A CMRR enhancement circuit by employing auxiliary buffer of capacitively coupled instrumentation amplifier for neural signal recording

Electronics Letters, 2021
Here, a common‐mode rejection ratio (CMRR) enhancement circuit is proposed by employing an auxiliary buffer (AB) to the pseudo resistors of the capacitively coupled instrumentation amplifier (CCIA).

A Fully Differential Analog Front-End for Signal Processing from EMG Sensor in 28 nm FDSOI Technology

Sensors, 2023
This paper presents a novel analog front-end for EMG sensor signal processing powered by 1 V. Such a low supply voltage requires specific design steps enabled using the 28 nm fully depleted silicon on insulator (FDSOI) technology from STMicroelectronics.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Self-Biased Ultralow Power Current-Reused Neural Amplifier With On-Chip Analog Spike Detections

IEEE Access, 2019
An ultralow power 0.6 V neural amplifier with on-chip analog spike detection is presented. A capacitively-coupled instrumentation amplifier (CCIA) with the current-reused and self-biased scheme is proposed to reduce the overall power consumption and to ...

Twin‐Wire Sensor Networks

Advanced Sensor Research, 2023
A fundamental limit to high‐density sensing is that adding sensors increases the number of wires, pads, and interconnections. This problem is even worse for low‐values resistive or impedance sensors which, for high accuracy, require 4‐wire measurements ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
