Macropinocytosis, a fluid-phase endocytosis, is a crucial pathway for antigen uptake and presentation in macrophages. We attempted to characterise the activation and deactivation of a small GTPase molecular switch, Rac1, in macropinocytosis using microscopic photo-manipulation. Expression of genetically encoded photoactivatable-Rac1 (PA-Rac1) in RAW264 macrophages enabled the local, reversible ...

Protein kinase B/Akt possesses prosurvival and antiapoptotic activities and is involved in growth factor-mediated neuronal protection. In this study we establish Akt deactivation as a causal mediator of cell death. Akt deactivation occurs in multiple models of cell death including N-methyl-d-aspartate excitotoxicity, vascular stroke, and nitric oxide (NO)- and hydrogen peroxide (H2O2)-elicited ...

The absolute fluorescence quantum yield (Φfl) of a polyfluorenyl azomethine homopolymer was measured as a function of solvent polarity. The solvent induced and temperature dependent fluorescence of the homopolymer were also investigated and they were compared to the corresponding monomer and copolymer. The Φfl of the homopolymer was consistent (45-70%), regardless of solvent polarity with Stoke...

Mobile Adhoc Networks (MANETs) are networks designed to operate in volatile and rapidly changing environments. Nodes within these networks are intended to be freeroaming, self-organising, self-discovering and operate where dedicated infrastructure is either not present or only ephemerally available. Within such environments, resource-limited nodes are expected to make complex risk-based decisio...

The massive consumption of fossil fuels and associated environmental issues are leading to an increased interest in alternative resources such as biofuels. The renewable biofuels can be upgraded from bio-oils that are derived from biomass pyrolysis. Catalytic cracking and hydrodeoxygenation (HDO) are two of the most promising bio-oil upgrading processes for biofuel production. Heterogeneous cat...

While the existence of the trough effect is unquestioned, its theoretical significance is unknown. A multifaceted instrumental approach - spectrographic, cineradiographic, and vocal tract modeling - was used to document the trough effect in open (V.CV) and closed (VC.V) syllable forms using a symmetrical vowel context surrounding labial stops. Collectively, the results document the trough pheno...

The modeling, simulation, and dynamic optimization of an industrial reaction system for acetylene hydrogenation are discussed in the present work. The process consists of three adiabatic fixed-bed reactors, in series, with interstage cooling. These reactors are located after the compression and the caustic scrubbing sections of an ethylene plant, characterizing a front-end system; in contrast t...
