Influence of Infection on Homografts and Synthetic (Teflon) Grafts

Facile synthesis of colloidal InAs nanocrystals using triphenylarsine as an arsenic source

“…At its melting temperature of 60 1C, its vapor pressure (1.6 Â 10 À 1 Pa) is low enough [22]; thus, it is easier to handle than As(TMS) 3 , whose vapor pressure is 3.3 Â 10 À 1 Pa at 65-71 1C [21]. Also, AsPh 3 is less toxic (LD 50 in rats43200 mg kg À 1 ; 783 mg As kg À 1 [23]) than some other arsenic compounds such as As 2 O 3 (LD 50 in rats¼ 20 mg kg À 1 ; 15 mg As kg À 1 [24]) and AsH 3 (4 h LC 50 in rats¼42.6 ppm [25]). Wang et al reported that InAs NCs could be synthesized using solvothermal techniques by using AsPh 3 as the arsenic source [26,27].…”

Permacol Interposition Graft as an Alternative to Vein in Contaminated Wounds Using a Rabbit Model

“…Before the completion of this process, vein is susceptible to both bacterial invasion and enzymatic breakdown by collagenases. 4,8,19,20 This is reinforced in several studies by noting that the Fig. 4.…”

Bacterial resistance of refrigerated and cryopreserved aortic allografts in an experimental virulent infection model

“…27 The role of preservation techniques have previously been demonstrated. The first experimental studies of Harrison 21 and Foster et al 17 reported the insufficient bacterial resistance of freeze-dried arterial allografts with numerous ruptures. However, Moore et al, 18 in 1974, obtained good bacterial resistance with fresh arterial allografts implanted in vivo.…”

“…20 The efficacy of this technique has been previously demonstrated by creating a retroperitoneum or inguinal abscess. 17,18,21 The abdomen was closed in layers after covering the graft with the retroperitoneum. No adjunct antibiotic or antithrombotic therapy was given to the dogs.…”
