A myocardial cytotoxic process is involved in the cardiac dysfunction of meningococcal septic shock (2000)

The elevated serum concentrations of cTnI indicate that myocardial cell death is occurring in meningococcal septicemia. The relationship between cTnI and markers of myocardial function suggest that the cell death may have a role in the pathogenesis of myocardial dysfunction in meningococcal septicemia. Elucidation of the mechanism responsible for myocardial injury may lead to the development of therapeutic interventions to prevent or limit this cardiac damage.
Cellular Mechanisms in the Response of the Arterial Wall to Injury and Repair (1989)

This synopsis emphasizes the inappropriateness of a "single stimulus-single response" approach in understanding the response of the arterial wall to injury and repair. The outcome of any injurious stimulus is a series of interactive cascades among the endogenous and exogenous cellular and non-cellular components of the arterial wall, and the cellular and non-cellular elements of the blood. Both genetic and hemodynamic factors can further influence this response. The more prominent of the cellular and non-cellular components have been discussed. These include: 1) the vascular endothelium, its dynamic interaction with macromolecules and formed elements of the blood, its role in the transport of plasma proteins, its influence on the function of arterial smooth muscle cells and the recruitment of blood-born monocytes; 2) the arterial smooth muscle cell, its role in the vasomotor function of the artery wall, arterial repair and reconstruction, metabolism of lipids and the secretion of cytokines regulating monocyte recruitment; 3) the mononuclear phagocyte, its role in arterial debridement, metabolism of modified LDLs, a precursor of the cholesteryl ester-rich foam cell, and the secretion of neutral hydrolases, bioactive lipids and cytokines; 4) lymphocytes, as mediators of the inflammatory response and possible autoimmune reactions; 5) platelets, their roles in hemostasis, thrombosis, atherogenesis, and the repair process and 6) plasma LDLs, their oxidative modification by cells of the vessel wall and their roles in the injury process. The interactive processes among arterial and circulating components in both injury and repair is emphasized.
Structure-aware shape processing (2013)

Shape structure is about the arrangement and relations between shape parts. Structure-aware shape processing goes beyond local geometry and low level processing, and analyzes and processes shapes at a high level. It focuses more on the global inter and intra semantic relations among the parts of shape rather than on their local geometry.
Language Issues and Programming Techniques in BinProlog. (1993)

Placenta forms as a momentary organ inside the uterus with a slew of activities only when the woman is pregnant. It is a discoid-shaped hybrid structure consisting of maternal and embryonic components. It develops in the mesometrial side of the uterus following blastocyst implantation to keep the two genetically different entities, the mother and embryo, separated but connected. The beginning and progression of placental formation and development following blastocyst implantation coincides with the chronological developmental stages of the embryo. It gradually acquires the ability to perform the vascular, respiratory, hepatic, renal, endocrine, gastrointestinal, immune, and physical barrier functions synchronously that are vital for fetal development, growth, and safety inside the maternal environment. The uterus ejects the placenta when its embryonic growth and survival supportive roles are finished; that is usually the birth of the baby. Despite its irreplaceable role in fetal development and survival over the post-implantation progression of pregnancy, it still remains unclear how it forms, matures, performs all of its activities, and starts to fail functioning. Thus, a detailed understanding about normal developmental, structural, and functional aspects of the placenta may lead to avoid pregnancy problems that arise with the placenta.
Ultrastructural identification of the mouse basophil (1982)

We have established the identity of the basophilic leukocyte in the mouse. Previously undefined by electron microscopy, mouse basophils ultrastructurally resemble those of other mammalian species and are readily distin guishable from other granulocytes, lymphocytes, macrophages, and mast cells.
Organophosphazene Compounds as Modifiers of Organic Polymers: Syntheses and Characterization Aspects (1999)

Abstract The synthesis of new types of organic-inorganic polymers (urethane-phosphazene polymers) from cyclotriphosphazenes and the use of polyorganophosphazenes in the surface modification of organic polymers such as Poly(viny alcohol) (PVA) and poly(ethylene-co-vinyl alcohol) (EVOH) have been investigated. In both cases, the goal of the studies was to combine the usual advantages of the organic polymers and some of the properties of phosphazenes, namely mechanical properties, thermal stability, light-heat and fire resistance by incorporating them into the carbon chain or by superficial grafting.

