FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

FEBS Open Bio, EarlyView.Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy
FEBS Open Bio, EarlyView.This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Effect of External Source Impedance on the Input Impedance of Digital Impedance Circuits
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020The input impedance of recently-introduced digital impedance circuits has been discovered to be dependent on the impedance of the external signal source. To address this problem, the theory for the dependence of digital impedance on external source resistance is presented.

Faradaic Impedances: Diffusion Impedance and Reaction Impedance
Journal of The Electrochemical Society, 1970Relative contributions of double‐layer and faradaic impedances have been studied for two typical cases involving important electrochemical processes. The faradaic impedance has been interpreted quantitatively in terms of models which describe either the mass transport or the reaction mechanism at the electrode.

Summary The technique of impedance plethysmography is described and its application to observation of lung volume changes in the horse at exercise is discussed. The results from horse at rest show that there is a close relationship between rate of lung volume change (flow rate) and the associated impedance changes during both ...

Impedance spectroscopy (IS) is a general term that subsumes the small-signal measurement of the linear electrical response of a material of interest (including electrode effects) and the subsequent analysis of the response to yield useful information about the physicochemical properties of the system.

Electrical Impedance Tomography
SIAM Review, 1999A mathematical model for electrical impedance tomography is described. This model is used for explaining the Rensselaer system. Some reconstruction algorithms are surveyed, especially the Moser algorithm. Some experimental tests are given.

ABSTRACTThe purpose of this review was to integrate recent evidence supporting the reliability of thoracic impedance plethysmography as an estimator of cardiodynamic function. Reports regarding the development of the method for NASA, and numerous investigations comparing impedance cardiography to indicator dilution and other methods were discussed.
