Rapid Motion Perception MRI Navigator Method

Available for licensing and commercial development is a non-breathhold flow sensitive navigator technique for reducing respiratory motion artifacts in magnetic resonance (MR) images. The method, called Rapid Motion Perception (RaMP), tracks bulk translational motion of the heart in real-time. The position of the blood volume is a direct representation of the heart position. RaMP tracks fast-moving blood volume during systole as a marker for the heart position, while suppressing stationary or slow moving spins.

Variable Curve Catheter

The invention provides a deflectable tip guiding device, such as a catheter, that enables the operator to vary the radius of curvature of the tip of the catheter. This is a novel variation on the classic "fixed fulcrum" tip deflectors used in minimally invasive procedures in open surgical treatments. The described device permits a more comprehensive ability to navigate complex geometric pathways in patient's body and enables better access to target structures (e.g., to all endomyocardial walls from a transaortic approach).

Isolation of Hybridomas Producing Monoclonal Antibodies (MAbs) Inhibitory to Human CYP2J2

The National Institutes of Health announces three specific monoclonal antibodies that strongly inhibit and/or immunoblot the human cytochrome P450 2J2 (CYP2J2).

Cytochrome P450s catalyze the NADPH-dependent oxidation of arachidonic acid to various eicosanoids found in several species. The eicosanoids are biosynthesized in numerous tissues including pancreas, intestine, kidney, heart and lung where they are involved in many different biological activities.

Peptide Mimotope Candidates for Otitis Media Vaccine

This technology describes peptide mimotopes of lipooligosaccharides (LOS) from nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis that are suitable for developing novel vaccines against the respective pathogens, for which there are currently no licensed vaccines. The mimotopes not only immunologically mimic LOSs from NTHi and M. catarrhalis but will also bind to antibodies specific for the respective LOS. NTHi and M. catarrhalis are common pathogens that cause otitis media in children and lower respiratory tract infections in adults.

Vaccines Comprising Sand Fly Salivary Proteins for Control of Leishmania Infection

This invention relates to the use of several peptides from the salivary glands of various sand fly species for the control of leishmania infection. Many of these peptides were shown to be effective in eliciting potent immune responses in animal models and are excellent candidates for the development of vaccines against the disease. A vaccine comprising one of the peptides was used to protect mice challenged with parasites and salivary gland homogenates.

Enzymatically-Active RNA-Dependent RNA Polymerase From a Human Norovirus (Calicivirus)

The noroviruses (formerly known as “Norwalk-like viruses”) are associated with gastroenteritis outbreaks, affecting large numbers of individuals each year. Emerging data are supporting their increasing recognition as important agents of diarrhea-related morbidity and mortality. The frequency with which noroviruses are associated with gastroenteritis as “food and water-borne pathogens” has led to the inclusion of caliciviruses as Category B Bioterrorism Agents/Diseases.

Construction of Recombinant Baculoviruses Carrying the Gene Encoding the Major Capsid Protein, VP1, From Calicivirus Strains (Including Norovirus Strains Toronto, Hawaii, Desert Shield, Snow Mountain, and MD145-12)

The noroviruses (known as "Norwalk-like viruses") are associated with an estimated 23,000,000 cases of acute gastroenteritis in the United States each year. Norovirus illness often occurs in outbreaks, affecting large numbers of individuals, illustrated recently by well-publicized reports of gastroenteritis outbreaks on several recreational cruise ships and in settings such as hospitals and schools. Norovirus disease is clearly important in terms of medical costs and missed workdays, and accumulating data support its emerging recognition as important agents of diarrhea-related morbidity.

Construction of an Infectious Full-Length cDNA Clone of the Porcine Enteric Calicivirus RNA Genome

Porcine enteric calicivirus (PEC) is a member of the genus Sapovirus in the family Caliciviridae. This virus causes diarrheal illness in pigs, and is presently the only enteric calicivirus that can be grown in cell culture. In addition to its relevance to veterinary medicine as a diarrheal agent in pigs, PEC serves as an important model for the study of enteric caliciviruses that cause diarrhea and that cannot be grown in cell culture (including the noroviruses represented by Norwalk virus).

Multimeric Protein Toxins to Target Cells Having Multiple Identifying Characteristics

This technology relates to multimeric bacterial protein toxins which can be used to specifically target cells. Specifically, this is a modified recombinant anthrax toxin protective antigen (PrAg) that has been modified in several ways. First, the PrAg can be activated both by a metalloproteinase (MMP) and by urokinase plasminogen activator (uPA). Second, the native PrAg lethal factor (LF) binding site has been modified so that only a modified PrAg comprising two different monomers can bind anthrax LF.
