Abstract:
A non-human chimeric animal useful as a model for human HV infection, comprising a mammal M5 having xenogeneic cells; mammal M5 being derived from a mammal M1 treated to substantially destroy its hematopoietic cells and then transplanted with hematopoietic cells derived from one or more mammals M2 and transplanted with liver tissue from a mammal M3, the one or more mammals M2 and mammal M3 being from the same or from a different species; the transplanted hematopoietic cells from the one or more mammals M2 being either one or both of a hematopoietic cell preparation from a T cell deficient mammal or of a T cell depleted mammalian stem cell or bone marrow preparation; the transplanted liver tissue from mammal M3 being either a human liver tissue preparation or a liver tissue preparation from a non-human mammal capable of being infected by HV; the liver tissue preparation in the M5 mammal being infected by HV.
Abstract:
Des analogues RXD non peptidiques inhibent des interactions moléculaires et cellulaires biologiques qui dépendent de la reconnaissance de RXD, X représentant l'un des restes d'amino acides G, E, Y, A ou F. En particulier les succédanés RGD n'ont pas de séquences d'amino acides alpha-naturels et comprennent un groupe guanidino et un groupe terminal carboxyle espacés par une chaîne de 11 atomes, dont au moins 5 sont des atomes de carbone. Les composés empêchent l'adhésion des cellules et sont utiles pour le traitement de divers états pathologiques, par exemple, la thrombose, les maladies autoimmunes, les métastases, les allergies, les réactions hôtes-greffes et empêchent la formation de tissu cicatriciel.
Abstract:
Recombinant neu receptor stimulating factor, analogs of the factor, DNA sequences encoding the same, and methods of production are disclosed. Pharmaceutical compositions and methods of treating disorders involving neu receptor expression are also described.
Abstract:
Pharmaceutical formulations comprising aromatic polycyclic dione compounds useful for treating mammals suffering from diseases caused by retroviruses are disclosed herein. A method for treating mammals suffering from retrovirus infections is also disclosed.
Abstract:
A supported, mechanically stable bipolar membrane (1) for electrodialysis having a cation-exchange layer on one side and an anion-exchange layer on the other side of a single sheet of woven fabric. The cation exchange layer is heterogeneous, the anion exchange layer is homogeneous and the two are interlocked. A process of making such bipolar membranes is described. The bipolar membrane may be fabricated into electrodialysis cells in which two membranes are joined along their edges.
Abstract:
Antibodies to TNF Binding Protein I (TBP-I) and F(ab) fragments thereof are provided that can be used in diagnostic assays and pharmaceutical agents for either inhibiting or mimicking the effects of TNF on cells.
Abstract:
A method of producing a desired hologram for a holographic optical element for use in imaging a multi-dimensional array of points, in which two coherent recording beams are utilized to produce an interference pattern which is recorded to form the desired hologram, characterized in that one or both of the recording beams have an aspherical wavefront derived from one or more intermediate holograms each reconstructed by the use of a read out beam having a geometry and/or wavelength different from the beams for recording the respective intermediate hologram.
Abstract:
An electron multiplier including a multi-layer arrangement of material which provides secondary electron emissions when impinged upon by electrons and apparatus for applying an electric field across the material. A cathode ray tube, and devices incorporating a cathode ray tube, such as televisions and oscilloscopes are also provided in accordance with the invention.
