Surface-enhanced Raman scattering (SERS) presents a promising avenue for trace matter detection by using plasmonic nanostructures. To tackle the challenges of quantitatively analyzing substances in SERS, such as poor enrichment efficiency and signal reproducibility, this study proposes novel approach Au@internal standard@Au nanospheres (Au@IS@Au NSs) realizing high sensitivity stability SERS substrates. verify feasibility performances, substrates have exhibited exceptional detecting methyl...
Evaluating the role of IL-6 and CD4+/CD8+ in predicting prognosis elderly patients with acute exacerbations chronic obstructive pulmonary disease (AECOPD). This study retrospectively enrolled 413 who were hospitalized for AECOPD between January 2019 December 2021. Patients divided into event non-event groups based on whether they readmitted or died due to during 18 months follow-up. The associations adverse events assessed using Cox proportional hazards regression models, Kaplan-Meier...
A vast majority of nonlinear behavior in atmospheric pressure discharges has so far been studied the space domain, and their time-domain characters are often believed to exact periodicity externally applied voltage. In this paper, based on one-dimensional fluid mode, we study complex time domain argon dielectric-barrier at very broad frequency range from kilohertz megahertz. Under certain conditions, discharge not only can be driven chaos time-periodic state through period-doubling...
Eu2+/Tb3+ single-doped and codoped NaCaPO4 phosphors were prepared by a high-temperature solid-state reaction method. Their VUV–UV excitation spectra, emission fluorescence decay X-ray excited luminescence (XEL), cathodoluminescence (CL) spectra investigated discussed. The main parameters of the electron–vibrational coupling between Eu2+ 5d states host lattice vibrations (such as Huang–Rhys factor, effective phonon energy, position zero-phonon line 4f65d–4f7 Eu2+) estimated from experimental...
Breast cancer (BC) remains a public health dilemma in the world and it is one of leading causes death among women. Trastuzumab kind commonly-used drugs treatment BC, which especially can provide substantial benefits for HER2-positive BC. However, its long-time usage results emergence resistance, cuts down efficacy BC leads to poorer overall survival rate. Hence, attempt this study was investigate how drug resistance enhanced. It has been identified that circHIPK3 could act as an oncogene...
In this paper, we present a modeling study on the discharge characteristics driven by short pulsed voltages, focusing effects of pulse rise rate based fluid description atmospheric plasmas. The numerical results show that breakdown voltage is almost linearly dependent rate, which also confirmed derived equations from model. other words, if fixed as constant, simulation clearly suggest unchanged, although amplitude increases significantly. spatial distribution electric field and electron...
Metabolic reprogramming is a major feature of many tumors including non-small cell lung cancer (NSCLC). Branched-chain α-keto acid dehydrogenase kinase (BCKDK) plays an important role in diabetes, obesity, and other diseases. However, the function BCKDK NSCLC unclear. This study aimed to explore NSCLC.Metabolites serum patients with supernatant cultures were detected using nuclear magnetic resonance (NMR) spectroscopy. Colony formation, proliferation, apoptosis assessed investigate...
Abstract In this study, a two-dimensional fluid model is employed to simulate the streamer, pressure wave, and vortex in surface dielectric barrier discharge driven by nanosecond pulse voltage (ns-SDBD). It comprises numerical with two interconnected modules: dynamics gas flow dynamics. These modules are coupled through physical variables including ‘EHD force’, ‘thermal source’, ‘velocity field’, ‘gas temperature’, pressure’. Our research primarily focuses on underlying mechanisms of waves...
Recent advances in the analysis of proteins have increased demand for more efficient techniques to separate intact proteins. Enhanced-fluidity liquid chromatography (EFLC) involves addition liquefied CO2 conventional mobile phases. The increases diffusivity and decreases viscosity, which inherently leads a separation. Herein, EFLC is applied hydrophobic interaction (HIC) stationary phases first time study impact chromatographic behavior effects on properties, charge state distributions...

The influence of small nitrogen impurities on the uniform barrier discharge at atmospheric pressure in helium is investigated by numerical simulation with a one-dimensional fluid model. results show that different modes completely different. For glow discharge, result breakdown voltage dropping and thus cause decrease charged particle densities current density. In case Townsend can lead to increase density, even change mode, but do not have distinct impact voltage.
Period-doubling and chaos phenomenon have been frequently observed in atmospheric-pressure dielectric-barrier discharges. However, how a normal single period discharge bifurcates into period-doubling state is still unclear. In this paper, by changing the driving frequency, we study numerically transition mechanisms from to using one-dimensional self-consistent fluid model. The results show that before state, it first deviates its operation transforms an asymmetric mode. Then weaker will be...
