Here's what I found a while back when seeking info about tumor necrosis. 1) Necrosis in the tumor means that the cancer cells in that area are dead. The pathologic finding of necrosis suggests a fast-growing cancer. This often happens because the tumor runs out of blood supply in the central portion. Without a blood supply, the tumor cells cannot live.
Football cleats also come in the removable and molded variety. Molded cleats tend to be less expensive and are often required for youth play for safety reasons. Detachable football cleats are made of rubber, hard plastic or metal and come in a variety of lengths for use on different playing surfaces.
Artificial turf's stiff plastics and polymer surface is not as forgiving as natural grass, and when you try to pivot or make sharp lateral movements, it grabs your shoe; thus, short cleats, or studs, are best. Cleats measuring 1/2 an inch are called firm-ground cleats. Compared to the 1-inch, soft-ground cleats, the short cleats are less likely to get locked into â or tear up â artificial turf, and allow athletes better mobility and healthier knees.
