Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

Ecography, EarlyView.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...

Regeneration failure, fire, topography, and climate interact to drive temperate wet forest landscapes into fire traps

Ecography, EarlyView.
Where early successional forests are more flammable than old‐growth forests, forested landscapes are vulnerable to shifting into ‘fire traps' through positive feedbacks, where fire leads to more fire. These feedbacks are amplified by increased flammability driven by climate change, the presence of non‐native flammable plant species, and slowed ...

Multivariate linear regression to predict association of non‐invasive arterial stiffness with cardiovascular events

ESC Heart Failure, Volume 12, Issue 2, Page 1141-1150, April 2025.
Abstract Background Arterial stiffness is a crucial factor in determining an increase in systolic blood pressure and pulse pressure and can also predict the development of cardiovascular disease (CVD). The purpose of this study was to examine the relationship between arterial stiffness and future CVD.

Unique Bioactive Secondary Metabolites of Ferns and Their Enhancement by Abiotic Stress: Medicinal Potential and Future Perspectives

Molecules
Ferns represent an evolutionarily distinct group of vascular plants and constitute an underexplored source of structurally diverse secondary metabolites with potential medicinal value. Several fern-derived compounds, including sesquiterpenes, triterpenes,

Squalene Cyclases and Cycloartenol Synthases from Polystichum polyblepharum and Six Allied Ferns

Molecules, 2018
Ferns are the most primitive of all vascular plants. One of the characteristics distinguishing them from flowering plants is its triterpene metabolism. Most cyclic triterpenes in ferns are hydrocarbons derived from the direct cyclization of squalene by ...

Beta Human Papillomaviruses Seropositivity and the Association With Cutaneous Squamous Cell Carcinoma—A Systematic Review and Meta‐Analysis

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Cutaneous squamous cell carcinoma (cSCC) is one of the most common nonmelanoma skin cancers, with increasing incidence globally. Beta genus human papillomaviruses (β‐HPVs), particularly in immunocompromised individuals, have been implicated in the development of cSCC. However, the strength of association between β‐HPV seropositivity
