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.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Dizhen xuebao快速准确地计算走时和射线路径是实现地震成像和反演的关键。在各向异性介质中，地震波的传播速度会随传播方向的变化而变化，这使得求解各向异性条件程函方程时，相速度的精确估计和计算变得非常复杂和困难，进而影响各向异性介质中走时和射线路径的计算精度和效率。为此，提出了一种基于相速度预测的射线追踪方法，该方法根据波的传播规律以及斯奈尔方程，推导出一种相速度预测公式，解决了各向异性条件程函方程中相速度求解困难的问题，实现了快速稳定的射线追踪。数值算例表明，本文所提出的改进算法明显提高了走时计算精度 ...

Probing vacuum birefringence by phase-contrast Fourier imaging under fields of high-intensity lasers
, 2011 In vacuum high-intensity lasers can cause photon-photon interaction via the process of virtual vacuum polarization which may be measured by the phase velocity shift of photons across intense fields.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Laser Ion Acceleration in a Near Critical Density Trap
Photonics, 2022 In order to accelerate ions by a laser, we go back to the original and the fundamental idea of how longitudinal field structure generation can be carried out in an ionized media and how particles may be trapped by the created wakefield.
