Acrylic monomers are known to undergo autoinitiation at high temperatures (>200 °C) via a Flory-type autoinitiation mechanism, whereby two monomers react via an open-shell singlet pathway to form diradical species (Fig. 5a)37,39,40,41. However, autoinitiation at lower temperatures has ...
Mitomycin C (MMC), a quinone-containing antitumor drug, has been shown to alkylate DNA and to form DNA cross-links. The ability of MMC to alkylate O 6-guanine and to form interstrand cross-links (ISC) has been studied using Mer + and Mer human embryonic cells. Mer + (IMR-90) cells...

It should be noted that some AOPs might be costly or form un-desirable byproducts (Nidheesh et al., 2013; Sirés et al., 2014), which limited their practical applications. Numerous efforts have been put to investigate and develop different types of efficient AOPs, for example, various ...

The latter is obtained in the form of a border or Gr枚bner basis. The algorithm is based on moment relaxations and, in contrast to other existing methods, it exploits the real algebraic nature of the problem right from the beginning and avoids the computation of complex components....
It was anticipated that the temperature shift to 42°C promotes folding of the thermostable enzyme to its biologically active form. The culture growth was continued for 19 hours (h) at 42°C. Bacterial pellets from both the control, non-induced and induced cultures were subjected to SDS/PAGE...
