Global existence for a go-or-grow multiscale model for tumor invasion with therapy

open access: yes, 2016
We investigate a PDE–ODE system describing cancer cell invasion in a tissue network. The model is an extension of the multiscale setting in [G. Meral, C. Stinner and C.

The power of microRNA regulation—insights into immunity and metabolism

open access: yesFEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Existe realmente o aquecimento global?

open access: yesResearch, Society and Development, 2022
A influência da temperatura nos organismos é um dos aspectos essenciais para a regulação e manutenção da vida. Ao longo do tempo geológico a temperatura na Terra oscilou entre extremos, como consequência de fenômenos geológicos naturais. Porém, especialmente a partir do século XX, algumas atividades antrópicas estão alterando o clima, ocasionando ...

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Local and global existence theorems for the Einstein equations [PDF]

open access: yesLiving Reviews in Relativity, 1998
This article is a guide to the literature on existence theorems for the Einstein equations which also draws attention to open problems in the field. The local in time Cauchy problem, which is relatively well understood, is treated first. Next global results for solutions with symmetry are discussed.

Global existence results for nonlinear Schrodinger equations with quadratic potentials [PDF]

open access: yes, 2004
We prove that no finite time blow up can occur for nonlinear Schroedinger equations with quadratic potentials, provided that the potential has a sufficiently strong repulsive component.

Coercivity and stability results for an extended Navier-Stokes system

open access: yes, 2012
In this article we study a system of equations that is known to {\em extend} Navier-Stokes dynamics in a well-posed manner to velocity fields that are not necessarily divergence-free. Our aim is to contribute to an understanding of the role of divergence
