Methane emission is an important tool in the evaluation of manure management systems due to the potential impact it has on global climate change. Field procedures used for estimating methane emission rates require expensive equipment, are time consuming, and highly variable between farms. The purpose of this paper is to report a simple laboratory procedure for estimating methane emission from s...

This report was undertaken to draw together scientific findings on incinerator emissions and their impacts on human health. A broad range of health effects have been associated with living near to incinerators as well as with working at these installations. Such effects include cancer (among both children and adults) adverse impacts on the respiratory system, heart disease, immune system effect...

Introduction. Tuberculosis is a major cause of morbidity and mortality especially in high HIV burden settings. Active case finding is one strategy to potentially reduce TB disease burden. Xpert MTB/Rif has recently been recommended for diagnosis of TB. Methods. Pragmatic randomized trial to compare diagnosis rate and turnaround time for laboratory testing for Xpert MTB/Rif with TB microscopy an...

In October 2010, nine ministries and commissions of China jointly issued Guidance on the Strengthening of Dioxin Pollution Prevention [Ministry of Environmental Protection of People's Republic of China (MEP) 2010], which requires key dioxin-emitting industries to carry out comprehensive actions to reduce dioxin emissions. This is a major historical milestone in China's fight against dioxin poll...

To establish the chronology of the onset and evolution of the specialty that we now call surgical pathology, it is necessary to remember that the same term was used in Europe, beginning in the second half of the 19th century, to refer to the systematic teaching by university surgeons of the nature, diagnosis, and treatment of surgical dis­ eases (figs. 4-1, 4-2). There were clinical depart­ men...

Many hospitals deploy Medical Emergency (MET) and Cardiac Arrest teams to improve the management and treatment of patients who become critically ill. In many cases, blood results are key in allowing the clinicians involved in these teams to make definitive management decisions for these patients. Following anecdotal reports that these results were often delayed, we assessed the process of blood...

Organic gases undergoing conversion to form secondary organic aerosol (SOA) during atmospheric aging are largely unidentified, particularly in regions influenced by anthropogenic emissions. SOA dominates the atmospheric organic aerosol burden and this knowledge gap contributes to uncertainties in aerosol effects on climate and human health. Here we characterize primary and aged emissions from r...

Although William Heberden was one ofthe most distinguished clinicians ofhis day, no attempt has previously been made to bring together the available material, scattered in various published works and unpublished MSS, which could throw light on his London practice. I attempt in this article to find some answers to three groups of questions: first, what were the factors that Heberden had to weigh...

With unwarranted enthusiasm, the popular press has embraced hypoglycemia as an explanation for a host of physical ailments. Although this has permitted purveyors of numerous "treatments" to do a brisk business, very little helpful and accurate information has been communicated about hypoglycemia. Lynn Bennion, a Stanford-based clinician, has written a book that provides the general public acces...
