Abstract: A pneumatic tire that can enhance durability and productivity of a carcass edge portion is disclosed. The pneumatic tire can include a tread portion, a side wall portion, and a bead portion and in which a carcass is installed at the bottom of the side wall portion and the tread portion, wherein the carcass is configured with a bottom carcass sheet and an upper carcass sheet, one end of the bottom carcass sheet having a termination point at a position that winds up a bead core of the bead portion in an outward direction, and one end of the upper carcass sheet having a termination point at an inner side surface of the bead portion.

Abstract: The present invention relates to a composition for controlling aging and/or extending lifespan. More specifically, the present invention relates to a composition containing dapsone as an effective component for controlling aging and/or extending lifespan, in which when applying the composition according to the present invention to an object, the effect of controlling aging or extending lifespan is excellent. Specifically, the treatment of dapsone (DDS) increases the lifespan of C. elegans not depending upon daf-16 and delays aging process, and reduces the activity of cytoplasmic dual oxidase 1 (Duox1) and mitochondria complex V protein. In addition, dapsone can maintain the low oxygen uptake rate in C. elegans thereby reducing ROS formation. In addition, ROS production by paraquat that is an inducing material of oxidative stress is reduced by treating dapsone and the sensitivity of paraquat is reduced.
