Recombination-aware phylogenetic analysis sheds light on the evolutionary origin of SARS-CoV-2

Scientific Reports
SARS-CoV-2 can infect human cells through the recognition of the human angiotensin-converting enzyme 2 receptor. This affinity is given by six amino acid residues located in the variable loop of the receptor binding domain (RBD) within the Spike protein.

Variação sazonal do fluxo de calor no solo dentro de um manguezal tropical Seazonal variation of soil heat flux within tropical mangrove

Revista Brasileira de Engenharia Agrícola e Ambiental, 2010
Os manguezais são ecossistemas de grande importância em virtude da sua biodiversidade, embora ainda pouco estudados. O fluxo de calor no solo (FCS) é uma propriedade que interfere no microclima de um ecossistema e depende de vários fatores.

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Heat shock transcription factor-mediated thermal tolerance and cell size plasticity in marine diatoms

Nature Communications
Diatoms are a crucial component of marine ecosystems, recognized for their broad environmental adaptability and wide temperature tolerance. However, the molecular mechanisms underlying their adaptability to diverse temperatures are unknown. In this study,

Integrative Omics Analysis Reveals the Regulation of Hypoxia Tolerance in Large Yellow Croaker (Larimichthys crocea) via the Lipoic Acid Synthase (lias) Gene

Advanced Science, EarlyView.
Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the

A Pathology‐Instructed Theranostic Platform with Mechanoadaptive and ROS‐Powered Nanobreathing Functions for Precision Myocardial Repair

Advanced Science, EarlyView.
We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

Advanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.
