TL;DR: In this paper, the authors extracted charge and transverse energy distributions for intermediate mass fragments for central Kr1Au collisions at E/A5352400 MeV and showed that the slopes of the measured fragment charge distributions decrease monotonically with incident energy, consistent with the expectations for highly charged systems.
Abstract: Charge and transverse energy distributions for intermediate mass fragments have been extracted for central Kr1Au collisions at E/A5352400 MeV. The slopes of the measured fragment charge distributions decrease monotonically with incident energy, consistent with the expectations for highly charged systems, but not with recent critical exponent analyses. Statistical model calculations, which reproduce the experimental trends, suggest that post-breakup fragment secondary decays alter significantly the observed charge distributions. Radial expansion velocities extracted from these calculations follow the systematics of Au1Au collisions. @S0556-2813~97!50205-6#

TL;DR: Experimental evidence for a long-range protein-protein interaction in purple membrane (PM) is presented and the effective spring constant for the interaction between neighboring protein trimers is determined to be k = 53 N/m.
Abstract: We present experimental evidence for a long-range protein-protein interaction in purple membrane (PM). The interprotein dynamics were quantified by measuring the spectrum of the acoustic phonons in the 2D bacteriorhodopsin (BR) protein lattice using inelastic neutron scattering. Phonon energies of about 1 meV were determined. The data are compared to an analytical model, and the effective spring constant for the interaction between neighboring protein trimers are determined to be k ¼ 53 N=m. Additional, optical-like excitations at 0.45 meV were found and assigned to intraprotein dynamics between neighboring BR monomers.

TL;DR: Examination of in vitro responses to a model environmental carcinogen of six non-tumor skin fibroblast strains from HCMM/DNS patients representing five families points to a metabolic anomaly which may contribute to the carcinogenic risk of the melanoma prone preneoplastic state presented by some DNS patients.
Abstract: The dysplastic nevus syndrome (DNS) is a preneoplastic melanocyte abnormality which occurs in families affected by hereditary cutaneous malignant melanoma (HCMM). A putative role of host-environmental interactions in the etiology of hereditary melanoma has been strengthened by the recent finding that fibroblasts derived from HCMM/DNS patients demonstrated enhanced sensitivity to u.v.-irradiation in vitro. We report here an extension of these studies in which we have examined the in vitro responses to a model environmental carcinogen, 4-nitroquinoline 1-oxide (4NQO), of six non-tumor skin fibroblast strains from HCMM/DNS patients representing five families. Three of the six HCMM/DNS strains showed enhanced cell killing with sensitivities greater than that of a xeroderma pigmentosum (XP) variant strain but less than those of ataxia telangiectasia and XP Group D cell strains. The inhibition and recovery of de novo DNA synthesis, together with the expression of repair synthesis, following 4NQO exposure appeared to be normal in HCMM/DNS strains, irrespective of their subsequent clonogenic potential. Our data point to a metabolic anomaly which may contribute to the carcinogenic risk of the melanoma prone preneoplastic state presented by some DNS patients.
