Abstract:
Methods are described that bias cells, such as potent and multipotent stem cells, by transfection with a nucleic acid sequence, to differentiate to a desired end-stage cell or a cell having characteristics of a desired end-stage cell. In particular embodiments, human neural stem cells are transfected with vectors comprising genes in the homeobox family of transcription factor developmental control genes, and this results in a greater percentage of resultant transformed cells, or their progeny, differentiating into a desired end-stage cell or a cell having characteristics of a desired end-stage cell.
Abstract:
Described herein are methods and compositions for expressing an antibody or a fragment thereof in a microorganism and use of the microorganism to treat or prevent a pathogenic infection in a mammal.
Abstract:
The invention provides a method of up-regulating genes in cultured human bone marrow mesenchymal stem cells, the method comprising culturing the stem cells in a nutrient medium together with cells from a limb of a limb-regenerating animal. In the method, the limb-regenerating animal is preferably a species of the family Polychrotidae. Another method of the invention provides for up-regulating genes maintaining pluripotency and proliferation in cultured human bone marrow mesenchymal stem cells by culturing the stem cells in a nutrient medium together with mouse embryonic stem cells.
Abstract:
Disclosed herein are new immunotherapy methods that involve the isolation of cancer stem cells from tumor tissue and use of the cells either directly or indirectly through proteins or other factors associated with the cells to activate antigen presenting cells. The activated antigen presenting cells are useful as a therapy against the tumor. Also disclosed herein are novel methods of isolating and characterizing cancer stem cells and producing individual cancer stem cell lines. Dendritic cell lines are also disclosed herein.
Abstract:
This invention relates to components useful for medical articles, such as a syringe assembly, having sliding surface(s) coated with a composition including organopolysiloxane(s), the coating being adhered to the surface(s) of the component by crosslinking induced by oxidative treatment and irradiation with an isotope, electron beam or ultraviolet radiation or heat treatment; medical articles including the same; methods to reduce static and kinetic friction between slidable surfaces; and articles of low friction prepared thereby.
Abstract:
A procedure to machine openings in work pieces which provides two cutting blades (11, 12), defining a cutting blade axis, adjacent to a work piece in which an opening is to be machined, the opening defining a distance between two oppositely positioned opening edges and defining an opening axis. The opening axis and the cutting blade axis are inclined at an acute angle (&agr;) to one another in a way that the distance between the cutting blades parallel to the opening axis (9) is equal to the required distance between the opening edges. With the increasing wear of the cutting blades, the inclination angle is reduced so that the cutting blade distance parallel to the opening axis continues to correspond to the required distance of the opening edges.
Abstract:
Disclosed herein are methods for producing a stem cell bank and providing stem cell samples for purchase or use. Also, provided herein are embodiments relating to a stem cell bank and stem cell banking system.
Abstract:
Disclosed herein are methods and materials for producing a more developmentally potent cell from a less developmentally potent cell. Specifically exemplified herein are methods that comprise introducing an expressible dedifferentiating polynucleotide sequence into a less developmentally potent cell, wherein the transfected less developmentally potent cell becomes a more developmentally potent cell capable of differentiating to a less developmentally potent cell of its lineage of origin or a different lineage.
Abstract:
An improved seating apparatus for an aircraft includes a seat assembly and a quick install track fitting assembly for securing the seat assembly to the aircraft. In a preferred embodiment, the quick install track fitting assembly is made up of a track fitting body for insertion into an aircraft seat track and a manual lever that is pivotably attached to the track fitting body. The manual lever has a lever release position and a lever lock position. A force bearing plunger is movably attached to the manual lever for transferring force to the aircraft seat track. The force bearing plunger has a track release position and a track lock position, wherein both positions correspond to the lever release and lever lock positions of the manual lever. A lock may also be provided for maintaining the plunger in the track lock position when the manual lever is in the lever lock position. The quick install aircraft track fitting may further include a spring loaded secondary plunger to help locate and provide a secondary lock for securing the seat assembly into a proper position within the aircraft seat track. Moreover, the quick install track fitting may further include an anti-rattle feature that urges the force bearing plunger against the top of the seat track.
