Sulfur mustard is a chemical warfare agent that causes blistering of the skin and damages the eyes and airway after environmental exposure. We have previously reported that thiodiglycol (TDG, 2,2'-bis-thiodiethanol), the hydrolysis product of sulfur mustard, is oxidized by alcohol dehydrogenase (ADH) purified from horse liver or present in mouse liver and human skin cytosol. Humans express four...
Nerve growth factor (NGF) supports target-dependent survival of sympathetic and other neurons during development; however, the NGF-regulated signaling pathways required for survival are not fully understood. Sympathetic neurons are able to abort acutely the cell death pathway initiated by NGF deprivation at early, as well as late, time points after readdition of NGF. We found that NGF-dependent...
We present a model of self-interacting dark matter based on QCD-like theories and inspired by the proximity $a_0(980\pm 20)$ to $K\bar{K}(990)$ threshold. Dark is comprised pions which self-scatter via $\sigma$ resonance close $\pi\pi$ While linear sigma serves as qualitative guide, fully unitary description scattering in strongly coupled regime given effective range theory. The introduction ki...
Structure and properties (energies, electronic, and thermodynamic properties) of complexes pyridine-XY (X, Y = F, Cl, Br) have been investigated at the MP2/aug-cc-pVDZ level. Two types of geometries (pi-halogen bonded and sigma-halogen bonded) are observed. In contrast with the previous results on similar furan and thiophene complexes, the sigma-halogen bonded structures are more stable and the...

We report on photoassociation spectroscopy probing the ${c}^{3}{\mathrm{\ensuremath{\Sigma}}}_{1}^{+}$ potential of bialkali NaCs molecule, identifying 11 vibrational lines between ${v}^{\ensuremath{'}}=0$ and ${v}^{\ensuremath{'}}=25$ excited fitting their rotational hyperfine structure. The observed are assigned by to an effective Hamiltonian model excited-state structure with constants as fr...
