This week, we are learning about communicable diseases
or those diseases that are infectious and the role of public health
in detection, treatment, prevention and in some cases
eradication. Select a topic from below and post your
discussion. Make sure to provide an example in your
discussion post.
Discuss the burden of disease caused by communicable
diseases and provide an example.
Discuss the criteria that are used to establish that
an organism is a contributory cause of a disease
Discuss the factors that affect the transmissibility
of a disease and provide an example
Discuss the roles that barrier protections play in
preventing communicable diseases and provide an example
Discuss the roles that vaccinations can play in
preventing communicable diseases and provide an example
Discuss the roles that screening, case finding, and
contact treatment can play in preventing communicable
diseases
Discuss the conditions that make eradication of a
disease feasible
Discuss a range of options for controlling the
HIV/AIDS epidemic and provide an example
Your post must be at minimum two paragraphs (five
sentences per paragraph) in APA format (in text citations and
bibliography).

1. Explain how RNAi could be used to treat disease.
2. What are two specific ways in which RNAi can block the production of proteins.
3. RNAi exerts its effect by mainly controlling which process?
a. Termination
b. Translation
c. Transcription
d. Replication
e. Splicing
4. Which of the following is not true about miRNA?
a. One miRNA may match multiple targets
b. miRNA is used by scientist as a therapy
c. miRNA is found in plants and animals
d. miRNA is a product of a gene
5. An RNA molecule that loops to base pair with itself is called a.............. RNA because of its characteristic shape.
6. Suppose that you wish to target a gene using siRNA. The sense strand of the gene that is the DNA strand codes for the mRNA contains 21 base sequence: 5' TCGGAGCAAATAGGTAGGCA 3' What would be the most appropriate 21 base guide strand sequence that would target the mRNA?

5. A patient with chronic-stable angina begins taking metoprolol, and once blood levels reach the therapeutic range the frequency and severity of angina attacks and the need for sublingual nitroglycerin were reduced. Which of the following states the direct pharmacologic action by which the beta-blocker produced the desired effects? A. Decreased myocardial oxygen demand
B. Dilated coronary vasculature
C. Directly inhibited angiotensin II synthesis
D. Reduced total peripheral resistance
6. A patient with newly diagnosed essential hypertension starts treatment with a commonly used antihypertensive drug at a dose that is considered to be therapeutic for the vast majority of patients. Soon after starting therapy the patient experiences crushing chest discomfort. ECG changes show myocardial ischemia. Studies in the cardiac catheterization lab show episodes of coronary vasospasm, and it is likely the antihypertensive drug provoke the vasospasm. Which antihypertensive drug most likely caused the ischemia and the angina?
A. Atenolol
B. Diltiazem
C. Hydrochlorothiazide
D. Lozartan
7. A 28-year-old woman is receiving drug therapy for essential hypertension. She subsequently becomes pregnant. You realize that the drug she's been taking for her blood pressure can have serious, if not fatal, effects on the fetus. As a result, you stop the current antihypertensive drug and substitute it with another drug that is deemed to be equally effective in terms of her blood pressure, and safer for the fetus. Which of the following drugs was she most likely taking before she became pregnant?
A. Alpha-Methyldopa
B. Captopril
C. Furosemide
D. Labetalol E. Verapamil
8. The use of propranolol as an antiarrhythmic agent is contraindicated in patients with:
A. COPD
B. Asthma
C. Severe heart failure
D. A and C
E. All of the above
