Circulating tumor DNA (ctDNA), which includes DNA mutations, epigenetic alterations and other forms of tumor-specific abnormalities, is a promising "real-time" biomarker for noninvasive cancer assessment. Tumor DNA is of great value in the process of cancer treatment, including diagnostic and prognostic information before, during treatment and at progression. Here we introduce a peptide nucleic...

To compare a conventional cathode-ray tube (CRT) screen to organic light-emitting diode (OLED) and liquid crystal display (LCD) screens as visual stimulators to elicit multifocal electroretinograms (mfERGs), mfERGs were recorded from seven eyes of seven healthy volunteers (21 ± 2 years). The mfERGs elicited by a conventional CRT screen (S710, Compaq Computer Co.) were compared to those elicited...

Background: In the patients with acute exacerbated chronic obstructive pulmonary disease (AECOPD), gut displays ischemia, anoxia and oxidative stress, which lead to intestinal barrier failure. Therefore, it is desirable screen for effective barrier-related biomarkers monitor severity.

Abstract. There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures coefficient at 532 1064 nm. Here we describe its design, calibration mode operation evaluate applicability, limits uncertainties. The nm channel was calibrated ∼ 1 µmol mol...

Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in both traumatic brain injury (TBI) survivors and elderly subjects. Similarly, computer-based biofeedback (BF) training has resulted in decreased sway during quiet stance and decreased reaction times during a dual-task reaction time paradigm in elderly subjects. The objective of this study ...

The emergence of the SARS-CoV-2 virus and associated pandemic has affected entire human population. Human susceptibility to highlighted a tremendous need for affordable diagnostic systems manage monitor effectiveness vaccination. We have developed simple label-free electrochemical immunosensor detection anti-SARS-CoV-2 IgG antibodies, which consists supporting screen-printed carbon electrode (S...

The application of genetically encoded biosensors enables the detection small molecules in living cells and has facilitated characterization enzymes, their directed evolution engineering (natural) metabolic pathways. In this work, LuxAB biosensor system from Photorhabdus luminescens was implemented Escherichia coli to monitor enzymatic production aldehydes primary alcohols carboxylic acid subst...

This paper proposes a simple method for realizing a multi-screen immersive display using one PC with dual graphic cards and workflow on which CG creators can create animation movie. This method realizes a multi-screen immersive display without any special hard ware and engineering technology. We implement the non-interactive, non-stereo projection system which projects the integrated movie cons...

aim: this study aimed to assess the relationship of screen time and metabolic syndrome (mets) among iranian adolescents. materials and methods  in this nationwide study, the propensity score (ps) was used in a matched case-control study design. the data was obtained from 5,625 students aged 10-18 years, who participated in a national school-based surveillance program. mets was defined according...
