Abstract The proper allocation/distribution of limited resources is a traditional problem with various applications. mathematical formulation such problems usually includes constraints describing the set feasible solutions ( ), from which (nearly) optimal or equilibrium solution should be selected. Often more difficult to determine than find solution. Alternatively, already known often makes it...

immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (hsp), fibroblast growth factors (fgf) and transferrin receptors (tf-r) in 22 samples of p...

objective(s): prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (nahs) but effect of nahs on mrna expression of prostaglandin e2 receptors (ep1, 3-4; eps) has not been investigated. therefore, this study designed to evaluate the effect of nahs on mrna expression of eps receptors in response to mucosal acidification and distention-induced gastric acid ...

conclusions expression of armc3 in tumor samples and normal adjacent tissue is very important. the expression of this gene in tumor-adjacent tissue may be associated with the stage of cancer; it may be that these tissues are affected by epigenetic and oncogenic changes of breast cancer. accordingly, aberrant expression of armc3 in tumor samples may be an attractive candidate for use as a tumor ...

Background With the continuous discovery of microRNA's (miRNA) association with a wide range of biological and cellular processes, expression profile-based functional characterization of such post-transcriptional regulation is crucial for revealing its significance behind particular phenotypes. Profound advancement in bioinformatics has been made to enable in depth investigation of miRNA's role...

This equation expresses U2 as the ratio of two positive definite integrals. Accordingly, the solution is stable; moreover, it can be shown that equation (25) providesthe basis for a variational method of determining u2. The explicit solution of the underlying problem in hydromagnetic oscillations in case the prevailing fields are axisymmetric has many interesting features. They will be discusse...

background: asthma is very common in children and its diagnosis is based on clinical manifestations, which can be misdiagnosed as other respiratory diseases with similar signs and symptoms. objective: to analyze the expression of st2l and cd203c in the diagnosis of pediatric asthma. methods: basophils were purified from whole blood samples of patients and healthy controls using ficol-paque grad...

Background and Aim: P. aeruginosa exotoxins are responsible for pathogenicity and antibiotic resistant. The aim of this study was to investigate the effects of the Ammi. visnaga (A. visnaga) extract on the P. aeruginosa exotoxin A and S genes expression. Materials and Methods: Antibacterial effects of the A. visnaga ethanolic extract were performed using the micro dilution technique in sequent...

In this paper‎, ‎we study the extremal‎ ‎ranks and inertias of the Hermitian matrix expression $$‎ ‎f(X,Y)=C_{4}-B_{4}Y-(B_{4}Y)^{*}-A_{4}XA_{4}^{*},$$ where $C_{4}$ is‎ ‎Hermitian‎, ‎$*$ denotes the conjugate transpose‎, ‎$X$ and $Y$ satisfy‎ ‎the following consistent system of matrix equations $A_{3}Y=C_{3}‎, ‎A_{1}X=C_{1},XB_{1}=D_{1},A_{2}XA_{2}^{*}=C_{2},X=X^{*}.$ As‎ ‎consequences‎, ‎we g...
