Spatiotemporal dynamics of Ca2+ signaling and its physiological roles

Proceedings of the Japan Academy. Series B, Physical and biological sciences, 2010
Changes in the intracellular Ca2+ concentration regulate numerous cell functions and display diverse spatiotemporal dynamics, which underlie the versatility of Ca2+ in cell signaling.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

Advanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Breakthrough Solution for Antimicrobial Resistance Detection: Surface‐Enhanced Raman Spectroscopy‐based on Artificial Intelligence

Advanced Materials Interfaces, EarlyView., 2023
This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

MiR-25 overexpression inhibits titanium particle-induced osteoclast differentiation via down-regulation of mitochondrial calcium uniporter in vitro

Journal of Orthopaedic Surgery and Research, 2022
Background Mitochondrial calcium uniporter (MCU) is an important ion channel regulating calcium transport across the mitochondrial membrane. Calcium signaling, particularly via the Ca2+/NFATc1 pathway, has been identified as an important mediator of the ...

Oscillatory Ca2+ Signaling in the Isolated Caenorhabditis elegans Intestine

The Journal of General Physiology, 2005
Defecation in the nematode Caenorhabditis elegans is a readily observable ultradian behavioral rhythm that occurs once every 45–50 s and is mediated in part by posterior body wall muscle contraction (pBoc).

Electrically Induced Negative Differential Resistance States Mediated by Oxygen Octahedra Coupling in Manganites for Neuronal Dynamics

Advanced Functional Materials, EarlyView.
The negative differential resistance is exploited, using a La0.67Sr0.33MnO3 thin film network to demonstrate various neuronal functionalities of the human brain, such as leaky‐integrate‐fire and oscillatory patterns. Transmission electron microscope studies show local modification in oxygen octahedra in the network leads to co‐existing phases ...

A nested bistable module within a negative feedback loop ensures different types of oscillations in signaling systems

Scientific Reports, 2023
In this article, we consider a double phosphorylation cycle, a ubiquitous signaling component, having the ability to display bistability, a behavior strongly related to the existence of positive feedback loops.

Bistable emergence of oscillations in structured cell populations [PDF]

arXiv, 2018
Biofilm communities of Bacillus subtilis bacteria have recently been shown to exhibit collective growth-rate oscillations mediated by electrochemical signaling to cope with nutrient starvation. These oscillations emerge once the colony reaches a large enough number of cells.

Signaling between intracellular Ca2+ stores and depletion-activated Ca2+ channels generates [Ca2+]i oscillations in T lymphocytes

The Journal of General Physiology, 1994
Stimulation through the antigen receptor (TCR) of T lymphocytes triggers cytosolic calcium ([Ca2+]i) oscillations that are critically dependent on Ca2+ entry across the plasma membrane.

Multidirectionally Patterned Interdigital Transducers for Enhancing Acoustofluidic Streaming with Flexible Printed Circuit Board

Advanced Functional Materials, EarlyView.
A reconfigurable and multidirectional interdigital transducer (M‐IDT) on a flexible printed circuit board provides a practical platform for acoustofluidic research. It simplifies and accelerates prototyping, enabling cost‐effective exploration of wave modes and fluid dynamics.
