The purpose of this study was to investigate the distribution of CD34-positive fibroblasts and alpha-smooth muscle actin (alpha-SMA)-reactive myofibroblasts in the stroma of benign and malignant breast lesions and, secondly, to determine whether the presence of stromal myofibroblasts is associated with some of the clinicopathological characteristics of(More)
Fertility and early embryonic developmental toxicity in rats were evaluated by intravenously administering astragaloside IV (AS-IV) daily at 0.25, 0.5, and 1.0 mg/kg for 4 weeks before mating, throughout the mating period, and continuing to day 6 of gestation period in females. Perinatal toxicity in rats was evaluated on gestational days (GD) 15 to 21 and(More)
In power system, pulse voltage is measured by both the circuit and the electric field. The special measure of VFTO is determined by non-alterable equipments of GIS. In this paper, external transient voltage is measured by electric spherical probe which means it is not necessary to access any equipment to the system. According to actual space between three(More)
Based on the body's characteristic of large product of inertia, the nonlinear dynamic turning-model of the high-temperature ladle carrier vehicle is established by Newton-Euler method. The simulation for a certain type of high-temperature ladle carrier vehicle is made to show that the increment of the roll angle's amplitude, which is affected by the large(More)
