Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

[SPA] EL VIAJE DE RAFAEL HITLODEO: LA ESCRITURA DE UTOPÍA EN SU CONTEXTO // THE JOURNEY OF RAPHAEL HYTHLODAEUS: THE WRITING OF UTOPIA IN ITS CONTEXT

Los Libros de la Corte.es, 2018
En la primera traducción castellana de Utopía, realizada en 1637, no se publicó el prólogo de Rafael Hitlodeo al libro primero. En dicho texto se mencionan sucesos acaecidos en los meses que preceden a la muerte de Fernando el Católico.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Low-Cost Spinning Disk Confocal Microscopy with a 25-Megapixel Camera

Sensors
Spinning disk confocal microscopy enables fast optical sectioning with low phototoxicity but is often inaccessible due to high hardware costs. We present a lower-cost solution using a 25-megapixel machine vision CMOS camera and a custom-built spinning ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Assembling La nueva novela: Juan Luis Martínez and a Material Poetics of Relation

Latin American Research Review, 2017
This article considers 'La nueva novela', a strange book-object assembled by twentieth-century Chilean poet Juan Luis Martínez, in light of Édouard Glissant’s “poetics of relation” and Manuel DeLanda’s elaboration of “assemblage theory.” By bringing ...

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Re/position? "Tres Marías y una Rosa" three decades to address the resistance

Revista Chilena de Literatura, 2010
The present work explores the conditions and repercussions of staging anew an emblematic play of the dictatorship era in Chile: "Tres Marías y una Rosa," three decades after that period, and without significant modifications.
