Sew a seam 7 inches from the folded edge to make a tube. Stitch twill tape in place. Thread elastic through the towel's existing hem: Snip one small slit in the towel's hem. Flip tube over and repeat, making a second slit. Tie a large knot at one end of elastic; attach safety pin to other end. Slide safety pin through 1 slit, and ease through hem and out other slit. Tie elastic ends to gather.
Glucagon causes the liver to release stores of glucose from hepatic polymers called glycogen, it also signals the liver to start a process called gluconeogenesis, in which glucose is produced from amino-acids after hepatic glycogen stores are depleted.
Glucagon secretion increases when blood sugar levels are diminished, countering insulin's effects upon glucose and fat metabolism. One might expect that glucagon would have a negative paracrine action on-cells, but that is NOT the case.
