The effect of post-irradiation shelf-aging time on the wear of orthopaedic grade UHMWPE was investigated, and wear results were correlated with the time-dependent microstructural changes of polyethylene after gamma irradiation sterilization. The levels of oxidation, crosslinking, and crystallinity in the shelf-aged acetabular liners were examined by FTIR, hot xylene extraction, and DSC, respectively. Uni-directional repeat pass sliding wear tests were conducted by using a pin-on-disc wear tester. ...

Although there have been studies that focused on the correlation between the HPV presence of pelvic lymph nodes and pathological metastasis in patients with cervical cancer, the biologic role of HPV DNA in lymph nodes still remains uncertain. We performed this study to investigate the correlation between the sentinel-node HPV status and pelvic lymph node metastasis in patients with cervical cancer. The patients were followed up for 3 years to evaluate the clinical role of HPV in sentinel nodes as ...

The tripartite motif containing (TRIM) proteins are a large family of proteins that have been implicated in many biological processes including cell differentiation, apoptosis, transcriptional regulation, and signaling pathways. Here, we show that TRIM15 co-localized to focal adhesions through homo-dimerization and significantly suppressed cell migration. Domain mapping analysis indicated that B-box2 and PRY domains were essential for TRIM15 localization to focal adhesions and inhibition of cell ...

Background: Laparoscopic appendectomy is generally performed with the three-port system. In this study, we performed a unique single-port laparoscopic appendectomy, which we refer to as the transumbilical single-port laparoscopic appendectomy (TUSPLA). Methods: From April 19, 2008, 33 cases of TUSPLA were performed. A surgical glove was used as the “single-port” with an extra-small wound retractor, which was set up through a small umbilical incision. The surgical glove attached with one trocar and ...

Objective Autophagy plays a vital role in homeostasis by combining organelles and cellular proteins with lysosome under starvation conditions. In addition, autophagy provides tumor cells with a source of energy. Continued autophagy will induce cells death. Here we aim to see if autophagic induction has an effect on conventional chemotherapeutic agents. Methods Rapamycin, or mammalian target of rapamycin and paclitaxel, apoptosis-inducing agents were used autophagy in HeLa cervical cancer cells. ...

We examine the band structure and the dielectric response of confined Si systems such as quantum wells and wires through first-principles pseudopotential calculations and find the direct band gaps. With the surfaces of the quantum systems saturated by hydrogen atoms, the optical excitation peaks in the range of visible light are prominent, as compared to those with unsaturated Si dangling bonds. In quantum wires, we find luminescence excitation peaks near the band-gap energy, in good agreement with ...

A multilayer of TiN–TiC has been deposited on commonly used die steels (D2) by the pulsed DC plasma-assisted chemical vapor deposition process. The TiC layer was successfully deposited at 580°C with a gas mixture of TiCl4, CH4, H2 and Ar. A minimum flow of TiCl4 (3.5 g/h) and CH4 gas (18–20 sccm) were used to minimize the excess carbon phases and the chlorine content in the TiC deposited layer. A gas volume ratio of TiCl4/CH4 in the range 0.34–0.38 is required to obtain dense TiC films with minimum ...

Many studies regarding spinal sagittal alignment were focused mainly on above-hip structures, not considering the knee joint. Knee-spine syndrome was proposed earlier, but the mechanism of this phenomenon has not been revealed. The aim of the study was to demonstrate how spinopelvic alignment and sagittal balance change in response to simulated knee flexion in normal non-diseased population.Thirty young male were enrolled in the study cohort.
