In this study we examined rates of readmission and predictors of readmission among patients leaving hospital AMA. METHODS We prospectively studied 97 consecutive patients who left the general medicine service of an urban teaching(More)
Data on the emissions of oxides of nitrogen from the soil during the early part of the wet season are reported for nutrient-rich and nutrient-poor sandy soils at Nylsvley, South Africa. The emissions of NOx and N2O following the first wetting event of the season are elevated relative to subsequent events. The observed high emission rates (76 ng N-NO m-2(More)
Epidemiologic studies have suggested that dietary intake and blood levels of folate may be inversely related to the risk of breast cancer. However, epidemiologic evidence has not been consistent nor has it provided unequivocal support for this purported inverse relationship. Recent evidence has also raised a concern that folate supplementation may promote(More)
Epidemiologic studies have suggested that dietary folate intake is inversely related to breast cancer risk. However, epidemiologic evidence has not been consistent nor has it provided unequivocal support for this purported inverse relationship. This study investigated the effect of dietary folate on N-methyl-N-nitrosourea (MNU)-induced mammary tumorigenesis(More)
Folate supplementation may reduce the risk of colorectal dysplasia and cancer in subjects with chronic ulcerative colitis (UC). The interleukin (IL) 2- and beta(2)-microglobulin (beta(2)m)-deficient (IL-2(null) x beta(2)m(null)) mice spontaneously develop colon cancer in the setting of chronic UC. This study investigated the effects of dietary folate on the(More)
BACKGROUND Rooming houses are an important source of housing for low-income Canadians.

METHODS Interviews were conducted with a representative sample of 295 residents in 171 rooming houses in Toronto. Health status was assessed(More)
Heart rate (HR) responses evoked by 1 sec of 85-dB white noise were studied in 12 1-year-old pigtailed macaques, 6 of which were raised in social isolation and 6 with mothers and peers. Tests were given for 5 days, with 25 trials each day. Although baseline HR did not differ between groups, the pattern of change from baseline was not the same. Isolates(More)
