Iron Deficiency Impairs Muscle Stem Cell Proliferation and Skeletal Muscle Regeneration via HIF‐2α Stabilization

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 6, December 2025.
ABSTRACT Background Functional iron deficiency affects a large proportion of patients with chronic diseases and is increasingly observed in older adults. Clinical evidence links iron deficiency to sarcopenia, yet the mechanistic relationship between iron status and muscle regeneration remains poorly defined.

Prelamin A-mediated recruitment of SUN1 to the nuclear envelope directs nuclear positioning in human muscle [PDF]

open access: yesCell Death & Differentiation, 2011
Lamin A is a nuclear lamina constituent expressed in differentiated cells. Mutations in the LMNA gene cause several diseases, including muscular dystrophy and cardiomyopathy. Among the nuclear envelope partners of lamin A are Sad1 and UNC84 domain-containing protein 1 (SUN1) and Sad1 and UNC84 domain-containing protein 2 (SUN2), which mediate nucleo ...

Direct Measurements of Absolute Branching Fractions for D0 and D+ Inclusive Semimuonic Decays

open access: yes, 2008
By analyzing about 33 $\rm pb^{-1}$ data sample collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measure the branching fractions for the neutral and charged $D$ inclusive semimuonic decays to be $BF(D^0 \to \mu^

A novel function for the Caenorhabditis elegans torsin OOC-5 in nucleoporin localization and nuclear import. [PDF]

open access: yes, 2015
Torsin proteins are AAA+ ATPases that localize to the endoplasmic reticular/nuclear envelope (ER/NE) lumen. A mutation that markedly impairs torsinA function causes the CNS disorder DYT1 dystonia. Abnormalities of NE membranes have been linked to torsinA

Mechanical Signaling: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 6, Issue 12, December 2025.
In this review, we summarize cell–ECM interactions and delve into the complex mechanotransduction. We introduce advanced research methods and emerging clinical tools used to study cellular mechanical phenotypes, mechanotransduction, and disease progression. Additionally, we analyze the role of mechanical biomarkers in the development and progression of

Quantum spin models for the SU(n)1 Wess–Zumino–Witten model

open access: yesNuclear Physics B, 2014
We propose 1D and 2D lattice wave functions constructed from the SU(n)1 Wess–Zumino–Witten (WZW) model and derive their parent Hamiltonians. When all spins in the lattice transform under SU(n) fundamental representations, we obtain a two-body Hamiltonian

Experimental study of $\psi(2S)$ decays to $\K^+ K^- \pi^+ \pi^- \pi^0$ final states

open access: yes, 2006
$K^+K^-\pi^+\pi^-\pi^0$ final states are studied using a sample of $14\times10^6$ $\psi(2S)$ decays collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Position Collider.

Measurement of proton electromagnetic form factors in $e^+e^- \to p\bar{p}$ in the energy region 2.00-3.08 GeV

open access: yes, 2020
The process of $e^+e^- \rightarrow p\bar{p}$ is studied at 22 center-of-mass energy points ($\sqrt{s}$) from 2.00 to 3.08 GeV, exploiting 688.5~pb$^{-1}$ of data collected with the BESIII detector operating at the BEPCII collider. The Born cross section~(

Writing the Engram: Epigenetic Mechanisms of Memory Allocation

open access: yesJournal of Neurochemistry, Volume 169, Issue 12, December 2025.
Memory allocation refers to the selective recruitment of neurons to engram cells upon memory formation. While previous studies have documented the importance of intrinsic excitability and the transcription factor CREB on memory allocation, epigenetic mechanisms have remained poorly understood. Here, we summarise recent discoveries epigenetic mechanisms

Observation of the $\psi(1^3D_2)$ state in $e^+e^-\to\pi^+\pi^-\gamma\chi_{c1}$ at BESIII

open access: yes, 2015
We report the observation of the $X(3823)$ in the process $e^+e^-\to \pi^+\pi^-X(3823) \to \pi^+\pi^-\gamma\chi_{c1}$ with a statistical significance of $6.2\sigma$, in data samples at center-of-mass energies $\sqrt{s}=$4.230, 4.260, 4.360, 4.420 and 4 ...
