PURPOSE: To compare three commercial microbubble contrast agents (Optison, SonoVue, and Levovist) for their effect on gene delivery in skeletal muscle conjunction with the use of therapeutic ultrasound. MATERIALS AND METHODS: The study was approved by Animal Care Use Committee. Plasmid DNA (10 μg) encoding green fluorescent protein (GFP) mixed microbubbles (or saline control) injected into tibialis anterior mice without adjunct ultrasound (1 MHz, 2 W/cm2, 30 seconds, 20% duty cycle)....
A simplified solution procedure is proposed for estimating the dynamic response of a pile group partially embedded in layered saturated soil and subjected to horizontal harmonic loading. In procedure, transfer matrix method first applied solve vibration equation single pile, from which stiffness obtained. The existing lateral displacement half-space introduced build attenuation function, balance passive built accordingly. simple Winkler model used derive pile-soil-pile interaction factor....
Analytical solutions for water inflow and pressure based on steady-state into a circular subsea tunnel in semi-infinite aquifer are deduced depending the rock permeability, drainage at lining, grouting parameters. Based parameters of Qingdao Jiaozhou Bay tunnel, differences between proposed three previous methods analyzed. Comparisons results different verify validity analytical manifest superiorities reflecting effects lining structure seepage problems tunnel. Discussion is also made we...
To understand contamination characteristics and identify sources of heavy metals in soil affected by complex mine activities, a detailed survey from different land cover types was investigated around the Xikuangshan (XKS) antimony south-central China. Soil samples had average concentrations Sb, As, Cd, Cr, Hg, Pb, Cu, Zn Ni exceeding their background level Hunan province. As Cd were main pollutants. A total 86.8% severely polluted, characterized Nemerow's comprehensive index, 68.4% very high...
Abstract The Three Gorges Reservoir Area (TGRA) is characterized by unique geological features that increase its susceptibility to landslides. These slopes are especially prone destabilization when influenced external triggers like rainfall. This research focuses on the Piansongshu landslide within TGRA, aiming at unraveling complex internal deformation mechanisms of landslides triggered rainfall and providing critical insights for their prevention mitigation. study begins with on-site...
Subharmonic imaging (SHI) is a technique that uses the nonlinear oscillations of microbubbles when exposed to ultrasound at high pressures transmitting fundamental frequency ie, fo and receiving half transmit (ie, /2). aided pressure estimation (SHAPE) based on inverse relationship between subharmonic amplitude ambient change.Eight waveforms with different envelopes were optimized respect acoustic power which SHAPE study most sensitive. The was run four input cycles, first in vitro then vivo...
A mathematical formulation is presented to investigate the dynamic response of a single pile embedded in semi-infinite partially saturated soil subjected lateral excitations. An approximate scheme implemented decompose pile–soil system into an extended water–air-filled poroelastic half-space and fictitious pile. The porous medium governed by three-phase elastodynamic theory, whilst treated as beam described conventional one-dimensional vibration theory. By virtue Green's function for set...
Abstract Background: The MADS-box transcription factor myocyte enhancer 2C (MEF2C) is required for the cardiac development and postnatal adaptation in mice-targeted disruption of MEF2C gene results dilated cardiomyopathy (DCM). However, humans, association variation with DCM remains to be investigated. Methods: coding regions splicing boundaries were sequenced 172 unrelated patients idiopathic DCM. available close relatives index patient harboring an identified mutation 300 unrelated,...
Expansive soil has been studied for eighty decades because it is prone to cause geotechnical engineering accidents. The results of the moisture content effects on expansive pressure were not consistent in literatures. In this paper, swelling deformation and tests conducted clarify initial water properties. relation stress was accurately described with a Gaussian distribution, unlike previously published studies. These could be explained by change microstructure diverse contents. addition,...
To investigate the seismic response of large‐scale tunnel in compacted clay and effect shock absorbing layer to tunnel, a series three dimensional (3D) shaking table model tests were carried out. The similarity ratio is 1 : 8 size container 9.3 m (length) × 3.7 (width) 2.5 (height). cross‐sectional diameter 0.9 m, thickness lining 0.06 m. simulate soil surrounding condition, was filled with soil. During tests, concrete strain, acceleration, dynamic pressure on surface measured. results show...
Abstract Unambiguous and rapid sarcosaphagous insect species identification is an essential requirement for forensic investigations. Although some are difficult to classify morphologically, they can be effectively identified using molecular methods based on similarity with abundant authenticated reference DNA sequences in local databases. However, databases still relatively incomplete China because of the large land area distinct regional conditions. In this study, 75 forensically important...
Abstract Landslides are the most widely distributed geological hazards in Three Gorges Reservoir Area (TGRA). Understanding deformation mechanism and evolution of landslides is great significance for their prevention control. In this study, we focused on Zhangjiacitang landslide, a typical bank landslide TGRA. We analyzed relationship between water level fluctuations rainfall, based accumulated displacement monitoring data, to clarify triggering factors mechanism. The results show that...
