Purpose: To compare clinical and radiological outcomes between two endoscopically assisted double-button techniques in high-grade acute acromioclavicular separations.
Methods: A retrospective single-center study was conducted in patients with acute acromioclavicular joint dislocation Rockwood types III and V, from 2009 to 2014. All were treated endoscopically, with a 1-year minimum follow-up.
In 1999, we reported new observations that several compounds, including ATP, enhance neurite expression in PC12 cells when coapplied with nerve growth factor (NGF). Because purinergic and NGF signaling have several potential interfaces in PC12 cells, a series of experiments was conducted to elucidate the signal mediators contributing to the enhancement. Activities of selected kinases were measured and Western blots evaluated mitogen-activated protein kinase (MAPK) active and nonactive isoforms in lysates of the treated PC12 cells.

Information has been obtained concerning both the directional properties of the short range correlated moments and the thermal dependence of their spin fluctuation rates.

View Article and Find Full Text PDFA combination of neutron elastic and inelastic, resonant x-ray scattering, and 57Fe Mössbauer experiments are used to determine the unusual magnetic ground state of CeFe2. The complementarities between different time-scale techniques may allow one to understand the dynamic features of the ground state in CeFe2 and its pseudobinary compounds, and how the frustration of Fe tetrahedra leads the appearance of antiferromagnetic fluctuations in the presence of ferrimagnetism. The resulting model can be used to rationalize many of the unusual and conflicting experimental results reported for this material in the literature.
