An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

Cognitive and institutional barriers to effective natural resource management under global change

Conservation Biology, EarlyView.
Abstract Many of the most challenging decisions facing natural resource managers today can be understood as time dependent. The concept of time‐dependent decisions is useful when considering natural resource management decisions that are characterized by nonstationarity in the underlying ecological system, uncertainty surrounding key ecological ...

Building evolutionary resilience as a framework for managing safe haven populations

Conservation Biology, EarlyView.
Abstract Safe havens are widely used to mitigate the impacts of invasive predators on threatened species, yet their isolation often disrupts evolutionary processes and can leave these species vulnerable to environmental change and stochastic events.

Climate warming may erode thermal barriers to pest invasion in tropical alpine ecosystems: Evidence from the Andes

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract Climate warming is increasingly enabling species to cross bioclimatic barriers, driving altitudinal range expansions of species and facilitating biological invasions into ecosystems that were historically protected by low temperatures. Among these cold ecosystems are tropical alpine systems—páramos—found in the tropical Andes above 3000 m ...

Ultra‐Processed Food Consumption and Childhood Allergic Diseases: Increased Risk of Asthma Onset in the SENDO Project

Allergy, Volume 81, Issue 10, Page 3504-3514, October 2026.
The SENDO cohort study (2015–2024) prospectively analyzed the impact of ultra‐processed food (UPF) consumption on asthma and atopy in 1,546 Spanish children. Higher UPF intake (NOVA 4 classification) was significantly associated with an increased risk of asthma but not atopy, atopic dermatitis, neumoallergen sensitation, food allergy over five years ...
