Method and Apparatus to Improve an MRI Image

Peter Kellman and Elliot McVeigh (NHLBI)

DHHS Reference No. E-361-01/0 filed Oct 19, 2001

Licensing Contact: Dale Berkley; 301/496-7735 ext. 223; e-mail:

The invention is a method for improving image quality in MR imaging methods using the SENSE (SENSitivity Encoding) method, which is known to have degraded image quality due to numerical ill-conditioning (so called g-factor loss). The invention improves the numerical conditioning by means of an adaptive regularization (matrix conditioning), thereby improving image quality for a given scan time. This is accomplished by adaptively adjusting the regularization parameter for each pixel position to achieve a target ghost artifact suppression. In this manner, a higher degree of matrix conditioning is used in regions which have less artifact, thus improving the SNR in these regions.

Use of CpG Oligodeoxynucleotides to Encourage Angiogenesis

Dennis M. Klinman (FDA), Mei Zheng (EM), Barry T. Rouse (EM) Start Printed Page 11350

DHHS Reference No. E-328-01/0 filed Dec 20, 2001

Licensing Contact: Peter Soukas; 301/496-7056 ext. 268; e-mail:

This invention relates to the field of angiogenesis, more specifically to the use of CpG oligonucleotides to promote angiogenesis. Angiogenesis, the process of developing a hemovascular network, is essential for the growth of solid tumors and is a component of normal wound healing and growth processes. It has also been implicated in the pathophysiology of atherogenesis, arthritis, corneal neovascularization, and diabetic retinopathy. Angiogenesis factors play an important role in wound healing and likely play a role in the development of malignancies; hence, it would clearly be advantageous to identify new angiogenic agents.

CpG oligodeoxynucleotides (ODNs) express a wide range of biological activities. They are potent vaccine adjuvants, anti-allergens, and trigger a protective innate immune response. Several recent reports indicate that CpG ODN also stimulate cells of the central nervous system. Although CpG ODN have many potential uses, their potential to induce angiogenesis has not been previously recognized. The inventors have shown that bioactive CpG motifs induce dose-dependent neovascularization in the corneas of mice. The invention claims methods for stimulating angiogenesis using CpG ODNs, methods for inducing the production of VEGF (Vascular Endothelial Growth Factor) using CpG ODN, and a model system for screening potential anti-angiogenic agents.

Vaccine for Protection Against Shigella sonnei Disease

Dennis J. Kopecko, De-Qi Xu, John O. Cisar (FDA)

DHHS Reference No. E-210-01/0 filed Jan 16, 2002

Licensing Contact: Peter Soukas; 301/496-7056 ext. 268; e-mail:

Shigellosis is a global human health problem. Transmission usually occurs by contaminated food and water or through person-to-person contact. The bacterium is highly infectious by the oral route, and ingestion of as few as 10 organisms can cause an infection in volunteers. An estimated 200 million people worldwide suffer from shigellosis, with more than 650,000 associated deaths annually. A recent CDC estimate indicates the occurrence of over 440,000 annual shigellosis cases in the United States alone, approximately eighty percent (80%) of which are caused by Shigella sonnei. Shigella sonnei is more active in developed countries. Shigella infections are typically treated with a course of antibiotics. However, due to the emergence of multidrug resistant Shigella strains, a safe and effective vaccine is highly desirable. No vaccines against Shigella infection currently exist. Immunity to Shigellae is mediated largely by immune responses directed against the serotype specific O-polysaccharide. Claimed in the invention are compositions and methods for inducing an immunoprotective response against S. sonnei. Specifically, an attenuated bacteria capable of expressing an S. sonnei antigen comprised of the S. sonnei form I O-polysaccharide expressed from the S. sonnei rfb/rfc gene cluster is claimed. The inventors have shown that the claimed vaccine compositions showed one hundred percent (100 %) protection against parenteral challenge with virulent S. sonnei in mice.

Method for Determining Sensitivity to a Bacteriophage

Carl R. Merril (NIMH), Sankar Adhya (NCI), Dean M. Scholl (NIMH)

DHHS Reference No. E-318-00/0 filed Jan 22, 2002

Licensing Contact: Peter Soukas; 301/496-7056, ext. 268; e-mail:

Traditionally, chemical antibiotics have been used to treat a variety of bacterial infections. However, bacterial resistance to current antibiotics is an increasingly serious problem in human and veterinary health as well as agriculture. Many experts believe that strains of disease-causing bacteria resistant to all common antibiotics will arise in the next ten to twenty years. Bacteriophages offer a promising therapeutic alternative to antibiotics for these antibiotic resistant bacteria. There are also situations in which bacteriophage may be more suitable than antibiotics to treat infections caused by against antibiotic-sensitive bacteria. Bacteriophages are highly host-specific, thus determining whether a phage would be therapeutically useful against a particular bacterium or strain of bacteria is very important but can be a time-consuming and labor-intensive process.

The current invention claims a method for selecting a therapeutic bacteriophage that would be effective against a particular disease-causing bacteria, comprising a number of bacteriophages containing reporter nucleic acids capable of being expressed when the bacteriophage infects a bacterial cell. These bacteriophages are separately contacted with a sample contaminated by a bacterium. Expression of the reporter is then detected, indicating which bacteriophage has infected a bacterial cell and is thus a potential therapeutic phage against the particular bacteria. Also claimed in the application are kits allowing for the rapid identification of potentially therapeutic bacteriophages.
