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 stabilized pharmaceutical composition of anticancer drug and a solvent like Polyethoxylated castor oil (cremophor) also containing any other suitable solubilizer suitable for human administration like dehydrated alcohol, is disclosed. Compositions prepared using this purified polyethoxylated castor oil enhance the stability of paclitaxel in such compositions.
摘要:
An effective prophylactic mucosal gene expression vaccine (GXV), made up of a cocktail of at least 4 different plasmid DNAs encoding corresponding RSV antigens, coacervated with chitosan to formulate nanospheres. In a murine model of RSV infection, intranasal administration with GXV results in significant induction of RSV-specific antibodies, nasal IgA antibodies, cytotoxic T lymphocytes, and IFN-γ production in the lung and splenocytes. A single dose of GXV induces a drastic reduction of viral titers.
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.
摘要:
According to one general aspect, a method may include replicating, to a software-as-a-service application, a plurality of pieces of master data from a physically remote master database. The method may also include converting the plurality of pieces of master data into one or more pieces of local data of the software-as-a-service application. The method may include changing one or more of either the pieces of master data or the pieces of local data. The method may further include synchronizing the changed pieces of either master data or local data between the remote master database and the software-as-a-service application.
摘要:
A knee joint prosthesis can include a tibial component that can have a tibial tray. The tibial tray can include a platform-like tray that defines a superior surface and an inferior surface. The platform-like tray can have a tray perimeter and a raised wall formed on the inferior surface. The raised wall can be offset inboard relative to the tray perimeter. Porous material can be disposed on the inferior surface of the platform-like tray at a location generally between the raised wall and the tray perimeter.
摘要:
An air conditioning system for a start-stop vehicle employs a compressor with a variable displacement. A controller determines a normal Climate Thermal Load (CTL) value for controlling a variable stroke of the variable displacement compressor. A stop event is detected in response to a speed of the vehicle and the occurrence of a predetermined deceleration. During the stop event, the variable stroke is increased by an amount determined in response to the normal CTL value, the speed of the vehicle, and a measure of the deceleration of the vehicle so that an evaporator temperature within the air conditioning system is allowed to decrease while the vehicle is stopping so that climate comfort can be maintained even while the engine is shut off during the subsequent time that the vehicle is stopped.
