Mathematical Modelling and Analysis, 2017 In this paper we study the problem of the diffusion of one substance through the pores of a porous multi layered material which may absorb and immobilize some of the diffusing substances with the evolution or absorption of heat. As an example we consider

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Upper bounds for the number of limit cycles of polynomial differential systems
Electronic Journal of Differential Equations, 2016 For $\varepsilon$ small we consider the number of limit cycles of the polynomial differential system $$ \dot{x}=y-f_1(x,y)y, \quad \dot{y}=-x-g_2(x,y)-f_2(x,y)y, $$ where $f_1(x,y)=\varepsilon f_{11}(x,y)+\varepsilon^2f_{12}(x,y)$, $g_2(x,y ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Direct integrals and spectral averaging [PDF]
, 2010 A one parameter family of selfadjoint operators gives rise to a corresponding direct integral. We show how to use the Putnam Kato theorem to obtain a new method for the proof of a spectral averaging ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Limit cycles for piecewise smooth perturbations of a cubic polynomial differential center
Electronic Journal of Differential Equations, 2015 In this article, we study the planar cubic polynomial differential system $$\displaylines{ \dot{x}=-yR(x,y)\cr \dot{y}=xR(x,y) }$$ where $R(x,y)=0$ is a conic and $R(0,0)\neq 0$.
