We first introduce 20 weak forms of continuity, which are closely related to 5 known weak forms of continuity. Then we classify them into 9 groups and give 12 decompositions of continuity. 1. Introduction. Continuity is one of the most important concepts in mathematics. In order to find deep properties of continuity, many weak forms of continuity were introduced in the literature. For instance,...

In the present paper, we rst modify the concepts of weakly fuzzy boundedness, strongly fuzzy boundedness, fuzzy continuity, strongly fuzzy continuity and weakly fuzzy continuity. Then, we try to nd some relations by making a comparative study of the fuzzy norms of linear operators.

An almost-direct product of free groups is an iterated semidirect product of finitely generated free groups in which the action of the constituent free groups on the homology of one another is trivial. We determine the structure of the cohomology ring of such a group. This is used to analyze the topological complexity of the associated Eilenberg-Mac Lane space. 1. Almost direct products of free...

PURPOSE The (131)I-tRRL small peptide probe has been identified in our previous study as a robust tumor molecular radiopharmaceutical that specifically binds to tumor-derived endothelial cells. In this study we developed a smaller structure cyclic tRRL (g2) radiolabeled with (99m)Tc as a novel and optimized peptide probe on tumor angiogenesis molecular imaging. METHODS Both tRRL (g2) and cont...

G1/S and G2/M cell cycle checkpoints maintain genomic stability in eukaryotes in response to genotoxic stress. We report here both genetic and functional evidence of a Gadd45-mediated G2/M checkpoint in human and murine cells. Increased expression of Gadd45 via microinjection of an expression vector into primary human fibroblasts arrests the cells at the G2/M boundary with a phenotype of MPM2 i...

This study was carried out at Sakha Animal Production Research Station, during the period from Oct., 2009 to Sept., 2010. Forty Rahmani ewes were divided into three treatment groups: the 1st, 2nd and 3rd treatment groups were intramuscularly injected (Day 0) with 1 mL GnRH analogue followed by an intramuscular injection with 0.7 mL PGF2α5 (G1), 6 (G2) or 7 (G3) days later. A second dose of 1 mL...

دراین پایان نامه به ارایه روشی ساده و کارآمد به منظور ساخت مدل سطحی هموار با استفاده از تصاویر برش عرضی می پردازیم. در ابتدا با استفاده از تصاویر مقطعی حاصل از دستگاه تصویربرداری اسپکت به ساخت مدل سطحی بزرگترین کره موجود در فانتوم جیسک می پردازیم. سپس روش را بر تصاویر اسپکت بطن چپ قلب انسان اعمال کرده و یک مدل سطحی هموار از سطح خارجی آن به دست می آوریم. در ابتدا به وسیله یک مدل کانتور فعال...

We have previously found that the overexpression of p53 causes G2 arrest and represses the synthesis of cyclin-dependent kinase 1 and cyclin B1, two proteins required for cells to traverse from G2 into M. G2 arrest occurs in response to DNA damage caused by a variety of agents and treatments. Here, we investigate the role of p53 in the G2 arrest that occurs in response to the topoisomerase inhi...

The hypothesis tested is that a 24-h pre-irradiation-exposure of peripheral blood lymphocytes (PBL) to the benzene metabolite hydroquinone (HQ), at doses that are non-acutely toxic (5 microM), induces a less efficient G2-M-checkpoint and enhances the G2-chromosomal radiosensitivity in a statistically significant manner (p<0.01). A less efficient G2-M-checkpoint may allow the transition of damag...

We have characterized a murine IgG monoclonal antibody, OP-G2, specific for platelet glycoprotein (GP) IIb-IIIa (alpha IIb beta 3). OP-G2 Fab fragments inhibit fibrinogen-mediated platelet aggregation and competitively inhibit adenosine diphosphate-induced binding of 125I-fibrinogen to washed platelets. OP-G2 binding to GPIIb-IIIa is specifically inhibited by RGD-containing peptides but not the...
