This invention relates to a strain of Moraxella catarrhalis containing a gene mutation that prevents endotoxic lipooligosaccharide (LOS) synthesis and potential use of the mutant for developing novel vaccines against the pathogen, for which there is currently no licensed vaccine. M. catarrhalis is one of the causative agents of otitis media (middle ear infection), sinusitis, and lung infections. The mutant is defective in the lpxA gene, whose enzyme product is relevant in lipid A biosynthesis (lipid A is part of the LOS).

The identified technologies describe self-replicating infectious recombinant paramyxoviruses with one or more attenuating mutations, such as a separate variant polynucleotide encoding a P protein and a separate monocistronic polynucleotide encoding a V protein, or at least one temperature sensitive mutation and one non-temperature sensitive mutation. Compositions and methods for recovering, making and using the infectious, recombinant paramyxoviruses as described are also included (e.g. recombinant human parainfluenza virus type 2 (HPIV2)).

MRI is a promising imaging modality that provides superior soft tissue contrast and multi planar real-time imaging without harmful ionizing radiation for therapeutic procedures. Interventional magnetic resonance imaging (iMRI) has gained important popularity in many fields such as interventional cardiology and radiology, owing to the development of minimally invasive techniques and visible catheters under MRI for conducting MRI-guided procedures and therapies.

The complexity of taste discrimination (salty, sour, sweet, umami and bitter) varies between human individuals and populations. Sweet and umami (the taste of glutamate) tastes play a major role in the perception of calorically-rich and essential nutrients and there are well-documented differences in individual perception of sweet and umami flavorings, many of which appear to be genetic in origin.

Available for licensing and commercial development are novel biotechnological tools, prophylactics, therapeutics, and methods for modulating the activation state of an antigen presenting cell (APC) and thereby modulating the activation of a killer T cell.

ADP-ribosylation is important in many cellular processes, including DNA replication and repair, maintenance of genomic stability, telomere dynamics, cell differentiation and proliferation, and necrosis and apoptosis. Poly-ADP-ribose is important in a number of critical physiological processes such as DNA repair, cellular differentiation, and carcinogenesis. Until recently, only one human enzyme, PARG, had been identified that degrades the ADP-ribose polymer.

Reactivation of latent Varicella-Zoster virus (VZV) infection is the cause of shingles, which is prominent in adults over the age of 60 and individuals who have compromised immune systems, due to HIV infection, cancer treatment and/or transplant. Shingles is a worldwide health concern that affects approximately 600,000 Americans each year. The incidence of shingles is also high in Europe, South America, and India; the latter having an estimated two million individuals affected, yearly.

Podocytes, cells of the visceral epithelium in the kidneys, are a key component of the glomerular filtration barrier. As such, they play a vital role in glomerular disorders, which are a major cause of chronic kidney disease. Examples of these disorders include focal segmental glomerulosclerosis, membranous glomerulonephritis, minimal change disease, and diabetic nephropathy.

Anthrax, whether resulting from natural or bioterrorist-associated exposure, is a constant threat to human health. The lethality of anthrax is primarily the result of the effects of anthrax toxin, which has 3 components: a receptor-binding protein known as "protective antigen" (PA) and 2 catalytic proteins known as "lethal factor" (LF) and "edema factor" (EF). Although production of an efficient anthrax vaccine is an ultimate goal, the benefits of vaccination can be expected only if a large proportion of the population at risk is immunized.
