Title: Tissue paper containing chemically softened coarse cellulose fibers
Inventor: DEASON HOWARD THOMAS
IPC: D21H17/14
Filed: 1997-03-13
Abstract: Tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and napkins are provided. The composite average coarseness of the tissue papers is between about 11 mg/100 m and about 18 mg/100 m.

Title: Sensors for detecting analytes in fluids
Inventor: LEWIS NATHAN S
IPC: G01N27/12
Filed: 1997-08-11
Abstract: Chemical sensors for detecting analytes in fluids comprise first and second conductive elements (e.g., electrical leads) electrically coupled to and separated by a chemically sensitive resistor which provides an electrical path between the conductive elements. The resistor comprises a plurality of alternating nonconductive regions (comprising a nonconductive organic polymer) and conductive regions (comprising a conductive material) transverse to the electrical path. The resistor provides a difference in resistance between the conductive elements when contacted with a fluid comprising a chemical analyze at a first concentration, than when contacted with a fluid comprising the chemical analyte at a second different concentration. Arrays of such sensors are constructed with at least two sensors having different chemically sensitive resistors providing dissimilar such differences in resistance. Variability in chemical sensitivity from sensor to sensor is provided by qualitatively or quantitatively varying the composition of the conductive and/or nonconductive regions. An electronic nose for detecting an analyte in a fluid may be constructed by using such arrays in conjunction with an electrical measuring device electrically connected to the conductive elements of each sensor.

Title: A therapeutic agent for ischemic diseases
Inventor: KONISHI JIN-EMON
IPC: A61K35/36
Filed: 1999-04-27
Abstract: The invention relates to a therapeutic agent for ischemic diseases having little side effects and being capable of administering safely. The effective component of the therapeutic agent for ischemic diseases of the present invention is an extract from inflammatory tissue inoculated with vaccinia virus. An extract from inflammatory tissue inoculated with vaccinia virus. protects a cell against damage by suppressing abnormal depolarization of hippocampal pyramidal neurons during hypoxia and so can delay the time falling into cell death. The characteristic action is not observed for normal pyramidal neurons, but is expressed only in the stage of pathema during hypoxia. Therefore, the substance of the present invention is useful as a drug to treat and prevent ischemic diseases such as cerebral infarction and the like and symptoms accompanying with neuropathy caused by ischemia.
