PROBLEM: Context: Dabigatran is a direct thrombin inhibitor used to reduce the risk of stroke in patients with nonvalvular atrial fibrillation. For patients who present with an acute stroke despite dabigatran therapy, clinical data on the use of intravenous tissue plasminogen activator (IV-tPA) is limited. There is an anticipated increased risk of symptomatic intracranial hemorrhage (sICH) when using IV-tPA in patients on dabigatran therapy. In 2015, the humanized monoclonal antibody fragment idarucizumab was approved for rapid (minutes) reversal of anticoagulant effects of dabigatran. Dabigatran reversal with idarucizumab before administration of IV-tPA might reduce the risk of sICH. We report a case of a 69-year-old stroke patient on dabigatran for paroxysmal atrial fibrillation who presented with an initial National Institutes of Health Stroke Scale (NIHSS) of 12. There was no early evidence of ischemic stroke or hemorrhage on head computed tomography, and coagulation studies implied therapeutic dabigatran levels. After controlling blood pressure, dabigatran was reversed with idarucizumab, and IV-tPA was administrated beginning 197minutes after he was last seen at his baseline. Subsequent brain magnetic resonance imaging showed 2 punctate infarcts in the left temporal lobe and occipital lobe with no evidence of hemorrhage. The patient was discharged with an NIHSS of 1. Telephone follow-up 2 months later indicated that he was at his prestroke baseline, except for a complaint of worsened short-term memory. Idarucizumab reversal of dabigatran may reduce the risk of sICH and should be considered for acute stroke patients arriving in the IV-tPA time window. 
 Question: Which drug can be reversed with idarucizumab?

SOLUTION: dabigatran

PROBLEM: Context: An eastern cult (a parody of the Thuggee cult) is about to sacrifice a woman to the goddess Kaili. Just as she is about to be killed, the high priestess of the cult, Ahme, notices that she is not wearing the sacrificial ring. Ringo Starr, drummer of the Beatles, has and is wearing it; it was secretly sent to him by the victim in a fan letter. Determined to retrieve the ring and sacrifice the woman, the great Swami Clang, Ahme, and several cult members including Bhuta, leave for London. After several failed attempts to steal the ring, they confront the Beatles in an Indian restaurant. Ringo learns that if he does not return the ring soon, he will become the next sacrifice. Ringo then discovers that the ring is stuck on his finger. The Beatles go to a jeweller to remove the ring, but the tools he uses all break. They then go to a mad scientist, Foot, and his assistant Algernon. In a lab full of British-made equipment, they attempt to expand the ring's molecules so it can slide off Ringo's finger. But the machines only manage to remove all his other rings. Astonished that his equipment has no effect on the ring, Foot decides that he, too, must have it. While they bumble with trying to get a laser together, Ahme crashes the lab and holds the scientists at gunpoint while she lets the Beatles escape. Back home, Ahme tells the group that her sister's time has passed and she is now out of danger and Ringo is now the sacrificial victim. She prepares a special solution intended to shrink Ringo's finger so she can get the ring off. But then Clang and his henchmen crash the house, causing Ahme to drop the syringe on Paul's leg. While a shrunken Paul hides in an ashtray, the cult attack the other Beatles and pour red paint on Ringo (as part of the sacrifice). Foot and Algernon come in, shoots a warning shot with his Webley and scares the cult away, Ahme in tow. Paul unshrinks and John subsequently starts to swing a lamp at Foot who tries to shoot him, but his gun misfires. Blaming this on the fact that the gun is British made, Foot retreats. The boys are left to sort things out. The band flees to the Austrian Alps for refuge but both thugs and Foot follow in pursuit. The Beatles practice skiing, then participate in a game of curling. Foot and Algernon booby-trap one of the curling stones with a bomb; George sees the "fiendish thingy" and tells everyone to run. The bomb eventually goes off after a delay, creating a big hole in the ice from which a Channel swimmer (Mal Evans) emerges and asks directions to the White Cliffs of Dover. The boys ski down a slope fleeing from Clang, directed by Ahme, who then misdirects Clang to the take-off ramp for a Ski jumping contest. Clang is the winner, and is forced to the winners' platform to receive a gold medal. The group escapes back to England and they ask for "protection" from Scotland Yard; and get it in the form of a cowardly Inspector (Cargill). After being attacked while recording in the middle of Salisbury Plain surrounded by the British Army, they hide in "A Well Known Palace" (Buckingham Palace) until they are almost captured by Foot. While on a walk with the police, the group step into a small pub, where Clang is disguised as a barman. After being served beer, Ringo cannot pick his glass up from the table, so George tips it over, unknowingly opening a trapdoor to the cellar that Clang set up. Inside the cellar is a door with a broken knob, a broken ladder and a tiger. They go summon the Inspector who tells them to sing the "Ode to Joy" from Beethoven's 9th Symphony to the tiger in order to tame it; everyone inside and outside the pub joins in. The Beatles put out in the press that they're going to the Bahamas to throw the cult off their

