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 ...
Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) is a widespread method for metabolic labeling of cells and tissues in quantitative proteomics; however, incomplete incorporation of the label has so far restricted its wider use in plants. Here, we argue that differential labeling by two different versions of the labeled amino acids renders SILAC fully applicable to dark-grown plant...
Green fluorescent protein (GFP) and its derivatives are the most widely used molecular reporters for live cell imagining. The development of organelle-specific fusion fluorescent proteins improves the labeling resolution to a higher level. Here we generate a R26 dual fluorescent protein reporter mouse, activated by Cre-mediated DNA recombination, labeling target cells with a chromatin-specific ...

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...
introduction: obstructive cholestasis is associated with overproduction of endogenous opioids (eop) ,nitric oxide (no) and cytokines in the blood stream. these consequences can affect sex hormones. sincefertility is a result of physiological balance of sex hormones, we investigated the relationship betweenobstructive cholestasis and sex hormones and apoptotic germ cells in adult male rats. mate...
