Reversible addition-fragmentation chain transfer (RAFT) polymerization is one of the most common controlled techniques to prepare well-defined, rather narrow dispersed polymers due reduced demands in reactant preparation. Despite these advantages, RAFT was so far primarily utilized on small laboratory scales. This study presents a first step scaled-up by developing and experimentally validating...

Using aqueous emulsion as the medium in radiation-induced graft polymerization (RIGP) offers an environment-friendly shift from organic solvents while increasing efficiency through known water radiolysis-based initiation. In present paper, we further extend applicability of RIGP under influence reversible addition fragmentation chain transfer (RAFT) mechanisms. Emulsions prepared with Tween 20 ...

To better understand the characteristics of seismic response nuclear power stations with fixed-base and pile-raft foundations, a series shaking table tests were performed. The included three cases: free-field soil, structure without superstructure foundation embedded in soil. One white noise excitation earthquake motions different intensity selected as ground motion to identify structure, raft,...

During the past decade, the lipid-raft hypothesis has focused attention on the role of membrane domains in controlling cellular functions. Among the best-studied roles of lipid rafts is the regulation of T-cell signalling. In particular, a model has emerged in which lipid rafts regulate protein-protein interactions during signalling in a cholesterol-dependent manner. Does this model provide the...

We examined the distribution of selected raft proteins on the sarcolemma of skeletal myofibers and the role of cholesterol environment in the distribution. Immunofluorescence staining showed that flotillin-1 and influenza hemagglutinin exhibited rafts that located in the domains deficient of the dystrophin glycoprotein complex, but the distribution patterns of the two proteins were different. C...

BACKGROUND Although tissue perfusion is often decreased in patients with sepsis, the relationship between macrohemodynamics and microcirculatory blood flow is poorly understood. We hypothesized that alterations in retinal blood flow visualized by angiography may be related to macrohemodynamics, inflammatory mediators, and retinal microcirculatory changes. METHODS Retinal fluorescein angiograp...

Miniemulsion polymerization technique has been used extensively for preparing small sized uniform particles of polymers, core-shell polymer particles, hybrid particles and encapsulation of liquid core. The technique has achieved limited success in the area of uniform core shell structure with liquid as core, as it requires matching of strict thermodynamic and kinetic factors. The interfacial te...

A higher-order sandwich theory is implemented in conjunction with an equivalent mobility-based power flow progressive method to determine power flow for a sandwich configured floating raft vibration isolation system. The power spectrum changes in whole frequency range effectively when core materials’ properties change. It is also shown that the loss factors of the sandwich configured floating r...

The serine protease plasmin can efficiently degrade amyloid peptide in vitro, and is found at low levels in the hippocampus of patients with Alzheimer's disease (AD). The cause of such paucity remains unknown. We show here that the levels of total brain plasminogen and plasminogen-binding molecules are normal in these brain samples, yet plasminogen membrane binding is greatly reduced. Biochemic...

HIV-1 Vpu antagonizes the block to particle release mediated by CD317 (BST-2/HM1.24/Tetherin) via incompletely understood mechanisms. Vpu and CD317 partially reside in cholesterol-rich lipid rafts where HIV-1 budding preferentially occurs. Here we find that lipid raft association of ectopically expressed or endogenous CD317 was unaltered upon co-expression with Vpu or following HIV-1 infection....
