摘要:
Cells that are in the process division are vulnerable to damage by AC electric fields that have specific frequency and field strength characteristics. The selective disruption of rapidly dividing cells can therefore be accomplished by imposing an AC electric field in a target region for extended periods of time. Some of the cells that divide while the field is applied will be damaged, but the cells that do not divide will not be harmed. This selectively damages or disrupts rapidly dividing cells like parasites, but does not harm normal cells that are not dividing.

A method of conjugating a carboxylate-containing molecule to an amine-containing macromolecule to form a substituted macromolecule is provided. The method includes (a) forming a first solution by dissolving a substance comprising at least one macromolecule having free amine groups in an aqueous basic solution; (b) forming a second solution by combining at least one carboxylate-containing molecule with at least one acid acceptor in an aprotic solvent; (c) adding at least one carboxylate activating agent to the second solution to form an activated carboxylate-containing molecule; (d) combining the first solution and second solutions to form a multiphasic solution; and (e) isolating the resultant substituted macromolecule from the mixture. A substituted macromolecule produced by the aforementioned method is also provided. Further provided is a method of enhancing a magnetic resonance image of a subject including administering the carboxylate-containing molecule-substituted macromolecule produced by the aforementioned method.
摘要:
A tissue culture system for production of infectious hepatitis C virus is described. In particular, the invention provides recombinant monocistronic and bicistronic genomic constructs for production of virus, including constructs for production of wild-type HCV type 2a strain JFH1 and constructs for production of chimeric viruses comprising HCV proteins from strain JFH1 and a second HCV isolate. Constructs of the invention also include a reporter gene to facilitate measurement of RNA replication and viral infectivity in cultures. The cell culture system may also include various factors that improve viral replication or infectivity. In addition, a neutralization assay using HCV grown in cell culture is described.

摘要:
A double-sidedly self-adhesive planar element which is intrinsically heatable in a self-regulating way and at the same time has a particularly high flexibility. The planar element has a layer sequence of a posistor heating layer, a contacting layer and an adhesive layer, the contacting layer being a two-dimensional perforate contacting element which within the planar element is therefore present as a contacting element which has not been applied to a backing. Also disclosed is an adhesively bonded assembly of a bonding substrate and a planar element of the aforesaid kind, a method of producing a planar element of the aforesaid kind, and a method of using a planar element of the aforesaid kind for heating an adhesively bonded assembly.
摘要:
Disclosed herein are isolated nucleic acids, compositions of isolated nucleic acids, and compositions of polypeptides that are useful for the generation, enhancement, or improvement of an immune response to a target antigen. Some embodiments of the compositions include hepatitis B core antigen (HBcAg) protein and a heterologous protein antigen. In some embodiments, an isolated nucleic acid encoding hepatitis B core antigen (HBcAg) protein and a heterologous protein antigen is disclosed. Also disclosed herein are methods of administering the composition or isolated nucleic acid to generate an immune response, where HBcAg acts as adjuvant to improve the immune response to the heterologous protein. In certain embodiments, the HBcAg is as a stork or heron hepatitis antigen.
摘要:
Enhancing the effectiveness of therapeutic ionizing radiation and other treatments of disease in which cells are to be destroyed or modified, by subjecting cells in need thereof to low-dose radiation to increase the sensitivity of the cells to subsequent subjection with a lethal dose of high dose radiation (HDR), a chemotherapeutic agent, or other type of therapeutic treatment.
摘要:
In one example, a system electrically stimulates target cells of a living animal using an elongated structure, a modulation circuit and a light pathway such as provided by an optical fiber arrangement. The elongated structure is for insertion into a narrow passageway in the animal such that an end of the elongated structure is sufficiently near the target cells to deliver stimulation thereto. The modulation circuit is for modulating the target cells while the elongated structure is in the narrow passageway, where the modulation circuit is adapted to deliver viral vectors through the elongated structure for expressing light responsive proteins in the target cells. The light pathway is used for stimulating the target cells by delivering light to the light-responsive proteins in the target cells.

Embodiments include nucleic acids encoding the chimeric NS3/4A polypeptides, the encoded polypeptides, compositions containing said nucleic acids, compositions containing said chimeric polypeptides, as well as methods of making and using the aforementioned compositions including, but not limited to medicaments and vaccines.
摘要:
Present invention provides a method for treating cancer which comprises co-administration of an angiogenic agent to enhance the vascular supply within tumors, particularly tumors capable of maintaining their viability under hypoxic conditions, and a anticancer therapy (e.g. chemotherapy and radiation therapy) to which the cancer is susceptible. Induction of angiogenesis increases the delivery of anticancer agents to the hypoxic tumor cells within the tumors, and as a result, improves the effectiveness of the anticancer therapy in eliminating or reducing cancers. The present invention also includes formulations comprising of lysine(L- and/or D-isomers as well as, or, their “activated” version either in isolation or in various combinations, as described, along with additive(s) and one or more chemotherapeutic agent(s) and/or radio-sensitizing agent(s).
