FEBS Letters, EarlyView.Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

Applications of Local Linking to Critical Point Theory
Journal of Mathematical Analysis and Applications, 1995 Let \(f\in C^1 (X, \mathbb{R})\) satisfy a local linking condition at 0, i.e. the Banach space \(X\) splits as \(X= X^1 \oplus X^2\), \(f(u) \geq 0\) for \(u\in X^1\), \(|u|\leq r\), and \(f(u)\leq 0\) for \(u\in X^2\), \(|u|\leq r\); for some \(r>0\).

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Periodic solutions to a class of distributed delay differential equations via variational methods
Advances in Nonlinear Analysis, 2023 In this article, we study the existence of periodic solutions to a class of distributed delay differential equations. We transform the search for periodic solutions with the special symmetry of a delay differential equation to the problem of finding ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment
FEBS Letters, EarlyView.The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Sign-changing solutions for some nonlinear problems with strong resonance
Boundary Value Problems, 2011 By means of critical point and index theories, we obtain the existence and multiplicity of sign-changing solutions for some elliptic problems with strong resonance at infinity, under weaker conditions.

Theory of the Many-Body Localization Transition in One-Dimensional Systems
Physical Review X, 2015 We formulate a theory of the many-body localization transition based on a novel real-space renormalization group (RG) approach. The results of this theory are corroborated and intuitively explained with a phenomenological effective description of the ...

A working model for cytoplasmic assembly of H/ACA snoRNPs
FEBS Letters, EarlyView.Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Sing-changing solutions for nonlinear problems with strong resonance
Electronic Journal of Differential Equations, 2012 Using critical point theory and index theory, we prove the existence and multiplicity of sign-changing solutions for some elliptic problems with strong resonance at infinity, under weaker conditions than in the references.
