摘要:
The invention features devices and methods for treatment of pain. The drug delivery device is a drug delivery system adapted for whole implantation in a subject and to provide pain relief by delivery of fentanyl or a fentanyl congener (e.g., sufentanil) over a protracted period of time (e.g., at least 3 days or more than 3 days). The device comprises a housing defining a reservoir that contains a drug formulation, a pump operatively connected to the housing so as to facilitate movement of drug out of the reservoir and out of the device, and a thermal expansion element which defines a flow pathway comprising a thermal expansion channel to accommodate thermal expansion of formulation in the reservoir. The device can further comprise a valve positioned within the flow pathway so as to prevent movement of drug out of the reservoir prior to use.

The invention features a plug for use with a drug delivery device, wherein the plug defines an expansion control channel, which accommodates thermal expansion of a formulation in a reservoir of a drug delivery device, and an exit channel. In one embodiment, the plug comprises an inner plug member and an outer plug member, which members define an expansion control channel to facilitate release of entrapped air and to accommodate thermal expansion of formulation from the sealed drug reservoir. The plug further defines an exit channel, and may optionally further comprise a frit positioned within the flow pathway just prior to the delivery outlet, or both.

A hand-held dispensing applicator comprising a source of fluid, a frangible applicator tip attached to the fluid source, and an absorbent member attached to the frangible applicator tip. The applicator may be applicable for a medical purpose. When the frangible applicator tip is broken, the fluid flows from the source to the absorbent member, spread on a surface. The frangible applicator tip may comprise a support element permanently connected to the fluid source, a relatively rigid tongue element, and a frangible region there between. The tongue element may comprise ribs for reinforcing the tongue element. The applicator tip may comprise a semi-permeable or non-permeable cover to control the speed and direction of the dispersion of the fluid.

A dentifrice composition containing minor amounts of relatively small particle size high cleaning abrasives, without oral care actives. The dentifrice may be encapsulated and optionally, positioned on the head of a toothbrush. Use of the dentifrice provides a small amount of high cleaning abrasive to the teeth, and has stain removal efficacy. In one aspect, a dentifrice composition comprising an orally acceptable carrier and 1 to 10 wt % abrasive, such that the total amount of abrasive delivered per application is 2 mg to 8 mg, the abrasive having a weight mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, and wherein the composition does not contain an oral care active.
摘要:
The present invention comprises a new class of compounds useful for the modulation of Beta-secretase enzyme activity and for the treatment of Beta-secretase mediated diseases, including Alzheimer's disease (AD) and other related conditions. In one embodiment, the compounds have a general Formula I wherein A1, A2, A3, A4, A5, A6, R2, R7, X and Y of Formula I are defined herein. The invention also includes use of these compounds in pharmaceutical compositions for treatment, prophylactic or therapeutic, of disorders and conditions related to the activity of beta-secretase protein. Such disorders include, for example, Alzheimer's Disease, cognitive deficits, cognitive impairment, schizophrenia and other central nervous system conditions related to and/or caused by the formation and/or deposition of plaque on the brain. The invention also comprises further embodiments of Formula I, intermediates and processes useful for the preparation of compounds of Formula I.
摘要:
A process of preparing a polymer modified asphalt (PMA) comprising mixing a predetermined amount of a polymer-asphalt master batch with a predetermined amount of an asphalt-cross linking agent blend. The polymer-asphalt master batch comprises at least one polymer and a first asphalt. The asphalt-cross linking agent blend comprises a second asphalt and at least one cross linking agent. A predetermined amount of the polymer-asphalt master batch is blended with a predetermined amount of the asphalt-cross linking agent blend to form a PMA blend. Mixing of the PMA blend is performed without substantial delay following blending of the polymer-asphalt master batch with the asphalt-cross linking agent blend.
摘要:
A hand-held dispensing applicator comprising a source of fluid, a frangible applicator tip attached to the fluid source, and an absorbent member attached to the frangible applicator tip. When the frangible applicator tip is broken, fluid flows from the source to the absorbent member, whereby the fluid is applied and spread on a surface. Preferably, the frangible applicator tip comprises a support element permanently connected to the fluid source, a relatively rigid tongue element extending outwardly of the support element, and a frangible region therebetween. Preferably, the tongue element comprises ribs for reinforcing the tongue element to resist unintentional breaking of the frangible region. More preferably, the applicator tip comprises a semi-permeable or non-permeable cover disposed around the frangible region to control the speed and direction of the dispersion of the fluid in the absorbent member. Adaptive embodiments allow the generation of designs applicable to a particular medical purpose.

Powder feed cylinder assemblies and powder feeders are provided. A powder feed cylinder assembly includes a cylinder, a bit, and bushings. The cylinder has a main passage, a first feed channel, and a second feed channel, each feed channel at two axial locations between the cylinder's two ends. The bit extends through the main passage and has an outer surface including a helical channel formed thereon. A center bushing is disposed in the main passage between the two axial locations and has a first axially-extending passage through which the bit extends. The first end bushing is disposed in the main passage on one side of the center bushing and has a second axially-extending passage through which the bit extends. The second end bushing is disposed in the cylinder on the other side of the center bushing and has a third axially-extending passage through which the bit extends.
