The yield of carcass parts as well as levels of carcass fat, moisture, and ash were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) and in the Ross 308 commercial broiler, when fed diets that were representative of those being fed during 1957 and 2001. The Ross 308 was used to represent 2001 commercial broilers. Comparisons of carcass weights of the Ross 308 on the 2001 diet ver...

BACKGROUND The most appropriate valve substitute at aortic valve replacement (AVR) for young female adult patients wanting to have children is unclear. METHODSANDRESULTS Between 1992 and 2013, 12 consecutive female patients aged >18 (median, 22.5 years; range, 18-34 years) underwent Ross operation (Ross group). Between 1984 and 2013, 9 consecutive female patients aged >18 (median, 30 years; r...

The spatial and temporal variations of Ross River virus infections reported in Queensland, Australia, between 1985 and 1996 were studied by using the Geographic Information System. The notified cases of Ross River virus infection came from 489 localities between 1985 and 1988, 805 between 1989 and 1992, and 1,157 between 1993 and 1996 (chi2(df = 2) = 680.9; P < 0.001). There was a marked increa...

[1] Salt release during sea ice formation in the Ross Sea coastal regions is regarded as a primary forcing for the regional generation of Antarctic Bottom Water. Passive microwave data from November 1978 through 2008 are used to examine the detailed seasonal and interannual characteristics of the sea ice cover of the Ross Sea and the adjacent Bellingshausen and Amundsen seas. For this period th...

OBJECTIVE To determine the overall cost effectiveness of surgical skills training on Robotic Surgical Simulator (RoSS). METHODS This study evaluates the cost analysis of utilizing RoSS for robot-assisted surgical training, at Roswell Park Center for Robotic Surgery. Trainees were queried for time spent on the RoSS console over a period of 1 year, starting from June 2010 to June 2011. Time spe...

Surface melt is an important process for the stability of ice shelves, and therewith Antarctic sheet. In Antarctica, absorption solar radiation mostly largest energy source surface melt, which further enhanced by snowmelt-albedo feedback (SMAF): Refrozen snow has a lower albedo than new snow, causes it to absorb more radiation, increasing available melt. This previously been shown increase appr...

BACKGROUND The Ross procedure and aortic homografts have both been shown to have superior hemodynamic performance after valve replacement, but there have been few comparisons. METHODS Sequential Doppler echocardiograms were performed up to 5 years after aortic valve replacement in 132 patients with the Ross procedure and 111 patients with an aortic homograft (AH). Measurements included assess...

OBJECTIVES The purpose of this study was to evaluate the long-term outcomes of the Ross procedure in a nationwide follow-up. METHODS This retrospective study involved all children treated with the Ross procedure in Finland between 1994 and 2009. The clinical records were reviewed for demographic and anatomical characteristics, Ross operation data, surgical history and status at the latest fol...
