background: chlorotoxin is a 36-amino acid peptide found in the venom of the leiurus quinquestriatus which blocks small-conductance chloride channels. chlorotoxin binds preferentially to glioma cells that allow development of new methods for the treatment and diagnosis of several types of cancer. thus chlorotoxin derivative was labeled with 131i for further investigation. materials and methods:...

background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...

background: various frequencies of sperm aneuploidy are reported in sperms of subfertile patients compared to normal individuals. moreover, sperm dna damage is shown to be associated with male infertility. in this study, the rate of dna damage and frequencies of aneuploidy in sperms of subfertile patients was investigated. methods: semen samples were obtained from healthy normal and subfertile ...

One of the psychological variables which may have a long-lasting effect on our life is labeling, and students’ accomplishments might be severely undermined through the teacher’s labeling. In spite of this issue, few studies have been carried out on the ramifications of labeling in the educational contexts, in general, and EFL classrooms, in particular. The current study is an attempt to investi...

background: the purpose of study was to evaluate and compare chemical quality of iranian bottled drinking water reported on manufacturer's labeling and standards. methods: this study was a cross-sectional descriptive study and done during july to december 2008. the bottled mineral water collected from shops randomly were analyzed for all parameters address on manufacturer's labeling and the res...

let g=(v,e) be a simple graph. an edge labeling f:e to {0,1} induces a vertex labeling f^+:v to z_2 defined by $f^+(v)equiv sumlimits_{uvin e} f(uv)pmod{2}$ for each $v in v$, where z_2={0,1} is the additive group of order 2. for $iin{0,1}$, let e_f(i)=|f^{-1}(i)| and v_f(i)=|(f^+)^{-1}(i)|. a labeling f is called edge-friendly if $|e_f(1)-e_f(0)|le 1$. i_f(g)=v_f(1)-v_f(0) is called the edge-f...

In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} de...
