Abstract:
Electrical stimulation is an indispensible tool in studying electrically excitable tissues in neurobiology and neuroendocrinology. In this work, the consequences of high-intensity electrical stimulation on the release of catecholamines from adrenal gland slices were examined with fast-scan cyclic voltammetry at carbon fiber microelectrodes. A biphasic signal, consisting of a fast and slow phase, was observed when electrical stimulations typically used in tissue slices (10 Hz, 350 μA biphasic, 2.0 ms/phase pulse width) were applied to bipolar tungsten-stimulating electrodes. This signal was fou

<strong>Abstract </strong>Relying on the principles of bioelectricity, electrical stimulation assists in the exercise of artificial control over the nervous system. This mechanism propagates action potentials which transmit neural signals to target tissues for diagnostic or therapeutic purposes. Research efforts in electrical stimulation for the activation of compromised neuromuscular tissues have been focused on the control of skin sensation taking into account stimulation parameter such as the nature of the stimulating waveform.&nbsp; This paper is aimed at the simulation study of the bioele

Abstract:
The stapedial reflex (SR) can be obtained by the impedance method only when the middle ear is intact. In order to examine the function of the stapedius muscle in diseased ears, the recording of the stapedial electromyogram by an electrocochleographic (ECoG) method was considered. The SR was recorded simultaneously by the impedance method in ten normal subjects for comparison. The outputs of ECoC were averaged by a signal processor up to 200 times under a longer sweep time, and a large biphasic wave with a latency of about 11 ms was obtained on the ECoC records.

Abstract:
In situ measurements of extracellular pH by means of microelectrodes and in situ measurements of optical density were performed on aggregating cells of Dictyostelium discoideum. Early aggregation stage AX2 cells showed sinusoidal pH oscillations, which could be inhibited by the specific relay inhibitor caffeine, indicating that they were coupled to cAMP oscillations. Sometimes biphasic pH oscillations were found, which can be explained by the superposition of two harmonic pH oscillations. These harmonic oscillations might arise by gating of the cAMP signal; a part of the cells respond to every

Abstract:
Currently, electronics and iontronics in abiotic-biotic systems can only use electrons and single-species ions as unitary signal carriers. Thus, a mechanism of gating transmission for multiple biosignals in such devices is needed to match and modulate complex aqueous-phase biological systems. Here we report the use of cascade-heterogated biphasic gel iontronics to achieve diverse electronic-to-multi-ionic signal transmission. The cascade-heterogated property determined the transfer free energy barriers experienced by ions and ionic hydration-dehydration states under an electric potential field

Abstract:
Activation of Gqprotein-coupled receptors usually causes a biphasic increase in intracellular calcium concentration ([Ca2+]i) that is crucial for secretion in nonexcitable cells. In gastric enterochromaffin-like (ECL) cells, stimulation with gastrin leads to a prompt biphasic calcium response followed by histamine secretion. This study investigates the underlying signaling events in this neuroendocrine cell type. In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP3R) subtypes 1–3. The IP3R antagonist 2-aminoethoxydiphenyl borate abolished both gastrin-induc

This paper deals with the DC offset currents generated by a platinum electrode matrix during biphasic stimulation. A fully automated test bench evaluates the nanoampere range DC offset currents in a realistic and comprehensive scenario by using platinum electrodes in a saline solution as a load for the stimulator. Measurements are performed on different stimulation patterns for single or dual hexagonal stimulation sites operating simultaneously and alternately. The effectiveness of the return electrode presence in reducing the DC offset current is considered. Experimental results show how for

There are, and have been, many monitors designed to monitor depth of anaesthesia and to give an indication of awareness during surgery, which use electrical signals obtained from the human body.

Most, but not all, are based on the spontaneous EEG and the AER. Some have been designed to use properties of the ECG. Although useful, all of the discussed monitors have some shortcomings, and not all are 100% sensitive and specific to discriminate between con

Studies indicated that the damage of the optic nervehead (ONH), due to the biomechanical environment in and around the lamina cribrosa (LC), could be an important event leading to POAG [Morgan].

Introduction: aging is a multifactorial process that affects both the functionality and aesthetics of the body, including the skin, influenced by intrinsic (genetic) and extrinsic (environmental) factors. Fillers, especially those based on hyaluronic acid (HA), are the most preferred in aesthetic procedures due to their efficacy, safety, and ease of use. In the midface, the most visible signs of aging, such as wrinkles and furrows, are often treated with cross-linked HA (CHA), recognized worldwide for its ability to correct folds and restore volume.
