24. A 68-year-old woman is evaluated for progressive dyspnea on exertion for the last 4 months and dry chronic cough for 1 year. She has a 15-pack/year history of smoking but quit 5 years ago. The patient complains of muscle aches and pains, with occasional night chills. She has lost 8 pounds in the last 2 weeks unintentionally. Vital signs are normal except for a respiratory rate of 22/min and 37.3 C (99.1 F). Cardiac examination is normal, and no jugular venous distension is observed. Reduced breath sounds are noted throughout the lungs with predominance at the lung apexes. Pulmonary function tests show total lung capacity is 60% of predicted. Residual lung volume is reduced. CXR and CT show lung fibrosis, predominantly in the upper lobes.  Further investigation reveals that the patient has worked on a crop farm all her life. Which of the following is the most likely diagnosis?

Answer one of the following prompts. You may not answer the same prompt twice.  You must have a thesis and evidence to support it. Remember to address all parts of the prompt.  1. Explain how Industrialization is related to colonization and imperialism. OR 2. Explain why so many revolutions occurred in Europe in 1848 and evaluate why they failed. OR 3. Describe how industrialization began in Great Britain. What circumstances made Britain unique; why did industrialization start there? OR 4. Was colonial rule a transforming, even a revolutionary, experience, or did it serve to preserve existing social and economic patterns? What evidence can you find to support both sides of this argument?

In Han Dynasty China, there is evidence of dissections of corpses. This is in the form of organ measurements in the Inner Canon of the Yellow Emperor, and later accounts from physicians suggesting that some vivisection was practiced, exclusively during surgery, to investigate damage.
