Cardiovascular, hormone, and lipid responses to stress induced by virtual crane handling.

Objectives: The aim of the study was to test whether a mixed-mock-up-simulator (MMU-simulator) is suitable for on-the-job training by measuring stress reactions induced by handling a crane in a virtual environment in subjects not experienced in crane operation.

Materials And Methods: A MMU-simulator in a virtual environment was developed. Twenty three individuals were randomly divided into Group 1 (n = 13) and Group 2 (n = 10).

Reduction of intimal hyperplasia with Re-188-labeled stents in a rabbit model at 7 and 26 weeks: an experimental study.

The aim of this study was to analyze the feasibility of (188)Re-labeled stents to reduce neointimal formation in a rabbit atherosclerosis model and to test the long-term effects at 7 and 26 weeks. Fifty-nine male New Zealand White rabbits were fed a 0.5% cholesterol diet for 4 weeks before balloon angioplasty and insertion of Palmaz stents in the infrarenal aorta.

Endothelin A receptor antagonist LU 135252 inhibits hypercholesterolemia-induced, but not deendothelialization-induced, atherosclerosis in rabbit arteries.

Rationale And Objectives: The purpose of the study was to test the capability of the endothelin A receptor antagonist LU 135252 to reduce neointimal formation in rabbits after balloon denudation with and without the presence of hypercholesterolemia.

Methods: Twenty-eight male New Zealand White rabbits underwent balloon denudation of the infrarenal aorta. The animals were randomly assigned to 1 of the 4 groups.
