An intrinsic correlation between the atomic clusters and the primary phases has been revealed. It is found that there are topological icosahedral

short-range orders (ISROs) in the as-cast sample in addition to fcc-Zr2Ni-type chemical SROs. These topological ISRO and fcc-Zr2Ni-type chemical SRO can simultaneously quasicrystallize/crystallize into the corresponding nanoscaled icosahedral quasicrystalline phase (I-phase) and fcc-Zr2Ni crystal as primary products during crystallization. The synchronic precipitation of these two metastable phases can be understood in terms of their structural similarity between Selleck HIF inhibitor the fcc-Zr2Ni and I-phase in local atomic configuration. In comparison with fcc-Zr2Ni crystal, the I-phase has a smaller size and lower volume fraction due to its lower growth rate attributed to its more

Caspase cleavage complex composition and higher structural symmetry. The competitive growth between these two phases results in the development of nanostructured materials in this alloy after annealing. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3525985]“
“The aim of this study was to investigate the impact of retropubic injection of 0.125% bupivacaine during midurethral sling placement on postoperative

pain.

A randomized, double-blind trial of 42 women undergoing midurethral sling for stress incontinence was conducted. The intervention group received an injection of 0.125% bupivacaine in the retropubic space prior to midurethral sling placement, while the control group received no injection. Pain scores were recorded via a 10-cm visual analog scale at 2, 6, and 24 h postoperatively.

Pain scores were lower in the bupivacaine group compared to the control group at 2 h MX69 order (1.9 versus 2.6, p = 0.05). Mean pain scores were similar at all other time points (all p > 0.45). Participants in both groups used similar amounts of pain medication in the hospital, except that patients in the bupivacaine group used more PO non-steroidal anti-inflammatory drugs (p = 0.047).

Retropubic injection of 0.125% bupivacaine at the time of midurethral sling placement decreases short-term postoperative pain.
