FEBS Letters, EarlyView.The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Le modèle VitiTerroir pour simuler la dynamique spatiale des vignobles sur le temps long (1836-2014)
Cybergeo, 2018 The VitiTerroir project ambitions to develop a model simulating spatial dynamics of vineyards in Centre-Val de Loire region, France. We study these dynamics in the long (several centuries), medium and short term, using historical sources (administrative ...

A Consensus Control for a Multi-Agent System With Unknown Time-Varying Communication Delays
IEEE Access, 2021 A multi-agent system to have information flow among agents is bound to experience a communication delay over a directed graph. However, delay information is often unavailable and time varying.

Characteristics of a Delayed System with Time-dependent Delay Time [PDF]
, 2004 The characteristics of a time-delayed system with time-dependent delay time is investigated. We demonstrate the nonlinearity characteristics of the time-delayed system are significantly changed depending on the properties of time-dependent delay time and especially that the reconstructed phase trajectory of the system is not collapsed into simple ...

Analytical solution of the fractional linear time-delay systems and their Ulam-Hyers stability [PDF]
arXiv, 2022 We introduce the delayed Mittag-Leffler type matrix functions, delayed fractional cosine, delayed fractional sine and use the Laplace transform to obtain an analytical solution to the IVP for a Hilfer type fractional linear time-delay system $D_{0,t}^{\mu,\nu}z\left( t\right) +Az\left( t\right) +\Omega z\left( t-h\right) =f\left( t\right) $ of order $1<

FEBS Letters, EarlyView.Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

Time-delayed feedback in neurosystems [PDF]
, 2008 The influence of time delay in systems of two coupled excitable neurons is studied in the framework of the FitzHugh-Nagumo model. Time-delay can occur in the coupling between neurons or in a self-feedback loop. The stochastic synchronization of instantaneously coupled neurons under the influence of white noise can be deliberately controlled by local ...

Families of periodic delay orbits [PDF]
arXiv, 2023 We construct and analyze families of periodic delay orbits for a class of delay differential equations in two dimensions depending on two real-valued functions. These families are parametrized by the delay parameter. It is possible to represent the dependency of these periodic delay orbits on the delay parameter by a curve in the plane, without loss of
