Bulk shear viscosities of endogenous and exogenous lung surfactants.
Bulk shear viscosities were measured with a cone and plate microviscometer as a function of concentration, shear rate, and temperature for lavaged calf lung surfactant (LS), Exosurf, Infasurf, Survanta, and synthetic lipid mixtures dispersed in normal saline. Viscosity increased with phospholipid concentration for all surfactants, but its magnitude and shear dependence varied widely among the d...

As nanotechnology-based products enter into widespread use, nanomaterials will end up in disposal waste streams that are ultimately discharged to the environment. One possible end-of-life scenario is incineration. This review attempts to ascertain the potential pathways by which nanomaterials may enter incinerator waste streams and the fate of these nanomaterials during the incineration process...

To further elucidate the migration history of the brown bears (Ursus arctos) on Hokkaido Island, Japan, we analyzed the complete mitochondrial DNA (mtDNA) sequences of 35 brown bears from Hokkaido, the southern Kuril Islands (Etorofu and Kunashiri), Sakhalin Island, and the Eurasian Continent (continental Russia, Bulgaria, and Tibet), and those of four polar bears. Based on these sequences, we ...
متن کاملPharmacokinetics of cefpiramide (SM-1652) in humans.
The pharmacokinetics of cefpiramide (SM-1652) were studied after the intravenous administration of single or multiple doses to 21 healthy volunteers. The cefpiramide concentration in plasma at time zero after a bolus intravenous injection of 500 or 1,000 mg was 152 or 303 micrograms/ml, respectively. The maximum cefpiramide level in plasma at the end of a 1-h infusion of 1,000 or 2,000 mg was 1...
متن کاملLocalisation of exogenous surfactants in cell membranes in the air-blood barrier: rat model.
The use of exogenous surfactants has been introduced into the therapy of patients of different ages. Much better results have been obtained in the treatment of respiratory distress syndrome with surfactants enriched with surfactant proteins. In the following study we used protein-containing surfactants (survanta and curosurf). The aim of the following study was to determine the localisation of ...
