cancer is considered as a challenging deathly disease and discovering or synthesis of new cytotoxic agents is a worldwide attempt. in this study, a group of recently synthesized chalcones, with the structure of 1,3-diarylprop-2-en-1-one having differesnt cox-1 and/or cox-2 selectivities, have been examined on human hepatocarcinoma (hepg2), lung carcinoma (a549), and breast adenocarcinoma (mcf-7...

background: cucumber mosaic virus (cmv) from the bromoviridae family, is one of the most widespread plant viruses in the world. objectives: in the present study tomato fields in guilan, isfahan, khorasan razavi, khuzestan and tehran provinces were surveyed to determine the presence of cmv subgroups during 2011-2012. materials and methods: out of 305 symptomatic leaf samples tested by enzyme-lin...

groups of infinite rank in which every subgroup is either normal or self-normalizing are characterized in terms of their subgroups of infinite rank.

abstract. in this paper we study some relations between the power andquotient power graph of a finite group. these interesting relations motivateus to find some graph theoretical properties of the quotient power graphand the proper quotient power graph of a finite group g. in addition, weclassify those groups whose quotient (proper quotient) power graphs areisomorphic to trees or paths.

We construct some nonsmoothable actions of Z2×Z2 on spin four-manifolds by using an equivariant version Furuta's 10/8-inequality. The examples satisfy following property: any proper subgroup is smoothable for smooth structure.

We study the mirror symmetry on singular locus of Hitchin system at two levels. First, by covering it (supports of) (BBB)-branes, corresponding to Higgs bundles reducing their structure group Levi subgroup some parabolic P, whose conjectural dual (BAA)-branes we describe. Heuristically speaking, latter are given unipotent radical P. Second, when P is a Borel subgroup, able construct family hype...

Background and Aim: There is a gap of information on the effect of time, disinfectant, and storage conditions on the dimensional stability of direct post patterns made of self-cure acrylic resins. This study assessed the effect of Deconex® and wet or dry stor-age conditions on the dimensional stability of post patterns made of Duralay and GC acrylic resins. Materials and Methods: Sixty spe...

Statistical findings on subgroups belong to the most popular and simple forms of knowledge we encounter in all domains of science, business, or even daily life. We are told such messages as: Unemployment rate is overproportionally high for young men with low educational level, young poor women are infected with AIDS at a much higher rate than their male counterparts, lung cancer mortality rate ...
