PURPOSE To investigate whether topical application of Baicalin affords protecting Balb/C mice epidermis from ultraviolet (UV)B-induced DNA damage and its underlying mechanisms. METHODS A DNA damage model of UVB irradiation-induced mice epidermis was established. The immunohistochemical staining, Southwestern dot-blotting were used for cyclobutane(More)
It has proposed an adaptive threshold edge detection algorithm in this paper, which applies the bilateral filtering that has the advantages of edge-preserving and noise-removing firstly. Then it uses OTSU, which is based on gradient magnitude to maximize the separability of the resultant classes, to determine the low and high thresholds of the canny(More)

Assigning and scheduling vehicle routes in stochastic traffic network is a crucial management problem. Vehicle routing problem (VRP) is a combinational optimization problem, it belongs to the NP-hard problem theoretically. VRP with time windows and capacity constraint in stochastic traffic network was studied considering the state of traffic network(More)
Mine multimedia rescue communication has the paroxysmal of time, uncertainty of place, complicacy of condition and multiformity of information, which has more strict requirements. Mine multimedia rescue communication system adopts an integration of MPEG4, VOIP, TCP/IP and self-organizing technology etc. It is carried by the rescue workers, and the system(More)

Customer Relationship Management (CRM) is adapted “product-centric” to “customer-centric” business model. The relationship marketing strategy needs developed a new management philosophy. Customer segmentation and customer value is the one of the core functions of CRM, customer's access, customer retention and customer value-added(More)
Epstein-Barr virus (EBV) replication and transcription activator (Rta) is an immediate-early transcription factor that mediates the switch from latent to lytic infection. DNA viruses often modulate the function of critical cell cycle proteins to maximize the efficiency of virus replication. Here we have examined the effect of Rta on cell cycle progression.(More)
We describe a 24-year-old man with type 1 diabetes mellitus and a cavitary lesion in the right upper lobe, caused by a zygomycete. Surgical resection plus liposomal amphotericin B therapy was successful. We discuss predisposing condition, clinical findings, diagnosis, and treatment of pulmonary zygomycosis.
The credit crisis has become increasingly apparent and it has become the biggest bottleneck of the development of China's e-commerce. The main factors that influence China's e-commerce credit are social credit consciousness, virtual network environment, legal environment, credit mechanism, management mechanism and so on. The construction of e-commerce(More)
In this paper, a variable-step ANF for estimation of power quality frequency is presented. This algorithm is fast and accurate. It still get a satisfied result under a high sampling rate. The algorithm of adaptive IIR notch filter with variable-step is presented in detail, and some variable-step method is presented. At last, the simulation is performed by(More)
OBJECTIVE This study investigated the reconstructed mandibular condylar cartilage and the ultrastructural variations in mandibular condylar cartilage in adult rats as a result of mandibular advancement. METHODS Thirty 9-week-old male Sprague-Dawley rats were randomly divided into experimental and control groups. Rats in the experimental group were(More)
