[EX Q]: Context: An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Electromagnetic induction is the process of generating current with a magnetic field. It occurs when a magnetic field and electric conductor, such as a coil of wire, move relative to one another. A transformer may either increase or decrease voltage. You can see the basic components of an electric transformer in the Figure 1.1. Click image to the left or use the URL below. URL: The transformer in the diagram consists of two wire coils wrapped around an iron core. Each coil is part of a different circuit. When alternating current passes through coil P, it magnetizes the iron core. Because the current is alternating, the magnetic field of the iron core keeps reversing. This is where electromagnetic induction comes in. The changing magnetic field induces alternating current in coil S of the other circuit. Notice that coil P and coil S in the Figure 1.1 have the same number of turns of wire. In this case, the voltages of the primary and secondary currents are the same. Usually, the two coils of a transformer have different numbers of turns. In that case, the voltages of the two currents are different. When coil S has more turns than coil P, the voltage in the secondary current is greater than the voltage in the primary current (see Figure 1.2). This type of transformer is called a step-up transformer. Thats because it steps up, or increases, the voltage. When coil S has fewer turns of wire than coil P, the voltage in the secondary current is less than the voltage in the primary current (see Figure 1.3). This type of transformer is called a step-down transformer because it steps down, or decreases, the voltage. Q: Both step-up and step-down transformers are used in the electrical grid that carries electricity from a power plant to your home. Where in the grid do you think step-down transformers might be used? A: One place that step-down transformers are used is on the electric poles that supply current to homes. They reduce the voltage of the electric current before it enters home circuits.
Question: an electric transformer contains
[EX A]: an iron core.

[EX Q]: Context: The aim of this study was to elucidate the role of lysyl oxidase (LOX) and lysyl oxidase like (LOXL) 2 in pathologic wound healing after glaucoma surgery. We therefore investigated the expression of LOX and LOXL2 and evaluated the therapeutic potential of anti-LOX (GS-639556, formerly M64) and anti-LOXL2 (GS-607601, formerly AB0023) antibodies in a rabbit model of glaucoma trabeculectomy. Ocular expression of LOX and LOXL2 was investigated by immunohistologic staining at different time points after trabeculectomy. Treatment with GS-639556 or GS-607601 was initiated in rabbits immediately after trabeculectomy by giving both intracameral and subconjunctival injections. Thereafter, the antibodies were given twice a week subconjunctivally until day 30 after surgery (day of euthanization). Treatment outcome was studied by clinical investigation of the bleb and by immunohistochemical analysis of angiogenesis, inflammation, and collagen deposition. LOX and LOXL2 were both upregulated in Tenon's capsule and the conjunctiva after glaucoma surgery. Repeated administration of LOX- or LOXL2-targeting monoclonal antibodies increased bleb area and bleb survival. Analyses of immunohistologic stainings showed that both antibodies significantly decreased fibrosis, whereas the anti-LOXL2 antibody also significantly reduced blood vessel density and inflammation. Targeting LOXL2 with an inhibitory monoclonal antibody (GS-607601) reduced pathologic angiogenesis, inflammation, and fibrosis. These results suggest that LOXL2 could be an appealing target for treatment of scar formation after glaucoma surgery, and point to the potential therapeutic benefits of simtuzumab, a humanized monoclonal antibody derived from GS-607601.
Question: What is the drug target for Simtuzumab?
[EX A]: loxl2

[EX Q]: Context: The officials of a city unveil a new statue, only to find The Tramp sleeping on it. They shoo him away and he wanders the streets, destitute and homeless, and is soon tormented by two newsboys. He happens upon a beautiful Flower Girl (Virginia Cherrill), not realizing at first that she is blind, and buys a flower. Just when she is about to give him his change, a man gets into a nearby luxury car and is driven away, making her think that the Tramp has departed. The Tramp tiptoes away. That evening, the Tramp runs into a drunken Millionaire (Harry Myers) who is attempting suicide on the waterfront. (It is later mentioned that his wife has sent for her bags.) The Tramp eventually convinces The Millionaire he should live. He takes the Tramp back to his mansion and gives him a change of clothes. They go out for a night on the town, where the Tramp inadvertently causes much havoc. Early the next morning, they return to the mansion and encounter the Flower Girl en route to her vending spot. The Tramp asks The Millionaire for some money, which he uses to buy all the girl's flowers and then drives her home in the Millionaire's Rolls-Royce.After he leaves, the Flower Girl tells her Grandmother (Florence Lee) about her wealthy acquaintance. When the Tramp returns to the mansion, the Millionaire has sobered and does not remember him, so has the butler order him out. Later that day, the Millionaire meets the Tramp again while intoxicated, and invites him home for a lavish party. The next morning, having sobered again and planning to leave for a cruise, the Millionaire again has the Tramp tossed out.Returning to the Flower Girl's apartment, the Tramp spies her being attended by a doctor. Deciding to take a job to earn money for her, he becomes a street sweeper. Meanwhile, the Grandmother receives a notice that she and the girl will be evicted if they cannot pay their back rent by the next day, but hides it. The Tramp visits the girl on his lunch break, and sees a newspaper story about a Viennese doctor who has devised an operation that cures blindness. He then finds the eviction notice and reads it aloud at the girl's request. He reassures her that he will pay the rent. But he returns to work late and is fired.As he is walking away, a boxer persuades him to stage a fake fight, promising to split the $50 prize money. Just before the bout, however, the man receives a telegram warning him that the police are after him. He flees, leaving the Tramp a no-nonsense replacement opponent. Despite a valiant effort, the Tramp is knocked out.Some time later, he meets the drunken Millionaire who has just returned from Europe. The Millionaire takes him to the mansion and after he hears the girl's plight, gives the Tramp $1,000. Unbeknownst to the Millionaire and the Tramp, two burglars were hiding in the house when they entered. Upon hearing about the cash, they knock out the millionaire and take the rest of his money. The Tramp telephones for the police, but the robbers flee before they arrive, and the butler assumes he stole the money. The Millionaire cannot remember the Tramp or giving him the $1,000. The Tramp narrowly escapes and gives the money to the girl saying he will be going away for a while. Later, he is arrested in front of the newsboys who taunted him earlier, and jailed.Months later, the Tramp is released. Searching for the girl, he returns to her customary street corner but does not find her. With her sight restored, the girl has opened up a flourishing flower shop with her Grandmother. When a rich customer comes into the shop, the girl briefly wonders if he is her mysterious benefactor. But when he leaves with no acknowledgement, she realizes again she is wrong. While retrieving a flower from the gutter outside the shop, the Tramp is again tormented by the two newsboys. As he turns to leave, he finds himself staring at the girl
