Abstract: A liner-sieve system for use with a litter box which employs litter of the clumping type. The system includes a cassette having a plurality of flexible liner sheets stacked over the litter box with an expandable or stretchable netting secured to a surface of each liner sheet disposed in a central area of the box. A releasable flap in the form of a slit is formed in each liner sheet beneath the netting. The liner sheets are fused together at peripheral edges which can be draped over the wall of the litter box, and the liner sheets are perforated adjacent the peripheral edges for separation of an uppermost liner sheet from the next lower liner sheet. Clumping litter disposed in the central area opens the flap to allow the unclumped litter to sift through the netting onto the next lower liner sheet. The clumped litter and feces is retained in the liner and netting material for convenient disposal.

Abstract: A method for ameliorating a cellular dysfunction of a tissue such as the cosmetic treatment of hair loss and stimulation of hair growth is disclosed. The method comprises administering substituted or unsubstituted 2,2,6,6-tetramethyl-1-piperdinyloxyl (TEMPO) to the affected tissue.

Abstract: A composition and method for ameliorating a cellular dysfunction of a tissue such as the cosmetic treatment of hair loss and stimulation of hair growth are disclosed. The method comprises administering a nitroso or nitrone spin trap such as N-t-butyl-.alpha.-phenylnitrone (PBN) to the affected tissue.

Abstract: A composition and method for ameliorating a cellular dysfunction of a tissue such as the cosmetic treatment of hair loss and stimulation of hair growth is disclosed. The method comprises administering 2,2-disubstituted-4,4-dimethyl-3-oxazolidinyloxy (DOXYL) to the affected tissue.

Abstract: A composition and method for ameliorating a cellular dysfunction of a tissue such as the cosmetic treatment of hair loss and stimulation of hair growth is disclosed. The method comprises administering substituted or unsubstituted 2,2,5,5-tetramethyl-1-pyrrolidinyloxyl (PROXYL) to the affected tissue.

Abstract: A composition and method for ameliorating a cellular dysfunction of a tissue such as the cosmetic treatment of hair loss and stimulation of hair growth are disclosed. The method comprises administering a spin label such as 2-(acetoxymercuri)-4,4,5,5-tetramethyl-2-imidazolin-1-yloxy-3-oxide, 3-carbamoyl-2,5-dihydro-2,2,5,5,-tetramethyl-1H-pyrrol-1-yloxy, or 3-(?ethoxycarbonyl!-oxycarbonyl)-2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol -1-yloxy to the affected tissue.
