The heart rate (HR) was monitored (Polar
®RS800CX, Helsinki, Finland) throughout the entire YoYoIE2. After the YoYoIE2, the participants remained seated wearing the goggles for HR recording (recovery). Just after the YoYoIE2, the player indicated (individually to prevent bias) a score for his rate of perceived exertion (RPE) via the Borg CR10 scale ranging from 0 (“nothing at all”) to 10 (“very very hard”) to determine the internal intensity of the session

Check if the same lab product or an alternative is used in the 5 most similar protocols
One-step hyperglycemic clamps were performed on conscious animals as described [41] (link). A 20% dextrose solution was infused through the jugular vein to clamp plasma glucose at 18 mM for 100 min and was adjusted based on glucose measurements (Roche Accu-Check; Roche, Indianapolis, IN). At 90 min, an arginine bolus injection was performed (1 mmol/kg; Sandoz Canada) to assess the maximal insulin response. Plasma samples were collected from the tail at several time points during the clamp for insulin measurements using a mouse insulin enzyme-linked immunosorbent assay (ELISA) kit (Alpco Diagnostics, Salem, NH). Plasma samples for C-peptide measurements were collected at 75 min and analyzed using a mouse C-peptide ELISA kit (Alpco Diagnostics). Two-hour hyperinsulinemic-euglycemic clamps were performed in ASK1 wild-type and knockout mice as previously described [41] (link). Briefly, following a 1-min bolus insulin infusion (85 mU/kg; Humulin R), insulin was infused at 5 mU/kg/min. Twenty percent dextrose was infused starting 5 min after the insulin infusion to clamp glycemia at ∼6.5 mM. The insulin sensitivity index (M/I) was calculated as the glucose infusion rate (M) divided by the average insulinemia during the last 60 min of the clamp (I).

Glucose and Insulin Tolerance Tests

Blood glucose was measured in total blood using an Accu-Check glucometer (Roche). Glucose tolerance tests, pyruvate tolerance tests, and insulin tolerance tests were performed in 4-week-old OGTLKO and control OGTLWT littermates. For glucose tolerance tests, mice were fasted 4–5 h and received 2 g/kg of glucose; for pyruvate tolerance tests, mice were fasted overnight and received 1 g/kg of pyruvate; and for insulin tolerance tests, mice were fasted 4–5 h and received 0.75 U/kg of insulin. Blood glucose concentrations were measured over a period of 120 min for all tests.

IPGTT was performed at week 16 (data not shown) and week 20 using the Accu-Check glucometer monitor and strips (Roche Diagnostics, West Sussex, UK) [32 (link)]. After an overnight fast, baseline blood glucose (time 0) was determined; then a glucose solution (25%; 2 g/kg, i.p) was injected, followed by the determination of blood glucose levels at 30, 60, and 120 min. The area under the curve of glucose was calculated [33 (link)].

Intraperitoneal Glucose Tolerance Test

After 8 h fasting, Intraperitoneal Glucose Tolerance Test (IPGTT) was performed through the administration of a glucose solution (2 g/kg) in the rats (n = 8 per group). A hand-held Accu-Check glucometer (Roche Diagnostics, Indianapolis, IN, USA) was used to measure the glucose levels over a 2 h period from the tail veins. The total Area Under Curve (AUC) of the glucose and time was calculated.

Determination of Plasma Biomarkers

Whole blood was mixed with EDTA-2Na (2 mg/ml) and aprotinin (500 kIU/ml) to determine the plasma levels of FGF15, 5-HT, and insulin. Plasma insulin were measured by enzyme-linked immunosorbent assay (mouse Insulin ELISA Kit [TMB], AKRIN-011T, Shibayagi, Gunma, Japan) as described previously (12 (link)). Plasma levels of FGF15 were measured by enzyme-linked immunosorbent assay (mouse FGF15 ELISA kit, CSB-EL522052MO, WUHAN HUAMEI BIOTECH Co). Plasma 5-HT levels were measured by enzyme-linked immunosorbent assay (mouse 5-HT; BA E-5900, Labor Diagnostika Nord, Nordhorn, Germany). Blood glucose levels were measured using glucose strips (blood glucose monitoring system; Accu-Check, Roche Diagnostics, Tokyo, Japan).

Glucose and Insulin Metabolism in Mice

The mice were randomly divided into three groups (i.e., control (distilled water), standard noodles, and FLE noodles with fermented lettuce extract). After 30 min of the administration of distilled water or noodles, the mice were orally treated with 2 g/kg of glucose for OGTT or 2 g/kg of sucrose for OSTT (Table 4a,b). Blood samples were collected from the tail vein at 0, 30, 60, 90, and 120 min and blood glucose levels were measured with a blood glucose meter (Accu-check, Roche, Basel, Switzerland).
For FBGT, the mice were given an oral dose of distilled water or noodles (300 mg/kg) and blood samples were collected from the tail vein at 0, 30, 60, 90, and 120 min to measure blood glucose levels (Table 4c).
The fasting blood insulin levels were determined using a mouse insulin enzyme-linked immunosorbent assay kit (Shibayagi Co., Ltd., Gunma, Japan). To evaluate the degree of insulin resistance, HOMA-IR was calculated with the fasting blood glucose and fasting blood insulin values as follows [64 (link)]:
All animal experiments involved groups of five replicates and were repeated three times each with all types of noodles.

Glucose and Insulin Tolerance Tests

For the oral glucose tolerance test (GTT) and insulin tolerance test (ITT), cages were changed, mice were fasted for 6 h, and their weights were measured prior to testing [58] (link). For both tests, the fasting glucose levels were measured at t = 0 via tail vein blood using a glucometer (Accu-Check, Roche). For GTT, 2 g/kg dosage of glucose solution (20% D-glucose in sterile 0.9% NaCl saline solution) was orally administered using flexible plastic feeding tubes with time lapse of 2-3 min between each animal. For ITT, an intraperitoneal injection of insulin (Actrapid, UK) at a dose of 0.5UI/kg, or 0.75UI/kg (for P-HFD and C-HFD) was administered. For both OGTT and ITT, glucose measurements were measured at 15, 30-, 60-, 90-, and 120-mins post administration.

After 5 h of food deprivation, glucose was administered orally to the mice at a dose of 2.0 g/kg body weight. Blood samples were taken from the tail before and 15, 30, 60, and 120 min after glucose administration, and the blood glucose levels were measured using a blood glucose meter (Accu-Check; Roche Diagnostics, Mannheim, Germany). The blood glucose level before glucose administration represented the fasting glucose level.

Prior to an intraperitoneal glucose tolerance test (IPGTT) (n = 6 per group), rats were deprived of diet for 8 h. The IPGTT was performed through the intraperitoneal administration of glucose solution (2 g/kg body weight). Their blood was then collected from the tail veins over time and glucose levels were measured using a hand-held Accu-Check glucometer (Roche Diagnostics, Indianapolis, IN, USA). The total area under the curve (AUC) for IPGTT was calculated using the trapezoidal (trapezium) rule.

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.
