Hand Swelling and Other Non–Raynaud Phenomenon Symptoms as the Initial Presentation of Systemic Sclerosis: Prevalence and Clinical Associations in Two US Cohorts

Arthritis &Rheumatology, EarlyView.
Objective Raynaud phenomenon (RP) is often the initial clinical manifestation of systemic sclerosis (SSc), but some patients develop other manifestations first. To help elucidate the diversity of SSc presentation in its early stages, we describe the initial clinical manifestations and antinuclear antibody (ANA) profiles of patients in two early SSc ...

Green Extraction and Fractionation of Chestnut Wood Waste: A Sustainable Pathway to Biopolymers and Antimicrobial Solutions

ChemSusChem, EarlyView.
A sustainable valorization of chestnut wood waste is proposed through microwave‐assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin‐rich fraction, used to synthesize a PVA‐based biopolymer ...

Haplotype‐resolved genome and pan‐genome graphs reveal the impacts of structural variation on functional genome and feather colors in chickens

iMetaOmics, EarlyView.
This study built a Wenchang chicken haplotype genome and integrated it with 29 others to create a chicken pangenome atlas. Analysis of 354 chickens revealed 185,205 structural variations (SVs), with one‐third derived from homology‐based and transposable elements.
