access to Information: The Case of Dart (1988)

Abstract In this study, two methods of entering and accessing dairy herd records are compared: the traditional mail-in Dairy Herd Improvement (DHI) system and the Direct Access to Records by Telephone (DART) system, which provides more timely and convenient access to records. An evaluation of DART was carried out using mail survey responses from 117 DART users and telephone surveys of 40 randomly selected users. Results indicate that DART users are generally satisfied with the system and feel that it improves their herd management. Variations in use of the DART system by DART users are explained by herd, cost, and management variables. DART users and comparable non-DART, DHI users are compared with respect to gains in herd production efficiency. Results indicate that DART users made somewhat better gains in most efficiency measures but that the differences were generally not statistically significant.

Binding of pea cytochrome f to the inner membrane of Escherichia coli requires the bacterial secA gene product. (1985)

Various sequences from the 5' end of the pea chloroplast gene for cytochrome f have been fused in the correct reading frame with lacZ, and the cellular location of the hybrid polypeptides in Escherichia coli has been examined. Hybrid polypeptides containing N-terminal parts of cytochrome f are located in the cytoplasmic membrane of E. coli. Membrane localization is most efficient when the intact signal sequence of cytochrome f is present at the N-terminal end of the fusion proteins. Fusion within the signal sequence, so that the processing site is absent, reduces the efficiency of membrane binding. Membrane insertion of fusion proteins containing signal sequences is prevented in a temperature-sensitive secA strain at the nonpermissive temperature and the hybrid proteins accumulate in the cytoplasm. This indicates that specific recognition of the chloroplast signal sequence occurs in the bacterial secretory pathway.
