Abstract: An example system and method of reconstructing biological activation information are disclosed. A first biological signal and a second biological signal associated with an organ are processed via a computing device to determine whether there is a point of change in a derivative of the first biological signal with respect to a derivative of the second biological signal above a threshold. An activation onset time is assigned in the first biological signal at the point of change to define biological activation associated with the organ in the first biological signal if it is determined that the point of change is above the threshold.

Abstract: A functionalized active-nucleus complex sensor that selectively associates with one or more target species, and a method for assaying and screening for one or a plurality of target species utilizing one or a plurality of functionalized active-nucleus complexes with at least two of the functionalized active-nucleus complexes having an attraction affinity to different corresponding target species. The functionalized active-nucleus complex has an active-nucleus and a targeting carrier. The method involves functionalizing an active-nucleus, for each functionalized active-nucleus complex, by incorporating the active-nucleus into a macromolucular or molecular complex that is capable of binding one of the target species and then bringing the macromolecular or molecular complexes into contact with the target species and detecting the occurrence of or change in a nuclear magnetic resonance signal from each of the active-nuclei in each of the functionalized active-nucleus complexes.

Abstract: Boron neutron capture therapy can utilize XyB20H17L where X is an alkali metal, y is 1 to 4, and L is a two electron donor such as NH3, and Na2B10H9NCO, among others. These borane salts may be used free or encapsulated in liposomes. Liposomes may also have embedded within their bilayers carboranes to increase the amount of delivered 10B and/or to increase the tumor specificity of the liposome.

Abstract: The present invention provides compositions comprising colorimetric assay liposomes. The present invention also provides methods for producing colorimetric liposomes and calorimetric liposome assay systems. In preferred embodiments, these calorimetric liposome systems provide high levels of sensitivity through the use of dopant molecules. As these dopants allow the controlled destabilization of the liposome structure, upon exposure of the doped liposomes to analyte(s) of interest, the indicator color change is facilitated and more easily recognized.

Perc1ace is a gram-negative, curved rod, facultative anaerobe which is deposited with the American Type Culture Collection under ATCC No. 202172. Perc1ace may be used as a substitute for anaerobic bacteria which are presently being used in biological systems for removing perchlorate and/or nitrate from water and other contaminated materials, such as soil.

Abstract: The invention provides fragments of GAD.sub.65 that are specifically reactive with at least one class of GAD.sub.65 autoantibody. Most fragments are substantially free of N-terminal amino acids that would otherwise limit solubility. Different fragment contain epitopes for different classes of GAD.sub.65 autoantibodies. The fragments are used in methods of diagnosing and treating insulin dependent diabetes mellitus and stiff man syndrome.

Abstract: The invention provides new methods for screening libraries of peptides and other compounds for a desired property in eucaryotic cells. The methods are premised, in part, on the unexpected observation that the contents of procaryotic or lower eucaryotic cells, such as yeast, can be transferred to recipient eucaryotic cells in an essentially clonal manner by protoplast fusion of the respective cells. Applications of the methods include screening peptides in eucaryotic cells substantially incapable of episomal replication of transferred nucleic acid fragments; screening in eucaryotic cells peptides or secondary metabolites produced in procaryotic cells; and screening a library of peptides for capacity to bind a selected RNA in eucaryotic cells.
