The molecular signaling events involved in the inhibition of breast cancer cell growth by retinoic acid and interferon-alpha were investigated. All-trans-retinoic acid and interferon-alpha acted synergistically to inhibit growth of both the estrogen receptor-positive breast cancer cell line MCF-7 and the estrogen receptor-negative line BT-20. In MCF-7 cells, all-trans-retinoic acid potentiated ...
Methylglyoxal (MGO) is a reactive dicarbonyl metabolite of glucose, and its plasma levels are elevated in patients with diabetes. Studies have shown that MGO combines with the amino and sulphhydryl groups of proteins to form stable advanced glycation end products (AGEs), which are associated with vascular endothelial cell (EC) injury and may contribute to the progression of atherosclerosis. In ...

In this investigation nickel-cadmium ferrite nanoparticle with stoichiometric composition of Ni0.3Cd0.7Fe2O4 was synthesized by Sol-gel auto- combustion method. In order to study the effect of particle size on physical properties of samples, the powder samples was annealed at temperatures 350, 400, 450 and 500 ○ C for 3h. Structural, morphological and magnetic properties of samples were analyze...
In the structure of the title compound, C(2)H(10)N(2) (2+)·C(8)H(2)Cl(2)O(4) (2-), the dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R(2) (1)(7), R(1) (2)(7) and R(4) (2)(8) associations and extend down the c-axis direction. These ribbons inter-associate down b, giving a two-dimensional sheet structure. In the dianions, one of the carboxyl-ate gr...
Attentional allocation in feature-search mode (W. F. Bacon & H. E. Egeth, 1994) is thought to be solely determined by top-down factors, with no role for stimulus-driven salience. The authors reassessed this conclusion using variants of the spatial cuing and rapid serial visual presentation paradigms developed by C. L. Folk and colleagues (C. L. Folk, R. W. Remington, & J. C. Johnston, 1992; C. ...
