In order to evaluate mechanisms of natural plant purslane herb aquenous extracts (PHAS) for neuroprotective, we assessed neuroprotective effects of PHAS at doses of 2.5, 5 and 10 mg/(kg day) on SD mice injected daily with D-gal (50 mg/(kg day)) by behavioral tests. PHAS-fed mice showed higher activity upon induction by new environmental stimuli, lower(More)
E-mail's text is the main body of an E-mail. Its content is reflected by semantic body formed by a large number of semantic elements, so it is the most authoritative and effective to study semantic body information of spam when analyzing its text. Firstly, this paper takes the advantage of HowNet in analysis of semantic element and analyze semantic bodies(More)
Percutaneous vertebroplasty (PV) and kyphoplasty (PK) are the 2vertebral augmentation procedures that have emerged as minimally invasive surgical options to treat painful vertebral compression fractures (VCF) during the last 2 decades. VCF may either be osteoporotic or tumor-associated. Two hundred million women are affected by osteoporosis globally.(More)
BACKGROUND The aim of this study was to evaluate the feasibility of treating vertebral compression fractures using an autonomously developed nitinol memory alloy vertebral stent. MATERIAL AND METHODS Thoracolumbar vertebral specimens from adult human cadavers were made into models of compression fractures. The models were divided into group A, which(More)
Human colon cancer is the leading cause of cancer death in both men and women worldwide. The c-Myc gene is frequently deregulated and overexpressed in this malignancy, and strategies designed to inhibit c-Myc expression in cancer cells may have considerable therapeutic value. We design and use short hairpin RNA (shRNA) to inhibit c-Myc expression in Colo(More)
Pantothenate (vitamin B(5)) is the precursor of the 4'-phosphopantetheine moiety of coenzyme A and acyl-carrier protein. It is made by plants and microorganisms de novo, but is a dietary requirement for animals. The pantothenate biosynthetic pathway is well-established in bacteria, comprising four enzymic reactions catalysed by ketopantoate(More)
This paper introduces a technical scheme of auxiliary power supply system of passenger train based on photovoltaic and energy storage, renewable energy will be injected into the power supply system of train by this system. This paper introduces the technical characteristics, energy consumption level and application situation of Chinese passenger trains,(More)
Lebus groove can realize multilayer and orderly winding of wire, so it is widely used in hoisting equipment. But these types of grooves are difficult to manufacture in average lathe. Coping with this situation, the paper developed the Lebus groove CNC system based on PMAC. The hardware components, system functions, software programming and other key(More)
