بررسی بیان ژن های IL4، TNFα، TGFβ و IFNγ در تائید پلاریزاسیون ماکروفاژهای M1 و M2 حاصل از کشت مونوسیت های انسانی
background: Classical macrophages (M1) and alternative macrophages (M2) are responsible for various functions in order to maintain homeostasis. BCG vaccine and hydatid cyst fluid can be examples of stimulants which can cause M1and M2 macrophage polarization. Evaluating the expression of markers such as IFNγ and TNFα for M1 phenotype and TGFβ and IL4 for M2 phenotype is one of the confirmatory w...
متن کاملPOLARIZATION HYSTERESIS CURVE MEASUREMENT FOR AN Au/PZT/YBCO DEVICE BY DOUBLE PULSE TECHNIQUE
Polarization for Au/Pb(Zr Ti )O /YBa Cu O ferroelectric capacitor has been studied and measured by pulse method. A sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. A value of 25?C/cm2 is measured for the satur...
متن کاملTunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
متن کاملTowards Measurement of Polarization Properties of Skin using the Ellipsometry Technique
Introduction: The human skin is an active medium from the optical point of view. Therefore, the diagnostic and therapeutic techniques employing light are increasing. Current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. Studies have shown that biological tissues, and in particular skin, demonstrate polarization...
متن کاملTheoretical Analysis of Polarization Rotation angle in Dual Reflector Antenna
Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
متن کاملDensity and Polarization Profiles of Dipolar Hard Ellipsoids Confined between Hard Walls: A Density Functional Theory Approach
The density and polarization profiles of the dipolar hard ellipsoids confined between hard walls are studied using the density functional theory (DFT). The Hyper-Netted Chain (HNC) approximation is used to write excess grand potential of the system with respect to the bulk value. The number density is expanded up to zero and first order in polarization to find the results. For the zero order in...
