Q: Context: In a New York City residence, Pierre Delacroix (Damon Wayans) rises to begin his daily routine. Brushing his teeth, he gives us by voice over a definition of satire. He tells us that with the rise of the Internet, video and interactive games, his field as a television writer has seen a drop in popularity. Meanwhile, in a dilapidated building, squatter Womack (Tommy Davidson) wakes up his friend Manray (Savion Glover) for a day of work. This consists of travelling to the CNS (Continental Network System) building where Delacroix works, and Manray tap dancing to entertain the workers. They then collect money from the workers. The men see Delacroix walk by, and ask him for monetary help in the form of work of some kind.Delacroix walks into a staff meeting late and is immediately castigated by his boss, Thomas Dunwitty (Michael Rapaport). Dunwitty informs the staff that CNS has poor ratings. He says he wants them to write funnier material, and ends the meeting. In the privacy of his office, Dunwitty tells Delacroix that the material Delacroix's been writing for him seems like it's about white people with black faces. Dunwitty asserts that Delacroix is an "oreo" with his Harvard education, because he won't write a "n----r show."The next day, Delacroix and his assistant Sloan Hopkins (Jada Pinkett Smith) talk. They've decided that Manray is the solution to his problem. Delacroix plans to write a show that will be so "offensive and racist," it will prove his point that the network only wants to see black buffoons on the air. Delacroix simply hopes to be fired, so he can be let go of his contract with CNS. Manray and Womack ask at the receptionist's desk for a "Delapoint" and the men working there tell them to step outside. However, Sloan steps into the lobby, sees what's happening, and escorts Manray and Womack to Delacroix's office. Delacroix explains to them that he has an idea for a television pilot, and they can make money with it. His main request is that Manray changes his name to Mantan, in an apparent homage to black character actor Mantan Moreland.On Sloan's walk home, she runs into her big brother Big Blak Afrika F/K/A Julius (Yasiin Bey). In Sloan's apartment, Julius and Sloan argue about his values, and he tells her to introduce him and his political hip-hop crew, the Mau Maus, to Delacroix.Delacroix has another meeting with Dunwitty. Delacroix proposes that the network start a variety show called "Mantan: The New Millenium Minstrel Show." Delacroix says that new faces are needed for the show, and has Sloan bring in Manray and Womack. The two men, respectively renamed "Mantan" and "Sleep'n Eat," will exhibit a range of stereotypical traits, Delacroix explains. Sloan is opposed to the proceedings, and suggests that there will be protest of the show they are planning. To seal the package, Manray dances atop a table in front of Dunwitty -- who immediately leaves to try to sell the show's concept to his executive bosses.Delacroix, Sloan and another woman hold auditions for the show. The first group of people (The Roots) audition to be the show's house band, The Alabama Porch Monkeys. After they perform, a dancer, a vulgar man shouting "I be smackin' my hoes," and a didgeridoo player all audition. The next hopeful is Honeycutt (Thomas Jefferson Byrd), an actor who bungles Shakespearean quotes and proclaims "N----s is a beautiful thing." Sloan's brother's group, the Mau Maus then do a fiery, confrontational performance; Pierre states via voice over that there is no place for them in his plan.Delacroix looks over a revised script for the show and confronts Dunwitty and his co-writer, Jukka about their alterations to it that even he finds racially offensive. Delacroix says that he won't be responsible for their changes, which Dunwitty says are to make the show funnier. Dunwitty says he knows black people better than Delacroix does, telling him, "Look

Q: Context: It is unanimously accepted that there is an unmet need for pain medications that are both effective and safe. Unfortunately, no really novel analgesics have been approved over the past three decades. In view of both experimental and clinical evidence of a major role for nerve growth factor (NGF) in the generation and maintenance of a wide range of pain states, drug discovery efforts focusing on the development of anti-NGF agents have aroused particular interest. Several humanized anti-NGF monoclonal antibodies (mAbs) have entered clinical trials as potential analgesics. In this respect, tanezumab is at an advanced stage of clinical development while fulranumab, fasinumab and ABT-110, previously known as PG110, are in early phases of clinical development. This Current Opinion article aims at describing the rationale for targeting NGF for pain, reviewing the analgesic efficacy and safety of anti-NGF agents based on data from fully published studies, conference abstracts, and the US Food and Drug Administration (FDA) website, and discussing the