Electrical impedance tomography in acute respiratory distress syndrome

open access: yesCritical Care, 2018
Acute respiratory distress syndrome (ARDS) is a clinical entity that acutely affects the lung parenchyma, and is characterized by diffuse alveolar damage and increased pulmonary vascular permeability.

Electrical Impedance of Isolated Amnion

open access: yesBiophysical Journal, 1965
The electrical impedance of the guinea pig amniotic membrane was measured, under standardized conditions, over the frequency range of 20 to 7000 cycles/second. This impedance can be represented analytically by a simple frequency-dependent function which is precisely of the form of the Debye relaxation equation.

Electrical Impedance Tomography

open access: yesWiley Encyclopedia of Electrical and Electronics Engineering, 2019
Electrical Impedance Tomography (EIT) is a medical imaging technique which uses electrical stimulations and measurements at body-surface electrodes. From these data, images of the distribution of conductivity within the body are calculated by solving an ...

Broadband electrical impedance spectroscopy for dynamic electrical bio-impedance characterization

open access: yes, 2023
The electrical impedance of biological samples is known in the literature as Electrical Bioimpedance (EBI). The Electrical Bioimpedance enables to characterize physiological conditions and events that are interesting for physiological research and medical diagnosis.

Electrical Impedance of Cardiac Muscle [PDF]

open access: yesCirculation Research, 1961
Impedances of cat cardiac muscle and frog sartorius muscle were compared at several frequencies before and after interspace ion depletion. Strips of parallel fibers were obtained from papillary muscles and ventricular trabeculae. The impedances were measured in the direction of fiber orientation.

Electrical impedance of acupuncture meridians: the relevance of subcutaneous collagenous bands. [PDF]

open access: yesPLoS ONE, 2010
The scientific basis for acupuncture meridians is unknown. Past studies have suggested that acupuncture meridians are physiologically characterized by low electrical impedance and anatomically associated with connective tissue planes.

Ex vivo electrical bioimpedance measurements and Cole modelling on the porcine colon and rectum

open access: yesScientific Reports
Different pathological changes in the large intestine wall, associated with the development of different chronic diseases, including colorectal cancer, could be reflected in electrical bioimpedance readings. Thickness and composition of the mucus bilayer

Dose‐dependent induction of epithelial‐mesenchymal transition in 3D melanoma models by non‐thermal plasma treatment

open access: yesMolecular Oncology, EarlyView.
Non‐thermal plasma treatment of melanoma cells induced epithelial‐mesenchymal transition (EMT) in a dose‐dependent fashion. This report highlights the critical need to further investigate potential adverse effects of non‐thermal plasma for cancer therapy and to optimize treatment parameters for clinical translation. Despite the promising results of non‐
