Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

Molecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Nonreciprocal Scattering by PT-symmetric stack of the layers

, 2015
The nonreciprocal wave propagation in PT-symmetric periodic stack of binary dielectric layers characterised by balances loss and gain is analysed. The main mechanisms and resonant properties of the scattered plane waves are illustrated by the simulation ...

Dynamics of electron beams in the solar corona plasma with density fluctuations [PDF]

, 2001
The problem of beam propagation in a plasma with small scale and low intensity inhomogeneities is investigated. It is shown that the electron beam propagates in a plasma as a beam-plasma structure and is a source of Langmuir waves.

Understanding and measuring mechanical signals in the tumor stroma

FEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

Circular symmetric Airy beam with the inverse propagation of the abruptly autofocusing Airy beam [PDF]

arXiv, 2020
In this letter, we introduce a new class of light beam, the circular symmetric Airy beam (CSAB), which arises from the extensions of the one dimensional (1D) spectrum of Airy beam from rectangular coordinates to cylindrical ones. The CSAB propagates at initial stages with a single central lobe that autofocuses and then defocuses into the multi-rings ...

Even-odd effect in higher-order holographic production of electron vortex beams with nontrivial radial structures [PDF]

Phys. Rev. A99, 013608 (2019), 2019
Structured electron beams carrying orbital angular momentum are currently of considerable interest, both from a fundamental point of view and for application in electron microscopy and spectroscopy. Until recently, most studies have focused on the azimuthal structure of electron vortex beams with well-defined orbital angular momentum.

Protein crystallization and structure determination at room temperature in the CrystalChip

FEBS Open Bio, Volume 15, Issue 4, Page 532-541, April 2025.
This protocol describes the implementation of a simple and user‐friendly microfluidic device called CrystalChip that allows the production of crystals by the counter‐diffusion method and their in situ analysis by serial crystallography. As an illustration, it is applied to determine the 3D structure of three proteins from data collected at room ...

Towards numerical simulation of yarn insertion on air-jet weaving looms [PDF]

, 2019
In this research a structural solver and flow solver are coupled to simulate the motion of a nylon yarn as it is launched into the atmosphere by a main nozzle of an air-jet weaving loom. The high-speed air flow, large displacements of the yarn, 3D-nature

Cost‐effective and simple flow cytometry quantification of receptor‐mediated autophagy using fluorescent tagging

FEBS Open Bio, Volume 15, Issue 4, Page 587-598, April 2025.
Mitophagy, the selective degradation of damaged mitochondria, is crucial for cellular health and function. This study introduces a rapid and efficient flow cytometry method using GFP‐BNIP3L/NIX to accurately quantify mitophagy. Our approach can be adapted to use any fluorescent‐tagged selective autophagy receptor, enabling direct and rapid analysis of ...

Generalized Bessel beams with two indices [PDF]

, 2014
We report on a new class of exact solutions of the scalar Helmholtz equation obtained by carefully engineering the form of the angular spectrum of a Bessel beam. We consider in particular the case in which the angular spectrum of such generalized beams has, in the paraxial zone, the same radial structure as Laguerre-Gaussian beams.
