The constrained opioid peptide (2S,3R) -methyl-2 ,6 -dimethyltyrosine-L-tetrahydroisoquinoline-3-carboxylic acid [(2S,3R)TMT-LTic-OH] exhibits high affinity and selectivity for the -opioid receptors (Liao et al., 1997). In the present study, we examined the pharmacological properties of (2S,3R)TMT-L-Tic-OH in mouse brain. A 5 -O-(3-[S]thiotriphosphate) ([S]GTP S) binding assay was used to deter...
4-Fluoroprolines are among the most useful nonnatural amino acids in chemical biology. Here, practical routes are reported for the synthesis of the 2S,4R, 2S,4S, and 2R,4S diastereomers of 4-fluoroproline. Each route starts with (2S,4R)-4-hydroxyproline, which is a prevalent component of collagen and hence readily available, and uses a fluoride salt to install the fluoro group. Hence, the route...
Measurements of branching fractions for ψ(2S) decays into ωππ, b1π, ωf2(1270), ωKK, ωpp̄, φππ, φf0(980), φK K, and φpp̄ final states, based on a data sample of (4.02 ± 0.22) × 10 ψ(2S) events collected with the BESI detector at the Beijing ElectronPositron Collider, are reported. Using the same event sample, radiative decays of the radially excited charmonium resonance, ψ(2S), into ππ, KK and ηη ...

We prove that there is ǫ > 0 and p0 > 0 such that for every prime p > p0, every subset S of Z/pZ which satisfies |2S| ≤ (2 + ǫ)|S| and 2(|2S|) − 2|S| + 3 ≤ p is contained in an arithmetic progression of length |2S| − |S| + 1. This is the first result of this nature which places no unnecessary restrictions on the size of S.
For any positive integer s, a [2, 2s]-factor in a graph G is a connected even factor with maximum degree at most 2s. We prove that if every induced S(K1,2s+1) in a graph G has at least 3 edges in a block of degree at most two, then G has a [2, 2s]-factor. This extends the results of Hendry and Vogler and of Abderrezzak et al.
We present a search for direct CP violation in B → J/ψ K and B → ψ(2S)K decays. In a sample of 9.7 × 106 BB meson pairs collected with the CLEO detector, we have fully reconstructed 534 B → J/ψK and 120 B → ψ(2S)K decays with very low background. We have measured the CP -violating charge asymmetry to be (+1.8 ± 4.3[stat] ± 0.4[syst])% for B → J/ψ K and (+2.0 ± 9.1[stat]± 1.0[syst])% for B → ψ(2...
MitoNEET (mNT) is an outer mitochondrial membrane target of the thiazolidinedione diabetes drugs with a unique fold and a labile [2Fe-2S] cluster. The rare 1-His and 3-Cys coordination of mNT's [2Fe-2S] leads to cluster lability that is strongly dependent on the presence of the single histidine ligand (His87). These properties of mNT are similar to known [2Fe-2S] shuttle proteins. Here we inves...
Monolayer transition metal dichalcogenides (TMDs) host a variety of optically excited quasiparticle species that stem from two-dimensional confinement combined with relatively large carrier effective masses and reduced dielectric screening. The magnetic response these quasiparticles gives information on their spin valley configurations, nuanced interactions, insight into the underlying band str...
