Finite-size effects in intracellular microrheology [PDF]

, 2006
We propose a model to explain finite-size effects in intracellular microrheology observed in experiments. The constrained dynamics of the particles in the intracellular medium, treated as a viscoelastic medium, is described by means of a diffusion equation in which interactions of the particles with the cytoskeleton are modelled by a harmonic force ...

Physical Principles Underlying the Complex Biology of Intracellular Phase Transitions.

Annual Review of Biophysics, 2020
Many biomolecular condensates appear to form via spontaneous or driven processes that have the hallmarks of intracellular phase transitions. This suggests that a common underlying physical framework might govern the formation of functionally and ...

GUT MICROSYMBIOCENOSIS IN CHILDREN WITH REACTIVE ARTHRITIS

Журнал микробиологии, эпидемиологии и иммунобиологии, 2016
Aim. To study the state of gut microsymbiocenosis in children with reactive arthritis (RA), with the assessment of biofilm formation (BFF) of microsymbionts and the ability to change cytokine levels (their anticytokine activity) in vitro.

Intracellular biomineralization in bacteria [PDF]

Frontiers in Microbiology, 2014
Microorganisms have populated the Earth for billions of years and their activities are important forces shaping our planetary environments through biogeochemical cycles. In particular, microbial biomineralization that selectively take up environmental elements and deposit minerals either intracellularly or extracellularly is of great interest, because ...

Intracellular mechanisms underlying the nicotinic enhancement of LTP in the rat dentate gyrus [PDF]

, 2008
We have previously shown that activation of nicotinic acetylcholine receptors (nAChRs) enhanced long-term potentiation (LTP) in the rat dentate gyrus in vitro via activation of α7 nAChR. In the present studies, mechanisms underlying the acute and chronic

Optical dispersions through intracellular inhomogeneities [PDF]

Phys. Rev. Research 5, L022043 (2023), 2022
Transport of intensity equation (TIE) exhibits a non-interferometric correlation between intensity and phase variations of intermediate fields (e.g., light and electron) in biological imaging. Previous TIE formulations have generally assumed a free space propagation of monochromatic coherent field functions crossing phase distributions along a ...

Fast solver for diffusive transport times on dynamic intracellular networks [PDF]

SIAM J. Appl. Mat., 84(3), S476-S492, 2024, 2022
The transport of particles in cells is influenced by the properties of intracellular networks they traverse while searching for localized target regions or reaction partners. Moreover, given the rapid turnover in many intracellular structures, it is crucial to understand how temporal changes in the network structure affect diffusive transport.
