Fast ions in fusion plasmas often leave characteristic signatures the plasma neutron emission. Measurements of this emission are subject to phase-space sensitivity diagnostic, which can be mapped using weight functions. In paper, we present orbit functions for TOFOR and NE213 diagnostics at Joint European Torus, mapping their 3D space. Both highly sensitive fast that spend a relatively large fr...
Gastric cancer (GC) remains the second leading cause of cancer-related death worldwide. Owing to the lack of early diagnostic techniques, GC is often diagnosed at advanced stage and that leading to low survival rate. Growing evidences have been suggesting that circulating microRNAs play an important role in earlier diagnostic of disease. In the present study, we analyze the circulating miRNAs e...
Objective Long noncoding RNAs (lncRNAs) have been reported to play vital roles in non-small-cell lung cancer (NSCLC). Recently, long noncoding RNA Linc00152 has been reported to play important roles in various cancers. In this study, our aim was to investigate its expression pattern and clinical significance and further evaluate its diagnostic value for NSCLC. Methods The levels of Linc00152 ...
A plasma diagnostic technique for measuring the electron density, electron temperature, and ion current near a surface in radio frequency ~rf! discharges is proposed. The sensor uses a small wire probe to determine the plasma potential and a small metal electrode to measure the current and voltage profiles. The values of current, sheath voltage, and time derivative of sheath voltage at three di...
Amyloid-β (Aβ) plays a critical role as a biomarker in Alzheimer's disease (AD) diagnosis. In addition to its diagnostic potential in the brain, recent studies have suggested that changes of Aβ level in the plasma can possibly indicate AD onset. In this study, we found that plasma Aβ(1-42) concentration increases with age, while the concentration of Aβ(1-42) in the cerebrospinal fluid (CSF) dec...
Development of negative hydrogen ion sources for neutral beam systems is closely linked with an optimisation of negative ion formation in hydrogen plasmas which requires knowledge of the plasma parameters. Emission spectroscopy is introduced as a non-invasive and in-situ diagnostic tool for line of sight averaged plasma parameters. Diagnostic lines and simplified analysis methods for a variety ...
