Generation of an inflammatory response is a complex process involving multiple factors acting in parallel and in concert. Viruses, parasites, and bacteria, particularly lipopolysaccharide (LPS), a component of the cell wall of gram-negative bacteria, act cooperatively with the cytokine interferon (IFN)-gamma to induce many of the genes involved in inflammation. In addition, these components syn...

We calculate the decay rates for $\eta_c \to \gamma \gamma$, $J/\psi \eta_c$ and \eta_c e^+e^-$ in lattice QCD with $u$, $d$, $s$ $c$ quarks sea first time. improve significantly on previous theory calculations to achieve accuracies of 1--2\%, giving results that are now more accurate than experimental values. In particular our transform theoretical picture $\eta_c\to\gamma\gamma$ decays. use g...

Interferons have the ability to enhance or diminish the expression of specific genes and have been shown to affect the proliferation of certain cells. Here, the effect of gamma-interferon on fetal hemoglobin synthesis by purified cord blood, fetal liver, and adult bone marrow erythroid progenitors was studied with a radioligand assay to measure hemoglobin production by BFU-E-derived erythroblas...

Human chromosomes 6 and 21 are both necessary to confer sensitivity to human interferon gamma (Hu-IFN-gamma), as measured by the induction of human HLA class I antigen. Human chromosome 6 encodes the receptor for Hu-IFN-gamma, and human chromosome 21 encodes accessory factors for generating biological activity through the Hu-IFN-gamma receptor. A small region of human chromosome 21 that is resp...

Hue provides a useful and intuitive cue that is used in a variety of computer vision applications. Hue is an attractive feature as it captures intrinsic information about the colour of objects or surfaces in a scene. Moreover, hue is invariant to confounding factors such as illumination brightness. However hue is not stable to all of the types of confounding factors that one might reasonably en...

Background: Background gamma radiation levels vary in different locations and depended on many factors such as radiation properties of soil, building materials as well as construction types which human lives on it. People are always exposed to ionizing radiation, which could badly influence their health. The aim of this study was to evaluate the background gamma-ray dose rate and the estimated ...

The aerial measuring terrestrial gamma radiation from airborne platforms is a useful method for characterizing the radiation levels over large areas. Because of the advantage of Monte Carlo method, it is very suitable for simulation of gamma ray transport and interaction with media (soil, air, aircraft and detector), which offer alternative means of estimating detector response and calibration ...

The Th1-derived cytokine gamma interferon, IFN-gamma, is present within the microenvironment of an atheromatous lesion and likely contributes to lesion progression through macrophage activation. While the inflammatory effects of IFN-gamma are well known, the role of this cytokine in cholesterol metabolism in macrophage derived foam cells is unclear. In the present study, the incubation of foam ...

Many sera from normal individuals as well as patients with various disease states contain agglutinating antibodies which show specificity for antigenic determinants of gamma-globulin revealed by pepsin digestion at pH 4.1. Sera containing such agglutinating activity as well as sera negative for these agglutinators contain low molecular weight (3S-5S) components of slow gamma-mobility which inhi...

the aim of this study was to determine feasibility of gamma irradiation in broiler chicks’ diet and scrutiny of productive performance of broiler due to gamma irradiated diets. there were 256 broiler chicks (male and female) from arian strain. experiment was statistically analyzed using balanced complete randomized design with four factors (including four irradiation doses: 0, 6.7, 7.7 and 8.7 ...
