Two-dimensional inorganic nanomaterials have drawnmuch attention due to their excellent properties and wide applications associated with unique 2D structures. However, an efficient and versatile chemical synthesis method using ambient conditions for 2D nanomaterials, especially with secondary structures (e.g. mesopores), has still not been reported. Herein, we report a versatile method to synth...

Conduction in rat peripheral nerve has been monitored following the stimulated release of nitric oxide (NO) from diethylamine-NONOate (DEA-NONOate). Branches of the sciatic nerve were dissected, but left otherwise intact, and propagating signals recorded externally. At levels consistent with inflammation, NO exposure resulted in a complete loss of the compound action potential. Conduction was f...

UNLABELLED BACKGROUND AND OBJECTIVE Regulating protein function in the cell by small molecules, provide a rapid, reversible and tunable tool of metabolic control. However, due to its complexity the issue is poorly studied so far. The effects of small solutes on protein behavior can be studied by examining changes of protein secondary structure, in its hydrodynamic radius as well as its therm...

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...

Decreased nitric oxide (NO) bioavailability is associated with a number of pathological conditions. Administration of a supplemental source of NO can counter the pathological effects arising from decreased NO bioavailability. A class of NO-nucleophile adducts that spontaneously release NO (NONOates) has been developed, and its members show promise as therapeutic sources of NO. Because the NONOa...

In isolated adipocytes, the nitrosothiols S-nitroso-N-acetyl-penicillamine (SNAP) and S-nitrosoglutathione stimulate basal lipolysis, whereas the nitric oxide (NO.) donor 1-propamine, 3-(2-hydroxy-2-nitroso-1-propylhydrazine) (PAPA-NONOate) or NO gas have no effect. The increase in basal lipolysis due to nitrosothiols was prevented by dithiothreitol but not by a guanylate cyclase inhibitor. In ...

We examined the mechanisms by which nitric oxide (⋅ NO) decreased vectorial Na+ transport across confluent monolayers of rat alveolar type II (ATII) cells grown on permeable supports. Amiloride (10 μM) applied to the apical side of monolayers inhibited ∼90% of the equivalent ( I eq) and the short-circuit ( I sc) current, with an half-maximal inhibitory concentration (IC50) of 0.85 μM, indicatin...

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 ...
