Murine Pulmonary Alveolar Macrophages: Rates of Bacterial Ingestion, Inactivation, and Destruction
Journal of Infectious Diseases, 1976The component processes of phagocytosis (ingestion, inactivation, and destruction of bacteria) were studied in mice by histological and microbiological techniques after aerosol infection with Staphylococcus aureus. Rates of bacterial ingestion and inactivation were (respectively): 0 hr, 37.7% and 0; 1 hr, 64.5% and 45.8%; 2 hr, 75.9% and 67.9%; 4 hr ...

The Role of Ingestion Rate in Optimal Foraging Strategies
BioScience, 1984The information explosion has made it impossible for biologists to keep abreast of research in specialties other than their own. To bring a sampling of the best of basic research in biology, BioScience publishes these expanded abstracts of research reports, deemed especially worthy of wide dissemination by the editors of AIBS member society journals ...

Human and Ecological Risk Assessment: An International Journal, 2014
ABSTRACTThere is a lack of scientifically justified approaches for assessing sediment ingestion rates of people exposed to contaminated sediments. Consequently, a method was developed to estimate sediment ingestion rates from: (1) hand-to-mouth contact with sediments and (2) incidental ingestion of surface water containing suspended sediments.

Estimating freshwater turtle mortality rates and population declines following hook ingestion
Conservation Biology, 2017Abstract Freshwater turtle populations are susceptible to declines following small increases in the mortality of adults, making it essential to identify and understand potential threats. Freshwater turtles ingest fish hooks associated with recreational angling, and this is likely a problem because hook ingestion is a source of ...

Relations between preconditioned rate of solution ingestion and rate of post-irradiation intake
Physiology & Behavior, 1969Abstract Three groups of 12 rats per group were tested daily for 90 days on a 2-bottle 30-min preference test in which one bottle contained water and the second bottle contained either 1.0 per cent, 0.50 per cent or 0.10 per cent saccharin solution. A classically conditioned aversion was induced by pairing the taste of saccharin with an exposure to ...

Ingestion of juniper foliage reduces metabolic rates in woodrat (Neotoma) herbivores
Zoology, 2003Ingestion of plant secondary compounds by herbivores is predicted to increase resting or basal metabolic rates. We tested this hypothesis with two species of woodrat herbivores, Neotoma stephensi and Neotoma albigula, consuming diets of juniper (Juniperus monosperma), which is rich in plant secondary compounds. In nature, N.

Soil ingestion rates for children under 3 years old in Taiwan
Journal of Exposure Science & Environmental Epidemiology, 2015Soil and dust ingestion rates by children are among the most critical exposure factors in determining risks to children from exposures to environmental contaminants in soil and dust. We believe this is the first published soil ingestion study for children in Taiwan using tracer element methodology.

Ingestible Pill for Heart Rate and Core Temperature Measurement in Cattle
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006The livestock industry is an integral part of the United States economy. The continued production of quality beef requires new and improved methods for long term monitoring of animal health. Additional benefits can be realized from this class of technology, such as the ability to identify the presence of disease early and thereby prevent its spread. An

Oxidation rates of orally ingested carbohydrates during prolonged exercise in men
Journal of Applied Physiology, 1993Six male volunteers exercised on a cycle ergometer at 65% of maximal work load for 120 min on six occasions while ingesting water (W) only, four doses of maltodextrin (M) [0.92, 1.85, 2.77, and 3.70 g/kg body wt (4, 8, 12, and 16% M, respectively)], and sucrose (S) [1.85 g/kg body wt (8% S)]. Drinks were given during warm-up (8 ml/kg body wt) and each

Effect of rate of ingestion of diet on hexosemonophosphate shunt activity
American Journal of Physiology-Legacy Content, 1959Young adult male rats either were allowed to eat ad libitum or were force-fed a high carbohydrate diet for 6–7 weeks; the latter animals were given amounts of diet that would "pair-gain" them against the former ones. At the end of the feeding period, the animals were killed and homogenates were made of hepatic and epididymal fat tissue or slices were ...
