The aim of this work was to investigate whether acamprosate modifies the expression of the enzyme responsible for neuronal NO synthesis (nNOS) in the nucleus accumbens (NAc) of mice chronically treated with morphine and during the abstinence syndrome induced by naloxone. The enzyme was monitored by the NADPH diaphorase method. The number of cells stained for NADPH diaphorase in the NAc of mice was counted in 40 μm thick coronal brain slices at 40X. The intensity of the histochemical reaction of stained cells from naive morphine plus saline and morphine plus acamprosate treated mice was analyzed by Image Pro Plus 4.5.1. Morphine administered in a slow release preparation increased the stain intensity of the positive neurons. The increase in the NADPH staining persisted after naloxone was given to mice chronically treated with morphine. Acamprosate antagonized the effects induced by chronic morphine treatment in the NAc of mice. These results indicate that up-regulation of nNOS in the NAc is a consequence of the sustained effects of morphine stimulation, which, in turn, may result from an increased in glutamate release during the abstinence syndrome.

Quantifying the Accuracy of LiDAR-Derived DEM in Deciduous Eastern Forests of the Cumberland Plateau

引用

Journal of Geographic Information System 2017年第3期9卷 339-353页

作者： marco A. contreras Wesley Staats Jian Yiang David Parrott Associate Professor of Forest Management Department of Forestry College of Agriculture Food and Environment University of Kentucky Lexington Kentucky USA Research Assistant Department of Forestry College of Agriculture Food and Environment University of Kentucky Lexington Kentucky USA Assistant Professor of Landscape Ecology Department of Forestry College of Agriculture Food and Environment University of Kentucky Lexington Kentucky USA

Digital elevation models (DEMs) derived from light detection and ranging (LiDAR) technology are becoming the standard in representing terrain surfaces. They have numerous applications in forestry, agriculture, and natural resources. Although elevation errors are much lower than those derived from traditional methods, accuracies have been reported to decrease with terrain slope and vegetation cover. In this study, we quantified the accuracy of airborne LiDAR-derived DEM in deciduous eastern forests of the Cumberland Plateau. We measured relative elevation changes within field plots located across different slope and ruggedness classes to quantify DEM accuracy. We compared elevation change errors of DEMs derived from three LiDAR datasets: a low-density (~1.5 pts•m−2), a high-density (~40 pts•m−2), and a combined dataset. We also compared DEMs obtained by interpolating the ground points using four interpolation methods. Results indicate that mean elevation change error (MECE) increased with terrain slope and ruggedness with an average of 73.6 cm. MECE values ranged from 23.2 cm in areas with lowest slope (0% - 39%) and ruggedness (0% - 28%) classes to 145.5 cm in areas with highest slope (50% - 103%) and ruggedness (46% - 103%) classes. We found no significant differences among interpolation methods or LiDAR datasets;the latter of which indicates that similar accuracy levels can be achieved with the low-density datasets.

Aphids （Hemiptera： Aphididae） are phytophagous insects that are important agricultural pests. The enormous negative economic impacts caused by aphids worldwide are well known, and are mostly due to their high multiplication rate and the transmission of phytopathogenic viruses. Aphid management strategies mainly involve chemical treatments which are pollutants and are increasingly inefficient, since aphids have developed multiple insecticide-resistant mechanisms. Among the most economically important species is the green peach aptfid Myzus persicae Sulzer （Aphididae： Macrosiphini）, which is able to colonize a wide range of host plants belonging to many different families, and transmits numerous plant viruses. Because of its large prevalence, M. persicae has been the target of massive insecticide treatments; consequently, it has evolved several insecticide-resistant mechanisms. In this work, a collection of expressed genes from M. persicae is presented in order to identify putative genes involved in xenobiotic detoxification. After cDNA cloning and sequencing, 959 expressed sequence tags （EST） were annotated. Most sequences matched known genes corresponded to metabolism proteins （26%）, ribosomal proteins （ 23 % ） and structural proteins （8%）. Among them, several sequences corresponded to proteins putatively involved in sensing, degradation or detoxification of plant xenobiotic products.

Non-Topological Solitons as Traveling Pulses along the Nerve

International Journal of Modern Nonlinear Theory and Application 2013年第4期2卷 195-200页

作者： Fidel contreras Fernando Ongay Omar Pavón Máximo Aguero Instituto Literario Facultad de Ciencias Universidad Autonoma del Estado de Mexico Toluca México

Several new soliton-like structures have been obtained under the consideration of non trivial boundary condition for the difference value of density in the thermodynamic model of nerve pulses. The model is based on thermodynamic principles of zero transfer of energy to the media. We have studied these solutions for particular values in the parameter space, and obtained both bell soliton on the condensate and bubble like solutions as typical non-topological representative solutions. The solutions will propagate along the nerve with constant velocity. The analysis of the properties of the solutions provides us with available permitted velocities and the prediction of the constant density value of the background at long distances far from the excited zone in the nerve.

The improved Boussinesq equation is solved with classical finite element method using the most basic Lagrange element k = 1, which leads us to a second order nonlinear ordinary differential equations system in time;this can be solved by any standard accurate numerical method for example Runge-Kutta-Fehlberg. The technique is validated with a typical example and a fourth order convergence in space is confirmed;the 1- and 2-soliton solutions are used to simulate wave travel, wave splitting and interaction;solution blow up is described graphically. The computer symbolic system MathLab is quite used for numerical simulation in this paper;the known results in the bibliography are confirmed.
