The absolute value of functions

open access: yes, 1999
Let \(X\) be a topological space and \(f\) be a real valued function defined on a subset of \(X\). We say that \(f\) is absolutely polynomial if there exist continuous functions \(g_0, \dots g_n\) defined on \(X\) such that \( |f(x)|= \sum _{k=0}^{n} g_k(x)f(x)^k \) for all \(x\) in the domain of \(f\). The authors study this notion for \(X = \mathbb R\

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Algebraic values of G-functions.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1993
It is a well-known fact that functions like \(\log z\) and \(\exp z\) assume transcendental values at non-zero algebraic points. This has been proved for a large class of functions satisfying linear differential equations with polynomial coefficients. Surprisingly, J.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
