Hydrological Connectivity and Local Environment Alternately Drive Spatial Structure of Floodplain Aquatic Community Across Seasons

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Our study shows that the landscape‐scale environmental gradient represented as ecotone and as local environmental factors can alternately determine the spatial structures of the floodplain biota across seasons. The study highlights the understudied yet important linkages of spatial and temporal biotic assemblages and advance understanding of ecology ...

Fat‐Free Mass: Friend or Foe to Metabolic Health?

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 1, February 2025.
ABSTRACT Background Fat mass (FM) and fat‐free mass (FFM) are body composition estimates commonly reported in research studies and clinical settings. Recently, fat‐free mass indexed to height (fat‐free mass index; FFMI) has been shown to be positively associated with impaired insulin sensitivity or insulin resistance.

Inhibition of EZH2 Promotes Human Embryonic Stem Cell Differentiation into Mesoderm by Reducing H3K27me3. [PDF]

open access: yes, 2017
Mesoderm derived from human embryonic stem cells (hESCs) is a major source of the mesenchymal stem/stromal cells (MSCs) that can differentiate into osteoblasts and chondrocytes for tissue regeneration.

Bivalent Inhibitor of the N-end Rule Pathway [PDF]

open access: yes, 1999
The N-end rule relates the in vivo half-life of a protein to the identity of its N-terminal residue. Ubr1p, the recognition (E3) component of the Saccharomyces cerevisiae N-end rule pathway, contains at least two substrate-binding sites.
