The Fluorescent Amyloid Ligand X34 Binding to Transthyretin (TTR) Tetramer and Fibrils: FRET and Binding Constants of a Sequential Two‐step Process

ChemPhotoChem, Volume 9, Issue 2, February 2025.
A secret of life is molecular recognition; the ability of one molecule to recognize another through weak bonding interactions. Here we investigate a fluorescent amyloid ligand X34 and its binding propensity to two apparently asymmetric binding sites of the amyloidogenic plasma protein transthyretin (TTR), both in its native tetrameric form and as an ...

Beyond simplistic narratives: Dynamic farmers, precarity and the politics of agribusiness expansion

Journal of Agrarian Change, Volume 24, Issue 4, October 2024.
Abstract Agribusiness expansion is usually framed around two competing narratives. On the one hand, advocates present it as a promising vehicle to modernise agriculture and integrate small farmers into global value chains. On the other hand, critics denounce it as a top‐down corporate assault to monopolise agriculture and dispossess peasants of land ...

Amyloid beta 1‐40 and 1‐42 fibril ratios and maturation level cause conformational differences with minimal impact on autophagy and cytotoxicity

Journal of Neurochemistry, Volume 168, Issue 9, Page 3308-3322, September 2024.
The amyloid β (Aβ) peptide varies in length between 37 and 49 amino acids, with Aβ1‐42 being the most disease‐related and forms plaques in Alzheimer's disease. Aβ1‐40 also forms plaques and intertwines with Aβ1‐42, but their combined effect is still not clearly understood. Here, we fibrillized different Aβ1‐40:42 ratios and characterized both early and

Competitive integration models in the Western hemisphere: competitive leadership or mutual denial?

Revista CIDOB d'Afers Internacionals, 2013
The North Atlantic space is undergoing active reconfiguration. In the Western Hemisphere this trend is marked by the presence of three distinct models of integration: intra-regional blocks such as Mercosur and the Andean Community; the FTAA and mega ...

Amino‐Acid Side‐Chain Nanoarchitectonics for Tuning the Chiroptical Properties and Supramolecular Structure of Pentameric Oligothiophenes

ChemPhotoChem, Volume 8, Issue 7, July 2024.
Self‐assembled Proteophenes. Oligothiophenes with distinct amino acid side‐chain functionalities along the conjugated backbone displayed distinct chiroptical and structural properties in acidic or alkaline solutions. The distinct photophysical characteristics, as well as the supramolecular structures of the assemblies were highly influenced by the ...

Limitations of the knee society score in kinematically aligned total knee arthroplasty

Journal of Experimental Orthopaedics, Volume 11, Issue 3, July 2024.
Abstract Purpose The Knee Society Scoring System (KSS) is a frequently used outcome score which quantifies functional patients' outcomes before and after total knee arthroplasty (TKA). Several problems arise when trying to implement KSS for obtaining postoperative outcomes after more personalised aligned TKAs. Scoring for valgus femorotibial angle (FTA)
