AIM To measure the sleeping metabolic rate (SMR) of healthy infants in the first year of life. METHODS The SMR was measured on 73 infants aged 1 to 12 months in a special nursery using indirect calorimetry. One hundred satisfactory observations were made. The room air and radiative temperatures, humidity, and amount of insulation were measured. Parents chose the clothing and bedding that they...

BACKGROUND Men with Klinefelter syndrome have one or more extra X chromosomes and have endocrine abnormalities. Case reports have led to suggestions that men with Klinefelter syndrome have elevated risks of several cancers, but published cohort studies have been relatively small. We conducted a nationwide cohort study to examine these risks. METHODS We followed a cohort of 3518 men who had be...

OBJECTIVES To investigate types of cancer caused by occupational exposure to vinyl chloride monomer (VCM) and the temporal mortality trends of these cancers in workers from polyvinyl chloride (PVC) manufacturing factories in Taiwan, with follow-up of the cohort extended by 15 years, from 1980 to 2007. Methods A retrospective cohort study of workers from six PVC factories in Taiwan was conducted...

A new theoretical relation that does not require the constant age-specific mortality ratio assumption is established between the standardized mortality ratio (SMR) and the life expectancy. A set of regression equations is developed from the theoretical relation to derive estimates of the future expectation of life from estimates of the SMR. Curves are presented showing the changes in life expec...

The timing of snowmelt runoff (SMR) for 84 rivers in the western United States is examined to understand the character of SMR variability and the climate processes that may be driving changes in SMR timing. Results indicate that the timing of SMR for many rivers in the western United States has shifted to earlier in the snowmelt season. This shift occurred as a step change during the mid-1980s ...

OBJECTIVES The aim of this study was to explore the possibility of the short-term modulation of the soleus H reflex through self-induced modulation of the sensory-motor rhythm (SMR) as measured by electroencephalography (EEG) at Cz. METHODS Sixteen healthy participants took part in one session of neuromodulation. Motor imagery and mental math were strategies for decreasing SMR, while neurofee...

BACKGROUND The authors conducted a retrospective cohort mortality study on police officers from 1950-2005. METHODS Standardized Mortality Ratio (SMR) analyses were conducted separately for white male (n=2761), black (n=286), and female (n=259) officers. RESULTS Mortality from all causes of death combined for white male officers was significantly higher than expected (SMR=1.20; 95% confidenc...

1,3-Butadiene, a major ingredient of synthetic rubber, has been shown to be carcinogenic in two animal species. To assess the possible human carcinogenicity of 1,3-butadiene, a critical review was undertaken of the epidemiologic literature. An early retrospective study of 8017 males employed in tire manufacturing found excess mortality for lymphatic and hematopoietic neoplasms in production wor...

We study the problem of finding supermaximal repeats in large DNA sequences. For this, we propose an algorithm called SMR which uses an auxiliary index structure (POL), which is derived from and replaces the suffix tree index STTD64 [1]. The results of our numerous experiments using the 24 human chromosomes data indicate that SMR outperforms the solution provided as part of the Vmatch [2] softw...
