Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Prebiotics in food and dietary supplements: a roadmap to EU health claims

open access: yesGut Microbes
Numerous studies have established that prebiotic ingredients in foods and dietary supplements may play a role in supporting human health. Over the three decades that have passed since prebiotics were first defined as a concept, research has revealed a ...

Assessing the possibility of prevention, treatment and correction of the intestinal microflora dysbiotic disorders in experimental pseudotuberculosis

open access: yesЖурнал инфектологии, 2014
The possibility was studied of preventing the development of pseudotuberculosis and correcting the dysbiotic disorders of the intestinal microflora in conventional white mice with prebiotic «Stimbifid» and exometabolites in supernatant fluids of native ...

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

Mirror symmetry breaking with limited enantioselective autocatalysis and temperature gradients: a stability survey

open access: yes, 2012
We analyze limited enantioselective (LES) autocatalysis in a temperature gradient and with internal flow/recycling of hot and cold material. Microreversibility forbids broken mirror symmetry for LES in the presence of a temperature gradient alone.

Chemical engineering as an essential element of industrial biotechnology in Mexico: New aims in research and university education

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract On the centennial of higher education in Chemical Engineering in Mexico, it is pertinent to revisit the key stages that have contributed to its consolidation as a vital discipline for the nation's scientific and technological advancement. Although the initial mission of chemical engineering education was primarily oriented toward the training ...

Prebiotic Homochirality as a Critical Phenomenon

open access: yes, 2005
The development of prebiotic homochirality on early-Earth or another planetary platform may be viewed as a critical phenomenon. It is shown, in the context of spatio-temporal polymerization reaction networks, that environmental effects -- be them ...

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Reduced alphabet of prebiotic amino acids optimally encodes the conformational space of diverse extant protein folds

open access: yesBMC Evolutionary Biology, 2019
Background There is wide agreement that only a subset of the twenty standard amino acids existed prebiotically in sufficient concentrations to form functional polypeptides.
