    Wilms' tumor gene (WT1) expression in lung cancer, colon cancer and glioblastoma cell lines compared to freshly isolated tumor specimens (2000)
    Springer
    Journal of cancer research and clinical oncology 126 (2000), S. 226-232

    Notes: Abstract The Wilms' tumor gene (WT1) encodes a transcriptional regulator involved in growth and differentiation of various tissue types. A continuous over-expression of WT1 was found in leukemic blasts, thus suggesting an oncogenic function. Solid cancer entities have also been described as expressing WT1. We systematically analyzed WT1 expression in small-cell and non-small-cell lung cancer, colon cancer and glioblastoma patients and in the respective tumor cell lines. Using reverse transcription/polymerase chain reaction, we found WT1 expression in glioblastoma (5 of 8), lung (5 of 11), and colon cancer (5 of 15) cell lines. While WT1 was expressed in only 1 of 12 lung cancer and 1 of 5 glioblastoma specimens, it was not detected in colon cancer or macroscopically tumor-free colon and lung tissue. In addition, HT29 colon cancer cells showed a loss of WT1 expression when grown to confluence or induced to differentiate by sodium butyrate. From this evidence, testing for WT1 expression is not clinically relevant for colon cancer, lung cancer, or glioblastoma patients. WT1 expression in cancer cell lines can probably be attributed to optimized in vitro growth conditions.

    Rapid movements with reversals in direction (1988)

    ISSN: 1432-1106
    Keywords: Rapid arm movements ; Motor programs

    Topics: Medicine
    Notes: Summary Transformations of the underlying movement control of rapid sequential (reversal) responses were examined as the movement amplitude (Experiment 1) and moment of inertia (Experiment 2) were altered, with constant movement time. Increases in amplitude and inertia were both met by sharply increased joint torques with a constant temporal structure, suggesting that the alterations may have been governed by a single gain parameter. The durations of various EMG bursts were essentially constant across changes in inertia, supporting a model in which the output of a fixed temporal representation is amplified to alter joint torques. The EMG amplitudes increased greatly with both amplitude and load. However, the fact that the EMG durations increased systematically with increases in distance provided difficulties for this model of amplitude control. The data suggest an economy in motor control in simple agravitational movements, whereby relatively simple transformations of an underlying representation can accomodate large changes in movement amplitude and moment of inertia.

    Notes: Summary Modifications to the underlying motor control of rapid reversal movements (flexion-extension of the elbow) to accomodate experimentally induced changes in the movement time (MT) with constant movement amplitude were examined in man. MT was altered between conditions via instructions and feedback, resulting in seven distinct MT levels (from 100 to 250 ms to the reversal point) with essentially constant movement amplitude. As MT was decreased, the large increases in acceleration were met by two changes in motor control: (a) two-to three-fold increases in the peak accelerations and peak amplitudes of the agonist and antagonist EMGs, and (b) a systematic “compression” of the temporal structure of the entire acceleration-time and EMG-time patterns. This temporal “compression” with increased velocity caused by shifts in MT (distance constant) are considerably different from the constant-duration EMG bursts found when velocity is altered by changing movement distance (where MT is nearly constant). Our findings indicate that MT is a determiner of the temporal structure of rapid actions, and suggest that MT should be regarded as an important controlled variable, and not simply as an emergent property of variations in velocity.

    Notes: Abstract The design and construction of a complex snow fence system, the development and implementation of a visual range monitoring system, and the development and use of a snow profile prediction model for highway design, are used as examples of successful technology transfer. Contributing factors include a strong imperative and commitment to solving an urgent problem; the availability of knowledge, the direct involvement of scientists and engineers working together throughout the planning, implementation, and evaluation stages; and a synergetic relationship between research and application.

    Transport rate of drifting snow and the mean wind speed profile (1986)

    Notes: Abstract Transport rates, measured by weighing snow blown into a filter fabric trap, were greater over hard snow or ice than for the same wind speed over soft, fresh snow surfaces. Analysis of wind speed profiles from nine blizzards showed that friction between moving particles and the surface was less, and particle speeds were greater over hard surfaces. Transport rates at a given wind speed increased rapidly as aerodynamic roughness decreased in the rough-smooth transition region. Bagnold's theory for bed load transport provided a useful framework for the analysis.

    Notes: Abstract Separation of electrostatic charge during the transport of particles by wind adds a force to the gravitational and fluid forces that determine trajectories of particles moving by saltation. Evaluating this electrostatic force requires the electric field strength very near the saltation surface, and charge-to-mass ratios for the moving particles. Field mill readings 4 cm above the surface in a moderate blizzard showed electric field strength as high as +30 kV m-1. Another experiment gave charge-to-mass ratios of individual saltation particles in low-level drifting that ranged between +72 μC kg-1 and -208 μC kg-1. From these measurements, we estimated electrostatic forces as large as the gravitational force on some saltating particles. Including forces of this magnitude in the equations of motion significantly alters predicted saltation trajectories from those for uncharged particles. Predictions appear reasonable that for some saltating particles, the electrostatic force prevents new surface impacts. These results should help improve models of energy transfer in the planetary boundary layer during blizzards and sandstorms.
