Recent studies reported the translocator protein (TSPO) to play critical roles in several kinds of neurological diseases including the inflammatory and neuropathic pain. However, the precise mechanism remains unclear. This study was undertaken to explore the distribution and possible mechanism of spinal TSPO against chronic neuropathic pain (CNP) in a rat(More)
Although progesterone was reported to be a neuroprotective agent against injuries to the nervous system, including the peripheral neuropathy, the mechanisms of its dose or timing-related effects remain unclear. Translocator protein (TSPO) is predominantly located in the mitochondrial outer membrane and has been recently implicated in modulation of several(More)
BACKGROUND We assessed the effects of smoking and smoking cessation on life expectancy and active life expectancy among persons aged 55 years or older in Beijing. METHODS This study included 1593 men and 1664 women who participated in the Beijing Longitudinal Study of Aging, which commenced in 1992 and had 4 survey waves up to year 2000. An abridged life(More)
This paper proposes an improved chaos-based color pathological image encryption algorithm, using SHA-2 to generate one-time keys. In order to send different ciphered images to different recipients, the hash value of the plain image and a random number are applied to generate one-time initial conditions for Chebyshev maps, to make the key stream change in(More)
The paper proposes an improved reversible substitution method to hide data into deoxyribonucleic acid (DNA) sequence, and four measures have been taken to enhance the robustness and enlarge the hiding capacity, such as encode the secret message by DNA coding, encrypt it by pseudo-random sequence, generate the relative hiding locations by piecewise linear(More)
Snake-like robots exhibited more advantages than conventional mobile robots on environment adaptation. They almost can move in most ill conditions including rough terrain, desert, water, cave and tree. In this paper, a 3D snake-like robot called Perambulator-II (Shenyang Institute of Automation snake-like robot II) is developed with the acquirement of(More)
