BACKGROUND The implication of nitric oxide (NO) in the development of human African trypanosomiasis (HAT) using an animal model, was examined. The manner by which the trypanocidal activity of NO is impaired in the periphery and in the brain of rats infected with Trypanosoma brucei brucei (T. b. brucei) was analyzed through: (i) the changes occurring in NO concentration in both peripheral (blood...

Abstract Aquifer hydraulic parameter can change during earthquakes. Continuous monitoring of the response water level to seismic waves or solid Earth tides provides an opportunity document how earthquakes influence hydrological properties. Here, we use data two groundwater wells, Dian-22 (D22) and Lijiang (LJ) well, in southeast Tibet Plateau 2015 Mw 7.8 Gorkha earthquake illustrate implication...

The captions for Figure 2C,D have several minor errors numbering of the residues of Aβ. The corrected captions should read: (C) NMR-based structural model of Aβ1−40 fibrils showing central residues K16−D22 and A30−V36. (D) NMR-based structural model of Aβ1−42 fibrils showing central residues L17−I41. These errors are peripheral to this paper and do not affect the results or conclusions in any way.

A series of 56 ssDNA aptamer variants that bind to diclofenac (DCF) were selected from an initial pool of 2.4x10(14) ssDNA molecules by Flu-Mag SELEX process. Sequence analysis of these aptamer variants showed three major groups based on sequence similarity in their random N40 sequences. Out of these, four aptamers designated as D10/DA24, D22, D16, and D3 showed high affinity to DCF with K(d) v...

We present a new approach for the empirical investigation of agglomeration patterns. We examine the clustering of manufacturing firms by identifying patterns of spatial network formation that deviate from randomly generated networks. Using firm-level panel data from Vietnam we calculate transitivity, a measure to determine the strength of clustering of manufacturing firms. We then test whether ...

This paper considers the effect of acquisition FDI on the knowledge production function. We distinguish between acquisitions by MNEs from technologically leading countries and those behind the technological frontier. We show that both acquire similarly R&D intensive domestic firms, but there are important differences post-acquisition. Acquisitions from technologically intensive countries reduce...

abstract efficiency concept has a long history in the sciences and its measurement and analysis is a vital importance for firms to achieve the best performance. hence, the aim of this paper is efficiency evaluation of mahan air compared to iata member airlines in middle east and africa. for this purpose, the indicators include available ton kilometer, revenue ton kilometer, revenue passenger ki...

Product recall data and information on stock price reactions to recalls are used estimate the value of reputation in a model which product quality is not contractible. A result defect that signals low effort. The triggers reduction firm’s value, then both rise steadily until its next occurs. We accounts for 8.3 percent firm welfare 26 first best level. policy intervention attains tax accompanie...
