Neural progenitor cells (NPCs) of feline origin (cNPCs) have demonstrated utility in transplantation experiments, yet are difficult to grow in culture beyond the 1 month time frame. Here we use an enriched, serum-free base medium (Ultraculture) and report the successful long-term propagation of these cells. Primary cultures were derived from fetal brain tissue and passaged in DMEM/F12-based or ...

During lignocellulosic bioethanol production, the whole slurry obtained by steam explosion is filtered, generating a water-insoluble fraction rich in cellulose which used for saccharification and ethanol fermentation, as well liquid containing solubilised glucose xylose but also some inhibitory by-products (furan derivatives, weak acids phenols), limits its use this purpose. Since utilization o...

The genus Perkinsus includes protozoan parasites of mollusks responsible for losses in the aquaculture industry and hampering the recovery of natural shellfish beds worldwide, and they are a key taxon for understanding intracellular parasitism adaptations. The ability to propagate the parasite in liquid media, in the absence of the host, has been crucial for improving understanding of its biolo...

By performing a stochastic dynamic in a space of Slater determinants, the full configuration interaction quantum Monte Carlo (FCIQMC) method has been able to obtain energies which are essentially free from systematic error to the basis set correlation energy, within small and systematically improvable error bars. However, the weakly exponential scaling with basis size makes converging the energ...

With the aid of a highly specific murine monoclonal antibody, F12, an immunofluorescence method was elaborated that allowed sensitive and specific detection of the ganglioside antigen fucosyl-GM1 (IV2FucII3NeuAcGgOse4Cer) in different types of human lung cancer and normal tissues. Nineteen of 21 cases of small cell lung cancer were positive with the F12 immunofluorescence method as compared to ...

HIV-1 entry into cells is mediated by interactions between the envelope (Env) gp120 and gp41 proteins with CD4 and chemokine receptors via an intermediate called the viral fusion complex (vFC). Here, mAbs were used to find the dynamic changes in expression of antigenic epitopes during vFC formation. A CD4-specific mAb (R275) and anti-vFC mAbs, designated F12-1, F13-6 and F18-4 that recognize th...

Acrolein is a toxic combustion product that elicits apoptotic and/or necrotic cell death depending on the conditions under which exposure occurs. As a strong electrophile, side-reactions with nucleophilic media constituents seem likely to accompany study of its toxicity in vitro, but these reactions are poorly characterized. We have thus examined the effect of media composition on the toxicity ...

More than 70 unique micro-hydrated structures of pyrimidine, ranging in size from 1 to 7 water molecules, have been characterized with the B3LYP density functional and the 6-311++G(2df,2pd) triple-ζ split-valence basis set. Explicitly correlated MP2-F12 single-point computations were performed on each structure with a correlation consistent triple-ζ basis set to estimate the relative and dissoc...

It was previously shown that serum low density lipoprotein (LDL) binds to type I collagen gels and that the binding is increased after modification by cultured endothelial cells. It is now demonstrated that when LDL is incubated with cells cultured in Dulbecco's modified minimal essential medium (DMEM), the subsequent binding of LDL to collagen is considerably less than after incubation with en...
