The true effects of variations of the design are, however, not completely known. There are only few randomised clinical trials in this field and most of them did not try to isolate single factors, but rather compared two completely different de- signs. Some kinematic studies had limited resolu...
The 16S rRNA gene and the ITS region were targeted in PMA-qPCR to measure intact/viable bacterial and fungal burden, respectively. The changes were not significantly different (P > 0.05), although the average number of bacterial 16S rRNA gene copies trended toward increase from F1 to F3...
The lactodynamograph is the instrument most commonly used at laboratory level to assess MCP of a large number of milk samples per day. This instrument simulates the cheese-making process through the heating of milk and the addition of rennet, and records 3 single-point traits: rennet ...
e, Ratios of mean total UMI counts of tumor cells to non-tumor cells (n = number of tumor cells / number of non-tumor cells) and 95% CIs in pooled scRNA-seq data (pseudo-bulk) from ten patients with colorectal (n = 3, including patients 1 and 2 shown in b–d), ...
