Extracorporeal membrane oxygenation (ECMO) can support neonates with severe respiratory failure. Currently, the most common application of ECMO requires venoarterial access. Venovenous (VV) ECMO is desirable to avoid common carotid artery ligation. However, the best technique of venous access for VV ECMO is not established. Using a single cannula with a double-lumen (DLC) in the right atrium fo...

Diamond Like Carbon (DLC) films were deposited on quartz substrates using Dense Plasma Focus (DPF) method. The formation of sp bonds as is it’s content in the film strongly depends on the substrate and it seems quartz is not a suitable substrate. However, we report here the formation of DLC films on quartz substrates that were maintained at elevated temperatures and show the content of carbon a...

Abstract The goal of this work is to evaluate the potential diamond-like carbon (DLC) coatings on thermoplastic polymers for friction and wear reduction in highly stressed rolling–sliding contacts. Therefore, hydrogen-containing DLC were deposited polymer surface by a low-temperature high power pulsed magnetron sputtering (HPPMS) physical vapor deposition (PVD) process. rolling-sliding contact ...

DLC-1 (deleted in liver cancer-1) is a tumor suppressor gene for hepatocellular carcinoma and other cancers. To characterize its functions, we constructed recombinant adenovirus encoding the wild-type DLC-1 and examined its effects on behaviors of a hepatocellular carcinoma cell line (SNU-368), which does not express DLC-1. Here, we found that restoration of DLC-1 expression in the SNU-368 cell...

Owing to its superior tribological and mechanical properties with corrosion resistance, biocompatibility, and hemocompatibility, diamond-like carbon (DLC) has emerged as a promising material for biomedical applications. DLC films with various atomic bond structures and compositions are finding places in orthopedic, cardiovascular, and dental applications. Cells grew on to DLC coating without an...

The tensin family member cten (C-terminal tensin like) is an Src homology 2 (SH2) and phosphotyrosine binding domain-containing focal adhesion molecule that may function as a tumor suppressor. However, the mechanism has not been well established. We report that cten binds to another tumor suppressor, deleted in liver cancer 1 (DLC-1), and the SH2 domain of cten is responsible for the interactio...

In our previous study we demonstrated the downregulation or loss of deleted in liver cancer‑1 (DLC-1) gene expression in nasopharyngeal carcinoma (NPC). In this study, we report the effects of the DLC-1 gene on NPC cells and its mechanisms of action. DLC-1 expression was restored in the 5-8F NPC cell line, which lacks DLC-1 expression, and the biological characteristics of 5-8F-DLC‑1 cells were...

Biomedical applications of diamond-like carbon (DLC) coatings are continuously increasing due to their superior mechanical properties, low friction coefficient, antiwear characteristics, and biocompatibility. The tribological characteristics DLC have been comprehensively investigated on various substrate systems as a function deposition parameter dependant features for biomaterial applications....

Diamond like carbon (DLC) films were deposited on Si and then patterned to form 40 nm features as nanoimprint templates. A plasma enhanced chemical vapor deposition (PECVD) system with CH4 precursor was used to deposit DLC films on Si and quartz substrates. These films were then characterized using Raman spectroscopy, atomic force microscopy (AFM), nanoindentation, and contact angle measurement...
