The movement of a molecule across a typical plant cell (about50μm) takes approximately 2.5s. At this rate calculate how many years it would take for the movement of molecules over a distance of 1 m within a pl
molecules at the fluid-CNT interface, using molecular dynamics simulations. By excluding the fluid-CNT interfaces, superfast diffusion of methane is found in an infinite CNT having a diameter of 0.81 nm, which is more than 2 orders of magnitude higher than that in larger CNTs. However, the...
In recent years, there has been considerable progress in determining the soil properties that influence the structure of the soil microbiome. By contrast, the effects of microorganisms on their soil habitat have received less attention with most previous

The recovery of fluorescence intensity in the bleached region occurs over time due to the diffusion or movement of unbleached fluorescent molecules from the surrounding areas. This fluorescence recovery allows the visualization of molecular dynamics and processes (e.g. turnover, mobility, interactions, ...
(s), 2023 ABSTRACT The movement of water molecules at the atomic scale within the calcium silicate hydrate (C–S–H) gel pores serves a dual role: it creates an environment for harm- ful chemical reactions within the pores and functions as a carrier for the transport of detrimental ions, ...

of the BBB responsible for selective permeability to small lipophilic molecules [7]. These cells tightly bind together to prevent paracellular drug transport across the BBB and contribute to the high transendothelial resistance (TEER) that limits the passive diffusion of external compounds between the ...
Currently, the most widely used ap- proach is the administration of targeted monoclonal antibodies (mAbs) directed against regulatory immune checkpoint molecules that inhibit T cell activation [1]. At present, six immune checkpoint inhibitors (ICIs) are approved by the U.S Food and Drug ...
T. brucei motility is crucial for movement through host tissues and provides a surprising immune-evasion mechanism. In addition to motility, the T. brucei flagellum is an important morphogenetic hub that controls cell shape and size, directs organelle segregation and governs cell division. These ...
