Non-radial normalized solutions for a nonlinear Schrodinger equation
Electronic Journal of Differential Equations, 2023 This article concerns the existence of multiple non-radial positive solutions of the L2-constrained problem $$\displaylines{-\Delta{u}-Q(\varepsilon x)|u|^{p-2}u=\lambda{u},\quad \text{in }\mathbb{R}^N, \\ \int_{\mathbb{R}^N}|u|^2dx=1,}$$ where \(Q(x)\)

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Journal of Differential Equations, 2019 We deal with Dirichlet systems involving the mean curvature operator in Minkowski space M ( w ) = div ( ∇ w 1 − | ∇ w | 2 ) in a ball in R N . Using the fixed point index and the lower and upper solutions method, we first obtain the existence of positive

Multiple positive radial solutions for Neumann elliptic systems with gradient dependence [PDF]
Mathematical methods in the applied sciences, 2017 We provide new results on the existence, nonexistence, and multiplicity of nonnegative radial solutions for semilinear elliptic systems with Neumann boundary conditions on an annulus.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
