A detailed calorimetric study on an epoxy-based nanocomposite system was performed employing bisphenol diglycidyl ether cured with diethylenetriamine as the polymer matrix and a taurine-modified MgAL layered double hydroxide nanofiller.

We have previously reported that nitric oxide (NO) induces apoptosis in MDA-MB-468 cells through its action on the mitochondria and the release of cytochrome c. In this study, we investigated the critical events that must occur after which these cells are committed to apoptosis. We used the long-acting NO donor DETA-NONOate, which, at a concentration of 1 mM, releases NO in the range produced b...

OBJECTIVE We have previously shown that macrophages induce vascular smooth muscle cell (VSMC) apoptosis in vitro by cell-cell proximity and Fas-L/Fas interactions. Because NO is a short-range mediator, we tested whether NO mediates macrophage-induced VSMC apoptosis. METHODS AND RESULTS NO synthase (NOS) inhibitors markedly inhibited macrophage-induced apoptosis of carotid plaque VSMCs (apopto...

The simplest objects with non-commutative multiplication are 2×2 matrices with real entries. Such matrices of determinant one form a closed set under multiplication (since det(AB) = detA · detB), the identity matrix is among them and any such matrix has an inverse (since detA 6= 0). In other words those matrices form a group, the SL2(R) group [7]—one of the two most important Lie groups in anal...

The function of pluripotency genes in differentiation is a matter of investigation. We report here that Nanog and Oct4 are reexpressed in two mouse embryonic stem cell (mESC) lines following exposure to the differentiating agent DETA/NO. Both cell lines express a battery of both endoderm and mesoderm markers following induction of differentiation with DETA/NO-based protocols. Confocal analysis ...

In very-high-energy nuclear collisions, the initial energy of produced gluons per unit area per unit rapidity, (dE/L2)/deta, is equal to f(g(2)&mgr;L) (g(2)&mgr;)(3)/g(2), where &mgr;(2) is proportional to the gluon density per unit area of the colliding nuclei. For an SU(2) gauge theory, a nonperturbative computation of f(g(2)&mgr;L) shows that it varies rapidly for small g(2)&mgr;L but varies...

introduction rhodium metal is known for its stability in corrosive environments, physical beauty, and its unique properties. rhodium is now widely used for alloying platinum in thermocouples, crucibles, evaporating dishes, weighing boats windings for high-temperature furnaces. it has been applied as a coating material because of the hardness and luster of its surface. rhodium is present at abou...
