The study was performed to investigate the possible neuroprotective role of palmatine, a protoberberine alkaloid against aluminum-induced aberration in neurotransmitter levels, excitotoxicity, neuronal inflammation, damage, and degeneration. 100 mg/kg aluminum chloride served as inducing agent administered orally male Wistar albino rats for 42 consecutive days. Animals were divided into four gr...

OBJECTIVES This study investigated the possible interactions between three addition silicone materials (Express®, Aquasil Ultra® and Adsil®), three hemostatic agents (ferric sulfate, StatGel FS®; aluminum sulfate, GelCord®; and aluminum chloride, Hemostop®) and gingival retraction cords previously handled with latex gloves to determine whether direct contact with medicaments or indirect contami...

In the title compound, C16H19ClN4O3, the cyclo-hexane ring displays a chair formation and the tetra-hydro-pyridine ring displays an envelope conformation with the methyl-ene C atom as the flap; the imidazolidine ring also displays an envelope conformation with a methyl-ene C atom as the flap. In the crystal, O-H⋯N hydrogen bonds between hy-droxy groups and pyridine rings link inversion-related ...

The title compound, C(8)H(10)NO(2) (+)·H(2)PO(4) (-), is a derivative of the naturally occurring compound methyl-anthranilate. The asymmetric unit comprises the 2-(methoxy-carbon-yl)anilinium cation and the dihydrogen phosphate anion. In the cation, the dihedral angle between the benzene ring plane and that through the methyl ester substituent is 22.94 (9)°. In the crystal, adjacent cations and...

The title compound, C(14)H(15)FO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-fluoro-3-isopropyl-sulfanyl-7-methyl-1-benzofuran-2-yl)acetate. In the crystal, mol-ecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by weak C-H⋯O hydrogen bonds.

density functional (dft) calculations at m05-2x/aug-cc-pvdz level were used to analyze the interactions between dimethyl sulfoxide (dmso) dimers. the structures obtained have been analyzed with the atoms in molecules (aims) and natural bond orbital (nbo) methodologies. four minima were located on the potential energy surface of the dimers. three types of interactions are observed, ch•••o, ch•••...

The title compound, C(10)H(12)N(3)O(+)·Cl(-), is a derivative of o-phthaldehyde and methyl-thio-urea. The mol-ecules form dimers through intra- and inter-molecular N-H⋯O hydrogen bonds. The dimers are further linked into chains through one C-H⋯Cl and two N-H⋯Cl hydrogen bonds.

Condensed octadecylphosphonic acid (OPA) dimers, i.e., two OPA molecules combined with the loss of a water molecule, were detected by time-of-flight secondary ion mass spectrometry (TOF-SIMS) on OPA self-assembled monolayers (SAMs) that are only weakly bonded on the native oxide layer of a silicon wafer. In contrast, these condensed dimers were absent on OPA SAMs formed on the oxide layer of an...

Previous studies suggest that magnesium chloride may have discriminative stimulus effects that partially overlap with those of noncompetitive N-methyl-D-aspartate antagonists as well as certain monoamine uptake inhibitors. In our study, rats were trained to discriminate 100 mg/kg magnesium chloride from saline and its discriminative stimulus effects were characterized with respect to N-methyl-D...

In this paper, the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale, because of its analogous chemical composition to C-S-H. Aluminum incorporation in C-S-H and...
