OBJECTIVE Loss of function mutations of Park7/DJ-1 gene increase the susceptibility of dopaminergic cells to reactive oxygen species and cause early onset familial Parkinson disease (PD). However, the mechanisms underlying dopaminergic neuron loss related to DJ-1 mutation remain undefined. Therefore, it is important to find the new mechanisms underlying the(More)
As the widely application of digital multi-media technology, G.729 has become one of the most popular audio standards. In this paper, the TMS320DM6446 which is a Davinci-based multi-core processor is chosen as our platform. We present our implementation method of G.729 algorithm which is compatible with eXpress DSP algorithm interface standard - digital(More)
Introduction The last decade has witnessed that random exchange models have been developed in the field of econophysics and applied into various economic issues. This kind of models was proposed to explore the underlying mechanism of wealth distribution or income distribution. Besides static distribution, these models have also been used to study the(More)
This study investigates the neuroprotective properties of berberine (a natural isoquinoline alkaloid isolated from the Rhizoma coptidis) and finds that berberine could promote β-amyloid (Aβ) clearance and inhibit Aβ production in the triple-transgenic mouse model of Alzheimer's disease (3×Tg-AD). During the study, berberine was first administrated to treat(More)
We comprehensively illustrate a general process of fitting all-atom molecular mechanics force field (FF) parameters based on quantum mechanical calculations and experimental thermodynamic data. For common organic molecules with free dihedral rotations, this FF format is comprised of the usual bond stretching, angle bending, proper and improper dihedral(More)
H.264 is well known as best video codec ever. And mediastreamer2 is an open-source software to make audio and video real-time streaming and processing. Written in pure C, it is based upon the ortp library. This paper presents the method of how to implement h.264 video streams transfer based on mediastreamer2. In the end we show the actual performance of our(More)
