A method for facilitating the transfer of nucleic acids into cells comprising preparing a mixed lipid dispersion of a cationic lipid with a co-lipid in a suitable carrier solvent. The lipid has a structure which includes a lipophilic group derived from cholesterol, a linker bond, a spacer arm including from about 1 to about 20 carbon atoms in a branched or unbranched linear alkyl chain, and a cati...

BCRF1 proteins, and expression vectors for producing them, are provided for treating conditions associated with excessive production of IFN- gamma . Compositions of the invention containing BCRF1 proteins are useful in treating a variety of disorders, including allergy, psoriasis, tissue rejection, and MHC-linked autoimmune diseases.

A pilot-operated servo valve design for efficient mounting in a controlblock has at least three main-stream ports. An opening into a control sleeve for a first main-stream port is disposed opposite an end surface of a main control piston. The main control piston has a pressureequalizing surface disposed in a pressure-equalizing chamber, which is fluidically coupled by a pressure-equalizing duct in...

An article made from at least one network of high strength fibers and a thermoplastic polyurethane matrix material derived from an aliphatic didiisocyanate and a polyol. Preferably, the article is made from at least one prepreg element which includes at least two adjacent layers of the high strength fiber network in the thermoplastic polyurethane matrix material.

Disclosed is a process for obtaining polyester articles, including foamed articles, containing low levels of extractable branching agent. The process comprises: (1) forming a molten mixture comprising (i) a major amount of a first resin composition comprising polyester and from 0 up to about 1 wt. % of a compound capable of branching the polyester, and (ii) a minor amount of a second polyester res...

In the preparation of organopolysiloxane microemulsions, the components A) organopolysiloxane, B) emulsifier, C) water, optionally D) cosurfactant and optionally E) acid are combined and mixed in any desired sequence. Microemulsions form spontaneously without the input of energy in the form of heat or strong shear forces.

ACID WASH FOR BARRIER FILMS The process of the present invention teaches a novel method of cleansing a silane coated substrate of excess vinyl benzaldehyde. The basic process comprises the step of rinsing the silane coated substrate in acid, prior to exposing the silane coated film to the beverage. Alternatively, the silane coated substrate may be washed with water after the silane coated substrat...

The invention relates to a process for lacquering vehicle bodies, in which an aqueous lacquer is used as a stone-resistant intermediate coat and/or filler. The aqueous lacquer contains a binder consisting of a combination of a water-dilutable polyurethane resin, a water-dilutable polyester resin and an aminoplastic resin.

The invention relates to a stapler with a staple magazine (22) fitted on a bearing bracket (12) on the base (14) so as to pivot to a limited extent, and a cap section (34) pivotable through about 180 between a closed position and an open loading position and bearing an ejector (32) engaging in the staple magazine (22). According to the invention, the base (14) is bounded at the rear of the bearin...
