BACKGROUND Septic shock is common and has unacceptably high morbidity, mortality, and associated cost with numerous failed attempts at developing effective therapies. Endotoxin, one of the most potent mediators of sepsis, is found in high levels in approximately 50% of patients with septic shock. Polymyxin B (PMX) hemoperfusion has been shown in numerous studies to successfully remove endotoxin...
Background: Fluid resuscitation is the mainstay of treatment to counteract massive plasma leakage in dengue shock syndrome. We aimed to determine the differences in clinical outcomes and hemodynamic parameters of children with dengue shock syndrome post restrictive and liberal fluid resuscitation. Materials and Methods: A retrospective observational study of pediatric patients who were betwee...
The time dependent neutrino oscillation signals due to the passage of a shock wave through the supernovae are analyzed for the case of three active neutrinos and also for the case that there are two additional sterile neutrinos. It is shown that, even without flavour identification and energy measurement, detailed information about the masses and mixing angles of the neutrinos may be obtained w...
The present study investigates the effects of low-energy defocused extracorporeal generated shock waves on collagen structure of cellulite afflicted skin. Cellulite measurement using high-resolution ultrasound technology was performed before and after low-energy defocused extracorporeal shock wave therapy (ESWT) in 21 female subjects. ESWT was applied onto the skin at the lateral thigh twice a ...
The use of echocardiography in the intensive care unit for patients in shock allows the accurate measurement of several hemodynamic variables in a noninvasive way. By using echocardiography as a hemodynamic monitoring tool, the clinician can evaluate several aspects of shock states, such as cardiac output and fluid responsiveness, myocardial contractility, intracavitary pressures, and biventric...
There is currently little feedback as to whether kidney stones have fractured during shock wave lithotripsy. Resonant scattering of the lithotripter shock wave was used here to differentiate intact and fractured stone models in water. Scattering, including reflection and radiation due to reverberation from within the stone, was calculated numerically with linear elasticity theory and agreed wel...
The compact Wedge Range Filter (WRF) proton spectrometer was developed for OMEGA and transferred to the National Ignition Facility (NIF) as a National Ignition Campaign diagnostic. The WRF measures the spectrum of protons from D-(3)He reactions in tuning-campaign implosions containing D and (3)He gas; in this work we report on the first proton spectroscopy measurement on the NIF using WRFs. The...
Monitoring shock propagation through the bulk of an opaque solid has a strong impact in study both wave physics and warm dense matter, but requires large, high-brilliance x-ray facilities. This Letter demonstrates that such measurement can also be performed using counterpropagating ultrasonic plane wave: As modulates medium during propagation, scattering occurs when two waves collide. The spati...
A building or a bridge might collapse after heat shock. This paper shows that porous hierarchy of coating can effectively prevent from such damage. cocoon’s geometrical structure is studied and its resistance to the shock revealed by thermal oscillator. The theoretical model reveals an extremely low frequency oscillator, which very important for cocoons’ biomechanism, especially in insulation f...
This manuscript presents a method to calculate and analyze mechanical shock of multi-rigid body system, based on the revised concept center percussion newly derived variable called radius percussion. The objective is improve mechanism’s robustness against shocks that are caused by certain impacts, such as those experienced legged robots from landing jump or making step. In practice, it can be u...
