Particle deposition/erosion can affect mirrors used in plasma diagnostics and this is a major concern for future fusion reactors. This subject is analyzed for the first and second mirrors of the proposed Motional Stark Effect edge plasma current diagnostic for ITER. Particle fluxes to the diagnostic module aperture are given by edge-plasma/impurity-transport solutions for convective plasma flow...
Plasma focus (PF) device belongs to the family of dynamic non-cylindrical Z-pinches. In this device hot dense magnetized plasma is created as a result of a discharge between coaxial electrodes over a surface of isolator in a working gas. If the working gas is deuterium, then DD fusion reactions take place, in the so-called plasma column or plasma pinch, which is created at the end of a central ...
Fetal DNA is present in the plasma of pregnant women. Massively parallel sequencing of maternal plasma DNA has been used to detect fetal trisomies 21, 18, 13 and selected sex chromosomal aneuploidies noninvasively. Case reports describing the detection of fetal microdeletions from maternal plasma using massively parallel sequencing have been reported. However, these previous reports were either...
BACKGROUND Molecular analysis of plasma DNA during human pregnancy has led to the discovery that maternal plasma contains both fetal and maternal DNA. This valuable source of fetal DNA opens up new possibilities for noninvasive prenatal diagnosis. APPROACH Published data from the last 3 years demonstrating the feasibility and utility of analyzing fetal DNA in maternal plasma are reviewed. C...
Dust particles can be a useful plasma diagnostic tool. Sufficiently dust particles can be used as test grains for the visualization of the plasma potential distribution; larger dust particles can be used as specific probes to determine electron temperature. Here we report on diagnostic measurements carried out in a capacitively coupled planar rf discharge. The location of the sheath edge has be...
Waldenström's macroglobulinemia is a B-cell neoplasm characterized by infiltration of the bone marrow by a lymphoplasmacytic infiltrate and an IgM monoclonal gammopathy. It is an uncommon disease with overall incidence of approximately 3 per million persons per year, accounting for approximately 1% to 2% of all hematologic cancers. It has only one-sixth the estimated prevalence of plasma cell m...
Several risk factors for type 2 diabetes mellitus (T2DM) are also associated with blood concentrations of persistent organic pollutants (POPs), and related to the disease may affect POP concentrations, subsequent associations between POPs T2DM. The purpose this pilot study was investigate change in lipids, hormones pre- post-diagnosis T2DM cases compared healthy controls their We measured POPs,...
The study of plasma accelerated ions is an important topic nowadays [1]. The acceleration of ions is produced for electric fields caused by plasma density gradients. So a diagnostic of the plasma density and temperature is necessary. It is frequently achieved using spectroscopic methods with the light from He-like and Li-like plasma ion transitions emitted in the soft x-ray region, 1-1000 Å wav...
BACKGROUND Diagnosis of pheochromocytoma (PC) is based on a combination of clinical suspicion, finding an adrenal mass, increased plasma, and urine concentrations of catecholamine metabolites and is finally confirmed with histopathology. In human medicine, it is controversial whether biochemically testing plasma is superior to testing urine. OBJECTIVES To measure urinary and plasma catecholam...
MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional gene expression regulators. The expression profiling of miRNAs has already entered into cancer clinics as diagnostic and prognostic biomarkers to assess tumor initiation, progression and response to treatment in cancer patients. Recent Studies opened the way for the use of circulating miRNAs as non-invasive diagn...
