OBJECTIVES New resin cement (NRC) has been developed as a root repairing material and the material is composed of organic resin matrix and inorganic powders. The aim of this study was to compare the rat subcutaneous tissue response to NRC and mineral trioxide aggregate (MTA) cement and to investigate the tissue toxicity of both materials. MATERIALS AND METHODS Sixty rats received two polyethy...

This paper explores the interrelationship of women and the National Research Council of Canada during the 1916-1991 period. Although women received 14% of the NRC fellowships and bursaries before 1931, they fared less well during and after the Depression. Based on information obtained from primary and secondary written sources as well as from interviews with both women and men employed by the N...

There has been renewed interest in assessing the pilot scheme for compiling natural resources capitalization (NRC). A growing body of evidence highlights good effects that policy NRC on construction ecological civilization. No known empirical research focused exploring relationships between and carbon emissions reduction. This paper employs as civilization to investigate whether implementation ...

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 ...

BACKGROUND An evaluation of exercise counseling practices among nephrologists in 2001 demonstrated few clinicians assessing patients' levels of physical activity (PA) and counseling to increase activity. Recent Kidney Disease Outcomes Quality Initiative (KDOQI) cardiovascular guidelines recommended that nephrologists counsel patients to increase PA. Our objective was to ascertain whether nephro...

In 2002, the U.S. Nuclear Regulatory Commission (NRC) revised its regulations governing the use of byproduct materials for medical purposes (10 CFR Part 35). These changes were the result of a detailed, 4-year examination of the issues surrounding the medical use program of the NRC and are stated in the latest revision to its medical policy statement, published in the Federal Register on August...

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...
