The development and validation of a new diagnostic sonographic enthesitis score for psoriatic arthritis: Diagnostic Ultrasound Enthesitis Tool (DUET)

Arthritis &Rheumatology, Accepted Article.
Objective The Diagnostic Ultrasound Enthesitis Tool (DUET) study aimed to develop and validate a new sonographic scoring system for enthesitis to aid PsA diagnosis. Methods We prospectively enrolled patients with early PsA, psoriasis without arthritis (PsO), and non‐inflammatory musculoskeletal symptoms as controls (CTL) from 17 centers. A standardized

Recurrent and synchronous insect pest outbreaks in forests [PDF]

Theoretical Population Biology, 2012
A minimal model for the interactions of trees, insects, and their enemies suggests a simple formula for splitting all forests where insect outbreaks can occur into two categories: where outbreaks are periodic and endogenously generated and where outbreaks are triggered by exogenous factors and are, in general, recurrent but aperiodic. The formula is in

Ant Diversity of the Xisha Islands: Community Structure, Exotic Species Colonization, and Ecological Functions in a Tropical Coral Archipelago

Biological Diversity, EarlyView.
The first inventory of ants from the Xisha Islands of the South China Sea was compiled, revealing 21 species: 70% native and 30% exotic. Anthropogenic disturbance primarily drove exotic colonization, whereas island area showed weak positive effects on species richness. Most ants were omnivorous, with key mutualistic and seed‐dispersal roles.

The Transcription Factor VdHapX Controls Iron Homeostasis and Is Crucial for Virulence in the Vascular Pathogen Verticillium dahliae

mSphere, 2018
Iron homeostasis is essential for full virulence and viability in many pathogenic fungi. Here, we showed that the bZip transcription factor VdHapX functions as a key regulator of iron homeostasis for adaptation to iron-depleted and iron-excess conditions

Life Forms and Mycorrhizal Types Shape Resource‐Use Strategies Reflected by Different Functional Traits in Woody Plants of the Qinling Mountains

Biological Diversity, EarlyView.
Both life forms and mycorrhizal symbioses shape plant functional trait divergence, revealing divergent resource‐use strategies across woody species in temperate forests. ABSTRACT Plant functional traits are influenced by both mycorrhizal types and life forms, yet the interactive effects of these two factors on functional trait regulation remain poorly ...
