“…Some post-translational modifications of GSTs are known and include the phosphorylation of serines, tyrosines, and threonines of GSTs. 37,42 Phosphorylation of some GSTP1 residues are known to increase metabolic activity. 43 Additionally, cysteine residues of GSTP1 are known to be glutathionylated.…”

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants generated from combustion of carbon-based matter. Upon ingestion these molecules can be bioactivated by cytochrome P450 monooxygenases to oxidized toxic metabolites. Some of these metabolites are potent carcinogens that can form irreversible adducts with DNA and other biological macromolecules. Conjugative enzymes, such as glutathione S-transferases or UDPglucuronosyltransferases, are responsible for the detoxification and/or facilitate the elimination of these carcinogens. While responses to PAH exposures have been extensively studied for the bioactivating cytochrome P450 enzymes, much less is known regarding the response of glutathione S-transferases in mammalian systems. In this study, we investigated the expression and activity responses of murine hepatic glutathione S-transferases to benzo[a]pyrene exposure using global proteomics and activity-based protein profiling for chemoproteomics, respectively. Using this approach, we identified several enzymes exhibiting increased activity including GSTA2, M1, M2, M4, M6, and P1. The activity of one GST enzyme, GSTA4, was found to be downregulated with increasing B[a]P dose. Activity responses of several of these enzymes were identified as *

“…Quark delocalization color screening and chiral quark models are used to reanalyze ΩΩ dibaryon states with J P = 0 + , 1 − , 2 + , 3 − quantum numbers and J P = 0 + is found to be bound [36]. ΩΩ dibaryon states with J P = 0 + and J P = 2 + are investigated in a molecular picture by using QCD sum rule [37]. An evidence is found for a strangeness S = −1 ΣN dibaryon bound state in the ΛN cross section [38].…”

We study a hypothetical ∆ 0 ∆ 0 dibaryon state by means of QCD sum rule method. We construct a scalar interpolating current to extract the mass and decay constant of this state taking into account contributions of various quark, gluon and mixed vacuum condensates. The predictions for the mass and decay constants are mD = 2326 +114 −126 MeV and fD = 2.94 +0.30 −0.34 × 10 −4 GeV 7 , respectively. We also made an estimation about binding energy and size of the ∆ 0 ∆ 0 dibaryon. The obtained mass value is below the ∆ 0 ∆ 0 threshold and may be a good dibaryon candidate for being observed experimentally.

“…Jaffe firstly found the H particle whose hyperfine interaction is much larger than that for two separated Λ baryons within the chromo-magnetic interaction model [16], and this dibaryon uuddss was also studied within other framework [17][18][19][20][21][22][23][24]. Moreover, the heavy dibaryons (qqqqqQ) [25][26][27][28][29], doubly-heavy dibaryons (qqqqQQ) [29][30][31][32][33][34][35], triply-heavy dibaryons (qqqQQQ) [36][37][38], the other fully light dibaryons (qqqqqq) [39][40][41][42][43][44], and even fully heavy dibaryons (QQQQQQ) [45] were also proposed and discussed.…”
