Potent anti-adherent activity was detected in fermentation extracts of microbial strain FO-5050. Active compounds designated macrosphelide A and B were isolated and the structure was determined to be 16-membered macrolide antibiotics possessing three ester bonds in the ring structure. Macrosphelide A dose-dependently inhibited the adhesion of HL-60 cells to LPS-activated HUVEC monolayer (IC50, ...
Brain blood flow increases during the first week of living at high altitude. We do not understand completely what causes the increase or how the factors that regulate brain blood flow are affected by the high-altitude environment. Our results show that the balance of oxygen (O(2)) and carbon dioxide (CO(2)) pressures in arterial blood explains 40% of the change in brain blood flow upon arrival ...
In the QBIC (Query By Image Content) project we are studying methods to query large on-line image databases using the images' content as the basis of the queries. Examples of the content we use include color, texture, and shape of image objects and regions. Potential applications include medical ("Give me other images that contain a tumor with a texture like this one"), photo-journalism ("Give ...
The rapid-release mechanisms of standard extract from Ginkgo biloba leaf (EGb) in the polyethylene glycol (PEG) 6000 dispersions were investigated. The apparent equilibrium solubilities of the total flavone glycosides and the soluble solid materials of EGb increased linearly with the increasing concentrations of PEG 6000 solutions. In DSC curves, the peak, onset and endset temperatures of solid...
