Abstract: In accordance with the present invention, it has been discovered that PPAR&ggr; is expressed consistently in tissues associated with each of a variety of disease states which result from neoplastic cell proliferation. It has further been discovered that maximal activation of PPAR&ggr; with exogenous ligand promotes terminal differentiation of primary cells which are otherwise subject to neoplastic cell proliferation. In accordance with another aspect of the invention, it has been discovered that RXR-specific ligands are also potent agents for induction of differentiation of cells expressing the PPAR&ggr;/RXR&agr; heterodimer, and that simultaneous treatment of cells subject to neoplastic cell proliferation with a PPAR&ggr;-selective ligand, in combination with an RXR-specific ligand, results in an additive stimulation of differentiation.

Abstract: In accordance with the present invention, it has been discovered that retinoic acid receptor (RAR) antagonists are capable of modulating processes mediated by other members of the steroid/thyroid hormone receptor superfamily, including permissive receptors such as PPARs (e.g., PPAR&agr;, PPAR&dgr; and PPAR&ggr;). Indeed, it has been discovered that RAR antagonists, in combination with agonists for members of the steroid/thyroid hormone receptor superfamily, are capable of inducing and/or enhancing processes mediated by such members.

Abstract: In accordance with the present invention, it has been discovered that histone deacetylase associates with hormone receptor complexes and contributes to the repression thereof. It has further been discovered that exposure of a repressed system to histone deacetylase inhibitors relieves this repression. Thus, histone deacetylase inhibitors have been found to be useful for the activation of genes responsive to hormone receptors. In accordance with another aspect of the invention, formulations useful for modulation of hormone-mediated processes have been developed. In addition, assays have been developed for the identification of compounds useful to modulate the above-described processes.

The device comprises oxygen and air ducts, means for adjusting the composition, temperature, humidity, and other parameters of the gas mixture, a patient junction, and pressure adjusting valve means coupled to the junction shunting the gas flow in the junction in such a way that the gas pressure is positive both during expiration and inspiration.The respiration demand of the patient is sensed by a means responsive to pressure drops which controls a starting signal generator and a beat generator. The beat generator controls the valve means. The device can be adjusted to controlled respiration, controlled assisted respiration, inspected and assisted respiration, and continuous positive airway pressure modes, whereby it can be adapted to various respiratory diseases.

Abstract: Pharmaceutical compositions for sustained release of pharmaceutical compounds comprising a reaction product of a water soluble salt of a pharmaceutically active compound containing a primary, secondary or tertiary amino group, and an alkali or ammonium salt of a synthetic copolymer containing an acid group, and selected from the group consisting of methacrylic acid/methacrylic acid methyl ester, methacrylic acid/acrylic acid methyl ester and methacrylic acid/acrylic acid methyl ester/methacrylic acid methyl ester copolymers and a pharmaceutically acceptable excipient.

Abstract: A configuration for a sailboat mainsail comprises a rotating wind-mill like sail structure mounted on a rotating pedestal base. The wind driven rotating sail delivers power to the sailboat propeller through a flexible driveshaft and transmission and thus provides an ability to sail a particular desired course direction irrespective of the direction from which the wind is blowing.

Abstract: A split axle drive mechanism for a part-time four-wheel drive vehicle comprises an automotive type differential which has an input to the differential case and a pair of outputs from the respective side gears. One output is directly connected to its associated side gear so that the associated side gear is always drive connected to one selectively driven vehicle wheel. The other output includes a clutch which is disengaged in the two wheel drive mode (selected at the transfer case) so that the other selectively driven vehicle wheel does not back drive the other side gear. This reduces wear and power consumption in the two wheel drive mode.

Abstract: A transmission having a gravity feed and centrifugal pressure lubricating system. Rotating drive and output gearing throws oil to a primary collector for gravity feed down in a first passage in the housing to a through-bore in the output shaft and for feed upward in a second passage to a blind bore in the input shaft. Rotating high-speed gearing throws oil to a secondary collector for gravity feed in a second passage to the blind bore and then to the through-bore. A plastic disk, having a central aperture smaller than the shaft bores, is fixed and sealed in a chamber between each passage and each bore end. A disk resiliently engages a plastic ferrule in each open bore end to seal the disk to the shaft end to permit gravity flow of oil through the central aperture into the bores and to retain an annular body of oil in the bores during shaft rotation and to centrifuge the oil through radial ports to lubricate the drive gear bearings.

Abstract: A transmission having four forward gearsets and reverse gearing on one side of the forward gearsets. First and second shift members are mounted on the other side of the forward gearing for axial shifting movement to selectively engage the forward gearsets. A shift shaft having a shift lever is mounted transversely of the forward gearsets for axial selecting movement and rotary shifting movement. A reverse shift member is centrally pivotally mounted on the shift shaft, engages a guide to prevent axial movement, and has one end adjacent the other shift members and the other end shifting the reverse gearing.

Abstract: An improved construction for a lamp cap suitable for interconnecting the elongated constricted neck of a halogen lamp to an electrode-bearing lamp holder is described. A hollow elongated deformable insert is coaxially positioned within a conventional cover disc of the lamp cap. The interior dimension of the insert is chosen to effect a secure frictional engagement with at least 30% of the length of the constricted lamp neck, and is permanently or removably affixed to the surrounding cover disc. The lamp holder may then be affixed to the composite lamp cap to complete the assembly.
