Tetracycline-responsive transcriptional activator driven by the liver-specific mouse albumin promoter (Alb-tTA).

Tetracycline-responsive transcriptional activator driven by the liver-specific mouse major urinary protein promoter (MUP-tTA).

Cyclodextrins (CD), alone or in combination with other agents (e.g., vitamin E), as therapeutics for the treatment of lysosomal storage disorders (LSDs) caused by the accumulation of non-cholesterol lipids.

Novel tocopherol derivatives and tocopheryl quinone derivatives useful in the decrease of lysosomal substrate accumulation, the restoration of normal lysosomal size, and the treatment of lysosomal storage disorders (LSDs) are provided. The inventors have discovered that tocopherol and tocopheryl quinone derivatives with side chain modifications (such as terminal tri-halogenated methyl groups) exhibit improved pharmacokinetics, modulation of mitochondrial potential and restoration of some LSDs phenotypes.

A specific and sensitive TaqMan-based real-time (rt) RT-PCR assay has been developed by CDC scientists for detection of noroviruses in clinical and environmental specimens. This assay can be implemented to rapidly detect and distinguish norovirus strains from genogroups I and II, which are responsible for the majority of human infections. Additionally, the assay is multiplexed with an internal extraction control virus (coliphage MS2) to validate the results of the assay.

This invention relates to synthetic immunoreactive peptides, which are portions of the M proteins of the most prevalent Group A Streptococcus (GAS) serotypes in the United States. These peptides may be useful in development of a flexible, multivalent GAS vaccine. They can be recognized by M type-specific antibodies and are capable of eliciting functional opsonic antibodies. Additionally, the peptides or isolated antibodies raised in response to the peptides may be useful for GAS diagnostics.

This Intranasal Dry Powder Inhaler (DPI), developed with Creare, Inc., allows low-cost delivery of powder vaccines. Nasal delivery has numerous advantages compared to traditional injected vaccines, including: 1) safe, needle-less administration by minimally-trained staff or patient; 2) better protection due to mucosal and cross-protection; and 3) decreased biohazard waste.

Intranasal delivery is a simple, inexpensive and needle-free route for administration of vaccines and therapeutics. This intranasal delivery technology, developed with Creare LLC., includes low-cost, disposable drug cartridges (DDCs) that mate with a durable hand-held device. The rechargeable-battery-powered device transmits ultrasonic energy to the DDC to aerosolize the drug and is capable of performing for eight hours at 120 vaccinations per hour. Potential applications for this platform technology include intranasal vaccination (e.g.

This nucleic acid assay employs Light Upon Extension (LUX) chemistry and High Resolution Melt (HRM) analysis to detect and distinguish the different genotypes of Chlamydophila psittaci. C. psittaci is an atypical pathogen which may result in severe pneumonia upon infection of birds, mammals and humans (depending on inter-relationships between host and pathogen genotypes). Presently, C. psittaci clinical identification is achieved by a cumbersome and time-intensive mix of ompA gene sequencing, microarray analysis, RFLP and/or serological testing.

CDC researchers have developed algorithmic methods for determining sigmoid curve optimums and calculating component concentrations. Sigmoid curves are commonly generated in bioassays and used to calculate results. Various techniques have been used to define the curve, analyze the observations, and calculate a concentration. This technology is an algorithmic approach to identifying the usable portion of a sigmoid curve.