Photoluminescence and energy transfer behavior of narrow band red light emitting Li<sub>3</sub>Ba<sub>2</sub>Tb<sub>3</sub>(MoO<sub>4</sub>)<sub>8</sub>:Eu<sup>3+</sup> (2017)

This work concerns the polycrystalline red emitting solid state compound Li<sub>3</sub>Ba<sub>2</sub>(Tb<sub>1-x</sub>Eu<sub>x</sub>)<sub>3</sub>(MoO<sub>4</sub>)<sub>8</sub>, from which a series of powder samples was prepared by a conventional solid-state reaction. The phase formation of the samples was investigated by X-ray diffraction which revealed the formation of a solid solution without a miscibility gap. Photoluminescence (PL) spectra and decay curves were recorded as a function of Tb<sup>3+</sup> and Eu<sup>3+</sup> concentration and temperature. It turned out that the external quantum efficiency of Eu<sup>3+</sup> photoluminescence is between 30 and 80%, while the highest quantum yield is achieved for about 60% Tb<sup>3+</sup>. An increase of emission intensity can be realized by co-doping of Eu<sup>3+</sup> and Tb<sup>3+</sup>. Moreover, the emission has a luminous efficacy of 275 lm W<sub>opt</sub><sup>-1</sup> which is a distinct advantage over the widely applied Mn<sup>4+</sup> activated fluorides. The time dependent photoluminescence as a function of Tb<sup>3+</sup> concentration demonstrates the presence of an efficient energy transfer from Tb<sup>3+</sup> to Eu<sup>3+</sup>. Temperature dependent PL measurements revealed that Li<sub>3</sub>Ba<sub>2</sub>(Tb<sub>1-x</sub>Eu<sub>x</sub>)<sub>3</sub>(MoO<sub>4</sub>)<sub>8</sub> loses just 20% of PL efficiency up to 400 K. Therefore, the investigated phosphors are attractive for application in pcLEDs. It is finally demonstrated that the application of a Eu<sup>3+</sup>/Tb<sup>3+</sup> co-doped ceramic disc is useful for the colour conversion of a blue emitting LED with a higher conversion rate compared to Li<sub>3</sub>Ba<sub>2</sub>(La<sub>1-x</sub>Eu<sub>x</sub>)<sub>3</sub>(MoO<sub>4</sub>)<sub>8</sub>.
A CMOS-3D reconfigurable architecture with in-pixel processing for feature detectors (2012)

This paper introduces a two-tier CMOS-3D architecture for generation of Gaussian pyramids, detection of extrema, and calculation of spatial derivatives in an image. Such tasks are included in modern feature detectors, which in turn can be used for operations like object detection, image registration or tracking. The top tier of the architecture contains the image acquisition circuits in an array of 320 × 240 active photodiode sensors (APS) driving a smaller array of 160 × 120 analog processors for low-level image processing. The top tier comprises in-pixel Correlated Double Sampling (CDS), a switched-capacitor network for Gaussian pyramid generation, analog memories and a comparator for in-pixel Analog to Digital Converter (ADC). The reuse of circuits for different functions permits to have a small area for every pixel. The bottom tier of the architecture contains a frame buffer with a set of registers acting as a frame-buffer with a one-to-one correspondence with the analog processors in the top tier, the digital circuitry necessary for the extrema detection and the calculation of the first and second spatial derivatives in the image, as well as Harris and Hessian point detectors. For the time being, a behavioral model of the first tier including mismatch and feedthrough and charge injection errors is discussed. Also, a VHDL model for the bottom tier is addressed. The two-tier architecture is conceived for its implementation on the 130 nm CMOS-3D technology from Tezzaron. A companion chip will perform the higher-level operations as well as communications. In this technology an area of 300 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> per analog processor has been estimated. The architecture proposed for pyramid generation lets a frame rate of 180 frames/s for an ADC conversion time of 120 μs. The architecture has been proved with object detection for a given feature detector.
Protective role of R-spondin3 in mesenteric ischemia/reperfusion induced tissue injury (54.11) (2012)

Abstract Ischemia reperfusion (I/R) injury represents a leading cause of morbidity and mortality. R-spondins, acknowledged as ligands of Wnt pathways, demonstrate their physiological role as mitogens, morphogens, stem cell factors, and wound healing agents in various development and disease models. We asked whether these proteins could prevent inflammation-associated tissue damage in ischemic disorders. C57BL/6J mice were pretreated with vehicle or R-spondin3 (R-spo3) before inducing mesenteric I/R for 30/180 min. At the end of reperfusion, intestinal tissues were harvested for different experimental analysis. Treatment with R-spo3 significantly decreased local intestinal injury. mRNA and protein analyses revealed that this effect was achieved through the modulation of the expression of pro-inflammatory cytokines (IL-6, TNFα and COX2) and deposition of IgM and complement. The decreased levels of IgM on tissues correlated with the reduced vascular leakage in the intestine of R-spo3 treated mice. Further we determined the effect of R-spo3 on endothelial barrier function in vitro using HUVECs and FITC-dextran (500kDa). R-spo3 pretreated groups showed significant reduction in histamine-enhanced FITC-dextran permeability of endothelial monolayer. Our results demonstrate that R-spo3 mitigates I/R-induced local tissue injury by preventing vascular leakage and decreasing the local inflammatory response. These findings confer the protective effects of R-spondin3 in I/R-related tissue damage.
725 Dynamics of a Curved Fluid-Conveying Pipe Taking the Gravity Force into Consideration (2004)

