This study evaluated whether the African cyprinid Barbus neumayeri from Rwembaita Swamp (low-oxygen) and Njuguta River (high-oxygen) in the Kibale National Park, Uganda differed in traits related to aerobic and anaerobic metabolic potential. Haematocrit was measured as an index of blood oxygen-carrying capacity, and tissue activities and isozyme composition of lactate dehydrogenase (LDH) were m...
Electronic data reporting from public health laboratories to a central site provides a mechanism for public health officials to rapidly identify problems and take action to prevent further spread of disease. However, implementation of reference laboratory systems is much more complex than simply adopting new technology, especially in international settings. We describe three major areas to be c...

The Pneumonia Etiology Research for Child Health study was conducted across 7 diverse research sites and relied on standardized clinical and laboratory methods for the accurate and meaningful interpretation of pneumonia etiology data. Blood, respiratory specimens, and urine were collected from children aged 1-59 months hospitalized with severe or very severe pneumonia and community controls of ...

Several nature-like fishway designs have been constructed in the northeastern US, but none of these fishways have been quantitatively evaluated for passage of northeastern diadromous species. This report summarizes data on passage performance from two studies of nature-like fishway designs for passage of river herring in the field (Town Brook, Plymouth, Massachusetts, and East River, Guilford, ...
A precursor laboratory, the Automated Astrophysical Site Testing Observatory (AASTO) has been collecting atmospheric data relevant to astronomy from the US Amundsen-Scott South Pole station for the last decade.1,2 The AASTINO (Automated Astrophysical Site Testing INternational Observatory) represents the next step in a program to develop fully automated site testing laboratories, capable of bei...
Elimination of medical errors is important for pathologists. Errors occurring in surgical pathology involve specimen defects, specimen labeling, processing, diagnosis, and reporting defects. Errors occur during prelaboratory, laboratory, and postlaboratory phases. We reviewed our experience with mislabeled specimens in the laboratory for an 18-month period. The percentage of error was calculate...
This study investigated the effects of prospective-user factors and five cognitive sign features on guessability of safety signs. Sixty Hong Kong Chinese subjects guessed the meanings and rated the sign features of 63 Mainland China safety signs. The prospective-user factors of working or site visit experience at laboratory or construction site, awareness of safety signs in daily life, injury e...
The reproductive behaviors of two species of fruit fly, Drosophila melanogaster and D. nigrospiracula, were compared in field and laboratory populations. A number of differences were observed in the behavior of the two species in their natural habitats. D. melanogaster, which was observed on citrus, mates at its feeding site, whereas D. nigrospiracula, which is cactiphilic, mates on a non-resou...
