This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Rapid Universal and/or Type-Specific Assay for Clostridium Botulinum
Description of Technology: The urgent need for a rapid diagnostic test capable of detecting all serotypes of C. botulinum is well known. Botulinum neurotoxins (BoNTs) are the most potent biological toxins known and are categorized as category A biodefense agents because of lethality and ease of production. Current diagnostic methods include clinical observation of symptoms that could be mistaken for other neurological conditions and a mouse protection bioassay that takes as long as four days and has a number of disadvantages. The subject technology utilizes unique PCR primers for the detection of the non-toxin non-hemaglutinin (NTNH) gene of C. botulinum; this gene is highly conserved in all C. botulinum toxin types and subtypes. Thus, samples that contain botulinum can be determined regardless of serotype involved, providing a universal means of diagnosis. Further, the technology describes different PCR primers and flurogenic probes for a BoNT-specific assay. The type-specific assay can be used independently or in conjunction with the universal assay described above. The universal and type-specific assays were successfully used first to Start Printed Page 14125identify positively botulinum DNA samples in a test of botulinum and non-botulinum clostridia species then to determine the toxin type. The diagnostic testing described by the subject technology requires significantly less time than the current gold standard diagnostic test.
Applications: (1) Universal diagnostic test for C. botulinum; (2) Diagnostic test for C. botulinum capable of detecting all seven toxin types; (3) Combination diagnostic.

Methods and Compositions for Protecting Cells From Ultrasound-Mediated Cytolysis
Description of Invention: Available for licensing and commercial development are methods for protecting cells from ultrasound-mediated cytolysis. The in vitro exposure of cells to ultrasound and the therapeutic uses of ultrasound (e.g., sonoporation, thrombolysis, HIFU, sonophoresis, acoustic hemostasis) may induce changes in tissue state, including apoptosis and cytolysis, through thermal effects (e.g., hyperthermia), mechanical effects (e.g., acoustic cavitation or through radiation force, acoustic streaming and other ultrasound induced forces), and chemical effects (via sonochemistry or by the activation of solutes by sonoluminescence). Ultrasound exposure conditions in these biomedical and in biological processes (e.g. ultrasound bioreactors) are limited by the need to increase the beneficial effects of ultrasound, while at the same time limiting the detrimental effects, such as apoptosis and cytolysis. Accordingly, the protecting molecules used to carry out the methods of the invention possess the ability to protect cells against ultrasound mediated cytolysis, without hindering ultrasound induced physical effects that could be utilized to create beneficial effects. The protecting solutes are surface active and possess at least one “carbohydrate unit” as described. The solutes include, but are not limited to: alkyl-β-D-thioglucopyranoside, alkyl-β-D-thiomaltopyranoside, alkyl-β-D-galactopyranoside, alkyl-β-D-thiogalactopyranoside, or alkyl-β-D-maltrioside, hexyl-β-D-glucopyranoside, heptyl-β-D-glucopyranoside, octyl-β-D-glucopyranoside, nonyl-β-D-glucopyranoside, hexyl-β-D-maltopyranoside, n-octyl-β-D-maltopyranoside, n-octyl-β-D-thioglucopyranoside, 2-propyl-1-pentyl-β-D-maltopyranoside, methyl-6-O-(N-heptylcarbamoyl)-α-D-glucopyranoside, 3-cyclohexyl-1-propyl-β-D-glucoside, 6-O-methyl-n-heptylcarboxyl-α-D-glucopyranoside.
