To fully characterize the atmospheres, or lack thereof, of terrestrial exoplanets, we must include high-energy environments provided by their host stars. The nearby mid-M dwarf LHS 3844 hosts a world that lacks substantial atmosphere. We present time-series UV spectrum from 1131 to 3215 Å captured HST/COS. detect one flare in FUV has an absolute energy 8.96 ± 0.77 × 1028 erg and equivalent dura...

CRM 228 (T. Uchida, A. M. Pappenheimer, and R. Greany, J. Biol. Chem. 248:3838-3844, 1973), a mutant form of diphtheria toxin which completely lacks ADP-ribosyltransferase activity, contains five amino acid substitutions. The two amino acid changes that fall within the A chain of the toxin (G79D and E162K) were separately analyzed by substituting a variety of other amino acids at these sites. T...

Figure 1. Key performance indicators for Advanced Science during the first years. Table 1 presents the highest cited papers in 2016 (published in 2014 and 2015) which will be the main driving force for the next ISI impact factor. Popular topics include solar cells, batteries, but also photocatalysts, metal-organic frameworks, and hydrogel composites. Since the journal was included in PubMedCent...

The oxy-myoglobin (Mb-O2) structure was probed by QM/MM (hybrid quantum mechanical/ molecular mechanical) calculations using DFT/MM to elucidate the effect of the heme propionates and the protein matrix on the chemistry of heme Fe-O2 moiety. On this line, we have probed the role of His97 in various protonation states of the heme propionate-6.

The activities of the mitochondrial NAD(P)+- and NADP+-dependent malic enzymes were measured in 11 tissues of the male Sprague-Dawley rat. The NAD(P)+-dependent malic enzyme was present in small intestinal mucosa, spleen, thymus, lung, and testis. Each of these tissues contain cells that are undergoing active rates of renewal. The NADP+-dependent malic enzyme was not confined to tissues undergo...
