Abstract: A method of increasing the wet strength of a creped sheet, which method involves providing a sheet (36) which includes cellulosic fibers, which sheet has a first side and a second side; applying (50) a low temperature-curing latex adhesive binder composition (58) to the first side of the sheet (36) in a fine, spaced-apart pattern occupying from about 20 to about 50 percent of the surface area of the sheet; adhering the first side of the sheet (36) to a creping surface; and creping the sheet from the creping surface. The binder composition (58) is adapted to adhere the sheet to the creping surface (60) and includes a functional group-containing latex, a functional group-reactive crosslinking agent, and a volatile base. in addition, the creping surface (60) is heated at a temperature no greater than about 100°C. The low temperature-curing latex adhesive binder composition (58) is adapted to have cured to a level, by the time the sheet is remove from the creping surface, which imparts to the creped sheet a cross-direction wet tensile strength which is at least about 50 percent that of an identical creped sheet which has been heated at about 150 °C for three minutes, in which the cross-direction wet tensile is tested in accordance with TAPPI TM Test Methods T494om-88 and T456om-87. In addition, the cross-direction wet tensile strength of the creped sheet is at least about 40 grams per centimeter.

Title: Construction of retroviral producer cells from adenoviral and retroviral vectors
Inventor: LIN XINLI
IPC: C12N15/09
Filed: 1999-04-29
Abstract: A combination of adenoviral and retroviral vectors used to construct second generation packaging cells that deliver marker genes to target cells is described. A vector based upon Moloney murine leukemia virus (MLV) was used to deliver marker genes, and an adenovirus-based delivery system was used to deliver MLV structural genes (gagpol and env) to cultured cells. The procedure transformed the cells into new retroviral producer cells, which generate replication-incompetent retroviral particles in the culture supernatant for transferring marker genes to target cells. The titer of the retroviralcontaining supernatant generated from the second generation producer cells reached above 105 cfu/ml, which is comparable to the MLV-based producer cell lines currently used in human gene therapy trials. The vector and procedures are adaptable for experimental human gene therapy in which the new producer cells are transplanted into patients for continuous gene transfer.

Title: The use of r-flurbiprofen for the treatment of inflammation
Inventor: WECHTER WILLIAM J
IPC: A61K31/403
Filed: 1999-09-03
Abstract: The present invention relates to the use of an enantiomerically pure R-NSAID  for the manufacture of a medicament for inflammation in an animal, wherein the medicament provides a dose of more than 2.5 milligrams per kilogram of the animal's body weight and wherein the R-NSAID is R-flurbiprofen.  The anti-inflammatory action of R-NSAIDs is due to their ability to interfere with the biosynthesis of COX-2 by inhibiting COX-2 mRNA synthesis, rather than by just blocking the action of the enzyme itself. In order to effect the inhibition of COX-2 mRNA synthesis, the R-NSAID  must be present at relatively high doses. Because the R-NSAID is selective in its action, that is it does not inhibit either COX-1 mRNA synthesis or the COX-1 enzyme itself, it can be administered in the required high doses because the tissue protective effects of prostaglandins made through the COX-1 pathway are not interfered with.

Title: Road surface gradient detecting apparatus
Inventor: SAOTOME HIROSHI
IPC: F16H61/20
Filed: 2001-05-15
Abstract: When a road surface gradient is calculated by a wheel driving force and a vehicle acceleration, if the wheel driving force is calculated based on an output torque of an engine (1), the accuracy of calculating the wheel driving force, i. a., the road surface gradient becomes poor due to deterioration by aging of the engine or the like. In order to solve this kind of disadvantage, a fluid transmission torque (TQtr) of a torque converter (2) is calculated by those torque ratio (.kappa.) of the torque converter (2) and an input shaft torque coefficient (.tau.) which correspond to a speed ratio (etr) of the torque converter (2), and an input rotational speed (Ne) of the torque converter (2) (= engine rotational speed (step S21-3). The road surface gradient is calculated by using a wheel driving force to be calculated by this torque (TQtr).
