Tracheal cryopreservation: caspase-3 immunoreactivity in tracheal epithelium an...
Sotres-Vega,A.; Baltazares-Lipp,M.; Villalba-Caloca,J.; Gaxiola-Gaxiola,M.O.; Santibañez-Salgado,J.A.; Olmos-Zúñiga,J.R.; Jasso-Victoria,R.Cryopreservation has an immunomodulating effect on tracheal tissue as a result of class II antigen depletion due to epithelium exfoliation. However, not all epithelium is detached. We evaluated the role of apoptosis in the remaining epithelium of 30 cryopreserved tracheal grafts. Caspase-3 immunoreactivity of tracheal epithelium was studied in canine tracheal segments cryopreserved with F12K medium, with or wit...
Hadronic shower development in Iron-Scintillator Tile Calorimetry
Amaral, P.; Amorim, A.; Anderson, K.; Barreira, G.; Benetta, R.; Berglund, S.; Biscarat, C.; Blanchot, G.; Blucher, E.; Bogush, A.; Bohm, C.; Boldea, V.The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter presents a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behaviour is obtained. The underlying radial energy densities for the four depth...
