Justification of Application of Complex-Quantitative Methods for an Estimation of Qualities of Materials in the Conditions of a High-Speed Load

Успехи физики металлов, 2016
Due to the fact that in the modern metrological database there is no clear methodology for estimating quality of materials under the conditions of shock and high-speed loads, in this work the analysis of dynamic properties of metallic materials at the ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Lyapunov functions for linear nonautonomous dynamical equations on time scales [PDF]

, 2006
The existence of a Lyapunov function is established following a method of Yoshizawa for the uniform exponential asymptotic stability of the zero solution of a nonautonomous linear dynamical equation on a time scale with uniformly bounded ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Dynamic Loadings Of Precastretaining Walls

Kirkuk University Journal-Scientific Studies, 2007
The research aims for the selection of a suitable retaining wall amongst two types of precast concrete walls under dynamic loads (wave pressure). The first wall is of a triangular cross section and has the dimensions (3)m (in height) by (2.2) m (in width) by (0.25-0.3) m (in thickness) and the width of piece (1.44) m. The second wall has dimensions of (
