among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

Import of tRNA into the mitochondrial matrix of Trypanosoma brucei was reconstituted in vitro. Efficient import required the hydrolysis of externally added ATP and was shown to be a carrier-mediated process depending on proteinaceous receptors on the surface of mitochondria. A partly synthetic tRNA(Tyr) as well as a physiological tRNA(Lys) were imported along the same pathway. Contrary to impor...

Mitochondrial biogenesis is accompanied by an increased expression of components of the protein import machinery, as well as increased import of proteins destined for the matrix. We evaluated the role of the outer membrane receptor Tom20 by varying its expression and measuring changes in the import of malate dehydrogenase (MDH) in differentiating C2C12 muscle cells. Cells transfected with Tom20...

The import of proteins into peroxisomes possesses many unusual features such as the ability to import folded proteins, and a surprising diversity of targeting signals with differing affinities that can be recognized by the same receptor. As understanding of the structure and function of many components of the protein import machinery has grown, an increasingly complex network of factors affecti...

Leucoplasts are important organelles for the synthesis and storage of starch, lipids and proteins. However, molecular mechanism of protein import into leucoplasts and how it differs from that of import into chloroplasts remain unknown. We used pea seedlings for both chloroplast and leucoplast isolations to compare within the same species. We further optimized the isolation and import conditions...

The human population is rising and will soon reach 9 billion people. In parallel, the demand for animal protein is increasing and with it is the threat of zoonotic diseases. We must therefore be on our guard. The close association of people with animals promotes the opportunity for zoonotic infections and real danger may arise when animals are imported with no health background. Therefore, it i...

* 0-7803-7952-7/03/$17.00 © 2003 IEEE. Abstract This paper presents the Disciple-RKF methodology for rapid development of large knowledge bases which relies on importing ontological knowledge from existing knowledge repositories, on parallel development of separate knowledge bases by subject matter experts, and on the merging of these knowledge bases into a high performance integrated knowledge...

The paper introduces a new approach based on dual residue system to compute Montgomery multiplication. The novelty of this proposal is that we import an extra Montgomery residue system with new transformation constant beside the normal one. In this way, one of the multiplicand can be divided into two parts and both higher and lower parts are calculated in parallel to speed up computation. Then ...

In this article a numerical MATLAB algorithm is presented to visualize the workspace of serial and parallel kinematics. For serial kinematics the Monte Carlo Method is used to convert the inputted DH-Parameters to a scatter plot of the reachable workspace. The article gives also a detailed insight into the processing of these scatter plot to find and visualize the boundary points of the workspa...
