Assume that two individuals (A and B) develop the same type of cancer. Both individuals are given the best treatment found to be effective against cancer. Individual A responds well to treatment, while individual B does not. Using what you have learned, provide a specific type of cancer and an explanation for why there was a difference in response to treatment

Expert Solution

first of all we have to know about the cancer, i.e, uncontrolled proliferation of cells thet arise from virtually any cell type in the body. Cancer is a type of tumour( neoplasia means new growth) that usually grows rapidly but not always some tumour are slow grows. The term cancer refers to a malignant tumour and not a benign tumour. Malignant tumour grows rapidly. Malignant cancer are very dangerous. benign are not. there are many type of cancer breast cancer in female,prostrate cancer in male,lungs cancer, pancreatic cancer, bladder cancer etc.Cancer are treated some therapies chemotherapy,radiotherapy etc.

Acoording to the question ,there are two individuals A and B develop the same type of cancer. Both individuals are given the best treatment found to be effective against cancer. Individuals A responds well to treatment, while individuals B does not. There was a difference in response to treatment because of their immune system.Traditionally we are treated cancer by attacking it with chemotherapy and radiation or by removing it with surgery but there's a new way instead of attacking cancer directly. We can now train the immune system to attack it. This new treatment is called immunotherapy. Immunotherapy uses the body's immune system to fight cancer. There are three types of immunotherapy used to treat cancer; nonspecific immune stimulation, t-cell transfer therapy and immune checkpoint inhibitors.

Immune system such as T-cells and APC's,they are defend and protect the body. APC's petrol the body looking for cancer and other diseases. Tcells are the soldiers of the immune system.when an APC finds something suspicious,an APC sends a specific signal back to a Tcell then T cells are to multiply an attack the suspicious cells. But if T cells dont stop,they can damage healthy cells.A safety switch,called a checkpint prevents this. because cancer is so complex,T cells are switched off before their work is done.but with checkpoint inhibitor drugs the most common type of immunotherapy, we can prevent T cell from being switched off. this allows to do their job.beacause immunotherapy targets the immune system and not cancer.

According to our immune system body will fight our cancer.

1. Consider two individuals. Both earn the same amount and choose to save the same amount. However, the first agent is more risk averse than the second. i) Do you expect the saving portfolios to be different for the two agents? Which of the two is more likely to hold stocks? Now, assume that the second individual is actually much wealthier than the first. ii) Do you expect the two agents to rely on the same type of financial intermediaries?...

A&B (two individuals) wants to organize an entity to combine their two businesses. Assume the business will average $1 million of taxable income from the combined businesses. What entity would you advise your client to form? Please include in your discussion a compare and contrast of the different forms of business regimes including a discussion of a corporation, an S corporation, partnership and a limited liability company.

Person A and B both have the same income, and there are only two goods in the market: good X has the price of $6, good Y has the price of $4. Considering A and B may have different bundles for purchasing good X and Y, but they are on the same budget line with the same MRT and MRS, will their consumer surplus always be the same? or does it depend on the bundles?

Suppose there are two types of workers in the economy, A and B. Assume that type A workers are, on average, more productive than type B workers (for instance, type A workers might have access to better schools than type B workers). Explain how it could be the case that some firms choose not to hire type B workers, even if: (a) qualified type B workers to apply for open jobs, and (b) the firms are prejudiced in any way....

Two satellites, A and B, both of mass m = 115 kg, move in the same circular orbit of radius r = 7.57 106 m around Earth but in opposite senses of rotation and therefore on a collision course. a) What is the total mechanical energy EA + EB of the two satellites + Earth system before the collision? b)If the collision is completely inelastic so that the wreckage remains as one piece of tangled material (mass = 2m), what...

Two electrons in the same atom both have n = 6 and ℓ = 2. Assume the electrons are distinguishable so that interchanging them defines a new state. (a) How many states of the atom are possible considering the quantum numbers these two electrons can have? (b) How many states would be possible if the exclusion principle were inoperative?

Assume that there is a class named TestInterface that implements two interfaces A and B. Both the interfaces have a common method with the same signature (example int sampleMethod()). Explain how will the class define this method and how will the compiler identify, to which interface does this method belong to? Will the compiler give an error or will the program execute successfully. Give your code snippet to support your answer.

A bank faces two types of borrowers, type A and B. Both want a $225 loan. Type A repays the loan 90% of the time and type B only repays with probability 0.76. The bank doesn't observe type, but believes fraction x is type A. What does x need to be so that the bank can afford a pooling interest rate of 27.1%? Please explain, someone else answered incorrectly .29, but the correct answer should be .19 according to my...
