Self‐Assembly of Chiro‐Optical Materials from Nonchiral Oligothiophene‐Porphyrin Derivatives and Random Coil Synthetic Peptides

ChemPlusChem, Volume 88, Issue 1, January 2023., 2023
Chiral construction: By mixing anionic oligothiophene−porphyrin derivatives and cationic synthetic peptides, self‐assembled optoelectronic materials with distinct photo‐physical properties and specific architectonical arrangement can be afforded. The chemical composition of the oligothiophene−porphyrin derivative, as well as the sequence of the peptide,

The Key Architects of Brazil's Foreign Policy and the Quest for Multipolarity Under Lula

Bulletin of Latin American Research, Volume 45, Issue 2, April 2026.
ABSTRACT This article analyses the trajectories and worldviews of three central architects of Brazilian foreign policy during Lula's first two terms—Marco Aurélio Garcia, Samuel Pinheiro Guimarães and Celso Amorim. It argues that their progressive and anti‐imperialist orientations, aligned with the Workers' Party's broader project, were decisive in ...

Globalisation, regionalisation & the Americas. The free trade area of the Americas: fuelling the 'race to the bottom'? [PDF]

, 2005
The framing of the Free Trade Area of the Americas (FTAA) over a period of ten years is a project on a unique scale and with a unique significance. According to Robert Devlin, the FTAA is undoubtedly the most ambitious collective economic initiative in ...

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 ...

Brazil and the institutionalization of South America: from hemispheric estrangement to cooperative hegemony

Revista Brasileira de Política Internacional, 2011
This article argues that Brazil went from a posture of estrangement in relation to the hemispheric project represented by the Free Trade Area of the Americas (FTAA) to a strategy of cooperative hegemony aimed at institutionalizing the South American ...

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
