The platelet-derived microparticles, which carried the sCD40L, accumulated in the apheresis platelet concentrates during the 5 days of storage. They primed the fMLP-activated PMN respiration burst, which might be relative to TRALI.

A diode-pumped picosecond laser was demonstrated with Yb 3+ -doped yttrium lanthanum oxide transparent laser ceramic Yb:(Y 1−x La x ) 2 O 3 (x = 0.1), which was fabricated with nanopowders and sintered in H 2 atmosphere. Passive modelocking was realized for the first time to our knowledge with a semiconductor saturable absorber mirror, generating pulses of 174 ps at the central wavelength 1032.5 nm with the average output power 162 mW under a diode-laser pump power of 3.2 W.

Robust synchronization was achieved in a hybrid configuration for three-color high-repetition-rate ultrashort modelocked lasers around 800, 1030, and 1560 nm due to fractional amplification and enhanced cross-phase modulation. This hybrid synchronization scheme permits the achievements of timing jitter of 550 as between 800-nm and 1030-nm pulses by fractional amplification, and 8.3 fs between the 1030-nm and 1560-nm pulses by cross-phase modulation. The low timing jitter between 800-nm and 1030-nm pulses was commensurate with the broad emission band of the Ti:Sapphire laser.Intensity, arb. units 0.5 1.0
