摘要:
Chimeric parainfluenza viruses (PIVs) incorporate a PIV vector genome or antigenome and one or more antigenic determinant(s) of a heterologous PIV or non-PIV pathogen. These chimeric viruses are infectious and attenuated in humans and other mammals and are useful in vaccine formulations for eliciting an immune responses against one or more PIVs, or against a PIV and non-PIV pathogen. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric Ply genome or antigenome which includes a partial or complete PIV vector genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) encoding antigenic determinant(s) of a heterologous PIV or non-PIV pathogen.
摘要:
Isolated polynucleotide molecules provide recombinant PIV genomes and antigenomes for production of recombinant PIV vaccines. The recombinant genome or antigenome can be expressed with a nucleoprotein (N), phosphoprotein (P), and a large (L) polymerase protein to produce isolated infectious PIV particles. The recombinant PIV genome and antigenome can be modified to produce desired changes, for example to incorporate attenuating mutations from biologically derived PIV mutants or to create chimeric PIV clones, to generate attenuated, immunogenic viruses for vaccine use.

Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an anti-PIV immune response or as vectors for introducing heterologous genes into a host. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different PIV virus to form the human-bovine chimeric PIV genome or antigenome.
摘要:
The present invention is directed to radiolabeled epibatidine analogues, specifically FPH labeled with radioisotopes of fluorine and/or carbon. These radiolabeled epibatidine compounds are used to noninvasively image and quantify nicotinic cholinergic receptors in the living brain for both research studies and the diagnosis of neurodegenerative diseases.
摘要:
The present invention provides stable compounds prepared from boronic acid and lyophilized compounds thereof of the formula (1): 1 in which Z1 and Z2 are moieties derived from sugar. The invention also provides methods for preparing such compounds. Lyophilizing a mixture comprising a boronic acid compound and a moiety derived from sugar produces a stable composition that readily releases the boronic acid compound upon reconstitution in aqueous media.

A conjugate comprising a compound as described above and a carrier agent, a composition comprising (i) a compound or a conjugate as described above and (ii) a carrier, a method of inhibiting binding of an SH2 domain in a protein comprising an SH2 domain to a target protein in an animal, wherein the SH2 domain is contacted with a target protein-binding inhibiting effective amount of a compound or a conjugate as described above, and a method of synthesizing such conjugates.
摘要:
We disclose a combinatorial, hierarchical process that uses nullprocess-patternsnull in one preferred embodiment to identify, classify, and compare substrings within strings; and in another preferred embodiment to identify, classify, compare, generate, and separate fragments derived from one or more physical samples of polynucleotides. These substrings (and their physical polynucleotide counterparts) are called nullpartitionnull fragments, and the process-pattern-defined derivatives that some, but not all, nullpartitionnull fragments may yield are called nullstructured query fragmentsnull (SQFs). A process-pattern is both: (i) an ordered set of short nulltargetnull (one from each major search class) sites that must be present (and whose higher-ranked members of the same major search class must not have any sites) within the relevant search area of a partition fragment, and (ii) a step-wise delimitation process (where each step has a defined polarity and occurs after a target is found) that restricts the region of a partition fragment where the next class-specific, pre-emptive target-search takes place. In one preferred embodiment, the computer software disclosed herein locates the process-patterns and SQFs of interest within the partition fragments in the string(s) under study (e.g., a set of polynucleotide sequence data), stores the results, and provides for access to this data by database query and analysis tools. These computational analyses are emulated by another preferred embodiment using physical samples of polynucleotides and the laboratory methods disclosed herein. In the latter, sequence-specific, double-stranded cleavage effectors utilize as substrates and generate as products progressively expanding sets of asymmetrically end-immobilized DNA, a process that ultimately yields extremely large numbers of individually distinguishable SQFs (called nullrangednull SQFs) with lengths between 100-700 nucleotides. In almost all cases, the known process-pattern and observed length of an experimentally obtained ranged SQF provide sufficient information for the computer software disclosed herein to map the ranged SQF automatically to its partition fragment (and location) within a set of polynucleotide sequence data that characterizes the physical sample(s) of polynucleotides under study.
