Suppression of crosstalk in multielectrode arrays with local shielding

open access: yesFrontiers in Nanotechnology, 2022
Electrical crosstalk can constrain the performance of multielectrode arrays in electro- and neurophysiology, in terms of both stimulation and recording.

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

open access: yes, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Thiol Modifications in the Extracellular Space—Key Proteins in Inflammation and Viral Infection

open access: yesFrontiers in Immunology, 2022
Posttranslational modifications (PTMs) allow to control molecular and cellular functions in response to specific signals and changes in the microenvironment of cells. They regulate structure, localization, stability, and function of proteins in a spatial

Generalized cable formalism to calculate the magnetic field of single neurons and neuronal populations

open access: yes, 2014
Neurons generate magnetic fields which can be recorded with macroscopic techniques such as magneto-encephalography. The theory that accounts for the genesis of neuronal magnetic fields involves dendritic cable structures in homogeneous resistive ...

Real-Time Amperometric Recording of Extracellular H2O2 in the Brain of Immunocompromised Mice: An In Vitro, Ex Vivo and In Vivo Characterisation Study

open access: yesSensors, 2017
We detail an extensive characterisation study on a previously described dual amperometric H2O2 biosensor consisting of H2O2 detection (blank) and degradation (catalase) electrodes.

Extracellular guanosine regulates extracellular adenosine levels

open access: yesAmerican Journal of Physiology-Cell Physiology, 2013
The aim of this investigation was to test the hypothesis that extracellular guanosine regulates extracellular adenosine levels. Rat preglomerular vascular smooth muscle cells were incubated with adenosine, guanosine, or both. Guanosine (30 μmol/l) per se had little effect on extracellular adenosine levels.

Glucose availability and sensitivity to anoxia of isolated rat peripheral nerve [PDF]

open access: yes, 1991
The contrast between resistance to ischemia and ischemic lesions in peripheral nerves of diabetic patients was explored by in vitro experiments. Isolated and desheathed rat peroneal nerves were incubated in the following solutions with different glucose ...
