Abstract: Provided herein are piperidine dione compounds having the following structure: wherein R1, R2, R3, R4, L, V, X, a and m are as defined herein, compositions comprising an effective amount of a piperidine dione compound, and methods for treating or preventing an androgen receptor mediated disease.

Abstract: Pad conditioning brushes are described. In particular, pad conditioning brushes including a carrier layer and a plurality of abrasive particle-free brush bristles extending from the carrier layer are described. The carrier layer and the plurality of brush bristles form a unitary body. Such brushes may provide excellent performance compared to traditional conditioning disks.

Abstract: A filtration material comprising a blend of at least two types of fibers: (a) polypropylene fibers and (b) either acrylic or modacrylic fibers. In a preferred embodiment, the blend contains about 50 weight percent polypropylene fibers and about 50 weight percent modacrylic fibers. In another preferred embodiment, the blend contains about 50 weight percent polypropylene fibers and about 50 weight percent acrylic fibers. The fibers can be blended ranging from 90:10 to 10:90 polypropylene to acrylic or modacrylic. At least one type of fibers includes an extractable agent on the outer surfaces thereof. Performance of the blend is superior to the prior art filtration materials, especially at the preferred compositions.

Abstract: A filter material comprising a blend of at least three types of fibers: (a) polypropylene fibers (b) polymethaphenylene isophtalamide fibers and (c) fibers of a third type selected from the group of acrylic and modacrylic. In a preferred embodiment, the blend contains about ten weight percent polymethaphenylene isophtalamide fibers, about 50 weight percent polypropylene fibers and about 40 weight percent modacrylic fibers. Performance of the blend is superior to the prior art filtration materials, especially at the preferred compositions.
