摘要:
An airtrap for a medical or physiological fluid in one embodiment includes a conical housing having a radius that increases from its top to its bottom when the housing is positioned for operation; a medical or physiological fluid inlet located at an upper portion of the conical housing; a medical or physiological fluid outlet located at a lower portion of the conical housing, the inlet and the outlet positioned and arranged so that medical or physiological fluid spirals in an increasing arc around an inside of the conical housing downwardly from the inlet to the outlet; and a gas collection area located at an upper portion of the conical housing. In another embodiment, the airtrap is shaped like a seahorse having a head section and a tail section. Any of the airtraps herein may be used for example in blood sets, peritoneal dialysis cassette tubing, and drug delivery sets.

A range of carbon materials can be produced using lignin in combination with synthetic phenolic resins or naturally occurring lingo-cellulosic materials. The lignin, which is essentially a naturally occurring phenolic resin, has a carbon yield on pyrolysis similar to that of the synthetic resins, which aids processing. The lignin can be used as a binder phase for synthetic resin or lignocellulosic materials allowing the production of monolithic carbons from a wide range of precursors, as the primary structural material where the thermal processing is modified by the addition of small quantities of synthetic resin materials or as structure modified in the production of meso/macro porous carbons in either bead, granular or monolithic form. A carbonised monolith is provided comprising mesoporous and/or macroporous carbon particles dispersed in a matrix of microporous carbon particles with voids between the particles defining paths for fluid to flow into and through the structure. The monolith may take the form of a shaped body having walls defining a multiplicity of internal transport channels for fluid flow, the transport channels being directed along the extrusion direction. The monolith may be made by carbonising a shaped phenolic body based on phenolic resin precursors. In a method for producing such a carbonisable shaped resin body solid particles of a first phenolic resin are provided which is partially cured so that the particles are sinterable but do not melt on carbonisation. The particles of the first phenolic resin are mixed with particles of a second phenolic resin that has a greater degree of cure than said first phenolic resin and has a mesoporous and/or macroporous microstructure that is preserved on carbonisation. The resulting mixture is formed into a dough e.g. by mixing the resin particles with methyl cellulose, PEO and water, after which the dough is extruded to form a shaped product and stabilising in its shape by sintering.
摘要:
A system and method for the practice of apheresis employs modules in the system which can be selected for a particular patient to treat particular situations or combinations of difficulties. In one example, Gal-3 mediates a large number of body reactions, and is an effective protector of tumor microenvironments and the like, as well inflammation driver. Removal of Gal-3 may make antic-cancer treatments, like photopheresis and TNF administration more effective. Separate modules, such as one for photopheresis and one for TNF receptor removal, may be combined with a module for the reduction of Gal-3, to render the combination of treatments each more effective than if administered alone.

摘要:
A plasmapheresis device includes a column or other flow mechanism in which plasma flows following separation of the plasma from cellular components like blood cells, platelets and the like. The column includes a moiety, such as an antibody, which selectively binds to galectin-3. By removing galectin-3 from the blood stream of a mammal by at least 10%, improvements in the treatment of inflammation, suppression of the formation of fibroses, and a variety of cancer treatments can be effected or improved. The device provides for multiple columns to remove a variety of elements but includes one which selectively removes galectin-3 from the blood flow. Other agents may be added to the plasma before recombination with the cellular components of the blood, and before returning the recombined flow to the patient.

The present invention relates to a molecule binding to soluble tumor necrosis factor receptor (sTNFR) for use in a method for sensitizing a tumor cell in a patient to a treatment with a chemotherapeutic agent, wherein said molecule is immobilized on a solid support that is contacted with a body fluid of said patient. Furthermore, the present invention refers to a method for sensitizing a tumor cell and to a body fluid from which sTNFR has been removed for use in a method for sensitizing a tumor cell in a patient to a treatment with a chemotherapeutic agent. Moreover, the present invention refers to a chemotherapeutic agent for use in a method for treating a tumor in a patient for sensitizing a tumor cell of said tumor in said patient to a treatment with said chemotherapeutic agent.
摘要:
A system for ultrafiltration employs a crossflow filtration module for extracting a fraction from a sample fluid (e.g., blood) and a recirculating permeate loop to produce a concurrent permeate flow through the filtration module to maintain a positive transmembrane pressure at all points of the crossflow filter. Permeate in the recirculating loop is enriched by a processing module and stabilized by removing an enriched fraction thereof. In an embodiment, the enriched fraction is concentrated plasma that is returned to a patient.
