Parkinson's disease (PD) is an age-related neurodegenerative movement disorder, characterized by loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The MPTP/MPP+ model is often used to investigate the signaling mechanisms of dopamine (DA) degeneration, both in vivo and in vitro. The identification of specific genetic and(More)

Encryption algorithm based on higher degree residues is presented in this paper, including both deterministic and probabilistic. Since the algorithms have homomorphic properties, i.e., the ability to perform algebraic operations such as additions or subtractions directly on ciphertext, they can be applied in several specific fields. Except for ensuring(More)
OBJECTIVES To analyze intraepidermal nerve fiber density (IEFND) by skin biopsy, evaluate the effect of age, anatomical sites, and ethnic origin on IEFND and develop a reference range of IENFD at the distal leg of healthy human. METHODS Seventy skin biopsy specimens from surgical procedures involving 70 patients were analyzed. Specimens were fixed(More)
An algorithm of online similarity query of dynamic time sequences is proposed as for the need of time sequences real-time analysis. This algorithm uses improved Euclidean Distance as similar measurement and then evaluates the similar distance between dynamic time sequences and pattern time sequences in a batch pattern using Fast Fourier Transform. In order(More)
The study was aimed to observe the morphology of intraepidermal nerve fibre (IENF) and to explore the relationships between intraepidermal nerve fibre density (IENFD) and anatomic sites, age, genders and races. Intraepidermal nerve fibre was observed using immunohistochemistry. The relationships between IENFD and anatomic sites, ages, genders and races were(More)
