Phosphorylation as a Tool To Modulate Aggregation Propensity and To Predict Fibril Architecture
Authors: Valette Nathalie M. , Radford Sheena E. , Harris Sarah A. , Warriner Stuart L. 
Published: December 2011

AbstractDespite the importance of post‐translational modifications in controlling the solubility and conformational properties of proteins and peptides, precisely how the aggregation propensity of different peptide sequences is modulated by chemical modification remains unclear. Here we have investigated the effect of phosphorylation on the aggregation propensity of a 13‐residue synthetic peptide incorporating one or more phosphate groups at seven different sites at various pH values. Fibril formation was shown to be inhibited when a single phosphate group was introduced at all seven locations in the peptide sequence at pH 7.5, when the phosphate group is fully charged. By contrast, when the same peptides were analysed at pH 1.1, when the phosphate is fully protonated, fibrils from all seven peptide sequences form rapidly. At intermediate pH values (pH 3.6) when the phosphate group is mono‐anionic, the aggregation propensity of the peptides was found to be highly dependent on the position of the phosphate group in the peptide sequence. Using this information, combined with molecular dynamics (MD) simulations of the peptide sequence, we provide evidence consistent with the peptide forming amyloid fibrils with a class 7 architecture. The results highlight the potential utility of phosphorylation as a method of reversibly controlling the aggregation kinetics of peptide sequences both during and after synthesis. Moreover, by exploiting the ability of the phosphate group to adopt different charge states as a function of pH, and combining experimental insights with atomistic information calculated from MD simulations as pH is varied, we show how the resulting information can be used to predict fibril structures consistent with both datasets, and use these to rationalise their sensitivity of fibrillation kinetics both to the location of the phosphate group and its charge state.
Design Criteria for Oilfield Separators Improved by Computational Fluid Dynamics
Authors: Pourahmadi Laleh A. , Svrcek W. Y. , Monnery W. D. 
Published: December 2011

AbstractOilfield separator data ranging from light‐oil conditions to heavy‐oil conditions were incorporated into suitable two‐phase and three‐phase computational fluid dynamics (CFD) models to provide improved design criteria for separator design methods. The CFD simulation results revealed that the most important affecting parameters are vapor density and oil viscosity. In contrast with the classic design methods, noticeable residence times were required for liquid droplets to penetrate through the fluid interfaces. Moreover, it was indicated that the Abraham equation should be used instead of the Stokes' law in the liquid‐liquid separation calculations. The velocity constraints caused by re‐entrainment in horizontal separators were also studied and led to novel correlations.

SPARC‐like 1 (SC1) is a diversely expressed and developmentally regulated matricellular protein that does not compensate for the absence of SPARC in the CNS
Authors: Lloyd‐Burton Samantha , Roskams A. Jane 
Published: December 2011

AbstractSPARC‐like 1 (SC1) is a member of the SPARC family of matricellular proteins that has been implicated in the regulation of processes such as cell migration, proliferation, and differentiation. Here we show that SC1 exhibits remarkably diverse and dynamic expression in the developing and adult nervous system. During development, SC1 localizes to radial glia and pial‐derived structures, including the vasculature, choroid plexus, and pial membranes. SC1 is not downregulated in postnatal development, but its expression shifts to distinct time windows in subtypes of glia and neurons, including astrocytes, large projection neurons, Bergmann glia, Schwann cells, and ganglionic satellite cells. In addition, SC1 expression levels and patterns are not altered in the SPARC null mouse, suggesting that SC1 does not compensate for the absence of SPARC. We conclude that SC1 and SPARC may share significant homology, but are likely to have distinct but complementary roles in nervous system development. J. Comp.

Immunohistochemical study of the distribution of calcium binding proteins in the brain of a chondrostean (Acipenser baeri)
Authors: Graña Patricia , Huesa Gema , Anadón Ramón , Yáñez Julián 
Published: December 2011

AbstractChondrosteans represent an ancient lineage in ray‐finned bony fishes and hence in jawed vertebrates. This immunohistochemical study in the brain of the Siberian sturgeon reports the neuronal distribution of three cytosolic calcium‐binding proteins: calbindin‐D28k (CB), calretinin (CR), and parvalbumin (PV). CB and CR are widely expressed in different neuron subsets distributed throughout the sturgeon brain. Studies using double immunofluorescence reveal a wide co‐distribution of CB and CR in the brain nuclei but scarce co‐localization at cellular level. In the forebrain, CR‐ and CB‐immunoreactive (ir) populations were observed in the olfactory bulbs, in pallial and subpallial telencephalic areas, and in some diencephalic nuclei. CR‐ir cells were also observed in the posterior tubercle and CB‐ir cells in the preglomerular complex. At midbrain and hindbrain basal levels, CB‐ir and CR‐ir cell bodies were mainly distributed in periventricular areas. In the cerebellum, CB and CR cells were co‐localized in some granular cell subsets in laterodorsal and dorsolateral regions, and in some Purkinje‐like cells. CB‐ir and CR‐ir fibers were mainly observed in the olfactory bulbs, hypothalamus, and habenula, and in fiber tracts that coursed in the optic tectum and through the mesencephalic and rhombencephalic basal areas. With regard to PV, the sturgeon brain showed a rather limited distribution of PV‐ir perikarya and fibers. Thus, CR, CB, and PV allowed the identification of subpopulations of neurons not distinguished on the basis of cytoarchitecture alone, which provided a better understanding of the anatomical organization of the sturgeon brain. These results reveal numerous shared features with teleosts, but also important differences. J. Comp. Neurol. 520:2086–2122, 2012. © 2011 Wiley Periodicals, Inc.
