Reactive-oxygen-species-mediated mechanism for photoinduced antibacterial and antiviral activities of AgPO.

Cubic-shaped AgPO crystals with a mean size of 1 μm were synthesized by a precipitation method from a mixed solution of AgNO, NaHPO, and triethanolamine. The antibacterial activities against , , and DC3000 in both the absence and presence of AgPO under dark conditions and in the presence of AgPO under red-light (625 nm) and blue-light (460 nm) irradiation were examined. The concentrations of reactive oxygen species (ROS) were also measured in the antibacterial action of the AgPO against The photoinduced enhancement of the AgPO antibacterial activity under blue-light irradiation is explained by the formation of ROS during the antibacterial action of the AgPO.

Confined condensation synthesis and magnetic properties of layered copper hydroxide frameworks.

We present a confined condensation technique for the fabrication of layered copper hydroxide frameworks from lamellar copper-organic assemblies with long alkyl chains through the selective introduction of hydroxo bridging ligands. The complete transformations of two different lamellar copper-organic assemblies, Cu(CHSO)·4HO (Cu-DS) and Cu(CHCO)·2HO (Cu-lau), into the corresponding layered copper hydroxide frameworks, Cu(OH)(CHSO) (Cu-OH-DS) and Cu(OH)(CHCO) (Cu-OH-lau), were achieved via confined condensation. The magnetic properties of both lamellar copper-organic assemblies, Cu-DS and Cu-lau, and both layered copper hydroxide frameworks, Cu-OH-DS and Cu-OH-lau, were investigated.

Dual Effect of the Cubic Ag3PO4 Crystal on Pseudomonas syringae Growth and Plant Immunity.

We previously found that the antibacterial activity of silver phosphate crystals on Escherichia coli depends on their structure. We here show that the cubic form of silver phosphate crystal (SPC) can also be applied to inhibit the growth of a plant-pathogenic Pseudomonas syringae bacterium. SPC pretreatment resulted in reduced in planta multiplication of P.

Copper Ion from Cu2O Crystal Induces AMPK-Mediated Autophagy via Superoxide in Endothelial Cells.

Copper is an essential element required for a variety of functions exerted by cuproproteins. An alteration of the copper level is associated with multiple pathological conditions including chronic ischemia, atherosclerosis and cancers. Therefore, copper homeostasis, maintained by a combination of two copper ions (Cu(+) and Cu(2+)), is critical for health.

Lipid-binding properties of TRIM72.

TRIM72 is known to play a critical role in skeletal muscle membrane repair. To better understand the molecular mechanisms of this protein, we carried out an in vitro binding study with TRIM72. Our study proved that TRIM72 binds various lipids with dissociation constants (K(d)) ranging from 88.

Canted antiferromagnetism and spin reorientation transition in layered inorganic-organic perovskite (C6H5CH2CH2NH3)2MnCl4.

This work presents the synthesis, structure determination and magnetic properties of a new complex, phenethylammonium tetrachloromanganate(II), (C(6)H(5)CH(2)CH(2)NH(3))(2)MnCl(4) (Mn-PEA). Single crystals of Mn-PEA were obtained from methanol solution using the solvent-evaporation method at room temperature. The crystal structure of Mn-PEA was determined by single-crystal X-ray diffraction (orthorhombic, space group Pbca, a = 7.

Inorganic-organic chain assemblies as lamellar nanoreactors for growing one-dimensional Cu(OH)2 and CuO nanostructures.

One-dimensional Cu(OH)(2) or CuO nanostructures were fabricated using inorganic-organic chain assemblies, Cu(C(n)H(2n+1)X)(2)·nH(2)O (X = CO(2), SO(4)) as a lamellar nanoreactor, along with NaOH treatment. The shapes and aspect ratios of the Cu(OH)(2) or CuO nanostructures could be varied by adjusting the hydrophobicity of the lamellar nanoreactors.

Bis(2-phenyl-ethyl-ammonium) tetra-chloridocobaltate(II).

Crystals of the title compound, (C(6)H(5)CH(2)CH(2)NH(3))(2)[CoCl(4)], were grown by the solvent-evaporation method. This inorganic-organic hybrid compound exhibits a layered structure in which isolated CoCl(4) inorganic layers alternate with bilayers of phenylethylammonium cations. Although the inorganic anion is zero-dimensional, the layered structure is stabilized via N-H⋯Cl hydrogen bonds.
