Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Double-Diffusive Convection of Synovial (Couple-Stress) Fluid in the Presence of Hall Current Through a Porous Medium

open access: yesInternational Journal of Applied Mechanics and Engineering, 2018
An investigation made on the effect of Hall currents on double-diffusive convection of a compressible synovial (couple-stress) fluid in the presence of a horizontal magnetic field through a porous layer is considered.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

A 7T2C Pixel Circuit Compensating for TFT Threshold Voltage Shift in Active-Matrix Simultaneous Neurostimulation

open access: yesIEEE Journal of the Electron Devices Society
Implantable neuroprostheses require stimulators with a high number of channels and mechanical flexibility. Organic thin-film transistors (OTFTs) are potential for flexible circuits and large-area bioelectronic systems.

Modulational instability of coupled ring waveguides with linear gain and nonlinear loss

open access: yesScientific Reports, 2017
We consider a nanostructure of two coupled ring waveguides with constant linear gain and nonlinear absorption - the system that can be implemented in various settings including polariton condensates, optical waveguides or atomic Bose-Einstein condensates.

Vortex-induced dissipation in narrow current-biased thin-film superconducting strips

open access: yes, 2011
A vortex crossing a thin-film superconducting strip from one edge to the other, perpendicular to the bias current, is the dominant mechanism of dissipation for films of thickness d on the order of the coherence length XI; and of width w much narrower ...

Stable ischemic heart disease in women: current perspectives

open access: yesInternational Journal of Women's Health, 2017
Cardiovascular disease is the leading cause of death in women accounting for 1 in every 4 female deaths. Pathophysiology of ischemic heart disease in women includes epicardial coronary artery, endothelial dysfunction, coronary vasospasm, plaque erosion and spontaneous coronary artery dissection. Angina is the most common presentation of stable ischemic

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Study of the Electrochemical Behavior of Histamine Using a Nafion®-Copper(II) Hexacyanoferrate Film-Modified Electrode.

open access: yesInternational Journal of Electrochemical Science, 2010
A study on the electrochemical behavior of histamine species in aqueous medium is described. A glassy carbon electrode chemically modified with copper(II) hexacyanoferrate (CuHCFe) film and covered with Nafion® film was employed.
