A new generation of high power laser facilities will provide laser pulses with extremely high powers of 10 petawatt(PW)and even 100 PW, capable of reaching intensities of 1023 W/cm^2 in the laser focus. These ultra-high intensities are nevertheless lower than the Schwinger intensity IS= 2.3×1029 W/cm^2 at which the theory of quantum electrodynamics(QED) predicts that a large part of the energy of the laser photons will be transformed to hard Gamma-ray photons and even to matter, via electron–positron pair production. To enable the investigation of this physics at the intensities achievable with the next generation of high power laser facilities, an approach involving the interaction of two colliding PW laser pulses is being adopted. Theoretical simulations predict strong QED effects with colliding laser pulses of 10 PW focused to intensities 10^(22) W/cm^2.

Surgical Science 2018年第1期9卷 24-43页

background: Despite increasing survival following damage control laparotomy and open abdomen technique, little is known about the biology of visceral skin graft revascularization and separation from peritoneal contents. Methods: Following laparotomy for trauma, patients with visceral edema preventing fascial closure underwent Vicryl mesh closure followed by visceral split-thickness skin grafting and readmission graft excision and abdominal wall reconstruction. Utilizing laser speckle contrast imaging, immunochemical staining of histologic sections, and RT-PCR array technology, we examined the revascularization, microvascular anatomy, morphology, and change in gene expression of visceral skin grafts. Results: Ten patients ranging in age from 25 to 46 years underwent visceral grafting for cutaneous coverage of an open abdomen. Skin graft perfusion peaked at a mean of 350 PU by post-operative day 14 synchronous with closure of meshed interstices, and remained constant until excision. Time to graft excision ranged from 6 to 18 months. CD-31 immunostaining documented a significant (p = 0.04) increase in vascular surface area in excised grafts compared to control skin. Trichrome staining revealed an 8-fold increase in excised graft thickness. Mesothelial cells were identified within the dermal matrix of excised grafts. RT-PCR demonstrated significant up-regulation of genes involved in matrix structure and remodeling, cytoskeleton regulation, and WNT signaling;and down-regulation of genes involved in inflammation and matrix proteolysis in excised grafts compared to control skin. Conclusion: Our data document early visceral skin graft perfusion and a plateau in revascularization. Histology reveals a robust dermal matrix populated by fibroblasts and mesothelial cells within a complex supporting vascular network. Genetic analysis of excised grafts reveals growth factor, collagen, and matrix remodeling gene expression.