This paper deals with the static shape and dynamics of a curved fluid-conveying pipe, which is hanging horizontally and is supported at both ends. First, the effects of the gravity force acting on the pipe, the tension at the supported ends and the fluid force of an internal flow on the static equilibrium state of the flexible curved pipe are clarified theoretically. Second, the forced in-plane vibration of the curved pipe due to the pulsating component of an internal flow is examined theoretically. Finally, the experiments were conducted with a silicon rubber tube conveying water.
Sketches of Otohistory (2008)

The Sketches of Otohistory paint a fascinating picture of otology from its incipiency in the ancient circum-Mediterranean civilizations, through the 19th-century rise of aural surgery and inner ear anatomy, to the modern world. Although scholarly researched, the Sketches of Otohistory are not an accumulation of dry facts and dates. Rather, they are
The Transfer RNA Methylases of Human Lymphocytes. I. Induction by PHA in Normal Lymphocytes (1971)

Abstract Assays were performed that measured both the rate and extent (or total capacity) of transfer RNA methylases in extracts of lymphocytes cultured in the presence and absence of phytohemagglutinin (PHA). The tRNA methylases of human peripheral blood lymphocytes undergoing blastogenesis in culture with PHA had a five- to sixfold increase in rate and a three- to sevenfold increase in extent of methylation of heterologous tRNA. These data suggest that PHA transformed lymphocytes not only contain elevated levels of tRNA methylases, but that the increase includes qualitatively different enzymes from those found in normal peripheral blood lymphocytes. Experiments in which lymphocytes were incubated for various times with PHA revealed that tRNA methylase induction occurred late in or after DNA synthesis and after morphologic transformation, but prior to mitosis. Rate and extent of tRNA methylation increased simultaneously. PHA induction of tRNA methylase activity was dependent on the synthesis of new RNA in lymphocytes cultured from 40 to 45 hours. The increase was not due to different levels of inhibitors or activators or preferential degradation of reaction components. The data suggest that quantitative and qualitative changes occur in the tRNA methylases of the normal human peripheral blood lymphocyte stimulated by PHA to undergo transition to an undifferentiated cell "in cycle." The possible significance of these findings to control of protein synthesis in PHA transformed lymphocytes is discussed.

Patients with either a synchronous or latent diagnosis of RCC survived greater than 6 months from the time of presentation. Initial Furhman grade, Tokuhashi score, and MSKCC/Motzer can be useful tools in informing patient-specific prognosis for those with metastatic RCC of the spine.
Differential cryptanalysis of Q (2002)

Q is a block cipher submitted as a cmdidate to the NESSIE project by Leslie McBride. The submission document of Q describes 12 one-round iterative chm&apos;acteristics with probability 2-18 each. On 7 rounds these chm&apos;acteristics have probability 2-12e md the author of Q claims that they m&apos;e the best 7-round chm&apos;acteristics. We find additional one-round chm&apos;acteristics that cm be extended to more rounds. We also combine the chm&apos;acteristics into differentials. We present several differential attacks on the full cipher. Our best attack on the full Q with 128-bit keys uses 215 chosen plaintexts md has a complexity of 277 encryptions. Our best attack on the full Q with lm&apos;ger key sizes uses 2125 chosen ciphertexts, md has a complexity of 29e for 192-bit keys md 2128 for 256-bit keys.
Heterogeneity of Stimulant Dependence: A National Drug Abuse Treatment Clinical Trials Network Study (2009)

We investigated the presence of DSM-IV subtyping for dependence on cocaine and amphetamines (with versus without physical dependence) among outpatient stimulant users enrolled in a multisite study of the Clinical Trials Network (CTN). Three mutually exclusive groups were identified: primary cocaine users (n = 287), primary amphetamine users (n = 99), and dual users (cocaine and amphetamines; n = 29). Distinct subtypes were examined with latent class and logistic regression procedures. Cocaine users were distinct from amphetamine users in age and race/ethnicity. There were four distinct classes of primary cocaine users: non-dependence (15%), compulsive use (14%), tolerance and compulsive use (15%), and physiological dependence (tolerance, withdrawal, and compulsive use; 56%). Three distinct classes of primary amphetamine users were identified: non-dependence (11%), intermediate physiological dependence (31%), and physiological dependence (58%). Regardless of stimulants used, most female users were in the most severe or the physiological dependence group. These results lend support for subtyping dependence in the emerging DSM-V.

