The thrombin time (TT) involves the addition thrombin to platelet poor plasma to stimulate the clotting process. It reflects ability of the patient to convert fibrinogen to fibrin but is also sensitive to the presence of inhibitors that may be present in the plasma, like heparin. Therefore, it can be used to measure the effects of heparin on a coagulation sample.
This assay would be used to help rule-out heparin contamination in a coagulation sample:
In DNA complementary base pairing, guanine and cytosine pair and adenine and thymine base pair.
Remembering the phrase "G-CAT" helps one recollect correct pairing.
Which nitrogen base would bind with a guanine nucleotide in forming double-stranded DNA?
Gluconeogenesis is the formation of glucose from noncarbohydrates when carbohydrate intake is absent, a fasting state. The hormone cortisol along with glucagon and epinephrine all stimulate this metabolic pathway.
Insulin; however, inhibits this pathway and is therefore the correct answer.
Which of the following hormones inhibits gluconeogenesis, the formation of glucose from noncarbohydrate sources such as amino acids, glycerol, and fatty acids?
Intravascular hemolysis is typically associated with increased levels of serum (plasma) LDH and bilirubin, and an increased number of reticulocytes. Serum LDH is found in higher levels during intravascular hemolysis due to fact that high levels of LDH are normally found within the red cells, but is now being spilled into the bloodstream via red cell lysis. Bilirubin is a breakdown product of hemoglobin, which has also been spilled into the bloodstream from broken red blood cells via hemolysis. Reticulocytosis is a reflection of the release of an increased number of immature red blood cells from the marrow to account for the red blood cells that are lost through hemolysis. This is a normal response. Failure to show an increased reticulocyte count with hemolytic episodes or hemorrhage would indicate an ineffective erythropoiesis (possible bone marrow function problem).
Which of these blood levels will increase during intravascular hemolysis?
