The aim of the present study was to determine the effects of metformin, combined with a p38 mitogen‑activated protein kinase (MAPK) inhibitor, on the sensitivity of cisplatin‑resistant ovarian cancer to cisplatin. The expression and distribution of phosphorylated p38 MAPK (P‑p38 MAPK) was confirmed in drug‑resistant and primary ovarian cancer tissues by… (More)
SiGe heterojunction bipolar transistor (HBT) technology has been widely applicated in microwave communication system since 1987 as first SiGe HBT was invented. In this paper, its development is reviewed and its propertis, structures, manufacturing process, and application are introduced.
OBJECTIVE To study the curative effect and prognosis of patients with basal ganglia cerebral hemorrhages treated using a transcortical-sulcus approach and compare with results obtained using the traditional cerebral cortex approach. METHODS Clinical data were collected from 106 patients with hypertensive hemorrhage in the basal ganglia who were treated… (More)
BACKGROUND The aim of this study was to explore the mechanism by which cervical cancer is inhibited by promoting IGFBP7 expression using ellagic acid from pomegranate peel extract. MATERIAL AND METHODS HeLa cells were divided into 6 groups: control group (NC), blank control group (BL), and IGFBP7 overexpression group (IGFBP7), and 2.5 uM, 5. 0 uM, and 10.0… (More)
Compared with UV embossing and micro-contact imprinting, hot embossing technology is the first to be used in nano-imprint lithography, and is access to copying the parallel structure in micro-nano-scale at low cost and relatively faster speed. This paper explores which factors influence some pattern transferring accuracy appearing in the experiment: the… (More)
A multi-factor model for the grain yield prediction based on the previous data and relevant impacting factors is reported. In this model, the weight coefficient of each individual factor that affected the grain yield historically is analyzed by the variation coefficient method and the conversion degree function in the attribute theory. The effects of… (More)
