XC cells, derived from a Rous sarcoma virus-induced Wistar strain rat tumor, form syncytia when cultured in the presence of murine leukemia virus-producing mouse cells. However, one XC cell culture (designated as XC-v cells), found to produce type C virus particles, fails to form syncytia in the presence of murine leukemia virus-producing mouse cells. Coculture of XC-v cells and XC cells negati...

BACKGROUND The purpose of this observational study was to investigate the relationship between splanchnic and renal blood flow during infrarenal aortic cross-clamp (XC) and postoperative gastrointestinal perfusion and function. METHODS Descending aortic blood flow (DABF) was continuously monitored with an oesophageal Doppler monitor (Cardio-Q, Deltex Ltd, Chichester, UK) in 31 patients underg...

The effect of productive murine leukemia virus (MuLV) infection of the syncytium-forming property of XC cells was studied MuLV-Moloney-infected XC cells, designated XC(M), initially went through a period of spontaneous syncytium formation. The syncytia then disappeared, and XC(M) cells continued to propagate and produce both infectious MuLV and MuLV group-specific antigens. However, XC(M) cells...

The XC cell line undergoes extensive syncytium formation after infection with ecotropic murine leukemia viruses (MLVs) and is frequently used to titrate these viruses. This cell line is unique in its response to the ecotropic MLV envelope protein (Env) in that it undergoes syncytium formation with cells expressing Env protein containing R peptide (R(+) Env), which is known to suppress the fusog...

The exact exchange-correlation (xc) kernel ${f}_{\text{xc}}(x,{x}^{\ensuremath{'}},\ensuremath{\omega})$ of linear response time-dependent density functional theory is computed over a wide range frequencies for three canonical one-dimensional finite systems. Methods used to ensure the numerical robustness ${f}_{\text{xc}}$ are set out. frequency dependence found be largely due its analytic stru...

Holas and March [Phys. Rev. A. 51, 2040 (1995)] gave a formally exact theory for the exchange-correlation (xc) force F(xc)(r)= -inverted Deltaupsilon(xc)(r) associated with the xc potential upsilon(xc)(r) of the density-functional theory in terms of low-order density matrices. This is shown in the present study to lead, rather directly, to the determination of a sum rule nF(xc)=0 relating the x...

Inhibitors of endosome acidification or cathepsin proteases attenuated infections mediated by envelope proteins of xenotropic murine leukemia virus-related virus (XMRV) and Ebola virus, as well as ecotropic, amphotropic, polytropic, and xenotropic murine leukemia viruses (MLVs), indicating that infections by these viruses occur through acidic endosomes and require cathepsin proteases in the sus...

In the central nervous system, cystine import in exchange for glutamate through system xc- is critical for the production of the antioxidant glutathione by astrocytes, as well as the maintenance of extracellular glutamate. Therefore, regulation of system xc- activity affects multiple aspects of cellular physiology and may contribute to disease states. Pituitary adenylate cyclase-activating poly...

We propose an approach to approximate the exchange and correlation (XC) term in density functional theory. The XC potential is considered as an electrostatic potential, generated by a fictitious XC density, which is in turn a functional of the electronic density. We apply the approach to develop a correction scheme that fixes the asymptotic behavior of any approximated XC potential for finite s...
