THERE is a wealth of information available on alternative feeding programs for broilers, layers and turkeys, the basis of which has always been the various National Research Council (NRC) publications. The most recent such publication is Nutrient Requirements of Poultry, Ninth Revised Edition, released in 1994, and so unfortunately this information is now 17 years old, which is a considerable t...

The purpose of this notice is to provide the public an opportunity to review a draft ISG, FCSS–ISG–10, Revision 2, which provides guidance to NRC staff to determine whether the minimum margin of subcriticality is sufficient to provide an adequate assurance of subcriticality for safety to demonstrate compliance with the performance requirements of 10 CFR 70.61(d). Additionally, listing of commen...

Extending relational algebra and rela-tional calculus with set-valued attributes and aggregate functions, ACM Transac-a tuple t in I, produces the output of the query on I ? ftg. Then both proofs in 9] show how to use this assumption to produce an expression in rst-order logic plus g that computes the transitive closure of a chain. Since the construction of 9] does not assume any auxiliary data...

In the previous issue of CBE (Vol. 1, Winter 2002), Bruce Alberts, president of the National Academy of Sciences, provided readers with an overview of some of our many initiatives in education (pp. 109–110). Much of that article focused on the work within the Center for Education of the National Research Council (NRC).1 That issue also contains an article by ASCB member William Wood (pp. 123–12...

MicroRNAs (miRNAs), non-coding RNAs regulating gene expression, are frequently aberrantly expressed in human cancers. Next-generation deep sequencing technology enables genome-wide expression profiling of known miRNAs and discovery of novel miRNAs at unprecedented quantitative and qualitative accuracy. Deep sequencing was performed on 11 fresh frozen clear cell renal cell carcinoma (ccRCC) and ...

The present study was conducted to investigate the effects of dietary lysine (Lys) and sex on growing quail performance and immunity parameters. The six dietary Lys: 10, 11.5, 13.0 (NRC 1994 recommendation), 14.5, 16.0 and 17.5 gr/kg were provided. The other essential amino acids except lysine were provided to meet or exceed NRC 1994 recommendation for growing quail. This experiment was carried...

Based on applications of the 1996 National Research Council (NRC) Nutrient Requirement of Beef Cattle (2000 update) model at our laboratories and on use of the model to evaluate published literature, it is our assessment that the NRC model (Level 1) represents an advancement in nutrient requirements of grazing cattle. We evaluated 8 published studies (35 treatment observations) to compare obser...

High visibility efforts in toxicity testing and computational toxicology including the recent National Research Council of the National Academies (NRC) report, Toxicity Testing in the 21st Century: A Vision and Strategy (NRC, 2007a), raise important research questions and opportunities for the field of exposure science. The authors of the National Academies report (NRC, 2007a) emphasize that po...
