Figure 3: Vasodilation produced by the direct effects of caffeine on the VSMC. Caffeine inhibits the voltage-dependent Ca2+ channels and the entrance of calcium to the cytoplasm. In addition, it inhibits the IP3 receptor and increases the ânon-contractile Ca2+.

If you burn your hand, plunge it into the ice water and keep it there for at least 2 minutes. This will minimize the burn. Preheat a large non-stick pan over medium heat. Sprinkle just enough of the 2 cups of sugar into the pan to lightly cover the bottom. Do not stir. As the sugar melts, sprinkle more sugar over the hot spots. This keeps the temperature even, and prevents scorching. Continue with this method until about half of the sugar has been incorporated. Stir gently with a wooden spoon to melt all the sugar into a smooth caramel. Add the remaining sugar, about 1/4 at a time, and continue to stir to keep the caramel smooth.
