Using a structure-based coarse-grained model of proteins, we study the mechanism of unfolding of knotted proteins through heating. We find that the dominant mechanisms of unfolding depend on the temperature applied and are generally distinct from those identified for folding at its optimal temperature. In particular, for shallowly knotted proteins, folding usually involves formation of two loop...

9-beta-d-Arabinofuranosyladenine (ara-A) was deaminated to 9-beta-d-arabinofuranosylhypoxanthine by adenosine deaminase present in fetal bovine serum, newborn calf serum, and calf serum used to supplement tissue culture media. Heating newborn calf serum or calf serum for 12 h at 56 C completely eliminated the enzymatic deamination of ara-A. The deaminase activity associated with fetal bovine se...

In this article, some diagnostic systems and the preliminary results of the IR-T1** (Iran-Tokamak 1) are presented. Different diagnostic methods, including an array of soft X-ray detectors, visible spectrometer, electron cyclotron emission detector and electromagnetic measurement systems have been used and the hard disruptive instability occurring in the IR-T1 plasma during an ohmic heating...

the present study was conducted to determine the relative contribution of initial quality and compositional parameters to the rate of changes (rctpc) in the content of total polar compounds (tpc), which is considered to be one of the most reliable indicators of heated oils quality, of olive oil during continuous heating at 180 ºc. the ratio between monounsaturated and polyunsaturated fatty acid...
