Diabetologia
. 2020 Feb;
63(5):1066-1071.
PMID: 32030469
Aims/hypothesis: We examined the effect of a standardised sympathetic stimulus, incremental adrenaline (epinephrine) infusion on cardiac repolarisation in individuals with type 1 diabetes with normal autonomic function, subclinical autonomic neuropathy...

PMID: 29051738
Epilepsy is a neurological disorder that causes changes in the autonomic nervous system. Heart rate variability (HRV) reflects the regulation of cardiac activity and autonomic nervous system tone. The early...

Arch Endocrinol Metab
. 2017 Jul;
61(6):534-541.
PMID: 28724054
Objective: Diabetes mellitus is associated with significant morbidity and mortality, and education is known to play a key role in managing this disease. This study addresses the effects of a...

Diabetes Care
. 2017 Feb;
40(5):655-662.
PMID: 28213374
Objective: Hypoglycemia may exert proarrhythmogenic effects on the heart via sympathoadrenal stimulation and hypokalemia. Hypoglycemia-induced cardiac dysrhythmias are linked to the "dead-in-bed syndrome," a rare but devastating condition. We examined...

Artif Organs
. 2014 Jul;
39(2):192-7.
PMID: 25041415
Electrochemotherapy is a combination of high electric field and anticancer drugs. The treatment basis is electroporation or electropermeabilization of the cell membrane. Electroporation is a threshold phenomenon and, for efficient...

Annu Int Conf IEEE Eng Med Biol Soc
. 2013 Feb;
2012:5494-7.
PMID: 23367173
There are several models of decomposition of the electrocardiogram (ECG). Some of these models are intended to describe the ECG signal, and others are more specific to extract the relevant...

IEEE Trans Biomed Eng
. 2012 Sep;
59(10):2965-73.
PMID: 22996724
Conductivity measurements in suspensions of biological cells have been used since many years for electroporation effectiveness evaluation. However, conductivity modeling by means of instantaneous values of current and voltage during...

Epilepsia
. 2012 May;
53(8):1314-21.
PMID: 22642646
Purpose: Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures. Little is known about ictal autonomic nervous system (ANS) activity changes in epilepsy and PNES. This study compares ictal heart rate...

PMID: 21193368
An intense electric field can be applied to increase the membrane conductance G(m) and consequently, the conductivity of cell suspension. This phenomenon is called electroporation. This mechanism is used in...
