PROBLEM: Context: The muscular system consists of all the muscles in the body. This is the body system that allows us to move. You also depend on many muscles to keep you alive. Your heart, which is mostly muscle, pumps blood around your body. Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot dothey are able to get shorter. Shortening of muscle fibers is called contraction. Muscle fibers can contract because they are made of proteins, called actin and myosin, that form long filaments (or fibers). When muscles contract, these protein filaments slide or glide past one another, shortening the length of the cell. When your muscles relax, the length extends back to the previous position. Nearly all movement in the body is the result of muscle contraction. You can control some muscle movements. However, certain muscle movements happen without you thinking about them. Muscles that are under your conscious control are called voluntary muscles. Muscles that are not under your conscious control are called involuntary muscles. Muscle tissue is one of the four types of tissue found in animals. There are three different types of muscle in the body ( Figure 1.1): 1. Skeletal muscle is made up of voluntary muscles, usually attached to the skeleton. Skeletal muscles move the body. They can also contract involuntarily by reflexes. For example, you can choose to move your arm, but your arm would move automatically if you were to burn your finger on a stove top. This voluntary contraction begins with a thought process. A signal from your brain tells your muscles to contract or relax. Quickly contract and relax the muscles in your fingers a few times. Think about how quickly these signals must travel throughout your body to make this happen. 2. Smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. These muscles push materials like food or blood through organs. Unlike skeletal muscle, smooth muscle can never be under your control. 3. Cardiac muscle is also an involuntary muscle, found only in the heart. The cardiac muscle fibers all contract together, generating enough force to push blood throughout the body. What would happen if this muscle was under conscious or voluntary control? There are three types of muscles in the body: cardiac, skeletal, and smooth. 
 Question: what muscle pushes food through your intestines?

SOLUTION: smooth muscle

PROBLEM: Context: Playing in their second game of the season, the Cincinnati Bengals had a lot of things go wrong. Playing Ohio state rivals Cleveland Browns, the defense looked the exact opposite as they did in week one. Browns quarterback Derek Anderson started and threw for 328 yards and five touchdowns. It was only the third time in NFL history that two quarterbacks had thrown at least five touchdown passes in the same game. Jamal Lewis had 215 yards rushing with one touchdown and the Browns had two receivers with over 100 yards, Braylon Edwards and Kellen Winslow. The Bengals offense tried their best to keep the team in the game, however, as Carson Palmer threw for 6 TD's and Chad Johnson caught for 209 yards. The game started out slowly in the first quarter but the second quarter saw a combined 35 points scored. It was close in the end, when the Bengals started a drive with under one minute left. They managed to get the ball to the 50-yard line when Carson Palmer was intercepted by Leigh Bodden on an intended pass for Chad Johnson. This game ended up being the eighth highest scoring game in NFL history, but not the highest scoring game between these two teams. In 2004, the Bengals beat the Browns 58-48 for the second-most combined points. The Redskins (72) and Giants (41) combined for 113 points in 1966 for the most.

PROBLEM: Context: Vanoxerine has been in clinical trials for Parkinsonism, depression and cocaine addiction but lacked efficacy. Although a potent blocker of hERG, it produced no serious adverse events. We attributed the unexpected result to offsetting Multiple Ion Channel Effects (MICE). Vanoxerine's effects were strongly frequency-dependent and we repositioned it for treatment of atrial fibrillation and flutter. Vanoxerine terminated AF/AFL in an animal model and a dose-ranging clinical trial. Reversion to normal rhythm was associated with QT prolongation yet absent proarrhythmia markers for Torsade de Pointes (TdP). To understand the QT/TdP discordance, we used quantitative profiling and compared vanoxerine with dofetilide, a selective hERG-blocking torsadogen used for intractable AF, verapamil, a non-torsadogenic MICE comparator and bepridil, a torsadogenic MICE comparator. At clinically relevant concentrations, verapamil blocked hCav1.2 and hERG, as did vanoxerine and bepridil both of which also blocked hNav1.5. In acute experiments and simulations, dofetilide produced early after depolarizations (EADs) and arrhythmias, whereas verapamil, vanoxerine and bepridil produced no proarrhythmia markers. Of the MICE drugs only bepridil inhibited hERG trafficking following overnight exposure. The results are consistent with the emphasis on MICE of the CiPA assay. Additionally we propose that trafficking inhibition of hERG be added to CiPA. 
 Question: What alternate indication has Vanoxerine been repositioned for?

SOLUTION:
atrial fibrillation and flutter
