A two-lane mechanism for selective biological ammonium transport

open access: yeseLife, 2020
The transport of charged molecules across biological membranes faces the dual problem of accommodating charges in a highly hydrophobic environment while maintaining selective substrate translocation.

Non-equilibrium statistical mechanics: from a paradigmatic model to biological transport [PDF]

open access: yes, 2011
Unlike equilibrium statistical mechanics, with its well-established foundations, a similar widely accepted framework for non-equilibrium statistical mechanics (NESM) remains elusive. Here, we review some of the many recent activities on NESM, focusing on

The Need for a Kinetics for Biological Transport

open access: yesBiophysical Journal, 1973
The traditional theory of transport across capillary membranes via a laminar Poiseuille flow is shown to be invalid. It is demonstrated that the random, diffusive nature of the molecular flow and interactions with the "pore" walls play an important role in the transport process.

On the blow-up criterion and global existence of a nonlinear PDE system in biological transport networks

open access: yesKinetic and Related Models, 2019
In this paper, we consider a parabolic-elliptic system of partial differential equations in the three dimensional setting that arises in the study of biological transport networks.

Erythrocyte fatty acid profiles in children are not predictive of autism spectrum disorder status: a case control study

open access: yesBiomarker Research, 2018
Biomarkers promise biomolecular explanations as well as reliable diagnostics, stratification, and treatment strategies that have the potential to help mitigate the effects of disorders.

Fractional Chemotaxis Diffusion Equations [PDF]

open access: yes, 2010
We introduce mesoscopic and macroscopic model equations of chemotaxis with anomalous subdiffusion for modelling chemically directed transport of biological organisms in changing chemical environments with diffusion hindered by traps or macro-molecular ...

Spin transport in helical biological systems [PDF]

open access: yesAIP Conference Proceedings, 2014
Motivated by the recent experimental demonstration of spin selective effects in monolayers of double-stranded DNA oligomers, our work presents a minimal model to describe electron transmission through helical fields. Our model highlight that the lack of inversion symmetry due to the chirality of the potential is a key factor which will lead to a high ...

Compartmental Modeling Approach: Application on Transdermal Delivery for In Vitro Drug Permeation Mechanism Analysis

open access: yesJournal of Food and Pharmaceutical Sciences, 2021
Compartmental modeling analysis was used to understand the transport mechanism of drugs in biological systems by computation presented as intercompartmental flows or material. This study was aimed to implement compartmental modeling analysis for in vitro

Electrochemical surface passivation of LiCoO2 particles at ultrahigh voltage and its applications in lithium-based batteries

open access: yesNature Communications, 2018
LiCoO2 is a cathode material widely used in lithium-ion batteries but suffers from solubilization of cobalt and structural disorder when the voltage is increased to release more capacity.
