Pentacarbonyl(imidazolidine-2-thione-κS)tungsten(0)

open access: yesActa Crystallographica Section E, 2010
In the title complex, [W(C3H6N2S)(CO)5], the W atom displays an octahedral coordination with five CO molecules and an imidazolidine-2-thione molecule. The W(CO)5 unit is coordinated by the cyclic thione ligand through a W—S dative bond.

Decreased Accumulation of Cyclic Adenosine 3′,5′-Monophosphate in “Ischemic” Skin after 12-0-Tetradecanoyl-phorbol-13-acetate Treatment [PDF]

open access: yes, 1982
The effect of 12-0-tetradecanoyl-phorbol-13-acetate (TPA) on cyclic adenosine 3′,5′-monophosphate (cyclic AMP) level in adult mouse skin in response to ischemia was examined.

Toughness of Confined Auxetic Foams

open access: yesAdvanced Engineering Materials, EarlyView.
Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...

Regulation of gingival epithelial cytokine response by bacterial cyclic dinucleotides

open access: yesJournal of Oral Microbiology, 2019
Background: Cyclic dinucleotides (cyclic di-guanosine monophosphate (c-di-GMP) and cyclic di-adenosine monophosphate (c-di-AMP)) and lipopolysaccharides (LPS) are pathogen-associated molecular patterns (PAMPs).

6-Bromo-2-methylsulfanyl-1,3-benzothiazole

open access: yesActa Crystallographica Section E, 2011
The title molecule, C8H6BrNS2, is almost planar with a dihedral angle of 0.9 (1)° between the benzene and thiazole rings. The values of the geometry-based index of aromaticity (HOMA) and the nucleus-independent chemical shift (NICS ...

Induction of dark-adaptive retinomotor movement (cell elongation) in teleost retinal cones by cyclic adenosine 3,5-monophosphate. [PDF]

open access: yes, 1982
In the teleost retina, the photoreceptors and retinal pigment epithelium (RPE) undergo extensive movements (called retinomotor movements) in response to changes in light conditions and to an endogenous circadian rhythm.

Fate and regulation of anterior-like cells in Dictyostelium slugs [PDF]

open access: yes, 1982
A pattern of two tissue types exists in the Dictyostelium slug. Contained within the posterior tissue are anterior-like cells which comprise about 10% of the developing cell mass.

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

open access: yesAdvanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.