Interrogating the Intramolecular Charge-Transfer State of a Julolidine−Anthracene Donor−Acceptor Molecule with Femtosecond Stimulated Raman Spectroscopy (2009)

The nature of the lowest-energy charge-transfer (CT) excited state of the donor−acceptor molecule, 3,5-dimethyl-4-(9-anthracenyl)julolidine (DMJ−An) is investigated using femtosecond stimulated Raman spectroscopy. Transient Raman spectra are presented with subpicosecond time resolution, and peaks are assigned based on the published Raman modes of the reference molecule phenyl anthracene. The results indicate that the CT excited state is dominated by a fully charge separated radical ion pair state with minimal contribution from the local anthracene π−π* state.
Linearized field theory of a dielectric-loaded helix traveling wave tube amplifier (1996)

A linearized relativistic field theory of a helix traveling wave tube (TWT) is presented for a configuration where either a thin annular beam or a solid beam propagates through a sheath helix enclosed within a loss-free wall in which the gap between the helix and the outer wall is filled with a dielectric. A linear analysis of the interaction is solved subject to the boundary conditions imposed by the beam, helix, and wall. In the case of the annular beam, the electrons are assumed to be strongly magnetized. In contrast, the effect of variations in the axial magnetic field are included in the electron dynamics for the solid beam analysis. Determinantal dispersion equations are obtained for the azimuthally symmetric modes which implicitly includes beam space-charge effects without recourse to a heuristic model of the space-charge field. Numerical solutions of the dispersion equations are discussed and compared with experiments.
c-myc expression is controlled by the mitogenic cAMP-cascade in thyrocytes (1996)

In dog thyroid epithelial cells in primary culture, thyrotropin (TSH), acting through cAMP, induces proliferation and differentiation expression, whereas epidermal growth factor (EGF) and phorbol esters induce proliferation and dedifferentiation. In these cells, we have detailed the regulation by cAMP of the c-myc protooncogene mRNA and protein. The cAMP signaling pathway induces a biphasic increase of c-myc mRNA and protein. c-Myc protein accumulation follows the abundance and kinetics of its mRNA expression. Using in vitro elongation of nascent transcripts to measure transcription and actinomycin D (AcD) chase experiments to study mRNA stability, we have shown that in the first phase cAMP releases a transcriptional elongation block. No modification of transcriptional initiation was observed. After 30 min of treatment with TSH, c-myc mRNA was also stabilized. During the second phase, cAMP stabilization of the mRNA disappears and transcription is again shut off. Thus, in a tissue in which it stimulates proliferation and specific gene expression, cAMP regulates biphasically c-myc expression by mechanisms operating at the transcriptional and posttranscriptional levels.
Magnetic-field effects in transitions of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>X</mml:mi></mml:math>Li molecules (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>X</mml:mi></mml:math>: even isotopes of group II atoms) (2011)

We analyze the Zeeman shift in the $(v,N)=(0,0)\ensuremath{\rightarrow}(1,0)$ transition frequency of $X$ Li molecules ($X$: even isotopes of group II atoms), which is of interest in metrology. The Zeeman shift in the transition frequency between stretching states is found to be less than 1 mHz with a magnetic field of 1 G. $X$ ${}^{6}$Li molecules are more advantageous than $X$ ${}^{7}$Li molecules for measuring the transition frequency without the Zeeman shift because of the smaller $g$ factor of the Li nuclear spin.
Bromodeoxyuridine induced variations in the level of alkaline phosphatase in several human heteroploid cell lines (1976)

The level of alkaline phosphatase in a number of established cell lines of human origin can be modified by exposure to non-lethal concentrations of bromodeoxyuridine (BRdU). In the several cell lines examined an inverse relationship between amount of induction and constitutive level of the enzyme was observed. Thus, the H.Ep 2 line, which had the highest basal level of enzyme, was reversibly repressed following exposure to the drug, whereas other cell lines with relatively low constitutive enzyme levels were induced to a maximum of 10-fold following exposure. Initiation of induction required from 24 to 48 hours, and as short an exposure ("pulse") as five hours was sufficient to produce induction. Exposure to visible light had no effect upon the repression of alkaline phosphatase in H.Ep 2 by BRdU. Induction did not occur in non-dividing, serum starved cells. The time course of induction by BRdU and hydrocortisone was similar, and simultaneous exposure of the cells to both agents resulted in no greater induction than that observed with either drug alone. Experiments utilizing mitomycin C yielded significant induction in the presence of this agent alone, and somewhat less induction when both mitomycin C and BRdU were added simultaneously. These results suggest that DNA synthesis is required for BRdU were added simultaneously. These results suggest that DNA synthesis is required for BRdU-mediated induction of alkaline phosphatase.
