A theoretical study of a number of chiral molecules has been undertaken using a molecular Monte Carlo simulation approach coupled with calculations of molecular chirality based on a chirality order parameter. Results for a variety of TADDOL (a ,a ,a8,a8-tetraaryl-1,3-dioxolan-4,5dimethanol! derivatives show good agreement with experimental findings for the sign, magnitude, and the temperature d...

Dimerization of genomic RNA is directly related with the event of encapsidation and maturation of the virion. The initiating sequence of the dimerization is a short autocomplementary region in the hairpin loop SL1. We describe here a new solution structure of the RNA dimerization initiation site (DIS) of HIV-1(Lai). NMR pulsed field-gradient spin-echo techniques and multidimensional heteronucle...

When located in the endoplasmic reticulum (ER) membrane, B-cell receptor associated protein 31 (BAP31) is involved in the export of secreted proteins from the ER to the plasma membrane. In a previous study, we generated two monoclonal antibodies (mAbs), 297-D4 and 144-A8, that bound to surface molecules on human embryonic stem cells (hESCs), but not to surface molecules on mouse embryonic stem ...

In the present study the relation between the gluten-sensitive intestinal lesion observed in dermatitis herpetiformis (DH) and in gluten-sensitive enteropathy (coeliac sprue) (GSE) was analyzed. Jejunal IgA synthesis in DH was estimated from the extent of incorporation of [(14)C]leucine into IgA in jejunal biopsy specimens during short-term in vitro culture. Patients with DH have significantly ...

The dynamics of photodissociation of propenal at 193 nm are studied by detecting laser-induced fluorescence of nascent fragment HCO in its transition B̃ A8– X̃ A8. Rotational states up to N 530 and K53 of HCO X̃ A8 are populated and vibrational states ~000!, ~010!, and ~001! are detected. The Ka51 doublet states and the two spin states for all vibrational levels detected are nearly equally populat...

We propose that the expectation value of a circular BPS-Wilson loop in N54 supersymmetric Yang–Mills can be calculated exactly, to all orders in a 1/N expansion and to all orders in gN . Using the AdS/CFT duality, this result yields a prediction of the value of the string amplitude with a circular boundary to all orders in a8 and to all orders in gs . We then compare this result with string the...

We report elastic and electronically inelastic cross sections for low-energy electron scattering by pentafluoroethane, C2HF5 . Our calculations were performed using the Schwinger multichannel method. For elastic scattering, we calculated integral, differential, and momentum transfer cross sections for energies from 5 to 50 eV. In the inelastic case, we obtained integral and differential cross s...
