Influence of dough freezing on Saccharomyces cerevisiae metabolism [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2007
The need to freeze dough is increasing in bakery production. Frozen dough can be stored for a long time without quality change. The capacity of bakery production can be increased in this way, and in the same time, the night shifts can be decreased. Yeast

The Freezing Rotation Illusion [PDF]

open access: yes, 2007
The freezing rotation illusion arises when a figure is continuously rotating in front of a back and forth rotating ground. The term “freezing rotation” designates the decrease in the perceived rotation speed of a figure when the figure and ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
