1. Phosphorus utilization by sheep: effects of different levels on true absorption and fecal losses / Utilização de fósforo por ovinos: efeitos de diferentes concentrações na absorção real e perdas fecais
O objetivo do presente trabalho foi determinar a absorção real de fósforo (P), as perdas totais fecais e endógenas do mineral em ovinos alimentados com diferentes concentrações de P na dieta, através da determinação do P inorgânico e radioativo em amostras de sangue, fezes, urina, saliva e líquido do rúmen. Vinte e quatro ovinos machos, castrados

2. Effect of Time, Water Flow, and pH on Centripetal Passage of Radiophosphorus across Roots of Intact Plants 1
The effects of time, rate of the water flow, and ambient pH on centripetal passage of radiophosphorus across intact bean roots to the xylem were studied. Isotope which completed passage and entered the xylem stream, as well as amounts delivered to the plant top, served to measure centripetal passage.

8. Red cell life span after splenectomy in hereditary spherocytosis
Despite the persistence of spherocytosis after splenectomy in hereditary spherocytosis, it has usually been assumed that red cell life span returns completely to normal after this treatment. Diisopropyl fluorophosphate. DF32P, a noneluting red cell label, was given intravenously to 11 patients in five unrelated families 2-27 yr after splenectomy for typical

9. Role of Immunity in Viral-Induced Bacterial Superinfections of the Lung
Although viral illnesses are predisposing causes for pulmonary bacterial infections, the interrelationships of viral virulence and host immunity to alterations in susceptibility to bacterial infection are incompletely understood. We used two mutant strains of encephalomyocarditis virus (minimally virulent Mengo-37A and a highly virulent Columbia SK [Col-SK])

10. Quantitation of Semlike Forest virus RNAs in infected cells using 32-P equilibrium labelling.
In vitro cultured BHK and HeLa cells were labelled for several cell division cycles with 32-P-phosphate until they were equilibrated with radiophosphorus. After infection with Semliki forest virus (or mock-infection) these cells were analyzed for viral and ribosomal RNA by sucrose gradient centrifugation. From their radioactivities the mass of each RNA speci

11. Murine Resistance to Inhaled Neisseria meningitidis After Infection with an Encephalomyocarditis Virus
A reduction in pulmonary anti-bacterial activity due to a preceding viral illness has been suggested as the mechanism responsible for some meningococcal infections of the lung. We investigated this proposed pathogenesis by infecting mice with airborne encephalomyocarditis virus (EMC) and then challenging them 1, 4, and 7 days later with aerosols of Neisseria
