conclusions: in neonates and infants with primary diagnosis of sepsis, hsv infection should be considered especially if the clinical condition does not improve after 48 hours of antibiotic therapy, and sepsis still exists with elevated liver enzymes. results: among 150 neonates and infants younger than 3 months old with sepsis, the pcr results for detecting the hsv dna, were positive in 6 sampl...

in this research, dried acetone:chloroform extract of aerial parts of e. denticulata as one of the endemic plants to iran, afforded a number of triterpenes and steroids including: betulin, 24-methylene-cycloart-3-ol, cycloart-23z-ene-3β,25-diol, cycloart-23z-ene-3β,25-diol, ergosta-8,24-dien-3-ol (obtusifoliol) and beta-sitosterol which were reported for the first time from this plant. the stru...

abstract        background and objective: herpes simplex encephalitis is a life-threatening consequence of the central nervous system (cns) infection with herpes simplex virus (hsv). although it is a rare disease, mortality rates reach 70% in the absence of therapy and only a minority of individuals can return to normal function. the aim of this study was to determine possible correlation betwe...

background and objectives: encephalitis can cause a severe public health problem. the main aim of this research was to evaluate the medical laboratory results of patients with herpes simplex virus (hsv) encephalitis. materials and methods: diagnosis of encephalitis for these patients was firstly based on a clinical profile for herpes simplex encephalitis (hse), plus either a detected hsv1&2-dna...

background pcr is a molecular technique for herpes simplex virus (hsv) detection that can cause life-threatening infections such as encephalitis and keratitis. however, the main issues, false-negative results causing by pcr inhibitors, of this technique that reduce pcr efficiency. to overcome this problem, a competitive internal amplification control (iac) was constructed for conventional pcr u...

background: herpes simplex virus (hsv) is a member of herpesviridae and a leading cause of human viral diseases. meningitis occurs as a complication of hsv-1 or hsv-2 primary infection. objectives: we aimed to evaluate hsv meningitis in children in gorgan province, iran. patients and methods: forty-five cerebrospinal fluid samples were taken from children referred with meningitis symptoms. samp...

background patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. the risk of transfusion-transmitted viral infection is well known in these patients. however, there is dearth of information about the seroprevalence of herpes simplex virus (hsv) infection in patients with beta thalassemia in li...

it is well known that in operations research‎, ‎degeneracy can cause a cycle in a network‎ ‎simplex algorithm which can be prevented by maintaining strong‎ ‎feasible bases in each pivot‎. ‎also‎, ‎in a network consists of n arcs‎ ‎and m nodes‎, ‎not considering any new conditions on the entering‎ ‎variable‎, ‎the upper bound of consecutive degenerate pivots is equal‎ $left( ‎begin{array}{c}‎ ‎n...

A discrete statistical model is a subset of probability simplex. Its maximum likelihood estimator (MLE) retraction from that simplex onto the model. We characterize all models for which this rational function. This contribution via real algebraic geometry rests on results Horn uniformization due to Huh and Kapranov. present an algorithm constructing with MLE, we demonstrate it range instances. ...

Abstract This article focuses on solving the fuzzy transportation problem using dual approach of simplex. method uses a strong ranking technique for iterative values trapezoidal numbers within problem. Because approach, (in which cost, demand, and supply appear as numbers) is transformed into crisp valued LPP (Linear Programming Problem) employed simplex procedure solving. The earlier task obta...
