Abstract: Compositions and methods are provided for the treatment of diseases associated with mitogen activated protein kinase cascades. In particular, the mitogen-activated protein kinase p38-2, and polypeptide variants thereof that stimulate phosphorylation and activation of substrates such as ATF2, are provided. The polypeptides may be used, for example, to identify antibodies and other agents that inhibit or activate signal transduction via the p38-2 kinase cascade. Such polypeptides and agents may also be used for the treatment of diseases associated with mitogen-activated protein kinase cascades.

Abstract: Invert emulsion drilling system fluids comprising an oleaginous continuous phase and a non-oleaginous dispersed phase, the dispersed phase comprising organofunctional compound(s) effective to provide shale inhibition. The organofunctional compound(s) may be used either as a supplement to or as a substitute for metallic salts.

Abstract: An environmentally acceptable, thermally insulating annular fluid comprised of a liquid which is non-aqueous, non-corrosive, and thermally insulating, a clay gellant, and a clay dispersant. A preferred packer fluid includes an ester originated from a vegetable or animal oil as at least a major portion of the liquid phase.

Abstract: A unidirectional flow heart valve includes a passageway having an inlet side and an outlet side. A disk occluder is disposed within the passageway. The disk occluder has a closed position wherein the disk occluder occludes fluid flow through the passageway and an open position wherein the disk occluder permits fluid flow through the passageway. A fulcrum causes the disk occluder to pivot off center between the open and closed positions. An electromagnetic control mechanism forces the disk occluder to remain closed when energized until a predetermined net pressure is reached against the disk occluder. When the electromagnetic control mechanism is either selectively deenergized or the force on the occluder disk is greater than the holding force of the electromagnetic control mechanism, the disk occluder is released from the closed position to pivot on the fulcrum in response to fluid pressure.

Abstract: A drive system for artificial hearts and left-ventricular assist devices. The drive system includes one or more implantable pumps driven by external electromagnets. Each pump preferably includes an armature made of a permanent magnet material having a magnetic energy product of at least about 30.times.10.sup.6 Gauss Oersted, and coercivity of at least about 10 kOe.In one embodiment of the invention, a pair of pumps are provided, with each being coupled to a respective ventricle of an artificial heart. In a second embodiment, a pair of pumps is connected to a single left-ventricular assist device.Each pump is mounted to the pelvic bone in the vicinity of the iliac crest. Fluid communication between the pump and its associated ventricle or left-ventricular assist device is provided by a length of flexible tubing extending subcutaneously up from the pump. Means are provided to enable periodic reversal of internal system leakage, and to enable replenishment of fluid lost from the system.

Abstract: Novel compounds of formula (IID) ##STR1## wherein either both X and Y represent groups independently selected from amino and lower alkylamino, or one of X and Y represents a group selected from amino and lower alkylamino and the other of X and Y represents a hydrogen atom have been found to be active against rhinoviruses and other viruses. Processes for producing these compounds include reduction of flavanone derivatives or of flavenes. Alternatively, reductive cyclization of chalcones affords the compounds. These may also be prepared by condensation of o-(substituted methyl)phenols with styrene derivatives.Pharmaceutical formulations and methods for the administration of the compounds are described.

Abstract: A method for UV (ultraviolet) fluorescence counting of selected biological masses, such as egg masses, on foliage samples comprising the steps of: exposing a foliage sample having attached egg masses to UV radiation by a scanning beam; discriminating between the fluoresced light due to the masses and the fluoresced light due to other biological or foliage components; and counting the egg masses based upon the fluoresced light emitted by the egg masses. Also, an apparatus for UV fluorescence counting of egg masses on foliage samples is provided comprising a sample feed means having a test chamber; combined electro-optical sample scanner, fluorescent light divider, and detector; and an electronic signal discriminator and counter for selecting the divided fluorescent light signals emitted by egg masses from the emitted light of other foliage components, to thereby provide a count of the egg masses.
