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)
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)
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)
Laparoendoscopic single-site surgery and natural orifice transluminal endoscopic surgery attempt to reduce transabdominal port sites. These require all instruments to pass through a single access point, leading to instruments collide or work at unfamiliar angles. Thus, we designed an internal grasper under magnetic anchoring guide system (MAGS) platform and(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.
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)
