Transplacental transfer mechanism of organochlorine pesticides: An in vitro transcellular transport study

open access: yesEnvironment International, 2020
Recent studies show that, even after being banned for agricultural applications for over 30 years, organochlorine pesticides (OCPs), including hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethane (DDT) and its metabolites (DDXs), can still ...

Functional Roles of the Conserved Amino Acid Sequence Motif C, the Antiporter Motif, in Membrane Transporters of the Major Facilitator Superfamily

open access: yesBiology, 2023
The biological membrane surrounding all living cells forms a hydrophobic barrier to the passage of biologically important molecules. Integral membrane proteins called transporters circumvent the cellular barrier and transport molecules across the cell ...

How molecular motors work in the crowded environment of living cells: coexistence and efficiency of normal and anomalous transport. [PDF]

open access: yesPLoS ONE, 2014
Recent experiments reveal both passive subdiffusion of various nanoparticles and anomalous active transport of such particles by molecular motors in the molecularly crowded environment of living biological cells.

Uptake and Transport of Naringenin and Its Antioxidant Effects in Human Intestinal Epithelial Caco-2 Cells

open access: yesFrontiers in Nutrition, 2022
Naringenin, a flavanone, has been reported for a wide range of pharmacological activities. However, there are few reports on the absorption, transport and antioxidant effects of naringenin.

A Reaction–Diffusion–Advection Model for the Establishment and Maintenance of Transport-Mediated Polarity and Symmetry Breaking

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
Cell polarity is a fundamental process in many different cell types. The yeast cell Saccharomyces cerevisiae provides an exemplary model system to study the underlying mechanisms. By combining biological experiments and mathematical simulations, previous

Cl−-ATPases: biological active transporters

open access: yesComparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2001
Five widely documented mechanisms of chloride transport across plasma membranes are: anion-coupled antiport; sodium and hydrogen-coupled symport; Cl- channels; and an electrochemical coupling process. No genetic evidence has yet been provided for primary active chloride transport despite numerous reports of cellular Cl(-)-stimulated ATPases co-existing,

Cycling in London: a study of social and cultural factors in transport mode choice: a final report to Smarter Travel Unit, Transport for London [PDF]

open access: yes, 2010
This report was commissioned to explore the reasons for differences in transport mode choice across population groups in London, to support the work of Transport for London and partner organisations in extending active transport in the capital.

Influence of electric potential-induced by atmospheric pressure plasma on cell response

open access: yesScientific Reports, 2023
Plasma irradiation leads not only active species, but also reactive chemical species, ultraviolet light, electric fields, magnetic fields, and shock waves. To date the effects of reactive chemical species have been mainly discussed.
