Production and Use of Anti-Dorsalizing Morphogenetic Protein
Moos, M., Jr., Krinks, M., Wang, S. (FDA)
Filed 8 Nov 94
Serial No. 08/335,583.
In recent years, a number of members of the TGF-
superfamily have been discovered which serve as growth factors in the
development of bone, or participate in a variety of developmental
processes. This case discloses a novel member of the TGF-
superfamily, designated Anti-dorsalizing morphogenetic protein-1, or
ADMP-1. ADMP-1 is most closely related to human bone morphogenetic
protein-3, and counters dorsalizing influences during development.
ADMP-1 can be used as a pharmaceutical to treat inappropriate
proliferation of neural crest derivative tissues, such as
neuroblastomas, as well as a probe for finding and cloning other ADMPs.
The case claims isolated ADMP-1, pharmaceutical preparations employing
ADMP-1, diagnosis of genetic lesions involving this protein, and
methods of treatment of conditions involving inappropriate
proliferation of tissues by administering ADMP-l. [portfolio: Cancer--

Improvements in the Ability of Neural Networks, Particularly Dystal, To
Distinguish Among Small Differences in Similar Inputs
Alkon, D.L., Vogl, T.P. (NINDS)
Filed 14 Nov 94
Serial No. 08/331,554.
This application describes a powerful associative learning neural
network system and improvements designed to enhance decision making.
This invention consists of a basic architectural unit of certain inputs
and outputs. Interposed between inputs and outputs are ``patches'' or
storage areas of dynamic interaction between conditioned and
unconditioned signals. The patches process information to achieve
associative learning locally under rules designed for application-
related goals of the system. This technology far exceeds the power and
utility of previous neural networks with features such as: rapid
incremental learning without supervision, self organizing and
insensitive to global parameters, and associates extremely noisy and
heterogeneous patterns. The utility of this technology has been proven
with complex experimental applications. [portfolio: Devices/

Fluorescent and NMR Sensitive Intracellular pH Indicators
London, R.E. Levy, L.A., Murphy, E., Gabel, S. (NIEHS)
Filed 11 Oct 94
Serial No. 08/320,986.
This invention discloses compositions and methods useful for
measuring pH. Specifically, this invention teaches the measurement of
intracellular pH and a new class of fluorescent and fluorinated (NMR
sensitive) aromatic compounds. These compounds have excitation
wavelengths in the ultraviolet or visible portions of the
electromagnetic spectrum. In addition to being useful for pH
indicators, fluorine containing analogs of these compounds have shown
utility for NMR spectroscopic determinations. The present invention
overcomes the disadvantages of pk values that are not matched to the
cytosol, leaking, and binding to cellular protein, found in current
fluorescent intracellular pH probes. [portfolio: Internal Medicine--

Method and System for Doppler Ultrasound Measurement of Blood Flow
Adam, D.R., Kempner, K.M., Vivino, M.A., Tucker, E.E., Jones, M. (DCRT)
Filed 24 Sep 94
Serial No. 08/300,718
This invention discloses a system and method for providing Doppler
flow velocity data that is corrected for misalignment between the flow
direction within a vessel and the beam orientation of the ultrasound
probe. A conventional ultrasonic Doppler color mapping system was
adapted to include an apparatus to measure and record the free space
position and orientation of the ultrasonic probe. A set of 2D image
planes, which need not be parallel, is acquired. A structural
representation derived from the acquired data is used to determine the
flow direction for the imaged vessel. This apparatus and method has
advantages over other systems because it offers the ability to measure
flow distributions with a hand-manipulated probe. [portfolio: Devices/

