Ethyl carbamate formation in sub-optimal wine storage conditions and influence of the yeast starter
OENO One, 2013 Aim: To evaluate the potential risk of ethyl carbamate (EC) formation in wine by studying its production kinetics at sub-optimal storage temperatures. Methods and results: The kinetics of EC formation was investigated in 60 white wines obtained from 6 ...

Studies on the denaturation of antibody: II. The effect of protein concentration on the rate of denaturation of diphtheria antitoxin by urea [PDF]
, 1945 The specific rate of inactivation of antitoxin in urea solutions, as measured by the Römer neutralization test with toxin, has been shown to be independent of the concentration of protein under the conditions studied.

The crystal structure of urea oxalic acid (2:1) [PDF]
, 1972 The crystal structure of urea oxalic acid, 2[CO(NH2)2].(COOH)2 has been determined using three-dimensional X-ray data, collected on an automatic diffractometer. The space group is P21/c. The lattice constants are: a = 5.058 (3), b = 12.400 (3), c = 6.964

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