FEBS Open Bio, EarlyView.This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Multiple solutions for parametric weighted (p,q)-equations
Electronic Journal of Differential EquationsIn this article, we prove that equations driven by a weighted (p,q)-Laplacian have at least two positive solutions, two negative solutions, and two sign-changing solutions.

FEBS Open Bio, EarlyView.Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Symmetries, travelling-wave and self-similar solutions of two-component BKP hierarchy
Alexandria Engineering JournalWe investigate the two-component BKP hierarchy equation for its Lie point symmetries. To obtain a complete classification of the group-invariant solution, we derive the one-dimensional optimal system of subalgebras of A3,3(D⨂sT2).

FEBS 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‐

Multiple symmetric solutions for a singular semilinear elliptic problem with critical exponent
Electronic Journal of Differential Equations, 2012 Let be $Gamma$ a closed subgroup of $O(N)$. We consider the semilinear elliptic problem $$displaylines{ -Delta u-frac{b(x)}{| x|^2}u-a(x)u=f(x)| u|^{2^{ast }-2}uquad hbox{in }Omega ,cr u=0 quadhbox{on } partial Omega , }$$ where $Omega subset ...

The role of lipid metabolism in neuronal senescence
FEBS Open Bio, EarlyView.Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

EXACT SOLUTION FOR FLAT SCALE-INVARIANT COSMOLOGY
Revista Mexicana de Astronomía y Astrofísica, 2019 An exact solution for the spatially flat scale-invariant cosmology, recently proposed by Maeder (2017a) is deduced. No deviation from the numerical solution was detected. The exact solution yields transparency for the dynamical equations, and faster cosmological constraints may be performed.