Method and System for Multidimensional Localization and Rapid Magnetic
Resonance Spectroscopic Imaging
Posse, S., Le Bihan, D. (CC)
Filed 15 Aug 94
Serial No. 08/290,348 (CIP of 08/224,942).
A newly developed method and system for multidimensional
localization and rapid magnetic resonance spectroscopic imaging allows
for quicker, more accurate imaging of metabolites in biologic tissue.
Nuclear magnetic resonance (NMR) techniques have long been used to
obtain spectroscopic information about substances in order to reveal
the substance's chemical composition. More recently, spectroscopic
imaging techniques have been developed that combine magnetic resonance
imaging (MRI) with NMR spectroscopic techniques, thus providing a
spacial image of the chemical composition; however, previously
available techniques for making such measurements have been hampered by
limitations in prelocalization of samples due to long echo times as
well as long data acquisition times. Most of these systems often
generate spectral as well as spacial data due to the long echo times,
and their localization techniques are not applicable to acquiring
multiple-volume data from nuclei that have short T2 relaxation times.
This new system circumvents these limitations by applying pulse
sequence to a conventional MRI apparatus, which allows the rapid
acquisition of data for generating spectroscopic images and greatly
shortens the echo time. Spatial prelocalization of a volume of interest
is achieved by providing a presuppression sequence before a stimulated
echo (STE) sequence and a suppression sequence before the interval of
the STE sequence. [portfolio: Devices/Instrumentation--Diagnostics,

Method and System For MRI Detection of Abnormal Blood Flow
Moonen, C.T., Duyn, J., van Gelderen, P. (NCRR)
Filed 5 Aug 94
Serial No. 08/286,783.
The present invention disclosure describes a magnetic resonance
imaging system and method for detecting blood flow abnormalities. This
is [[Page 32016]] accomplished by determining the time delay for the
arrival of a bolus of MR contrast agent into a localized region of
tissue. This arrival is observed in a series of magnetic resonance
signals obtained subsequent to the bolus injection. A rapid series of
imaging pulse sequences acquires the time development of the signal
from the localized regions within the imaged field of view of the body.
The arrival time for the bolus into a given localized region is
determined from the acquired time data, and the relative arrival time
among regions in the imaged field of view indicated whether there is
decreased blood flow to certain areas. This method and system has the
potential to replace some of the invasive procedures now in use to
determine blood flow through certain body tissues. [portfolio: Devices/

DNA Sequence Which Acts as a Chromatin Insulator Element To Protect
Expressed Genes From Cis-Acting Regulatory Sequences
Chung, J., Felsenfeld, G. (NIDDK)
Filed 29 Jul 94
Serial No. 08/283,125 (CIP of 08/045,266).
Novel method of insulating functional DNA domains introduced into
higher leukaryotic cells from the effects of the cell's cisacting
regulatory elements. The invention represents the first pure insulator
to be demonstrated to function in human cells. The element promises to
be a useful tool in gene therapy, gene transfer techniques, and studies
involving gene regulation and other gene expression technologies.

Spectroscopic Imaging Device Employing Quality Spectral Filters
Lewis, E.N., Levin, I.W., Treado, P.J. (NIDDK)
Serial No. 08/236,655
Patent Issued 27 Dec 94
U.S. Patent No. 5,377,003.
This novel imaging device, which integrates both light microscopy
and spectroscopy, allows for the cost-effective development of high-
resolution spatial, chemical, and spectral images. It provides a rapid
means for examining and collecting large format images from vibrational
and visible spectra in a three-dimensional sample. It is superior to
current equipment because it has no moving parts. This device may be
used as a tool for the characterization of polymers and semiconductors
and has potential as a diagnostic tool for clinical analysis of
histologic materials. [portfolio: Devices/Instrumentation--Diagnostics,

Method To Enhance the Sensitivity of MRI for Magnetic Susceptibility
Effects
Moonen, C.T. (NCRR)
Filed 13 Aug 93
Serial No. 08/106,372 (CIP of 07/841,994).
A novel fast-imaging method resulting in enhanced sensitivity to
T2* changes was developed. This new technique is unlike other methods
in that it is based on gradient-recalled echoes of spins whose
excitation and echo formation are separated by one or more TR period.
It does not require chemical shift refocusing and, thus, results in
increased T2* sensitivity. The new method improves the ability of
functional MRI based on T2* effects. [portfolio: Devices/
