Abstract: A frame for a bicycle is disclosed. The bicycle also has a drivetrain, and a plurality of wheels. The frame has a main frame portion, a rear frame portion, a pair of shock absorber mounts, and a pair of linkages. The first linkage is pivotably connected to the rear frame portion and pivotably connected to the main frame portion. The second linkage is also pivotably connected to the rear frame portion and to the main frame portion and further provides a mounting for a drivetrain component such as an idler or bottom bracket. Both linkages also rotate in a counter direction relative to the rotation of the rear frame portion.

Abstract: The present invention provides a pharmaceutical composition comprising at least one pharmaceutically acceptable bismuth-containing compound, at least one pharmaceutically acceptable non-clay-derived suspending agent, water, and a stabilizing means for reducing viscosity change upon storage of the composition. The suspension exhibits reduced change in viscosity by comparison with an otherwise similar suspension excepting the stabilizing means. Such compositions are useful in the prevention and treatment of gastrointestinal diseases and/or disorders.

Abstract: Compounds, compositions and methods are disclosed useful for enhancing penetration of a pharmacologically active substances across skin or tissue membranes. Compounds for use in such compositions and methods are highly water-soluble N-substituted polyalkylene oxide derivatives of cyclic amides. A compound of the invention has the structural formula: wherein m is an integer from 2 to about 6, n is an integer from 1 to about 8, and R is hydrogen, trimethylsilyl or lower alkyl.
