...eight teaspoons of sugar dissolved in a liter of water then administered gradually - at a cost of literally pennies per child. The Mechanism When ORS reaches the small intestine, the sodium-glucose co-transport pathway moves sugar from the hollow part of the intestine (lumen) to its lining (epithelium) through the villi. Sugar makes the salt absorption more efficient, and salt promotes water's absorption into the capillary-rich intestinal walls. Intestinal Villi Tiny finger-like projections in the small intestine's lining absorb fluid and nutrients into the blood through the capillary-rich layer beneath the epithelium. From there...
...surgeons first tried using the excimer laser to correct vision in a procedure called photorefractive keratectomy. They scaled off the cornea's outermost protective layer, or epithelium. Then they vaporized some of the underlying tissue with the laser, forcing the cornea to flatten or steepen, depending on the correction. Although the epithelium always grew back, the cornea retained its new shape. It was a big improvement over radial keratotomy, although the healing of the epithelium remained painful...

Emasculated as he appears on the surface, he faces death with remarkable nonchalance; he is there in the pinch. Maybe this characterization conveys something mystical and beautiful to you. If it does, be sure...
