β-Amyloid Monomers Are Neuroprotective [PDF]
The Journal of Neuroscience, 2009 The 42-aa-long β-amyloid protein—Aβ1-42—is thought to play a central role in the pathogenesis of Alzheimer's disease (AD) (Walsh and Selkoe, 2007). Data from AD brain (Shankar et al., 2008), transgenic APP (amyloid precursor protein)-overexpressing mice (Lesné et al., 2006), and neuronal cultures treated with synthetic Aβ peptides (Lambert et al., 1998)

Decay of correlations in the monomer-dimer model [PDF]
arXiv, 2023 We consider the monomer-dimer model, whose realisations are spanning sub-graphs of a given graph such that every vertex has degree zero or one. The measure depends on a parameter, the monomer activity, which rewards the total number of monomers. We consider general correlation functions including monomer-monomer correlations and dimer-dimer covariances.

Phase directed excitonic transport and its limitations due to environmental influence [PDF]
Chem. Phys. 379, 33 (2011), 2010 We investigate theoretically the transfer of excitation along a one dimensional chain of monomers for a situation in which initially the excitation is shared coherently by two monomers. We show that depending on the relative phase between the two monomers strong directionality of the energy transfer is possible.

1,4-Phenylene diallyl bis(carbonate)
IUCrData, 2023 The title molecule, C14H14O6, is based on a benzene core di-substituted by allyl carbonate groups in the para positions. The molecule is placed on an inversion centre, and the substituents are twisted with respect to the central benzene ring plane.

Symmetry-breaking in chiral polymerisation [PDF]
, 2004 We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
