Several technical reasons may explain our distinctive findings, including differences in the microbiome sampling site, the limited n per group, singly housing mice, or the use of highly similar lean, Western, and high-fat diets which systematically exchanged fat content with carbohydrate content
Second, the BDNF and NGF mRNA upregulation triggered by a single dose continues for 12 to 24 hours and drives sustained behavioural change
Non-Responders (5-15% of users): See minimal or no improvement despite consistent dosing
The sample was treated with a solution of glacial acetic acid (20% v/v), sodium dodecyl sulfate (8.1% v/v), and thiobarbituric acid (0.8% w/v) before being incubated for 1 h at 95 C in a water bath
The instrument was calibrated using 0, 5, 10, 50, 100 and 500 ppb of certified multi-element ICP-MS standard calibration solutions (ICP-MS-CAL2-1, ICP-MS-CAL-3 and ICP-MS-CAL-4, Accustandard) for a range of elements
