    摘要: Implantable compositions capable of providing release of bioactive agents according to a predetermined release profile and methods for their use. Such compositions include at least one ceramic substrate; a bioactive substance loaded on a surface of a said ceramic substrate forming a loaded surface zone operable to release said bioactive substance according to a release profile under physiological conditions; and a biodegradable polymer having an in vivo degradation period, forming a continuous or discontinuous coating on an area of a said ceramic substrate. The composition comprises at least two said loaded surface zones having different release profiles, or at least two said coatings having different in vivo degradation periods.

    摘要: A method for forming an acetabular shell includes providing a working surface such as a mandrel, and spraying the working surface with a first layer of material having a first composition such as aluminum oxide. After a suitable thickness is generated, the spray composition is gradually changed to other compositions having desired particle sizes and distribution. In one example, the composition is changed to a mixture of aluminum oxide and titanium oxide and/or titanium. As thickness builds up, the relative amount of aluminum oxide is decreased such that the composition is all titanium and titanium oxide. After a desired thickness is generated, the acetabular shell is extracted off the mandrel.

    摘要: This invention relates to an orally effective herbal extract-based composition having broad-spectrum anticancer activity, more specifically a method of treating, inhibiting and/or preventing malignant tumors of the colon, intestine, stomach, breast, melanoma, glioblastoma, lung, cervix, ovary, prostate, oral cavity, larynx, liver, pancreas, kidney, bladder, endothelial cells, leukemia and myeloma using a herbal extract of Zizyphus, rich in betulinic acid. An advantage of the extract is that the betulinic acid has low systemic toxicity. The extract inhibits Protein Kinase C activity of cancer cells and induces apoptosis.

    摘要: A flush and fill process is used to ready a fuel cell cooling circuit for initial use. An external flushing system relasably connected to the cooling circuit circulates flushing coolant through the cooling circuit to remove contaminants from the wetted surfaces of the cooling circuit before the fuel cell is put into use. The flushing system includes a pump for circulating the flushing coolant through the cooling circuit, filters for removing contaminants from the coolant and a heater for elevating the temperature of the coolant. Following the flushing process to remove contaminants, the flushing system is disconnected from the cooling circuit and the cooling circuit is filled with fresh coolant.
