摘要:
Concentrates or proliposomal compositions of poorly water-soluble drugs and compounds, comprising of one or more membrane forming lipids, a membrane stabilizing agent, in a suitable vehicle, and optionally containing a Polyethylene Glycol (PEG)-coupled phospholipid or a mixture thereof and further, optionally containing pharmaceutically acceptable excipients such as antioxidants, buffering agents, acidifying agents etc. are provided, which have superior long term stability. The concentrates of proliposomal compositions instantly form liposomes of the said poorly water-soluble drugs and compounds on rapid injection to a diluting fluid, the liposomal composition so obtained, characterized by a physical stability more than 24 hours, ≧95% drug encapsulation and having a particle size diameter of less than 100 nm. The liposomal compositions so obtained can further be directly administered to patients in need of treatment of the poorly water-soluble drugs and compounds.

A process for making a sintered ceramic medical device, comprising providing an unsintered ceramic composition, forming the unsintered ceramic composition into a green body that comprises unsintered ceramic, irradiating the green body with microwave radiation, and cooling the sintered body. The microwave radiation has a frequency capable of heating the unsintered ceramic to a temperature sufficient to sinter the green body, thereby preparing a sintered ceramic medical device. A medical device comprising volumetrically sintered ceramic, and a volumetrically sintered ceramic are also disclosed.
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.

A stable pharmaceutical composition comprising a solution of disodium pamidronate in an aqueous solvent and a process for the preparation thereof. The solution of disodium pamidronate is free of particulate matter and has an alkaline pH. The process for preparation of the stable pharmaceutical composition comprises adding disodium pamidronate and optionally a sugar into an aqueous solvent; heating the said mixture at a temperature in the range of 50° C. to 90° C. to obtain a clear solution. It is cooled to ambient temperature, filtered, filled and stored in a conventional and untreated glass container and sealed with normal elastomeric closure. The sealed container is sterilized by steam sterilization.

A method of blocking RSV-ICAM-1 interaction by administering an effective amount of agents for blocking ICAM sites of binding is provided. Also provided is a compound for blocking RSV-ICAM-1 interaction including an agent for blocking ICAM sites of binding.
摘要:
A novel pump pressure limiting method for preventing coolant in a cooling system from reaching pressures that exceed predetermined system coolant pressure limits. The method includes reducing the system coolant pressure, as needed to prevent system over-pressurization, by reducing the operational speed of a coolant pump used to pump the coolant through the system. In one embodiment, the system coolant pressure is determined directly, by measurement of the pressure of the coolant in the system typically using pressure sensors. The operational speed of the coolant pump is then reduced until the system coolant pressure decreases to within the predetermined pressure limits. In another embodiment, the system pressure is determined indirectly, by obtaining pressure-indicating data such as coolant temperature. The coolant system pressure is then correlated with the coolant temperature or other data and then the operational speed of the coolant pump is reduced accordingly.

摘要:
A valve extension handle is disclosed in the present invention. Said valve extension handle is comprised of a extension member with opposed first and second ends, a clamping member connected to the first end of the extension member, and a control member connected to the second end of the extension member. Said clamping member can be attached to the gas tank valve. When the control member connected to the second end of the extension member is turned, the clamping member attached to gas tank valve moves gas tank valve to turn on or shut off the gas flow from said tank.
