Background and Objectives: A sudden jump in blood demand during natural disasters may have strong negative impact on the performance of blood supply chain. Appropriate response to emergency situations requires predictive approach to determining the optimal allocation of blood supply chain resources for various disaster scenarios. The present study, thus, presents an optimization model aimed at ...

objective(s):in previous investigations, we have shown para-nonylphenol (p-np) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (mscs) in vitro. in this study, we first treat the rats with p-np, then carried out the biochemical and morphological studies on mscs. materials and methods: proliferation property of cells was evaluated with t...

In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...

Jahiel, R. I. (Cornell University Medical College, New York, N.Y.), and E. D. Kilbourne. Reduction in plaque size and reduction in plaque number as differing indices of influenza virus-antibody reactions. J. Bacteriol. 92:1521-1534. 1966.-The serological reactivity of an antigenically hybrid influenza virus recombinant (X-7) was studied in a heteroploid cell plaquing system in which antisera to...

Hussein Hollands, MD, MS (epid) Peter J. Kertes, MD, CM, FRCS(C) The purpose of this review article is to outline a few concepts that are useful for interpreting the results of a randomized clinical trial (RCT). Specifically, we will focus on measures of the size of a treatment effect— relative risk ratio (RRR), absolute risk ratio, and number needed to treat (NNT). These concepts are important...

Physicians, patients and policy-makers are influenced not only by the results of studies but also by how authors present the results. Depending on which measures of effect authors choose, the impact of an intervention may appear very large or quite small, even though the underlying data are the same. In this article we present 3 measures of effect — relative risk reduction, absolute risk reduct...

the main concern of the present study was to compare the frequency of the use of semantic adjustment strategies in versed and free-verse styles in the english translations of hafez poetry. the focus of the comparison was the number of expansion and reduction strategies employed in these translations. the corpus of the study comprised two translations of hafez poetry; one was a versed translatio...

background: around one out of two mothers give births by cesarean section (cs) surgery in iran and about half of this number is due to previous cs. recently health sector evolution (hsep) program (started in april 2014) targets the high rate of cs in iran. to assess the impact of the interventions, we emphasized that the first birth cesarean (fbc) proportion is one of the main indicators to ass...

Background and Aims: This study aimed to observe the effect of Icariin on histomorphometric changes of testis and prostate induced by Acrylamide. Materials and Methods: Male mice were divided into four groups (n=8): A is the control group and does not get any treatment, B is the sham group and only received drinking water. C group received Acrylamide 10 mg/kg. D group received Acrylamide 15 mg...
