Numerical study of turbulent separated flows in axisymmetric diffusers based on a two-fluid model

open access: yesInternational Journal of Applied Mechanics and Engineering
This paper discusses a numerical study of turbulent flow at Re = 1.56×104 in an axisymmetric diffuser with half-angle expansion α=14°, 18° и 90°. The results obtained are compared with known experimental data.

Characterization of apolipoprotein B-containing lipoproteins separated by preparative free flow isotachophoresis.

open access: yesJournal of Lipid Research, 1990
Preparative free flow isotachophoresis (ITP) was used for the fractionation of apoB-containing lipoproteins (d less than 1.063 g/ml) from fasting and postprandial sera derived from normolipidemic individuals.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

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.

Сritical Speed Numerical Determination for Arbitrary Tube Bundle in Fluid Flow

open access: yesМеханика машин, механизмов и материалов, 2017
On the basis of the analysis results of experimental behavior of tube bundles under separated flow, the mathematical model for hydroelastic vibration excitation mechanism of tube bundle was developed.

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.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
