An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Polaritonic modes in a dense cloud of atoms

, 2015
We analyze resonant light scattering by an atomic cloud in a regime where near-field interactions between scatterers cannot be neglected. We first use a microscopic approach and calculate numerically the eigenmodes of the cloud for many different ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

First-principles study on the effective masses of zinc-blend-derived Cu_2Zn-IV-VI_4 (IV = Sn, Ge, Si and VI = S, Se)

, 2012
The electron and hole effective masses of kesterite (KS) and stannite (ST) structured Cu_2Zn-IV-VI_4 (IV = Sn, Ge, Si and VI = S, Se) semiconductors are systematically studied using first-principles calculations.

Entangled-State Cycles of Atomic Collective-Spin States [PDF]

, 1995
We study quantum trajectories of collective atomic spin states of $N$ effective two-level atoms driven with laser and cavity fields. We show that interesting ``entangled-state cycles'' arise probabilistically when the (Raman) transition rates between the

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Impact of high BaO content on tuning the structural, optical and radiation shielding properties of multicomponent borate glasses

Journal of Science: Advanced Materials and Devices
The impact of increasing BaO concentration on the B2O3-CaO-ZnO-BaO-Er2O3 glass samples' properties has been examined. The increase in density and molar volume is observed. FTIR analysis reveals the disruption of borate units and the creation of NBOs with

Effective atomic numbers of some composite mixtures including borax

Annals of Nuclear Energy, 2010
Abstract Effective atomic numbers for (PbO and Na 2 B 4 O 7 10H 2 O) and (UO 2 (NO 3 ) 2 , and Na 2 B 4 O 7 10H 2 O) mixtures against changing contents of PbO, Na 2 B 4 O 7 10H 2 O, and UO 2 (NO 3 ) 2 were measured in the X-ray energy range from 25.0 to 58.0 keV.
