Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Die "unsichtbare Hand" in der Sprache. Eine kritische Betrachtung von Kellers Sprachwandeltheorie

open access: yesLinguistik Online, 2004
How is language change effected and how does it proceed? In this article the central concepts of Rudi Keller's much-quoted work "Sprachwandel: von der unsichtbaren Hand in der Sprache" ("On Language Change. The Invisible Hand in Language") are introduced

Gender, Sexuality, And Shifting Styles: Knowledge Production and Codifying Language Use in Style Guides

open access: yesEx Aequo: Revista da Associação Portuguesa de Estudos sobre as Mulheres
Recent sociopolitical movements concerning gender identity have shifted conversations about language use and meaning. Style guides reflect this shift, updating and expanding sections on inclusive language in newer editions, and codifying written ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

La toponymie orale comme témoignage d’une langue éteinte

open access: yesLa Bretagne Linguistique, 1987
It has been said that an extinct language still lives on in toponymy: we were thinking then of written toponymy which, it is true, is enough to give a colour, an aura to a region when it is very general, for example Cornwall or south-east Wales, where ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Light Verbs and Grammaticalization. Evidence From the Catalan Light Verb “Agafar”

open access: yesCatalan Journal of Linguistics
Determining the linguistic nature of light verbs – whether they are lexical or grammatical units – is still an open question. Light verbs are often characterised as delexicalized.
