A comparison of para-anastomotic compliance profiles after vascular anastomosis: nonpenetrating clips versus standard sutures.

Purpose: Anastomotic compliance is an important predictive factor for long-term patency of small diameter vascular reconstruction. In this experimental study we compare the compliance of continuous and interrupted sutured vascular anastomoses with those using nonpenetrating clips.

Methods: Both common carotid arteries in nine goats (average weight, 57 +/- 5.

The mechanical behavior of vascular grafts: a review.

The development of intimal hyperplasia (IH) near the anastomosis of a vascular graft to artery is directly related to changes in the wall shear rate distribution. Mismatch in compliance and diameter at the end-to-end anastomosis of a compliant artery and rigid graft cause shear rate disturbances that may induce intimal hyperplasia and ultimately graft failure. The principal strategy being developed to prevent IH is based on the design and fabrication of compliant synthetic or innovative tissue-engineered grafts with viscoelastic properties that mirror those of the human artery.

Comparison of the antimicrobial capability of an abrasive paste and chemical-soak denture cleaners.

The objective of this research was to compare the ability of the two most popular methods for denture cleaning to remove plaque microorganisms from dentures. Dentu-Creme abrasive denture paste and Efferdent alkaline peroxide denture-cleanser soak were selected for study. Two trials were completed in which these materials were used alone and in combination along with a no-treatment control to determine the level of recoverable plaque bacteria from removable dentures.

Enterotoxin synthesis by nonsporulating cultures of Clostridium perfringens.

Chemostat-cultured Clostridium perfringens ATCC 3624 and NCTC 10240, and a nonsporulating mutant strain, 8-5, produced enterotoxin in the absence of sporulation when cultured in a chemically defined medium at a 0.084-h-1 dilution rate at 37 degrees C. The enterotoxin was detected by serological and biological assays.