possible future of these agents in managing chronic pain. Anti-NGF mAbs produced significant pain relief and functional improvement in patients with osteoarthritis of the knee and/or hip. Conversely, studies in non-specific lower back pain generated mixed results; overall, this condition appeared to be less responsive to anti-NGF agents than osteoarthritis. Finally, there was no conclusive evidence of the effectiveness of anti-NGF mAbs in some types of chronic visceral or neuropathic pain. Furthermore, these studies raised safety concerns about anti-NGF mAbs. As a class, these drugs may cause or worsen peripheral neuropathies. But the most problematic issue-which prompted the FDA to place studies of these compounds on clinical hold in 2010-was rapid joint destruction leading to joint replacement surgery. The aetiologies of these side effects have been much debated and their pathophysiology is poorly understood. After an Arthritis Advisory Committee meeting held in March 2012, pharmaceutical companies negotiated with the FDA on the conditions for restarting clinical studies. Although the FDA lifted its clinical hold, there remain many unresolved issues about the long-term efficacy and safety of anti-NGF mAbs. While acknowledging that the future of these drugs is unforeseeable, it appears that they may not be the safe and effective painkillers that have been awaited for decades. 
 Question: What is the target of tanezumab?

Q: Context: Both you and the speck of dust consist of atoms of matter. So does the ground beneath your feet. In fact, everything you can see and touch is made of matter. The only things that arent matter are forms of energy, such as light and sound. Although forms of energy are not matter, the air and other substances they travel through are. So what is matter? Matter is defined as anything that has mass and volume. Mass is the amount of matter in a substance or object. Mass is commonly measured with a balance. A simple mechanical balance is shown in Figure 3.1. It allows an object to be matched with other objects of known mass. SI units for mass are the kilogram, but for smaller masses grams are often used instead. The more matter an object contains, generally the more it weighs. However, weight is not the same thing as mass. Weight is a measure of the force of gravity pulling on an object. It is measured with a scale, like the kitchen- scale in Figure 3.2. The scale detects how forcefully objects in the pan are being pulled downward by the force of gravity. The SI unit for weight is the newton (N). The common English unit is the pound (lb). With Earths gravity, a mass of 1 kg has a weight of 9.8 N (2.2 lb). Problem Solving Problem: At Earths gravity, what is the weight in newtons of an object with a mass of 10 kg? Solution: At Earths gravity, 1 kg has a weight of 9.8 N. Therefore, 10 kg has a weight of (10 9.8 N) = 98 N. You Try It! Problem: If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force, so mass and weight are closely related. However, the weight of an object can change if the force of gravity changes, even while the mass of the object remains constant. Look at the photo of astronaut Edwin E. Aldrin Jr taken by fellow astronaut Neil Armstrong, the first human to walk on the moon, in Figure 3.3. An astronaut weighed less on the moon than he did on Earth because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. The amount of space matter takes up is its volume. How the volume of matter is measured depends on its state. The volume of liquids is measured with measuring containers. In the kitchen, liquid volume is usually measured with measuring cups or spoons. In the lab, liquid volume is measured with containers such as graduated cylinders. Units in the metric system for liquid volume include liters (L) and milliliters (mL). The volume of gases depends on the volume of their container. Thats because gases expand to fill whatever space is available to them. For example, as you drink water from a bottle, air rushes in to take the place of the water. An "empty" liter bottle actually holds a liter of air. How could you find the volume of air in an "empty" room? The volume of regularly shaped solids can be calculated from their dimensions. For example, the volume of a rectangular solid is the product of its length, width, and height (l w h). For solids that have irregular shapes, the displacement method is used to measure volume. You can see how it works in Figure 3.4 and in the video below. The SI unit for solid volumes is cubic meters (m3 ). However, cubic centimeters (cm3 ) are often used for smaller volume measurements. Matter has many properties. Some are physical properties. Physical properties of matter are properties that can be measured or observed without matter changing to a different substance. For example, whether a given substance normally exists as a solid, liquid, or gas is a physical property. Consider water. It is a liquid at room temperature, but if it freezes and
