This study was conducted to evaluate the use of Met and Lys levels in excess of NRC (1994) recommendations adapted to feeding periods more consistent with current industry applications. Diets were formulated to provide a minimum of 110% of NRC recommended levels for amino acids other than Met and Lys. Aliquots of the diets were fortified with DL-methionine and Lysine HCl to provide three levels...

The NRC is issuing this regulatory issue summary (RIS) to inform recipients of the status of the agency’s efforts to implement the requirements of Section 651(e) of the Energy Policy Act of 2005 (EPAct) on “Treatment of Accelerator-Produced and Other Radioactive Material as Byproduct Material.” This RIS updates the information contained in RIS 2007-22, “Status Update for Implementation of NRC R...

Proteomic experiments have produced a draft profile of the overall molecular composition of the mammalian neuronal synapse. It appears that synapses have over 1000 protein components and the mapping of their interactions, organization and functions will lead to a global view of the role of synapses in physiology and disease. A major functional subcomponent of the synaptic machinery is a multipr...

The growth and survival of children was studied after rehabilitation for malnutrition at the Nutrition Rehabilitation Centre (NRC) of St Mary's Hospital on average 1.5 year after discharge. The findings are intended partly to provide descriptive information on later progress in the community of these children and also to identify specific risk factors. Of 50 children eligible for follow-up, 39 ...

Highly polarized cells such as photoreceptors require precise and efficient strategies for establishing and maintaining the proper subcellular distribution of proteins. The signals and molecular machinery that regulate trafficking and sorting of synaptic proteins within cone inner segments is mostly unknown. In this study, we show that the polyphosphoinositide phosphatase Synaptojanin 1 (SynJ1)...

BACKGROUND The genome of the halophilic archaeon Halobacterium salinarum NRC-1 encodes for homologs of MutS and MutL, which are key proteins of a DNA mismatch repair pathway conserved in Bacteria and Eukarya. Mismatch repair is essential for retaining the fidelity of genetic information and defects in this pathway result in the deleterious accumulation of mutations and in hereditary diseases in...

This study was conducted to evaluate the carcass yield, abdominal fat deposition and chemical compositions of thigh and breast muscles of male Arian broilers fed three different lysine levels of 1) high lysine (110% NRC), 2) standard level suggested by National Research Council (NRC) and 3) low lysine (90% NRC) based on two expression ways of amino acid contents of feedstuffs, as total amino ac...

Introduction: The Martian north polar residual cap (NRC) lies on top of the north polar layered deposits (NPLD). The NRC is about 1m thick and composed primarily of large-grained, dust-poor water ice [1]. The mass balance of the north polar cap is uncertain. Satellite imagery reveals small reversible changes in its extent on an interannual basis [2]. Images with a pixel scale of up to 0.25 m/pi...

Interannual variation of forage quantity and quality driven by precipitation events influence beef livestock production systems within the Southern and Northern Plains and Pacific West, which combined represent 60% (approximately 17.5 million) of the total beef cows in the United States. The beef cattle requirements published by the NRC are an important tool and excellent resource for both prof...
