Answer:

The thyroid gland absorbs almost all of the iodine in the body. When radioactive iodine (RAI), also known as I-131, is given to the body as a liquid or capsule, it becomes concentrated in thyroid cells. Radiation can kill the thyroid gland and any other thyroid cells or tissues (including cancer cells) that absorb iodine, without damaging any other organs.

Explanation:

The thyroid gland is an organ that belongs to the endocrine system and its function is to synthesize hormones that are responsible for controlling the body's metabolism, this gland has an important characteristic and that is that the hormones it produces have a unique chemical composition due to They are the only hormones that contain iodine in their structure, this in turn is essential for its functioning because the body does not synthesize it and it must be consumed in the diet. When a small dose of the radiopharmaceutical iodine 131 (Sodium Iodide 131I) is consumed, it is absorbed into the bloodstream and concentrated by the thyroid gland, where it begins to destroy cancer cells in the gland. 131I quickly attaches itself to thyroid cells to destroy them, but continues to emit radioactivity for a long time: it takes 8 days to halve. The beta radiation particles of 131I, which we call radioiodine or radioactive iodine, have a range of 2mm and act for a long time in a constant way. Fortunately, the body's metabolism quickly expels iodine through the urine, so that in one day the amount of iodine has decreased considerably.

a term named for a person or a place, such as alzheimer disease named for the physician who first described the symptoms as seen

AysviL [449]

A term named for a person or a place, such as alzheimer disease named for the physician who first described the symptoms as seen in a patient, is referred to as Eponym.

<h3>What is Eponym?</h3>

This is referred to as a place or a thing which is believed to be named after something and in this case, it is referred to as what we call Alzheimer which is common with older people.

Alois Alzheimer is referred to as a German neuropathologist who identified the first published case of presenile dementia in 1906 through the various symptoms he observed in the patient.

This was the reason why when this condition was fully confirmed by others later on it was named after him and is being referred to as Alzheimer disease today.

This is therefore the reason why Eponym was chosen as the most appropriate choice.

Stells [14]

A client has been diagnosed with a heart attack and has been placed on beta-blockers to reduce the workload on the heart, as well as a statin drug and a low-fat diet to lower cholesterol. These therapies would be classified as Primary and tertiary level of prevention of disease.

<h3>What is a Heart attack? </h3>

When the blood supply to the heart is significantly constrained or blocked, a heart attack takes place.

The clogging of the heart’s (coronary) arteries is frequently caused by the accumulation of fat, cholesterol, and other substances. The fatty, cholesterol-rich growths are called plaques.

Atherosclerosis is the name for the accumulation of plaque. Rarely, a plaque may rupture, resulting in the formation of a clot and the obstruction of blood flow.

A section of the heart muscle might be harmed or even destroyed by a decrease in blood flow. Myocardial infarction is another name for a heart attack.

Treatment must be received right away if someone is to survive a heart attack. If you think you’re experiencing a heart attack, call 911 or get medical help right away.

Symptoms of a heart attack might vary. Some people experience mild symptoms. Others exhibit severe symptoms. Some people don’t exhibit any symptoms.

<h3>What are beta blockers? </h3>

The primary uses of the beta blocker pharmacological class, which is frequently abbreviated as “blockers,” are the treatment of irregular heartbeats and the prevention of subsequent heart attacks.

Which best describes the different mechanisms of mitoxantrone and carboplatin

Dima020 [189]

Answer:

Explanation:

Carboplatin undergoes activation inside cells and forms reactive platinum complexes that cause the intra- and inter-strand cross-linkage of DNA molecules within the cell. This modifies the DNA structure and inhibits DNA synthesis. This may affect a cell in all the phases of its cycle.
