Title: Methods and compositions based on inhibition of cell invasion and fibrosis by anionic polymers
Inventor: ROUFA DIKLA
IPC: A61P17/02
Filed: 1992-05-29
Abstract: The present invention relates to the discovery that biocompatible anionic polymers can effectively inhibit fibrosis, scar formation, and surgical adhesions. The invention is predicated on the discovery that anionic polymers effectively inhibit invasion of cells associated with detrimental healing processes, and in particular, that the effectiveness of an anionic polymer at inhibiting cell invasion correlates with the anionic charge density of the polymer. Thus, the present invention provides a large number of materials for use in methods of inhibiting fibrosis and fibroblast invasion.  Anionic polymers for use in the invention include but are not limited to natural proteoglycans, and the glycosaminoglycan moieties of proteoglycans. Additionally, anionic carbohydrates and other anionic polymers may be used. The anionic polymers dextran sulfate and pentosan polysulfate are preferred. In a more preferred embodiment, dextran sulfate, in which the sulfur content is greater than about 10 % by weight, may be used. In a more preferred embodiment, the average molecular weight is about 40,000 to 500,000 Daltons. The present invention provides compositions and methods to inhibit fibrosis and scarring associated with surgery. The invention further provides compositions and methods to inhibit glial cell invasion, detrimental bone growth and neurite outgrowth. In a preferred embodiment, the inhibitory compositions further comprise an adhesive protein.

Title: Sea cape
Inventor: RODGER MALCOLM D
IPC: H01Q15/14
Filed: 1994-08-17
Abstract: The survival of life at sea in a man overboard or abandonment situation  is  largely  dependant on the  searcher being able  to quickly locate and identify survivors and survival craft in the water.     The sea cape is a special fabric that spreads out on the water astern of the individual units and is constructed in such a way as to provide a much greater visible target and a radar target that can be easily identified as artificial.     Alternating  panels  of  contrasting  colours  layered  over alternating panels of radar absorptive and radar reflecting panels all together in a thin positive buoyancy fabric will allow positive identification in the zero to eight mile surface search range and not be greatly affected by sea conditions.     Airborne searchers will have a five hundred to one thousand percent bigger target to search for.

Inventor: JONES RONALD H JR
IPC: G10L19/00
Filed: 1994-12-23
Abstract: Digitized audio information is compressed by retrieving a first audio sample from a digitized audio signal and storing it in its entire, uncompressed, form. The next audio sample is then retrieved and a signed difference between the first audio sample value and the next audio sample value is computed. If this difference value can be represented in fewer data segments than would be required to represent the next audio sample, the difference value is stored, rather than the value of the next sample, otherwise the next sample is stored. The invention proceeds in this fashion until the entire PCM audio signal is compressed and stored. The compressed data stream is decompressed to generate an output data stream by retrieving a stored sample and examining it to ascertain whether it is a difference value or a flag which indicates that the following data represents a coded amplitude value. If the sample is a difference value it is digitally added to the previous value (taking into account the sign) and the sum is inserted into the output data stream. The sum value is retained in order to be used to compute the next output value if the following sample is also a difference value. Alternatively, if the sample is a flag value it is discarded and the next sample is retrieved and inserted into the output data stream.

Filed: 1993-08-09
Abstract: Disclosed are antibodies to peptides active in the structuredness of the cytoplasmic matrix test (SCM-factor peptides) and to fragments of the peptides by immunization of antibody-producing animals with the peptides or fragments. Both polyclonal and monoclonal antibodies can be prepared. Particularly useful are antibodies specifically binding the peptides M-I-P-P-E-V-K-F-N-K-P-F-V-F-L-M-I-D-Q-N-T-K-V-P-L-F-M-G-K (SEQ ID NO: 2) and F-L-M-I-D-Q-N-T-K (SEQ ID NO: 3). The antibodies can be labeled and are suitable for performing immunoassays to detect the presence of SCM  cancer-recognition factors in cell cultures or body fluids. One particularly useful immunoassay can distinguish SCM factor from partially homologous peptide sequences, and comprises: (a) incubating a first aliquot of the sample with a first antibody specific for the cancer-recognition factor to bind the first antiboby to the cancer-recognition factor in the first aliquot; (b) reacting a second aliquot of the sample with a second antiboby specific for the amino-terminal portion of the partially homologous peptide sequence to bind the second antibody to the partially homologous peptide sequence in the second aliquot; and (c) comparing the quantity of the first antibody bound to the first aliquot with the quantity of the second antibody bound to the second aliquot to detect the cancer recognition factor.

Abstract: A television receiver having a microprocessor controlled disturbance control system that can operate totally under user control or automatically.  The microprocessor generates an on-screen menu which presents noise control options to the user.  In the preferred embodiment, the menu options allow the user to ameliorate the effects of impulse noise disturbances, longer duration disturbances, continuous wave form (CW) disturbances, or some combination of the three, without requiring the user to understand the nature of these disturbances.  The present invention also provides compensation circuitry for reducing the effects of impulse noise in the video signal that is controlled by responding to the high frequency luminance signal produced by a comb filter, and also responding to the composite video picture signal.  High frequency luminance and amplitude variations that are outside of the composite video signal range are indicative of the presence of impulse noise.  These variations are detected and used to produce a control signal for activating tracking and hold circuitry for reducing the effect of the impulse.
