Glycemic Response to Isomaltulose and Sucrose

Check if the same lab product or an alternative is used in the 5 most similar protocols
Blood glucose levels were measured using OneTouch Verio (LifeScan Europe, Johnson & Johnson, Sug, Switzerland). OneTouch Verio uses a finger prick to collect a blood sample via test strips which are accurate and precise over a wide range of patients and environmental and pharmacologic conditions [20 (link)]. After a 10–12 h overnight fast period, two fasting blood drops were collected 5 min apart. If the difference between the two fasting blood glucose levels was more than 0.2 nmol/L, a third blood drop was collected. Then, participants were randomly given a test beverage with either a low (isomaltulose) or a high (sucrose) glycemic index. Then, 50 ± 0.01 g of sucrose (Kristalsuiker, Delhaize, Brussels, Belgium) or isomaltulose (Palatinose™, provided by BENEO, Brussels, Belgium) was measured on a calibrated electronic laboratory scale (AX124, Sartorius, Goettingen, Germany) and dissolved in 250 ± 0.1 mL of plain drinking water measured out with volumetric laboratory equipment. Afterward, blood glucose levels were collected at 15, 30, 45, 60, 90, and 120 min after consumption of the beverages. The first two drops of blood were discarded, and the third drop was used for testing. The same procedure was applied during the first and second assessment sessions.

Measuring Weights and Anogenital Distance

Check if the same lab product or an alternative is used in the 5 most similar protocols
Body weights of C- and R-females/fetuses/offspring were measured with a portable balance (EK-3000i) (A&D, Tokyo, Japan), and testis weights of C- and R-offspring were measured with an analytical electronic balance (AX124) (Sartorius AG, Göttingen, Germany). AGD was measured with a Digimatic Caliper (Mitsutoyo, Kawasaki, Japan) under a EZ4 D microscope (Leica, Wetzlar, Germany). The AGD index (AGDI) was also calculated by diving the AGD by the cube root of body weight [17 (link)], to allow for comparison of AGDs between C-fetuses and R-fetuses with different body size.

Cadmium Distribution in Maize Leaves

Check if the same lab product or an alternative is used in the 5 most similar protocols
We determined Cd concentrations in one-centimetre segments sampled along the maize leaf growth zone (i.e. 10 centimetres in total) and included a blade segment (middle of the remaining blade). Fresh weight of the sampled leaf segments was measured (AX124, Sartorius, Göttingen, Germany), after which they were oven-dried at 60 °C for 48 to 72 hours.
Hereafter, segments from the same position and treatment were pooled (2-3 segments per pool). Sample digestion was performed by an overnight predigestion in aqua regia (1:3 nitric acid and hydrochloric acid), followed by 20 minutes high pressure high temperature digestion (Discover SP-D, CEM, Matthews, NC, USA), allowing the samples to boil at 200 °C. The samples were then diluted 40 times with trace metal grade ultrapure water, after which the Cd concentration was measured with high resolution inductively coupled plasma mass spectrometry (Element XR, Thermo Scientific, Bremen, Germany). We used blanks to correct for background trace metals and Rye grass European Reference Material CD281 samples as a reference.

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.
