The present invention relates to fluorochemical polyurethane compounds, a method for their preparation, a method of application, and compositions comprising that fluorochemical polyurethane compound. Receptors that specifically bind to PR-5 proteins having a lectin-like \u03b2 barrel domain have been found to be homologous to mammalian adiponectin receptors, and such PR-5 proteins can act as functional homologues of adiponectin and control adiponectin response in mammals. A seatback is hinged to the seat cushion, with the seatback having a folded position and an unfolded position. Manual actuation of a tensioning mechanism that is coupled with the body member advances opposing first and second attachment members toward one another, moving the spring wing rail into an open position. One sidewall includes a setback area along the entire lower edge which has a height greater than the height of a sidewall of a prefabricated shower module.
