The purpose of this paper is to solve two types of Lyapunov equations and quadratic matrix equations by using the spectral representation. We focus on solving Lyapunov equations $AX+XA^*=C$ and $AX+XA^{T}=-bb^{T}$ for $A, X in mathbb{C}^{n times n}$ and $b in mathbb{C} ^{n times s}$ with $s < n$, which $X$ is unknown matrix. Also, we suggest the new method for solving quadratic matri...
Background: Determining the etiologic causes of septic arthritis is of the most importance. Goal of this study was to investigate presence of staphylococcal enterotoxins A, B, C and Toxic Shock Staphylococcal toxin-1 in the synovial fluid of patients with arthritis. Methods: This cross-sectional study was performed in the Pediatric and Orthopedic Wards of Hazrat Rasoul Hospital in Tehran, Iran...
cyclooxygenase-2 (cox-2) has a pivotal role in the pathogenesis of the lung cancer. it is known that cox-2 negatively regulates the activity of a number of tumor suppressors, including p53. consequently, inhibition of cox-2 signaling is anticipated to be a promising approach to stabilize p53 functionality. in this regard, we investigated the effect of cox-2 signaling blockade on p53 and cox-2 e...
antimicrobial resistance is one of the most severe threats to human health. the first report of plasmid-mediated colistin resistance in escherichia coli from animals, food, and humans was in 2015 from china. the current increasing trend of resistance is extremely troubling because polymyxins are the last-resort antibiotics for treating infections with carbapenem-resistant enterobacteriaceae.
introduction: interleukin-2 (il-2) as a t helper type 1 (th1) cytokine has an important role background and objective: interleukin-2 (il-2) as a t helper type 1 (th1) cytokine has an important role in activation, growth and differentiation of several immune cells. moreover il-2 is known as a pro-inflammatory and anti-tumoral cytokine. in addition deysregulation of il-2 in some diseases such as ...
The decays B + c → J/ψ D + s and B + c → J/ψ D * + s are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb −1 of pp collisions collected at centre-of-mass energies √ s = 7 TeV and 8 TeV, respectively. Signal candidates are identified through J/ψ → μ + μ − and D (*)+ s → φπ + (γ /π 0) decays. With a two-dimensional likelihood f...
new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...

بمنظور ارزیابی کشت مخلوط ذرت (zea mays l.) و لوبیا (phaseolus vulgaris l.) آزمایشی در قالب طرح بلوکهای کامل تصادفی با 11 تیمار و سه تکرار اجرا گردید. تیمارهای آزمایش شامل کشت مخلوط تراکم معمول ذرت(c) با تراکم معمول لوبیا(b) باضافه 10%،20 % و30% {b(c+30%c),b(c+20%c),b(c+10%c)} ، کشت مخلوط تراکم معمول لوبیا(b) با تراکم معمول ذرت(c) باضافه 10%، 20% و 30% {b(c+30%), b(c+20%),b(c+10%)} کشت مخلوط ترا...
elevated expression of the drug efflux transporter abcg2 seems to correlate with multidrug resistance of cancer cells. specific cox-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. to clarify whether abcg2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of abcg2 in breast cancer cell lines ...
