Although increased mortality from diseases of the circulatory system has been observed in patients treated with radiotherapy, the effects of chronic low-dose radiation exposure are not clear. Among 90,284 US radiologic technologists who responded to a mailed questionnaire during 1983-1989, the authors evaluated mortality from circulatory system diseases through 1997 in relation to job history a...

> Abstract The circulatory system is one of the major organ systems in Malacostraca. As no consensus on malacostracan phylogeny exists it becomes necessary to evaluate different phylogenetic hypotheses for their impact on circulatory system evolution. Four prevailing hypotheses were therefore used to map different circulatory system characters. The comparison shows that the length of the heart,...

INTRODUCTION The West Bank in the Palestinian Territories is undergoing an epidemiologic transition. We provide a general description of mortality from all causes, focusing on chronic disease mortality in adults. METHODS Mortality data analyzed for our study were obtained from the Palestinian Ministry of Health in the West Bank for 1999 through 2003. Individual information was obtained from d...
