background: mdm2 (murine double minute2) is an oncoprotein that inhibits the p53 activity. overexpression of mdm2 gene has been reported in several human tumors. in the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of mdm2 and susceptibility to breast cancer in a sample of iranian population. methods: this case-control study wa...

let $g$ be a connected graph, and let $d[g]$ denote the double graph of $g$. in this paper, we first derive closed-form formulas for different distance based topological indices for $d[g]$ in terms of that of $g$. finally, as illustration examples, for several special kind of graphs, such as, the complete graph, the path, the cycle, etc., the explicit formulas for some distance based topologica...

in this work, we dissect the performance of  two modern perdew-burke-ernzerhof (pbe)-based double-hybrid (dh) density functionals to predict the isotropic and anisotropic polarizabilities of water nanoclusters (h2o)n [n = 2-6]. the considered models include the cubic integrand (ci) and quadratic integrand (qi) functions as well as the spin-opposite-scaled (sos) scheme for perturbative correlati...

background: sputum smear examination is the basis of diagnosis of tuberculosis and quality control for the correct diagno­sis of tuberculosis is necessary. this study was a method survey and performed with 930 smears with the aim to compare the confidence rate of sputum smear examination reported by one laboratory technician with the findings reported by two techni­cians in a tuberculosis scree...

the goal of this paper is to generalize the recently introduced summability method and introduce double statistical convergence of order  by using ideal. we also investigate certain properties of this convergence.

In this paper, we first define level of tree connectivity for multicast routing schemes in wireless ad hoc networks. Then given the level of tree connectivity, we examine the relation between node density required for single and double tree schemes both analytically and experimentally. For high density wireless ad hoc networks and a given level of tree connectivity, our analysis shows that the ...

BACKGROUND Ectopic pregnancy (EP) is one of the most dangerous complications of pregnancy and without prompt diagnosis and treatment, it could become a major cause of maternal morbidity and mortality. OBJECTIVES In this randomized controlled study, we compared single and double dose of methotrexate (MTX) therapy in the treatment of ectopic pregnancy. PATIENTS AND METHODS This study was perf...
