The iron chelator deferoxamine (DFX) is efficacious in ameliorating hypoxic-ischemic brain injury. However, the effect of DFX worked in the ischemic and the mechanism is still unclear. Recent studies have shown that apoptosis and oncosis may be the pathways of cell death accountable for astrocytic death in the ischemic core. The effect of DFX on primary(More)
Cerebral ischemia was induced using photothrombosis 1 hour after intraperitoneal injection of the p38 mitogen-activated protein kinase (MAPK) inhibitor SB239063 into Swedish mutant amyloid precursor protein (APP/SWE) transgenic and non-transgenic mice. The number of surviving neurons in the penumbra was quantified using Nissl staining, and the activity of(More)
Although image contrast enhancement is a low level image processing issue, it is very important for improving image quality. This paper propose a new algorithm using optimal linear transform to enhance color image while preserving hue attributes and scaling saturation for each color pixel. The algorithm has two features: 1) optimal piecewise affine(More)
A new non-photorealistic rendering algorithm is proposed for creating artistic painting with soft stream flow from natural color images. The algorithm consists mainly of two stages, that is, a revised bilateral filter called trilateral filter is firstly applied to original color image for creating drawings using gradient information and then a DoG-like(More)
Based on the general syllable structure, a syllable’s component letters should be expanded orderly into the series of basic consonant, prefix consonant, head consonant… and the second suffix consonant. If there is no letter in a syllable’s particular position, a special character, whose collation element is less than that of any(More)
In this paper, the two invariants in the perspective projection model of camera imaging process are analyzed and a five-point constraint is put forward. And then methods of determining the true projective position of the circular target using a concentric circular target, and an optimal method of suppressing stochastic errors in the location of circle(More)
