Ross River virus is a common mosquito-borne arbovirus responsible for outbreaks of polyarthritic disease throughout Australia. To better understand climatic factors preceding outbreaks, we compared seasonal and monthly rainfall and temperature trends in outbreak and nonoutbreak years at four epidemic-prone locations. Our analyses showed that rainfall in outbreak years tended to be above average...

BACKGROUND It is suggested that in young adults the Ross procedure results in better late patient survival compared with mechanical prosthesis implantation. We performed a propensity score-matched study that assessed late survival in young adult patients after a Ross procedure versus that after mechanical aortic valve replacement with optimal self-management anticoagulation therapy. METHODS A...

BACKGROUND The Ross procedure has become an accepted and sometimes preferred alternative to mechanical aortic valve replacement. One criticism of the Ross procedure is that it may have a higher operative mortality, morbidity, and cost. Several groups have shown that this operation can be performed safely with less than 3% mortality. The issue of higher cost has not been resolved. In this retros...

A progressive selection for broiler live and processing performance traits has changed broiler growth patterns during the post hatch period. However, limited information is available to understand whether changes have also occurred during the embryonic stages. This study aims to examine influences of broiler strain on nutrient availability, embryonic development, and nutrient metabolism during ...

There is little research data available on the digestible Lys requirement of broilers from 2 to 4 wk of age. Two experiments were conducted to determine the digestible Lys requirements of male and female Ross x Ross TP16 broilers from 14 to 28 d. Two diets (dilution and summit) consisting of corn, soybean meal, poultry by-product meal, and peanut meal were formulated to be adequate in all other...

Broiler performance is known to be related to embryonic developmental parameters. However, strain or genotype differences with regard to embryo physiological parameters and juvenile growth have received little attention. A total of 1,200 hatching eggs produced by Cobb and Ross broiler breeders of the same age were studied. At setting for incubation and between 66 and 130 h of incubation, egg re...

ROSS |7] is an object-oriented language developed for building knowledge-based simulations [4l. SWIRL |5, 6] is a program written in ROSS that embeds knowledge about defensive and offensive air battle strategies. Given an initial configuration of military forces, SWIRL simulates the resulting air battle. We have implemented ROSS and SWIRL in several different Lisp environments. We report upon t...

BACKGROUND There are several options available for aortic valve replacement (AVR), with few comparative reports in the literature. The optimal choice for AVR in each age group is not clear. OBJECTIVES The study sought to report and compare outcomes after AVR in the young using data from a national database. METHODS AVR procedures were compared after advanced matching, both in pairs and in a...
