Protocol for integrative transcriptomic/metabolomic analysis: A case study on factors influencing the oyster-POMS disease

Deciphering the molecular mechanisms underlying complex biological interactions requires comprehensive approaches that capture these interactions across multiple regulatory and functional levels. Here, we present a protocol applied to the host-pathogen-environment interactions un...

Local-to-global heating crossover in chains of nanomagnets: A two-scale analytical framework

We develop a two-scale analytical formalism to study heat generation and thermal transport in one-dimensional systems of nanomagnets subjected to a uniform alternating magnetic field. At the nanoscale, each nanomagnet acts as a localized, temperature-dependent heat source governe...

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate...

Multiomics reprogramming reverses disease susceptibility in Magallana gigas during aging

Aging is a progressive and irreversible biological process that typically increases susceptibility to infectious diseases. However, unexpectedly, the opposite outcome was observed in oysters: older oysters exhibit increased tolerance to Pacific oyster mortality syndrome (POMS), a...

Impact of living and training at low altitude for several years on endurance performance at higher altitude: Myth or reality

Abstract The physiological adaptations of long‐term high‐altitude residents without high‐altitude genetic ancestry remain poorly characterized. This study investigated whether permanent residence at low altitude (1200 m) influences performance at higher altitude (2500 m). We comp...

On the weak solvability of a class of variable exponent systems

Abstract We use a variational approach based on the mountain-pass theorem to prove the existence of weak solutions for nonlinear variable exponent systems with homogeneous Dirichlet boundary conditions. The class of systems discussed here is governed by Leray-Lions type operators...

Atmospheric forcing and ocean preconditioning for dense shelf water cascading in the northwestern Mediterranean

<title>Abstract</title> Dense shelf water cascading (DSWC) in the northwestern Mediterranean Sea occurs due to the densification and overflow of shelf water in winter. This process ventilates the deep basin with waters that can be denser than those generated by open-ocean convect...
