Transformative changes are needed to support socio-bioeconomies for people and ecosystems in the Amazon.

Current social-technical and political conditions threaten the integrity of the Amazon biome. Overcoming these lock-ins requires structural transformations away from conventional economies towards 'socio-bioeconomies' (SBEs). SBEs are economies based on the sustainable use and restoration of Amazonian ecosystems, as well as Indigenous and rural livelihood systems in the region.

Dietary Polyphenols against Oxidative Stress in Head and Neck Cancer: What's New, What's Next.

Head and neck cancers (HNC) are a worldwide health problem, accounting for over 5% of all types of cancers. Their varied nature makes it sometimes difficult to find clear explanations for the molecular mechanisms that underline their onset and development. While chemio- and radiotherapy are clearly not to be dismissed, we cannot undervalue the effect that polyphenols - especially dietary polyphenols - can have in helping us to cope with this medical emergency.

Natural Bioactive Compounds against Oxidative Stress: Dietary Polyphenols Strike Back.

Oxidative stress is a major cellular and metabolic burden that can really alter cell life and become the base for disease onset and development. Many widespread pathologies can develop from an unresolved oxidative stress situation; thus, addressing this state is paramount for human health. Our antioxidant enzymes sometimes are not just enough.

Equity, participation, and planning for recovery in Puerto Rico.

Based on a survey of stakeholders from 34 municipalitiesin Puerto Rico 1 year following HurricaneMaria, this study reports on progress and prioritiesfor longer-term recovery. Following a description ofthe storm and its impacts and an overview of recoveryprinciples, initial insights expressed after the stormare studied. Over 56 percent of respondents rankedthe need for equity considerations as the top recoverypriority, while 23 percent ranked building back faster,and 11 percent supported building back stronger as thetop priority.

Safety threshold of R-wave amplitudes in patients with implantable cardioverter defibrillator.

Objective: A safety threshold for baseline rhythm R-wave amplitudes during follow-up of implantable cardioverter defibrillators (ICD) has not been established. We aimed to analyse the amplitude distribution and undersensing rate during spontaneous episodes of ventricular fibrillation (VF), and define a safety amplitude threshold for baseline R-waves.

Methods: Data were obtained from an observational multicentre registry conducted at 48 centres in Spain.
