Optics letters

Bowes BT, Langhoff H, Downer MC, Wilcox M, Hou B, Nees J, Mourou G.
PMID: 16419896
Opt Lett. 2006 Jan 01;31(1):116-8. doi: 10.1364/ol.31.000116.

Using femtosecond microscopy, we observe subpicosecond transport of thermal energy radially outward from a micrometer-sized spot of an aluminum target following P-polarized excitation at >10(18) W/cm2 with a 24 fs pulse. The rapid expansion coincides with the onset of...

Promising role of drug-coated balloons in the tibial vessels?.

The Journal of cardiovascular surgery

Langhoff R, Behne A, Buschmann EE.
PMID: 27332681
J Cardiovasc Surg (Torino). 2016 Jun 22; Epub 2016 Jun 22.

To judge on the role of drug-coated balloons (DCB) in below-the-knee (BTK) artery interventions, we analyzed randomized trials which compare coated to non-coated balloons and additionally a direct comparison of drug-eluting stents (DES) with DCB. As angioplasty with non-coated...
