Diana jones is 5'4" and weighs 145 pounds. would the anesthetic choices be the same for diana as they would be for a 6'3" 210 lb
ankoles [38]

Answer:

Propofol (another name Diprivan) can be used for Diana's surgery. It is a sedative or anesthesia commonly used for children and adults. Studies show that there were no significant differences in dose requirements based on sex or age, except for the too elderly.  The difference in dosing considering different body weights were not statistically significant also.  The same dose is safe

( 0.1-0.15 mg/kg/min IV for 3-5 min) for Diana, the 210 lb man or a 10-year-old girl. However, the dose was higher in patients with bradycardia and hypotension.

The metabolic fate of fatty acids is dependent on two enzymes, carnitine acyltransferase i and acetyl-coa carboxylase. carnitine
zvonat [6]

The correct answer is the last statement.

If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.

It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.

In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