PROBLEM: Context: The man in Figure 16.14 is using a ramp to move a heavy dryer up to the back of a truck. The highway in the figure switches back and forth so it climbs up the steep hillside. Both the ramp and the highway are examples of inclined planes. An inclined plane is a simple machine consisting of a sloping surface that connects lower and higher elevations. The sloping surface of the inclined plane supports part of the weight of the object as it moves up the slope. As a result, it takes less force to move the object uphill. The trade-off is that the object must be moved over a greater distance than if it were moved straight up to the higher elevation. On the other hand, the output force is greater than the input force because it is applied over a shorter distance. Like other simple machines, the ideal mechanical advantage of an inclined plane is given by: Ideal Mechanical Advantage = Input distance Output distance For an inclined plane, the input distance is the length of the sloping surface, and the output distance is the maximum height of the inclined plane. This was illustrated in Figure 16.12. Because the sloping surface is always greater than the height of the inclined plane, the ideal mechanical advantage of an inclined plane is always greater than 1. An inclined plane with a longer sloping surface relative to its height has a gentler slope. An inclined plane with a gentler slope has a greater mechanical advantage and requires less input force to move an object to a higher elevation. Two simple machines that are based on the inclined plane are the wedge and the screw. Both increase the force used to move an object because the input force is applied over a greater distance than the output force. Imagine trying to slice a tomato with a fork or spoon instead of a knife, like the one in Figure 16.15. The knife makes the job a lot easier because of the wedge shape of the blade. A wedge is a simple machine that consists of two inclined planes. But unlike one inclined plane, a wedge works only when it moves. It has a thin end and thick end, and the thin end is forced into an object to cut or split it. The chisel in Figure 16.15 is another example of a wedge. The input force is applied to the thick end of a wedge, and it acts over the length of the wedge. The output force pushes against the object on both sides of the wedge, so the output distance is the thickness of the wedge. Therefore, the ideal mechanical advantage of a wedge can be calculated as: Ideal Mechanical Advantage = Length of wedge Maximum thickness of wedge The length of a wedge is always greater than its maximum thickness. As a result, the ideal mechanical advantage of a wedge is always greater than 1. The spiral staircase in Figure 16.16 also contains an inclined plane. Do you see it? The stairs that wrap around the inside of the walls make up the inclined plane. The spiral staircase is an example of a screw. A screw is a simple machine that consists of an inclined plane wrapped around a cylinder or cone. No doubt you are familiar with screws like the wood screw in Figure 16.16. The screw top of the container in the figure is another example. Screws move objects to a higher elevation (or greater depth) by increasing the force applied. When you use a wood screw, you apply force to turn the inclined plane. The output force pushes the screw into the wood. It acts along the length of the cylinder around which the inclined plane is wrapped. Therefore, the ideal mechanical advantage of a screw is calculated as: Ideal Mechanical Advantage = Length of inclined plane Length of screw The length of the inclined plane is always greater than the length of the screw. As a result, the mechanical advantage of a screw is always greater than 1. Look at the collection of screws and bolts in Figure 16.17. In some of them, the turns (or threads) of the inclined plane are closer together. The closer together the threads are, the longer the inclined plane is relative to the length of the screw or bolt, so
