Namely, CSF infection showed a proportionally greater response to treatment than plasma infection in the face of antiviral drug resistance.
As described previously [ 21], this rabbit model of prolonged critical illness is characterized by low T3 plasma concentrations in the face of decreased TSH levels.
The diagnosis of an islet cell tumor is based on the persistence of inappropriately increased plasma insulin concentrations in the face of a low glucose concentration.
However, equivalent plasma insulin and C-peptide levels (i.e., increased Δ I/Δ G and ΔISR/Δ G) in the face of a lower plasma glucose concentration after S (compared with P) indicates that β-cell function improved.
These findings are consistent with an adaptive physiologic response that is aimed at the maintenance of blood pressure in the face of reduced plasma volume.
Vasopressin neurons homeostatically regulate plasma volume and body fluid electrolyte composition in the face of (a) differential and variable loss of fluid and electrolytes through sweating and urine flow, and (b) perturbation by fluid and electrolyte intake.
Typically, high insulin levels are maintained in the face of high plasma glucose, due to the reduced effects of insulin on fat, liver, and muscle cells.
None of the 28 patients showed persistent CSF virus in the face of undetectable plasma VL.
Their claim was supported by work that demonstrated that epinephrine can accelerate hemodynamic recovery [ 4], reverse slowed action potential conduction, shorten action potential duration, and improve myocardial contractility in the face of increased plasma concentrations of bupivacaine [ 5].
Using the euglycemic clamp technique to maintain stable plasma glucose and insulin levels during the night, McMahon and colleagues have more recently shown that the rate of exogenous glucose infusion had to be sharply increased 7 11 h after afternoon exercise, even in the face of unchanged plasma insulin concentrations (4).
