Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Heat Transfer Calculations in Barrel Cover of 35 mm Naval Armament System Gun [PDF]

open access: yesProblemy Mechatroniki, 2018
This paper presents the results of numerical simulations of non-stationary heat transfer in a 35 mm anti-air gun barrel cover made of composite materials. The cover protects the gun against weather conditions, including sea water effects, and serves as a

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Understanding the mechanisms of lung mechanical stress [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2006
Physical forces affect both the function and phenotype of cells in the lung. Bronchial, alveolar, and other parenchymal cells, as well as fibroblasts and macrophages, are normally subjected to a variety of passive and active mechanical forces associated with lung inflation and vascular perfusion as a result of the dynamic nature of lung function. These

Vibrations and Stability of a Plate in Supersonic Flow Subjected to a Follower Force, and Having a Hinged External Support and a Resilient Attenuation Internal Support [PDF]

open access: yesProblemy Mechatroniki, 2018
The vibrations and stability of a plate having a finite length were considered in a flat supersonic flow, having adopted an assumption that one of the edges of the plate has a hinged support, and the other edge is free.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Zebrafish epiboly: mechanics and mechanisms

open access: yesThe International Journal of Developmental Biology, 2010
Gastrulation involves of a series of coordinated cell movements to organize the germ layers and establish the major body axes of the embryo. One gastrulation movement is epiboly, which involves the thinning and spreading of a multilayered cell sheet. Epiboly plays a prominent role in zebrafish gastrulation and studies of zebrafish epiboly have provided

Reliability Analysis of Ventube Fan Rotor [PDF]

open access: yesProblemy Mechatroniki, 2015
Discs of ventube fan rotor were chosen as an object of the study. As a result of an analytical calculation, distribution of radial and circumferential stress and safety factor along rotor’s disc radius was calculated.
