Working in the nonrelativistic-QCD factorization framework at next-to-leading order ${\ensuremath{\alpha}}_{s}$, we fit relevant color octet long-distance matrix elements of $\ensuremath{\psi}(2S)$ meson, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{1}S}_{0}^{[8]})⟩$, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}S}_{1}^{[8]})⟩$, and $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}P}_{0}^{[8]})⟩$, to...

Drosophila melanogaster 5.8S and 2S rRNAs were end-labeled with 32p at either the 5' or 3' end and were sequenced. 5.8S rRNA is 123 nucleotides long and homologous to the 5' part of sequenced 5.8S molecules from other species. 2S rRNA is 30 nucleotides long and homologous to the 3' part of other 5.8S molecules. The 3' end of the 5.8S molecule is able to base-pair with the 5' end of the 2S rRNA ...

Monothiol glutaredoxins play a crucial role in iron-sulfur (Fe/S) protein biogenesis. Essentially all of them can coordinate a [2Fe-2S] cluster and have been proposed to mediate the transfer of [2Fe-2S] clusters from scaffold proteins to target apo proteins, possibly by acting as cluster transfer proteins. The molecular basis of [2Fe-2S] cluster transfer from monothiol glutaredoxins to target p...

A series of optically active poly(diphenylacetylene) derivatives bearing a chiral substituent (poly-2S) or chiral and achiral substituents (poly-(2Sx-co-31-x)) on all of their pendant phenyl rings were synthesized by the reaction of poly(bis(4-carboxyphenyl)acetylene) with (S)-1-phenylethylamine ((S)-2) or benzylamine (3) in the presence of a condensing reagent. Their chiroptical properties and...

The present invention provides a new process for the preparation of 2S,3S-N-isobutyl-N-(2-hydroxy-3-amino-4phenylbutyl)-p-nitrobenzenesulfonylamide hydrochloride, wherein this compound is prepared directly from the chloromethylalcohol. Importantly, the process of the present invention results in higher yields of 2S,3S-N-isobutyl-N-(2hydroxy -3 -amino -4-phenylbu tyl) -pnitrobenzenesulfonylamide...

We use terahertz pulses to induce resonant transitions between the eigenstates of optically generated exciton populations in a high-quality semiconductor quantum well sample. Monitoring the excitonic photoluminescence, we observe transient quenching of the 1s exciton emission, which we attribute to the terahertz-induced 1s-to-2p excitation. Simultaneously, a pronounced enhancement of the 2s exc...

In the last few years, the CLEO III experiment has recorded a large collection of data sets at the Υ(1S), Υ(2S), Υ(3S) and ψ(2S) resonances. Preliminary results of studies of these data sets are shown here, which include the observation of a new Υ(1D) state, as well as several hadronic and radiative transitions of Υ and ψ(2S) states. In addition, precision branching ratio measurements of charmo...

We describe the practical synthetic route for (2S)-7-methoxy-1,2,3,4-tetrahydro-2-naphthylamine 1(2S)-2-amino-7-methoxytetraline; (S)-AMT]. (2R)-2-(3-Methoxybenzyl)succinic acid [(R)-1] was obtained by the optical resolution of 2-(3-methoxybenzyl)succinic acid (1) as the salt of (1R,2S)-2-(benzylamino)cyclohexylmethanol (7), and (R)-1 was converted to the optically active (2S)-7-methoxy-1,2,3,4...

3,7-Dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were identified in female whole body extracts from the two pine sawfly species Gilpinia frutetorum and Gilpinia socia. This is the first observation of 3-methylpentadecan-2-ol in extracts of a female pine sawfly species. Synthetic and highly pure stereoisomers of 3,7-dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were used to verify t...

The GABAA receptor 2 subunit mutation R43Q is an autosomal dominant mutation associated with childhood absence epilepsy and febrile seizures. Previously, we demonstrated that homozygous 1 3 2L(R43Q) receptor whole-cell currents had reduced amplitude with unaltered time course, suggesting reduced cell surface expression of functional receptors. In human embryonic kidney 293-T cells, we demonstra...
