OBJECTIVE Following the Ross operation, pulmonary autografts tend to dilate over time. This study researches the fate of the pulmonary autograft - at 4.5 years following the modified Ross operation - with special reference to the impact of the modification on (a) pulmonary autograft dilatation, (b) the neo-aortic root geometry, (c) neo-aortic valve function and (d) the coronary artery reserve. ...

BACKGROUND The Ross/Ross-Konno procedure is considered a good option for irreparable aortic valve disease in pediatric patients because of its hemodynamic performance and potential for growth of the pulmonary autograft. This study is a review of the long-term results of our 20-year experience with the Ross and Ross-Konno operations in a single institution. METHODS Between June 1995 and Januar...

Studies delineating the dietary Val needs of modern commercial broilers are sparse. Three studies were conducted to determine the dietary Val nutrient needs of Ross x Ross 308 male broilers. Three time periods were evaluated independently, 0 to 14 d (starter), 14 to 28 d (grower), and 28 to 42 d (finisher) of age. Corn- and peanut meal-based diets for each feeding phase served to titrate the Va...

The introductory chapter by Don Ross and Harold Kincaid does a superb job of describing the current orientation of philosophy of economics, the result of developments in philosophy of science, in economics, and in the relationsh...

When replacement of the aortic valve in neonates and infants is required, Ross-Konno procedure provides a high-quality left ventricular outflow with good mid-term durability. The procedural outcome highly dependent on pre-procedural condition neonate or infant. Most series contain substantial numbers post-balloon valvotomy patients as emergent urgent management severe, acute regurgitation. In c...
