Increased skeletal muscle glucose uptake by rosemary extract through AMPK activation.
TLDR
This study is the first to show a direct effect of RE on muscle cell glucose uptake by a mechanism that involves AMPK activation, and it did not affect GLUT4 or GLUT1 glucose transporter translocation in contrast with a significant translocation of both transporters seen with insulin or metformin treatment.

Synthetic model of the asymmetric [Mn3CaO4] cubane core of the oxygen-evolving complex of photosystem II
TLDR
Comparison of the X-ray absorption data with those for the OEC reveal 1 to possess structural parameters that make it a close structural model of the asymmetric-cubane OEC unit, which opens up a new front in the multidisciplinary study of the properties and function of this important biological unit.

The bridging azido ligand as a central “player” in high-nuclearity 3d-metal cluster chemistry
Abstract The chemistry of the azido-bridged coordination clusters continues to attract the intense interest of synthetic inorganic chemists and scientists working in the interdisciplinary field ofExpand
A Mn17 octahedron with a giant ground-state spin: occurrence in discrete form and as multidimensional coordination polymers.
A [Mn(III)(11)Mn(II)(6)(mu(4)-O)(8)(mu(3)-L)(4)](25+) (L = N(3)(-) or OCN(-)) octahedral unit is reported, occurring within 1D (1)(infinity) and 2D (2)(infinity) coordination polymers, as well as theExpand
Initial example of a triangular single-molecule magnet from ligand-induced structural distortion of a [MnIII3O]7+ complex.
TLDR
Ferromagnetic exchange interactions between the three MnIII ions in the nonplanar [MnIII3O]7+ triangular core lead to a spin ground state of S = 6; single-crystal studies reveal the temperature and sweep rate dependent hysteresis loops expected for a single-molecule magnet. Expand
The first cobalt metallacrowns: preparation and characterization of mixed-valence cobalt(II/III), inverse 12-metallacrown-4 complexes.
TLDR
Complexes 1 and 2 are the first Co members in the family of metallacrowns adopting the extremely rare inverse 12-metallac Crown-4 motif. Expand
Ferromagnetic coupling in a 1D coordination polymer containing a symmetric [Cu(mu1,1-N3)2Cu(mu1,1-N3)2Cu]2+ core and based on an organic ligand obtained from the solid state.
TLDR
Density functional calculations reproduce very well the experimental J values and show that ferromagnetism for this complex is mainly due to the topology of the magnetic orbitals and the different coordination spheres of two neighboring Cu(II) atoms, resulting in a small overlap of the orbitals possessing the unpaired electrons. Expand
Transition Metal Single-Molecule Magnets: A {Mn31} Nanosized Cluster with a Large Energy Barrier of ∼60 K and Magnetic Hysteresis at ∼5 K.
TLDR
Compound 1 possesses a unique nanosized structural topology with one of the largest energy barriers reported to-date for high-nuclearity 3d-metal clusters and single-crystal magnetic hysteresis studies reveal the presence of hysteresa loops below 5 K. Expand
Emissive molecular nanomagnets: introducing optical properties in triangular oximato {Mn(III)3} SMMs from the deliberate replacement of simple carboxylate ligands with their fluorescent analogues.
TLDR
Three new emissive SMMs with enhanced photoluminescence properties and potential applications in the field of molecular electronics are reported. Expand
Influence of the Dzyaloshinskii-Moriya exchange interaction on quantum phase interference of spins.
Magnetization measurements of a Mn12mda wheel single-molecule magnet with a spin ground state of S = 7 show resonant tunneling and quantum phase interference, which are established by studying theExpand
