Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and fibrosis of the bile ducts.
On histological examination, PSC is characterized by concentric fibrosis and inflammation that extends from the bile ducts to the surrounding liver parenchyma. This results in an “onion skin” appearance on microscopy.
The bile ducts show a variable degree of inflammation, fibrosis, and destruction. Cholestasis may be present, along with associated hepatocyte damage and inflammation. Bile duct proliferation is often seen as well. In advanced cases, cirrhosis with the loss of normal liver architecture may be observed.

When referring to dose, what term is used when the radiosensitivity of tissue is considered? What is unit?
When referring to dose, the term used when the radiosensitivity of tissue is considered is called the "equivalent dose." This is because different types of radiation have varying levels of energy and ability to damage tissue. For example, alpha particles have a high level of energy and can cause significant damage to tissue, while beta particles have a lower energy and are less damaging. Equivalent dose takes into account both the amount of radiation absorbed and the type of radiation to calculate a more accurate measure of the potential harm to the tissue.
Unit is a measure of quantity used in radiation dosimetry, and it is important to use appropriate units to ensure safety and accuracy. The SI unit for radiation dose is the gray (Gy), which represents the amount of energy deposited in the tissue per unit of mass. However, the equivalent dose is measured in sieverts (Sv), which is the absorbed dose multiplied by a radiation weighting factor that takes into account the type of radiation and the sensitivity of the tissue being exposed.
In summary, equivalent dose is the term used when the radiosensitivity of tissue is considered, and it is measured in sieverts. The use of appropriate units is essential in radiation dosimetry to ensure safety and accuracy in medical and industrial applications.

What poison produce garlic breath?
The compound responsible for giving garlic its distinct flavor and aroma is called allicin. When garlic is chopped, crushed, or chewed, it produces allicin, which is then broken down into other compounds that can cause bad breath. However, allicin itself is not considered a poison.
There are some poisonous plants that can produce a garlic-like odor when consumed or even just touched. These include wild onion, crow garlic, and death camas. These plants contain toxic compounds such as lycorine and/or other alkaloids that can cause symptoms ranging from mild gastrointestinal upset to more serious effects like seizures and respiratory failure.
It's important to note that garlic itself is not poisonous and is safe for most people to consume in moderate amounts.

Coughing forces the trachea (windpipe) to contract, which affects the velocity v of the air passing through the trachea. Suppose the velocity of the air duFind theg coughing is v = k(R - r)r^2 where k is a positive constant, R is the normal radius of the trachea, and r is the radius duFind theg coughing. What radius duFind theg coughing will produce the maximum air velocity? (When differentiating v, explain how you differentiate it! And then, explain every step!)
The radius duFind theg coughing that produces the maximum air velocity is r = 2R/3.
To find the radius that produces the maximum air velocity, we need to maximize the function v with respect to r.
v = k(R - r)[tex]r^2[/tex]
To maximize v, we need to find the critical points, which are the values of r where v' = 0.
v' = k(R - r)(2r) - k([tex]r^2[/tex])
v' = 2kr(R - r) - k[tex]r^2[/tex]
Setting v' = 0 and solving for r, we get:
2kr(R - r) - k[tex]r^2[/tex] = 0
2Rr - 2[tex]r^2[/tex] - [tex]r^2[/tex] = 0
3[tex]r^2[/tex]- 2Rr = 0
r(3r - 2R) = 0
r = 0 or r = 2R/3
Since r = 0 would make no physical sense, the only critical point is r = 2R/3. To show that this is a maximum, we need to check the second derivative of v:
v'' = -2k(R - 2r)
When r = 2R/3, v'' = -2k(R - 4R/3) = -2kR/3 < 0, which means that r = 2R/3 is a maximum.

The nurse would use blood pressure as the primary indicator to determine the effectiveness of sublingual nitroglycerin.
Sublingual nitroglycerin is a medication used to treat angina, a condition caused by insufficient blood flow to the heart. Nitroglycerin causes vasodilation of the blood vessels, which results in increased blood flow to the heart and decreased workload on the heart. A decrease in blood pressure indicates that the medication is working and that blood flow to the heart has improved.
The nurse would monitor the patient's blood pressure before and after administration of sublingual nitroglycerin to assess its effectiveness.
