Plasma glucose was assayed by the glucose oxidase method (Beckman II, Glucose Analyser, Fullerton CA); HbAlc was determined by high-performance liquid chromatography (DIAMAT, Bio-Rad, Richmond, CA, USA); plasma triglycerides and total cholesterol were determined enzymatically (Boehringer Mannheim, Germany). High-density lipoprotein (HDL)-cholesterol was measured by precipitation with heparin and MgCl₂ on whole plasma, whereas low-density lipoprotein (LDL)-cholesterol was calculated by Friedewald’s formula.
THPO levels in plasma were quantified using a specific ELISA kit (R&D Systems) following the manufacturer’s instructions. The lower detection limit of the assay was 7.45 pg/mL.

Tissue-Plasma Glucose Dynamics Monitoring

Check if the same lab product or an alternative is used in the 5 most similar protocols

The time delay between plasma and tissue during plasma glucose concentration increase (BT↑) was measured as time between maximum glucose concentration increase rates in plasma and tissue. Maximum glucose concentration increase in tissue was measured by CGMS. Similarly, the time delay at glucose concentration decrease (TB↓) was measured as the difference in CGMS and Beckman values at maximum decrease rates in tissue (measured by CGMS) and plasma glucose decrease rate. Both quantities are well defined from the mathematical point of view. BT↑ is defined as the time difference between inflex points of plasma and tissue glucose concentration when the glucose concentration increases. TB↓ is defined in the same manner when the glucose concentration in venous plasma decreases.
Capillary plasma glucose concentration was measured by the glucometer-strip (glucoseoxidase) system Calla and on the analyser Beckman II using glucoseoxidase enzyme. The best correlation between Beckman analyser and system Calla proved the accuracy of plasma glucose measurement and correct CGMS calibration using glucometer Calla.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
