摘要:
The present invention includes compositions and methods for the preparation and delivery of calcium citrate under physiological conditions by preparing solid preformed calcium citrate, adding citric acid to the calcium citrate, wherein citric acid is added to the calcium citrate in a molar ratio of between 0.1 and 0.6 mol of citric acid per mol of calcium citrate to provide a calcium citrate-citric acid mixture; and forming a tablet from the calcium citrate-citric acid mixture. The compositions and methods were found to increase the solubility of iron and calcium.
摘要:
This invention provides liposomes containing one or more N-acylated phosphatidylethanolamines, such liposomes being useful for localizing the delivery of bioactive agents to cells.
摘要:
Peptide-lipid conjugates are incorporated into liposomes so as to selectively destabilize the liposomes in the vicinity of target peptidase-secreting cells, and hence, to deliver the liposomes to the vicinity of the target cells, or directly into the cells. The liposomes can thus be used to treat mammals for diseases, disorders or conditions, e.g., tumors, microbial infection and inflammations, characterized by the occurrence of peptidase-secreting cells.
摘要:
The present invention is an apparatus, method and system for determining the coefficient of elasticity of a target by detecting determining simultaneously two or more critical-angle reflections of an ultrasound wave from the target using an ultrasound transducer that includes a transmitter and two or more receivers and calculating the elasticity coefficients of the target.

摘要:
An apparatus for connecting a windscreen and a canopy to an aircraft is provided that includes a first frame for securing to the windscreen and a second frame for securing to the canopy. At least one movable joint connects the first frame to the second frame. The at least one movable joint deforms in response to an object striking at least one of the windscreen and the canopy to allow for relative movement between the first and second frames.
